D) populations are separated by a distance that is great enough to limit gene flow.

Question

Quizplus · Accepted Answer

Geographical isolation occurs when populations are separated by a distance that is great enough to limit gene flow. This can occur due to physical barriers such as mountains, bodies of water, or other obstacles that prevent individuals from moving between populations. In this way, genetic differences can accumulate between populations over time, leading to the evolution of new species.
