Study co-author Professor Ran Barkai from the University’s Department of Archaeology said: “This study was designed to examine a broader unifying hypothesis which explains the cultural and physiological evolution of prehistoric humans.ĭr Ben-Dor added: “Studies of contemporary hunter-gatherers indicate that a wooden spear is quite sufficient for hunting large prey like an elephant. These stone-tipped spears were apparently used for both thrusting and hurling.Ībout 50,000 years ago more complex hunting systems like the bow and arrow and spear thrower, were used regularly by Homo Sapiens.Īt the end of the Upper Paleolithic, about 25,000 years ago, new hunting aids emerged, such as dogs, traps, and fishing hooks. Homo Sapiens and Neanderthals, emerging about 300,000 years ago, upgraded their spears by adding stone tips, which they produced with the more sophisticated Levallois technique. Homo Erectus, the ancestor of all later types of humans, used a wooden spear, probably thrusting it into large prey from up close. imperator, occurring west of the Andes Mountains from Ecuador in northwestern South America northward to Mexico in North America, and including the two subspecies B.
It has been elevated to species status as B.
The team analyzed findings from nine prehistoric sites in South Africa, East Africa, Spain, and France, inhabited during the transition from the Lower to the Middle Stone Age or Paleolithic, about 300,000 years ago, when Neanderthals and Homo Sapiens first emerged. Boa imperator was formerly one of six recognized subspecies of B. “We found that in all cases, at all sites, stone tips made with the Levallois technology appeared simultaneously with a relative decrease in the quantity of bones of large prey.
