This volume is devoted to exploring the present state of knowledge about the middle Pleistocene and the processes of human physical and cultural development the interval represents. This volume is based on a symposium held at Burg Wartenstein in Austria in July 1973. The symposium brought together leading earth scientists, paleobiologists, and paleoanthropologists in an attempt to synthesize all available information on Middle Pleistocene humans.
