Analysis of mitochondrial DNA obtained from skeletal materials can be used to examine the relatedness of long extinct populations. This award will be used to investigate the biological relationships of four populations, totaling approximately 75 individuals, located in the Great Lakes region, as well as indicate some aspects of demographic history that are reflected in the pattern of genetic diversity. This investigation will test ancestral relationships proposed by linguists and archaeologists regarding the relationship between the diverse and expanding populations of the Archaic and Woodland periods in this region. Specifically, this study will test the genetic relationships within Glacial Kame and Red Ocher populations, as well as between these and Old Copper, Mississippian, and modern Algonquian speaking populations in the lower Great Lakes region. This study can help determine if archaeological similarities were primarily the result of cultural spreads or population expansions, in addition to estimating the extent of genetic differentiation that existed in the Great Lakes during the last 4000 years. The mtDNA of populations included in this study will also be compared with that of other ancient populations of the Lower Great Lakes region including Archaic Indian Knoll, early Woodland Adena, Hopewell, and Late Prehistoric Fort Ancient populations, all previously or currently being studied. In addition, data generated from this study will contribute to the growing body of information that can be used to address broader questions regarding the peopling of the New World.

对从骨骼材料中获得的线粒体 DNA 进行分析可用于检查长期灭绝种群的相关性。 该奖项将用于调查位于五大湖地区的四个种群（总共约 75 个个体）的生物学关系，并指出遗传多样性模式所反映的人口历史的某些方面。这项调查将测试语言学家和考古学家提出的关于该地区古风时期和林地时期多样化和不断扩大的人口之间关系的祖先关系。具体来说，这项研究将测试冰川龟和红赭石种群内的遗传关系，以及这些种群与五大湖下游地区的古铜语、密西西比语和现代阿尔冈昆语种群之间的遗传关系。这项研究除了估计过去 4000 年来五大湖区存在的遗传分化程度之外，还可以帮助确定考古学上的相似性是否主要是文化传播或人口扩张的结果。本研究中包含的种群的 mtDNA 还将与下五大湖地区其他古代种群的 mtDNA 进行比较，包括古印第安诺尔、早期林地阿德纳、霍普威尔和史前晚期古堡种群，所有这些都是以前或目前正在研究的。 此外，这项研究产生的数据将有助于提供越来越多的信息，这些信息可用于解决有关新世界人口的更广泛问题。
