years ago and Middle Paleolithic Homo sapiens sites at Pinnacle Point, in Africa. Anthropologists such as Tim D. White suggest that cannibalism was common in human societies prior to the beginning of the Upper Paleolithic, based on the large amount of “butchered human" bones found in Neandertal and other Middle Paleolithic sites. Cannibalism in the Middle Paleolithic may have occurred because of food shortages. However it is also possible that Middle Paleolithic cannibalism occurred for religious reasons which would coincide with the development of religious practices thought to have occurred during the Upper Paleolithic. Nonetheless it remains possible that Middle Paleolithic societies never practiced cannibalism and that the damage to recovered human bones was either the result of excarnation or predation by carnivores such as saber-toothed cats, lions and hyenas. Technology Around 200,000 BP Middle Paleolithic Stone tool manufacturing spawned a tool-making technique known as the prepared-core technique, that was more elaborate than previous Acheulean techniques. Wallace and Shea split the core artifacts into two different types: formal cores and expedient cores. Formal cores are designed to extract the maximum amount from the raw material while expedient cores are based more upon functional need. This method increased efficiency by permitting the creation of more controlled and consistent flakes. This method allowed Middle Paleolithic humans correspondingly to create stone-tipped spears, which were the earliest composite tools, by hafting sharp, pointy stone flakes onto wooden shafts. Paleolithic groups such as the Neanderthals who possessed a Middle Paleolithic level of technology appear to have hunted large game just as well as Upper Paleolithic modern humans and the Neanderthals in particular may have likewise hunted with projectile weapons. Nonetheless Neanderthal usage of projectile weapons in hunting occurred very rarely (or perhaps never) and the Neanderthals hunted large game animals mostly by ambushing them and attacking them with mêlée weapons such as thrusting spears rather than attacking them from a distance with projectile weapons. An ongoing controversy about the nature of Middle Paleolithic tools is whether there were a series of functionally specific and preconceived tool forms or whether there was a simple continuum of tool morphology that reflect the extent of edge maintenance, as Harold L. Dibble has suggested. The use of fire became widespread for the first time in human prehistory during the Middle Paleolithic, and humans began to cook their food c. 250,000 years ago. Some scientists have hypothesized that hominids began
