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.
The different mechanisms of reproductive isolation are genetically controlled and it has been demonstrated experimentally that they can evolve in species whose geographic distribution overlaps (sympatric speciation) or as the result of adaptive divergence that accompanies allopatric speciation.ny of the factors that prevent potentially fertile individuals from meeting will reproductively isolate the members of distinct species. The types of barriers that can cause this isolation include: different habitats, physical barriers, and a difference in the time of sexual maturity or flowering.
