When a trait appears in two distinct species that share a common ancestor,this is called
A) divergent evolution.
B) homologous evolution.
C) analogous evolution.
D) convergent evolution.

Question

Quizplus · Accepted Answer

Homologous evolution refers to the development of similar traits in two different species that are descended from a common ancestor. This is in contrast to convergent evolution (D), where similar traits develop independently in two species that are not closely related, and to analogous evolution (C), where two species develop similar traits due to similar selective pressures but not due to a common ancestor. Divergent evolution (A) refers to the development of different traits in two species that shared a common ancestor.
