In particular, a recent study in the journal Cell Reports has begun to depilate the mystery at the molecular and genetic level. #Hairless gorilla skinDid we adapt to semi-aquatic environments? Does bare skin help us sweat to keep cool while hunting during the heat of the day? Did losing our fur allow us to read each other's emotional responses such as fuming or blushing? Scientists aren't exactly sure, but biologists are beginning to understand the physical mechanism that makes humans the naked apes. For them, the big mystery is why we are so hairless.Įvolutionary theorists have put forth numerous hypotheses for why humans became the naked mole rats of the primate world. ![]() But it turns out we are asking the wrong question-at least according to scientists who study human genetics and evolution. Millions of modern humans ask themselves the same question every morning while looking in the mirror: Why am I so hairy? As a society, we spend millions of dollars per year on lip waxing, eyebrow threading, laser hair removal, and face and leg shaving, not to mention the cash we hand over to Supercuts or the neighborhood salon. ![]()
