This document discusses several key terms related to evolution: Natural selection refers to organisms being better or less suited to survive based on characteristics. Convergent evolution occurs when different species independently evolve similar traits to solve common problems. Divergent evolution happens when a species branches off into multiple forms suited to different environments or food sources. Coevolution is when two dependent species evolve together over time, such as flowers and the insects that pollinate them.

The idea of evolution is a simple one. Things
change. Right now we're just talking about the
word, not the philosophical idea. The process of
cars changing over the past 100 years can be
thought of as an evolution in engineering. When an
organism changes over many generations, it might
be better suited to live, or more likely to die. To
describe what happens, scientists have a few
terms.

3. Natural Selection
We were just talking about that. Sometimes you've got a
skill that helps you survive; sometimes you don't. If you
were a 500 pound bird with little tiny wings and little tiny
legs, chances are you wouldn't move around too well. One
day you might run out of food and die. Oh well, you were
just selected for extinction.

4. CONVERGENT EVOLUTION
This is when two totally different
species develop similar traits. They
have come up with the same solution to
a problem but from different directions.
It's not a conscious choice to develop
an eye or a way of hearing. Outside
natural factors create a situation where
that skill is a benefit.

5. DIVERGENT EVOLUTION
This is when your development starts at one place and splits in
different directions. We start as the same species, but then as more
generations develop, my group becomes good at one thing and
yours at another.
Bird beaks are a good example for this one. One species of bird can
develop in different directions depending on what type of food it
eats. Their beaks develop different shapes after many generations.
Charles Darwin used bird development in many of his scientific
papers.

6. COEVOLUTION
This is when two different species change and evolve
over time together. They are usually dependent on
each other for survival. Flowers and insects are good
examples of this type of coevolution.
If you have seen really fancy orchids, they often
depend on a single species of bug to help them
reproduce. As one species changes, the other will
make mirror changes so that it can continue to
survive.
