A comprehensive study in Current Biology has mapped the genetic transition of Southern Scandinavia from hunting-gathering to farming. Analysis of 100 sets of human remains from the period between 4500 BCE and 3500 BCE reveals a near-total population replacement within just a few generations. Unlike the gradual mixing seen in Central Europe, the Pitted Ware Culture and Funnelbeaker Culture interaction in the north was genetically distinct and rapid.
The study suggests that the shift was likely driven by a combination of new agricultural technologies and a pathogen-driven decline of the local hunter-gatherers. This research provides a critical update to the paleogenomics of Northern Europe, suggesting that the arrival of farming was a disruptive biological event rather than a purely cultural diffusion.
