Prehistoric Stone Tools Bear 500,000-Year-Old Animal Residue
Some 2.5 million years ago, early humans survived on a paltry diet of plants. As the human brain expanded, however, it required more substantial nourishment - namely fat and meat - to sustain it. This drove prehistoric man, who lacked the requisite claws and sharp teeth of carnivores, to develop the skills and tools necessary to hunt animals and butcher fat and meat from large carcasses.

The world's earliest sophisticated stone tools have been found near Lake Turkana in northwest Kenya. The teardrop-shaped hand-axes date to about 1.76 million years ago, and would have been used for a range of tasks from chopping wood to cutting up meat. They would have been so useful in fact that scientists describe them as the "Swiss army knife" of the Stone Age. Read more
The discovery of stone axes in the same sediment layer as cruder tools indicates that hominins with differing tool-making technologies may have coexisted. The axes, found in Kenya by Christopher Lepre, a palaeontologist at Columbia University in New York, and his team are estimated to be around 1.76 million years old. That's 350,000 years older than any other complex tools yet discovered. Read more
Ancient humans fashioned hand axes, cleavers and picks much earlier than believed, but didn't take the stone tools along when they left Africa, new research suggests. A team from the United States and France made the findings after travelling to an archaeological site along the northwest shoreline of Kenya's Lake Turkana. Two-faced blades and other large cutting tools had been previously excavated there along with primitive stone flakes. Read more
The stone tools, known collectively as Acheulian tools, are believed to be the handiwork of the human ancestor Homo erectus. Read more
