COLLABORATIVE RESEARCH: Molecular Perspectives on Aleut Origins

犹他州大学PI O'Rourke和堪萨斯大学PI的克劳福德和韦斯特之间拟议的合作是通过遗传学、考古学和文化人类学方法继续对阿留申人进行跨学科研究。这项研究建立在阿留申群岛以前的一个项目的基础上，该项目着眼于现代和古代人群的mtDNA。本计画拟在先前研究的基础上，增加Y染色体多态性的取样与分析。这项研究可能会带来更大的科学理解的性质之间的进化关系的史前和现代阿留申人和其他北美和西伯利亚群体。此外，它还将为现代阿留申人的起源问题提供新的见解，特别是美洲最初的殖民地。

The proposed collaboration between PI O'Rourke, University of Utah, and PI's Crawford and West, University of Kansas, is to continue interdisciplinary research on Aleut populations through genetics, archaeology, and cultural anthropological methods. The proposed research builds on a previous project in the Aleutians looking at mtDNA in both modern and ancient populations. This project proposes to expand on the previous research with increased sampling and analysis of Y-chromosome polymorphisms. The research will potentiallybring greater scientific understanding of the nature of the evolutionary relationships between prehistoric and modern Aleuts and other North American and Siberian groups. In addition, it will provide new insights into the question of the origins of the modern Aleut population specifically and potentially the original colonization of the Americas.
