Texas Science Curriculum Director Canned for
Mentioning Evolution
A Texas science education official
Christine Comer, Science
Director
Texas Education Agency
forced to resign in October wasn’t — as her
bosses inisted — fairly punished for
insubordination. Her real crime: daring to tell
people about a lecture critical of intelligent design.
The Austin-American Statesman
reported last week that science curriculum
director Chris Comer’s ouster followed her
circulation of an email announcing an upcoming
speech by Barbara Forrest, co-author of
Creationism’s Trojan Horse: The Wedge of
Intelligent Design and an expert witness in
Kitzmiller v. Dover. That lawsuit was brought in
2005 by Dover, Pennsylvania parents upset with
a school board’s decision to teach intelligent
design — the belief that some phenomena can
only be explained as divinely manufactured — as
a scientific theory comparable to evolution.

Wild Dogs Kill 4-H Lambs
In Wheelersburg, Ohio, Monday morning, five 4-H future prize winning
lambs -- potentially worth a lot of money -- were killed by a pack of wild dogs.
Middle and high school 4-H members came home from school to blood and
broken hearts.
