The finds could shed light on a turning point in the development of culture "in which humans first began to regularly use fire both for cooking meat and as a focal point - a sort of campfire - for social gatherings," said archaeologist Ruth Shahack-Gross of the Weizmann Institute of Science in Israel. "They also tell us something about the impressive levels of social and cognitive development of humans living some 300,000 years ago," Shahack-Gross added in a statement.
The centrally located fire pit is about 6.5 feet (2 meters) in diameter at its widest point, and its ash layers suggest the hearth was used repeatedly over time, according to the study, which was detailed in the Journal of Archaeological Science on Jan. 25. Shahack-Gross and colleagues think these features indicate the hearth may have been used by large groups of cave dwellers. What's more, its position implies some planning went into deciding where to put the fire pit, suggesting whoever built it must have had a certain level of intelligence.
