Why Did Humans Lose Their Fur? | Science | Smithsonian Magazine
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. But it turns out we are asking the wrong question at least according to scientists who study human genetics and evolution. For them, the big mystery is why we are so hairless.
I never asked myself this question, but I bet my college girlfriend did.
