C

Assume there are two varieties of mice, brown and gray, living on an island. They are the prey for the hawks on the island. They are distributed through rocky areas in the north of the island and across the fields in the south part. Which of the following is predicted by natural selection?

A) Hawks find the mice by movement so it won't matter.B) If they stay as a mixed population, they will remain mixed

because the two varieties will not interbreed with each other.

C) Since brown mice blend better with the ground and gray mice blend better with the rocks, these are the ones that will be missed by the hawks and the mouse distribution will tend to indicate this.

D) A mouse population that starts as a random mixture will never adapt to the environment.

E) The hawks will starve to death because they get confused.
