description: International symposium at the University of Tübingen, Germany, 8th-12th April 2001. This symposium explores the relationship between environmental change and the key events in the evolution and dispersal of the human clade, from its origin around 5-8 Myr to the expansion of Homo sapiens across the globe between 100 Kyr and 15 Kyr.
abstract: The Middle Pleistocene Africa in is traditionally viewed as a period of uniformity and stasis. Its stone technology is most commonly referred to the Acheulian, and the maker of this technology is thought to be Homo erectus. Closer examination reveals a more complex picture. Fossil discoveries in both East and South Africa demonstrate that the origin of Homo sapiens is a Middle Pleistocene phenomenon. The taxonomic status of more archaic African hominids from this timespan is ambiguous, and the presence of more than one hominid species is likely. In East Africa, where volcanics make temporal control possible through the application of the K/Ar and 40Ar/39Ar methods, the Middle Pleistocene archaeological record displays a remarkable degree of variability. Assemblages that can be ascribed both to the Oldowan and to the Middle Stone Age are present at Middle Pleistocene localities in the Middle Awash, Ethiopia, and in the Kapthurin Formation, Kenya. East African artifact occurrences that can be attributed to the Acheulian exhibit a variety of approaches to biface manufacture and flake production, as well as highly variable proportions and types of formal tools. Behaviors usually thought characteristic of later time periods, such as blade production, projectile points, and the use of pigment, are present in the archaeological record of the Kapthurin Formation, Kenya, before 280 ka, and long distance trade or transport of obsidian is demonstrated before 130 ka at a number of sites in Kenya and Tanzania.
