Question

a population of orioles from a west coast species and an east coast population of orioles migrate to the midwest.they create a new home range and a hybrid cross of both species eventually develops. this is an example of which form of speciation?
spontaneous speciation
parasympatric speciation
allopatric speciation

Explanation:

Allopatric speciation occurs when a population is separated by a geographical barrier. In this case, the West - coast and East - coast orioles were likely separated originally (allopatric), but when they migrate to the Midwest and hybridize, the key point is that the initial separation (allopatric) led to genetic differences that now allow for hybridization in a new area. Spontaneous speciation is not a standard recognized form in the context of the main speciation models. Parapatric speciation is about adjacent populations with a narrow hybrid zone without a full - scale geographical separation like in allopatric.

Answer:

Allopatric Speciation
