To test the competing hypotheses as to the origin of the Okunev culture, four male cranial series from Okunev cemeteries in the Minusinsk Basin were compared with 23 other pre-Andronovo series from southern Siberia, and 45 Early and Middle Bronze Age groups from Eastern Europe (24 Yamnaya and 21 Catacomb), using multivariate statistical analysis. While the Afanasyevo admixture in the Okunev population is possible, the hypothesis that the Okunev culture of the Minusinsk Basin originated from the second migration from the Eastern European steppes to southern Siberia in the Early Bronze Age is not supported. It could, however, be applied to people associated with the Okunev-type (Chaa- Khol) culture in Tuva, although these may as well have descended from the Afanasyevans. As concerns the Minusinsk Basin and other regions of southern Siberia except Tuva, the fi ndings agree with the idea of a marked evolutionary conservatism peculiar to the autochthonous populations of that territory, as evidenced by the fact that each of the three Early Bronze Age population clusters—on the Yenisei, in the Altai, and in Baraba—has its own Neolithic ancestors in the same area (this does not concern the Chaa-Khol, the Yelunino, and apparently the Samus populations). The immediate ancestors of the Okunev people can be identifi ed with the Neolithic population of the Krasnoyarsk-Kansk area, and more distant ones with the Upper Paleolithic southern Siberian common ancestors of the Okunev people and the Native Americans. These ancestors are evidenced by both cranial data (indirectly) and genetic data (directly). The la tter suggest that among these common ancestors were the Malta boy and the Afontova Gora II male. The Okunev population, then, is a relic, offeri ng us a unique opportunity to see what the Upper Paleolithic ancestors of the Native Americans may have looked like in their southern Siberian homeland.

The paleogenetic study of Bertek-33, an Afanasyevo cemetery on the Ukok plateau, the Altai Mountains
Статья
We present the results of a paleogenetic analysis of bone samples representing seven adult individuals from Bertek-33—an Afanasyevo cemetery on the Ukok plateau, in the Altai Republic, Russia. The fi ndings are interpreted with reference to archaeological and anthropological data. Four systems of genetic markers were analyzed: mitochondrial DNA, polymorphic fragment of the amelogenin gene, autosomal STR-loci, and Y-chromosomal STR-loci. Genetic results indicate the dominance of Western Eurasian mtDNA haplogroups (T, J, U5a, K, H) and the homogeneity of the male gene-pool represented by variants of the Y-chromosomal haplogroup R1b. Data on mtDNA, Y-chromosome, and individual autosomal markers attest to the Western Eurasian affi nities of this group. The sample falls within the mtDNA and Y-chromosomal diversity of the Afanasyevo population of southern Siberia. Possible kinship between the individuals buried at Bertek-33 is discussed. Also, we address theoretical issues such as the accuracy of comparisons and the interpretation of genetic data with regard to cultural features.

Measurements of ~730 male crania from cemeteries associated with Bronze Age cultures of the steppe and foreststeppe zone of Eastern Europe (Yamnaya, Catacomb, Poltavka, Babino, Lola, and Timber-Grave) were subjected to multivariate analyses. D2 distances between sample centroids were calculated, and non-metric multidimensional scaling was carried out. The results are used to evaluate the proportion of indigenous and immigrant groups during four successive periods—Early Bronze Age, Middle Bronze Age, Middle to Late Bronze Age transition, and Late Bronze Age. The differences between Yamnaya populations are comparable to those between recent groups inhabiting vast territories of Eastern Europe, from Karelia to the Northern Caucasus. The ro le of the substrate component in the origin of Early and Middle Bronze Age groups was considerable. However, virtually no continuity was observed at the Middle to Late Bronze Age transition, when post-Catacomb cultures originated. Continuity with Middle Bronze Age groups is observed in Late Bronze Age samples representing the Timber-Grave people, who combined features of the Catacomb and post-Catacomb people. Factors accounting for such a process may include “pendulum migrations” and temporary reversal of funerary tradition from kurgans to “invisible” fl at burials.
