Yet this is the behavior she metes out to her present hosts.
This is the kind of thing we can get hard statistics on these days through genome analysis, and the weight of evidence suggests that Britain’s population in 1950 was very heavily descended from its population in 1100.
But I think Steve underplayed his hand. H/T reader TS for drawing our attention to British Have Changed Little Since Ice Age, Gene Study Says National Geographic News James Owen July 19, 2005

When reading this I was somewhat surprised how relatively limited the Saxon and Viking contribution was.
"There's been a lot of arguing over the last ten years, but it's now more or less agreed that about 80 percent of Britons' genes come from hunter-gatherers who came in immediately after the Ice Age," Miles said.
