Prehistoric People Ate Each Other
Prehistoric humans, along with Neanderthals and Homo antecessor, made meals of each other, suggests new research on human teeth marks found on prehistoric human bones.
The findings of a new study, which will be published in the January issue of The Journal of Human Evolution, support prior theories that the first humans to re-colonize Britain after the last ice age practiced nutritional cannibalism 12,000 years ago at a site called Gough's Cave in what is now Somerset, England. It was a survival strategy, according to authors Yolanda Fernandez-Jalvo and Peter Andrews. "Think that a member of your group dies," Fernandez-Jalvo told Discovery News. "The body can give one day off from hunting, which was always dangerous at that time, and what to do with the dead body that may attract other dangerous carnivores that may attack the group."
