Question

Quizplus · Accepted Answer

Ecological isolation, where geographic barriers create different environments that lead to divergent natural selection, is the most closely related to allopatric speciation. Allopatric speciation occurs when biological populations of the same species become isolated from each other due to geographic barriers, leading to genetic divergence and ultimately new species. This can be facilitated by ecological differences and natural selection acting on divergent environments. Temporal isolation, mechanical isolation, behavioral isolation, and genetic isolation may also contribute to the evolution of new species in allopatric populations, but they are not as closely related to allopatric speciation as ecological isolation.
