Repeating one paragraph from another message:
"Finally, I went to the Faux website and copied the four L2- , DYS492 =14 persons with 67 markers to Generations4 I repeated the interclade age calculation to one L4 person and got ages that ranged from 106 to 147 generations with SigmaG ranging from 35 to 43.
Whether the distance between L2- and L4+ is 100 generations or 200 generations is not important for my original purpose. L4 clearly predates the Diaspora!"
We await more data on L4.
You originally asked for my opinion which I gave along with some supporting evidence. Others intervened with commentary and I have now responded to them. Remember a few years ago, some claimed that my own R1b1-P25* was from European ingression. One "expert" speculated on the Netherlands as the source. I believe that that belief has now been superceded by a general recognition of a Middle Eastern origin. As an aside, I have even found four new members of my cluster in the last week with one from Gwent, South Wales.
