Pre-Slavic Greater Poland

The Pre_Slavic assemblage from Greater Poland unfolds across a vast temporal canvas: early Mesolithic lakeshore foragers (sites such as Kamienskie) give way, intermittently, to Bronze and Iron Age communities clustered around Poznań, Santok, Rumin and Sowinki. Archaeological sequences at Poznań-Śródka and Santok reflect repeated occupation and re-use of riverine landscapes: trade routes along the Warta and Noteć rivers fostered continuity and cultural layering.

Material culture — pottery styles, burial rites, and settlement traces attributed by archaeologists to local Iron Age horizons (Poznań, Płońsk, Końskie, Lusatian-associated layers) — suggests a mosaic of related communities rather than a single homogeneous polity. Radiocarbon dates across the sample set (6814 BCE to 1287 CE) indicate long-term human presence with episodic demographic change.

Limited evidence suggests some population turnover during late Bronze–Iron Age transitions, but the archaeological record also shows strong local retention of craft traditions. In cinematic terms: peat-smoke and river mist conceal centuries of continuity and contact, where local groups adapted incoming influences into familiar lifeways. Archaeological data indicates that these emergent identities would later feed into the ethnogenesis narratives of early medieval Poland, although the archaeological picture remains complex and regionally varied.

With 126 genomes spanning 6814 BCE–1287 CE, the Pre_Slavic dataset provides a robust window into population dynamics of Greater Poland. Maternal haplogroups are dominated by H (30) and U (29), lineages commonly found across Europe and often associated with long-term regional continuity. Haplogroups T, J and K appear at lower frequencies, reflecting typical European maternal diversity.

The Y-chromosome picture is more surprising and indicates notable heterogeneity: counts include L (19), CTS (14), M (11), R (6) and PF (6). Haplogroups L and M are relatively rare in contemporary Europe and their presence here — supported by multiple samples — could reflect several possibilities: survival of deep, locally rare lineages from prehistoric periods; gene flow tied to long-distance mobility during the Bronze/Iron Age; or complexities in haplogroup nomenclature and assignment that merit careful phylogenetic scrutiny. Archaeogenetic data indicates that some male-line diversity in Greater Poland may be the product of sustained contact across Eurasian corridors rather than a single source expansion.

Genome-wide affinities (where examined) are consistent with a largely Central European genetic substrate, with signals of admixture at different times. Given the sample size (126), population-level trends are meaningful, but interpretation should remain cautious: uneven temporal sampling and site-specific contexts can bias perceived continuity or change. Further targeted sampling and higher-resolution Y-chromosome phylogenies will clarify the origins of the unexpected haplogroups.
