The Finches of the Galápagos Islands Evolved as a Result

Multiple Choice

The finches of the Galápagos islands evolved as a result of what types) of speciation?

A) allopatric speciation
B) adaptive radiation
C) sympatric speciation
D) both allopatric speciation and adaptive radiation
E) both sympatric speciation and adaptive radiation The Galápagos finches are usually presented as an example of adaptive radiation, a mechanism by which multiple species arise from a common ancestor. However, the speciation of the finches also involves allopatric speciation, in which the reproductive isolation of populations of finches resulted in their speciation. Thus, the speciation of finches in the Galápagos reflects both adaptive radiation and allopatric speciation.
