約40万年前は狩猟の形態での生活でしたか？
Stone spearheads dated as early as 500,000 years ago were found in South Africa. Wood does not preserve well, however, and Craig Stanford, a primatologist and professor of anthropology at the University of Southern California, has suggested that the discovery of spear use by chimpanzees probably means that early humans used wooden spears as well, perhaps, five million years ago.
The earliest dated find of surviving wooden hunting spears dates to the very end of the Lower Paleolithic, just before 300,000 years ago.The Schöningen spears, found in 1976 in Germany, are associated with "Homo heidelbergensis".
