Prehistoric human researchers may have undermined other bone, now suggest.
Scientists have long seen evidence of prehistoric cannibalism, such as trademark Boucher on bones. To find out if yes or no cavemen chewed on human bones, the researchers first get a look at this bite marks might look like.
Scientists had volunteers chew bone - those not human, but boiled pork raw ribs and sheep as well as sheep and BBQ pork ribs legs. The bone-gnawers included European and Koi people of Namibia.
Researchers saw patterns in bone spike - including the folded edges, gratin and perforations surface and grooves. They detected brands like bite on bones of 12,000 years of prehistoric man cave Gough in England and the remains of extinct human species Homo antecessor site of Gran Dolina in Spain 800,000 years.
"It helps to give a better idea of what had happened to as the first humans were recolonize Britain after the last glaciation," said paleoanthropologist Briana Pobiner at the Smithsonian Institution, who have not participated in this study. "They could have been under the major constraint on nutritional cannibalism and resources may be an adaptation to it."
Not all these bite marks are unique individuals. Yet, scientists explained that seen in combination, they can provide evidence of erode human.
"It would be really interesting to see if the toothmarks on assemblages prehistoric really early fossil were made by humans, as opposed to carnivorous mammals", Pobiner said LiveScience. "Previous species of homo have chewing muscles much more robust than ours, with a greater capacity to damage in os than we."
Researchers in detail their conclusions in the issue of January, 2011 for the journal of human evolution.
