Black wolf

Genetic research has shown that black-furred wolves owe their coloration to a mutation that first arose in domestic dogs. (photo taken in Yellowstone National Park)

A black wolf is a melanistic colour variant of the gray wolf (Canis lupus).[1][2] Black specimens were recorded among red wolves (Canis rufus), though the colour phase in this species is not extinct yet.[3] Genetic research from the Stanford University School of Medicine and the University of California, Los Angeles revealed that wolves with black pelts owe their distinctive coloration to a mutation which occurred in domestic dogs, and was carried to wolves through wolf-dog hybridization.[1] Besides coat and knee colour, they are normal grey wolves.
