A skull fragment unearthed by anthropologists in Tanzania shows that our ancient ancestors were eating meat at least 1.5 million years ago, shedding new light into the evolution of human physiology and brain development.
“Meat eating has always been considered one of the things that made us human, with the protein contributing to the growth of our brains,” said Charles Musiba, Ph.D., associate professor of anthropology at the University of Colorado Denver, who helped make the discovery. “Our work shows that 1.5 million years ago we were not opportunistic meat eaters, we were actively hunting and eating meat.”
