Convergent Evolution, Divergent Evolution and Speciation

WebDivergent evolution or divergent selection is the accumulation of differences between closely related populations within a species, sometimes leading to speciation.Divergent evolution is typically exhibited when two populations become separated by a geographic barrier (such as in allopatric or peripatric speciation) and experience different selective … WebSpeciation is the process by which new species form.
