The oldest Oldowan tool sites, from around 2.6 million years ago, have previously been confined to Ethiopia’s Afar Triangle. We describe sites at Nyayanga, Kenya, dated 3.032 2.581 ago and expand this distribution by over 1300 kilometers. Furthermore, we found two hippopotamid butchery associated with mosaic vegetation a C 4 grazer–dominated fauna. Tool flaking proficiency was comparable that of younger assemblages, but pounding activities were more common. use-wear bone damage indicate...
The 2002 discovery of a robust modern human mandible in the Peştera cu Oase, southwestern Romania, provides evidence early humans lower Danubian Corridor. Directly accelerator mass spectrometry radiocarbon (14C)-dated to 34,000-36,000 14C years B.P., Oase 1 is oldest definite specimen Europe and perspectives on emergence evolution northwestern Old World. moderately long exhibits prominent tuber symphyseos overall proportions that place it close earlier Upper Paleolithic European specimens....
The Protoaurignacian culture is pivotal to the debate about timing of arrival modern humans in western Europe and demise Neandertals. However, which group responsible for this remains uncertain. We investigated dental associated with Protoaurignacian. lower deciduous incisor from Riparo Bombrini human, based on its morphology. upper Grotta di Fumane contains ancient mitochondrial DNA a human type. These teeth are oldest an Aurignacian-related archaeological context, confirming that by 41,000...
The Rising Star cave system has produced abundant fossil hominin remains within the Dinaledi Chamber, representing a minimum of 15 individuals attributed to Homo naledi. Further exploration led discovery material, now comprising 131 specimens, second chamber, Lesedi Chamber. Chamber is far separated from system, and represents depositional context for remains. In each three collection areas diagnostic skeletal material allows clear attribution H. Both adult immature present. represent at...
Elemental records in teeth reveal prehistoric seasons of Neanderthal birth, weaning, childhood illness, and neurotoxic exposures.
Abstract This study uses elliptical Fourier analysis to quantify shape differences observed in the P 4 crown of Neandertals and anatomically modern humans. Previously, was assessed qualitatively, results suggested marked between humans (Bailey [2002] New Anat. 269 :148–156). The goal this investigate more detail, quantifying it order determine its utility for taxonomic classification phylogenetic analysis. A comparison mean shapes confirms that mesiolingual portion is truncated Neandertals,...
Abstract The nearly ubiquitous presence of a continuous crest connecting the protoconid and metaconid lower molars (often referred to as middle trigonid crest), is one several dental traits that distinguish Homo neanderthalensis from sapiens . This study examined variation in patterns on enamel dentine surfaces (1) evaluate concordance between morphology crests at inner outer surfaces; (2) examine their developmental origin(s); (3) trait polarity through comparison with Australopithecus...
The Uluzzian techno-complex is commonly considered to be a "transitional industry" mostly on the basis of some inferred characteristics such as chiefly flake-based production, small amount Upper Palaeolithic-like tools and combination Middle Palaeolithic elements both in toolkit technical systems. Following its discovery, was identified Italian counterpart French Châtelperronian attributed Neandertals. However, study issued 2011 has established modern character two deciduous teeth found 1964...
The recently described Denisovan hemimandible from Xiahe, China [F. Chen et al., (2019) Nature 569, 409-412], possesses an unusual dental feature: a 3-rooted lower second molar. A survey of the clinical and bioarchaeological literature demonstrates that molar is rare (less than 3.5% occurrence) in non-Asian Homo sapiens In contrast, its presence Asian-derived populations can exceed 40% New World. It has long been thought prevalence molars Asia relatively late acquisition occurring well after...
Abstract Previous research into tooth crown dimensions and cusp proportions has proved to be a useful way identify taxonomic differences in Pliocene Pleistocene fossil hominins. The present study identified changes both M 1 size within the genus Homo , with overall reduction apparently occurring two main stages. first stage (a of ca. 17%) is associated emergence ergaster erectus sensu stricto . second 10%) occurs sapiens but reduced modern human was only attained Upper Paleolithic times....
The life history pattern of recent humans is uniquely derived in many its aspects including an extended post-reproductive lifespan combined with short interbirth intervals. A number theories have been proposed to explain the evolution this unusual pattern. However most difficult test due fragmentary nature hominin fossil record and lack methods capable inferring such later events. In search a method we tested hypothesis that physiologically impactful events parturition menopause are recorded...
