Does anyone have information on any y dna haplogroup determination for La Brana 1 and La Brana 2 bones which were found in Spain and dated at 7000 years b.p.? Or maybe they were female with no ydna? 8000 years b.p. bones of males found in more northerly Europe had their reconstructed genome compared with the I Tree and found to represent a new (now probably extinct) branch of the tree just a ways ancestral to L161 Isles and L147 Dinaric branches of the I Tree. See “Tree and Map for haplogroup I”. Kenneth Nordtvedt Haplogroup I Clade Modalities and Trees at: http://knordtvedt.home.bresnan.net

The preprint is available at http://www.nature.com/nature/journal/vaop/ncurrent/full/nature12960.html - from the supplemental material, La Braña 1 appears to belong to haplogroup C6, though based on a single SNP, as he was ancestral for the other C6-equivalent SNPs. They didn't get a read on the SNP that defines C5 as well. So he could be C6, maybe C5, and maybe C(xC6).
