Subject: [DNA] J1b M365 Calculation of Time to Most Recent Common Ancestry(TMRCA)
Date: Sat, 6 Mar 2010 19:07:42 -0300


J1b M365 has a very rare Y STR motif. 393=13 390=22, 19=15, 388=16,
458=458,2 YCAIIa =21, YCAIIb = 22. I have found two geographically well
defined J1b clusters. There’s the Western Iberian, basically a Portuguese
cluster, Old Christian (Cristão Velho), Catholic, J1b cluster found in
Portugal, Minho, Azores, Portuguese borders (Galiza, Extremadura) with a
regular expansion and presence in Brazil. In the FTDNA J Y DNA Project the
Western Iberian cluster is easily recognizable. The other discovered
cluster has been the Northern Iranian cluster.



In 2009 Professor Klyosov kindly calculated the TMRCA

001_Portugal 13 22 15 11 12 20 11 16 11 13 11 30
005_Brazil 13 22 16 10 12 19 11 16 11 13 11 29
007_Belgium 13 22 15 10 11 17 11 15 12 13 11 29
009_Azores 13 22 15 10 12 19 11 16 11 13 11 29
010_Spain 13 22 15 10 12 19 11 16 11 13 11 29
012_Brazil 13 22 15 10 12 19 11 16 11 13 11 29
013_Ferrere 13 22 15 10 12 19 11 16 11 13 11 30

The J1b cluster of 7 haplotypes should give the following time span to the
common ancestor: 1725+/-570 years.



Now I have more markers from the SMGF (Sorenson Molecular Genealogy
Foundation). The Iranian haplotypes are concentrated in the Northern Caspian
area, Gilaki, Rasht, Astane, Talesh, Rezvanshar, Mazandarani, Tehran, Fars

The Northern Iranian and the Western Iberian clusters are forming a perfect
continuum of haplotypes. The Iranian cluster is the older and the most
diverse cluster but there’s no distinct DYS maker in the SMGF 37 makers
specific to differentiate any of the two distant geographical clusters. I
keep the idea that a unique cluster can correspond to a unique historical
event linking directly an Iranian speaking population to Western Iberia, the
hypothesis of the Alan migration and invasion of Lusitania in 409 AD.
