Iron Age and Anglo-Saxon genomes from East England reveal British migration history [Nature Communications]
English DNA 'one-third' Anglo-Saxon [BBC News 19/1/2016]
Were one million or more Britons wiped out by the English in a Dark Ages holocaust?
The evidence has been gathered from three burial sites near Cambridge: Linton for the Late Iron /Early Romano-British period; Oakington for the Late Romano-British/Early Anglo-Saxon period; and Hinxton for the Middle Anglo-Saxon period.
The research contradicts linguistic evidence (and previous DNA research) that the Anglo-Saxons wiped out the indigenous Britons. Even in the east where the Anglo-Saxon influence could be expected to be at its strongest there is evidence of integration and intermarriage in the genetic record. Further west we would expect to see a much lower Anglo-Saxon contribution.
This suggests a band of immigrants emerging as a cultural, political and military élite and imposing themselves, their language and their way of life on the indigenous Britons. The result over several generations was a cultural and linguistic takeover with the Anglo-Saxons calling all the shots.
The burial sites reveal a genetically diverse but culturally integrated population.
So less of a holocaust , more of a shotgun wedding.
