Archaeological and ethnohistorical documents suggest that the Chachapoya region was inhabited by a number of distinct sociopolitical groups that only united in the face of their common enemy, the Inka. The purpose of this research is to quantify the amount of internal genetic differentiation and levels of extraregional gene flow during the Late Chachapoya period, in order to obtain a better understanding of the genetic relationship between these presumed ethnic groups. Craniometric data were collected from three Late Chachapoya samples (Laguna Huayabamba, Kuelap, and Laguna de los Cóndores), in order to understand the genetic relationships between the groups and facilitate our understanding of Late Chachapoya population structure. Genetic differentiation among these series ranged from 0.047 (heritability = 1.0) to 0.090 (heritability = 0.55). The Relethford-Blangero residuals indicate that the Laguna Huayabamba and Laguna de los Cóndores populations were receiving greater than average external gene flow, while Kuelap was receiving less than average external gene flow. The correspondence between biological and archaeological data in the investigation of prehistoric ethnic identity is discussed.
考古学和民族历史文献表明，查查波亚地区曾居住着多个不同的社会政治群体，这些群体仅在面对共同敌人印加人时才联合起来。本研究的目的是量化查查波亚晚期的内部基因分化程度和区域外基因流动水平，以便更好地理解这些假定民族群体之间的基因关系。为了了解这些群体之间的基因关系并促进我们对查查波亚晚期人口结构的理解，从三个查查波亚晚期样本（瓦亚班巴湖、库埃拉普和孔多雷斯湖）收集了颅骨测量数据。这些系列之间的基因分化范围为0.047（遗传率 = 1.0）至0.090（遗传率 = 0.55）。雷勒思福德 - 布兰杰罗残差表明，瓦亚班巴湖和孔多雷斯湖群体接受的外部基因流动高于平均水平，而库埃拉普接受的外部基因流动低于平均水平。本文讨论了在史前民族身份调查中生物学数据与考古学数据之间的对应关系。
