I'm not the statistician to critique the Myres study thoroughly. I
would appreciate your evaluation and commentary on any of these.

'A Predominantly Neolithic Origin for European Paternal Lineages' by
Balaresque et al - 2010.
'A major Y-chromosome haplogroup R1b Holocene era founder effect in
Central and Western Europe' by Myres et al - 2010.
'Strong intra- and inter-continental differentiation revealed by Y
chromosome SNPs M269, U106 and U152' by Cruciani et al. - 2010.
'A map of human genome variation from population-scale sequencing' by
the 1000 Genomes Project Consortium - 2010

Their is a consistent theme in this studies related to R-M269. I'll
quote 1000 Genomes, "A striking pattern indicative of a recent rapid
expansion specific to haplogroup R1b was observed, consistent with the
postulated Neolithic origin of this haplogroup in Europe."

Their use of the word "striking" is appropriate. Just by looking at
haplogroup projects it is pretty easy to see, even for the unwashed
masses like myself, that the Super Western Modal Haplotype is real and
that for R-P312, R-U106 and R-L11 in general.... it's all the same...
very little difference across 67 markers for these clade modals. R-L11
"all" seems to have a very high frequency across Western Europe and
I'm told low relative variance, so I think this is significant.

Regards, Mike
