Pushing the timeline of early humans, scientists uncover shocking evidence of possible cannibalism from 1.45 million years ago. An age-old tibia with neat slashes tells a chilling tale of survival. Paleoanthropology HumanEvolution
Pobiner was less interested in resolving this decades-long dispute than in confirming that the slashes came from a stone tool. Doing so meant making use of a special database of bone marks and injuries, so she made impressions of the slashes along with two others that likely came from animal teeth. She sent the molds to Michael Pante, a paleoanthropologist at Colorado State University, along with no information as to their origins or her suspicions.
Pante scanned in the molds and compared them against a database of about 900 other examples of bones injured by tools, trampling and carnivores. The database confirmed Pobiner’s early conclusions and further proposed that a large cat, maybe even a saber tooth tiger, had made the two teeth marks. Whether the animal left the two marks before or after the hominin died, the researchers couldn’t say.
