I read this too, has something to do with the immunity to the black death.
I read somewhere that there was a scottish village where all but two inhabitants died because of the black death virus. Just now they found by looking at the dna that they had a gen that gave them their immunity.
The same thing happened on a larger scale in the whole of Europe, all the immune people survived, making their relative presence much bigger.This is btw also an example of evolution where a preceived flaw in someones DNA structure turns out to be having a positive effect and causes the species to evolve.
