Humans Still Have The Genes For a Full Coat of Fur, Scientists Discover : ScienceAlert
Fur is a defining feature of being a mammal. But bald is beautiful for several mammalian weirdos, including dolphins, mole rats, elephants, and of course, humans. Not to mention a handy adaptation.Yet all our ancestors had plenty of fur. According to a new study on relatively hairless mammals, we still have the means to be hirsute. Those genes, it seems, have simply been switched off.In their hunt through nearly 20,000 coding genes, and 350,000 regulatory ones, compared across 62 different mammal species, University of…
