Yeah, I've heard of the Huns. Now, have you heard of the Ice Age?

East Asian migration to Europe made a full 5% impact on ALL European populations. With small populations, the migration of a few mighty hunters, or the importation of a beautiful woman could have a massive impact.

The Huns added a very negligible amount ~ same for the Mongols, etc.

The B blood type, the most common in China for example, is more prevalent in Poland than Germany, France, or Britain and much more prevalent in Hungary than any of those suggesting stronger Asian ties. Look also, for example, at the distributions of haplogroup C3 as well as N, P, and Q.

And while it's true that a small migration can leave a larger genetic footprint on a small population, a relatively small group of military conquerers can leave a fairly large genetic footprint. A team of geneticists claim that 1 in 12 men in Asia carry a Y chromosome mutation that originated in Mongolia 1,000 years ago, the legacy of Genghis Khan's conquests.
