Cannibalism is not unusual in the animal kingdom, but the closer the practice gets to Homo sapiens, the more complex and uncomfortable the questions it raises.
“This behavior connects us to our animal nature and reminds us that we are just one among millions of living beings that have existed throughout evolution,” said Antonio Rodríguez-Hidalgo, a postdoctoral researcher at the Catalan Institute of Human Paleontology and Social Evolution who did not participate in the study but took part in a recent workshop on human cannibalism in prehistory entitledcarries deeper philosophical implications.
She forwarded the impression to one of the study’s co-authors, Michael Pante, of Colorado State University, telling him nothing about what it was taken from. Over the course of months, Pante used the impression to make 3D computer models of the marks, which were all between 1 and 5 millimeters long. The models were compared with a database of 898 individual tooth, butchery and trample marks that had been created through controlled experiments.
No stone tools were found with the bone, though Pobiner said tools have been discovered at various dig sites, including one about 15 miles away.Because the cut marks and tooth marks do not overlap, the story of what precisely happened is unclear.
