Tools show ancient human diet





Almost two million years ago, early humans began eating food such as crocodiles, turtles and fish – a diet that could have played an important role in the evolution of human brains and our footsteps out of Africa, according to new research.

In what is the first evidence of consistent amounts of aquatic foods in the human diet, an international team of researchers has discovered early stone tools and cut marked animal remains in northern Kenya. The work has just been published in the Proceedings of the National Academy of Science (PNAS).

The researchers found evidence of the early humans eating both freshwater fish and land animals at the site in the northern Rift Valley of Kenya. It is thought that small bodied early Homo would have scavenged the remains of these creatures, rather than hunting for them.
