Genetic Profile
The Bulgaria_N dataset (11 individuals dated 6100–5450 BCE) provides a window into the human biology of early farmers in the central Balkans. Genome‑wide ancestry profiles are consistent with a predominant Anatolian Neolithic farmer component, the hallmark signal of the first widespread agriculturalists in Europe. Superimposed on that main signature is variable input from local Western Hunter‑Gatherer (WHG) ancestry, reflecting admixture between incoming farming groups and resident forager populations. Archaeogenetic models that combine these components best explain the observed allele‑sharing patterns, though regional variation exists.
Uniparental markers in this sample are informative but limited in number. Y‑chromosome haplogroups reported include G (2), C (1), and I (1). Haplogroup G is frequently observed among early European farmers and fits the expected Anatolian‑derived male lineages, while I and C may reflect local or diverse paternal lineages; interpretation is tentative because only a subset of individuals yielded robust Y calls. Mitochondrial diversity (K x2, H x2, H* x1, X2b x1, J x1) mirrors the mitochondrial profiles seen in other Neolithic farmer assemblages where K and H variants are common.
These genetic signals corroborate the archaeological story: migration of farming groups carried material culture and genes into the Balkans, and subsequent interaction with local groups produced blended communities. Because the sample size is modest, further sampling across chronology and space is required to resolve social structure, sex‑biased admixture, and microregional dynamics.
