The logic of your point is irrefutable. As R1b haplotypes move away from
DYS390=24 then the options are limited to downwards to 23, 22, etc and
upwards to 25 26 etc. I have not looked at these yet, when i get time I will
do, but i don't own the data. It is there for anyone to check my figures and
pursue other ideas. Also, as we both know, analysis of extra markers will
eventually help. I am aware that some alleles for some R1b markers have
never been found in Iberia. Also DYS439=11 looks stronger in
Holland/Denmark, and I recall from the old Yhrd archive that YCA1ia and ib
=19-22 is more frequent in the Baltic areas.
Originally, I thought the Alpine-South German R1bs (at DYS390=24 being about
60% of the total) were simply an overlap/admixture of the NorthSea/Baltic
and Franco-Iberian groups, but then i did the "difference" calculations and
discovered they were far enough apart from both sub-populations to be from a
different "universe". Then I tracked the DYS390=24 down the Rhine, along the
Danube and across to the Ukraine to discover that 60% is the ratio in most
places. Iberia and The NorthSea/Baltic may influence the Rhineland, but
hardly Romania and the Ukraine. Conclusion: there is another variant to the
A further puzzle was that the 70% achieved by the Iberians for DYS390=24
appears unexpectedly and inconsistently in places like Greece, Macedonia,
Albania, and Southern Italy suggesting the Iberian R1bs may have sneaked
along the Mediterranean, while the Alpine/South Germans were doing the grunt
work climbing the hills and going against the flow, up the Danube.
It might also be informative to repeat the excercise with R1a, to see if
there is any discernable contact or overlap between the sub-haplogroups in
eastern Europe/Western asia If only we all had more time!
