Question

a species is a group of organisms capable of mating and producing fertile offspring, and speciation is the process of forming a new species.
one way a new species may form is by geographic isolation. this occurs when members of a population are physically separated, for example, by a river, or a desert.
after the separation the two populations, responding to different conditions, will adapt differently, and so their evolutionary paths will
a converge.
b dissect.
c diverge.
d reverse.

Explanation:

The text describes geographic isolation leading to new species. When separated populations adapt to different conditions, their evolutionary paths become distinct. "Diverge" means to separate or become different, which matches this process.

Answer:

C. diverge
