Presence of European DNA in the Japanese confirms Europeoid origins of "N"

Also of interest is the detection of Caucasoid haplogroups I,J,G,R in some of the studied populations. In some cases these may represent recent admixture, but they may also represent older events, especially in the case of haplogroups J,G which are rare in most former European colonial powers.

Thus Japan is the last location in Asia where previously detected N clades are found to be accompanied by other European DNA.

So wherever we find N clades, we find also other Europeoid DNA.

In Europe N is absent only from Ireland, Switzerland and Portugal, AFAIK.

Well, N is a macro-haplogroup, comprising several clades, and i seriously doubt there aren't any N types in those countries, perhaps much less than in other regions but that would be (probably) due to Atlantic Modal Type R1b being overall dominant. (Switerzland an exception, of course, because of it's R1b/R1a and I types).

[Ross]

Sure, the N clades must be presented all over Europe, simply so far they were not detected on the western periphery of Europe...

[Gil]

Well, but R is a lineage descendent from N*, the only difference is that N* and it's clades is more ancestral than R. THe mutation for N* probably occured in the out-of-africa context while R emerged in the Caucasus area.

Do you think ther Ainu people is the one who carried the european clade N into far east?

[Ross]

No, the Ainu people are fully Asiatic genetically.

If Japanese N is TAT-C, then it was brough to Japan by Siberians who were at least part Eastern European Cro-Magnons. There were purely Europeoid types to the east from Lake Baikal in those times.

If it's earlier clades, it was brought by undifferentiated types, or rather people with ancestral DNA.

[Gil]

Personally I tend to discredit the idea that the Ainu are "Europid" or "Caucasid" or whatever, mainly because I think they have traits which [b]seem[/] Europoid (skin pigmentation, bone structure, eye shape, etc) but, in my honest opinion, they are convergent traits that appeared due to local adaptation to climate, sexual selection and food sources. Evolution, human wise, tend to work in the same way provided the conditions are the same (in detriment or in favour).

[Carnyx]

But what about their heavy pilosity? Adaptation to climate as well? Food? Nah. It's a caucasid trait.

Mixed Aïnu with a big beard that a Mongolid could not even grew without some Caucasid influence.
