摘要：The incidence of nonmetric cranial traits in the Pre-Columbian Peruvians from the Chancay site was examined, and their affinities with several Mongoloids, in particular with the other American Indians were determined by comparison of nonmetric data. Distance analyses based on the MMDs demonstrated that in company with the Ontario Iroquois and the Chicama, the Chancay form a cluster of the native American Indians, which is the most distant from the cluster of the Jomon and Ainu. Also, the analyses showed that the Chancay have a closer affinity with the Ontario Iroquois, a North American Indian, rather than with the Chicama, another Peruvian. This may suggest that among the American Indians, morphological differentiation of nonmetric traits does not coincide with geographical distance between the archaeological sites.
