Very interesting Sam.
I would try to find and use a few more samples for Generations4, just to
be sure the results won't change ...

(I since have found a second Ashkenazi sample tested positive in that cluster with another origin.) The estimate to the common ancestor for each separate cluster is around 600 to 1000 years. Several members of one cluster appear to be Sephardim and family lore of one of its members concurs.

They used their discredited (by me and others) 0.0007 mutation rate to estimate the coalescence age at 10,000 years. Anatole Klyosov and I recomputed the age using their data and calculated an age of around 4500 years for that migration. Anatole has also stated that he believes that R1b reached Spain by that route.

There may have been mutations along the way and a few may have migrated back again from Nubia to Egypt to the Levant. I leave open the question of whether Tut was one of the R1b in Africa for future discussion. I believe that one day an L4 positive Jewish sample will appear whose values at 385a/b are 11-14 instead of 14-14. In conclusion, I believe that R1b-L4 was probably one of the original haplogroups in Judea more than three thousand years ago.
