Where would you expect to find the most complex (Most evolved) organisms?
What is near the top of the fossil record?
200
What does it indicate that the embryo of a chicken looks much different than the embryo of the human.
What is they are not closely related? (they do not share a recent common ancestor)
200
Certain species of the coral-like sea organisms called bryozoans first appeared about 140 million years ago. They remained unchanged for the first 40 million years and then suddenly experienced rapid genetic change.
Which process would BEST account for the pattern of evolution in bryozoans?
What is abrupt appearance? (punctuated equilibrium)
300
Body parts in different species that have similar functions but are structuraly different.
What are analogous structures?
300
A crocodile arm has the same bones and a similar structure to the human arm. This shows that they....

What type of evolution is represented by the graph below:
What is gradualism?

Theory of evolution that states that there are long periods of stasis until an ecological change occurs that forces rapid evolution of a species.
What is Aprupt Appearence? (Punctuated Equilibrium)

Two contrasting theories of evolution explain changes in species found in fossil records. Gradualism was proposed by Charles Darwin, and punctuated equilibrium was more recently proposed by Niles Eldridge and Steven J. Gould.
The characteristics of gradualism would include -
