Chapter 8 - Forms of evolution

Question 1

What are homologous structures?

Answer 1

similar basic structures, different specific functions

Question 2

What are analogous structures?

Answer 2

When very distantly related species develop similar adaptations.
Different basic structures, similar specific function

Question 3

What is divergent evolution?

Answer 3

It occurs when one ancestral species evolves into one or more new species

Question 4

What is another word for divergent evolution?

Answer 4

Adaptive radiation

Question 5

Which structure is a result of divergent evolution?

Answer 5

Homologous structures

Question 6

How does a population evolve into one or more species?

Answer 6

The offspring adapts in slightly different ways to the original population

Question 7

What is convergent evolution?

Answer 7

This occurs when two unrelated species evolve similar adaptations to suit their similar environments

Question 8

What is an example of convergent evolution?

Answer 8

Flying squirrel and sugar glider

Question 9

Does divergent evolution have a common ancestor?

Answer 9

Yes

Question 10

Does convergent evolution have a recent common ancestor?

Answer 10

No, it involved two unrelated species
