Question

Quizplus · Accepted Answer

The presence of stone tools, animal bones, and teeth suggests that hominids at Gran Dolina were processing and consuming animals, including other hominids. This indicates a level of carnivory and possibly cannibalism, which is not seen in earlier Homo erectus or australopithecines. While there is no evidence to suggest they were similar to later Homo sapiens, the presence of these tools is an important development in the progression of human evolution.
