Question 1

Parapatric speciation occurs when

Accepted Answer

A)  selection causes a single species to develop different adaptations to a similar environment. 
B)  a population is divided into two reproductively isolated subgroups that form separate species. 
C)  a single species experiences a gradient of environmental differences within its geographic range, which result in partial genetic isolation. 
D)  a formerly isolated subpopulation recolonizes its home range and mates with the remaining individuals.
