Allopatric speciation Explanation

An example of allopatric speciation is the water level in a lake that subsides, resulting in two or more smaller lakes that are now home to separated populations. Or a river may change course and divide a population of animals that cannot cross it. Allopatric speciation can also occur without geologic remodeling, such as when individuals colonize a remote area and their descendants become geographically isolated from the parent population.
