Sixteen DNA samples from Popova zemlja provide a window into the biological makeup of a Middle Neolithic Croatian community. The autosomal signal is dominated by ancestry related to Anatolian Neolithic farmers, consistent with the wider Neolithic expansion into Europe. However, admixture with local Western Hunter‑Gatherer (WHG) groups is detectable, producing a genetic gradient rather than a binary replacement. The dataset is moderate in size; while informative, conclusions should be seen as provisional pending larger sampling.
Uniparental markers add nuance: Y‑chromosome haplogroups include I (two individuals), G (two individuals), and J (one individual). Haplogroup G is often associated with early farming groups across Europe, whereas I can reflect continuity with indigenous hunter‑gatherer male lineages or later local differentiation. The presence of J, though less common, attests to genetic variation and possible long‑distance connections. Mitochondrial lineages are dominated by K (five individuals), with additional N (three), H (two), U (two) and T (two). Haplogroup K and subclades of N and T are frequently observed in early farmer populations, while H and U reflect broader European maternal diversity.
These genetic patterns align with an archaeological narrative of incoming agricultural communities integrating with local populations. Still, with 16 samples, fine‑scale demographic events (sex-biased migration, kinship structures, or temporal changes) remain difficult to resolve. Future targeted sampling and high-resolution sequencing will sharpen the picture.
