Evolution is change in a population over time and includes the gene pools of that population. How does biogeographic isolation allow for the change of gene pools over time?

Biogeographic isolation separates populations geographically, reducing or preventing gene flow between them. Once separated, each population’s gene pool can change independently over time through mutation, natural selection, and genetic drift. Therefore, the correct choice is “Biogeographic isolation causes changes in gene pools that result from populations being separated.”
