Ancient DNA studies reveal new origins for Germanic and Viking populations

Two studies published in the journal Nature, led by researchers from the Universities of Copenhagen, Leiden, and Gothenburg, have utilized ancient DNA to reshape the understanding of European linguistic and population history. By analyzing the genomes of over 4,500 ancient individuals, including 712 newly sequenced genomes, the international team reconstructed population movements through a combination of genetics, archaeology, and linguistics.

A primary finding identifies a previously unknown migration to Scandinavia approximately 4,000 years ago. Researchers suggest that groups from the Baltic region moved into Scandinavia at this time, potentially bringing early forms of Germanic languages. This discovery suggests that the linguistic roots of English, German, Dutch, and Scandinavian languages arrived in the region roughly 1,000 years later than previously theorized.

The research also uncovered unexpected connections regarding the Viking Age. Approximately 1,500 years ago, a migration from present-day northern Germany into Denmark and southern Sweden occurred. This movement coincided with the emergence of Old Norse, the language spoken by Vikings, and may explain the cultural and linguistic similarities between Viking and Anglo-Saxon traditions in Britain.
