This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2).This research uses data from archaeological cemeteries to study the interactions among borderland peoples engaged in power struggles for territory and how impacts by conquerors influence regional population relationships. Previous research has shown that cultural groups respond differently to expansion into their homeland. What is not yet clear is whether biological relatedness correlates with the sharing of cultures and lifestyles that result from these interactions. Specifically, how prominent was the change in regional gene pools as societies became more culturally intertwined? Nevertheless, it is well established that colonized people adopt richly diverse identities despite expectations to culturally integrate. When common regional histories are known, identifying groups with shared genetic relationships provides a key component towards understanding their social identity construction. Closed and unchanging societies have not proven to be the norm in the past, and exploring these concepts archaeologically is important because it questions typological and static ideas about culture. This research provides a reading of the past that finds traction in modern discussions of social identities and self-determination. The project provides open-source data to be shared with other scholars for additional comparative studies. It generates a novel bioarchaeological model for understanding regional relationships and enhances educational and training opportunities for students and mentees. This research uses changes in heritable dental phenotypes as indicators of gene flow, a methodological approach which can be applied in other contexts, with existing data sets, and is non-destructive. Assessment of shared genetic histories is used to determine if contacted populations were subject to biological assimilation. Recognition of unanticipated ancestral ties can be an indication of crafting of identities that flourished in complex ways and encourages archaeological studies to reconsider typological classifications. Only after resolving what is unknown, “how were people related?”, can what is known historically be appropriately applied.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.

该奖项全部或部分根据2021年美国救援计划法案（公法117-2）资助。本研究使用考古墓地的数据来研究边疆民族之间的相互作用，这些民族参与了领土的权力斗争，以及征服者的影响如何影响区域人口关系。以前的研究表明，文化群体对向祖国扩张的反应不同。目前尚不清楚的是，生物相关性是否与这些互动产生的文化和生活方式的共享有关。具体来说，随着社会变得更加文化交织，区域基因库的变化有多突出？然而，众所周知，殖民地人民尽管期望在文化上融合，但仍具有丰富多样的身份。当共同的区域历史是已知的，确定群体共享的遗传关系提供了一个关键组成部分，了解他们的社会身份建设。封闭和不变的社会在过去并没有被证明是常态，从考古学的角度探索这些概念很重要，因为它质疑了关于文化的类型学和静态观念。这项研究提供了对过去的阅读，在现代社会身份和自决的讨论中找到了牵引力。该项目提供开放源数据，与其他学者分享，以进行更多的比较研究。它产生了一个新的生物考古模型，用于理解区域关系，并为学生和学员提供更多的教育和培训机会。这项研究使用遗传性牙齿表型的变化作为基因流动的指标，这是一种可以应用于其他背景下、使用现有数据集的方法，并且是非破坏性的。共同的遗传历史的评估是用来确定是否接触人口受到生物同化。对未曾预料到的祖先关系的承认可能是以复杂方式蓬勃发展的身份的一种迹象，并鼓励考古学研究重新考虑类型学分类。只有在解决了未知的问题之后，“人们是如何联系在一起的？"，该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
