Eating Meat Made Us Human
Anthropologists have found evidence that meat was essential for the survival of our ancestors, over one and a half million years ago. Say anthropology researchers at the University of Colorado, meat eating has always been considered one of the things that made us human, with the protein contributing to the growth of our brains. Research shows that 1.5 million years ago we were not opportunistic meat eaters, we were actively hunting and eating meat. A skull fragment from a 2-year-old child, found at the Olduvai Gorge in Tanzania, shows characteristic bone changes associated with iron-deficiency anaemia caused by a diet suddenly lacking in meat. This indicates that by the early Pleistocene, meat was already essential for human evolution.
