COLLABORATIVE RESEARCH: Molecular Perspectives on Aleut Origins

犹他大学PI O'Rourke和堪萨斯大学PI Crawford和West的合作计划是通过遗传学、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。这项拟议的研究建立在先前在阿留申群岛研究现代和古代人口mtDNA的项目的基础上。本项目拟在以往研究的基础上，增加对y染色体多态性的采样和分析。这项研究可能会对史前和现代阿留申人以及其他北美和西伯利亚群体之间进化关系的本质带来更大的科学理解。此外，它将为现代阿留申人口的起源问题提供新的见解，特别是美洲的原始殖民。

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 potentially bring 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.
