Several finches from the mainland of South America fly to a Pacific Island archipelago and colonize the first island they get to.Over time,individuals on this island fly to a nearby island and colonize it.This process occurs repeatedly and over evolutionary time each colonizing bird becomes its own species due to distinct ecological and environmental processes taking place on each island.What type of speciation best describes this example?

Question

Quizplus · Accepted Answer

The scenario described in the question is an example of allopatric speciation. Allopatric speciation occurs when a population becomes geographically isolated from its parent population and evolves into a distinct species over time due to different environmental and ecological factors. In this case, the colonization of different islands by the finches led to the isolation and subsequent evolution of distinct species on each island.
