Naama Goren-Inbar of Hebrew University and her colleagues discovered burned fragments of flint, wood, fruit and grains at the Gesher Benot Ya¿aqov bridge site in Israel¿s Hula Valley, which dates to 790,000 years ago. Large quantities of unburned flint and wood also dotted the site. The researchers painstakingly mapped the distribution of the tens of thousands of specimens they found and determined that the burned relics clustered together at specific spots, indicating that the site¿s inhabitants were in control of what was burned and where. In addition, only about 2 percent of the flint and 4 percent of the wood samples had been burned. A natural fire, the authors note, would most likely have charred a larger portion of the remains. The new find pushes back the initial date of human exploitation of fire by a quarter of a million years (several sites in Europe suggest that the practice was occurring 500,000 years ago).
The identity of the fire-making inhabitants of the Israeli locale remains unclear, however. According to the report, the proposed fire users may have been Homo erectus, Homo ergaster or archaic Homo sapiens, but it is impossible to associate a particular hominin species with the Hula valley site. Nevertheless, the authors conclude that "the domestication of fire by hominins surely led to dramatic changes in behavior connected with diet, defense and social interaction."
