Evidence of possible human control of fire, found at Swartkrans, South Africa, [21] includes burned bones, including ones with hominin-inflicted cut marks, along with Acheulean and bone tools. [1] This site shows some of the earliest evidence of carnivorous behavior in H. erectus. A "hearth-like depression" that could have been used to burn ...
