Still haven't been able to find an answer to this anywhere, and Geno/FTDNA haven't been particularly helpful. In fact I'm still waiting for an answer of any kind from them.
The European reference populations in the "First Generation" of Geno 2.0 (Britain, Germany, etc) all reflected some degree of Mediterranean or Southwest Asian DNA. (This represented the genetic component of the Neolithic migration into Europe from peoples of the Near East, that most all modern Europeans share.)
The European reference populations of Geno 2.0+, however, completely lack any such admixtures. Gone. Poof. Abracadabra. Into thin air. This is the case in all of them: British, Irish, French, German, et al. With the occasional remotely conceivable exception of some "Southern Europe" or "Jewish Diaspora" admixtures, the actual Neolithic components are gone in every one. The Euro reference populations are now almost wholly "European", lacking the Neolithic admixture that is well known to be there. Why? Nat Geno has not explained this recalibration, and it's irking me.
The readjustment has not been minor, either, nor merely semantic. If you compare the respective populations in the two different tests (linked above), you'll see that even in cases of "Southern Europe" or "Jewish Diaspora" of Geno 2.0+, the actual percentage is FAR lower than the respective "Mediterranean" or "Southwest Asian" of Geno 2.0 First Gen.
Thoughts? This is bugging me because my Geno 2.0+ results show me as having 2% "Arabian" DNA (the rest is all purely European), but according to the new reference populations, this is exotic.
