Just published in AJHG. Abstract here:

The full file can be seen at the link in my previous email. There is an
excellent map of Ireland showing haplotype density.

My summary of their article: What we have been calling the "Irish" variety
of R1b on this list is called the Irish Modal Haplotype (IMH) by the
authors. They associate the pattern with the Ui Neill (Descendants of
Niall), semi-historical and semi-legendary kings of Ireland beginning some
1500 years ago. The significant presence of the IMH in Ireland, Scotland and
areas around the world settled from those lands is attributed to the
"Genghis Khan" effect, in which members and descendants of a ruling family
outbreed contemporaries to leave a significant mark on the genetic
landscape.

This would mean that 25/11/14 R1b is quite a bit younger than I had been
thinking. In previous posts I had expressed the opinion that it would have
begun to diverge from mainstream R1b some three to five thousand years ago.

There is much here to think about.
