Fig. 3From: Views from Understanding Evolution: Parsimonious Explanations for Punctuated PatternsA hypothetical example of allopatric speciation. Fruit flies from a mainland population are carried to an island in a hurricane. They evolve in isolation on the island and evolve genetic differences from the mainland population. Eventually, the island population evolves into a distinct species, which no longer mates with members of the mainland speciesBack to article page
