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

最近，人们已经清楚地认识到，在近东，在旧石器时代中期，有两个相当独特的、形态上明确的原始人——尼安德特人（或与欧洲尼安德特人有亲缘关系的晚期古人类）和强壮的早期现代人。这一晚期古人类群体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与之相似，其中大部分特征似乎与其他一些晚期古人类共有的整体健壮性有关。相比之下，近东早期现代人类样本比晚期古人类样本更接近现代人类骨骼形态。这项研究要解决的问题是，如果有的话，这两个血统可能具有什么显著的行为差异？对于不同可能的习惯行为，有很多线索，但Trinkaus将重点关注一个相关方面，腿骨的大小和形状，因为它们与运动活动的差异有关（这意味着，更像尼安德特人的个体拥有更厚、更强壮的腿骨，并且从事更剧烈的习惯性活动模式）。无论提出的研究结果如何，它都将进一步深入了解近东现代人类起源的动态，近东是最早见证我们称之为早期现代人类的地区之一。因此，这项工作将有助于了解更多关于现代人类起源的全球性问题，近东只是提供了一个区域性的例子。*** P\a nthro\jfried\9318702腹肌​vx = ？!!!!!D (Times New Roman Symbol & Arial 5 " h, 5%, 5% = 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 = ? ! ! ! ! !
