Middle Pleistocene human facial morphology in an evolutionary and developmental context MPS-Authors Freidline, Sarah E. ... Middle Pleistocene human facial morphology in an evolutionary and developmental context. Distally, there is moderate hypertrophy of the medial malleolus and presence of squatting facets in some adult specimens (25%), related by some researchers to a hyperdorsiflexion of the ankle joint (48). The patterning of facial morphology of their predecessors, the Middle Pleistocene humans, is more mosaic showing a mix of archaic and modern morphologies. This great width of the pelvis may also have had obstetric implications, including a nonrotational delivery (56, 57). In addition, we focus in particular on whether the detailed morphological traits found throughout the postcranial skeleton follow a mosaic pattern of evolution, as seen in the crania, and whether there have been changes in the Homo bauplan. We thank our companions in the Atapuerca research and excavation team; M. C. Ortega for her extraordinary and patient restoration of the fossils; A.

Most of the SH humeri display a consistent morphological pattern that distinguishes them from MH and is similar to Neandertals. A subsequent slight increase in body mass occurred only approximately 1 million years later in middle Pleistocene populations (including SH), and these body parameters were largely maintained in the Neandertals. A.G.-O. In contrast, MH show three curvature types (31). Midshaft section (Middle, CT-scan image) is rounded and shows an absence of a pilaster. The robusticity of the fibula overlaps the upper range for MH. The site, The temporal bones from Sima de los Huesos Middle Pleistocene site (Sierra de Atapuerca, Spain). Although middle Pleistocene populations have been described as exceptionally robust (13), phylogenetic hypotheses are based mainly on the more abundant cranial sample (14, 15). Although there are no known pelvic remains attributed to H. habilis, in our view, a ML relatively wide biotype was likely present (as the most parsimonious interpretation) in the earliest members of the genus Homo and was inherited from their early hominin ancestors. Subadult (H-IV, Left) and adult (H-VI, Right) specimens showing the thin medial pillar and broad and deep olecranon fossa. These relate to the ancestry of Homo sapiens in the Middle Pleistocene. Newly found ∼300,000-y-old human remains from Hualongdong (HLD), China, … This pattern is also present in the Neandertals and distinguishes them from MH (SI Appendix, Tables S13–S16). SH-selected measurements compared with other hominin groups. Krapina and other Neanderthal clavicles: A peculiar morphology? Nevertheless, the curvatures in the coronal plane, in all of the SH specimens where it can be determined, are of type II, as is the case in all Neandertals that we have studied and the few known early Pleistocene specimens. S2). www.pnas.org S7). Comparative morphology and paleobiology of Middle Pleistocene human remains from the Bau de l'Aubesier, Vaucluse, France The pooled sex-weighted mean BM estimated from five adult SH femoral heads is 69.1 kg and is 6.3 kg below the Neandertal mean (75.4 kg) (SI Appendix, Table S4 and Fig. Only one specimen (Scapula IV) displays a ventral sulcus (the most frequent condition in MH). In the SH specimens, the peroneal facet is significantly broader (Fig. F-X (Left) and F-XI (Right) proximal femora in posterior view, showing a low neck angle, large gluteal ridges, and well-developed hypotrochanteric fossae. In contrast, the iliopsoas groove in hip bones of earlier Homo taxa is shallow and does not excavate the medial surface of the AIIS (44). The SH proximal pedal phalanges present hypertrophy of the shaft, and the distal phalanx of the big toe shows an expanded distal tuberosity, as in the Neandertals (39, 52). 2021-01-26T04:14:34-08:00 1A) characterized by very wide sacra, pronounced lateral iliac flaring, and long pubic rami that clearly separate it from the MH pelvic configuration (see below). <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageC]/XObject<>>>/Rotate 0/Thumb 78 0 R/Type/Page>> <>stream Neandertals depart from the SH pattern mainly in having an extreme craniocaudal flattening of the pubic ramus (10, 11, 25, 40). <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageC]/XObject<>>>/Rotate 0/Thumb 42 0 R/Type/Page>> codirected the Atapuerca excavations and research project; J.L.A. aC�/�mA��>� ��P��y��/�ӻ %PDF-1.5 %���� The SH sample shows a dominant dorsal position (n = 8) of the axillary sulcus for the Musculus teres minor (on the axillary border), resembling the predominant condition in Neandertals. The SH pelvises are characterized by their marked robusticity (e.g., large sacroiliac joint, iliac tubercle, and ischial tuberosity) and large overall dimensions. Additional information on the materials and methods for stature, body mass, intrapopulational size variation, and encephalization quotient can be found in SI Appendix). The higher EQ of the SH population compared with the published values in the early Pleistocene Dmanisi hominins (37) demonstrates that the increase in brain size in SH was not simply a consequence of an increase in body mass (29). This research received support from the SYNTHESYS Project www.synthesys.info/, which is financed by European Community Research Infrastructure Action under the FP7 integrating Activities Programme. The pronounced maxillary incisor beveling of Aubesier 4 helps to extend the antiquity of nondietary use of the anterior dentition. The overall stature [(male mean + female mean)/2] of the SH hominins (163.6 cm) is 3.0 cm taller than the mean stature in Neandertals (160.6 cm) (SI Appendix, Table S3). Different anatomical parts display different levels of variation with between 6.1 and 98.2% of the samples of the same size randomly generated from large samples of MH presenting more variation than in SH. SH shares many postcranial anatomical features with Neandertals. 1 A–C and SI Appendix, Table S24) (54, 55). 2007). To avoid methodological problems in estimating body size parameters in the genus Homo, we have generally used the raw values for femoral length, BIB, and FHD as proxies for stature, body breadth, and weight in our comparisons with other fossils (Fig. http://dx.doi.org/10.1073/pnas.1514828112 The unexpected new chronology of this puzzling specimen in the mid of the Middle Pleistocene, led us to conclude that, “the morphology of the human calvarium from Ceprano – which lacks Neanderthal traits and does not have a real counterpart among the continental penecontemporaneous fossil record – [points out to] more complex scenarios of human evolution in … This suggests that the SH hominins, like Neandertals, had a larger costal skeleton relative to their stature compared with MH (see below). The calcanei of Neandertals are broad with a projected sustentaculum tali and a long calcaneal tuber (39). www.pnas.org Thus, the full suite of Neandertal features did not arise all at once, and the evolution of the postcranial skeleton could be characterized as following a mosaic pattern. The middle Pleistocene Sima de los Huesos (SH) fossil collection provides the rare opportunity to thoroughly characterize the postcranial skeleton in a fossil population, comparable only to that obtained in the study of the Neandertal hypodigm and recent (and fossil) modern humans. In sum, SH offers the best proxy for the general postcranial size and shape of Homo for at least the past 1 million years until the appearance of MH. (E) Percentage of cortical area in the right and left humeri and femora. 60/femoral maximum length × 100). At least 28 individuals of both sexes and diverse ages at death (18) were preserved, fragmented, and mixed with carnivore bones, mainly of Ursus deningeri (19). endobj The total length of the sacrum and of the complete hip bone, and of the ischium, ilium, and pubis, the vertical acetabular diameter, and the breadth of the ilium and sacrum are conspicuously above MH (SI Appendix, Table S18). (C) First metacarpal (MC1). Therefore, these traits do not phylogenetically relate the SH population with Neandertals. Direct evidence, based on femoral head size, of heavier bodies appears later, during the middle Pleistocene (including the SH population) and is retained in Neandertals. EP1: 2.0–1.8 Mya early Pleistocene Homo; EP2: 1.7–0.8 Mya early Pleistocene Homo; MP: non-SH middle Pleistocene Homo; Ne: Neandertals; MH: modern humans. 2A and SI Appendix, Tables S11 and S12 and Figs.

See SI Appendix for raw data. CRISPR-Cas9 gene editing can improve the effectiveness of spermatogonial stem cell transplantation in mice and livestock, a study finds. These could be Neandertal specializations, but the scant fossil record of postcranial elements in early Pleistocene Homo makes it difficult to establish a clear cladistic polarity for many anatomical features, such as the morphology of the axis, the proximal humerus, the ulna, or the tibia. Acrobat Distiller 10.0.0 (Windows) Contrary to previous suggestions that middle Pleistocene humans were more dimorphic (35, 36), the SH hominins do not show an unusual degree of size variation compared with MH. The permanent molars from the Denisova Cave show complex occlusal morphology (1, 12, 13). The SH hominins show the following: (i) wide bodies, a plesiomorphic character in the genus Homo inherited from their early hominin ancestors; (ii) statures that can be found in modern human middle-latitude populations that first appeared 1.6–1.5 Mya; and (iii) large femoral heads in some individuals, a trait that first appeared during the middle Pleistocene in Africa and Europe. The SH femora show the plesiomorphic morphological pattern found in most earlier members of the genus Homo (45⇓–47). A mosaic pattern was also documented in the SH cranium (16) although, in this case, the Neandertal suite of derived features forms a single functional complex. (F) Palmar projection of the trapezium tubercle. Significant changes in facial size and robusticity occurred throughout Pleistocene human evolution, resulting in temporal trends in both facial reduction and enlargement. 135 0 obj The dorsoventral size of the single SH complete first rib and an incomplete second rib suggest that the SH hominins had a larger costal skeleton relative to their stature compared with MH (SI Appendix, Table S10 and Fig. Arbortext Advanced Print Publisher 9.1.510/W Unicode 10.1073/pnas.1514828112 Different anatomical parts display different levels of variation with between 6.1 and 98.2% of the samples of the same size randomly generated from large samples of MH presenting more variation than in SH. 5 for H. habilis). Rightmire G.P. Despite subtle variation in Pleistocene hominin tali, some consistent morphological variants can be identified among different fossil samples (27, 49). received financial support from Binghamton University (SUNY) and the American Museum of Natural History; E.P.-R. was supported by a Comunidad Autónoma de Madrid Grant S2010/BMD-2330; and L.R. The curvatures of the SH clavicles in the transverse plane fall within the normal variation in MH. 46 0 obj Thus, the rare Denisovan human remains identified to date show affinity to Middle Pleistocene hominins (2, 12, 13), particularly to those from China and, to a lesser extent, to the Neanderthal lineage . In these two latter traits, the specimens show some variation. Comparative morphology and paleobiology of Middle Pleistocene human remains from the Bau de l’Aubesier, Vaucluse, France Freely available online through the PNAS open access option. Most interpretations of body size and shape in early Pleistocene Homo have relied on one specific individual: KNM WT-15000 (6), which has heavily influenced the view that the wider, more robust Neandertal bauplan was derived from and likely reflected cold adaptation (7). In more derived members of the genus Homo, the bauplan reflects an obligate terrestrial bipedalism with reduced arboreal capabilities. S3). The SH postcranial sample offers an unparalleled opportunity to assess both general aspects of body size and shape and the detailed postcranial morphology, avoiding many of the problems associated with grouping geographically dispersed and chronologically disparate samples. This is consistent with previous hypotheses of an anthropic origin for this accumulation (21). Cranial view of VL2, presenting a very long and dorso-laterally oriented transverse process (arrowhead). Quizlet flashcards, activities and games help you improve your grades. (2002) demonstrated that the main in these hominins, and apply developmental simulations to architectural craniofacial differences between archaic and modern examine how size affects facial features. The fossil evidence suggests that the earliest members of the Homo sapiens clade (Jebel Irhoud, Omo, and Herto) appeared in Africa during the late Middle Pleistocene (1–4).Outside Africa, modern humans appeared much later, during the Late Pleistocene … Significant changes in facial size and robusticity occurred throughout Pleistocene human evolution, resulting in temporal trends in both facial reduction and enlargement.

A few features that have been considered Neandertal-derived traits are also present in the SH hominins, including a low degree of lumbar lordosis, broad distal tuberosities of the manual phalanges, and the wide bases of the lateral metatarsals (MTIII–V), which is consistent with the hypothesis, based on the cranial morphology, that the SH hominins are a sister group to the later Neandertals (16). Astronomers thought they’d finally figured out where gold and other heavy elements in the universe came from. 1 D and E and 2E and SI Appendix, Fig. About 1.6–1.5 Mya some individuals began to show an increase in stature, reaching heights comparable to those present in middle-latitude MH populations.

(2013) invoked evolutionary convergence for the above modern sapiens -like facial morphology in several places and times during the Pleistocene. Regarding the thorax, the absence of complete midthoracic ribs makes it difficult to assess whether the size and shape of the SH costal skeleton is similar to that of Neandertals (32). The detailed postcranial anatomy in SH indicates that some of the potentially derived Neandertal features were not yet present in this population. The metatarsals from SH, Neandertals, and MH are very similar except for the broader base of the lateral metatarsals (MTIII–V), a potentially derived character shared between SH and Neandertals (49). The SH pelvic remains are also distinct from MH in having an anteriorly located acetabulocristal buttress, a well-developed supraacetabular groove and a thin and rectangular, plate-like superior pubic ramus that contrasts with the thick and stout pubis of MH (10, 25) (SI Appendix, Figs. A comparative study, Out of Africa: Modern human origins special feature: The origin of Neandertals, Neandertal roots: Cranial and chronological evidence from Sima de los Huesos. Despite large periods of morphological stasis in the general body plan, the anatomical details of the postcranial skeleton, as revealed in the SH sample, offer the best evidence for a pattern of mosaic evolution in the postcranium within the Neandertal lineage. Online ISSN 1091-6490. Interpreting Middle Pleistocene hominin morphology in this way leads to the conclusion that all early Middle Pleistocene fossils belong to the same lineage in a single species called “Homo heidelbergensis”.

This character has been related to a more lateral and higher position of the scapulae (see below). Later, some populations moved north to Europe where cold adaptation eventually led to the evolution of H. neanderthalensis. Within the genus Homo (excluding the enigmatic and insular species Homo floresiensis), different bauplans could be present among early representatives, but among the more derived representatives of the genus, two distinct bauplans can be differentiated based upon the body breadth and overall robusticity, with Neandertals showing a “wide” bauplan and modern humans showing a “narrow” bauplan. It is apparent from the suite of Neandertal lineage features present in the Aubesier Middle Pleistocene human remains that they provide further evidence for the gradual emergence during the second half of the Middle Pleistocene and the early Late Pleistocene of Europe of the derived (at least in frequency) Neandertal morphological pattern. Am J Phys Anthropol. Thus, the bauplan in the genus Homo seems to have been characterized by a long period of stasis during which the “wide” (with respect to their stature) body plan shared by different Homo species (including the SH hominins) varied rather little throughout the Pleistocene until the appearance of the new “narrow” bauplan in H. sapiens (10, 25, 26). In order to better evaluate the modern human-like facial fea-tures on ATD6-69 several issues need to be clarified. Author contributions: J.L.A., J.M.B.d.C., and E.C.
