COVER Beach mice (Peromyscus polionotus) have recently colonized the white sandy beaches of Florida's Gulf Coast, where they have evolved a novel coat color pattern that camouflages them from predators. In a Report on page 1062, Manceau et al. show how small changes in the level and location of expression of a single gene in the mouse embryo cause large changes in adult color pattern.
