Author summary Based on genome-wide genotype data on over 1000 samples from eleven ethnic groups present in Iran and by comparison to reference data sets of both extant populations and ancient DNA samples, we show that the Iranian population comprises distinct genetic variation with respect to populations in close geographic proximity, a cluster of genetically largely overlapping ethnic groups as well as a number of strongly admixed groups. These observations, also corroborated by f3 migration statistics and other approaches, indicate genetic continuity of and limited influx into the cluster groups over several millennia, despite Iran’s geographic position at a crossroads in West Asia. They also suggest, correspondingly, several instances of language adoption instead of demic replacement in the past. Future human genetic studies, both with a focus on population and medical genetics, will have to consider differences in heterogeneity, consanguinity and degree of admixture between the ethnic groups for an adequate…
