Subject: Re: [DNA] The fate of R-L11 in Europe
Date: Sat, 20 Aug 2011 22:34:01 -0400
One point I would like to add is a slight modification of the datation by Marko Heinila. Here is a link to a part of his table : http://sd-4.archive-host.com/membres/images/90261920431217746/R1b.png .
It shows that R-P312 is now dated 4300 before present which is the beginning of bronze age in western Europe.
R-U106 is considered slightly older but it may not be significant .
Bell beakers oldest findings in Portugal have been dated 4900 before present, clearly before the onset of these 2 groups if the dating is correct. I'll take these date as correct. I understand that many people have serious doubt about the link of western "R1b" and Bell Beakers. I don't.
The problem with R-P312 origin in the upper Danubian area is that this position isn't really central to the next P312 expansion. Also the quick split in main subgroups like L21 , U152 and Z196 doesn't explain the many P312* found in Iberia and France .
I don't know if R-L51 and R-L11 reached Iberia but 23andME would know and I asked a while ago for maps. It's also too bad that we still don't have better sampling from France, Spain and Portugal. I wouldn't be surprised by a R-L51 weak signal in Portugal.
I mean : I believe that R-P312 is more recent than expected. Then I expect R-L51 to have been the arriving group and, for some reason, it wasn't detected yet. If people have data, please, speak up !
About the 2 R-L11 spot I would rather say that they both are associated with R-U106. Some early U106 went down the Danube river to Austria, for example, some others went down the Rhine river, to Holland. My view is that R-L11 ---ยป R-U106 was a continuum while R-P312 was a rupture, a clan made its way apart from the parent group.
