Abstract

Craniological intergroup variability of the Neolithic and Early Bronze Age populations of the Baikal region was studied. We used craniometrical data on the Early Neolithic (Kitoi stage), the Late Neolithic (Serovo stage) and the Bronze Age (Glazkovo stage) groups from the Angara, Upper Lena, Southern Baikal and Trans-Baikal territories. The Mahalanobis distance and canonical analysis were used for groups’ comparison. It is shown that by craniometrical data, as well as by non-metric cranial traits data, the Early Neolithic Kitoi groups and the Late Neolithic Serovo groups were carriers of different gene pools. The isolated position of the Kitoi group from Southern Baikal Shamanka 2 burial was revealed. At the same time the similarities were found between the Kitoi group from Angara region and chronologically distant Bronze Age Glazkovo groups from Angara, Upper Lena and Trans-Baikal territories. It is hypothesized that the morphological diversity of Glazkovo groups could be due to their mixing with the descendants of the Kitoi groups who have left the Cis-Baikal region and later migrated back from the neighboring territories. It is assumed that the population of the Trans-Baikal which exhibited extremely stable anthropological composition from the Early Neolithic to the Bronze Age penetrated in Glazkovo stage in the Cis-Baikal region and influenced the formation of the Early Bronze population’s gene pool.
