While we have a deep understanding of human migration and history in some regions of the planet, the peopling of the Americas is still relatively under-studied. With support from SBE-BCS-Biological Anthropology and the Office of Integrative Activities' NSF 2026 Fund Program and Established Program to Stimulate Competitive Research (EPSCoR), Drs. Alfonso-Durruty (Kansas State University), Misarti (University of Alaska Fairbanks), and Bolnick (University of Connecticut) will use skeletal, genetic, dietary and archaeological data to examine two distinct ecological adaptations, terrestrial and marine hunting/gathering, that are highly specialized and appear in the archaeological record at different times. By using multiple sources of information, this study will effectively expand our knowledge and understanding of the Indigenous Peoples of a remote region of the Americas. The project will foster international scientific research collaborations, engage with local communities, and provide training, mentoring, and learning opportunities to undergraduate and graduate students in subjects such as the production of 3D analogs and 3D digital data, database design and management, scientific communication and dissemination, molecular anthropology, and the chemical (stable isotope) analyses of bone for dietary reconstructions. The project also will address two of the top thirty-three NSF 2026 Idea Machine entries: “Designing Ecosystems for the Future” and “Reversibility: Future of Life on Earth." This study will utilize biodistance markers, stable isotope data, next-generation genome sequencing, radio-carbon dating, and statistical methods to estimate biodistance, compare and evaluate diets, and reconstruct the population history of indigenous groups. The data will be analyzed to determine whether or not pre-contact terrestrial and marine groups had different origins, or whether the earlier terrestrial hunter gatherers eventually gave rise to marine groups. The extended period of time covered by the data to be collected will allow for reconstruction of the dynamics involved in the population history of a remote region of the Americas.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.

尽管我们对地球某些地区的人类移民和历史有深刻的了解，但美洲人民仍然相对研究。在SBE-BCS生物学人类学和综合活动办公室的支持下，NSF 2026基金计划和建立的计划刺激竞争研究（EPSCOR），DRS。 Alfonso-Durruty（堪萨斯州立大学），Misarti（阿拉斯加Fairbanks大学）和Bolnick（康涅狄格大学）将使用骨骼，遗传，饮食和存档数据来检查两种不同的生态适应，地形和海洋狩猎/收集，在不同的时代出现在不同的时代中，这是高度专业的，并且在不同的时间出现在不同的时代中。通过使用多种信息来源，这项研究将有效地扩展我们对美洲偏远地区土著人民的知识和理解。项目将培养国际科学研究合作，与当地社区互动，并为本科和研究生提供培训，心理和学习机会，例如生产3D模拟和3D数字数据，数据库设计和管理，科学交流和分散，分子人类学和化学（稳定的同位素）分析型型型型的学科。该项目还将解决33个NSF 2026 Idea Machine条目中的两个：“为未来设计生态系统”和“可逆性：地球上的生活未来”。这项研究将利用生物固定标记，稳定的同位素数据，下一代基因组测序，无线电碳测年和统计方法来估计生物固定，比较和评估饮食，并重建本地群体的人口历史。将对数据进行分析，以确定前接触陆地和海洋群体是否具有不同的起源，或者早期的陆地猎人收集者最终是否会引起海洋群体。要收集的数据所涵盖的较长时间将允许重建美洲偏远地区人口历史的动态。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛影响的审查标准通过评估来通过评估来获得支持的。
