The genetic snapshot from 11 individuals dated 3785–3359 BCE offers a focused but limited view. Mitochondrial haplogroups are dominated by K (5 individuals) with smaller counts of T (2), H (1), U (1) and W1 (1). Haplogroups K and T are commonly associated in the literature with early European farmers deriving ancestry from Anatolian Neolithic populations; their prevalence here is consistent with an agricultural donor population shaping maternal lineages.
The presence of U and H lineages—H widespread later in Europe and U frequently seen in Mesolithic hunter-gatherers—suggests some continuity or assimilation of earlier lineages, but small counts (especially singletons) require caution. Notably, Y-chromosome haplogroups are not reliably reported in this set, so male-line patterns remain unresolved. Without robust autosomal and Y-chromosome coverage, it is premature to infer proportions of Anatolian farmer, local Mesolithic, or later Steppe-related ancestry in these individuals.
Archaeogenetic context: given the date range (mid 4th millennium BCE) and regional trajectories, a predominantly Neolithic farmer-derived autosomal profile is plausible, with variable local hunter-gatherer contribution. Large-scale shifts associated with Steppe-related ancestry appear later in northwest Europe (~3rd millennium BCE), so these megalithic individuals are crucial for understanding pre-Steppe population structure. Because sample count is modest (n=11), all genetic interpretations should be treated as preliminary and testable with expanded datasets.
