"Europe has been colonized three times in the distant past, always from the south. // The pattern of genetic differences among present day Europeans probably reflects the impact of these three ancient migrations, // The map also identifies the existence of two genetic barriers within Europe. One is between the Finns (light blue, upper right) and other Europeans. It arose because the Finnish population was at one time very small and then expanded, bearing the atypical genetics of its few founders. The other is between Italians (yellow, bottom center) and the rest. This may reflect the role of the Alps in impeding free flow of people between Italy and the rest of Europe."
