BARCELONA, SPAIN—Ten volunteers used only their hands and teeth to eat raw, roasted, and boiled lamb for a study led by Antonio J. Romero of the University of the Basque Country. According to a UPI report, the scientists then analyzed the marks left on the 90 lamb bones, and found that men left more marks than women, but the marks themselves were indistinguishable. Tooth marks appeared more regularly in the bones of meat that had been roasted or boiled. Raw bones had more damage on the tips and edges, and tended to be crushed more often. The study will help archaeologists distinguish between bones gnawed on by hominins and those left behind by other carnivores who may have visited sites used by early hunter-gatherers.
