DNA Analysis Suggests Scandinavia's First Farmers Eradicated Hunter-Gatherer Population

New DNA Evidence Challenges Historical Narratives

A recent study led by Lund University, published in Nature, presents DNA analysis from ancient skeletons and teeth found in Denmark. The findings suggest that the arrival of the first farmers in Scandinavia 5,900 years ago led to the rapid eradication of the indigenous hunter-gatherer population, a conclusion that diverges from previously held beliefs of a peaceful transition.

Two Major Population Shifts Identified

The research indicates two significant population turnovers in Denmark over the last 7,300 years. The first occurred when a distinct farmer population replaced the gatherers, hunters, and fishers. This displacement happened within a few generations, with violence and new pathogens from livestock cited as likely contributing factors to the hunter-gatherers' demise.

Second Turnover by Yamnaya Descendants

Approximately 4,850 years ago, a second major population change took place. People with genetic roots in the Yamnaya culture, a livestock-herding group from southern Russia, migrated to Scandinavia. These newcomers replaced the earlier farmer population, again potentially through violence and the introduction of new diseases. The genetic profile of these Yamnaya-descended people is dominant in modern-day Denmark, while the DNA of the first farmer population has largely disappeared.

Implications for Scandinavian Ancestry

The study highlights that the current genetic makeup of Denmark largely stems from this second wave of migration. While less DNA material is available from Sweden, existing evidence suggests a similar pattern of population replacement occurred there. This research provides new insights into the demographic history and ancestral origins of modern Scandinavians.
