A species of small lizard has three color forms, pale gray, brown, and black. In its original range, the colors of the rocky environment were mixed from pale gray to very dark, and the population had an even mix of all three color forms.

Eventually, the brown lizards disappeared. This is an example of A. directional selection. B. artificial selection. C. stabilizing selection. D. diversifying selection. E. mutation.
