Does geographical isolation of individuals of a species lead to formation of a new species? Provide a suitable explanation. 

Answers (1)

Yes, the geographical isolation of individuals of a species leads to the formation of a new species.
Reproductive isolation is caused by the splitting of existing species into two new species followed by their geographical isolation. This separation is done by the accumulation of genetic variations. The newly formed groups are isolated by geographical barriers. This in turn, prevents interbreeding between members of different species.

Hence this causes the isolation of the gene pool of a section of the population from rest and leads to the formation of new species.
