Incidences of Nonmetric Cranial Variants in Several Population Samples from East Asia and North America

Abstract

Incidence data of nonmetric cranial variants were presented for the Mongolian, Alaskan Eskimo, Canadian Eskimo, Aleut, Ontario Iroquois, Japanese, and Ainu samples. Since the SMITH'S MMDs based on the data of male series were highly correlated with those based on the data of pooledsex series, the latter MMDs were employed for interpopulation comparisons. The results of the cluster analysis and principal co-ordinates analysis faithfully reflected the population relationships so far known. The Ainu series was isolated from all the modern Mongoloid series compared. It was stressed that nonmetric analyses of Aeneolithic Yayoi crania are needed for further elucidation of the population history of Japan.
