Human-Environment coevolution in Indigirka (Russian Federation) : frozen graves in present-day autochthonous populations.

HUMAD-MAFSO program focuses on the history of human settlement of Yakutia (Sakha Republic, eastern Siberia) and their adaptation to one of the coldest areas of the planet, located between the Arctic Circle and the Arctic Ocean. The Yakut population is studied from the perspective of the co-evolution of man and infectious/parasitic diseases by analyzing and confrontating archaeological data (frozen tombs excavated in an exceptional state of preservation) to historical, cultural and biological data. The history of the settlement is based on the comparison between ancient and contemporary populations using the same genetic markers. Our approach has a particular interest on sequencing ancient DNA from humans, bacteria and viruses. Our studies on emerging diseases already identified by our laboratory continued by the means of epidemiological surveys on well targeted contemporary populations. Following our study on the human Settlement of the Verkhoyansk region (2010/2012), our new program continues the study of the Yakut settlements in a new ecological region: the basins of the rivers Indigirka, Kolyma and Olenek area (west of the Lena, at the Arctic Circle), focusing on the oldest human settlement phases and using the most recent genomic technologies (complete sequencing of ancient viruses and bacteria). Field and laboratory work are coordinated by a French-Russian bilateral cooperation formalized by the International Associated Laboratory cosie « Coevolution media men in eastern Siberia. »
