Deer Mice

Caption

As the result of natural selection for crypsis, deer mice (Peromyscus maniculatus) living on the pale soils of the Nebraska Sand Hills are lighter (top) than deer mice from darker, surrounding areas (bottom). Mice are shown on contrasting soil backgrounds (bottom: Sand Hills soil; top: soil from outside the Sand Hills).
