> Nature studies from the University of Copenhagen analyzing ancient DNA found a previously unknown migration into Scandinavia around 4,000 years ago and traced Celtic languages to a Bronze Age spread from central Europe.

Two companion studies published in *Nature* on 4 November 2026 used ancient DNA to trace how Germanic and Celtic languages spread across Europe, identifying a previously undetected Bronze Age migration into Scandinavia and tying the Celtic language family to a corridor of expansion out of central Europe. The work was led by researchers at the University of Copenhagen's Globe Institute, working with colleagues at Leiden University and the University of Gothenburg, according to a press release issued through EurekAlert! on the same date.

The two papers draw on a shared dataset: DNA from more than 4,500 ancient individuals across Europe, including 712 newly sequenced genomes, according to the University of Copenhagen announcement. The first paper, "Tracing the spread of Germanic languages using ancient genomics", reports that a previously undetected population entered Sweden from areas around the Baltic Sea around 4,000 years ago and became widespread across Scandinavia by roughly 3,500 years ago. The authors argue this group is a plausible vector for introducing the earliest form of Germanic, the common ancestor of English, German and the Scandinavian languages, roughly 800 years later than most historical linguists had assumed.

"For over a century, scholars have debated when and from where the Germanic languages arrived in Northern Europe," said Hugh McColl, assistant professor at the Globe Institute and lead author of the Germanic-language paper, in the University of Copenhagen statement. "We discovered a previously unknown migration that occurred at exactly the time and place where we would expect the earliest form of Germanic to be spreading."

## A second, later migration toward the Anglo-Saxons

The Germanic-language paper also describes a second, more recent movement: around 1,500 years ago, people from northern Germany moved into Denmark and southern Sweden, particularly the island of Zealand, according to the press release. McColl said this population was closely related to groups that migrated to England during the Anglo-Saxon period. "This migration came as a real surprise," he said. "Archaeologists and linguists had not predicted it, but it helps explain several cultural and linguistic connections between Scandinavia and Britain that have puzzled researchers for a long time."

## A separate, century-old debate on Celtic origins

The companion paper, "Tracing the spread of Celtic languages using ancient genomics", addresses a different and long-running question: where the Celtic languages, now spoken in Ireland, Scotland, Wales and Brittany, originally came from. The study reports that ancestry associated with the Urnfield archaeological culture, and specifically its Knovíz subgroup in the Carpathian Basin, formed between roughly 4,000 and 3,200 years before present, then expanded across much of western Europe, including France and Britain, between about 3,200 and 2,800 years before present, before reaching the Iberian Peninsula by around 2,500 years before present. The authors say this supports a model in which Celtic spread from an eastern-central European centre through successive expansions of the Urnfield and Hallstatt cultures, rather than from a western European origin.

"The question of where Celtic languages came from has been debated for more than 100 years," said Guus Kroonen, associate professor of comparative linguistics at Leiden University and the University of Copenhagen, in the statement. "Ancient DNA gives us an entirely new way to evaluate competing theories and brings important new evidence into the discussion."

## What ancient DNA can and cannot show

Both papers are explicit that genetic data cannot identify what language a given population spoke. "DNA sequences do not tell us directly which language people spoke," said Eske Willerslev, professor at the Globe Institute and senior author on both studies, in the University of Copenhagen release. "But by combining ancient DNA with linguistic and archaeological evidence, we can begin to trace how languages spread and changed over thousands of years." The method pairs genome-wide ancient DNA with place names, loanwords and sound-change patterns drawn from historical linguistics, and with radiocarbon-dated archaeological sequences, which is what lets the papers propose specific population movements as candidate vehicles for specific language shifts rather than simply mapping genetic ancestry on its own.

For students and researchers in genomics, archaeology and historical linguistics, the two papers offer a concrete test case for combining ancient-DNA datasets of this scale, 712 new genomes added to a reference panel of thousands, with questions that have traditionally been argued from texts and artefacts alone. Kristian Kristiansen, professor of archaeology at the University of Gothenburg and a co-author on both papers, put it directly in the same release: "These studies show what becomes possible when genetics, archaeology and linguistics are brought together. Questions that have remained unresolved for generations can now be addressed with a level of evidence that was previously impossible."
