Dental Affinities of The Irmen People,Western Siberia

Dental features of the Late Bronze Age Irmen population of Western Siberia (14th–10th centuries BC) were studied on the basis of cranio-dental remains from 23 cemeteries in the Kuznetsk Basin, Baraba forest-steppe, the forest-steppe zone of the Altai, Tomsk and Novosibirsk areas of the Ob basin. The results suggest that the Irmen people originated in the Novosibirsk and Baraba areas from a mixture of Andronovo (Fedorovka) and autochthonous groups. Dental data are inconsistent with the idea that the Karasuk tribes might have taken part in this process. The Karasuk people clearly descended from the Okunevo people, as evidenced by the elevated frequencies of the Carabelli cusp and deflecting wrinkle. None of these traits is present in the Irmen people, who display dental gracility evidently introduced by Andronovo (Fedorovka) tribes.
