Why does geographic isolation cause speciation? An example of a separated population to geographic isolation are the American finches that migrated to the Hawaiian islands. From this original finch population, 23 new species of honeycreepers are evidence of speciation due to geographic isolation.
Allopatric speciation (from the ancient Greek allos, other + Greek patris, fatherland) or geographic speciation is speciation that occurs when biological populations of the same species become vicariant, or isolated from each other to an extent that prevents or interferes with genetic interchange.he extent to which a geological barrier can effectively isolate a population correlates to the mobility of the organism or its offspring. For example physical barriers such as canyons may effectively block migration and dispersal of small mammals; however, have little impact on flying birds or wind-borne seeds.
