We have Syunik regional files in G25 format

 We have Syunik regional files in G25 format.  Special thanks to Mher Ishkhanyan for providing the files and Robert Navoyan for his perseverance for pushing forward the process.

I updated the Davidski's standard model for our purposes. I added two new pops Central-Farmers and CHG. And removed the Kura-Araxes because it's a late and composite pop.

Syunik Armenians are close to other Armenians. Which is another evidence that modern Armenians are quite tightly connected to each other people. 

They have their own peculiarities which were partly predicted in my Gedmatch analysis. They have slightly more Steppe and less Levantine affinity than the average. This difference almost certainly is the distant echo of Iron Age situation, and do not represent any important recent event. 

Events that could have affected Syunik gene pool in post EIA historic times are the influences from Iran, which is well known.  You can notice higher Zagros. It is this high Zagros coupled with Steppe that makes Udi closer to Syunik Armenians and not the CHG. As one can easily note Udis have quite low CHG compared to Daghestani speaking Laks. Which once more confirms the fact that current Udi gene pool do not represent a genuine Daghestani ancestry. 

Finally I add the RISE397 sample from EIA Syunik just prior Urartian expansion. The main changes that occured in Urartian and later periods are the increase of Zagros and Anatolian ancestry in Syunik at the expense of Steppe. In most likelihood this change is due to mysterious Biainili people influence.
