Edwin is studying a population of rabbits in the neighborhood that surrounds his home. He observes a variety of fur colors among the rabbits, including gray, white, and brown. The rabbit fur also has a variety of markings, including spots and bands.

Mutations are natural processes that can increase genetic diversity.
Mutations are unnatural processes that are always harmful to genetic diversity.
