I was going to do some reanalysis of Botigue et al.’s data set, when this paper came out: A common genetic origin for early farmers from Mediterranean Cardial and Central European LBK cultures. This inference comes from a whole-genome sequence of an ancient DNA sample. Specifically a 7,400 year-old Cardial individual (CB13) from the environs of modern Barcelona. The paper is open access, so read the whole thing yourself, it’s short. But the results are clear above. This individual has affinities with modern Sardinians more than any other modern groups. Second, come the Basques.

From the paper:

This paper deserves it's own thread.

Another interesting entry -

CB13 shows the ancestral variant associated with the inability to digest milk during adulthood (Itan et al. 2009); sharing this trait with all Neolithic individuals analysed to date (Gamba et al. 2014; Lazaridis et al. 2014).

A lot of H..Both H3 and H4.

I added CB13 to: Pre-Historic West Eurasian Phenotype: 7/7 Neolithic Spanish have Brown eyes and 50%(5/10)) LBK farmers have Blue eyes. Alleles in rs1426654 and rs16891982 look the same among the two.

A lot of H..Both H3 and H4.

H4a1a is the main form of H4 today. H3 has already been found in Early Neolithic Spain, France, and Germany.

Unfortunately no Y could be confirmed.
CB13 shares the same exact mtDNA line as the Els Trocs (Y-R1b V88 related, mtDNA-K1a2a) sample.

Too bad no YDNA? If we have CS7675's genome couldn't we get at the YDNA if he's potentially male from morphology? Maybe I'm overlooking something basic...it's been a long week.

This is from page 5 of the PDF.

Unfortunately, information on the Y-chromosome could not be obtained due to the low genomic coverage of the male samples.

Take a look at the screenshot again, which I reattached below, which shows the coverage of the specimens. Only CB13 had 1x coverage and that is the specimen used for comparisons to other ancient specimens. Even coverage at 1x is pretty low but enough for the comparisons but the DNA they were able to extract was way too little to test the Y.

H4a1a is the main form of H4 today. H3 has already been found in Early Neolithic Spain, France, and Germany.

More evidence that H3 is a Neolithic farmer lineage that originated in Anatolia/Near East. Where is H4a1a most common today? Europe?
