Environment and behavior of 2.5-million-year-old Bouri hominids.
The combined evidence suggests that behavioral changes associated with lithic technology and enhanced carnivory may have been coincident with the emergence of the Homo clade from Australopithecus afarensis in eastern Africa. Expand
Stratigraphic, chronological and behavioural contexts of Pleistocene Homo sapiens from Middle Awash, Ethiopia
Stratigraphically associated Late Middle Pleistocene artefacts and fossils from fluvial and lake margin sandstones of the Upper Herto Member of the Bouri Formation, Middle Awash, Afar Rift, Ethiopia and archaeological assemblages contain elements of both Acheulean and Middle Stone Age technocomplexes.

The Middle Stone Age of East Africa and the beginnings of regional identity
- J. D. Clark
- 1 September 1988
The history of research into the Middle Stone Age of East Africa and the present state of knowledge of this time period is examined for the region as a whole, with special reference to… Expand
African Homo erectus: old radiometric ages and young Oldowan assemblages in the Middle Awash Valley, Ethiopia.
Fossils and artifacts recovered from the middle Awash Valley of Ethiopia's Afar depression sample the Middle Pleistocene transition from Homo erectus to Homo sapiens, supporting the hypothesis that Middle Pleistsocene Oldowan assemblages represent a behavioral facies of the Acheulean industrial complex.

New discoveries of Australopithecus at Maka in Ethiopia
The discovery of new fossils from Maka, dated to 3.4 Myr ago, provide powerful support for the interpretation of A. afarensis as a single, ecologically diverse, sexually dimorphic, bipedal Pliocene primate species whose known range encompassed Ethiopia and Tanzania. Expand
The Potassium-Argon Dating of Late Cenozoic Rocks in East Africa and Italy [and Comments and Reply]
A technique for the potassium-argon dating of high potassium feldspars of less than 50,000 years age is described. The technique is applied to the obtaining of high precision ages in the time-range… Expand
Archaeological perspectives in the Nihewan Basin, China
Abstract Paleolithic archaeological sites in the Nihewan Basin (previously Nihowan) in northern China were visited and their excavated materials examined in order to assess their potential for future… Expand
Fire and its roles in early hominid lifeways
Discovery of the uses and later the invention of fire-making are fundamental to humanity. Following reports over the last decade of traces of fire found on Lower Pleistocene archaeological sites in… Expand
Hominid occupation of the East-Central Highlands of Ethiopia in the Plio–Pleistocene
Stone artefacts and fossil evidence suggest that hominids did not reach the high plateau of Ethiopia until ∼1.5 Myr ago. Contact between hominids of the plateau and the Rift Valley seems likely.
