Book Description
Olduvai Groge is a valley in the Serengeti Plains at the western margin of the Eastern Rift Valley in northern Tanzania. The formations discussed in this volume, Beds I and II, were deposited in the Lower and Middle Pleistocene and have yielded large quantities of the remains of early man, in the form of bones and stone tools and evidence of the environment in which they lived. Bed I, in which remains of Australopithecus boisei and Homo habilis have been found, is firmly dated between 1.9 million years for the lowest level and 1.65 million years for a level below the top. This third volume describes the excavations. In Part I, starting with the lowest levels and devoting a chapter to each main level, Dr Leakey describes the actual process of excavation and the finding of the principal remains. In Part II, Dr Leakey describes the circumstances of the discovery of the hominid skeletal remains. These range from purposive excavation to accidental discovery while collecting small stones for mixing in concrete. Finally, mammalian bones, as tools and as food remains are discussed.

Book Description
Nearly thirty million species of organisms are believed to now live on Earth. In addition to accumulating evidence from classical biology, paleontology and earth science, the recent progress of molecular biology has provided new insights into understanding how present-day organisms have evolved with such tremendous diversity. Molecular biological studies show us that all living forms, including E. coli and human beings, derive from a single ancestor that emerged some 4 billion years ago on Earth. This volume aims to discuss the motifs of organismic evolution from the viewpoints of biogeo-interactions and diversification of the genetic systems. Based on these fundamental understandings, the last section of this volume is devoted to human evolution that includes phylogeny of man as well as evolution of human culture. Such comprehensive discussion will give us a synthesized view of the evolution of life, that is undoubtedly one of the most important problems not only for science but also for human culture in general.
