Question

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 affects the random changes that take place within gene pools.
biogeographic isolation causes changes in gene pools that result from populations being separated.
biogeographic isolation determines who will win competition for mates.
biogeographic isolation determines the time that populations will breed.

Explanation:

Biogeographic isolation refers to the physical separation of populations (e.g., by mountains, oceans). When populations are separated, gene flow between them stops. Over time, each isolated population accumulates unique genetic changes (due to mutation, natural selection, etc.), leading to divergence of their gene pools. The correct option directly links this separation to gene pool changes.

Answer:

Biogeographic isolation causes changes in gene pools that result from populations being separated.
