Sophia Estes · Answer 1

It is likely that the emergence of geographical barriers among populations (such as for example, rivers, mountains, etc.) were responsible for the isolation of these species.

Explanation:

The presence of geographical barriers among populations ensure that they begin to evolve independently and mechanisms of reproductive isolation will appear among them

Luka Boyd · Answer 2

They will evolve independently.

Explanation:

Allopatric speciation is also known as geographical speciation. It is a type of speciation that happens when there is the isolation of the same species of organism within a population from one another which gets to a level in which it affects their gene flow. This isolation is as a result of geographical changes like, shifting of the continents, mountain building, it could also be due to social changes like emigration.
