An ecologist studying predators and their prey in White Sand Dunes State Park found that nocturnal pocket mice exist in light and dark morphs. In this area, 42% of the mice are dark, and 58% light. In a study of owls that ate the mice in this area, the ecologist found that 61% of the mice caught by owls were dark, and 39% were light. What is likely to happen to the pocket mouse population in the future and why? Is this evolution?
