"The story of Neanderthal extinction is one of the most intriguing in all of human evolution," author Simon Underdown told Discovery News. "Why did a large-brained, intelligent hominid that shared so many traits with us disappear?"
To resolve that question, Underdown, a lecturer in the Department of Anthropology at Oxford Brookes University, studied a well-documented tribal group, the Fore of Papua New Guinea, who practiced ritualistic cannibalism.
Gory evidence uncovered in a French cave in 1999 revealed Neanderthals likely practiced cannibalism. The 100,000-120,000 year-old bones discovered at the cave site of Moula-Guercy near the west bank of the Rhone river suggested a group of Neanderthals defleshed the bones of at least six other individuals and then broke the bones apart with a hammerstone and anvil to remove the marrow and brains.
