The control of fire by "Homo erectus" is generally accepted by archaeologists to have begun some 400,000 years ago, with claims regarding earlier evidence finding increasing scientific support. Burned wood has been found in layers that carried the Java Man fossils in Trinil, dating to around from 500,000 to 830,000 BP. However, because Central Java is a volcanic region, the charring may have resulted from natural fires, and there is no conclusive proof that "Homo erectus" in Java controlled fire. It has been proposed that Java Man was aware of the use of fire, and that the frequent presence of natural fires may have allowed Java Man "opportunistic use [... that] did not create an archeologically visible pattern".
