Creationism News -- July 2012 创造论新闻 – 2012年7月 Dedicated to David Coppedge who sacrificed his career as the Head Systems Administrator for the Cassini Spacecraft in JPL to honor the Creator of the Universe. He also spent literally thousands of hours to make his excellent websites. The contents of this presentation were taken from David Coppedge’s website http://crev.info. Pray for the results of his discrimination lawsuit against JPL. Pastor Chui http://ChristCenterGospel.org [email protected] 7/7/2015 1 Evolutionists Taking Credit for Biomimetics 进化论者信用仿生学 Biomimetics is all about design – intelligent design, mimicking the superb designs found in nature. Why, then, are some scientists claiming evolutionary theory is where the biomimetic beef is? Gecko toes: the impossible dream. PhysOrg titled an article in big, bold print: “How sticky toepads evolved in geckos and what that means for adhesive technologies.” Based on a paper 7/7/2015 2 in PLoS ONE Evolutionists Taking Credit for Biomimetics 进化论者信用仿生学 PhysOrg filled its coverage with the e-word evolution or its derivatives no less than 15 times. The amazing thing, though, is that believing the research paper requires accepting the authors’ claim that geckos “evolved” their intricate toe pads that allow them to walk on walls and ceilings multiple times: “Geckos have independently evolved their trademark sticky feet as many as 11 times, and lost them nine times, according to research published June 27 in the open access journal PLoS ONE.” The lead author, Tony Gamble (U of Minnesota) seemed astonished himself at the gecko’s luck in the mutational lottery: “To discover that geckos evolved sticky toepads again and again is 7/7/2015 3 amazing,” he exclaimed. Evolutionists Taking Credit for Biomimetics 进化论者信用仿生学 What, exactly, does evolutionary theory contribute to the engineers who want to copy gecko technology? It’s not apparent how speculating about gecko habitat changes in the unobservable past would help a design engineer, nor does this statement by a co-author of the paper: “The loss of adhesive pads in dune-dwelling species is an excellent example of natural selection in action.” Where does he put that on the design specifications, if he is trying to use intelligent design? Maybe this statement about repeated 7/7/2015 4 evolution will help: Evolutionists Taking Credit for Biomimetics 进化论者信用仿生学 Repeated evolution is a key phenomenon in the study of evolutionary biology. A classic example is the independent evolution of wings in birds, bats and pterosaurs. It represents a shared solution that organisms arrived at separately to overcome common problems. Our representative engineer is still shaking his head. The authors tell about how they studied the family trees of more than 100 gecko genera. “The family tree will also allow the authors to revise gecko taxonomy to best reflect the group’s evolutionary history.” The engineer is still 7/7/2015 5 wondering how this helps. Evolutionists Taking Credit for Biomimetics 进化论者信用仿生学 The best attempt to give evolution credit is at the end of the PhysOrg article. Play engineer and see if it tells you how to design a sticky-foot robot any better than if you didn’t know anything about gecko evolution, but were just intrigued by the mechanism on living geckos: “Gaining a better understanding of the complex evolutionary history of gecko toepads allows bio-inspired engineers to learn from these natural designs and develop new applications,” says co-author Anthony Russell, of the University 7/7/2015 6 of Calgary. Evolutionists Taking Credit for Biomimetics 进化论者信用仿生学 While scientists have a good understanding of how geckos stick at the microscopic level, they are just beginning to understand how geckos use their adhesive toepads to move around complex environments in the wild. Learning how gecko toepads have evolved to move in nature is an important step in developing robotic technologies that can do similar things. “It’s one thing to stick and unstick a piece of ‘gecko tape’ to a smooth surface in a lab, but something else altogether to get a robotic gecko to move across a complicated landscape in the real world and stick to all the different shapes and textures it will encounter,” says Gamble. Examining the repeated evolution of gecko toepads will let scientists find common ways natural selection solved these problems and focus on the characteristics shared across different gecko species. It seems that information could be gained from observing living geckos without knowing anything about a presumed 7/7/2015 7 evolutionary history. Evolutionists Taking Credit for Biomimetics 进化论者信用仿生学 Sponge semiconductors: Evolution appeared in the title of another biomimetics article, this time on New Scientist: “Evolution could generate new semiconducting structures.” Here, evolutionary theory was not claimed to provide insight on how to design things, as in the previous article. Instead, the engineers look at sponges and their proteins, and then thought they could do better. They randomly varied the proteins with the goal of discovering structures useful for the semiconductor industry. This is another case of artificial selection, therefore – not undirected, unguided, purposeless evolution in the Darwinian sense. It’s like cattle breeding; i.e., intelligent design.8 7/7/2015 Evolutionists Taking Credit for Biomimetics 进化论者信用仿生学 Self-assembling proteins: Another biomimetics article on Science Daily gave evolution only a brief, passing mention. In this story, researchers at the University of Montreal came up with a better way to visualize how proteins self-assemble in living cells. “Enabling bioengineers to design new molecular machines for nanotechnology applications is one of the possible outcomes” of the study – that’s the biomimetics angle. What’s the evolution angle or contribution to understanding? Proteins are made of long linear chains of amino acids, which have evolved over millions of years to self-assemble extremely rapidly — often within thousandths of a split 7/7/2015 9 second — into a working nanomachine. Evolutionists Taking Credit for Biomimetics 进化论者信用仿生学 Someone joked that a Senator is someone who looks which way the crowd is going, runs up to the front of the line and declares himself their leader. That’s what Senator Charlie D. from Down-Down-Down House is trying to do. He’s leading a shrinking band of disciples down the hill to the Museum of Has-Beens. 7/7/2015 10 Evolutionists Taking Credit for Biomimetics 进化论者信用仿生学 Darwinists, keep your grubby hands off of biomimetics. It doesn’t belong to you. You have nothing to contribute. If you want us to believe that geckos evolved toes so well designed they use Van der Waals atomic forces to stick to ceilings, and not only that, but did it 11 times independently, then we will thank you (for the funny joke). If you want to tell us that evolution produced proteins that assemble within thousandths of a split second into working nanomachines by chance over millions 7/7/2015 11 of years, sayonara. Evolutionists Taking Credit for Biomimetics 进化论者信用仿生学 The rapid rise of biomimetics over the last decade is a sign that people are tired of useless just-so stories. Real cutting-edge science for the 21st century, on the rise in both medical genetics and biomimetics, is based on the implicit assumption that natural structures are intelligently designed and full of potential for enlightenment, wonder, invention, benefit, application, and progress. 7/7/2015 12 Dinosaur Feather Story Gets Hairy 恐龙羽毛的故事生了毛 Another “feathered dinosaur” story has caused a flap and flurry of news reports. But are they really feathers, and do they help evolutionary theory? An exceptionally preserved juvenile in typical “dinosaur death pose” was unearthed in German limestone and given the name Sciurumimus (“squirrelmimic”). Labelled Jurassic by the researchers who announced the discovery in PNAS,1 this is the first non-coelurosaur species described with integumentary structures. It is leading some to postulate that all the branches of dinosaurs had “feathers,” as stated in National Geographic’s article: “‘Probably all dinosaurs were feathered,’ scientist13 7/7/2015 Dinosaur Feather Story Gets Hairy 恐龙羽毛的故事生了毛 One will look in vain, though, for veined feathers with barbs and barbules as found in birds. The authors label the structures “type 1 feathers,” meaning single filaments protruding from the skin (see 9/15/2011 entry). They are actually little more than fuzz, barely noticeable in the photos. Co-author Helmut Tischlinger said, “Under ultraviolet light, remains of the skin and feathers show up as luminous patches around the skeleton.” 7/7/2015 14 Dinosaur Feather Story Gets Hairy 恐龙羽毛的故事生了毛 Some, like Brian Switek at Nature News, dub them “protofeathers.” He wrote, Palaeontologist Paul Barrett of London’s Natural History Museum agrees that the structures on Sciurumimus are probably protofeathers. Although additional geochemical work is needed to study the features’ details, Barrett says, the fossilized wisps are very similar to the fuzz seen on other dinosaurs. But he notes that the presence of these filaments among all dinosaurs is “speculation”. Feathery structures might be a common feature of dinosaurs, but it’s also possible that they evolved multiple times. “We need more examples in both non-coelurosaurian theropods, and particularly in the other big dinosaur groups, before we can really speculate that these features are a 7/7/2015 15 character of dinosaurs as a whole,” Barrett says. Dinosaur Feather Story Gets Hairy 恐龙羽毛的故事生了毛 Reporters seem unsure what to make of the news. Coauthor Mark Norell said, according to Science Daily, “This is a surprising find,” noting that it appeared in the same limestone in northern Bavaria as Archaeopteryx (discovered 150 years ago), that was fully fledged with flight feathers: meaning, at the very least, that this creature and birds with powered flight were contemporaries. Clearly whatever the fuzz was on this creature, it had nothing to do with flight. Though the juvenile in the fossil was only 28″ long, “Adult megalosaurs reached about 20 feet in length and often weighed more than a ton,” Science Daily reported. “They were active predators, which probably also hunted other large dinosaurs.” Not even believers in dinosaur-to-bird evolution think this creature was closely 16 7/7/2015 related to birds. Dinosaur Feather Story Gets Hairy 恐龙羽毛的故事生了毛 Of note is that this fossil came from a private collector and looks, at first glance, almost too good to be true. Assuming it is authentic and trustworthy, though, paleontologists have their work cut out for them. “Although the feathers look similar among different dinosaur groups, it’s still possible the trait evolved independently, without a common ancestor,” National Geographic suggested (look for phrase “repeated evolution” in the 7/01/2012 entry). Everyone seems to agree there’s not enough information to make sweeping conclusions. NG reporter Christine Dell’Amore quoted Corwin Sullivan saying, “We paleontologists are going to need to find more fossils—of things even less closely related to birds than Sciurumimus—to be 17 7/7/2015 sure.” Dinosaur Feather Story Gets Hairy 恐龙羽毛的故事生了毛 Moreover, the discovery “upends [the] feather theory,” National Geographic headlined, and also upends the portrayal of dinosaurs as “overgrown lizards.” Switek remarked, “If so, we will have to start thinking about what kind of feathery covering these creatures display when we depict them in art and film.” 1. Rauhut, Foth, Tischlinger and Norell, “Exceptionally preserved juvenile megalosauroid theropod dinosaur with filamentous integument from the Late Jurassic of Germany,” PNAS, published online July 2, 2012, doi: 10.1073/pnas.1203238109. 7/7/2015 18 Dinosaur Feather Story Gets Hairy 恐龙羽毛的故事生了毛 You have type 1 protofeathers, too. They’re called hairs. Imagine finding a fossil skeleton of a horse so well preserved, impressions of its mane and tail were clearly seen in the rock (but strangely, none of the internal organs). Would you be justified in saying that horses were evolving flight? Horsefeathers. Would it make any sense to say that the trait originated further back than expected, implying that the common ancestor of birds and Pegasus had protofeathers? If you didn’t already “know” the evolutionary story about how mammals, dinosaurs and birds are supposed to have evolved, it would be a similar inferential fallacy. There’s still something very weird about these “feathered dinosaur” discoveries. They are found in Germany or China, often involve the same fossil-hunters, and often come from private collectors. 7/7/2015 19 Dinosaur Feather Story Gets Hairy 恐龙羽毛的故事生了毛 Even giving the evolutionists the maximum credibility about the authenticity of the fossils, they still usually create problems for Darwin. They don’t show a clear path from fuzz to flight. The “protofeathers” are on the wrong animals. They have an unknown function. Their dates overlap, or belong in the wrong eras. They don’t show a progression in complexity over time till true powered flight is thought to have evolved. They are either simple protrusions, or complex feathers found on animals that clearly used them for flying or gliding. Given how quickly animals equipped for flight could conquer the globe, one would expect to find them everywhere (compare pterosaurs, flying insects, 7/7/2015 20 bats). Informed skepticism is still in order. Dinosaur Feather Story Gets Hairy 恐龙羽毛的故事生了毛 Another lesson is how readers can be distracted by the wrong questions. Stop listening to the evolution tales, and ask other questions: Why are dinosaurs so often found in the typical death pose, suggesting rapid suffocation in water (11/23/2011)? Why are they exquisitely preserved? Why do so few reporters fail to question the dates and stories of the Darwinists? Why don’t they focus, instead, on the high levels of complexity required to have an animal run, hunt, fly, or live 7/7/2015 21 at all? Animalympics 动物奥运会 As summer Olympics season approaches, we should remember that we humans are not the only ones with some amazing physical abilities. Giraffe-alympics: Humans may dive from 10 meters or more, but the distance between heart and head does not change significantly. Giraffes, by contrast, can lower their heads 18 feet to drink water without their brains exploding. Then they can take off galloping if a predator approaches, all the while maintaining constant fluid pressure. PhysOrg wrote in a short article, “Giraffes are living proof that cells’ pressure matters.” It’s about researchers in France who came up with a better model to explain fluid pressure in tissues when cells divide. The new model explains how a tissue maintains a steady state between cell division and cell death. “If that were the case, very tall organisms such as giraffes could not exist, because the cells in their lower body would die under pressure.” 7/7/2015 22 Animalympics 动物奥运会 Lizard diving competition: Like cats, lizards land on their feet after a fall; but unlike cats, they do it with a twist of the tail. “Lizards in their natural environment encounter various situations where they could fall, PhysOrg explained. “For instance, they could fall while fighting over territory, seeking food, or even mating. To avoid injuries, they must have a way to turn themselves during a fall to land safely on their feet. ” PhysOrg reported how researchers from UC Berkeley took high-speed video of green anoles and flat-tailed house geckos to see how they do it. They were impressed enough to design a Righting Bot robot that imitates the tail-flick trick. They believe their findings “could also help engineers to design air– or land-based robots with better stability.” 7/7/2015 23 Animalympics 动物奥运会 Ageless diving seabirds: One might think that animals with the most strenuous lives would age sooner, but guillemots (a species of diving bird) maintain fitness until their last dive, without showing signs of aging. “The guillemots — which look similar to penguins but can fly — have the highest flight costs of any bird and expend substantial energy for diving,” Science Daily explained. “Their high metabolisms and frequent dives should produce oxidative stress, causing the birds to deteriorate as they age. But, the researchers discovered that the birds stay fit and active as they grow older, maintaining their flying, diving, and foraging abilities.” Kyle Elliott (U of Manitoba) remarked, “Not only do these birds live very long, but they maintain their energetic lifestyle in a very extreme environment into old age.” Maybe they could help humans in the Aging Competition in which everyone is participating. 7/7/2015 24 Animalympics 动物奥运会 Now, back to our regular stadium coverage. Dr. Michael Wilkinson still thinks Olympic runners would train better by kicking off their training shoes. He’s been running barefoot for six years, studying the performance and health benefits of running unshod. It’s not just more natural; Science Daily quoted him explaining, “There’s a difference between shod and barefoot running gaits that comes about from feeling the ground. The sensory feedback when running barefoot encourages runners to put their feet down more gently in an attempt to avoid the impact forces that would cause discomfort 7/7/2015 and are also linked to injury.” Need more reasons? 25 Animalympics 动物奥运会 In new research, Dr. Michael Wilkinson found that when runners who always wear shoes run barefoot they immediately alter their gait to that characteristic of habitual barefoot runners, and also use less oxygen during barefoot running compared to running with shoes at the same speed. This indicates greater running economy which is an important determinant of distance running performance, especially in elite runners. Habitual barefoot runners have a distinctive running gait — using mid-foot landings, shorter stride lengths, faster stride rates, and less time in contact with the ground. They are also known to hit the ground with lower impact force and loading rates than runners who land on the rear foot in trainers. This cushions the force of landing, avoiding the discomfort associated with striking the ground heel-first common in runners who wear shoes. 7/7/2015 26 Animalympics 动物奥运会 According to Wilkinson, barefoot running is a hot topic among physiologists and foot racers, but he warns against misinformation on some internet sites. With proper supervision, athletes new to barefoot running can quickly adapt and enjoy the benefits of those who habitually run barefoot, some of whom see a 3% to 6% performance boost. See the 1/27/2010 entry, “Barefoot is better.” 7/7/2015 27 Animalympics 动物奥运会 Look at us. We applaud our champions at the Olympics and carry on as if we inhabit this planet alone. We think we are so smart and fit, because we don’t spend enough time learning from our animal trainers – not humans who train animals, but animals who can train us, if we paid closer attention. For me, I’d like to learn how the guillemots do it. 7/7/2015 28 Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 Epigenetics refers to codes, processes and functions “above” genetics, that control and regulate the genetic code: a “code above the code,” as it were. Unlike a simple DNA strand, the epigenetic code has a multitude of players that scientists are still struggling to understand. For a good introduction, watch this 12-minute video on YouTube; for more depth, read the book The Mysterious Epigenome: What Lies Beyond DNA by Woodward and Gills (available from the C.S. Lewis Society and Amazon.com). One thing is becoming clear; DNA is just a bit player in a much vaster array of information. The big story now is what controls and regulates the DNA. Many things in the nucleus once considered “junk” are turning out to be the stars of the show. In addition, the findings are becoming more and more difficult to explain by neo-Darwinian mechanisms. Even more startling, 7/7/2015 29 epigenetics is undermining some key Darwinian principles. Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 Aging and epigenetics: Let’s begin with one close to home: aging. “Epigenomes of Newborns and Centenarians Differ: New Clues to Increasing Life Span,” announced Science Daily in bold red type, alongside a photo of a grandfather holding an infant. A new study shows defects due to mutations not just to genetic code base pairs, but to some of the epigenetic marks like methyl tags that help switch genes on and off. “The results show that the centenarian presents a distorted epigenome that has lost many switches (methyl chemical group), put in charge of inappropriate gene expression and, instead, turn off the switch of some protective genes.” Understanding these epigenomic processes will, obviously, be vital to improving the health and longevity of every human who gets 7/7/2015 30 older. Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 Micro-RNA regulators of regulators: Nature (June 28) reported that two enzymes “autoregulate” the production of micro-RNA’s (miRNA) which, in turn, regulate gene expression in many pathways (Zisoulis et al, Nature 486, pp. 541–544, doi:10.1038/nature11134). This discovery is “expanding the functions of the miRNA pathway in gene regulation,” they said. 7/7/2015 31 Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 Make space for the non-junk: “The myth of junk DNA” continues to get exposed. New Scientist reported that mouse “junk DNA” is vital for gene regulation. Hannah Krakauer’s opening sentence gives the gist of the article: “Some junk is worth keeping. Non-coding, or junk, mouse DNA contains vast amounts of information vital to gene function – and those regulatory functions take up much more space on the genome than the allimportant coding segments.” 7/7/2015 32 Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 Master regulator: PhysOrg’s article title summarizes the message: “Forty’s a crowd: Study shows that master regulator protein brings plethora of coactivators to gene expression sites.” After a discussion of a “behemoth” protein named Mediator, this paragraph was notable: Researchers know that all DNA-binding factors partner with other proteins to switch genes on or off. What is remarkable here is their sheer number. “It would be very interesting to find out whether this is the norm,” says Ron Conaway. “This work raises a ton of little questions about mechanism.” 7/7/2015 33 Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 Epigenetic disease: If diseases can be genetic in origin, so can it be egigenetic in origin. Science Daily wrote that epigenetics alters genes implicated in rheumatoid arthritis. “It’s not just our DNA that makes us susceptible to disease and influences its impact and outcome,” the article began. “Scientists are beginning to realize more and more that important changes in genes that are unrelated to changes in the DNA sequence itself — a field of study known as epigenetics — are equally influential.” 7/7/2015 34 Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 Epigenomes and cancer: One more example of the growing interest in epigenetics over plain old genetics is seen in an article in Science, “Genetic Events That Shape the Cancer Epigenome” by Ryan and Bernstein (Science, 22 June 2012: Vol. 336 no. 6088 pp. 1513–1514,DOI: 10.1126/science.1223730). Sure enough, “there is increasing recognition that transmissible epigenetic changes—chemical modifications to the genome or its scaffold that do not involve a change in the nucleotide sequence—may be acquired de novo, and that these “epimutations” may also contribute to carcinogenesis.” Scientists would not have understood this had they not looked above and beyond the genome into the epigenome. The Greek prefix “epi-” (above) appears poised 7/7/2015 35 to latch onto a number of old genetic vocabulary words. Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 Grammar and syntax, form and function: Remember the phrase, “The Human Genome”? It sounds almost quaint in hindsight. Not much more than a decade ago, scientists thought mapping the DNA letters would help us understand health, disease, and human evolution. The new term, according to Science Daily, is The Functional Genome – beyond mere basepairing. Starting with the mouse genome, scientists are trying to understand the paragraphs and superstructure within the genetic code, a language above the code itself. So far, they figure they only understand 11% of the mouse functional genome. Non-coding “cisregulatory elements,” for instance (once considered junk), regulate adjacent DNA, the article explained. 36 7/7/2015 Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 Popularly dubbed “the book of life,” the human genome is extraordinarily difficult to read. But without full knowledge of its grammar and syntax, the genome’s 2.9 billion base-pairs of adenine and thymine, cytosine and guanine provide limited insights into humanity’s underlying genetics.… As expected, the researchers identified different sequences that promote or start gene activity, enhance its activity and define where it occurs in the body during development. More surprising, said Ren, was that the structural organization of the cis-regulatory elements are grouped into discrete clusters corresponding to spatial domains. “It’s a case of form following function,” he said. “It makes sense.” 7/7/2015 37 Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 Good interference creates epigenetic memory: Why would some RNA transcripts interfere with others? It’s all part of a regulatory dance, scientists are finding out. Now, a new role for RNA interference (RNAi) was announced on PhysOrg: recognizing and silencing foreign DNA, such as strands introduced by viruses. It’s heritable, too: “Once identified, an ‘epigenetic memory’ of the foreign DNA fragments is created and can be passed on from one generation to the next, permanently silencing the gene.” This has an eerie echo of Lamarckian 38 7/7/2015 “inheritance of acquired characteristics.” Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 Once the DNA is identified as foreign and silenced, an epigenetic memory is created that silences the foreign gene from one generation to the next. While the inheritance of this memory requires further exploration, the authors showed that successive generations of C. elegans are unable to express the foreign DNA even if the corresponding piRNA is absent. 7/7/2015 39 Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 A vaster landscape: Geneticists used to speak of the “genetic landscape” but now there’s a vaster field: the “epigenetic landscape.” James Ferrell discussed this concept in his review, “Bistability, Bifurcations, and Waddington’s Epigenetic Landscape” in Current Biology (Volume 22, Issue 11, R458-R466, 5 June 2012), saying, “Waddington’s epigenetic landscape is probably the most famous and most powerful metaphor in developmental biology.” His rather lengthy review did not contain any of the following words: Darwin, phylogeny, evolution. 7/7/2015 40 Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 In the book The Mysterious Epigenome: What Lies Beyond DNA mentioned above, Woodward and Gills describe in verbal animation what it would be like to ride a sci-fi ship into the nucleus of a cell and watch gene regulation at work. Their second-to-last chapter, “An Infinitely More Complex Genome,” is like a 4th of July Grand Finale – a rapid-fire series of new discoveries and possibilities that portend a golden age of research in the years ahead, described in vivid metaphors like air traffic control, overlapping messages, codes here there and everywhere, and functional treasure in the “junk“ yard. 7/7/2015 41 Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 Two practical effects of the Epigenetic Revolution will be: (1) a realization that we are not slaves of our DNA, but that with healthy lifestyle changes, we can control the expression of genes (for instance, a vigorous workout at the gym makes observable effects on gene regulatory tags); (2) increasing pressure against Darwinism. The realization is growing that there is far more functional information in the cell than neoDarwinists ever imagined. If the genetic code was a challenge to explain by undirected processes operating stepwise by natural selection, what will be the reaction to codes upon codes, master regulators of other regulators, and millions of molecules performing 7/7/2015 42 a living symphony? Epigenetics: the 21st-Century Scientific Revolution 表观遗传学:21世纪科学革命 Got irreducible complexity? Here, Charlie. Come and look what we brought you: a little gift for your ailing stomach. Dr. Thomas Woodward,* a Christian theology professor, historian of science and president of the C. S. Lewis Society in Tampa, Florida, feels justifiably excited to see this vast new panorama of epigenetics as vindication par excellence for the Biblical world view. Not only that, he and co-author Dr. James P. Gills, a world-renowned ophthalmologist and modern pioneer of cataract surgery, see that world view in light of these discoveries contributing to human health: a new way to cultivate a spirit of wellness. This is not surprising, since Jesus said that a good tree produces good fruit (Matthew 7:17), and both ends of the Bible describe the Tree of Life that God 7/7/2015 43 planted. Psychologists Go Demonic 心理学家进入恶魔 Doctrines of demons: Clare Wilson at New Scientist reported on how psychologists at the University of British Columbia are using Ouija boards to probe the unconscious of experimental subjects. Many conservative theologians consider these devices to be devices for contacting deceiving spirits (I Timothy 4:1; see The Berean Call), and not a few non-theologians consider them dangerous (search Google on “ouija board dangerous”). Even if such theological views are deemed unscientific by secular psychologists, there is no question that these devices have an occult reputation: “Beloved of spiritualists and bored teenagers on a dare, the Ouija board has long been a source of entertainment, mystery and sometimes downright spookiness,” Wilson wrote44 7/7/2015 up front. Psychologists Go Demonic 心理学家进入恶魔 It’s not as if the psychologists are trying to debunk paranormal theories in their experiments. The psychologists employed the devices as probes of inner mental mysteries, believing in a Freudian doctrine that “the unconscious plays a role in cognitive functions we usually consider the preserve of the conscious mind.” One of them asked a question that borders on contact with the devil: “How can we communicate with that unconscious intelligence?” 7/7/2015 45 Psychologists Go Demonic 心理学家进入恶魔 The experimenter may not realize whose intelligence he is communicating with. According to Wilson, the results were a little spooky: “When using the computer, if the subjects said they didn’t know the answer to a question, they got it right about half the time, as would be expected by chance. But when using the Ouija, they got those questions right 65 per cent of the time — suggesting they had a subconscious inkling of the right answer and the Ouija allowed that hunch to be expressed.” (Note: the experimental subjects were blindfolded.) Maybe that’s why the URL to Wilson’s story asked, “is-there7/7/2015 46 anybody-there”. Psychologists Go Demonic 心理学家进入恶魔 Father of lies: Jesus spoke of Satan as a liar and the father of lies (John 8:44), the classic first lie starting in the garden (Genesis 3:4–5). All humans fall prey to bearing false witness at times, but it is especially egregious when scientists, ostensibly committed to intellectual integrity, follow the father of lies. Last year the fraud of Diederik Stapel “shook the field to its core” (see11/05/2011); now, another psychology fraud from the Netherlands was reported in Science magazine (6 July 2012: Vol. 337 no. 6090 pp. 21– 22), this time by a software algorithm devised by Uri Simonsohn to detect fraud. In the category “Scientific Ethics,” Martin Enserik headlined, “Fraud-Detection Tool Could Shake Up Psychology” because the ripple effect could affect more than just the career of latest perpetrator, 7/7/2015 47 Dirk Smeesters of Erasmus University Rotterdam: Psychologists Go Demonic 心理学家进入恶魔 The method may help the field of psychological science clean up its act and restore its credibility, he adds—but it may also turn colleagues into adversaries and destroy careers. The field will need ample debate on how to use it, Nosek says, much the way physicists had to grapple with the advent of nuclear physics. “This is psychology’s atomic bomb,” he says. Simonsohn already created a stir last year with a paper in Psychological Science showing that it’s “unacceptably easy” to prove almost anything using common ways to massage data and suggesting that a large proportion of papers in the field may be false positives. 7/7/2015 48 Psychologists Go Demonic 心理学家进入恶魔 While the validity of Simonsohn’s statistical tool is still being evaluated, Smeesters didn’t help matters much when he included in his explanation this cop-out: ” the odd data patterns found by Simonsohn emerged because of what he calls ‘questionable research practices’ that aren’t uncommon in his field, such as doing multiple analyses and picking the most convincing one, or leaving out certain subjects.” 7/7/2015 49 Psychologists Go Demonic 心理学家进入恶魔 Update 07/12/2012: Nature News reported another catch. Simonshohn found suspicious anomalies in the data of Lawrence Sanna, who retired inexplicably at the end of May from the University of Michigan at Ann Arbor, after requesting retraction of 3 of his papers. Again, Sanna’s data was too good to be true. Simonsohn had been questioning Sanna since fall, but the university would not explain the reason for his resignation, and Sanna is not responding to requests for information. Simonsohn denies being on a fishing expedition. ““Some people are concerned that this will damage psychology as a whole and the public will perceive an epidemic of fraud,” he said. Claiming that retractions are common in many fields, he said, “I think that’s unfounded.” He claims he’s just trying to set an 7/7/2015 50 example for how research data should be reported. Psychologists Go Demonic 心理学家进入恶魔 What is implied by the quote, “The method may help the field of psychological science clean up its act and restore its credibility”? Suppose, just for the sake of illustration, that Screwtape’s junior devil Wormwood decided to help out the experimental subject (“The Patient”) with the Ouija board and improve her score from chance to 65% correct. Wormwood, you realize, is a liar just like his mentor, Screwtape, and their master, “Our Father Below,” Satan. (To call these beings “deceiving spirits” would be a great compliment to them, from their point of view.) Knowing this background, let’s watch the dupe, the psychologist, perform his experiment, as we imagine 7/7/2015 51 the cackles of glee in the background. Psychologists Go Demonic 心理学家进入恶魔 The psychologist notices that the Patient is getting correct answers to a surprising number of questions she shouldn’t know. To alleviate any suspicions of trickery, he asks the Patient, “Am I communicating with your unconscious mind?” The blindfolded Patient moves the marker to the Yes mark on the board. “Is there any kind of outside influence acting on you right now?” Answer: No. “Do you believe in demons?” Answer: No. “Demons don’t exist, do they?” Answer: No. “Theologians are unscientific to believe in devils, aren’t they?” Answer: Yes. “Am I a good scientist?” Answer: Yes. “Should I write this up in a journal as experimental proof of the Unconscious?” Answer: Yes. “Are all my colleagues in psychology honorable and noble seekers of the 7/7/2015 52 truth?” Answer: Yes. Are You a Musical Animal? 你是一个音乐的动物吗? Music continues to be a distinctively human trait, despite evolutionists’ attempts to find its origin in mutation and natural selection. A new entry in the evolution-of-music genre is “What Makes Us Musical Animals” on Science Daily. The headline should have included a question mark, because no answer was forthcoming. All it could say was that researchers at the University of Amsterdam found two traits of musicality that are “conditional to the origin of music,” namely relative pitch (the ability to recognize a melody independent of its pitch) and beat induction (the ability to pick out a beat, even if it varies 7/7/2015 53 in tempo). Are You a Musical Animal? 你是一个音乐的动物吗? Necessary conditions, however, are not necessarily sufficient conditions. The Amsterdam band only tossed out these conditions as candidates: “Both relative pitch and beat induction are suggested as primary candidates for such cognitive traits, musical skills that are considered trivial by most humans, but that turn out to be quite special in the rest of the animal world,” the article said. Besides, the researchers did not explain where these traits came from. Mutations? The article admitted the difficulty of explaining music in evolutionary terms: 7/7/2015 54 Are You a Musical Animal? 你是一个音乐的动物吗? While it recently became quite popular to address the study of the origins of music from an evolutionary perspective, there is still little agreement on the idea that music is in fact an adaptation, that it influenced our survival, or that it made us sexually more attractive. Music appears to be of little use. It doesn’t quell our hunger, nor do we live a day longer because of it. So why argue that music is an adaptation? There are even researchers who claim that studying the evolution of cognition is virtually impossible (Lewontin, 1998; Bolhuis & Wynne, 2009). 7/7/2015 55 Are You a Musical Animal? 你是一个音乐的动物吗? So the Amsterdam band took a different tack: distinguish music from musicality. Despite their billboard on Science Daily, though, they still produced no music and no audience. Maybe, some day, they will put on a concert: “Once these fundamental cognitive mechanisms are identified, it becomes possible to see how these might have evolved,” the article ended. “In short: the study of the evolution of music cognition is conditional on a characterisation of the basic mechanisms that make up musicality.” 7/7/2015 56 Are You a Musical Animal? 你是一个音乐的动物吗? OK, time’s up. You evolutionists admitted back in 2008 that you had no clues (5/19/2008), and that your bandleader Charlie, who is all suit and no sound, all tux and no tune, all hand-waving but no harmony, was equally baffled by music 153 years ago. Yet here you remain, hogging the footlights, pretending to be the greatest show on earth. You are still not in the countdown, let alone the first measure. We asked back then, how much time should you get before admitting defeat? 7/7/2015 57 Are You a Musical Animal? 你是一个音乐的动物吗? You know that monkeys don’t have an ear for music (12/13/2004), but to humans, musicality is so innate, it’s trivial. After all this time, you still have nothing to say—nothing! Look at what you said in 2008, and here is the same refrain again: “Once these … mechanisms are identified…” Good grief. This is like saying, “Once we find some instruments and some charts in this pile of randomness, and find some animals who accidentally learn how to play the instruments and read music, then we’ll really have a show!” 7/7/2015 58 Are You a Musical Animal? 你是一个音乐的动物吗? You admitted back then, “Music’s origins have remained puzzling in the years since [Darwin], although there is no shortage of speculation on the subject.” You realize that science is not a perpetual license to make up stories. You’ve had your time, and it’s run out. Get off the stage and into the balcony. As imposters posing as scientists, you are hereby sentenced to listening to Handel’s Messiah till you repent. 7/7/2015 59 Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 According to widely accepted theory, planets evolve from orbiting dust disks surrounding stars. If so, planets trying to form in the dust around one young star didn’t have much time. The disk evaporated within 3 years. In “Astronomy: Warm dust makes a fast getaway” on Nature News, Margaret Moerchen summarized a paper by Melin et al., in Nature (“Rapid disappearance of a warm, dusty circumstellar disk,” 487 05 July 2012, pp. 74–76, doi:10.1038/nature11210) that is pretty shocking: “A rapid drop in infrared emission from a Sun-like star could indicate that a drastic event has cleared a circumstellar disk of dusty debris — the material from which planets form.” 7/7/2015 60 Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 Describing the “generally accepted” planetesimal hypothesis, Moerchen bluffed that “We know that such processes were involved in forming the architecture of the Solar System, as well as that of the ever-increasing number of planetary systems being discovered around stars other than the Sun,” but then confessed that “the precise timescales and conditions required for the formation of planets in the disks are still under investigation,” to put it mildly: there’s at least 4 to 6 orders of magnitude difference between expectations and observations here. “Notably, even for some disks in which the amount of dust present is considered likely to be transient and evolving rapidly, significant changes in that amount are expected to take at least thousands of 7/7/2015 61 years,” she said. Another put it into the millions. Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 None of the believers in the consensus planetesimal hypothesis expected to witness such a rapid change: reduction of infrared emission by a factor of 30 in 3 years, caused by, the astronomers believe, “a correspondingly drastic depletion of the dust disk” in short order. With characteristic understatement, Moerchen added, “the system in question is remarkable for the speed with which its surrounding material seems to have disappeared.” Where did it go? Why now? According to current theory, the star is 10 million years old. Why would it shed its dust disk right at the epoch when astronomers have the tools to 7/7/2015 62 watch it? Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 Nature News wouldn’t leave an embarrassing problem like this unresolved, would it? Moerchen offered some suggestions, but alas, confessed, “However, these hypotheses… can be excluded…” Then she offered the authors’ favored two solutions, but added, “However, both models have unresolved issues.” A couple of other solutions were put forth unenthusiastically, because they are catastrophic: the runaway accretion model, and the collisional cascade model, “in which gravitationally bound dust grains experience successive cratering or wholly destructive collisions that eventually yield grains small enough to be blown out of the system” – i.e., 7/7/2015 63 complete pulverization to smithereens. Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 That’s hardly conducive to planet formation, which is what the planetesimal hypothesis purports to explain. Moerchen ended with the best positive spin she could muster, commenting that “the extremely rapid changes in this dusty system are certain to provoke further discussion of planetarysystem evolution.” Indeed, the authors themselves confessed in their abstract, “Such a phase of rapid ejecta evolution has not been previously predicted or observed, and no currently available physical model satisfactorily explains the observations.” Her final paragraph is a model of theory-rescuing rhetoric in the face of evidential 7/7/2015 64 Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 The disappearance of the excess infrared radiation from TYC 8241 2652 1 in less than two years is incredibly fast by our current understanding, and the impact of this is difficult to predict. The dust-clearing models proposed by Melis et al. could be refined to bring them more into line with conventional theory. And theories that have been developed for other stars and that were adapted to TYC 8241 2652 1 could be redeveloped. However, perhaps the most exciting possibility is that the brightness drop represents a stage of terrestrial-planet formation that occurs so quickly that we have not been lucky enough to glimpse it 7/7/2015 65 until now. Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 How did the popular press report this anomaly? PhysOrg led off with the banal evolutionary formula, “New study sheds new light on planet formation.” The press release from University of Georgia featured home boy Inseok Song standing proudly by his telescope while the university’s spin machine turned the anomaly into a victory for evolution theory: “A study published in the July 5 edition of the journal Nature is challenging scientists’ understanding of planet formation, suggesting that planets might form much faster than previously thought or, alternatively, that stars harboring planets could be far more numerous.” Yes, that’s right: instead of millions of years, planets might form in a few! Think of the possibilities that “new light” allows: rapidly forming planets could now be much more common! The press release author seemed to take liberties with Song’s more humble interpretation of the unexpected 7/7/2015 66 finding: Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 “The most commonly accepted time scale for the removal of this much dust is in the hundreds of thousands of years, sometimes millions,” said study co-author Inseok Song, assistant professor of physics and astronomy in the UGA Franklin College of Arts and Sciences. “What we saw was far more rapid and has never been observed or even predicted. It tells us that we have a lot more to learn about planet formation.” 7/7/2015 67 Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 There were even appeals to magic. “Now you see it, now you don’t,” quipped lead author Carl Melin of UC San Diego, describing the classic magician’s line. “Only in this case we’re talking about enough dust to fill an inner solar system, and it really is gone.” (See before-and-after artwork in the PhysOrg coverage). Ben Zuckerman of UCLA added his own analogy: ““It’s as if you took a conventional picture of the planet Saturn today and then came back two years later and found that its rings had disappeared.” 7/7/2015 68 Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 Readers of the headline and not the fine print in the innards of the press release might miss this confession: “The researchers explored several different explanations for how such a large quantity of dust could disappear so rapidly, and each of their explanations challenges conventional thinking about planet formation… Like many important discoveries, the scientists’ finding raises more questions than it answers.” Song added that each one of the “uncomfortable” proposals to explain the phenomenon “has non-traditional implications.” Any answers are in the future: “my hope that this line of research can bring us closer to a true understanding 7/7/2015 69 of how planets form.” Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 Here’s a non-traditional proposal that was actually traditional before secular evolutionists reclassified it as non-traditional: stars and planets were created, and because of the laws of thermodynamics, they are breaking up, not building up. Unfortunately, Song’s chosen “line of research” will never take him there, because that route has been ruled out of bounds by a certain minority of human beings with a lot of power. 7/7/2015 70 Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 Well, isn’t this a fine situation we find science in today. We have “conventional thinking” that is dead wrong, findings that raise more questions than answers (as with “many important discoveries”), and non-traditional proposals that make people “uncomfortable”. Since when was comfort a requirement of truth? As they say, the truth hurts. 7/7/2015 71 Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 Suppose you had left your house to the care of a steward, and returned to find all your possessions gone. Would you laugh if he gave you a sheepish grin and said, “Now you see it, now you don’t”? After pressing him for answers, would you be satisfied if he tossed out some possibilities, but said each of them has “unresolved issues”? Suppose he said he had developed an answer, but could redevelop it. Suppose he tried to cheer you up by saying that the unexpected disappearance was “sure to provoke further discussion.” Suppose he tried to impress you with the “exciting possibility” that the spontaneous disappearance of the material was so quick, we were never lucky enough to glimpse it until now! No; if you were too gracious to fire him on the spot, you would certainly demand a credible answer and give him a time limit to produce it. 7/7/2015 72 Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 We entrust our scientists with the job of explaining the natural world. (Remember the big difference between scientific discovery and scientific explanation; it is noble to make these observations, but ignoble to maintain a false theory in the face of contradictory evidence by invoking ad hoc rescue devices that refuse to consider non-paradigmatic solutions, such as design). In any other line of business, a colossal failure of expectations of this magnitude would be grounds for dismissal. 7/7/2015 73 Stellar Dust Disk Vanishes in 3 Years 恒星的尘埃盘在3年内消失 Honor would require the failing steward to step up to the plate and say, “I was wrong; I failed; I will resign.” These losers, including their publicists, should at least forgo any taxpayer dollars designated for their failed analysis until and unless they demonstrate return on investment to those paying for their services. They can continue to observe and report findings, but if they want to engage in speculative theorizing with no obligation to get the world right, let them start a Flat Disk Society 7/7/2015 74 and do it on their own time and their own dime. Eats Shoots and Leaves 吃茎和叶 The latest human evolution star, Australopithecus sediba, ate leaves, according to its publicist, Lee Berger. In Nature News on July 5 (Margaret J. Schoeninger entertained the idea, giving credit to the star behind the star, the father of evolution: In 1871, Charles Darwin proposed that our earliest ancestors lived in Africa alongside the ancestors of today’s gorillas and chimpanzees, and ate a diet of fruit, leaves, seeds and nuts, similar to that of these extant primates. More recently, however, an alternative hypothesis has taken precedence — that the human lineage split from the apes in part as a result of our ancestors’ ability to obtain foods in open habitats, such as grasslands and savannah woodlands, that emerged in Africa following climatic changes during the Late Miocene epoch approximately 7 million years ago. 7/7/2015 75 Eats Shoots and Leaves 吃茎和叶 These foods included grasses, sedge plants, grass-eating insects and small animals. On page 90 of this issue,1 Henry et al. present evidence that our early relatives had a more diverse diet, and ate items such as fruits, leaves and bark. The findings will trigger a rethink of the selective pressures that resulted in the separation of the ape and human lineages, and the traits we now consider to be unique to each. 7/7/2015 76 Eats Shoots and Leaves 吃茎和叶 Any paleoanthropology discovery failing to “trigger a rethink” would break tradition (trigger? Remember, this is not a crime story). Berger gave Amanda Henry the limelight as first of 9 authors of the paper,1 but Au. sediba is his baby. Whether his baby ate leaves and bark from trees is less interesting to most readers as whether it belongs on the human family tree at all. Scheoninger barked about some of the uncertainty involving bigger issues than just 7/7/2015 77 diet: Eats Shoots and Leaves 吃茎和叶 The significance of these results extends beyond whether a diet based on C4 foods is a fundamental hominin trait. It also brings into question our understanding of the evolution of bipedalism — another trait that is thought of as being fundamentally human. The species in which bipedalism emerged, and the evolutionary pressures that drove this adaptation, remain topics of debate.… 7/7/2015 78 Eats Shoots and Leaves 吃茎和叶 How does the suggestion of dietary variation among hominins fit with this understanding of bipedalism and the branching of hominin species? Researchers have suggested that there was an adaptive radiation event approximately 2 million years ago, in which a common ancestor relatively rapidly gave rise to a range of bipedal species with novel traits that allowed them to move into new habitats. The unexamined assumption that all bipedal species share a unique genealogical relationship is reminiscent of evolutionary biologist Stephen J. Gould’s question: “What, if anything, is a zebra?”. Gould examined whether the three species of modern zebra are more closely related to one another than to other non-striped horse species. He concluded that striping evolved only once. We should also ask: what, if anything, is a hominin? 7/7/2015 79 Eats Shoots and Leaves 吃茎和叶 Perhaps all ancestral ape-like species that walked on two legs and had a C4–focused diet were uniquely related to each other but were not necessarily human ancestors. Maybe humans emerged from some other hominin groups around 2 million years ago that were also bipedal and had more general, opportunistic foraging strategies, including meateating. Only enterprising studies into other aspects of australopithecine and hominin life, like Henry and colleagues’ analysis of Au. sediba’s diet, will provide us with definitive answers. 7/7/2015 80 Eats Shoots and Leaves 吃茎和叶 Since definitive answers are lacking here, readers might like to look elsewhere. One place to look is Discovery Institute’s latest book, Science and Human Origins by Ann Gauger, Douglas Axe and Casey Luskin, announced June 20 on Evolution News & Views . A later post on ENV by David Klinghoffer described one chapter by Luskin that presents the appearance of the genus Homo as a “big bang” reminiscent of the Cambrian explosion. Postulating ape-like australopithecines to be human ancestors is “plagued with problems,” Luskin’s research survey revealed, a fact that the media “labor to obscure”. Particularly, Au. sediba presents evolutionary tree problems, Klinghoffer commented in another post on ENV: a diet of bark and leaves makes it less hominin-like and more ape-like than Berger wants. So if Au. sediba eats shoots, barks and leaves, is Berger barking up the wrong tree? 7/7/2015 81 Eats Shoots and Leaves 吃茎和叶 “Eats shoots and leaves” is a humorous phrase teachers use to point out the importance of punctuation to understanding (is it about a criminal or a koala?). But even if we take Berger’s meaning, it doesn’t mean he has understanding: especially if, after 141 years, Darwin’s tribe of forensic investigators still has to stuff their understanding in the pigeonhole labeled “things to do tomorrow.” We wonder what kind of “enterprising studies” Scheoninger has in mind. If history is any guide, the Darwinian form of “enterprising studies” belongs at Comedy Central, where they try to keep you laughing but never serve the beef; just empty promises that further studies will provide understanding. Shoot; 7/7/2015 82 make like a tree, and leaf for a real burger joint. Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 The cosmological inflation theory made Alan Guth famous back in 1981. In case the enthralled didn’t get the message, it was a colossal failure, Amanda Gefter broke the news on New Scientist. To set up Humpty Dumpty’s fall, she began with its seeming successes: “in one fell swoop,” it rescued big bang theory from the flatness problem and horizon problem. That was before cosmologists stopped admiring the “munificence” of inflation and starting thinking about its implications: it leads to 7/7/2015 83 nonsense: Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 The problem is that once inflation starts, it is nearly impossible to stop. Even in the tiny pre-inflation cosmos, quantum fluctuations ensured that the inflaton field had different energies in different places — a bit like a mountain having many balls balanced precariously at different heights. As each one starts rolling, it kicks off the inflation of a different region of space, which races away from the others at speeds above that of light. Because no influence may travel faster than light, these mini-universes become completely detached from one another. As the inflaton continues its headlong descent in each one, more and more bits of space begin to bud off to independent existences: 7/7/2015 an infinite “multiverse” of universes is formed… 84 Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 This is not good news for our hopes for cosmic enlightenment. In a single universe, an underlying theory of physics might offer a prediction for how flat the universe should be, say, or for the value of dark energy, the mysterious entity that seems to be driving an accelerated expansion of the universe. Astronomers could then go out and test that prediction against observations. 7/7/2015 85 Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 That’s not possible in an infinite multiverse: there are no definite predictions, only probabilities. Every conceivable value of dark energy or anything else will exist an infinite number of times among the infinite number of universes, and any universal theory of physics valid throughout the multiverse must reproduce all those values. That makes the odds of observing any particular value infinity divided by infinity: a nonsense that mathematicians call 7/7/2015 86 “undefined”. Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 Gefter quoted Max Tegmark of MIT who likened inflation theory to a charismatic guest who wore out his welcome and wouldn’t stop talking. It sounded so good at first. ““‘That would have been the perfect point for inflation to bow, wait for applause and exit stage left’,” says Tegmark. But that didn’t happen. Instead, inflation kept on predicting still more things — things that nobody wanted.” Tegmark and others now agree inflation theory died: 7/7/2015 87 Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 “We thought that inflation predicted a smooth, flat universe,” says Paul Steinhardt of Princeton University, a pioneer of inflation who has become a vocal detractor. “Instead, it predicts every possibility an infinite number of times. We’re back to square one.” Tegmark agrees: “Inflation has destroyed itself. It logically self-destructed.” Sean Carroll was only a little less pessimistic. ““Inflation is still the dominant paradigm,” he said, “but we’ve become a lot less convinced that it’s obviously true.” By starting with such precisely balanced conditions, it explains less than the flukes it was intended to explain. ““If you pick a universe out of a hat, it’s not going to be one that 7/7/2015 88 starts with inflation,” he said. Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 Brane Drain Gefter took a brief tour into other cosmological theories that arose to replace inflation, such as brane theory: two 4-D projections of 5-D surfaces collided at perfect parallels, yielding a big-bang lookalike. One benefit for those uncomfortable with a cosmic beginning is that it resurrects old hopes of a cyclic universe with an infinite past. Any theory, though, that tries to explain special conditions (e.g., our universe) with even more special conditions fails to show the kind of scientific progress cosmologists prefer–simple beginnings leading to complex observations, a “theory of everything.” Thus, a “brane drain,” as Gefter 7/7/2015 89 Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 If nothing else, the cyclic model introduced some competition into the big bang market. “It shows that you’re not stuck with inflation — other ideas are possible,” says Steinhardt. “But whether or not you like this particular alternative is a matter of taste.” Not everyone did. Models of the big bang that involve a singularity in our space-time, including the inflationary big bang, neatly excuse us from explaining what happened at the universe’s beginning: the singularity is a place where the universe falls off the cliff of existence and the laws of physics break down. But in the cyclic model, we must explain how the fifth dimension survives its 7/7/2015 90 momentary lapse into a singularity. Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 “To me, it doesn’t seem to work,” says Thomas Hertog of the Catholic University of Leuven (KUL) in Belgium, who worked on the idea for a couple of years. “The calculations suggest that the transition through the singularity is very unlikely.” The many clashes between branes that the model implies just compound the problem, says Carroll. “If you follow the cyclic universe backward in time, the conditions that you need become more and more special, or unlikely.” 7/7/2015 91 Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 No Boundaries Next came the “No-Boundary Proposal” of Stephen Hawking and James Hartle, made famous in the former’s best seller, A Brief History of Time. Gefter described it as a kind of “multiverse in reverse,” where Hawking and Hartle “added up all the possible histories that began in a universe with no boundary and ended in the universe we see today.” Though some were initially attracted to the proposal because it seemed to get rid of a beginning to the universe, it hardly merited a couple of paragraphs in Gefter’s review: “That all sounds very neat, but there was still no reason to believe the noboundary proposal was true. It was difficult to see where it fitted in to the sort of unifying theoretical constructs, such as string theory, which are needed to explain events in the early, high-energy days of the universe.” 7/7/2015 92 Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 Cosmic Combo Plate Nothing seemed to work. How about a combination? Gefter tried to end on a cheerful note by suggesting that maybe a combination of inflation, string theory, the no-boundary proposal might serve up a universe that solves the problems inflation tried to solve without making things worse. Adding bad ideas together might seem another bad idea. There had to be at least one new trial ingredient, and string theory served up the spaghetti: 7/7/2015 93 Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 That might just have changed, thanks to one of the most profound ideas to come out of string theory in recent years: the holographic principle. This states that the physics of a 4D universe such as ours, including gravity, is mathematically equivalent to the physics on its 3D boundary without gravity. The implication is that the world we see around us is nothing but a holographic projection of information from the edge of reality. It sounds implausible, but the principle pops up not just in string theory, but in almost any approach to unifying relativity 7/7/2015 94 and quantum theory dreamed up so far. Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 If this sounds bizarre, remember that in modern cosmology, bizarre is beautiful as long as it gets rid of intelligent design. It may also sound like a stretch of desperation. To Gefter and her cosmology protagonists, the Holographic Principle comes to the rescue of the NoBoundary Proposal, string theory and inflation in the nick of time. One weird aspect of the idea she explained: 7/7/2015 95 Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 Although the no-boundary proposal says that the universe has no boundary in the far past, it does give a boundary in the infinitely far future. By calculating the physics on this boundary, Hertog extracted the probabilities of all the possible universes that can emerge as its holographic projections. Remarkably, the probabilities for things like the homogeneity of the cosmic background or the amount of dark energy are the same as those that you get from the no-boundary wave function. This supplies a direct connection between string theory, the most popular route towards a theory of everything, and the no-boundary proposal, which produces inflation naturally. “Originally the no-boundary wave function was sort of picked out of thin air,” says Hertog. “But now we see that it lies at the heart of the holographic principle. This is very 7/7/2015 96 encouraging for inflation.” Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 Cosmologists are still “digesting” the combo plate, Gefter ended. Some are “questioning whether the assumptions it makes are justified.” Even Alan Guth, whose inflation theory the new proposal rescues somewhat, is not sure about the validity of its specific holographic correspondence, but is willing to give researchers time to play with it. Gefter decked the halls of the holodeck with bows of jolly, hoping the Holographic Principle may bring back the doubters, like Tegmark, who consider inflation an imposter. “We are not yet there, at the true story of the beginning of the universe,” she ended. If we can consistently apply quantum mechanics to the fabric of the universe, we might get there. “Only then will we truly know what kind of a bang the big bang was.” At least secular cosmologists are in complete agreement on 3 things: the universe exists today, it originated in the 7/7/2015 97 past, and the explanation is in the future. Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 Cosmologist: a highly intelligent person, very gifted in mathematics, who devotes his life to rationalizing insane ideas. If you think this is harsh, remember what Prophet Berman said 8 years ago? (10/06/2004). Modern cosmologists are clueless, they’re right out of The Emperor’s New Clothes, and nothing they say is likely to be true. For further proof, look at how their biggest ideas have all been undermined. They are like white tourists in Fiji trying to do firewalking. They dance from one hot rock to another in a kind of Brownian motion, grinning for a few milliseconds on each one 7/7/2015 98 before the pain is unbearable. Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 Learn an important lesson here. Cosmologists and the press leapt onto inflation like flies to a carcass, so excited that the brilliant genius Alan Guth (Grand Unified Theory Huckster) saved the big bang from the Flatness Problem and the Horizon Problem. “In one fell swoop,” Gefter reminded us, he saved the day. Inflation was simple. It was elegant. It was beautiful. It was wrong. Tegmark likened it to the gift that keeps on giving till it got sickening, or like the performer that should have bowed out but kept giving encores nobody wanted, to the point they ran out of the theater screaming. 7/7/2015 99 Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 So they retreated to other irrationalities, like brane theory or the no-boundary proposal. As with inflation, brane theory turned out to create more problems than it explained: it required even finer tuning than the fine-tuned universe we see. As for Hawking & Hartle’s Hilarious Hoopla (4H) that proposed a no-beginning in a no-time fantasyland, remember it was a proposal, not a theory (proposal, n.:the act of offering or suggesting something for acceptance, adoption, or performance). It was a suggestion they offered, like “try this.” That’s not even a hypothesis yet. 7/7/2015 100 Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 So now, it’s back to inflation, with a combo plate of no boundaries, strings and The Holodeck. We’re all like Lt. Commander Data wandering in an imaginary Holographic universe that is a projection of something real we cannot be sure is really there. As usual with everything evolutionary, the answer is all futureware and promissory notes. Why does anybody listen to these people? It doesn’t matter if they can write equations all over the blackboard. If the inputs to a “proposal” are bogus, no amount of mathematical manipulation can rescue a lie. 7/7/2015 101 Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 If you really want to see what’s motivating these folks, look at a slide show by Max Tegmark from a symposium, reproduced on Scribd. The wiggle room in cosmology would make a mouse in a boxcar feel crowded. Tegmark reasons himself into a multiverse with the flimsiest of arguments, all while struggling to defend his naturalism against the clear implications of our low-entropy universe. “Sound too crazy?” one slide asks in large yellow print on a black background. (This means he knows it’s crazy.) But his justification for his craziness is seen on the very next slide: it’s a portrait of Charles Darwin, with the caption, “We’re not taking this guy seriously enough.” What, you ask, has Darwin to do with a multiverse? Ah, you see, this is all part of the Religion of the Bearded Buddha: try to explain everything from the bottom up without that despised, dreaded Designer. Anything but that!– 7/7/2015 102 even irrationality. Inflation Again: This Time with Feeling 再次膨胀:这一次有感觉 We would direct your attention back a few slides in Tegmark’s show to a photograph of a group of sharplooking college students wearing black T-shirts with redand-white lettering. Tegmark knows all about the symbols in white: those are Maxwell’s Equations, a set of four equations that James Clerk Maxwell, a Christian and creationist, derived to explain all electromagnetic phenomena. The caption in red letters reads, “And God said,” [Maxwell’s Equations], “and there was light.” (See similar design close up here.) We invite these highly intelligent but misguided individuals, lost in the dark, to come to the light. It’s so much easier to work with proper lighting; much more 7/7/2015 103 satisfying, too. Are Two Cambrian Explosions Better than One? 两个寒武纪爆炸,比一个好? Science Daily just picked up on a press release from Oxford University that came out two weeks ago: the discovery of exquisitely-preserved Ediacaran creatures. Both articles explained that the Ediacaran fauna appear to bear no relationship to the Cambrian animals that came (in Darwin years) millions of years later, even though “where exactly they fit in the tree of life is unclear.” The discoverers believe the animals are baby rangeomorphs, animals with frond-like structures that “lived deep beneath the ocean where there would have been no light.” 7/7/2015 104 Are Two Cambrian Explosions Better than One? 两个寒武纪爆炸,比一个好? That’s where their explanation for the burial seems puzzling: “A volcanic eruption around 579 million years ago buried a ‘nursery’ of the earliest-known animals under a Pompeii-like deluge of ash, preserving them as fossils in rocks in Newfoundland, new research suggests.” Lest one think this was an undersea volcano, Professor Martin Brasier clarified it: 7/7/2015 105 Are Two Cambrian Explosions Better than One? 两个寒武纪爆炸,比一个好? ‘We think that, around 579 million years ago, an underwater ‘nursery’ of baby Ediacaran fronds was overwhelmed, Pompeii-style, by an ash fall from a volcanic eruption on a nearby island that smothered and preserved them for posterity.’ By all accounts, the inhabitants of Pompeii that were buried by the ash fall from Mt. Vesuvius did not live at the bottom of the sea. One would think the ash would float, get diluted or be swept around by currents, not fall to this spot at the sea 7/7/2015 floor where the animals were living at the time.106 Are Two Cambrian Explosions Better than One? 两个寒武纪爆炸,比一个好? It’s also not clear how the professors were able to spin the story into a blessing for Darwin. “The discovery confirms a remarkable variety of rangeomorph fossil forms so early in their evolutionary history,” the article said. Professor Brasier added another difficulty to the fact that they appeared in a remarkable variety out of nowhere: their diversification came “in an ‘Ediacaran explosion’ that may have mirrored the profusion of new life forms we see in the Cambrian.” 7/7/2015 107 Are Two Cambrian Explosions Better than One? 两个寒武纪爆炸,比一个好? When you look in a mirror, you usually see an image of yourself. How the Ediacaran fauna could have mirrored the Cambrian, when there was no relationship between the creatures, is strange, unless it is like you looking through a clear glass at a tree and you both explode at the same time. Apparently this is what the eminent Professor professes: the Ediacaran explosion was just as rapid, and produced as many pieces of debris, as you and the tree. 7/7/2015 108 Are Two Cambrian Explosions Better than One? 两个寒武纪爆炸,比一个好? This story is more proof that anything goes in Evolutionary Fantasyland, as long as Darwin gets the gory glory. Maybe one should ask, instead, why scientists keep finding so many examples in the fossil record of abrupt appearance of complex life, rapid burial, and exquisite preservation. What’s “evolutionary history” got to do with it? 7/7/2015 109 Arsenic Life Isn’t 不是砷的生命 Remember the claim in 2010 that living organisms were discovered using arsenic instead of phosphate? Further tests show it was not the case. The announcement of alien life on our own planet captivated the media briefly in December 2010 (see “Arsenic and Old Lake, 12/02/2010). This week, though, PhysOrg, National Geographic,Live Science and Astrobiology Magazine were among news outlets announcing Felisa Wolf-Simon’s claim was wrong. If true, it “would have revolutionized how we think about life,” NASA’s Astrobiology Magazine noted, but two subsequent studies have apparently confirmed that the organism does require phosphate, not arsenic, in its genetic code. This undercuts the main claim of “arsenic7/7/2015 110 based life.” Arsenic Life Isn’t 不是砷的生命 National Geographic said the life-form named GFAJ-1 (after Felisa’s initials) does not represent a “second Genesis” of life on Earth. Astrobiologist Paul Davies, however, contends that one falsification does not invalidate his quest to continue looking for alien life on our own planet. Wolf-Simon is not conceding, though. She thinks that if the organism ingests tiny amounts of arsenic, it will still validate her claim. Most of the other scientists looking into it say she will have to provide much stronger evidence. 7/7/2015 111 Arsenic Life Isn’t 不是砷的生命 Isn’t this a good example of science at work? Doesn’t this show that science is a selfcorrecting process, like the late positivist Carl Sagan emphasized? Aren’t scientists showing themselves to be unbiased truth-seekers, willing to debunk an idea even if they prefer it were true, if the facts do not confirm it? Aren’t they setting a good example of intellectual integrity? 7/7/2015 112 Arsenic Life Isn’t 不是砷的生命 Well, nes and yo (those are inextricable mixtures of yes and no). Sure; to a degree they have illustrated a desire for strong evidence in this instance. But this one was easy. The organisms are right here on our home planet, easily collected and studied in the lab (easy compared to studying life on Europa or some extrasolar planet). They still believe in evolution despite 153 years of falsifying evidence since Darwin published his storybook. Take a look at this quote from the PhysOrg article: “NASA has conducted numerous probes at eastern California’s Mono Lake, an unusually salty body of water with high arsenic and mineral levels, as it is likely to reflect conditions under which early life evolved on Earth, 7/7/2015 113 or perhaps Mars.” Arsenic Life Isn’t 不是砷的生命 With silly evidence-free tales like that, contrary to all we know about probability and the complexity of life, their brief escapade into integrity is too little too late. Evolutionists are still straining out a bacterium and swallowing a camel. They pay their tithes of mint, phosphate and arsenic but ignore the weightier issues of the law of nature, that design demands a Designer. They remain blind leaders of the blind on the really big questions. OK, so here’s 2 cents for your honesty here, but pay up on your trillion-dollar promissory notes that expired 152 years ago. 7/7/2015 114 Volcano Tour Planned 火山旅游计划 A key researcher of the catastrophic geology at Mt. St. Helens is leading hikes on the volcano next month. Dr. Steve Austin, well known creation geologist whose studies have taken him to Alaska, Grand Canyon, Argentina and Israel, spent years studying the rapid geologic processes that were evident after the 1980 eruption of Mt. St. Helens. He even did scuba dives to the bottom of Spirit Lake to study the vertical emplacement of trees on the bottom, and discovered a 1/40 scale Grand Canyon cut in a day by a mudflow. He also found where fine and coarse laminations in a cliff were deposited in days, not in tens of thousands of years. 7/7/2015 115 Volcano Tour Planned 火山旅游计划 Dr. Austin will be returning to the volcano August 3–4 to lead two instructional hikes for those interested. Since most visitors cannot get permits for the areas on the tour, this is a rare opportunity to gain hands-on understanding of volcanology with a field geologist who was influential in reviving catastrophism in geology, and has inspired many to rethink the secular geological timescale. The hikes are expected to be vigorous, so a certain level of physical fitness is required. 7/7/2015 116 Maple to the Rescue 枫叶救援 The SWAT team surrounds the compound. An officer tosses a maple seed into an open window and checks the readout on his computer. The team bursts in and, surprising the terrorists, rescues the hostages safely. 7/7/2015 117 Maple to the Rescue 枫叶救援 This scenario may become a reality, thanks to a new flying robot called Samarai, fashioned after the winged “samara” shape of the maple seed. A high-energy video clip at Live Science tells the story of a tiny drone developed by Lockheed Martin for the military. Engineers analyzed the shape of the seed’s wing and studied its flight dynamics. Then they outfitted a plastic replica with a motor and a camera to create their miniature surveillance tool. 7/7/2015 118 Maple to the Rescue 枫叶救援 Like a maple seed, Samarai has the advantage of very stable flight. It can be launched from the floor, by a flick of the wrist, or from an elevated platform. A remote control allows the operator to make it rise or turn in an any direction, or hover indefinitely. (See “Introducing the Maple Copter,” 10/21/2009.) One problem was how to produce images on a spinning camera. The team developed software that can take out the blur and stitch together the frames into a normal wide-angle 7/7/2015 119 motion picture, providing a stable 360° image. Maple to the Rescue 枫叶救援 This would allow our imaginary SWAT team to see inside the building to pinpoint the location of the terrorists and hostages. The military would love to have these on the battlefield for reconnaissance. Some day Samarias could be standard equipment for law enforcement, search and rescue, and other applications – thanks to the common, humble, ordinary maple seed. 7/7/2015 120 Maple to the Rescue 枫叶救援 If it ever comes to the day when government snoops on citizens this way, be sure to have a strong fly swatter handy. More likely, this will be one of the coolest toys for Christmas sometime. Lawyers will undoubtedly find new opportunities to go after people spying on their neighbors. Wise parents, though, will take their kids into the forest with their toy, let them enjoy it for awhile, then show them that the Creator designed it first. The Creator even devised a way to stabilize an image from a moving 7/7/2015 121 platform. Anxiety May Shorten Your Cell Life 焦虑可能会缩短你的细胞寿命 Two newly published studies involving thousands of nurses show that lifestyle and attitude might influence the age of your cells. Telomeres are special “end caps” on chromosomes that keep them from unwinding. Cells begin with a number of caps; each time a cell divides, a cap is lost (although the telomerase enzyme can add new telomeres). Much remains to be learned about telomeres, but they seem to be implicated with aging. When a chromosome runs out of telomeres, it can no longer divide, and the cell 122 7/7/2015 dies. Anxiety May Shorten Your Cell Life 焦虑可能会缩短你的细胞寿命 Can lifestyle and attitude influence telomeres? This is largely unknown territory. Starting in 1976, thousands of female nurses participated in a Nurses Health Study (NHS) by filling out questionnaires on their health habits and anxiety levels and following up every 2–3 years. In 1988–1990, thousands submitting blood samples. This data has now been correlated with telomere counts in the leukocytes (white blood cells), important cells in the immune system. 7/7/2015 123 Anxiety May Shorten Your Cell Life 焦虑可能会缩短你的细胞寿命 One study by Qi Sun et. al, published in May in PLoS ONE, found a correlation between telomere shortness and unhealthy lifestyles. Another study by Okereke et al., just published July 11 in PLoS ONE, found a possible connection between “phobic anxiety” and telomere shortness. This study was summarized on Science Daily. 7/7/2015 124 Anxiety May Shorten Your Cell Life 焦虑可能会缩短你的细胞寿命 The authors of these papers realize that correlation is not causation, and even correlation is difficult to measure, due to errors and omissions such as inconsistencies in questionnaire responses, lack of follow-up blood samples, evaluation of a single cell type, and evaluations of one gender only. Nevertheless, the researchers found statistically significant correlations that remained stable even after cross-checking their data various ways. These studies had the advantage of large data sets involving thousands of participants. 7/7/2015 125 Anxiety May Shorten Your Cell Life 焦虑可能会缩短你的细胞寿命 If the correlations remain robust in similar studies, it would indicate that mental states and lifestyle choices can produce epigenetic effects on our genes. Most of us realize that poor lifestyle choices and anxieties are unhealthy, but these studies suggest a detailed physical connection between mind and body about which many of us were unaware. 7/7/2015 126 Anxiety May Shorten Your Cell Life 焦虑可能会缩短你的细胞寿命 Since it’s very difficult to have high confidence in correlation studies like this, we’ll mark this as interesting and potentially valuable to know. It fits well with what biologists are learning about the “mysterious epigenome” (see 07/04/2012 entry). Wouldn’t it be something if your fears or choices have a tangible effect on the action of the telomerase enzymes in your cells? Don’t make your telomerase say, “What’s the use? My owner doesn’t care about all the work I do.” 7/7/2015 127 Ingenious Seed Bomb “Designed by Evolution” “进化设计”巧妙的种子炸弹 Red hot peppers! Can evolution “design” anything, especially a chemical bomb a plant uses to be sure its seeds get spread properly? There’s a desert plant in the Middle East that has an ingenious way of dispersing its seeds. Many plants rely on animals for help, but there’s a problem: the animal helper needs to spread the seed without destroying it. For instance, many plants surround their seeds by fleshy, delicious fruits, but if the animal munches the seeds, there they go, into oblivion 7/7/2015 128 instead of into the soil. Ingenious Seed Bomb “Designed by Evolution” “进化设计”巧妙的种子炸弹 Current Biology tells the story of Ochradenus baccatus (“Taily Weed”; see photo in Flowers of Israel), a homely desert shrub that has a “mustard oil bomb” method of attracting animals but protecting its seeds from getting eaten. It attracts rodents with the delicious fruit, but if they bite into the seeds, a chemical reaction occurs between the fruit juice and the seed juice, and pow! a distasteful, toxic mustard oil bomb goes off in the mouth. The rodents quickly learn to spit out the seeds rather than eat them. Fortunately for the plant, the rodents (to avoid getting eaten by their own predators), take the fruits to their rocky habitats, the best places for the seeds to grow. This provides an especially tight example of commensal mutualism, where both parties benefit equally 7/7/2015 129 from their interaction. Ingenious Seed Bomb “Designed by Evolution” “进化设计”巧妙的种子炸弹 In the Current Biology review article, K. C. Burns (U. of Wellington) did his best to evolutionize the story while admiring the designs of the plant world. First, he plagiarized the title of a well known book by Darwin champion Richard Dawkins, headlining his article, “Seed Dispersal: The Blind BombMaker.” In the attempt, though, he personified evolution too often, starting right in the first paragraph: 7/7/2015 130 Ingenious Seed Bomb “Designed by Evolution” “进化设计”巧妙的种子炸弹 Seed dispersal sets the stage for everything that happens to a plant during its lifetime — after germination, plants will never again be able to travel across the landscape. Seeds can’t move very far on their own, though, so they rely on wind, water or animals to get the job done. For example, coconuts float on water to reach their destination. Maple seeds fly through the air using auto-rotating wings that operate similarly to helicopter blades. Dandelion seeds use feathery plumes that function like parachutes. Another common mechanism of seed dispersal is to enlist 7/7/2015 131 the help of animals. Ingenious Seed Bomb “Designed by Evolution” “进化设计”巧妙的种子炸弹 Many plants surround their seeds with fleshy pulp to strike up mutualistic partnerships with fruitconsuming animals, who swallow seeds whole and defecate them intact in new locations. Animalassisted seed dispersal can be a highly effective means of seed transportation, but it is often fraught with difficulty. In a new study in this issue of Current Biology, Samuni-Blank et al. demonstrate that a desert plant has taken an ingenious step towards solving the problems associated with animal-mediated seed dispersal. 7/7/2015 132 Ingenious Seed Bomb “Designed by Evolution” “进化设计”巧妙的种子炸弹 Presumably, evolution taught problem-solving skills to the plant. The plant’s difficulty is simultaneously attracting partners and resisting predators. Well, red hot peppers! Chilis found a way, he said: they sneak capsaicin into the fleshy fruit. In mammals (except for some masochistic humans), the capsaicin sets the mouth on fire and sends the eater running for the cold water faucet. Birds, which are not affected by capsaicin, eat the fruit with the seeds and defecate them unharmed elsewhere via air mail, but rodents learn to leave the chilis alone. 7/7/2015 133 Ingenious Seed Bomb “Designed by Evolution” “进化设计”巧妙的种子炸弹 Did you know your summer picnics are part of this symbiotic interplay? We can relate to the rodents’ plight. Watermelons (Citrullus lanatus) are filled with large seeds, and most of us spit them out before swallowing the juicy pulp, largely because the seeds have a sour taste. This sour taste is our bodies’ way of telling us that the seeds are defended chemically. By listening to our taste buds and spitting the seeds out, we avoid investing the energy to metabolise these defensive chemicals and avoid any harmful effect they might have after ingestion. However, in the case of O. baccatus, it is the combination of chemicals stored separately in the fruit pulp and in the seeds that creates the chemical 7/7/2015 134 deterrent, not just the seeds themselves. Ingenious Seed Bomb “Designed by Evolution” “进化设计”巧妙的种子炸弹 Here’s where Burns mixed his metaphors. He reminded us that human engineers have designed bombs that don’t detonate till two components mix, but then attributed a similar “design” to the unguided processes of evolution. He first presented the “evolutionary conundrum” for plants needing seed dispersers without attracting seed predators. He claimed that the Taily Weed and rodent “co-evolved” their mutualistic dance of seed dispersal and feeding. And then in the case of the chili pepper, he said, “capsaicin triggers receptors located in mammalian mouths that have been designed by evolution to respond to excessive heat.” Burns never quite bothered to explain how the complex secondary metabolites in the fruit (glucosinolates) and the enzyme (myrosinase) in the seeds that detonates the “mustard oil bomb” evolved by mutation and natural selection in the first place, let alone the complex heat 7/7/2015 135 receptors in the mammalian mouth. Ingenious Seed Bomb “Designed by Evolution” “进化设计”巧妙的种子炸弹 It’s noteworthy that the main paper Burns was summarizing said nothing about evolution (Samuni-Blank et al., “Intraspecific Directed Deterrence by the Mustard Oil Bomb in a Desert Plant,” Current Biology, Volume 22, Issue 13, 1218–1220, 14 June 2012, 10.1016/j.cub.2012.04.051). In fact, it begins with a 4-minute video narrated cheerfully by lead author Michal Samuni-Blank (Israel Institute of Technology), who describes, without mentioning evolution once, how her team discovered and tested the “directed deterrence hypothesis” with 7/7/2015 136 chemical analysis and good old field work. Ingenious Seed Bomb “Designed by Evolution” “进化设计”巧妙的种子炸弹 Let’s have some fun with the phrase, “evolutionary conundrum” (pretending, for the moment, that it is not redundant). So: Wonders of design happen whenever Evolution, the fairy godmother (identified as Tinker Bell), waves her mutation wand with no goal or purpose in mind. Our mouth receptors were Designed by Evolution to respond to excessive heat, we just learned. The capsaicin, on the other hand, was Designed by Evolution to turn these receptors on and signal, “Fire in the hole!” But then, the brains of weird people were Designed by Evolution to fan the flames and make chilis part of their fine cuisine. The plant was therefore Designed by Evolution to get these weird people to cultivate even more chilis so that they would spread their 7/7/2015 137 selfish genes even further. Ingenious Seed Bomb “Designed by Evolution” “进化设计”巧妙的种子炸弹 Watermelon seeds, by contrast, were Designed by Evolution to make humans spit them out. Humans, in response, were Designed by Evolution to create watermelon seed spitting contests (or was that Evolution designing the watermelon to make the humans do this?). Evolution designed humans to retaliate by designing seedless watermelons. (This is known as an evolutionary arms race.) But if Evolution is such a good Designer, why didn’t Tinker Bell find the mutation to design watermelons with delicious seeds that pass through the human digestive tract? Oh, we get it; it’s because Evolution designed the human to design toilets and sewer systems, so the seeds would never make it to the soil. But the watermelon has the last laugh, because Evolution designed the human to realize that without propagation by other means than seeds, their favored watermelons would138go 7/7/2015 extinct. Ingenious Seed Bomb “Designed by Evolution” “进化设计”巧妙的种子炸弹 It must be fun to be an evolutionist. All you need is imagination, and imagination has no limits. To them, evolutionary imagination is like capsaicin. Most of us run for the cold water of observable science, but to them, imagination is delicious. They have lost all feeling. The fiery heat of imagination is normal; the more the better! 7/7/2015 139 Ingenious Seed Bomb “Designed by Evolution” “进化设计”巧妙的种子炸弹 For a great 100% Darwin-free documentary on seed dispersal, see the Moody Video Journey of Life (also incorporated as Volume 1 of Wonders of God’s Creation). You’ll see the examples Burns mentioned and many others: coconut, dandelion, maple seed, and many more – illustrations of little living miracles all around us that can enrich our lives just to learn about. 7/7/2015 140 Our Poisonous Moon: Better from a Distance 我们有毒的月亮:离远更好 The moon stabilizes Earth’s axis and regulates the tides, but enjoy it from a distance. Now there are more reasons you wouldn’t want to live there. “Long-term human exposure to the lunar environment has never been studied in depth, and it’s quite possible that — in addition to the many inherent dangers of living and working in space –the Moon itself may be toxic to humans,” wrote Jason Major wrote at Universe Today(emphasis in original). He was reporting on a paper produced by an international team of physiologists, pharmacologists, radiologists and toxicologists from 5 countries, who sought to quantify the dangers to humans of extended 7/7/2015 141 Our Poisonous Moon: Better from a Distance 我们有毒的月亮:离远更好 In the ArXiv paper by Linnarson et al., “Toxicity of Lunar Dust,” (open access), the researchers attempted to fill the “knowledge gaps” about health hazards in lunar dust while recognizing that “ground truth” on actual effects will require in situ measurements. According to Major’s summary, the risks include inhalation of fine dust, skin damage and eye damage. 7/7/2015 142 Our Poisonous Moon: Better from a Distance 我们有毒的月亮:离远更好 Lunar dust is not subject to the erosional processes on Earth, so the particles tend to have sharp edges. These can be compared to “pollutants encountered on Earth, such as asbestos and volcanic ash,” Major said; “lunar dust particles are small enough to penetrate deep within lung tissues, and may be made even more dangerous by their long-term exposure to proton and UV radiation.” In addition, the microgravity environment of the moon may loft these particles around the 7/7/2015 143 airways. Our Poisonous Moon: Better from a Distance 我们有毒的月亮:离远更好 The dust is dangerous on the outside, too. Apollo astronauts noticed that the dust clings to everything. Long-term exposure to the sharp-edged particles, even in the safety of a lunar base, could cause skin abrasions, particularly on the fingers, knuckles, elbows and knees. And if the dust were to irritate or scratch the cornea of the eye, would there be an opththalmologist in the base to prevent blindness? 7/7/2015 144 Our Poisonous Moon: Better from a Distance 我们有毒的月亮:离远更好 These were just a few of the risks of extended lunar habitation. Some of the fine particles might enter tissue cells, or activate the immune system. They might release free radicals into tissues and organs. Even if the dust problems could be overcome, the moon remains unprotected from solar UV radiation, the solar wind, solar flares, micrometeorites and highenergy cosmic rays. 7/7/2015 145 Our Poisonous Moon: Better from a Distance 我们有毒的月亮:离远更好 The authors listed 34 remaining “knowledge gaps” about lunar toxicity. If any of these (many suspected to be high to very high risk) were to prove serious, it might cause a reconsideration of the wisdom of sending humans to the moon for extended stays. Since some of the risks apply to Mars as well (and since the moon would probably be a training base), these findings could put a damper on hopes for manned missions to Mars. 7/7/2015 146 Our Poisonous Moon: Better from a Distance 我们有毒的月亮:离远更好 God’s green Earth is starting to look quite nice, isn’t it? Maybe you’re fretting the heat, the rain, the wind, or the cold. After a week on the moon, you would count the days to get back home. There are hazards on Earth, too, but at least you can breathe the air, get dirty in the garden and shower it off, and usually live out a lifetime without the constant protection of an artificial bubble. 7/7/2015 147 Our Poisonous Moon: Better from a Distance 我们有毒的月亮:离远更好 Consider that the moon is almost exactly at the same distance from the sun as Earth. That’s why all the astrobiological optimism about extrasolar planets within habitable zones is mostly hype. The moon is in the perfect habitable zone, too! Many other factors are required to make a body habitable. Time to watch The Privileged Planet again and count your lucky star.* *The word lucky used here loosely to include Providence. 7/7/2015 148 Birdifying Dinosaurs 变成鸟的恐龙 Birds and dinosaurs have oval eggs and big eyes. Does this necessarily mean they evolved from a common ancestor? Hopeful ovals: Intent on evolving sparrows out of T. rex kin, some paleontologists are selectively basing arguments for common ancestry on similarities that do not seem all that impressive. For instance, a report on PhysOrg allowed researchers from Barcelona to claim common ancestry based on oval egg shape. “Researchers from Spain identified in Lleida a series of dinosaur eggs with a unique characteristic: They are oval in shape,” the subtitle announced. “The discovery represents proof in favor of the hypothesis that birds and non avian theropods, dinosaurs from the Cretaceous Period, could have a common ancestor.” The reporter later downgraded from proof to the milder phrase that it “suggests a connection with bird eggs.” If such a shape had been found in an unrelated animal group’s eggs, Darwinists would have undoubtedly attributed it to 7/7/2015 149 “convergent evolution.” Birdifying Dinosaurs 变成鸟的恐龙 Peter Pan evolution: Nature on July 12 declared that “Birds have paedomorphic dinosaur skulls” (paedomorphic referring to “retaining a morphology as adults that resembles that of the juveniles or embryos of most other archosaurs”). The team of Bullar et al. (Nature 487, 12 July 2012, pp. 223–226, doi:10.1038/nature11146) performed detailed measurements of skulls of birds and theropods, and hypothesized that bird skulls represent a stage of arrested development of dinosaur skulls. Are they implying that a dinosaur didn’t finish maturing, and became a bird instead? Apparently so, and don’t think for a minute that we humans are exempt from this kind of hypothesis. They added, “Heterochrony—change in the timing or rate of developmental events—has been implicated in the evolution of major vertebrate lineages such as mammals, 7/7/2015 150 including humans.” Birdifying Dinosaurs 变成鸟的恐龙 They didn’t even try to hide their evolutionary dogmatism. The first sentence begins, “Birds are living theropod dinosaurs”. Yet they recognized the uniqueness of birds, too: “The unique bird skull houses two highly specialized systems: the sophisticated visual and neuromuscular coordination system allows flight coordination and exploitation of diverse visual landscapes, and the astonishing variations of the beak enable a wide range of avian lifestyles.” Still, they stuck to their story that “the heterochronic process of paedomorphosis, by which descendants resemble the juveniles of their ancestors, is responsible for several major evolutionary transitions in the origin of birds,” counting at least four episodes of arrested development (except for bird beaks, 7/7/2015 151 which advanced beyond dinosaur developmental stages). Birdifying Dinosaurs 变成鸟的恐龙 They boasted that “Evidence for heterochrony is clear.” The array of skull diagrams, phylogenetic trees and other scientific apparati seem convincing. Yet to believe their hypothesis requires, first, accepting common ancestry as a given, and second, rejecting prior evolutionary theory: “Strong support for a progenetic paedomorphic origin of the bird skull seemingly contradicts early work suggesting that simple paedomorphosis in the form of having ‘retained a juvenile shape’ was not involved in the origin of the bird skeleton” – i.e., the rest of the body below the skull does not show heterochrony. It would indeed seem strange if the skull stopped developing while the rest of the body went on to maturity. 7/7/2015 152 Birdifying Dinosaurs 变成鸟的恐龙 But that’s what they suggested, tossing those hot potatoes to the references: “Cranial evolution is modular with respect to the rest of the body and it is not unusual to find divergent rates of transformation between crania and postcrania, for instance in the origins of pterodactyloid pterosaurs19and the origin of mammals20, 21.” Not only that, they have to explain why the beak and brain proceeded well beyond whatever evolution had cooked up for the long reign of the dinosaurs. “In addition, birds do not have embryonic brains,” they confessed. 7/7/2015 153 Birdifying Dinosaurs 变成鸟的恐龙 To explain this, they came up with a novel idea for evolution: “The brain emerges in this analysis as a major driver of theropod cranial anatomy.” Isn’t that the responsibility of mutation and natural selection? Calling the brain a driver smirks of intelligent design, as if the evolving theropod was planning out the rest of its skeleton. Surely that is not what they meant. To remain consistent with neo-Darwinism, it would have to mean that brain mutations at random resulted in all the specializations enjoyed by birds: their wings, unique flight muscles, avian lungs, and modifications to every physiological system. From there, the rest of the paper collapsed into complete speculation with a series of maybes, perhapses, 7/7/2015 154 suggestions and imaginary possibilities: Birdifying Dinosaurs 变成鸟的恐龙 Cranial transformations driven by optic elaboration during the origin of birds parallel olfactory elaboration during mammalian origins23. The brain is an early signalling centre during facial development25 and it is possible that the posteroventral rotation of the brain is in part responsible for the collapse of the facial region in birds. Archaeopteryx–like elaboration of visually associated brain regions also appears in Eumaniraptora and may be correlated with some degree of volancy26 [i.e., gliding or flying]. Although it has been suggested that reduction in body size, which we show accompanied heterochronic transformation I, was associated with the advent of dinosaurian flight16, our results agree with work suggesting that size 7/7/2015 155 18 reduction preceded powered flight . Birdifying Dinosaurs 变成鸟的恐龙 This reduction may, however, have been a necessary precursor to flight exapted [i.e., function not acquired by natural selection] in its service. The origin of flight was a multistep process and it remains unclear precisely when volancy and powered flight respectively originated18. Finally, the peramorphic enlargement of the premaxilla to form a long, pointed beak is coupled with progressive loss of manual grasping ability as digits became bound into the wing27. Modern birds are known to perform fine manipulations with the precision tips of their beaks28. It may be that the beak evolved in part as a replacement for the eponymous raptorial hands of maniraptoran dinosaurs. In short, ascribing a few similarities in skull shape to heterochrony as an explanation for the origin of birds from 156 7/7/2015 Birdifying Dinosaurs 变成鸟的恐龙 The desire to force data into evolutionary stories is overpowering to Darwin disciples. It has come to the point where they are willing to deploy the fallacy of suggestion recklessly to support their belief. Look how many times they used it in that one paragraph above. The sprinkling of observational data is a distraction. Remember when 19th century evolutionists meticulously measured skulls to support their racial biases? Evolutionists need to explain much, much more than minor changes to skull shape to make their case. The carelessness of their hypothesis is also seen in its selective application: the eyes evolved by heterochrony, but the beak and postcranial skeleton are the opposite–they are peramorphic (advanced beyond the adult stage). That’s a convenient dodge that makes no sense unless you start and end with assuming evolution. If we were to apply their method as recklessly as they do, we could claim (since humans exhibit heterochrony, too), that our noses are heterochronic 7/7/2015 157 elephant trunks, but our femurs are peramorphic dog legs. Birdifying Dinosaurs 变成鸟的恐龙 Evolution is a gimmick where data are only props to support a belief. You can pick props at will; use the ones that support the belief, discard the ones that don’t. When you can’t avoid the obvious, toss your hot potatoes (difficult questions and anomalies) to other evolutionists by referring to their papers in your references. The times we have checked those references, we find those evolutionists doing the same thing: making bold claims by the power of suggestion with little data to support it, then tossing their hot potatoes to the next guy in line. It’s like a large circle of evolutionists tossing their hot potatoes round and round, never holding onto one long enough to show they can take the heat of serious objections. Another trick is the futureware excuse: offer a suggestion and promise that confirmation will come with further study. It gives the illusion of progress. But that’s all it is—an illusion. If you need proof, look at how evolutionists have been using this gimmick for over 150 years since Darwin taught them how to get away with it, yet they still have major unanswered questions about the evolution of anything and 158 7/7/2015 everything. Birdifying Dinosaurs 变成鸟的恐龙 Don’t confuse precision measurement of skulls with scientific progress. Evolutionists need to explain every complex life form by an unguided, purposeless process of mistakes. Evolution is NOT PROGRESSIVE. Progress implies a goal, an end point, a purpose, a plan. Natural selection is not progressive. There is no selector! That is the personification fallacy. A selector implies purpose, choice, plan, a goal. The adaptability of living things is evidence of design, not evolution. Why? Because evolution, being pointless and aimless, is a restatement of the Stuff Happens Law – whatever happened, happened. That’s an abdication of scientific explanation. It’s a gimmick masquerading as science. When you remove the assumption of evolution, their research, their papers, their work collapse into a pile of nonexplanations. The assumption is the superstructure that holds 7/7/2015 159 the house of cards together. Venter: Life Is Robotic Software 文特尔:生命是机器人软件 What is life? It’s software that runs biological robots, says a leading geneticist. In 1943, before the genetic revolution, physicist Erwin Schrödinger spoke at Trinity College (Dublin, Ireland) on the subject, “What Is Life?” It was unusual for a physicist to address a biological subject. Approaching life in physical terms, Schrödinger realized that life needs to store information. By its nature, biological information has to be aperiodic (i.e., non-repeating) yet stable, like a crystal. This led him to ponder the possible future discovery of an aperiodic, crystalline “genetic code” as a conveyor of biological information. 7/7/2015 160 Venter: Life Is Robotic Software 文特尔:生命是机器人软件 Schrödinger’s prescient insight occurred before the computer revolution, and a decade before Watson and Crick’s elucidation of the structure of DNA. It not only inspired many to view life through a physical lens, it also encouraged more physicists and chemists to ask biological questions. Those questions presaged the discovery of an actual genetic code written in DNA, on informational macromolecules. As we know, that discovery led to a genetic revolution that has continued unabated to the present day of genetic engineering. 7/7/2015 161 Venter: Life Is Robotic Software 文特尔:生命是机器人软件 Claire O’Connell used this background for her report in New Scientist on the current meetings at Trinity that are ending today (July 15). In Schrödinger’s footsteps, Craig Venter took the stage at Trinity to discuss the same question, “What Is Life?” O’Connell sees this as “passing the baton” from one influential scientist to another; Venter’s name will be familiar to many, not only as the entrepreneur who raced the US government’s Human Genome Project to the finish line, but as the charismatic TED showman who has wowed large audiences by boasting his team’s successful creation of the first synthetic cell whose parents are a computer. (Actually, Venter plagiarized 7/7/2015 162 existing life; see 5/22/2010 and 6/2/2010). Venter: Life Is Robotic Software 文特尔:生命是机器人软件 Venter’s description at the meeting underscores how far we have come in our conception of the nature of life. A brief history: for centuries, life was seen as fundamentally different from non-life. The synthesis of urea in 1828 by Wöhler was a first bombshell to old thinking; scientists began to see an overlap between organic chemistry and regular chemistry. That line of thought remained productive till Schrödinger, Watson and Crick revealed another special trait of biological chemistry: it is a conveyer of information. Venter’s statement this week now brings together physics, chemistry, information 7/7/2015 163 science and robotics: Venter: Life Is Robotic Software 文特尔:生命是机器人软件 “All living cells that we know of on this planet are ‘DNA software’-driven biological machines comprised of hundreds of thousands of protein robots, coded for by the DNA, that carry out precise functions,” said Venter. “We are now using computer software to design new DNA software.” The digital and biological worlds are becoming interchangeable, he added, describing how scientists now simply send each other the information to make DIY biological material rather than sending the material itself. 7/7/2015 164 Venter: Life Is Robotic Software 文特尔:生命是机器人软件 Venter speaks freely these days about DNA software, genetic design, and digital life. His team even programmed text messages into their synthetic cell. To emphasize the informational nature of DNA as software, O’Connell pointed out that human-designed DNA software even has bugs: But perhaps the most intriguing anecdote Venter shared was his description of how his team ‘watermarked’ their synthesised DNA with coded quotations from James Joyce, Robert Oppenheimer and Richard Feynman, only to learn that they had included a mistake in the Feynman quote. Venter’s rather airy description of how they just went back in and fixed it drove home just how far we’ve come in being able to understand, and even manipulate, our own DNA molecules. James Watson, now 84, was present at Venter’s speech and shared the applause with Venter. 7/7/2015 165 Venter: Life Is Robotic Software 文特尔:生命是机器人软件 Secular scientists are apparently viewing this as a victory for materialism, but it’s actually the opposite. Information is not material. This is clear from the fact that the same information can be conveyed by a blackboard, an email, skywriting or voice. There’s a growing realization that Information must be added to particles and forces as a fundamental entity needed to describe the universe. 7/7/2015 166 Venter: Life Is Robotic Software 文特尔:生命是机器人软件 The very fact that we can take the DNA code and program it with a computer shows that its essence is software – a form of complex specified information. Our human experience with software, codes and messages makes it the most rational inference that software-driven biological machines operating protein robots have an intelligent cause. This should be the death of materialism, actually. Combining these discoveries with the principle of conservation of information (i.e., that information cannot exceed its source, and degrades without intelligent proofreading and maintenance), the evidence now more strongly than ever implies that biological information has an intelligent cause greater 7/7/2015 167 than the effects we observe. Venter: Life Is Robotic Software 文特尔:生命是机器人软件 Those who wish to take the next step beyond science in the direction the evidence points can locate that intelligence in God. “By faith,” the author of Hebrews said, “we understand that the universe was created by the word of God, so that what is seen was not made out of things that are visible.” Look how modern that statement sounds. The universe was created by the word of God (information, communication), so that what is seen (material) was not made out of things that are visible. In short, the invisible information came first by the Word (logos, as in John 1:1), then the 7/7/2015 168 material.* Venter: Life Is Robotic Software 文特尔:生命是机器人软件 Also noteworthy in Claire O’Connell’s story was that it never mentioned evolution. Darwin is disappearing stage left as Venter, Watson and a new generation of information engineers rise to the footlights, describing life as fundamentally information-rich software. They may still be materialists, but they cannot justify materialism by their own science. As materialism dies, so will its ground of relativism and amorality. Before tinkering with the biological software, then, man with his limited knowledge and questionable wisdom had better rethink his accountability to the 7/7/2015 169 omniscient and all-wise Creator. Venter: Life Is Robotic Software 文特尔:生命是机器人软件 *Footnote: O’Connell’s statement about biologists sending each other the information instead of the biological material itself suggests, for Christians, an interesting possibility about the resurrection. Skeptics have scoffed at the idea of the resurrection of the dead. The biological material of a human body quickly degrades. What if a man is eaten by a shark, which is caught and eaten by a fisherman? Whose body will be raised? It’s possible your body contains the atoms of countless dead people that have been recycled through the food chain. 7/7/2015 170 Venter: Life Is Robotic Software 文特尔:生命是机器人软件 But if the essence of the body is software, not its material substance, it is simply a matter of reconstructing the atoms from the code – analogous to how technicians can rebuild a company’s computer center at an offsite location on new hardware with backup tapes. Venter stated in his TED talk that a third of all humanity’s DNA genomes would fit on the proverbial head of a pin. For the Biblical Creator who called life into existence by His Logos, it’s no problem at all to resurrect every person’s physical body right out of the spot where it died, assembling the atoms from the code and upgrading it to Body 2.0 on the way up. 7/7/2015 171 Boat Men or Float Men 小船人或浮动人 Alleged human ancestors may have drifted to islands without boats, an evolutionist claims. “Hominins did not need boats to settle island,” wrote Jeff Hecht at New Scientist. He was thinking about the ancestors of The Hobbit, Homo floresiensis. But the suggestion of “hominins” drifting out to sea on flotsam to islands without planning to do so could extend to true humans like Neanderthals, too, even though they had access to boats 100,000 years ago in the evolutionary timeline. “The new finding suggests that in both cases the hominins could have reached the islands without boats.” How exactly? – “hominins may have arrived as castaways, carried172 7/7/2015 Boat Men or Float Men 小船人或浮动人 Lest readers find the hypothesis of two guys from UK hopelessly implausible, Hecht reminded them that other evolutionists have suggested that’s how rats got to the islands of Indonesia. Small elephants might have swum across the channel. The short article did not refer to any examples in recorded history of castaways floating on debris from floods or tsunamis and landing on islands, ready to start building a new civilization. 7/7/2015 173 Boat Men or Float Men 小船人或浮动人 One problem with the idea is getting enough fertile couples to arrive simultaneously to establish a stable population. You need about five young couples to get a population going for 500 years. Robinson Crusoe was a dead end, in other words; so was the Swiss Family Robinson. To overcome the problem, the two guys from UK suggested “throwing in between one and four additional castaways every 50 years” to increase the odds. 7/7/2015 174 Boat Men or Float Men 小船人或浮动人 Evolutionary anthropologists sure don’t give our ancestors much credit. If Neanderthals didn’t learn from the last castaways to stay out of the storm, they deserved the Darwin Award for vacationing by accident on the Isle of Debris. Actually, if those members of Homo were like the ones we know, they would have established shipping lanes for a lively seafaring trade with the islanders in short order – no tens or hundreds of thousands of years required, no need to throw in more castaways every 50 years. Exercise: count the weasel words in the article: may have, suggests, could have, etc. 7/7/2015 175 Body Double: Your Body as a Template for Inventors 双体:你的身体作为一个发明家的模板 Your body contains a lot of things engineers would like to copy, and not just at the scale of C3P0-like humanoid robots. Pore over this: Your cell membranes have pores that let good things pass through but block the rest. One of the most important is the ion channel, responsible for passing electrical signals in the nervous system. The extreme selectivity of these pores, some of which can pass potassium ions but block sodium ions, is desirable to chemical engineers, but difficult to achieve in synthetic materials. “Inspired by nature,” a press release from the University at Buffalo began, “an international research team has created synthetic pores that mimic the activity of cellular ion channels, which play a vital role in human health by severely restricting the types of materials allowed 7/7/2015 176 to enter cells.” Body Double: Your Body as a Template for Inventors 双体:你的身体作为一个发明家的模板 The team’s synthetic pores are pretty crude by cellular standards. They are just stacks of nanotube rings at this stage; achieving high selectivity is a future goal. But the lead researcher is hopeful: “The idea for this research originated from the biological world, from our hope to mimic biological structures, and we were thrilled by the results.” 7/7/2015 177 Body Double: Your Body as a Template for Inventors 双体:你的身体作为一个发明家的模板 Home sweet homeostasis: The body’s ability to maintain stability in a dynamic world (homeostasis) requires control and regulation at many levels. Wouldn’t it be nice if chemists could do something like that in the lab? A Harvard team publishing in Nature thought so: Living organisms have unique homeostatic abilities, maintaining tight control of their local environment through interconversions of chemical and mechanical energy and self-regulating feedback loops organized hierarchically across many length scales. In contrast, most synthetic materials are incapable of continuous self-monitoring and self-regulating behaviour owing to their limited single-directional chemomechanical or mechanochemical modes. 7/7/2015 178 Body Double: Your Body as a Template for Inventors 双体:你的身体作为一个发明家的模板 Applying the concept of homeostasis to the design of autonomous materials would have substantial impacts in areas ranging from medical implants that help stabilize bodily functions to ‘smart’ materials that regulate energy usage. (from the abstract of Ximin He et al, “Synthetic homeostatic materials with chemo-mechano-chemical selfregulation,” Nature 487, 12 July 2012, pp. 214–218, doi:10.1038/nature11223) 7/7/2015 179 Body Double: Your Body as a Template for Inventors 双体:你的身体作为一个发明家的模板 The team put together a bilayer gel that was able to maintain one parameter— temperature—within a narrow range. Crude, but it’s a start, and it gave something for the people at Harvard’s Wyss Institute for Biologically Inspired Engineering to aim for. 7/7/2015 180 Body Double: Your Body as a Template for Inventors 双体:你的身体作为一个发明家的模板 Shedding tears over clogged ink-jet printers: Tired of paying for ink cartridges for that old ink-jet printer? Part of the cost is waste. Because the ink in the nozzle dries after last use, fresh ink has to blast through a crust of dry ink each time. Engineers at the University of Missouri took a cue from the human eye and made a breakthrough with a new clog-free nozzle. How did they do it? They shed tears over the nozzle, in the form of silicone oil, that keeps the nozzle moist just like tears keep the cornea moist so that your eyelids don’t stick shut when you close your eyes. 7/7/2015 181 Body Double: Your Body as a Template for Inventors 双体:你的身体作为一个发明家的模板 “The nozzle cover we invented was inspired by the human eye,” said Jae Wan Kwon, associate professor in the College of Engineering. “The eye and an ink jet nozzle have a common problem: they must not be allowed to dry while, simultaneously, they must open. We used biomimicry, the imitation of nature, to solve human problems.” The engineers at Mizzou think that this simple trick inspired by the blink of an eye can save businesses thousands of dollars.

Let Kermit show the way. “Frog calls inspire a new algorithm for wireless networks,” reported PhysOrg. Male Japanese tree frogs know a trick called “desynchronization,” i.e., not sending their calls at the same time, to avoid confusing the female. Researchers at the Polytechnic University of Catalonia took this cue to discover an algorithm for coloring network nodes that prevents any two adjacent nodes from having the same color, while minimizing the number of colors. “This study falls under the field of ‘swarm intelligence’, a branch of artificial intelligence that aims to design intelligent systems with multiple agents,” the article explained, showing how the idea can be extended to other situations. “This is inspired by the collective behaviour of animal societies such as ant colonies, flocks of birds, shoals 7/7/2015 183 of fish and frogs, as in this case.” Body Double: Your Body as a Template for Inventors 双体:你的身体作为一个发明家的模板 Lizard rover: With the new Mars Curiosity rover about to land in a couple of weeks (see landing video), engineers are thinking ahead to the next generation of rovers. As we all know, it’s easy for cars to sink in sand and get stuck, and running or walking across sand takes more energy. Lizards, though, scamper across the sand like a walk in the park. According to Michael Slezak at New Scientist, the Georgia Tech bioengineers have bested the UC Berkeley team in the robotic sand-run competition. They did it by imitating lizards instead of UCB’s cockroach model (note: cockroaches do not normally run on sand, but lizards do). The Georgia Tech team studied slow-motion video of lizard footsteps and found that lizardlike legs and their speed of travel makes the sand behave more like a fluid that the lizard can push off of without sinking in. With memories of the multimillion-dollar Spirit rover stuck in Martian sand, rover designers are undoubtedly paying attention. Maybe some day earthbound adventurers, too, can benefit, with a new184 7/7/2015 feature on their 4WD sports vehicles: retractable lizard feet. Body Double: Your Body as a Template for Inventors 双体:你的身体作为一个发明家的模板 Here is more cutting edge, Darwin-free science and engineering that is helping humanity. Darwinian storytelling is becoming like smoking. In decades past, almost everyone in the science lab smoked, and nobody worried about it. Then, non-smokers meekly requested smoke-free environments. Companies gradually began obliging by designating areas for non-smokers. Still, the smoke drifted into the nostrils of those offended. 7/7/2015 185 Body Double: Your Body as a Template for Inventors 双体:你的身体作为一个发明家的模板 Simultaneously, the public was becoming more aware of scientific discoveries about the dangers of cigarette smoke. Soon, non-smoking areas became the default, and smokers found themselves having to go outside to designated smoking areas, as smoking became prohibited in more and more public areas. Warning labels became more prominent and cigarette taxes rose. Today, smokers still engage in their dirty habit, but they are increasingly frowned upon in polite society, while managers look askance at smoking breaks as non-productive use of time. 7/7/2015 186 Body Double: Your Body as a Template for Inventors 双体:你的身体作为一个发明家的模板 Darwin storytelling is like smoke in the biomimetics lab. It’s still taken for granted, and everyone is used to the smell, but over time, it may be increasingly viewed as useless, even harmful. We shouldn’t outlaw storytelling, but should issue warning labels: “Warning: this scientific explanation contains neo-Darwinism, which is hazardous to societal health” (11/30/2005). It would be gracious of the Darwinists to voluntarily take their filthy habit outside of the scientific journals into designated storytelling areas, provided they keep it to themselves and don’t try to influence the young. The upcoming generations of scientists, enjoying the invigorating fresh air of bio-inspiration, need to maintain 7/7/2015 187 their health for the good of us all. Scientific Ignorance Becomes Apparent 科学的无知变得明显 Two reports indicate that what we know we don’t know vastly exceeds what we think we know. Isaac Newton once said of his monumental scientific work, “I was like a boy playing on the sea-shore, and diverting myself now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.” Some scientists today err on the pride side, using the oft-repeated phrase “Now we know” this or that. Two recent reports prefer Newton’s assessment. 7/7/2015 188 Scientific Ignorance Becomes Apparent 科学的无知变得明显 What creatures inhabit our planet? There are billions of people on this globe, living almost everywhere, even in Antarctica. Humans have driven submarines to the deepest ocean trenches, and sampled the upper atmosphere. They have sampled every portion of every continent. One would think they’ve seen everything by now. Not so; in an article entitled, “What We Know and Don’t Know About Earth’s Missing Biodiversity,” Science Daily said, 7/7/2015 189 Scientific Ignorance Becomes Apparent 科学的无知变得明显 Most of the world’s species are still unknown to science although many researchers grappled to address the question of how many species there are on Earth over the recent decades. Estimates of non-microbial diversity on Earth provided by researchers range from 2 million to over 50 million species, with great uncertainties in numbers of insects, fungi, nematodes, and deep-sea organisms. 7/7/2015 190 Scientific Ignorance Becomes Apparent 科学的无知变得明显 …and that’s just living species. The fossil record hints of far greater biodiversity in the past, multiplying our ignorance about life on Earth. When we don’t know what is alive today, we can’t know what medicines they might be able to provide (consider, for example, that penicillin was discovered in a fungus). One researcher remarked, “The problem is how one protects an animal that has never been seen.” 7/7/2015 191 Scientific Ignorance Becomes Apparent 科学的无知变得明显 What makes the cosmos work? We’ve reported several times that most cosmologists believe that 95% of the universe is composed mysterious, unknown stuff called dark matter and dark energy. But that’s just the unseen unknowns. More profoundly, most of the stuff shining right into our telescopes remains unknown. Another Science Daily article explained, 7/7/2015 192 Scientific Ignorance Becomes Apparent 科学的无知变得明显 Our day-to-day lives exist in what physicists would call an electrically neutral environment. Desks, books, chairs and bodies don’t generally carry electricity and they don’t stick to magnets. But life on Earth is substantially different from, well, almost everywhere else. Beyond Earth’s protective atmosphere and extending all the way through interplanetary space, electrified particles dominate the scene. Indeed,99% of the universe is made of this electrified gas, 7/7/2015 193 known as plasma. Scientific Ignorance Becomes Apparent 科学的无知变得明显 This implies that most of what science busies itself with represents 1% of visible reality. Astronomers certainly know about electromagnetic forces, but except for those working in a few specialized fields (such as stellar and planetary magnetospheres), they are wont to talk about the atoms, subatomic particles and gravity (i.e., the other three fundamental forces) of stars and galaxies, ignoring the electromagnetic properties of plasma that are possibly more critical to explaining their nature. Many questions remain about the plasma of our local star, the sun, and the electrical 7/7/2015 194 environment around our own planet Earth: Scientific Ignorance Becomes Apparent 科学的无知变得明显 Scientists want to understand not only the origins of electrified particles — possibly from the solar wind constantly streaming off the sun; possibly from an area of Earth’s own outer atmosphere, the ionosphere — but also what mechanisms gives the particles their extreme speed and energy. 7/7/2015 195 Scientific Ignorance Becomes Apparent 科学的无知变得明显 The universe at large, however, is filled with extremely energetic processes like supernovae, gamma ray bursts, and black holes, where plasma predominates. A new NASA mission called Radiation Belt Storm Probes (RBSP) to be launched in August will try to answer some of the local questions described in the Science Daily article. It’s only a stepping stone to that great ocean of truth that lays undiscovered before us: 7/7/2015 196 Scientific Ignorance Becomes Apparent 科学的无知变得明显 While the most immediate practical need for studying the radiation belts is to understand the space weather system near Earth and to protect humans and precious electronics in space from geomagnetic storms, there is another reason scientists are interested in this area. It is the closest place to study the material, plasma, that pervades the entire universe. Understanding this environment so foreign to our own is crucial to understanding the make up of every star and galaxy in outer space. Embedded within that paragraph is an admission of how little is understood by scientists today about that foreign environment that makes up 99% of visible 7/7/2015 197 reality. Scientific Ignorance Becomes Apparent 科学的无知变得明显 Speaking about that leftover 1%, how much of that is really understood? Consider how much remains to be explained about epigenetics, archaeology, health and medicine, cell biology, geology, paleontology – you name it – every field of science within our non-representative, electrically-neutral bubble is riddled with further questions. Then consider the time dimension, both past and future: we have limited access to our past, and no “scientific” access to the future except for educated guesses based on induction (a philosophically vexed kind of logic). Pile on top of that our complete ignorance of the “unknown unknowns” and the “unknowable unknowns” (see Evolution News & Views). It is easy to conclude that scientists know very little at all. 7/7/2015 198 Scientific Ignorance Becomes Apparent 科学的无知变得明显 Scientists discover many things that are useful for the present. In terms of understanding reality, though, science is a pacifier that grants false assurance that everything is OK. Those big people behind the glass have things under control. Now suck on your pacifier and stop worrying about it. 7/7/2015 199 Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 Tie “survival of the fittest” to “larger brains are more fit” and what do you get? The horrors of 20th century social Darwinism are well documented. Ideas have consequences. Giving power-hungry leaders two principles that, when mixed together, justify their wildest ambitions in the name of science, is like giving bomb ingredients to a terrorist – only on a much more massive scale. Those two ideas are: (1) might makes right, because nature has determined that only the fittest survive, and (2) some brains are more fit than other brains. Need we detail the racial atrocities, genocides and wars that exploded from that toxic blend? 7/7/2015 200 Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 A recent article in Nature News, had a title that should raise eyebrows: “Mostly the big-brained survive.” It suggests that the toxic ideas themselves survive, even if under the surface in an innocent article about conservation. Emma Marris wrote like a caring conservationist concerned about the welfare of endangered species. But she expressed social Darwinian ideas as if oblivious to what happened in the 20th century: “Large-brained animals may be less likely to go extinct in a changing world, perhaps because they can use their greater intelligence to adapt their behaviour to new conditions,” she wrote; “.…a bigger brain–to-body7/7/2015 201 size ratio usually means a smarter animal.” Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 Although Marris did not use the word fitness or the phrase “survival of the fittest,” the idea was implicit in the notion that smarter animals are less likely to go extinct. A corollary is that nature favors the smarter animal. Marris and Eric Abelson (Stanford U), whose research she highlighted, were discussing brain size of mammals in general. A picture of a cute tarsier adorns the article. To their credit, they included several points that could exonerate them from any allegations of social Darwinism. For one, they were not talking about humans specifically at all. Secondly, they pointed out the disadvantages of the big-brained: 7/7/2015 202 Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 For species larger than about 10 kilograms, the advantage of having a large brain seems to be swamped by the disadvantage of being big. Large species tend to reproduce later in life, have fewer offspring, require more resources and larger territories, and catch the attention of humans, either as food or as predators. Hunting pressure or reductions in available space can hit them particularly hard. 7/7/2015 203 Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 Third, Marris ended with a list of other factors (besides brain size) that could affect extinction risk, like “variations in body size, diet, population density, home range, lifespan and growth rate.” She quoted Walter Jetz of Yale who argued that “analyses of extinction risk using many traits will probably be more powerful and accurate than predictions based on single traits.” Then she ended by pointing out that even Abelson waffles about the meaning of his own analysis: 7/7/2015 204 Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 Abelson is agnostic on how the extinction-brain size relationship should inform conservation efforts. One could argue for expending more resources on the smaller-brained species that are at high risk. Or one could decide to spend more energy smoothing the way for the smarter, more adaptable species, since they might have a higher likelihood of surviving. “All I can say is that I hope it is useful for whoever is making those decisions,” he says. Having diluted the ingredients of the social Darwinism bomb, Marris went on her way with a clear conscience. Scientific American reprinted the article205 7/7/2015 Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 Is the reference to social Darwinism inappropriate for an innocent little article like this about species conservation? They didn’t even mention Darwin or evolution, for crying out loud. Is it not a fact of nature that animals differ in brain-to-body size ratios and basic intelligence? Didn’t Marris and Abelson adequately distance themselves from the really bad ideas of social Darwinism and their implications? Didn’t they give both sides, and remain agnostic on whether brain size matters at all to extinction? Isn’t this much ado about nothing? Isn’t it profoundly unfair to suggest a connection with 20th century atrocities of social Darwinism? 7/7/2015 206 Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 We certainly don’t want to be unfair to Marris or Abelson, but they should have known better. They could have done more to ensure safety precautions before playing with fire like this topic. They could have explicitly stated that their work has nothing to say about human intelligence or brain size. They could have specifically mentioned the harm that overemphasis on this trait in humans has done. 7/7/2015 207 Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 Those were the sins of omission. The sins of commission are: (1) using an incendiary title, “Mostly the big-brained survive”; (2) engaging in useless speculations that are impossible to prove: (3) assuming that brain size correlates with intelligence (perhaps not: quality might matter more than quantity); (4) linking intelligence to survival; (5) assuming that the smart are worth saving more than the stupid; (6) shuffling off the responsibility for the decision to others. Abelson said he hoped his information might be “useful” to “whoever is making those decisions” – i.e., what species deserve saving from extinction, the smart or the dumb. Can you imagine a scientist using 7/7/2015 208 that excuse in Nazi Germany? Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 The Darwinist mindset is that nature favors the fit, and the fit are the smart and the strong. Says who? Jesus Christ taught to honor the weak and reach out to the feeble-minded. He took the children in his arms and said that the kingdom of God belongs to such as these. We’re all weak and stupid compared to our Creator. We should each individually try to develop the gifts and talents God has given us to their fullest extent, to improve our intelligence, wisdom and strength, so that we can help our neighbor in time of need. A society that cares for its weaker members while maintaining individual responsibility is a healthy society. The social Darwinist societies viewed the weak as parasites and 7/7/2015 209 burdens that nature itself sought to eliminate. Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 Some readers may dislike the previous paragraph because it mentions God and Jesus. OK then, stick to the science. Are you not embarrassed by the sloppy science Abelson did, Marris promoted, and Nature printed? It’s useless and illogical. The basic hypothesis is that smarts help you avoid extinction. That idea is more full of holes than Swiss cheese. They know it: Marris said that being smart has just as many disadvantages to fitness as advantages. 7/7/2015 210 Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 Later, she aired Jetz’s list of factors that could matter just as much to survival: “variations in body size, diet, population density, home range, lifespan and growth rate.” That’s probably not an exhaustive list. It’s illogical, too: if nature favored the smart, then why are the dumb still around? Even if you restrict the category to just mammals, or just rodents, you would expect all the dumb ones to have gone extinct long before now, and natural selection to have brought the survivors to a high level of intelligence. Clearly that hasn’t happened or Abelson would have a flat curve, and 7/7/2015 211 nothing to measure. Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 Finally, animal intelligence should have nothing to do with decision-making about conservation. We don’t let turkeys go extinct just because they are dumber than crows. Even if Darwinists do not want to believe that our Creator has entrusted humans with a stewardship over the creatures of this world, they cannot get away from ethics. Someone needs to decide how to spend limited resources on conserving what species we can. Did you notice that conservation implies helping the weak? We are the smartest animals on the planet, right? All the others are dumber than us. We’re fit; we’ve survived so far. If they were consistent Darwinists, why should they care? Even with our intelligence, there are questions whether we will be smart enough to avoid destroying ourselves and 7/7/2015 212 everything else. Roots of a Dangerous Darwinian Doctrine Live On 危险的达尔文主义根源仍在 In short, for these reasons and more, we do not exonerate Marris, Abelson, Nature and Scientific American for posting this pseudoscientific poison. It is empirically unsound, practically useless, and dangerous. Let them all re-read the history of the 20th century and be reminded that such thinking can be used to justify unspeakable horrors. Time to shed these notions and stop blessing them with the name of science. 7/7/2015 213 Can Science Explain Mass Murder? 科学可以解释大规模屠杀? As the carnage of the latest mass murder is being assessed, TV commentators look predictably to psychologists for answers. Psychology has a questionable past as a science. Nearly every fad theory since its inception has been overturned. Even today, the field is riddled with scandal (11/05/2011), and their methods are questionable (7/05/2012). Psychiatry is supposed to be a step better, since one has to earn an M.D. to be a psychiatrist. But recently, their own “Bible” of diagnosis, the DSM-V, has been criticized as politically incorrect mumbo-jumbo that is so wrong it’s not even wrong (5/18/2012). 7/7/2015 214 Can Science Explain Mass Murder? 科学可以解释大规模屠杀? Yet when tragedy happens, and people search for answers as to what would motivate a person to commit mass murder, the experts that TV anchors call on are not Bible scholars, pastors or theologians. It’s psychologists and psychiatrists with their presumed appeal to offer “scientific” answers. 7/7/2015 215 Can Science Explain Mass Murder? 科学可以解释大规模屠杀? To date, there is not enough information about James Holmes’ background for anyone except perhaps his parents to have an informed opinion about what made him shoot an assault rifle into a crowded theater this morning. All that is known is that this PhD candidate in neuroscience was not your typical mass murderer. He was smart, and his act had to be premeditated. It was not a sudden snap, but a decision that had a history. The details will surely be forthcoming as the investigation proceeds. One fair assumption is that his studies in neuroscience at UC Riverside and University of Colorado were saturated with Darwinism and materialism, with their inherent meaninglessness and 7/7/2015 216 lack of personal responsibility. Can Science Explain Mass Murder? 科学可以解释大规模屠杀? What doesn’t help at all is for fake experts in psychology (“soul science”—a contradiction in terms) to lend their useless opinions and empty jargon to fill up air time. It wasn’t hard to find them, as usual, tossing out their meaningless words, like psychosis, neurosis, depressive disorder, as if that represents understanding. (You can play psychologist yourself. Just watch some person do something you don’t understand, and give it a label: “impulsive reverse toilet paper roll placement disorder.” ) Even the more commonly-used disorders cannot be diagnosed with any certainty; individual psychiatrists often come up with a different diagnosis for the same patient. This is indicative of quackery. Meanwhile, 7/7/2015 217 experts on the Bible were hard to find in the discussion. Can Science Explain Mass Murder? 科学可以解释大规模屠杀? The Bible has the Operations Manual from the Manufacturer. That should be the beginning point of wisdom for any human who wishes to qualify as an expert. “The fear of the Lord is the beginning of wisdom, and the knowledge of the Holy One is understanding,” Solomon said (Proverbs 9:10). This implies that secular psychologists and psychiatrists are not even at the beginning; in fact, they are behind the beginning, marching off in the wrong direction— their own understanding (Proverbs 3:5– 7/7/2015 218 6, Psalm 1). Can Science Explain Mass Murder? 科学可以解释大规模屠杀? Any intersection of their teachings with reality happens either by chance (the broken clock that is right twice a day), or from common sense observation, such as “students learn better when they concentrate” or “experiencing awe makes you feel better” (seriously; see Live Science). All their false teachings about motives of the soul stand in opposition to the Manual from the only One in the universe who knows what makes us tick. 7/7/2015 219 Can Science Explain Mass Murder? 科学可以解释大规模屠杀? The brain is a physical organ that can develop physical problems. These physical problems can affect behavior. The diagnosis is not “mental illness” but physical illness causing behavioral symptoms. To call it “mental illness” when someone with no physical brain problems (and in fact a good record of intelligence and achievement) goes off on a shooting rampage completely overlooks the real root of the problem: sin. Jeremiah wrote, “The heart is deceitful above all else, and desperately wicked; who can know it?” (Jer. 17:9). Solomon warned his son to “Keep watch over your heart with all diligence, for out of it spring the issues of life” (Proverbs 4:23). Real moral choices in life can lead to horrendous evils if unchecked, even if they simmer 220 7/7/2015 Can Science Explain Mass Murder? 科学可以解释大规模屠杀? As we watch the investigation into the Holmes case, look for evidence of either a physical problem or a sin problem. Initial hints show him obsessed with hard rock music and violent movies. Don’t be snookered into buying the snake oil of falsely-so-called scientists peddling “Joker Resemblance Syndrome” or “Movie-Reality Dualism Incompatibility Disorder” or whatever else they will try to label it. The word is sin. Sin includes hate, envy, jealousy, lying, and lack of self-control – all sins that Holmes could have nurtured till they festered, leading to that heinous act of mass murder. It is not compassionate to excuse his sin as some kind of psychological syndrome. We are all personally responsible for our actions. Each one of us will have to give an account to our Maker. “For the wages of sin is death, but the gift of God is eternal life in Jesus Christ our Lord” (Romans 6:23). 7/7/2015 221 Dark Matter Remains Missing 暗物质仍然失踪 The most sensitive test to date for dark matter in the form of weakly interacting massive particles (WIMPs) has turned up nothing. Live Science announced that a sensitive underground detector in Italy has turned up no definitive evidence for WIMPs after 13 months of searching. This either means (1) WIMPs are harder to detect, (2) WIMPs don’t exist, or (3) dark matter is MACHO: Massive Compact Halo Objects made up of ordinary matter. Serendipitously, the article was accompanied by a picture of a macholooking bodybuilder advertising a muscle-building 7/7/2015 222 product. Dark Matter Remains Missing 暗物质仍然失踪 Reporter Clara Moskowitz said that “Dark matter is thought to make up about 83 percent of the matter in the universe, yet scientists can’t see or touch it.” She didn’t specify who thought this. By now everyone has heard the tentative reports of the Higgs Boson being found at last. John Horgan put the discovery in context at Scientific American, remarking that “the Higgs doesn’t take us any closer to a unified theory than climbing a tree would take me to the Moon.” He also had some sharp words about the political hype over the misnomer, “God particle.” 7/7/2015 223 Dark Matter Remains Missing 暗物质仍然失踪 If they want to keep looking for the mysterious unknown stuff, nothing is stopping them, as long as they pay for it themselves. It’s happened before (alchemy, phlogiston, caloric). There should be a reasonable time limit and funding limit before requiring them to drop a dead-end theory and work on something that explains 83% of reality better. 7/7/2015 224 The Sociology of Climate Science 气候科学社会学 What has become known as “climate science” offers an opportunity to investigate the sociology of science and ask how political biases influence individual scientists. Since the lukewarm political response to the Rio conference, news articles indicate that climate science has a climate of its own – one that’s heating up over the inability to convince the public. 7/7/2015 225 The Sociology of Climate Science 气候科学社会学 Punk eek in the data: Even before the Climategate scandal, skeptics of human-caused global warming pointed to historical warming trends that preceded factories and SUVs. Another paper in Science this past week added to the ways that non-anthropogenic factors can cause major climate changes. Wortman and Paytan published a paper proposing “Rapid Variability of Seawater Chemistry Over the Past 130 Million Years” that “are likely to affect ocean productivity, the global carbon cycle, and climate,” even though humans were not around then in the evolutionary timeline (Science 20 July 2012: Vol. 337 no. 6092 pp. 334–336, DOI: 7/7/2015 226 10.1126/science.1220656). The Sociology of Climate Science 气候科学社会学 The fluctuations they found could be true of the entire geologic column. “The record is characterized by long phases of stasis, punctuated by short intervals of rapid change,” they said, reminiscent of punctuated equilibria (“punk eek”) in Stephen Jay Gould’s biological theory of evolution. The paper was summarized by Science Daily. “Humans get most of the blame for climate change, with little attention paid to the contribution of other natural forces,” the summary began. “Now, scientists from the University of Toronto and the University of California Santa Cruz are shedding light on one potential cause of the cooling trend of the past 45 million years that has everything to do with the chemistry of the world’s oceans.” Whether cooling 7/7/2015 227 trend or heating trend, the point is that humans didn’t do it. The Sociology of Climate Science 气候科学社会学 Laughing gas: Another factor in the battle for public acceptance of anthropogenic global warming is the apparent silliness of some of the scientific claims. On New Scientist, for instance, Michael Marshall headlined his latest article, “Belch of laughing gas could heat up our planet.” He wasn’t talking about climate skeptics laughing over the latest claims, releasing carbon dioxide in their breath, but natural releases of nitrous oxide after the ice age. Even so, part of the problem for skeptics is making sense of the conflicting data. Each new revelation is greeted with a tentative announcement: it “could” heat up our planet. But how would anyone test the idea? This natural gas release, long before the industrial revolution, opposes putting humans at fault: if ancient warming released laughing gas, why should we be blamed if current ice sheet melting releases it again? 7/7/2015 228 The Sociology of Climate Science 气候科学社会学 Drastic actions: A third factor antagonizing the public is the extremity of proposed measures to fight global warming. The proposed redistribution of wealth by taxing of industry is well known, but some measures are even more severe. National Geographic listed “6 Extreme Climate Fixes” that “geoengineers” are proposing to reverse human-caused warming, including dumping vast amounts of iron into the ocean to promote plankton blooms, creating “artificial volcanoes” to pump reflective particles into the atmosphere, creating seaweed farms, cooking agricultural waste, “greening” the desert, and building an armada of cloud-making ships. Most of these ideas would barely make a dent in the problem as climate scientists fear it. What’s more, they fail to ask the logical 7/7/2015 229 follow-up question, “At whose expense?” The Sociology of Climate Science 气候科学社会学 Presumably, it is concern for the biosphere driving the urge to stem global warming, yet some of the proposed measures could be extremely harmful to species or could shift the food chain in unexpected ways. Environmentalists have a reputation for stopping private construction projects and preventing landowners from making decisions about their own property out of concern for endangered species. Where were they when became widely known that “green energy” windmills were killing thousands of birds and bats each year? Where are they now with the 7/7/2015 230 proposal to alter the world’s oceans? The Sociology of Climate Science 气候科学社会学 Selective evidence: Members of the public might be understandably forgiven for expressing doubt when anything and everything is summoned as evidence for anthropogenic global warming: cold winters and warm winters, wildfires and excessive rains. Are the fearmongers crying wolf too often? Nature News held up the ominous spectre of wildfires to human guilt: “As temperatures soar, forests blaze and houses burn, the media and public may be forced to face up to the reality of a changing climate, says Max A. Moritz.” Moritz did not put wildfire statistics into any historical context, nor did he take into account the encroachment of human habitation into forested areas. For these and other reasons, one commenter didn’t buy it: “Once again Nature editors are pushing the catastrophic man made global warming mantra,” he complained. 7/7/2015 231 The Sociology of Climate Science 气候科学社会学 Selective indignation: At the BBC News, reporter Richard Black was apparently more concerned over the news that the Norfolk police force, after two and a half years, is dropping its investigation into the release of the emails in the Climategate affair, than he was of the lies and coverups by the IPCC exposed in those documents: 7/7/2015 232 The Sociology of Climate Science 气候科学社会学 Here was a crime with international ramifications that happened on their patch — the theft and release of more than 6,000 emails and other documents that lit a fire under mainstream climate science, perhaps contributing to the torpor in the UN climate process and raising the level of doubt in public minds. Yet despite engaging help from the UK’s specialist e-crime unit, IT security consultants and police forces in other countries, they’ve 7/7/2015 233 identified not a single suspect. The Sociology of Climate Science 气候科学社会学 This kind of selective indignation understandably rankles climate skeptics who want the focus to be on the data, not the leakers. These same people did not show similar outrage over Wikileaks actions that jeopardized national security; some of them actually cheered it. 7/7/2015 234 The Sociology of Climate Science 气候科学社会学 As an academic discipline, the sociology of science seeks to uncover non-empirical factors that cause scientists behave the ways they do: peer pressure at conferences, consensus construction and maintenance, treatment of maverick views, and more. Empirical scientists have just as much right to return the ball and question the sociological biases of the sociologists and the validity of their data. Onlookers can watch and decide whether any human being acting in the role of scientist 7/7/2015 235 is free of bias. The Sociology of Climate Science 气候科学社会学 Climate change (a.k.a. global warming) if off-topic for CEH except in the fact that the same doctrinaire warming advocates tend to be doctrinaire Darwinians. They also tend to be political leftists by virtue of the fact that they expect the government or the UN, not the people, to make decisions for everyone else, with no regard to individual rights, private property or the burden on taxpayers. Incidentally, some of them display the same carelessness with data – willingness to ignore data that contradicts their ideology. Understanding the political dynamics of this parallel issue can go a long way to interpreting the next news from the Darwin 7/7/2015 236 Party. Asteroids as Water Balloons Gave Us Oceans 小行星像水气球给我们海洋 Planetary scientists are looking to asteroids as the source of Earth’s water – not from evidence, but from desperation. The Bible’s book of Genesis describes Earth covered with water from its creation. Not so, say the secular evolutionists: Earth began as a hot, dry, rocky body spewing volcanoes and facing a bombardment of space debris. Problem: why is it covered with water today? Even though the oceans are a relatively thin veneer on the globe, making up about 1% of Earth’s mass, their prominence is one of the defining characteristics237of 7/7/2015 our “water planet.” Asteroids as Water Balloons Gave Us Oceans 小行星像水气球给我们海洋 There have been three suggestions to answer the “H2O Enigma” (see 3/26/2002): a lucky strike by a big wet planetesimal, condensation from the solar nebula, and comets. The first two hypotheses are pretty much defunct, leaving comets. But for the last several years, secular planetary scientists have doubted that comets brought the water (see 11/03/2009), primarily because the hydrogen-to-deuterium ratio in cometary ice differs substantially from Earth water. (Deuterium abundance is thought to increase with distance from the sun.) In addition, direct observation of comets by Stardust and Deep Impact have shattered theories about their origins 7/7/2015 238 (12/27/2007, 9/24/2008, 4/18/2011). Asteroids as Water Balloons Gave Us Oceans 小行星像水气球给我们海洋 As Space.com reported recently, it’s unlikely scientists can retreat back to condensation from the local solar nebula. The so-called “snow line” in planet formation theory is now thought to be even farther out than previously believed. Earth started out dry. Volatiles like water had to come special delivery. Taking all the difficulties into account, NASA’s Astrobiology Magazine considered one last option: asteroids. In “Meteorites Most Likely Source of Earth’s Water,” NASA pointed to work by Carnegie Institute scientists who believe water-bearing carbonaceous chondrites, with their lower deuterium ratios, could have been the delivery vehicles. Because the deuterium ratio is lower, they might have formed in the asteroid belt. The last 7/7/2015 239 paragraph shows this is only a suggestion: Asteroids as Water Balloons Gave Us Oceans 小行星像水气球给我们海洋 “Our results provide important new constraints for the origin of volatiles in the inner Solar System, including the Earth,” Alexander said. “And they have important implications for the current models of the formation and orbital evolution of the planets and smaller objects in our solar system.” A constraint is not a theory any more than an implication is. Scientists generally frown on ad hoc explanations that rely on luck to fix a problem. 7/7/2015 240 Asteroids as Water Balloons Gave Us Oceans 小行星像水气球给我们海洋 Did any of them think this through? How many asteroids would it take? Unlike comets, asteroids are mostly rock. It would seem to squeeze enough water out of the rocks of carbonaceous chondrites, they would have to coat the whole Earth with a veneer of them. That should be clearly detectable. Also, the timing is critical in their hypothesis. It would have to arrive after the volcanoes stopped burying the land in lava; what made the asteroids come in then? Furthermore, the asteroids had to be the right size. Too big, and they would have boiled away any oceans being 7/7/2015 241 formed. This theory is ad hoc all over the Earth. Asteroids as Water Balloons Gave Us Oceans 小行星像水气球给我们海洋 There is nothing in science that demands a bottom-up explanation. Science should go with where the evidence leads: top-down (i.e., intelligent design) or otherwise, without a pre-selected bias. A theory that includes an eyewitness account should be given more credence than one that relies on inferences from the unobservable past (unobservable, that is, to humans). For these reasons, given the implausibilities of the secular account, the Genesis account can be called the most accurate scientific explanation of the origin of the Earth’s oceans. Peter is harsh on the latter day uniformitarian scoffers, claiming they willfully forget that the world was created with its water from the beginning (2 Peter 3:3– 6). The scientific data did not demand their bottom-up, 7/7/2015 242 mindless view. it was a choice. Man Blamed for Living Fossil Extinction Threat 活化石灭绝的威胁责怪人 The chambered nautilus is on the decline, after 500 million years of survival from the world’s greatest extinction events. Guess who’s to blame. At the Philadelphia Inquirer, Faye Flam wrote about the nautilus, a “living fossil” that has survived all that planet Earth could throw at it for 500 million years. It survived the Permian Extinction that wiped out 90% of species on Earth, and the fabled K-T extinction event that wiped out the dinosaurs. But now, its days are numbered, and humans are to blame. Presumably, it’s because hunting of the prized shells caught them by 7/7/2015 243 surprise: Man Blamed for Living Fossil Extinction Threat 活化石灭绝的威胁责怪人 So as hardy as these creatures have proven over hundreds of millions of years, a new fitness factor is becoming increasingly important — the ability to coexist with 7 billion human beings. There’s nothing the nautilus can do to adapt to the threat from humans — it came on too suddenly. The future of these animals depends not on what they do, but on what we do. 7/7/2015 244 Man Blamed for Living Fossil Extinction Threat 活化石灭绝的威胁责怪人 This is Flam’s latest entry under “Planet of the Apes,” a blog on evolution. Her post, echoed on PhysOrg, contained some implausible elements. For one, was human hunting of the nautilus any more sudden than an asteroid impact? Second, how many out of 7 billion human beings are nautilus fishermen? Third, how big is the nautilus habitat in the vast oceans of the world? Fourth, what does the nautilus have to do with evolution? 7/7/2015 245 Man Blamed for Living Fossil Extinction Threat 活化石灭绝的威胁责怪人 Ammonoids, of which the nautilus is a member, are complex animals that appeared in the Cambrian Explosion, “Darwin’s Dilemma” – the abrupt, non-evolutionary appearance of all the animal phyla in a geological eye-blink in evolutionary terms. “Nautiloid fossils have been dated as early as 500 million years ago — soon after animals started leaving fossils,” she wrote. And they are “living fossils,” basically unchanged in body plan for over 500 million years. 7/7/2015 246 Man Blamed for Living Fossil Extinction Threat 活化石灭绝的威胁责怪人 In addition, Flam reduced evolution from the realm of natural law to happenstance: The story of the nautiloids helps illustrate the role of chance in evolution. Extinction doesn’t reflect some kind of flaw or weakness or inability to adapt. The term “fitness” as scientists use it depends on the environment — don’t think of workouthardened athletes but of individuals that fit well into their surroundings. And on this planet, the surroundings are always subject 7/7/2015 247 to change. Man Blamed for Living Fossil Extinction Threat 活化石灭绝的威胁责怪人 But if fitness is chance adaptation to a chance environment, everything is chance. This not only undermines the position of many Darwinians about fitness and adaptation for over a century, it means that evolutionists have no grounds for predicting or explaining anything in the living world. 7/7/2015 248 Man Blamed for Living Fossil Extinction Threat 活化石灭绝的威胁责怪人 Undoubtedly Faye Flam confidently expected to hit a grand slam as a pinch hitter for Darwin, but count the strikes: (1) Cambrian explosion, (2) living fossils, (3) Stuff Happens. She’s out, but mercifully we’ll give her one more pitch. Tell us, Ms. Flam, does the nautilus look like a product of random mutation? 7/7/2015 249 Man Blamed for Living Fossil Extinction Threat 活化石灭绝的威胁责怪人 The spiral shells are divided into chambers, the biggest outermost one providing a home for the creatures and the empty ones providing an adjustable buoyancy system that allows the nautilus to move up and down after food. Not only is the nautilus a member of an ancient lineage, but individual creatures are long-lived. They may live upwards of 100 years… When it comes to smell, “they are like wolves, picking up an unbelievably small number of molecules,” [Peter] Ward said. Nice try. Game over. (The Darwin team’s manager is 7/7/2015 heard yelling, “Whose side are you on, anyway?”)250 Evolution Falsely So Called 所谓进化虚假 Evolutionary theory gets credited for changes that really do not help Darwin’s view of a universal tree of life. Three examples show how. Toxin resistance by insects: Science Daily reported on a study out of Cornell University that showed the same mutation occurring in four orders of insects, conferring resistance to plant toxins called cardenolides. “This is truly a remarkable level of evolutionary repeatability and suggests that evolving resistance to the plant toxin had very few effective options,” lead research Anurag Agrawal said, hinting that evolution might in some way be predestined. But as Dr. Michael Behe argued, single point mutations, even double mutations, lie within the “Edge of Evolution” and can thus be explained by 251 7/7/2015 chance. Evolution Falsely So Called 所谓进化虚假 Insects gaining the mutation will survive and proliferate because the cardenolides will no longer bind to enzymes required by the insects’ sodium pump. The insects are still the same species, however. They have not generated any novel genetic information, let alone a new irreducibly complex structure. Point mutations cannot explain the origin of the sodium pump and the enzyme in the first place. At best, this mutation represents a loss of genetic information that happened to help the insects escape death, so it falls in the category of “cutting of a hand makes you immune to handcuffs” – hardly a mechanism that can generate the diverse and complex wonders of the living world. See also the explanation 7/7/2015 252 at Uncommon Descent. Evolution Falsely So Called 所谓进化虚假 Speciation by gene duplication: A case of a new “species” of monkeyflower emerging from a whole-genome duplication was reported by Live Science. The new hybrid apparently cannot crossbreed with other similar monkeyflowers, but whether this represents “newly evolved species” seems a stretch; it is still a monkeyflower, very similar in appearance to the sibling monkeyflowers without the duplication. “While many new species of plants are thought to arise this way, it has only been witnessed amongst wild plants a handful of times in history,” one scientist was cited as saying. He also placed most species evolution in the unobservable past, claiming, “most species originated thousands of years ago” by processes he could only describe as a 7/7/2015 253 “series of unlikely events”. Evolution Falsely So Called 所谓进化虚假 Again, no new genetic information was added. Nothing was stated about the flowers fitness other than that is seen growing in the wild (most hybrids are sterile). Since duplicating this paragraph would not explain the origin of the paragraph or make it more meaningful, it’s a stretch to call this evolution as Darwin envisioned it; if anything genetic duplication adds to genetic load—a burden on the DNA copying mechanisms that now require double the work with every cell division. 7/7/2015 254 Evolution Falsely So Called 所谓进化虚假 Darwin’s robots: The most egregious examples of evolutionary excess come when Darwin’s name gets attached to intelligent design. Michael White did this in Science in his review of John Long’s new book, Darwin’s Devices: What Evolving Robots Can Teach Us About the History of Life and the Future of Technology. (White, “Evolution and Robots,” Science 20 July 2012: Vol. 337 no. 6092 pp. 294–295, DOI: 10.1126/science.1224874). White, who boasts of studying “the evolution of robots” himself, enjoyed Long’s “compelling and wide-ranging conversation.” he said. “This includes discussions of the mechanics of fish backbones, how we practice science, the nature of evolution, what it means to be intelligent, our dystopian robot future, and, most important, the crucial role of good models in science.” It appears both White and Long could255 7/7/2015 use a refresher course on the “nature of evolution” — Evolution Falsely So Called 所谓进化虚假 Darwin’s Devices recounts the efforts of Long and his colleagues to study the biomechanics and evolution of vertebrae in fish using autonomous, aquatic robots as models. Long is interested in whether natural selection for more efficient food-seeking behavior could have led to the appearance of stiff backbones in the earliest vertebrates. By allowing robots with different backbone properties to compete with each other and by having the winners pass their traits down to the next generation of robots, Long and his collaborators follow backbone evolution 7/7/2015 256 in their population of robotic fish. Evolution Falsely So Called 所谓进化虚假 Clearly, Long was doing artificial selection—a form of intelligent design— not natural selection. He had a goal and he acted as the intelligent selector. He also designed the robotic fish to begin with. How he could leap from ID selection into “natural selection,” which has no goal and no intelligent selector, shows that misconceptions about Darwinism persist even among Darwinians. 7/7/2015 257 Evolution Falsely So Called 所谓进化虚假 Are you getting good at spotting the magic words? Darwinians love magic words. Here they were: “whether natural selection… could have led to the appearance of”. That’s the sleight of hand: (1) could, invoking the Stuff Happens Law by the power of suggestion, (2) led to, a fallacy of goal-directed behavior inconsistent with Darwin’s undirected processes, and (3) the appearance of, an “abracadabra” phrase conveying no information about how a stiff backbone could have “appeared” by any kind of scientifically describable process. 7/7/2015 258 Evolution Falsely So Called 所谓进化虚假 Notice also the investigator interference at every stage. Long was “allowing” the robots “to compete” with each other. He allowed “winners [to] pass their traits down”. Who were the winners? The ones Long predetermined would have stiff backbones, of course. If this is what it means to “follow backbone evolution,” then a puppeteer is following puppet psychology. If Long really wanted to test natural selection (even granting the existence of his designed robotic fish), he would have had to turn them loose, then walk out, lock the doors, and come back in a million years to observe what happened – without interfering in any way. It appears that before Darwin skeptics can win debates with Darwinians, they will have to teach Darwinians what Darwinism is. 7/7/2015 259 Humans by Mistake 人类的错 Scientists from Scotland claim to trace our origins to a genetic mistake 500 million years ago. In large bold print on Live Science, reporter Jennifer Viegas announced this headline: “500 Million-Year-Old ‘Mistake’ Led to Humans.” The opening tried to dramatize claims made by scientists at the University of Dundee about a marine creature named amphioxus: 7/7/2015 260 Humans by Mistake 人类的错 Over 500 million years ago a spineless creature on the ocean floor experienced two successive doublings in the amount of its DNA, a “mistake” that eventually triggered the evolution of humans and many other animals, says a new study. The good news is that these ancient DNA doublings boosted cellular communication systems, so that our body cells are now better at integrating information than even the smartest smartphones. The bad part is that communication breakdowns, traced back to the very same genome duplications of the Cambrian Period, can cause diabetes, cancer and neurological disorders. 7/7/2015 261 Humans by Mistake 人类的错 It’s a long way from amphioxus, indeed. PhysOrg called this an “evolutionary upheaval” that resulted in an “evolutionary leap” over 500 million years. One of the scientists justified this storytelling by claiming it sheds light on the origin of disease: “Analysis of these gene families from an evolutionary point of view helps to navigate through the increasingly large data sets on protein interactions in a more focused and productive way, speeding the way towards establishing the links between particular proteins and diseases as well as highlighting new potential disease targets.” He did not explain why comparative genomics requires the assumption of evolutionary common ancestry, nor did he give any measure of focus and productivity using the evolutionary 7/7/2015 262 point of view. Humans by Mistake 人类的错 Let’s be logical, here. Professor, if we are the result of a mistake, then you are the result of a mistake. Ergo, unless you can explain the evolution of truth, your claim about our origins is mistaken. Consequently, it is a mistake to pay your theory any attention. Q.E.D. 7/7/2015 263 Humans by Mistake 人类的错 This is a good one to keep for the day the Darwin idol collapses. Enlightened philosophy of science teachers will have fun showing their students what professors with PhD’s once claimed was solid science. The professor will hear gasps from the class when he explains that the media reported these things uncritically, and nobody laughed. 7/7/2015 264 Scientific Institutions Engage in Leftist Advocacy 科研机构从事左翼宣传 For an enterprise supposedly as apolitical and bias-free as science classically is supposed to be, conservatism is surprisingly rare. Since we last reported the leftist bias in scientific institutions (Jan 19, 2012), has there been any shift to the right? any penitence for embracing and promoting one political party? No; it has gotten worse. Here are just a few of the most egregious examples in recent days. These not only state leftist positions, but openly advocate them. 7/7/2015 265 Scientific Institutions Engage in Leftist Advocacy 科研机构从事左翼宣传 Anti-Israel: The only redeeming feature of this example is that at least Science magazine published a protest letter by John R. Cohn of Thomas Jefferson University. The Science May 18cover story was a special feature on “Human Conflict.” Out of all the possible pictures of human conflict imaginable, what did the editors of Science choose? It was a photo of a bombed-out building attributed to the Israeli Defense forces. Cohn’s letter, published two months later, accused the editors of politicizing 7/7/2015 266 science: Scientific Institutions Engage in Leftist Advocacy 科研机构从事左翼宣传 I am writing in reaction to the cover photo and accompanying caption selected for the 18 May special issue on Human Conflict. It seems disingenuous to claim that of all the world’s conflicts, a building identified as destroyed by the Israel Defense Forces (IDF) was “not [chosen] for any political message or endorsement.” Nobody eschews war more than Israelis, who, unfortunately, also know the consequences. If the editors wanted striking visual impact and gruesome evidence of inhumanity, there were better choices: the killing fields of Cambodia, the destruction of the World Trade Center, Rwanda, Dresden, Hiroshima, Bataan, Darfur, Armenia, Normandy, Auschwitz… 7/7/2015 267 unfortunately, the list of greater carnage is nearly endless. Scientific Institutions Engage in Leftist Advocacy 科研机构从事左翼宣传 By identifying the IDF as perpetrators, the caption undermined the photo’s role as a generic illustration of the consequences of conflict. Indeed, there was no need to identify the details. They were a distraction. The photo no longer represented abstract human violence, but rather one more illustration of Israel, taken out of context. Portraying Israel as the aggressor obscures the fact that the country is trying to defend itself against decades of assaults provoked by ethnic hostility—attacks still taking place. That is politicized science, which 7/7/2015 268 serves to encourage—not discourage—conflict. Scientific Institutions Engage in Leftist Advocacy 科研机构从事左翼宣传 Scientists advising Obama: What should a science news site have to do with presidential politics? Nothing, really. But PhysOrg published the views of two UK scientists taking it upon themselves to act as his campaign advisors: “Obama needs to show Americans he’s still ‘one of them’,” the headline reads, followed by PhysOrg’s summary, “To win a second term in office, President Obama needs to persuade voters that he is still one of them – and recapture some of the charisma that help [sic] propel him to the top four years ago.” No such advice was found 7/7/2015 269 anywhere on PhysOrg advising Romney how to win. Scientific Institutions Engage in Leftist Advocacy 科研机构从事左翼宣传 Scientists advocating for leftist NGO’s: It is common knowledge that environmental groups, particularly non-governmental agencies (NGOs) such as the Sierra Club, are predominantly (though not exclusively) leftist in ideology – particularly those lobbying for government intervention in private property rights and action against global warming. Another PhysOrg article advocated this in its headline: “Environmental groups should pool efforts to reach the public.” One would think a science news site would stick to the facts about the environment, not provide advice on how to sway 7/7/2015 270 public opinion. Scientific Institutions Engage in Leftist Advocacy 科研机构从事左翼宣传 Unhealthy theists: Another prominent science news site promulgated a highly questionable psychological study that materialists are healthier – questionable because such studies are loaded with untestable variables. In “Mind Vs. Body? Dualist Beliefs Linked With Less Concern for Healthy Behaviors,” Science Daily uncritically promoted the idea that those who believe the mind is separate from the brain are likely to engage in unhealthy behavior, calling the research “findings” instead of suggestions or opinions. Without doubt, hard-core secular Darwinists are likely to be materialists, not 7/7/2015 271 attributing the mind to a soul or spirit. Scientific Institutions Engage in Leftist Advocacy 科研机构从事左翼宣传 Same-sex marriage and the church: A particularly egregious example of leftist ideology masquerading as “science” is found in a PhysOrg story entitled, “College students likely to disagree with religious teachings that homosexuality is a sin.” Saturating this report about University of Michigan Michael Woodford’s views on how to overcome student’s parental and church teachings about marriage are biased words intended to show conservatives as backward and liberal churches as open-minded. PhysOrg joined left foot in to the leftist professor’s advocacy of same-sex marriage: “College students’ beliefs about same-sex relationships can be shaped by their church’s teachings, but some are willing to oppose their religion’s position on the issue, a new University of Michigan study indicated. And this can influence students’ views about same-sex marriage.” 272 7/7/2015 Scientific Institutions Engage in Leftist Advocacy 科研机构从事左翼宣传 Topics like sin and marriage have no place in a science news site, but PhysOrg’s complicity in Woodford’s anticonservative advocacy that seeks to undo what parents and churches have taught their children echoes intolerant rhetoric this week from certain politicians attacking the Chick Fil-A food chain for its president’s vocal stand for traditional marriage (see Family Research Council article). 7/7/2015 273 Scientific Institutions Engage in Leftist Advocacy 科研机构从事左翼宣传 Burn the heretics: What happens when a scientist goes rogue and steps outside the leftist consensus? He or she had better wear armor and combat boots, if not a flame-proof fireman’s suit. Look at the case of Mark Regnerus (U of Texas), whose politically-incorrect research (reported here 6/10/2012) indicated that traditional families are better for children than same-sex parent homes. All fury broke loose against him from the sociological science community, according to Christian Smith at the Chronicle of Higher Education, who likened their response to an “academic autoda-fé” (a reference to Spanish Inquisition celebrations of burning heretics at the stake). Regnerus’ attempt to state his findings in the gentlest, fairest, most tolerant manner possible were no protection. See also “Science Lies Bleeding: A Ballad for Honesty” by Kathryn Jean Lopez 274 7/7/2015 at National Review. Scientific Institutions Engage in Leftist Advocacy 科研机构从事左翼宣传 Wait a minute, the reader hesitates … I’m confused. Aren’t liberals supposed to be the champions of tolerance? Aren’t these the ones promoting diversity? Isn’t their favorite word inclusion? Now you understand the mindset of the Darwin Party. With few exceptions, they are cut of the same cloth. Leftists whimper for academic freedom when in the minority. But once they get power, they become intellectual bigots and bullies, with no tolerance for the inclusion of diverse views outside of those that are progressive, leftist, liberal, 7/7/2015 275 and even radical. Scientific Institutions Engage in Leftist Advocacy 科研机构从事左翼宣传 If you find any politically conservative Darwinists who support traditional marriage, the US Constitution, private property rights, the free market, individual liberty, limited government, free speech and scientific integrity, send him to the embassy for protection from the next academic auto-da-fé. 7/7/2015 276 Animals Win the Gold 动物赢得金牌 As the Olympics begin in London, it’s fun to consider how animals would compete against humans. The BBC Nature News wrote up a list of amazing animals that, adjusted for size, could outperform humans in certain Olympic events. 100 meter sprint would be won by the cheetah, the brown hare, or the patas monkey. Marathon could be run in under an hour by a pronghorn if it could sustain its peak rate that long; but humans are the ultimate long-distance runners 7/7/2015 277 (11/18/2004). Animals Win the Gold 动物赢得金牌 High jump: humans would have trouble, size for size, outcompeting grasshoppers, kangaroos or frogs. A nocturnal primate called the bush baby (see video clip) at human proportions could jump over two stacked double-decker London buses. Then there are jumping spiders, able to jump 30 times their body height, springtails, able to jump (at human size) over the Eiffel Tower. The gold would probably go to fleas, able to jump 200 times their size. Javelin champs in the animal world are the bolas spider (see video), and that hat thrower fungus, a 5 7/7/2015 278 cm organism able to throw a sport 2 meters. Animals Win the Gold 动物赢得金牌 “Luckily,” reporter Jeremy Coles wrote, “modern Olympic athletes do not have to compete with nature’s greatest as they would be out sprinted by a monkey, out jumped by a springtail and out thrown by a tiny fungus.” Science Daily posted a similar comparison of human-animal capabilities. 7/7/2015 279 Animals Win the Gold 动物赢得金牌 We may not fly like eagles or run like cheetahs, but we humans were given a remarkable suite of special abilities. What other creature can run a marathon, swim the English Channel, jump 2.5 meters, lift 167 kg overhead, dive from 20 meters flipping and spinning to enter the water without a splash, perform complex floor exercise moves to music, spin around a pommel horse by the hands, ride horses over hurdles, shoot arrows and bullets with extreme accuracy, and all the other Olympic feats – to say nothing of writing books, composing music, and showing compassion and stewardship 7/7/2015 280 over all the other creatures on the planet? Animals Win the Gold 动物赢得金牌 What we can’t do, we can build: we fly aircraft to follow the birds, build submarines to follow the whales, and set up bases at the south pole to follow the penguins. We create protective coverings for all kinds of environments. No other animal explores space or ponders the origin and fate of the universe. No animal does science, prays, and shows true agape love. No other earthly being shows righteous indignation. No animals hold sporting events to celebrate their physical gifts. It’s not so bad being human. As we celebrate they joy of victory for those who have worked for years to become the very best, remember that we really are celebrating our Creator’s gifts to us. Let us use these281 7/7/2015 gifts to honor our Maker, not just ourselves. Left-Handed Amino Acid Puzzle Remains 左撇氨基酸之谜仍然存在 A NASA Goddard press release reported that amino acids found in the Tagish Lake meteorite (British Columbia, 2000) showed some preference for lefthanded aspartic acid, but less excess for alanine. As usual, the science news media (e.g., Astrobiology Magazine, Science Daily, PhysOrg) and blogs (e.g., Darwiniana) all echoed the press release uncritically, graphics and all, so Creation-Evolution Headlines will have to do the job they should have done: evaluate the significance of the claim and see whether it solves the long-standing homochirality problem in biology (for background, see here and here). 7/7/2015 282 Here are problems admitted by the press release: Left-Handed Amino Acid Puzzle Remains 左撇氨基酸之谜仍然存在 Only 2 of the 20 amino acids used by life were mentioned. The excess of one hand was 4x for aspartic acid, but only 8% for alanine. The scientists do not know what process created the excess, but it was not polarized light, because it must have occurred inside the meteorite. “Perhaps” it was due to properties of crystallization. The meteorite amino acids were enriched in carbon-13, not the carbon-12 common in life. 283 7/7/2015 Left-Handed Amino Acid Puzzle Remains 左撇氨基酸之谜仍然存在 An astrobiologist admitted, ” “Synthetic proteins created using a mix of left– and right-handed amino acids just don’t work.” Left-handed amino acids and right-handed sugars were noted as “a prerequisite for life.” All ordinary methods of synthetically creating amino acids result in equal mixtures of left– and right-handed amino acids. The finding complicates searches for extraterrestrial life, because it means finding one-handed molecules may not be a biomarker. 7/7/2015 284 Left-Handed Amino Acid Puzzle Remains 左撇氨基酸之谜仍然存在 Here are more problems not mentioned in the press release: Life requires 100% purity of one hand. A mere “excess” is not enough; one wronghanded amino acid ruins the protein chain. The astrobiologists still have no theory for how the meteorite enriched one hand in the aspartic acid. The astrobiologists still have no theory for how a prebiotic “cell” ended up with 100% pure 7/7/2015 285 amino acids. Left-Handed Amino Acid Puzzle Remains 左撇氨基酸之谜仍然存在 Their “snowball” analogy for how crystals might amplify the excess is worthless, because cells had to incorporate amino acids in solution, not as crystals. The article used wishful-thinking words like perhaps, could, and might a dozen times. The article said further experimentation is needed. In summary, since the press release proposes no physical theory for the excess, and no testable hypothesis for how the excess originated, could have been sustained, or could have been incorporated into life, the press release adds little more than anecdote to the puzzle of one-handedness, and nothing in the 7/7/2015 286 way of understanding. Left-Handed Amino Acid Puzzle Remains 左撇氨基酸之谜仍然存在 Same old story; irrelevant mumblings we’ve been reporting for over a decade (e.g.,2/17/2001, 5/09/2012; search on “homochirality” for more). Come back when you have a materialist explanation, not a just-so story. Intelligent design explains the observations. Face up to the physics, don’t twist them to your worldview, Darwinists. 7/7/2015 287 Science of the Ten Commandments 科学十诫 Thinking about the Ten Commandments reduces cheating, even for atheists. In his weekly TV program on Fox News, John Stossel interviewed Dan Ariely, psychology professor at Duke University. An iconoclastic reporter, libertarian and evolutionist, Stossel seems happiest when dismantling myths and showing that reality is often opposite what we believe or have heard. He seemed speechless, though, when Ariely brought up the Ten Commandments. 7/7/2015 288 Science of the Ten Commandments 科学十诫 Stossel was expressing the idea that everybody cheats. Ariely, a mythbuster himself, and not an obvious fan of the Decalogue, recalled an experiment he ran in which students reduced their cheating when asked to think about the Ten Commandments – even if they could not list them and didn’t believe the Bible. On his blog post July 1, he explained, “We once ran a study on cheating where we asked students to try to recall the Ten Commandments before an exam, and found that this moral reminder deterred them from cheating.” (For more detail on the experiment, see 7/7/2015 289 his May 26 article on the Wall Street Journal.) Science of the Ten Commandments 科学十诫 His blog post continued by citing an MBA professor, so upset with rampant cheating, that he asked his students to sign an honor pledge that listed the Ten Commandments and warned them if they violated it they would “be sorry for the rest of [their] life and go to Hell.” Needless to say, complaints and controversy ensued at that school, but Ariely ended with some wit: 7/7/2015 290 Science of the Ten Commandments 科学十诫 Still, though I don’t doubt its effectiveness, the question remains whether we want to invoke such stringent punishments (stringent for those who believe, that is) on an MBA exam. Judging from the reactions in this case, I’m guessing that for most people, the answer is “no.” But it also makes me wonder about the people who didn’t want to sign this pledge…. Stossel and Ariely must also be wondering what is it about the human psyche and the Ten Commandments that produces this kind of 7/7/2015 291 reaction in students but not apes. Science of the Ten Commandments 科学十诫 Well, no wonder. People have a conscience. Exercise: Run an experiment in which students are warned before an exam to ponder the Fifteen Evolutionary Gems (hear podcast on ID the Future). 7/7/2015 292 Olympic Plants Perform in Place 奥运植物执行到位 They may be rooted in the ground, but plants run their own Olympic organization. Command and control center: Running any large organization requires command and control. Plants have one, too – one that runs on hormones. A command and control center needs to respond to emergencies; plants can do that, too. To see how they accomplish these functions, read “Lighting up the plant hormone ‘command system’” on PhysOrg. The article ends with words from Zhiyong Wang of the 7/7/2015 293 Carnegie Institution: Olympic Plants Perform in Place 奥运植物执行到位 “This command system seems not only to accept various inputs, but also to send branches of output signals, too, because each component acts interdependently on shared targets, but also independently on unique sets of target genes,” Wang said. “This complex network contains multiple layers and controls major plant growth and developmental processes. We believe this network will be a major target for engineering high-yielding crops.” 7/7/2015 294 Olympic Plants Perform in Place 奥运植物执行到位 Intelligence agency: Another article on PhysOrg has the attention-getting title, “Tel Aviv University researcher says plants can see, smell, feel, and taste.” The first paragraph adds to the wonder: Increasingly, scientists are uncovering surprising biological connections between humans and other forms of life. Now a Tel Aviv University researcher has revealed that plant and human biology is much closer than has ever been understood — and the study of these similarities could uncover the biological basis of diseases like 7/7/2015 295 cancer as well as other “animal” behaviors. Olympic Plants Perform in Place 奥运植物执行到位 Prof. Daniel Chamovitz’s new book What a Plant Knows “could prompt scientists to rethink what they know about biology,” the article states. “Ultimately, he adds, if we share so much of our genetic makeup with plants, we have to reconsider what characterizes us as human.” He wasn’t thinking of people who “veg out” instead of working out, but noted similarities, such as the human response to light in their circadian rhythms that is similar to that in plants. They “see” by using light “as a behavioral signal, letting them know when to open their leaves to gather necessary nutrients.” They “smell” and 7/7/2015 296 have “memory” too– Olympic Plants Perform in Place 奥运植物执行到位 And that’s not the limit of plant “senses.” Plants also demonstrate smell — a ripe fruit releases a “ripening pheromone” in the air, which is detected by unripe fruit and signals them to follow suit — as well as the ability to feel and taste. To some degree, plants also have different forms of “memory,” allowing them to encode, store, and retrieve information. 7/7/2015 297 Olympic Plants Perform in Place 奥运植物执行到位 Even more intriguing, plants have some of the same genes that are implicated in breast cancer and cystic fibrosis in humans. “Plants might not come down with these diseases, but the biological basis is the same, says Prof. Chamovitz,” a remarkable fact hard to square with evolutionary theory which would put the common ancestor of plants and humans far back in the microbial world. 7/7/2015 298 Olympic Plants Perform in Place 奥运植物执行到位 Communications hub: The sight of a whole field of wildflowers blooming simultaneously is beautiful, but raises the question: How do they know when to flower? In a featurette about women in science, PhysOrg reported about professor Carolyn Dean who studied that very question. The short answer is that plant flowering genes have repressors that prevent flowering until environmental factors remove them. “The way this memory works is very conserved which means it works in a similar 7/7/2015 299 way in many organisms including humans.” Olympic Plants Perform in Place 奥运植物执行到位 Environmental responsibility: Plants are certainly part of “green” energy use and pollution control, but now, the American Chemical Society says that “Green plants reduce city street pollution up to eight times more than previously believed.” City planners would do well to include more ivy, hedges and planters in “urban canyons” to clean up their act, reported PhysOrg. 7/7/2015 300 Olympic Plants Perform in Place 奥运植物执行到位 As usual, these articles had little or nothing to say about evolution, because none of the findings are helpful to evolutionary theory. They provide negative arguments against Darwinism, such as requiring the complexity to appear inexplicably far back into some microbial common ancestor; and they provide positive evidence for intelligent design, such as the ability to “encode, store, and retrieve information.” The natural inference from our experience is that commonality in complex features implies common design. Follow this evidence to its logical conclusion, and you will 7/7/2015 301 undoubtedly enjoy the plants around you more. Peppered Moths Without Evolution 胡椒蛾没有进化 A new study shows that scientific research on moth camouflage does not require evolutionary theory. Evolutionary biologists from Seoul, South Korea filmed moths resting on tree trunks. According to PhysOrg, they were trying to understand how moths in the wild orient themselves on the bark for greatest camouflage. That’s a very different question than the ones asked by Kettlewell, Majerus and other past researchers who were looking for natural selection of peppered moths. In those old studies, camouflage was a happenstance, not a behavior within the moth. The opening paragraph referred to the old ideas as if preparing to dismiss them: 7/7/2015 302 Peppered Moths Without Evolution 胡椒蛾没有进化 Moths are iconic examples of camouflage. Their wing coloration and patterns are shaped by natural selection to match the patterns of natural substrates, such as a tree bark or leaves, on which the moths rest. But, according to recent findings, the match in the appearance was not all in their invisibility… Despite a long history of research on these iconic insects, whether moths behave in a way to increase their invisibility has not been determined. 7/7/2015 303 Peppered Moths Without Evolution 胡椒蛾没有进化 In other words, Kettlewell and Majerus didn’t take into account the moths’ behavior. They treated moths as passive creatures that would alight on tree trunks at random. They placed the selective power in the environment, with lower contrast producing greater camouflage, leaving the high-contrast moths vulnerable to birds. 7/7/2015 304 Peppered Moths Without Evolution 胡椒蛾没有进化 The South Korean researchers found, instead, that moth behavior plays a vital role in the camouflage. They “found out that moths are walking on the tree bark until they settle down for resting; the insects seem to actively search for a place and a body position that makes them practically invisible.” A video clip embedded in the article shows the moths doing this. 7/7/2015 305 Peppered Moths Without Evolution 胡椒蛾没有进化 To determine whether this final spot indeed made the moth really invisible, the researchers photographed each moth at its landing spot (initial spot) and at the final spot at which the moth decided to rest. Next, the researchers asked people to try to locate the moth from the photograph as quickly as possible. People had more difficulty finding the moths at their final spots than the same moths at their initial landing spots. Amazingly, this was even true for the species (Hypomecis roboraria) that only changed its resting spot on the tree bark without changing its body orientation. Therefore, the researchers concluded, that moths seems to actively choose the spot that makes them invisible to predators. How do they know how to become invisible? The research team is now trying to 7/7/2015 306 answer this question as the next step. Peppered Moths Without Evolution 胡椒蛾没有进化 The only mentions of evolution in the article concerned (1) the researchers calling themselves “evolutionary biologists,” (2) the fact that they work at the Laboratory of Behavioral Ecology and Evolution at the Seoul National University, and (3) their research being published in the Journal of Evolutionary Biology. The abstract of that paper seemed very cautious about inferring evolution, stating: “Our study demonstrates that the evolution of morphological adaptations, such as colour pattern of moths, cannot be fully understood without taking into account a behavioural phenotype that coevolved with the morphology for increasing the adaptive value of the morphological trait.” While this suggests the authors are proposing coevolution of behavior with camouflage, the statement is a backhanded swipe at earlier evolutionary 307 7/7/2015 research that neglected behavior. Peppered Moths Without Evolution 胡椒蛾没有进化 Speaking of moths, Live Science posted an interesting list of “7 Things You Don’t Know About Moths, But Should.” These include their importance as pollinators, their role in the food chain for many other animals, and the males’ ability to smell females from seven miles away. If we could get over the yuck factor, we might even find their caterpillars a nutritious superfood, meeting the minimum daily requirements of several important nutrients. Moths are a sister family to butterflies in the Order Lepidoptera, and share many of the same characteristics. 7/7/2015 308 Peppered Moths Without Evolution 胡椒蛾没有进化 This story underscores the uselessness of evolutionary theory. For decades, evolutionary biologists have strained at moths and swallowed camels. They watched the simple things, like how closely a moth’s wings match tree bark, but ignored the weightier matters of moth complexity. Those little flying things circling the lights in your backyard are astoundingly complex machines: they have compound eyes with hundreds of facets, jointed appendages, digestive systems, reproductive systems, navigation systems, communication systems, flight systems – 7/7/2015 309 all packed within their tiny, lightweight bodies. Peppered Moths Without Evolution 胡椒蛾没有进化 Even tougher on evolutionary theory, they undergo metamorphosis – a complete transformation of body plan three times in their lifecycle: egg to caterpillar, then caterpillar to pupa or chrysalis, then chrysalis to adult flying insect. This is shown exquisitely in Illustra’s beautiful film Metamorphosis, which ends with sound reasons why Darwinism cannot explain these abilities. 7/7/2015 310 Peppered Moths Without Evolution 胡椒蛾没有进化 Yet for decades, evolutionists were obsessed with finding an example of natural selection in one species of moth, whether it landed on light or dark tree trunks. And now we are told by the South Korean researchers that “evolution of morphological adaptations, such as colour pattern of moths, cannot be fully understood without taking into account a behavioural phenotype” – in other words, you cannot just play “Pin the Peppered Moth on the Tree Trunk.” You have to watch what a living peppered moth does after it lands. If Kettlewell had simply kept his grubby evolutionary hands off the moths, he might have found dark moths walking on a light-barked tree trunk looking for a better place to blend in, and vice versa. More likely, the moths would be too smart to land on a high-contrast 7/7/2015 311 surface in the first place. Peppered Moths Without Evolution 胡椒蛾没有进化 Trying to invoke “coevolution” as a magic word is folly. It means that evolutionists have to invoke a second miracle: first, the match between wing coloration and tree trunks, and second, the ability of the moth to actively search out and select a suitable spot for camouflage. What causes that behavior? The researchers have no idea. As usual, they use the futureware escape trick: “more research is needed.” The article said they are clueless: “How do they know how to become invisible? The research team is now trying to answer this question as the next step.” Save a 7/7/2015 312 step: ask a creationist.
