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

Open in App

Solution

Yes, geographical isolation gradually leads to genetic drift. This may impose limitations on sexual reproduction of the separated population. Slowly the separated individuals will reproduce among themselves and generate new variations. Continuous accumulation of those variations through a few generations may ultimately lead to the formation of new species.
