Description Summary

Acheulean Site known for refined volcanic lava material

Early Pleistocene

Compared to previous periods, the climate of eastern Africa was generally colder, but more importantly, it was variable. There were significant swings between warm and wet and cold and dry. Similarly, the landscape frequently changed from forested to grassy. Animal life was in great flux with successions of organisms suited to survive in those environments. Hominids and their hominin descendants grew increasingly dependent on tools to survive the changing environments.
