Allopatric (Greek allos, other, and Latin patria, homeland) populations or species live in separate geographical areas, divided by a barrier such as a mountain range or sea. Allopatric speciation, through such isolation, is the commonest route to new species.
Sympatric species share the same area. Ecological equivalents are unrelated species filling the same niche in different regions, and ecotypes are genetically distinct local forms of a single species adapted to their habitat.
