An international research team has analysed more than 4,700 ancient human genomes to trace the prehistoric movements linked to the spread of Celtic and Germanic languages across Europe, according to nature.com [1]. The work, co-authored by population geneticist Hugh McColl from the University of Copenhagen and historical linguist Guus Kroonen from Leiden University, combined newly sequenced DNA from over 700 individuals with published genetic data from approximately 4,000 ancient humans. The findings identify specific population shifts that align with established linguistic and archaeological records [1].

## Genetic tracers and Scandinavian origins

The researchers identified a distinct ancestral group that migrated to Sweden roughly 4,000 years ago, likely originating from Baltic regions [1]. This genetic profile served as a reliable marker to monitor the subsequent dispersal of Germanic languages. Around 3,000 years ago, this ancestry was present across southern Scandinavia and northern Germany, corresponding with linguistic evidence of regional language contact. Approximately 1,000 years later, populations carrying these markers expanded into central, southern, and western Europe, including the British Isles [1]. The genetic signature was subsequently detected in Anglo-Saxon individuals who spoke the Germanic precursor to Old English, corresponding with the initial emergence of runic inscriptions approximately 2,000 years ago.

## Back-migration and Celtic distributions

The genetic data also revealed an unexpected migration from regions in present-day Germany back into Scandinavia [1]. This movement coincided with the emergence of Old Norse, the ancestor of modern North Germanic languages, and the rise of Viking influence across the territory. In several regions, the arrival of Germanic-speaking populations overlapped with territories where Celtic languages had previously predominated. Around 2,500 years ago, Celtic languages covered vast areas of western and central Europe, extending into present-day France, Spain, and Italy, while modern speakers remain concentrated primarily in northwestern Europe.
