虽然美国西南部史前普韦布洛印第安人的人口历史和社会组织在考古文献中得到了关注，但生物人类学家对这一主题的研究很少。在这里，我们使用决定因素比率分析来检查位于新墨西哥州中北部的两个祖传的特瓦印第安人村落的婚后住所。此外，我们还检查了村民之间的遗传关系，以及由于来自区域外来源的基因流动或区域聚集而导致的村民内部的异质性水平。决定因素比分析的结果表明，在普韦布洛内男性的差异更大，这与至少一个Tewa普韦布洛的母系居住地一致。两个普韦布鲁人的异质性低于预期，这表明内婚制可能在一些史前特瓦人中实行过。来自区外来源的基因流动表明，两个不同的群体的群体内异质性大于预期。距离矩阵相关分析表明，表型和地理距离之间的关系很小，这表明地理位置不是基因流动或配偶交换的主要基础。表型和地理距离之间的弱关系可能是以下因素的综合作用：某些地方的内婚制，其他地方的非随机的区外基因流动或迁移，以及有限的非邻近的区域基因流动或迁移，这些可能是建立在基于医学会关系的仪式交换网络上的。
Although the population history and social organization of the prehistoric Pueblo Indians of the American Southwest have received attention in the archaeological literature, little research on this topic has been conducted by biological anthropologists. Here, we examine postmarital residence at two ancestral Tewa Indian pueblos located in north-central New Mexico using determinant ratio analysis. In addition, we examine genetic relationships among pueblos, as well as levels of within-pueblo heterogeneity due to gene flow from extraregional sources, or regional aggregation. Results from determinant ratio analysis indicate greater within-pueblo male variation, consistent with matrilocal residence for at least one Tewa pueblo. Less than expected heterogeneity at two pueblos suggests that endogamy might have been practiced among some prehistoric Tewa pueblos. Gene flow from extraregional sources is indicated for two different pueblos by greater than expected within-group heterogeneity. Distance matrix correlation analyses indicate little if any relationship between phenotypic and geographic distances, suggesting that geography was not the primary basis of gene flow or mate exchange. The weak relationship between phenotypic and geographic distances may be the combined effects of endogamy at some pueblos, nonrandom extraregional gene flow or migration at other pueblos, and limited nonproximity-dependent regional gene flow or migration among pueblos, possibly structured on ritual exchange networks based on medicine society affiliation.
