A later study of the cave in 2009 found evidence that early modern humans used fire in a controlled way to increase the quality and efficiency of stone tools, possibly a sign of the evolution of human brain power.
The fieldwork and laboratory work for this project have been funded by grants from the National Science Foundation (NSF) since 1999 (grants BCS 99-12465, BCS 01-30713 and BCS 05-24087).
