A recent genetic study published in the journal Nature has found that before the arrival of the Norse and the Saxons, the Briton or ‘Celt’ populations in the British Isles did not belong to a single, homogenous ethnic group. Researchers have found slight genetic variances in non-Saxon populations which indicate that the Britons were not one people, but instead were comprised of many sub-groups. This find reinforces a proposed theory that Britons self-identified as ‘Celts’ more in the national sense rather than as an ethnic group; not unlike self-identifying as British today regardless of ethnicity.
While some have questioned the finds of the researchers, the genetic tests confirmed previously well understood genetic origins of the U.K. Among the finds, over one quarter of the population derives some genes from the conquests of the Vikings, making them one of the largest ethnic groups to have lent their genetic makeup to the modern Brits.
