Biologists have created a map showing the genetic relationship of the average European country citizen to one another. The neat map shows how migration has morphed the blood of Europeans. (Hat tip: The Map Room)
Observations from the map:
Finland is something else. These people have a non-Indo European language that ties in with Hungarian, Estonian, and so native languages in the vast northern nothingness of Russia.
Italy never has had one ethnic Italian people. Rather, it is a collection of peoples under one nationality (even that is stretching it). Northern Italians have Germanic traits and have been in the sphere of Germanic people. Meanwhile the South has had everything from Greek Romans to Arabs to Albanians intermixing.
United Kingdom has overlap from Norway and other places where R1a genetic line is concentrated. Perhaps this is how the proto-Catholicgauzes came to Great Britain.
