Text Solution
Verified by ExpertsWhen populations of a species are separated by a physical or geographical barrier, e.g., river, mountains, etc., allopatric speciation (formation of new species) occurs. Only organisms belong to the same species can interbreed to produce viable, fertile offspring. An inter-breeding population of finches became separated geographically, forming two isolated groups, i.e., different species therefore they are unable to produce fertile offsprings.
