Ancient DNA from Aghitu currently consists of three mitochondrial genomes, each yielding distinct maternal lineages: W (1), T2h (1), and H (1). These mtDNA haplogroups are broadly distributed across West Eurasia in antiquity and the present day. Haplogroup H is widespread in Europe and the Near East; W and T2 subclades are often associated with demographic movements across Eurasia, including steppe and Anatolian connections.
Importantly, no robust Y-chromosome signal is available from these three individuals, so paternal lineages remain undetermined. With a sample count of three (<10), any population-level interpretation must be treated as preliminary. The maternal diversity observed is consistent with a region acting as a conduit for people and maternal lineages rather than demonstrating sharp genetic discontinuity.
When combined with archaeological evidence, the genetic data tentatively support a model of local continuity punctuated by gene flow from neighboring regions. This pattern would align with the high mobility implied by material culture—trade, marriage, and small-scale migrations—seen across the Armenian Highlands during the Late Hellenistic era. Future sampling, especially male lineages and genome-wide data, is essential to test hypotheses about ancestry, admixture, and demographic change.
