The change in the mean is a key feature of directional selection. These mechanisms can lead to each subpopulation becoming so different, that they can no longer interbreed and are considered separate species. natural selection increases reproductive isolation. Presumably, students volition realize that allopatric relies mainly on geographic isolation, but sympatric requires other mechanisms, such equally timing, behaviors, or niche choice.

Each finch species became isolated on its own island, which resulted in each island having a unique species. See, Modes of speciation "The key to speciation is the evolution of genetic differences between the incipient species. Speciation is a slow process due to which populations evolve into different species. Speciation by polyploidy is common in plants but rare in animals. For a lineage to split once and for all, the two incipient species must have genetic differences that are expressed in some way that causes matings between them to either not happen or to be unsuccessful.

The flies that were born in apples tended to feed on apples and mate with other flies on apples, while the flies born on hawthorns tended to similarly stick with hawthorns, Over time, the population diverged into two genetically distinct groups with adaptations, features arising by natural selection, that were specific for apple and hawthorne fruits. 5.0 (4) $2.00. Boggs, in International Encyclopedia of the Social & Behavioral Sciences, 2001 3.2 Parapatric Speciation 'Parapatric' derives from 'para' meaning 'near' and 'patria' meaning 'country.'
