长期以来，考古学家一直在争论 11 至 14 世纪密西西比卡霍基亚政体区域互动的作用。建筑风格、异国情调的材料和文化物品为文化互动以及种族和社会多样性提供了间接证据；然而，识别个人（而不是物质）的流动是我们不断了解人口历史的关键，正是人口历史促成了这一独特政体的形成。这项研究首次使用人类牙釉质的锶同位素分析 (87Sr/86Sr) 来识别卡霍基亚的移民。现代和考古动物群被用来为卡霍基亚周围的美国底部地区建立锶同位素比率的“局部”基线范围。对埋葬在该地区不同停尸地点（包括土堆）的个体的牙齿进行了分析，并与当地的锶同位素范围进行比较，以识别非本地来源的个体。所有分析的个体中有三分之一被确定为非本地人，其锶比率的范围和变异性表明其来自多个地方。同位素数据与现有的生物学和太平间证据的相关性使我们能够研究移民在密西西比政体历史中的作用。
Archaeologists have long debated the role of regional interaction in the 11th to 14th centuries at the Mississippian polity of Cahokia. Architectural styles, exotic materials, and cultural objects provide indirect evidence for cultural interaction and ethnic and social diversity; however, identifying the movement of individuals (rather than materials) is key to our growing understanding of the population history that enabled the formation of this unique polity. This study is the first to use strontium isotope analysis (87Sr/86Sr) of human tooth enamel to identify immigrants at Cahokia. Modern and archaeological fauna were used to establish a baseline “local” range of strontium isotope ratios for the American Bottom region surrounding Cahokia. Teeth from individuals interred in diverse mortuary locations, including mounds, within this region were analyzed and compared to the local strontium isotope range to identify individuals of non-local origin. One-third of all individuals analyzed were identified as non-local, and the range and variability of their strontium ratios suggests multiple places of origin. The correlation of isotopic data with available biological and mortuary evidence allows us to examine the role of migration in the history of this Mississippian polity.
