Early Homo at 2.8 Ma from Ledi-Geraru, Afar, Ethiopia
TLDR
A partial hominin mandible with teeth from the Ledi-Geraru research area, Afar Regional State, Ethiopia, is found that establishes the presence of Homo at 2.80 to 2.75 Ma, confirming that dentognathic departures from the australopith pattern occurred early in the Homo lineage.
Early Hominin Foot Morphology Based on 1.5-Million-Year-Old Footprints from Ileret, Kenya
TLDR
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.
Early hominin diet included diverse terrestrial and aquatic animals 1.95 Ma in East Turkana, Kenya
TLDR
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.
Raw material quality and Oldowan hominin toolstone preferences: evidence from Kanjera South, Kenya
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.
Earliest Archaeological Evidence of Persistent Hominin Carnivory
TLDR
Three large well-preserved zooarchaeological assemblages from Kanjera South, Kenya are detailed, providing the earliest archaeological evidence of sustained hominin involvement with fleshed animal remains (i.e., persistent carnivory), a foraging adaptation central to many models of hom inin evolution.
Oldowan behavior and raw material transport: perspectives from the Kanjera Formation
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
Old stones' song: use-wear experiments and analysis of the Oldowan quartz and quartzite assemblage from Kanjera South (Kenya).
TLDR
Use-wear related to USO processing extends the archaeological evidence for hominin acquisition and consumption of this resource by over 1.5 Ma, highlighting the adaptive significance of lithic technology forhominins at Kanjera.
Response to Comment on “Early Homo at 2.8 Ma from Ledi-Geraru, Afar, Ethiopia”
TLDR
The reexamination of the evidence confirms that LD 350-1 falls outside of the pattern that A. sediba shares with Australopithecus and thus is reasonably assigned to the genus Homo.
Landscape-scale variation in hominin tool use: Evidence from the Developed Oldowan.
TLDR
Digital-image-analysis techniques are used to investigate the intensity of reduction in single-platform cores of the Developed Oldowan of the Okote Member, Koobi Fora Formation to suggest that this method provides a more accurate measure of reduction intensity than previous applications of a unifacial-scraper model.
Oldest Evidence of Toolmaking Hominins in a Grassland-Dominated Ecosystem
TLDR
These data demonstrate that grassland-dominated ecosystems did in fact exist during the Plio-Pleistocene, and that early Homo was active in open settings, and indicates that by 2.0 Ma hominins, almost certainly of the genus Homo, used a broad spectrum of habitats in East Africa, from open grassland to riparian forest.
