Rock pocket mice live in the deserts of the American southwest. Ancestral pocket mice all had light-colored coats that blended in
with the region's rocks and sandy soil, keeping the mice hidden from predatory owls. About 1.7 million years ago, a series of
volcanic eruptions spewed out wide trails of black lava into the middle of rock pocket mouse territory. Currently there are two color
morphs of rock pocket mice: light-colored mice that are typically found in habitats with sandy soil, and dark-colored mice that are
typically found in habitats with dark-colored lava rocks.
