We’ve been getting human nature wrong for 100 years

ONE day in the summer of 1924, an anthropologist named Raymond Dart made an incredible discovery – and drew a conclusion from it about human nature that would mislead us for a century.

Dart was examining a set of fossils that had been unearthed by miners near the town of Taung in South Africa when he found the skull of a “missing link” between ancient apes and humans. It belonged to a juvenile member of the species Australopithecus africanus who was later nicknamed the Taung Child.

The skull conclusively demonstrated that Africa was the birthplace of humankind. It also seemed to reveal something sinister about human nature: There was a series of grooves etched in the bone, which Dart believed could be produced only by human-made tools. These marks convinced him that this young hominid had been butchered and eaten by another member of its tribe (perhaps a hungry uncle).
