A species is a group of organisms capable of mating and producing 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.
