Lower Limb Diaphyseal Cross-Sectional Geometry of Near Eastern Middle Paleolithic Hominids

摘要P.I.Erik Trinkaus SBR-9318702最近，人们清楚地看到，在近东，旧石器时代中期，有两个相当独特的、在形态上有定义的原始人-尼安德特人(或与欧亚尼安德塔人有亲缘关系的晚期古人类)和健壮的早期现代人。晚期古人类不仅在头骨特征上与欧洲尼安德特人相似，而且在骨骼其余部分的一系列特征上也相似，其中大部分似乎与整体粗壮有关，与其他后来的古人类共享。相比之下，近东早期现代人的样本比晚期古人类样本更接近现代人类的骨骼形态。这项研究要解决的问题是，这两种血统可能具有哪些显著的行为差异(如果有的话)？对于不同可能的习惯性行为，有许多线索，但Trinkaus将专注于一个相关的方面，即腿骨的大小和形状，这与运动活动的差异有关(这意味着更像尼安德特人的人拥有更厚、更强壮的腿骨，并且从事更剧烈的习惯性活动模式)。无论拟议的研究结果如何，它都将进一步洞察近东现代人起源的动态，近东是见证我们称为早期现代人的人口的最早地区之一。因此，这项工作将有助于理解更多关于现代人起源的全球问题，而近东只提供了一个区域例子。*P\a nthro\jfred\9318702.absV X=？！D(Times New Roman符号&amp；Arial 5“h，5%，5%=Jonathan Friedlaender Jonathan Friedlaender

ABSTRACT P.I. Erik Trinkaus SBR-9318702 Recently, it has become clear that in the Near East, in the Middle Paleolithic, there were two rather distinctive, morphologically defined hominids - the Neanderthals (or late archaic humans with affinities to the Eurpoean Neandertahls) and robust early modern humans. The late archaic group not only resembles the European Neanderthals in cranial features, but also in a suite of features from the rest of the skeleton, most of which appear to be related to overall robusticity, shared with some other later archaic humans. By contrast, the Near Eastern early modern human sample more closely approaches Recent human skeletal morphology than does the late archaic sample. The issue to be addressed by this research is to what, if any, significant behavioral differences might these two lineages possess? There are a number of clues to the different possible habitual behaviors, but Trinkaus will focus on one relevant aspect, leg bone size and shape, as related to differences in locomotor activity (the implication is that the more Neanderthal - like individuals possessed thicker, more robust leg bones, and were engaged in more strenuous patterns of habitual activity). Whatever the outcomes of the proposed research, it will provide further insight into the dynamics fo the origins of modern humans in the Near East, one of the earliest regions to witness populations we call early modern humans. The work will therefore contribute to understanding more global issues of the origins of modern humans, for which the Near East provides only one regional example. *** P\a nthro\jfried\9318702.abs V X = ? ! ! ! ! !
