Ancient DNA from 31 individuals dated to 6500–5600 BCE paints a nuanced genetic portrait of Northwest Anatolian Neolithic communities. Y-chromosome assignments are available for a subset (16 males): haplogroup G is the most frequent (9 mentions), accompanied by H (3), I (2), C (1) and J (1). Mitochondrial DNA calls for 22 individuals show predominance of K (9) and N (7), with smaller counts of T2b (2), J (2) and X (2). These numbers indicate that the Neolithic villages in the Marmara carried the genetic hallmarks often associated with early farmers in Anatolia and adjacent regions.
Interpretation is cautious: Y- and mtDNA counts derive from subsets of the 31 samples, so frequencies reflect the sequenced individuals rather than an absolute census. The prominence of Y-haplogroup G and mtDNA lineages such as K and N is consistent with broader Anatolian farmer ancestry documented elsewhere, supporting archaeological models of demographic expansion of farming groups. The presence of haplogroup I (often seen in European hunter-gatherer contexts) in a small number of samples hints at low-level admixture with local foragers or complex regional ancestries—limited evidence suggests further study is needed. Singleton Y types (C, J) and modest counts of mtDNA variants emphasize that genetic diversity existed and that conclusions about population-level continuity should remain probabilistic rather than definitive.
