Journal ArticleDOI
2.5-million-year-old stone tools from Gona, Ethiopia
Sileshi Semaw,Paul R. Renne,John W.K. Harris,Craig S. Feibel,Raymond L. Bernor,N. Fesseha,K. Mowbray +6 more
TL;DR: The artefacts show surprisingly sophisticated control of stone fracture mechanics, equivalent to much younger Oldowan assemblages of Early Pleistocene age, which indicates an unexpectedly long period of technological stasis in the Oldowan.
Journal ArticleDOI
Early hominin diet included diverse terrestrial and aquatic animals 1.95 Ma in East Turkana, Kenya
David R. Braun,John W.K. Harris,Naomi E. Levin,Jack T. McCoy,Andy I.R. Herries,Marion K. Bamford,Laura C. Bishop,Brian G. Richmond,Brian G. Richmond,M. Kibunjia +9 more
TL;DR: The evidence here shows that these critical brain-growth compounds were part of the diets of hominins before the appearance of Homo ergaster/erectus and could have played an important role in the evolution of larger brains in the early history of the authors' lineage.
Journal ArticleDOI
4,300-Year-old chimpanzee sites and the origins of percussive stone technology
Julio Mercader,Huw Barton,Jason Gillespie,John W.K. Harris,Steven L. Kuhn,Robert T. Tyler,Christophe Boesch +6 more
TL;DR: The “Chimpanzee Stone Age” pre-dates the advent of settled farming villages in this part of the African rainforest and suggests that percussive material culture could have been inherited from an common human–chimpanzees clade, rather than invented by hominins.
Journal ArticleDOI
Early Hominin Foot Morphology Based on 1.5-Million-Year-Old Footprints from Ileret, Kenya
Matthew R. Bennett,John W.K. Harris,Brian G. Richmond,Brian G. Richmond,David R. Braun,Emma Mbua,Purity Kiura,Daniel Olago,M. Kibunjia,Christine Omuombo,Anna K. Behrensmeyer,David Huddart,Silvia Gonzalez +12 more
TL;DR: The Ileret prints show that by 1.5 Ma, hominins had evolved an essentially modern human foot function and style of bipedal locomotion, with a relatively adducted hallux, medial longitudinal arch, and medial weight transfer before push-off.
Journal ArticleDOI
FxJj50: An early Pleistocene site in northern Kenya
Henry T. Bunn,John W.K. Harris,Glynn Isaac,Zefe Kaufulu,Ellen M. Kroll,Kathy Schick,Nicholas Toth,Anna K. Behrensmeyer +7 more
TL;DR: In the Upper Member of the Koobi Fora Formation in Kenya as discussed by the authors, a cluster of stone artefacts and broken up bones which accumulated 1-5 million years ago on the banks of a water course have been found.
