Inspired by the BBC programme “A history of the world in 100 objects”  Martin Budden visited the British Museum. He was particularly interested in seeing two objects from the cradle of humanity, the Olduvai Gorge in northern Tanzania: the Olduvai stone chopping tool (made 1.8 million years ago) and the Olduvai handaxe (made 1.2 – 1.4 million years ago).
