Prehistoric humans may have practiced brain surgery on cows


Humans have been performing brain surgery—or at least drilling holes in one others’ skulls—for thousands of years. But how did they get their practice? A new study analyzing an exquisitely bored hole in the skull of a 5000-year-old cow (above) suggests they may have honed their skills on animals.

The bovine cranium in question was found in Vendée, France, a Neolithic site that was a trade hub for salt and cattle between 3400 and 3000 B.C.E. Scientists originally thought the cranial hole came from a traumatic blow by another cow, but others suspected a human hand at work.
