Um, just to add tidbits for those fascinated by genetic heritage:

Finnic peoples appear to have evolved around the Obskaya Gulf region (northern Russia near the arctic circle) as all of us seem to have evolved near waterways.

It appears that they were invaded by (enslaved by, fought with) asiatic siberians in recent prehistory.

We don’t think of it today, but the ‘eskimos’ (Inuit/Siberian/Arctic peoples) around the arctic circle were aggressive warriors and were successful at exterminating multiple tribal groups – including most of their predecessors in the new world.

North Russians (Muscovites) are about 25% finnish composition. (If you are still one of those people that think ‘breeds of humans’ are indifferent science has arleady falsified the blank slate, and is in the process of falsifying tribe, subrace, and racial similarities – and we are pretty sure we know the sources of those differences.)

Every gene study I have seen suggest that the mongol invasion had very little impact on the slavic peoples. Conversely, the slavic slave trade had a significant genetic impact on the Byzantine/Turkic population.

The region’s major gene exporter was today’s Poland, and Poles, Ukrainians, and southern Russians (who are, contrary to russian ‘historicism’, ethnic and previously linguistic ukrainians) spread throughout the territory. They do not have this Finnic and Siberian admixture.

Russia found eastern european and baltic countries too difficult to rule becasue they were more developed than ethnic russians. So the soviets moved rural russians who had been serfs (slaves) only one or two generations before, into eastern europe and the baltics as the work force.

The asiatic population of siberia is trivial. Ethnic russians dominate the population everywhere except tribal areas just as canadians host tribal communities in the north.

So we do see a bit of asiatic gene expression because of (a) russian relocation programs, (b) mongol invasion, (c) the usual territorial cross breeding, and (d) the mobility created by sail, rail, road, and the russian and soviet empires.
