The hominids that made the Acheulean tools and diverse species of animals were attracted by the aquatic life, floodplains, wetlands and lakes. Either the populations were doomed to perish or they changed from Acheulean technology or advanced to a new form of technology. The later deposits of the Olorgesailie indicate the middle of Middle Stone Age (African technology), characterised by lighter stone tools, advanced hunting and emergence of Homo sapiens. The glass compartments display the Acheulean hand-axes, skeletons of extinct animals, bones and skulls of Homo erectus, including the skull of a Turkana boy . As I walk down to the bowl I see excavation and surface scatters that contained hundreds upon hundreds of stone hand-axes.
