Proceedings of the National Academy of Sciences of the USA 107:8910–8917. Sørensen, Bent. 1998. The Arabian Sea dust core shows a 100,000-year oscillation between wet and dry with the most intense and long-lasting dry periods corresponding to the major glacial advances in the Northern Hemisphere (fig. Although an estimate, the occipital angle falls between ZKD H. erectus and modern humans. 200,000 years ago, … Environmental and genetic data suggest that European hominins were primarily shaped by drift, while both factors operated in Africa. Traditionally, Middle Pleistocene hominin fossils that cannot be allocated to Homo erectus sensu lato or modern H. sapiens have been assigned to different specific taxa. The Middle Pleistocene is a crucial time period for studying human evolution in Europe, because it marks the appearance of both fossil hominins ancestral to the later Neandertals and the Acheulean technology. Journal of Human Evolution 30:243–276. In the early 1990s, it was proposed that H. erectus and H. sapiens overlapped in China (Chen and Zhang, 1991; Chen et al., 1994; Groves and Lahr, 1994).6 The primary evidence for this was the initial dating of the Hexian H. erectus fossils at ∼190–150 ka and the nearby Chaoxian archaic H. sapiens fossils, which were initially dated to ∼200–160 ka (Chen and Zhang, 1991). A case in point may be the distinct canine fossa, which appears in the Gran Dolina H. antecessor fossils and may have later become a prominent feature of archaic H. sapiens in eastern Asia, though it should be noted that the character was identified in Yunxian H. erectus as well (Etler, 2004). The Sima de los Huesos crania (Sierra de Atapuerca, Spain): a comparative study. Interestingly however, Weaver et al. Late Quaternary palaeoenvironments of southern Africa. In Rethinking the human revolution: new behavioural and biological perspectives on the origin and dispersal of modern humans. Explanations of the anatomical differences have largely focused on adaptation (directional selection) to climate and habitual activity, but it is hard to rule out the alternative of genetic drift. The posterior part of the nuchal plane in front of the occipital torus, 13. Likewise, Rohling et al. Late Pleistocene Human Evolution in Eastern Asia: Behavioral Perspectives. Terrestrial apes and phylogenetic trees. Late Pleistocene demography and the appearance of modern human behavior. Jun et al. Drift slows in large populations but accelerates in small populations and can override the signal of all but the strongest selective pressures. 2001; Graves et al. 2010) and recovery and analysis of nuclear and mitochondrial DNA from “Denisovans,” a third lineage that separated from modern humans slightly before Neanderthals (Meyer et al. 's (2006) study conform to what might be expected of a female hominin living in this type of environment. Growth processes in teeth distinguish modern humans from Homo erectus and earlier hominins. For example, Roseman (2004) found a strong correlation between cold climate and a cranial vault shape that was brachycephalic, as well as certain aspects of the nasal morphology. 2012; Kappelman 1996). 500,000 to 400,000 years ago (Middle Pleistocene), archaic humans split off from other groups of that period living in Africa and East Asia, ultimately settling in … 3rd edition. 1988. Middle Pleistocene taxonH. erectus evolved into H. heidelbergensis in Africa •H. Bulging lateral to the upper part of pyriform aperture, 15. (1986) assigned Ryonggok to archaic H. sapiens, primarily based on the initial chronometric dating analysis. Nevertheless, it might be argued that giving latinized specific names to different fossils subconsciously implies reproductive isolation. (1984); data for various hominin taxa from Bailey and Liu (2010); all data are population averages]. Quaternary Science Reviews 26:287–299. 1). Thus, in Groves and Lahr's (1994) view, there is no evidence of regional continuity. Although determining age of individual clearly past the juvenile stage to exact year should be treated cautiously, the human mandibles clearly represent fully mature or aged individuals. Dean, M. Christopher, and B. Holly Smith. 2009. Ruff, Christopher B., Erik Trinkaus, and Trenton W. Holliday. However, in reviewing the case for allocating the eastern Asian Middle Pleistocene archaic H. sapiens into H. heidelbergensis, there do not seem to be many strong arguments. In any group other than Hominidae the presence of several clearly recognizable morphs in the record of the middle to upper Pleistocene would suggest (indeed, demonstrate) the involvement of several species.” (Tattersall, 1986, p 170). 2006.

Middle Pleistocene Hominin Teeth from Longtan Cave, Hexian, China. Partial genetic turnover in Neandertals: continuity in the East and population replacement in the West. The stature of early modern humans from the Levalloiso-Mousterian of the Levant and the Gravettian of Europe is particularly striking relative to Neanderthals and almost all other samples from Europe before the twentieth century (Carretero et al. For instance, the Arago 13 hemimandible displays elements of a mental eminence (Rightmire, 2008; see detailed review of the hominin fossil evidence for the “chin” by Schwartz and Tattersall, 2000).
