Evidence for Evolution

Question 3 • AFC AP Biology B5

How do analogous structures support the pattern of convergent evolution?

Answer
A
They show how organisms change due to genetic variation over time.
B
They prove that physical features of organisms evolved from a common ancestor.
C
They show how similar selective pressures create similar adaptive traits in unrelated organisms.
D
They prove that all organisms naturally develop advantageous features to improve survival and reproductive rates.

Explanation

Analogous structures have similar functions but evolved independently in different groups of organisms. They support convergent evolution because unrelated organisms can face similar environmental pressures and develop similar adaptations. They do not show that the organisms inherited the features from a common ancestor, as choice B suggests.
