Here is the article: http://dienekes.blogspot.com/2011/12/first-assessment-of-1000-genomes.html
First assessment of 1000 Genomes Iberian Spanish (IBS) sub-populations
As promised, I have taken the IBS sample from the latest available 1000 Genomes data and split it into sub-populations. There are at present 147 IBS individuals, and 108 of them have regional information about them:
The one population that stands out in this set is that of the Basque Country (Pais_Vasco_1KG) which appears, like the HGDP French_Basque population to differ from its neighbors in having near zero of the "Caucasus" component.
I first speculated that some of the IBS sample were of Basque origin during the summer, and it seems that this was indeed the case.
The paucity of the "Caucasus" component in Dodecad, HGDP, and now 1000 Genomes Basques, together with the paucity of the "Caucasus"/"Gedrosia" components in Finns compared to northern Balto-Slavs and Scandinavians respectively is very suggestive, since these are the two major non-Indo-European speaking populations of Europe. (*)
In my opinion, these comparisons add weight to the growing body of evidence that the PIE Urheimat is to be sought in the territory of West Asia, as a secondary movement, about 8,000 years, ago of the broader series of expansions that began from this area 12,000 years ago.
(*) Hungarians are also non-Indo-European, but they seem to have received their language in historical times through a process of elite dominance.
- Well, It's a good beggining to start creating subgroups as more samples come. The graphics use the K12a model as pointed above, which has been discussed in the appropriate thread: http://www.eupedia.com/forum/showthread.php?27126-K12a-admixture-calculator
