Detailed explanation-1: -Speciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge. In allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation.

Detailed explanation-2: -The process of development of a new species by evolution or by any genetic modification of the existing species in a population is called as speciation. Factors that lead to speciation include genetic drift, natural selection, geographical isolation, mutation.

Detailed explanation-3: -Species and Allopatric Speciation 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.
