Why classify?
Say you have only 10 minutes to run into a supermarket to
get what you needed. Could you do it?
You would probably head straight to the area where the
items were located.
But what if you had to shop for the same items in a market
where things were randomly placed throughout the
store. Where would you begin? You would have to
search through a lot of things before you found what you
needed! You could be there for a long time!
Biologists have organized living things with similarities into
groups so that the organisms are easier to study. This
process is called classification.
WHAT TO SEARCH FOR

Understanding Classification

Imagine a room filled with people from the province of Buenos Aires.
(KINGDOM)
 There may be some people from the northern area.
(PHYLUM)
 There may be some people who live within 60 km from downtown.
(CLASS)
 There may be some people from your district, e.g. San Isidro.
(ORDER)
 There may be some people from your locality, e.g. Martínez
(FAMILY)
 There may be some people that live on your street.
(GENUS)
 You will be the only one that lives in your house.
(SPECIES)
The more levels you share with others, the more you have in common.
KINGDOMS

Any grouping of organisms into kingdoms is
based on several factors. Find out how the
kingdoms are sorted out.
