Early Fire Use Ignites Discussion about the Evolution of Human BrainpowerAugust 13, 2009
New evidence that early modern humans used fire in southern Africa in a controlled way to increase the quality and efficiency of stone tools is changing how researchers understand the evolution of human behavior, and in particular, the evolution of human brain power.
Curtis Marean and Kyle Brown, both paleoanthropologists with the Institute of Human Origins at Arizona State University, and an international team of researchers with members from South Africa, England, Australia and France found 72,000-year-old, silcrete rocks that had been fired and flaked to make stone tools in a cave along the coast of the southern tip of Africa in Mossel Bay.
