UK DNA

Basically unchanged by most invasions. A priori that is weird to me. What did the other invaders get - material resources to exploit? (I also love the FAQ: "Are some regions of Britain inbred? No." NB, I live in Norfolk.) Here is the original paper, which has more amazing data and pictures: there are more distinct genetic clusters in the Isle of Orkney than in all of the South-East and central England combined.

There's also a unique Welsh borders cluster :-)

Update: the Guardian gives its perspective.
