Insight into competitive advantage of modern humans over Neanderthals
(PHYSorg.com Archaeology & Fossils)

A team of Japanese and Italian researchers, including from Tohoku University, have evidenced mechanically delivered projectile weapons in Europe dating to 45,000-40,000 years-more than 20,000 years than previously thought. This study, titled `The earliest evidence for mechanically delivered projectile weapons in Europe,` published in Nature Ecology & Evolution, indicated that the spearthrower and bow-and-arrow technologies allowed modern humans to hunt more successfully than Neanderthals-giving them a competitive advantage. This discovery offered important insight to understand the reasons for the replacement of Neanderthals by modern humans.
