Now even for the groups relacted to the Cardial Culture in Iberia, G2a seems to be the dominant male lineage.

So after France and Central Europe, again G2a.

This proves that related people, to be clear related males, spread the Neolithic culture by patrilinear inheritance. A very significant find, especially if considering that it is highly unlikely that the males before that Neolithic expansions were so much dominated by G2a, and of course in later times this successful male lineages were again substituted by others - probably including the Indo-Europeans.

That facts explain the Sardinian situation:

Sardinians have both higher levels of I and G than other Western people in Europe, seem to be both physically and genetically more stable, unaltered from Neolithic times on.

This is what we would expect if since the Neolithic period little significant genetic influx took place and Sardinia seemed to have been a Cardial Culture settlement area in the crucial time frame:

The study quoted on Dienekes blog is very interesting, but one question remains obscure to me, because the author wrote:
Maternal haplogroups found are consistent with pre-Neolithic settlement
http://www.pnas.org/content/early/20...61108.abstract

Now the haplogroups determined are:
Mitochondrial HVS-I sequences were obtained for the seven individuals and can be classified into four different haplotypes (Table 2). All are still frequent in current European populations (Table S1), and three of them were also found in ancient Neolithic samples (Table S2). These haplotypes permitted the determination that the individuals ave01, ave02, and ave06 belonged to K1a, ave04 and ave05 to T2b, ave03 to H3, and ave07 to U5 haplogroups.

Now while U5 and H3 can easily interpreted as Mesolithic, how can the same be said, with such a certainty, about K1a and T2b, if those haplogroups being also found in the Near East and so far in no unmixed Mesolithics, as far as I know, especially not in the West.

Even if being present in Europe before, especially T, the expansion to the West could still be dated to the Neolithic period, so I really wonder about that comment of the author.

Because with the two unsure haplogroups, more than the half of the women could be actually Neolithic derived as well.

Even more so if K1a and T2b being also found in Treilles, and K1a2 in Corded Ware remains from Germany, T2b also in early Neolithic Syria, K, T and T2 in the LBK's from Germany.

Going after that, it seems to be more likely to me, that that mtDNA-variants came with the Neolithics, rather than being local in the West in particular. So why does the author hold up such an opinion? Any ideas?
