Early stone tool making more sophisticated than thought
Researchers at the University of Liverpool (England) have found that long and slender stone tools were made by human ancestors at least a million years ago - nearly twice as long ago as generally thought.
Professor John Gowlett, as a member of an international team based on the University's Department of Archaeology, Classics and Egyptology, is working at Kilombe in Kenya, where he has found a number of hand axe tools that are very long and narrow.
Professor Gowlett said: "Some of the stone tools from Kilombe and other early sites are almost two and a half times as long as broad and there is no way this can occur by accident. They must have been carefully crafted. Usually such slender shapes are found far later in the fine blade tools made by Homo sapiens. As the concentrations of elongate tools are rare on the Kilombe site, they were probably made to carry out tasks of animal butchery or plant preparation which did not occur very often. They show that when the need arose early humans were capable of strikingly sophisticated behaviour."
