Sir Grahame Clark (died 1995) was the foremost figure in world prehistoric studies: indeed, he invented the idea of a world prehistory. He established pioneering research projects, sending out his students to all corners of the world. This volume presents new developments and perspectives in Clark's major fields of interest, as well as reflecting on his own contribution to archaeological scholarship. Many of the eminent authors are former students or colleagues, from as far afield as Australia, New Zealand, South Africa, and the United States. The topics covered range from the origins of our own genus in Africa around two million years ago, to the issues of the Later Stone Age and the emergence of civilization in Northern Europe, Anatolia, and South-east Asia.
