Abstract
Skull dimensions of nine sable populations in Yakutia (n = 1230 ind.) were studied. Differentiation in the dimensional structure between autochthon left-bank (large dimensions) and introduced right-bank (small dimensions) population groups was revealed. Allochthonous groups occupy an intermediate position between the founders (Vitim, Bureya, Kamchatka) and left-bank aboriginals exhibiting morphological trends that lead to the appearance of new forms of the species.
