London, June 19 (ANI): In a new research, a pair of scientists has suggested that weapons like spears, and a bow and arrow, go back as far back as 100,000 years ago, predating modern humans.
According to a report in New Scientist, the research was done by Matthew Sisk and John Shea from Stony Brook University in New York.
They say that simple stone blades make adequate arrowheads; so they might have been used in lightweight projectile weapons as far back as 100,000 years ago, when the blades first appeared.
Spears and arrows would have let early hunters catch small fast-moving creatures rather than tackling large dangerous animals with hand-held blades.
Matthew Sisk and John Shea have shown that so-called Levallois points make effective arrowheads.
They turned 51 reproduction blades into arrows and successfully shot them into an animal carcass
The earliest definite arrowheads date to around 20,000 years ago and are the handiwork of modern humans. (ANI)
