a species is a group of organisms capable of mating and producing offspring, and speculation 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.
