Posts by this guy have lots of new info on genetics. Do a search for his name and the keywords "nodes, nodal, migration" and you'll find much more.
Some basic points that come to light:
1. Genetics finds at least 2 major East-West migrations in Eurasia (in other words, from W Europe to E Asia), and 2 West-East migrations that are traceable. Western European genes (traceable to France) have been found in Koreans, e.g.
2. There is a genetic gradient of Eurasia/America that goes from Spain through East Asia over the Bering Straight to the southern tip of South America. This is one huge racial unit.
3. Within this unit, there are a few islands of racially isolated types. The one in Europe is Ireland: which has the highest incidence of Super B8 genes, which are a distinctly "Caucasian" genetic marker. Irish have the most of these, followed by Cornish and Swedes. This type developed in Ireland during the last ice age, then spread out to Northern and Eastern Europe via an early expansion and the Norse, giving the "Caucasian" cast to Europeans. Prior to this Nordic expansion, East Europeans outside Ireland looked a lot more "Asian" - due to selection and ancestry, not because of gene flow.
4. Europe does have some genetic contribution from Africa. There have been time periods when North Africa/Southern Europe were a geographical unit - and cultures naturally spread over this entire area (the megalithic culture of W Europe/N Africa come to mind - as well as "Atlanto-Med race").
Anyone interested in some recent, hard-core genetic data, should follow up on this link. Do a search as I specified above - there is much more info.
