Which type of speciation occurred when finches living in different habitats on the same island in the Galapagos stopped mating with each other because they were unable to understand each other’s songs?
A
geographical isolation
B
behavioral isolation
C
temporal isolation
Explanation: 

Detailed explanation-1: -Still other finches have medium-size beaks that can catch and grasp insects. Because they are isolated, the birds don’t breed with one another and have therefore developed into unique species with unique characteristics. This is called allopatric speciation.

Detailed explanation-2: -Answer and Explanation: Darwin’s finches are an example of speciation because they developed specialized beaks dependent on the type of food they ate, adapting to their food source and environment.

Detailed explanation-3: -A major example of allopatric speciation occurred in the Galapagos finches that Charles Darwin studied. There are about 15 different species of finches on the Galapagos islands, and they each look different and have specialized beaks for eating different types of foods, such as insects, seeds, and flowers.

Detailed explanation-4: -Sympatric speciations occurs when species diverge while living in the same geographic habitat. Allopatric speciation occurs when two populations of a species become separated (in this case by a highway), and over time become separate species.
