Question

Different geographical barriers physically separated the tortoises on the Galápagos Islands. This separation resulted in the evolution of subspecies. This is an example of _____ speciation.

Answer 1

Allopatric

Explanation:

Allopatric or geographic speciation is the speciation that occurs when a population of the same species becomes isolated by a sudden geographical change (for example, after an earthquake, the formation of mountains or rivers). Therefore both populations will evolve differently until they reach a point where they can no longer breed between them.
