Geographical isolation

Vedclass · Answer

(A) Speciation is the evolutionary process by which populations evolve to become distinct species. Geographical isolation is considered the most critical factor in allopatric speciation. When a population is physically separated by geographical barriers (such as mountains,rivers,or oceans),gene flow between the groups is restricted. Over time,these isolated populations undergo independent genetic changes due to mutations,natural selection,and genetic drift,eventually leading to reproductive isolation and the formation of a new species.
