In central Asian steppe, the transition to Iron Age is marked on the archeological record by the emergence of several nomad cultures across the steppe. These cultures are often collectively referred to as Scythians and went through a transition from a sedentary to a nomadic cattle-breeding lifestyle, contrasting with preceding Bronze Age populations. It has been suggested that two main admixture events during the end of Bronze Age gave rise to two distinct Iron Age gene-pools emerging Altai and the Urals regions, respectively. The current project aims to test proposed hypothesis and further enlighten the genetic pre-history of current day Kazakhstan. With these aims, we produced ancient genomes of 74 individuals (average of 2.5X coverage, which 39 samples have a coverage > 1X).
