Answer:

Answer is D

The isolation of the two groups in different environments

Explanation:

Two separate species inhabit the north and south rims of the canyon. The Kaibab squirrels inhabit the north rim and the Albert squirrels inhabit the south rim. The Kaibab squirrel became geographically isolated from the common ancestor with its closest relative, the Albert squirrel in the North Rim of the Grand Canyon about 10,000 years ago.
