Archaeologists have found stone tools in Kenya that were used by hominids and are up to 2.9 million years old. That reports the BBC. They are among the oldest stone tools ever found.
The find proves that primitive tools were used not only by the ancestors of Homo Sapiens, but also by other hominids.
The tools were used, among other things, to butcher hippos and to grind plants and tubers, scientists said.
Paranthropus
Teeth found at the Nyayanga site in western Kenya belong to Paranthropus, an extinct cousin of the ancestors of modern humans. Scientists always assumed that stone tools were only used by the ancestors of Homo Sapiens. But no fossil remains of Homo Sapiens were found at the site, only fossil molars of Paranthropus and some 330 stone tools.
