Britain has a long history of invasions: over the past two millennia, various armies from the Romans to the Anglo-Saxons conquered the bulk of the British Isles. A new genetic analysis of the country has revealed which invading force had the greatest impact on its DNA.

Nature: The results throw new light on several aspects of the peopling of Britain. For instance the genetic contribution to southeastern England from Anglo-Saxon migrations is under half, suggesting significant pre-Roman but post-Mesolithic population movement from the European continent. The data also reveal that non-Saxon regions contain genetically differentiated subgroups rather than a general ‘Celtic’ population.
