2011. New York: Basic. Roseman, Charles C. 2004. These damaged but relatively complete adult specimens show a mixture of features associated both with Homo erectus and with 'archaic H. sapiens'. Behar, Doran M., Richard Villems, Himla Soodyall, Jason Blue-Smith, Luísa Pereira, Ene Metspalu, Rosaria Scozzari, et al. Stringer, Chris. Journal of Human Evolution 59:445–464. 2010) and may have been the primitive condition for Middle Pleistocene Homo (Arsuaga et al. The evolutionary transition from H. ergaster/erectus to modern humans occurred during the Middle Pleistocene. 2010). However, even small amounts of gene flow from dispersing H. heidelbergensis groups into eastern Asia during the Middle Pleistocene is probably the most parsimonious explanation as to why similar morphological features occasionally appear among penecontemporaneous western and eastern Old World hominins. White, Tim D., Berhane Asfaw, David DeGusta, Henry Gilbert, Gary D. Richards, Gen Suwa, and F. Clark Howell. (2008), comparative metric analysis more closely aligns the Salkhit hominin with Neandertals, H. erectus sensu stricto, and archaic H. sapiens and away from modern humans of East Asian affinity. ARCHAEOLOGICAL RECORDS | Human Evolution in the Quaternary. 107 HUMAN ROOTS: AFRICA AND ASIA INTHK M'DDt.K PI .RISTOCENIi NORTHWESTERN AFRICAN MIDDLE PLEISTOCENE HOMINIDS However, some metrical features, such as the length of the parietal arc, the height of the temporal squama or the relative height of the braincase, are at the upper limit of the Homo erectus sensu lato and are reminiscent of later Middle Pleistocene … Brown, Francis H., Ian McDougall, and John G. Fleagle. The nature of hominin biological evolution during the Middle Pleistocene is one of the most debated topics in paleoanthropology today. 1997). 2008. 1993. A female Homo erectus pelvis from Gona, Ethiopia. A partial maxilla of a juvenile was also excavated from Xujiayao. 2006. 2007. 3). Tenfold population increase in western Europe at the Neandertal-to-modern human transition. Ma U'Oi is situated in a tower karst region of the Annamitic Mountain Chain, with many additional caves located in the region (Demeter et al., 2005). Metric analysis of the mesiodistal and buccal‐lingual measurements of the Ryonggok upper molars also generally fall within the range of modern humans (Fig. Based on these arguments, Rightmire (2004, p 119) concludes that “the Asian hominins can be viewed as more closely related to other (western) Middle Pleistocene populations than to local, late‐surviving Homo erectus” and that “[t]he spread of some populations of Homo heidelbergensis into the Far East cannot be ruled out” (Rightmire, 1998, p 225). Scientific drilling in the Great Rift Valley: the 2005 Lake Malawi Scientific Drilling Project: an overview of the past 145,000 years of climate variability in Southern Hemisphere East Africa. I evaluate the arguments that 1) the late Middle Pleistocene hominin fossils from eastern Asia should be included within the H. heidelbergensis hypodigm, 2) whether a different taxonomic name might be more apropos, or 3) whether the archaic H. sapiens classification should continue to be used. The biogeographic range reconstructions suggest the presence of a geographically widespread, mid-Pleistocene ancestor to humans, Neanderthals, H. heidelbergensis and H. rhodesiensis. Because of this biogeographic distinction, I divide this review of the hominin fossil record into Northeast and SE Asia (Fig. Given congruent estimates for stature based on femurs and tibiae, the Sima de los Huesos sample appears to have less shortened distal limb segments than Neanderthals (Carretero et al. Science 328:710–722. It should be noted that Etler (1996) observed the presence of a canine fossa on the Yunxian H. erectus fossils, which may be penecontemporaneous with Gran Dolina or even older. American Journal of Physical Anthropology. Statistical evaluation of alternative models of human evolution. I restrict the following description to the Maba partial cranium, with more detailed description of the partial mandible and teeth presented later (Bae et al., n.d.). For example, in his review of the evidence for modern human origins in China, Pope (1992, p 251) chose to “emphasize a few anatomical regions which seem to best display variations between the Premoderns and Chinese Homo erectus: i.e., the face (in frontal and lateral aspects), the glenoid region (in basal aspect), and the occipital region (in posterior and lateral aspect).” In particular, the midfacial region is considered to be useful for studying inter‐regional population and evolutionary morphological variation related to behavioral changes, though some of the traits may be correlated with the biomechanics related to mastication (Brace, 1967; Gill et al., 1988; Brace and Hunt, 1990). More recent chronometric dating analyses of many of the archaic H. sapiens localities in China indicate that the picture is much more complicated. 2011. 1. Tattersall rails against lumping all Middle Pleistocene taxa not readily allocated to H. erectus into H. sapiens, when he writes “[t]he ‘grade’… is one of the most destructive canards that paleoanthropology has ever seen fit to inflict upon itself: a meaningless and undefined concept, apparently leaning heavily on brain size, that can be used to entomb all kinds of morphological loose ends and thus eliminate the need to examine them” (Tattersall, 1986, p 173). 6 | Sequential 13C and 18O measurements for equid samples SGS180, SGS57 and SGS1094 and P. recki samples TAG14 301 and TAG14 129 from the middle Pleistocene levels of Tis al Ghadah. Rather, the degree of admixture between dispersing modern humans with indigenous hominins in places like Europe and eastern Asia is receiving greater attention in paleoanthropology. 2011. 2001. However, the Hexian teeth differ from H. ergaster in features such as conspicuous vertical grooves on the labial/buccal surfaces of the central incisor and the upper … heidelbergensis sensu stricto refers to a European chronospecies of H. neanderthalensis while H. heidelbergensis sensu lato is considered to be an Afro-European species ancestral to modern humans and Neandertals.. Proceedings of the National Academy of Sciences of the USA 104:20753–20758. Both African and European Middle Pleistocene hominins tended to be medium to tall in stature (Carretero et al. Yokpo Daehyundong hominin fossils. However, Jinniushan has also been determined to be a female, based on the morphology of the pubis which displays a subpubic concavity and the “medial aspect of the ischiopubic ramus [which] is ridged rather than flat” (Rosenberg et al., 2006, p 3552). Irrespective of whether natural selection or genetic drift is more influential, results of these studies suggest that genetic correlates need to somehow be factored into any cladistic analysis of human morphological variation. These results are exciting and motivate one to take a closer look at some of the recent genetic advances. Many thanks to Erella Hovers and Steve Kuhn for the invitation to participate in this stimulating conference and to the Wenner-Gren Foundation for organizing and funding it. In Orofacial growth and development. The human career. These patterns help to illuminate a particularly irksome issue in research on the origin of modern humans: the question of why modern humans only expanded out of Africa at 50–60 ka if “anatomically modern” morphology arose between 200 and 150 ka (e.g., Klein 2009). 2nd edition. In Europe, the Neanderthal lineage evolved a series of apomorphies, including midfacial prognathism, a posterior position of the mental foramen, a retromolar gap in the mandible, a broad suprainiac fossa that is oval in form, a large juxtamastoid process coupled with a small mastoid process, an occipital bun, double-arched browridges that are reduced in absolute volume and vertical thickness compared with those of Middle Pleistocene hominins, and a substantially larger brain than those of most Middle Pleistocene hominins (Hublin 2009; Stringer 2007). Indeed, the recent analysis of Neandertal DNA, which indicates some degree of admixture with modern H. sapiens is a case in point (Green et al., 2010). Proceedings of the National Academy of Sciences of the USA 108:20422–20427. 1990, the number of distinct hominin taxa has almost doubled), it would seem that he maintains the same negative opinion of the designation “archaic H. sapiens.” Indeed, Tattersall and Schwartz (2008, p 54) concluded recently that “it is evident that virtually all of those hominid fossils whose exact historical significance has been obscured by their assignment to the all‐embracing wastebasket of ‘archaic Homo sapiens,’ in fact belonged to an array of separate biological entities, none of them evidently closely affiliated to living Homo sapiens.” In Tattersall's view, these different Middle Pleistocene taxa should be classified as distinct species. The direct influence of climatic conditions on population sizes in Europe and Africa allows a series of predictions about the relative ability of selection and drift to produce changes in hominin populations. The evolution and development of cranial form in Homo sapiens. Other authors have calculated additional estimates for the divergence times between Neanderthals, Denisovans, and modern humans (e.g., Harris and Nielsen 2013; Li, Mulliken, and Reich 2010; Meyer et al. This result implies that similar dynamics, likely attributable to climatic cycles, affected archaic and modern populations in Eurasia in very similar ways. Holliday, Trenton W. 1997. As new morphologies may be effectively invisible in the fossil record during periods of contracted population size, they may, in fact, appear in the record only slightly later, once population sizes had rebounded. 2007. 2012; Reich et al. New York: Knopf. A number of measurements and indices derived from the Dali cranium also fall within the range of archaic H. sapiens and are intermediate between H. erectus and modern H. sapiens. The results obtained enable us to depict an astonishing movie printed in rock, describing some body features and common moments of the everyday movements of a hominin who lived about 350 ka. Cladistics organizes “things (be they species, populations, or artifacts) into a hierarchical pattern that reflects closeness of relationship based on the attributes (e.g., genes or morphology) exhibited by the individuals within those groups” (Lycett, 2007, p. 543–544). Archaic, early, or premodern H. sapiens are the terms used most frequently to refer to the eastern Asian hominins that cannot be allocated to either H. erectus or modern H. sapiens. Indeed, Groves and Lahr (1994, p. 3) concluded that “Homo erectus at first existed by itself in China; Homo heidelbergensis then entered and the two coexisted for a time; finally H. erectus became extinct there, and H. heidelbergensis persisted alone: an early ‘replacement’ event.”. For example, Rightmire (2004) notes a number of cases of effective hominin hunting in Middle Pleistocene western Eurasia (e.g., Boxgrove, Schoningen). Such early Middle Pleistocene hominins were not anatomically modern. Ebb and flow or regional extinctions? The formal application of generic and specific names simulates a precision that often does not exist.” Indeed, the title of the recent Yin et al. Its mandibular body is tall and thick anteriorly. The results showed that the most probable scenario (isolation and drift in the western and eastern populations of Neanderthals at 48 ka) would have involved an effective population size (Ne) of western Neanderthals of only 300 females, a marked reduction from the estimate for the eastern subpopulation ( females). “The obviously great diversity in using the name Homo heidelbergensis reveals that it is hardly a well‐defined taxon” (Brauer, 2008, p 32), thus leading Brauer (2008, p 35) to conclude that “the use of archaic Homo sapiens still appears adequate and plausible.”. 2007. Journal of Anthropological Archaeology 30:17–29. Trinkaus’s (1983) influential analysis of the Shanidar Neanderthals emphasized that Neanderthal morphologies met adaptive needs for greater strength or leverage relative to modern humans. Although other metric data is available for the North Korean hominin fossils, how the measurements match western terminology is still being ascertained. Hong Ao, Chun-Ru Liu, Andrew P. Roberts, Peng Zhang, Xinwen Xu, An updated age for the Xujiayao hominin from the Nihewan Basin, North China: Implications for Middle Pleistocene human evolution in East Asia, Journal of Human Evolution, 10.1016/j.jhevol.2017.01.014, 106, (54-65), (2017). Any test of these hypotheses faces practical limitations, including an incomplete fossil record, poor dating of some fossils, and inadequate resolution of current methods in pinpointing morphological or genetic changes to exact spots in the 100,000-year glacial and faster insolation cycles. Williams, Martin, Michael Talbot, Paul Aharon, Yassin Abdi Salaam, Frances Williams, and Knut Inge Brendeland. The occipital fragment (upper left squamous region) is morphologically indistinguishable from archaic and modern H. sapiens (Demeter et al., 2005). 2010. Within this count, ten axes were discovered, eighteen scraping tools were uprooted, one steel chisel tool (for … Detecting interregionally diversifying natural selection on modern human cranial form by using matched molecular and morphometric data. Distance from Africa, not climate, explains within-population phenotypic diversity in humans. 2002. 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 arrows show possible directions of colonization from regions of higher population density into adjacent areas. De Villiers, H., and L. P. Fatti. Perhaps the most pernicious, and certainly the most pervasive of all the various devices invented to sustain this new orthodoxy, was ‘archaic Homo sapiens.’” (Tattersall and Schwartz, 2008, p 50). Simpson, Scott W., Jay Quade, Naomi E. Levin, Robert Butler, Guillaume Dupont-Niven, Melanie Everett, and Sileshi Semaw. -Dates to 1.6 mya. Inferred population size changes in the history of Denisovans. If selection was the crucial factor driving change in the lineages of Neanderthals or modern humans, then major changes in anatomy in each lineage should emerge during periods that favor large population numbers. The North Korean fossils date to the Middle to Late Pleistocene based usually on biostratigraphy, but occasionally a U‐series or TL date has been reported (Norton, 2000).
