Genetic data from Nazarlebi is tantalizing but very limited: three individuals dated to 1500–1000 BCE provide the basis for preliminary inferences. Y-chromosome results include IJ in one sample and I in another; mitochondrial results include haplogroup K in two samples and N in one. These markers are informative at a broad level but cannot by themselves resolve fine-scale ancestry or population dynamics.
Haplogroup IJ is ancestral to branches common across West Eurasia and its presence at Nazarlebi is broadly compatible with paternal lineages seen in the Caucasus and adjacent regions during the Bronze Age. Haplogroup I, often associated with European hunter-gatherer-descended lineages, may reflect local or regional substrate ancestry; however, interpretations must be cautious without autosomal context.
Maternal lineages K and N are deep West Eurasian branches: K is frequently detected in Neolithic and Bronze Age contexts across Europe and the Near East, while N encompasses early Eurasian diversity. Together these mtDNA results hint at genetic continuity and connections with wider West Eurasian pools, but the small sample count (<10) makes all conclusions preliminary. Archaeological correlation, additional genome-wide sequencing and more samples from Kakheti are required to clarify admixture, migration or kinship patterns.
