Analysis of this genome in the context of other ancient samples suggests the existence of a common ancient genomic signature across western and central Eurasia from the Upper Paleolithic to the Mesolithic. The La Braņa individual carries ancestral alleles in several skin pigmentation genes, suggesting that the light skin of modern Europeans was not yet ubiquitous in Mesolithic times. Moreover, we provide evidence that a significant number of derived, putatively adaptive variants associated with pathogen resistance in modern Europeans were already present in this hunter-gatherer.

Blue-eyed and dark skinned like Lochsbour. Very unlike modern South Euros genetically, and also "Eastern-Shifted" on the level of East Finns and North Russians in the global PCA. Does not cluster clearly with any single European population in only European-wide PCA

So by now we can say Mesolithic people looked like light eyed wogs.

C6 Y-DNA is extremely surprising.

They apparently got that far in just one of their analyses, and mention it's possible that it just looks like C6 because of DNA damage. It is still the most likely possibility.

Other "less likely" haplogroup affiliations mentioned are C* and C5, but based on current C distribution I'd also say it's C6.

In general, individuals from Oceania, East Asia, and Americas exhibit a genetic affinity to the Mal’ta sample, whereas individuals from the Middle East and Europe show a genetic affinity to the La Braņa 1 sample. Further, though the comparison between Sardinians and the Mal’ta samples suggests that the Mal’ta individual is closer to the La Braņa 1 sample than it is to any of the other modern European populations.
...
We wished to test whether the Mal’ta individual is closer to the La Braņa 1 individual than it is to modern Europeans. To test this, we chose the outgroup as the modern Yoruban population, H3 as the Mal’ta individual, H2 as the La Braņa 1 individual, and H1 as a modern European population from the HGDP. Table S10 presents result for this analysis, indicating that the Mal’ta individual is closer to the La Braņa 1 individual than it is to any European population, with the exception of Orcadian and Russian populations.

This result from an ancient Spanish C-V20 guy is interesting, and does not seem to bode well for Davidski/Polako's idea of later R1 Indo-European expansions being the main source of so-called ANE admixture around continental Europe.

Edit.
La Braņa also shifts slightly towards Han compared to most HGDP Europeans (the uppermost European samples, what looks to be Adygei and North Russians shift also, and La Braņa remains between them).

Visible when comparing graphs a (Karitiana affinity) and b (Han affinity). Maybe La B had some "ENA" too?:fponder:

I made a thread about this too.
http://www.theapricity.com/forum/showthread.php?112037-La-Brana-1-had-blue-eyes-dark-skin-and-Y-DNA-C-V20

I doubt he had and Loschbour had dark skin. The reason is these three light skin mutations are about as popular in near easterns as they are in Europeans also they are almost completely non existent in southern Arabians who have basically the same skin color as near easterns like Assyrians. There are other sources to European light skin. Today Mesolithic European ancestry correlates with light skin, light hair, and light eyes. Why are northern Europeans(the most Mesolithic descended) the lighter skinned than southern Europeans and near easterns and why are southern Europeans lighter skinned than near easterns. The reason I think is that there are factors to European light skin that Mesolithic Europeans have and north Europeans have the most of. So in my opinion La Brana-1 and Loschbour both probably had light skin. I am of course still considering they had dark skin, but I think many are assuming they did.

So could be as Dienekes wrote on haplogroup C being a pan-Eurasian haploroup?

Eupedia also goes along similar lines imo
