The Big Question: Why Does Hair Grow in Some Places But Not Others?

TWEEZE, SHAVE, CHEMICAL cream, wax or electro-zap: Humans have come up with a pharmacy’s worth of ways to deforest their bodies of natural hair.

Yet, to evolutionary biologists, humans are amazing not because they have so much hair, but because they have so little. Whereas our ancestors once sported full-fur suits, Homo sapiens today are almost embarrassingly naked.

The story of how our bodies morphed from being upholstered in head-to-toe carpeting into a mosaic of hairy and non-hairy bits is one of sweat, sex, scent, and (not to be left out) climate change.
