b) vestigial structures.

c) analogous structures.

d) fossil structures.

11.

What are pseudogenes?

b) shared ancestry.

c) lack of evolutionary relationship.

d) great number of mutations.

13.

Which of the following is best related to homologous structures?

a) coding DNA that evolved simultaneously and isn’t inherited from a common ancestor

b) pseudogenes, since they have to be inherited from a common ancestor

c) proteins that happen to be similar due to selection in similar environments

d) pseudogenes, since they are no longer functional DNA

14.

Which of the following is best related to analogous structures?
