Economic exchange, cultural transformation, and social complexity are heavily influenced by migration and movement of people. This research seeks to use ancient DNA (aDNA) to better understand such influences in regions with limited previous cultural study. Based on the genetic ties between various sites, it will be possible to address questions of how individuals moving between the different sites, and into other regions, reflect changes in the archaeological assemblages that have been excavated. This, in turn, can help to better understand today’s shifts and changes that have been brought about by the movement of individuals and mixing of cultures which occur so frequently. Radiocarbon dating for samples from the sites will also allow for refining the history of the region and modeling cultural changes and dynamics. Additionally, two students will attend a month-long summer course that will introduce them to the field of ancient DNA and the required laboratory techniques. Due to the lack of widespread ancient DNA facilities, this will allow for helpful training and grounding for future work and collaboration. Because the world has always been connected through the movement of people, exchange of goods, and sharing of cultural traits, the evidence of such can be found within the genomes of individuals as well as in the archaeological sites they leave behind. The present research is comprised of multiple lines of inquiry that address questions on gene flow, genetic variation, migration, trade, and interaction among societies. Whole mitochondrial DNA genomes (mitogenomes) will be sequenced for the individuals in order to assess the relationship between DNA and intermigration and intermarriage patterns as evidenced by material culture.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

经济交流、文化转型和社会复杂性很大程度上受到人口迁移和流动的影响。 这项研究旨在利用古代 DNA (aDNA) 更好地了解先前文化研究有限的地区的此类影响。 基于不同遗址之间的遗传联系，将有可能解决个体如何在不同遗址之间移动以及进入其他地区的问题，从而反映已发掘的考古组合的变化。反过来，这可以帮助我们更好地理解当今频繁发生的个人流动和文化融合所带来的转变和变化。对这些地点的样本进行放射性碳测年也将有助于完善该地区的历史并模拟文化变化和动态。此外，两名学生将参加为期一个月的夏季课程，向他们介绍古代 DNA 领域和所需的实验室技术。由于缺乏广泛的古代 DNA 设施，这将为未来的工作和合作提供有用的培训和基础。由于世界始终通过人员流动、货物交换和文化特征共享而联系在一起，因此可以在个体的基因组以及他们留下的考古遗址中找到这些证据。目前的研究由多方面的调查组成，涉及基因流动、遗传变异、迁移、贸易和社会间互动等问题。将对个体的整个线粒体 DNA 基因组（线粒体基因组）进行测序，以评估 DNA 与物质文化所证明的通婚和通婚模式之间的关系。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
