5. The mechanism for evolution is natural selection. Traits become more or less common in a population depending on whether they are beneficial or harmful.
An example of evolution by natural selection can be found in the deer mouse,
species Peromyscus maniculatus. In Nebraska this mouse is typically brown, but
after glaciers carried lighter sand over the darker soil in the Sand Hills, predators
could more easily spot the dark mice. Natural selection favored the light mice,
and over time, the population became light colored. What was the environmental
change that resulted in a change in the deer mouse?
O A. The Ice Age
O B. Environment changed color
O C. Became colder
O D. No change
