On 15 August 1959 Dr L. S. B. Leakey announced the discovery, in the lowest level of Olduvai Gorge, of a new and beautifully preserved fossil cranium of a hominid, which he tentatively named Zinjanthropus boisei. For this second volume, Professor Tobias has undertaken a definitive analysis of the cranium.
