Undertaken here is a multidimensional craniometric analysis of more than 254 ethnic groups of the Neolithic and Bronze Ages from the territory of Eurasia. On the basis of the received information, cluster analysis was done and has shown the genetic condensations of ethnoses and vectors of relatives or, conversely, distinctions between them.
Craniometric and odontologic investigation of the Bronze Age is interesting and in connection with discussion about the origin of Indo-Europeans and about the place of their ancestral home. Different aspects of the problem of the ancestral home of Indo-Europeans are far from completely resolved and generate lively debate in the pages of scientific publications.
New anthropological data allowed identification of alien Mediterranean characteristics influencing various ethnic Eurasian groups and revealed evidence of a migratory stream from the Armenian highlands and the Caucasus. This research provided new evidence of patterns of ethnic contact and intermixture in Western Eurasia.
One can see a clear link between the Armenian highlands samples and the Western Europe samples (the Arcvakar sample – 17 close phenetic links are revealed). The samples from the Georgia (Samtavro /Late Bronze Age – II period) and Iran (Tepe Gissar III), Uzbekistan (Sapallitepe) are identified as the samples with closest affinities samples from Ukraine (Shirochanski) and Poland, Germany (Corded Ware culture) in particular.
This suggests that some of the European genes do actually stem from this area. So, mediterranean connections from Armenian highlands, Georgia and Central Asia are distinctly fixed in Western Europe and in the Middle-Late Bronze Age.
If true, it is suggested that the dispersal of the Indo-European languages have been accompanied by migration and some gene flow from the Armenian highlands homeland to the various historical seats of the Indo-European languages. The different rates of genetic drift and external gene flow may have contributed to the morphological differentiation and diversification amongst the different Eurasian populations.
Cluster analysis has revealed a craniological series having analogies (on a complex of craniometric, odontologic characters) with representatives of the population of the Armenian highlands, the Caucasus, the Near East and Central Asia. The initial starting area (or one of the intermediate areas), as indicated by the anthropological data, would seem to be the Armenian highlands, and the Caucasus as a whole.
