At the edge of the Arctic Circle, owls prey on field mice. Occasionally, in a litter of white field mice, a brown mouse appears. Because of greenhouse warming, the snow melts, changing the environment to shades of brown. The adaptations which allow survival and reproduction of a certain color of mice in the new environment is due to:     variation.     lethal mutations.     acquired traits.     isolation.
