Grassy beginning for earliest Homo

(Arizona State University) Following the discovery of the Ledi-Geraru jaw, an environmental study of the eastern African Plio-Pleistocene was conducted to investigate the long-standing hypotheses that the transition from Australopithecus to Homo was linked to the spread of more open and arid environments. Data indicate that the Ledi-Geraru Research Project area in the Lower Awash Valley and Omo-Turkana Basin were largely similar, but important environmental differences existed at the time of earliest Homo (~ 2.8 Ma).
