African Arrow Origins

"'I think the finding adds to growing evidence for the great antiquity
of complex projectile weaponry in Africa,' says paleoanthropologist
John Shea of Stony Brook (N.Y.) University. 'The real startling upshot
of this finding is that it challenges longstanding archaeological
beliefs that important changes in projectile technology only occurred
very recently, less than 30,000 years ago, after humans dispersed into
Europe.'"
