To put the age of these tools into perspective, our species Homo sapiens did not appear until roughly 300,000 years ago. Other hominins existing at the time included the genus Australopithecus, known for the famous even-older fossil "Lucy." The Nyayanga site today is a gully on Homa Mountain's western flank along Lake Victoria in southwestern Kenya. When the tools were made, it was woodland and grassland along a stream, teeming with animals.
