Man hunted with spears half million yrs ago - The Nation

MAN began hunting with stone-tipped spears half a million years ago - 200,000 years earlier than previously thought, according to a new study.
Scientists have discovered our ancestors began hunting with stone-tipped spears 500,000 years ago - with the help of a special crossbow and a dead springbok. Up until recently, it was thought attaching a stone tip to a spear - known as 'hafting' - started about 300,000 years ago.
However, by comparing the wear visible on 500,000-year-old stone points found in South Africa with modern experimental points fired by a specially calibrated crossbow at a springbok carcass, scientists proved they had been used as spear tips for hunting.
'Hafting' was an important technological advance that made it possible to handle or throw sharp points with much more power and control.
Leader author Jayne Wilkins, a PhD candidate in the Department of Anthropology at the University of Toronto in Canada, said the research suggested stone-tipped spears could have been in use before the divergence of early humans and Neanderthals.                             –MO
