Which undermines your earlier remark on Ahmarian influences in Gravettian.
It's not my 'remark'. Broad similarities in Upper Paleolithic sites can exists alongside distinct cultural trends. You're reducing the whole study of early prehistory to absurdity.
Both the origin of mtDNA U6 and the resurgeance of GoyetQ116 in Magdalenian point to something more complex that that sink. It may need to be reconsidered.
A single sample isn't sufficient to establish the origin of mtDNA U6. Structure within early European populations doesn't mean that Europe was not a sink.
True, although comparison of a 14k yo old sample with present day North Africans is not very meaningful.
It is.
That article itself also claims that Villabruna lies nicely inbetween Early Upper Paleolithics and Late Upper Paleolithics.
That's because Early Upper Paleolithic humans retained tropically adapted skeletal morphologies much like Austrlians or equatorial West Africans.
If you take a look at the PCA's it isn't all that dramatic and may very well be on the tail of normal variation.
Possible.
Well, it was established with Loschbour so you'd have to figure out a way of admixture before the bottle neck but after LGM. LGM being the best, even only good candidate for the bottle neck as we know population of humans dropped and stayed low during it.
Again, there were no barriers to gene flow in the North Mediterranean. Human populations dwindled due to mass extinction resulting from drastic climate change, not the cold per se.
It simply doesn't fit IMHO.
I'm assuming you simply don't like the idea of Near Eastern gene flow.
