Celts weren't ethnically cleansed

For those interested in the Celts and the Saxons there's a new piece of information to take into account but the way to interpret the genetic research is the moot point:

The argument is, that from AD 430 to 730, the Germanic conquerors of Britain formed an elite, with a servant underclass of native Britons. Inter-marriage was restricted, and the invaders and their genes flourished. "But it is just not necessary to assume an apartheid-like system," argues John Pattison of the University of South Australia in Adelaide. "The evidence is compatible with the idea of a much more integrated society."
...
He concludes that people with Germanic origins came to Britain well before and after the early Anglo-Saxon period, and this long period of immigration can explain a relatively strong Germanic genetic signal today. He adds that about 60% of the current British population still has some native Briton DNA, arguing against the idea, put forward by Mark Thomas at University College London and colleagues that Saxon invaders ethnically purged the country.

Expect to see both interpretations of this research appearing in comments and reflections on Celtic Christianity.
