Re:Lack of overlap (Score 1)

Hm, while it's possible that that "Italian" look is due to Roman conquest, I would expect it to be more likely due to later Normand conquest, which also came from a former Roman teritory... Anyway, I don't find that map even remotely accurate or representative for "nation mapping", since it takes way too few samples and even the choice of sampling points across Europe is poor. Germany has 2 X 500 samples taken, which might be OK-ish, but all the rest of Europe only has about 1000 samples together. For instance, Italy has much less and Portugal has only 16. I think this is more of a "proof of concept" paper than a serious "mapping of Europe's genepool" as it claims. It actually is very far from that IMO.
