Farming, Cheese, Chewing Changed Human Skull Shape

The advent of farming, especially dairy products, had a small but significant effect on the shape of human skulls, according to a recently published study from anthropologists at UC Davis.

Skull models

David Katz measured specific points on human skull bones (top) to create a wire frame model of the skull and jaw (bottom). Blue dashes indicate changes in skull shape from foragers to dairy farmers.

Put another way, our skulls were changed by the invention of cheese.
