Actually there is no "verbal debate" embedded anywhere in my post. Plain and simply I have just read Manni's most recent article (and he references similar studies in France with similar results) and I have concerns especially about assumptions in relation to studies comparing English haplotypes to those of Friesland. Would you not agree that this is a very poor choice or regions upon which to base a comparison?
I was also thinking that while we wrestle about the Central European situation, perhaps, at least for me, the focus should be on SNPs (yes, of course I do have a vested interest in this matter). Ok, I will develop a comprehensive "I package" to assist (I spoke to those who might have a commercial interest in the same thing and they were ok with this - what the heck, competition is good anyway). In terms of R1b I am fascinated with the possibility that some of the SNPs seen so far in Iberian studies may also show up in Ireland (if some of the hypotheses I have heard on the List lately hold water) - or for that matter elsewhere in Europe thus lighting the way for understanding migration paths.
Anyway, it makes excellent sense for us SNP chasers to forge ahead full speed; and you haplotype explorers do the same - then compare notes. A robust understanding of the DNA tapestry of for example Europe is going to come from an investigation in both arenas.
