Detailed explanation-1: -Allopatric speciation (1) occurs when a species separates into two separate groups which are isolated from one another. A physical barrier, such as a mountain range or a waterway, makes it impossible for them to breed with one another.

Detailed explanation-2: -The physical separation of members of a population. populations may be physically separated when their original habitat becomes divided. Example: when new land or water barriers form. See also allopatric speciation.

Detailed explanation-3: -Geographical isolation means the separation of species by physical barriers like water forms, oceans, mountains, etc. The organisms are ultimately separated from exchanging genetic material with other organisms of the same species.

Detailed explanation-4: -Allopatric speciation, also known as geographic speciation, is speciation that occurs when biological populations of the same species become isolated due to geographical changes such as mountain building or social changes such as emigration.
