Early Homo at 2.8 Ma from Ledi-Geraru, Afar, Ethiopia
- B. Villmoare, W. H. Kimbel, +6 authors K. Reed
- Biology, Medicine
- Science
- 20 March 2015
Finding Homo nearly 3 million years ago The fossil record of humans is notoriously patchy and incomplete. Even so, skeletal remains and artifacts unearthed in Africa in recent decades have done much… Expand
Early Hominin Foot Morphology Based on 1.5-Million-Year-Old Footprints from Ileret, Kenya
- M. Bennett, J. W. Harris, +9 authors S. González
- Geography, Medicine
- Science
- 27 February 2009
Hominin footprints offer evidence about gait and foot shape, but their scarcity, combined with an inadequate hominin fossil record, hampers research on the evolution of the human gait. Here, we… Expand
Early hominin diet included diverse terrestrial and aquatic animals 1.95 Ma in East Turkana, Kenya
- D. Braun, J. K. Harris, +6 authors M. Kibunjia
- Biology, Medicine
- Proceedings of the National Academy of Sciences
- 31 May 2010
The manufacture of stone tools and their use to access animal tissues by Pliocene hominins marks the origin of a key adaptation in human evolutionary history. Here we report an in situ archaeological… Expand
Raw material quality and Oldowan hominin toolstone preferences: evidence from Kanjera South, Kenya
- D. Braun, T. Plummer, J. Ferraro, P. Ditchfield, L. Bishop
- Geology
- 1 July 2009
The role of raw material quality in Oldowan technology has not been fully explored. There are numerous studies suggesting Oldowan hominins preferred certain types of stone for artifact manufacture.… Expand
Earliest Archaeological Evidence of Persistent Hominin Carnivory
- J. Ferraro, T. Plummer, +8 authors R. Potts
- Biology, Medicine
- PloS one
- 25 April 2013
The emergence of lithic technology by ∼2.6 million years ago (Ma) is often interpreted as a correlate of increasingly recurrent hominin acquisition and consumption of animal remains. Associated… Expand
Oldowan behavior and raw material transport: perspectives from the Kanjera Formation
- D. Braun, T. Plummer, +4 authors R. Potts
- Geology
- 1 August 2008
The archaeological record of Oldowan hominins represents a diverse behavioral system. It has been suggested that exploitation of lithic resources by Oldowan hominins was simplistic and represented… Expand
Visible light emission from semiconducting polymer diodes
We report visible light emission from Shottky diodes made from semiconducting polymers, confirming the discovery by the Cambridge group [Nature 347, 539 (1990)]. Our results demonstrate that… Expand
Response to Comment on “Early Homo at 2.8 Ma from Ledi-Geraru, Afar, Ethiopia”
- B. Villmoare, W. H. Kimbel, +6 authors K. Reed
- Geography, Medicine
- Science
- 19 June 2015
Hawks et al. argue that our analysis of Australopithecus sediba mandibles is flawed and that specimen LD 350-1 cannot be distinguished from this, or any other, Australopithecus species. Our… Expand
Landscape-scale variation in hominin tool use: Evidence from the Developed Oldowan.
- D. Braun, M. Rogers, J. K. Harris, S. J. Walker
- Geology, Medicine
- Journal of human evolution
- 1 December 2008
The relationship between artifact manufacture, use, and discard in the Developed Oldowan is complex. Here we use digital-image-analysis techniques to investigate the intensity of reduction in… Expand
Oldest Evidence of Toolmaking Hominins in a Grassland-Dominated Ecosystem
- T. Plummer, P. Ditchfield, +5 authors R. Potts
- Geography, Medicine
- PloS one
- 21 October 2009
Background Major biological and cultural innovations in late Pliocene hominin evolution are frequently linked to the spread or fluctuating presence of C4 grass in African ecosystems. Whereas the deep… Expand
