Boggs, in International Encyclopedia of the Social & Behavioral Sciences, 2001 3.2 Parapatric Speciation 'Parapatric' derives from 'para' meaning 'near' and 'patria' meaning 'country.' Parapatric speciation thus occurs when a smaller population is isolated, usually at the periphery of a larger group, and becomes differentiated to the point of becoming a new species.

HS-LS4-iv Construct an explanation based on evidence for how natural selection leads to adaptation of populations.HS-LS4-five Evaluate the evidence supporting claims that changes in environmental conditions may result in: (ane) increases in the number of individuals of some species, (ii) the emergence of new species over time, and (3) the extinction of other species. Biologists often divide the ways that speciation can occur into two broad categories: Let's take a closer look at these forms of speciation and how they work. Each finch species became isolated on its own island, which resulted in each island having a unique species.
