TL;DR: Ardipithecus ramidus indicates that despite the genetic similarities of living humans and chimpanzees, the ancestor the authors last shared probably differed substantially from any extant African ape.

TL;DR: 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.

TL;DR: 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.

TL;DR: A newly established chronometric calibration is provided for the Acheulean assemblages of the Konso Formation, southern Ethiopia, which span the time period ∼1.75 to <1.0 Ma, paralleling the emergence of Homo erectus-like hominid morphology.

TL;DR: Konso-Gardula is a palaeo-anthropological area discovered by the 1991 Palaeoanthropological inventory of Ethiopia in the southern Main Ethiopian Rift as discussed by the authors.
