Gene gives mice and chipmunks their pinstripes
Biologists identify new molecular pathway behind mammalian fur patterns
ARTIST IN RODENTS African striped mice (one shown munching on a thorn tree) evolved a new trick for an old protein. The protein ALX3, which helps direct development of bones and cartilage in the face, also paints light stripes down the rodents’ backs, a new study suggests. Chipmunks independently evolved the same pinstriping method.

Chipmunks and other rodents’ light stripes are painted with a recycled brush, a new study suggests.
