Researchers from the Smithsonian's National Museum of Natural History led a new analysis that sheds light on the ancestry and genetics of woolly dogs, a now extinct breed of dog that was a fixture of Indigenous Coast Salish communities in the Pacific Northwest for millennia. Anthropologist Logan Kistler and evolutionary molecular biologist Audrey Lin analyzed genetic clues preserved in the pelt of "Mutton," the only known woolly dog fleece in the world, to pinpoint the genes responsible for their highly sought-after woolly fur.
