Just so you know, that's not admixture. It's cluster analysis (K=4) of a set of populations.
Basically, the more clusters you use, the more different the populations will seem. The way it works is: for each cluster the model makes an equidistant center point from the others. Then, the populations proportions are made up by the distant to each cluster.
If you do one (K=2) with Europe, Finns will probably be separated into their own cluster and the rest will show different proportions of both. It shows that Finns are distant from most European populations, not that "they're purer" or something.

When I said romans I meant the nations that descended from the Western Roman Empire, you dunce.
And then again, we have the genetic profiles of Early Republican Romans (patricians and plebeians alike) and they are closest to Northern Italians, Southern Frenchmen and Iberians...
