The Armenia_LBA dataset comprises 47 individuals dated to 1439–805 BCE from cemeteries including Karashamb, Lori Berd, Nerkin Getashen, Tekhut, Keti, Noratus, Sarukhan and Kapan. Mitochondrial DNA diversity is notable: haplogroups U (8 individuals), T (5), K (4), J (4) and N (3) are the most common. These maternal lines reflect a mixture of deep Caucasian/European hunter-gatherer-associated lineages (U) and haplogroups widespread in the Near East and Anatolia (T, K, J), consistent with archaeological signals of long-term regional continuity and exchange.
Y-chromosome diversity in the dataset is sparse: single occurrences of haplogroups I, R and J are recorded. Because Y-sample counts are low and represent a minority of the total, interpretations about male-mediated migration must remain cautious. The autosomal profiles of Armenia_LBA individuals broadly indicate ancestry components typical of the South Caucasus Late Bronze Age — a blend of local Caucasus/Near Eastern ancestry with varying input related to populations carrying steppe-derived ancestry farther north. This pattern fits genomic clines seen across Bronze Age West Eurasia: local continuity punctuated by gene flow from neighbouring regions.
While 47 samples offer a meaningful window, geographic sampling is uneven and some lineages remain rare; therefore, population-level inferences should be framed as provisional. Future sampling from settlements and additional male remains would sharpen our understanding of sex-biased processes, kinship, and mobility in the Armenian highlands.
