Allopatric speciation occurs when a population is physically divided, leading to new species through adaptive radiation, as evidenced by Darwin's finches on the Galápagos Islands.
Allopatric speciation occurs when a population of one species is physically divided into isolated subpopulations, leading to different selection pressures and eventual divergence, resulting in new species. One example of this is seen in the finches studied by Darwin on the Galápagos Islands, where a single seed-eating bird species evolved into multiple finch species adapted for different food sources, showcasing adaptive radiation.
