he loss of body hair is one of the most distinctive features of the human species. Among the great apes, humans are the only truly hairless primates, an evolutionary mystery that touches on genetics, climate, cognition, and culture. While modern humans retain hair on the scalp, the rest of the body is sparsely covered compared to our primate cousins.
