This study goes back to 2015, the “People of the British Isles Study”: S. Leslie (et al.), “The Fine-Scale Genetic Structure of the British Population,” Nature, vol. 519, 2015, carried out by University College London, and the Murdoch Children’ Research Institute. The study found that the British people are still basically living in the same tribes that they were in the 7th century. Prior to the mass migrations of the 20th century, there were distinct groups of genetically similar individuals, geographically close together.
DNA samples were taken from over 2,039 UK people, and compared to the DNA of over 6,000 present day Europeans. It was found that genetically similar individuals were still inhabiting the same regions that their ancestors inhabited at the time of the Anglo-Saxon invasions, indicating a remarkable genetic stability over the last 1,400 years. People in central and southern England had a significant DNA contribution from the Anglo-Saxons, but because of the genetic similarities between Anglo-Saxons and Vikings, it was not possible to separate the Viking genetic contribution.
