In Arusha, there is a very nice little National Natural History Museum that houses many of the Leaky's famous discoveries in Olduvai Gorge. Our archaelology professor, Dr. David Pokotylo demonstrates how our ancestors used a hammerstone and raw materials (such as quarzite, chert, obsidian, flint, etc) to make stone tools by hitting the raw material in such a way it would flake into a very sharp edged tool.
We were also in luck as Dr. Robert Blumen- schine let us look at some very nice specimens that he and his team had discovered. One was a tooth from an early hominid, and the really cool thing was an entire hominid jaw dated to about 1.8 MYA. The jaw was in pieces, but had been reconstructed, and only one tiny pieces was missing from the plate.
