Subject: [DNA] A new Talysh-Gilaki Caspian Y DNA J1 cluster
Date: Thu, 21 Apr 2011 11:09:04 -0300


I have discovered a new Talysh-Gilaki J1 cluster in the Sorenson Molecular
Genealogy Foundation (SMGF) database. The new Talysh(Talesh, Gilan) cluster
forms a branch of a larger new cluster with the united J1b
Portuguese-Brazilian+Northern Iranian cluster as the other branch.



__ _J1b Portuguese-Brazilian and Northern
Iranian(Gilaki-Tehran-Shahroud)

Root_ __I

I___ Talysh-Gilaki



Talysh-Gilaki J1 cluster: 393=12, 390=22, 19=15, 385=13-18, 388=15,
458=18.2, YCA=19-22, 461=10

J1b Portuguese-Brazilian and Northern Iranian cluster 393=13, 390=22, 19=15,
385=12-19 or 12-20, 388=16, 458=18.2, YCA 21-22, 461=10



The J1b Portuguese-Brazilian/Northern Iranian cluster had a star-like
expansion in the last 2000 years in the Westernmost end of the ancient
world(Portugal and the Atlantic expansion). The new Talysh-Gilaki group is a
smaller cluster, more homogeneous in terms of the STR diversity with a
bottleneck in the last 1000 years, at least with the SMGF available samples.



Historical sources connected the South-Western Caspian Ancient Iranian
peoples with war like ethnic groups like the Cadusii, the
Dailamites(Deylamites) and the Alans. The Cadusian cavalry fought at
Gaugamela against Alexander. The historian Josephus wrote about the
expeditions and incursions of the Alans in Hyrcania and in the country of
the Medes long before the great migration to Western Europe. Whatever the
origin somehow they participated in the first Atlantic Sea Discoveries and
took part in the land expansion of the new South American frontiers of
Brazil, keeping the old traditions of movement of this specific J1 clade.
