very few details :

“As a result, it was found that the genes of our distant ancestors correspond with those of modern Armenians,” he continued.

who knows more about this?

Awesome Find. But we've heard Armenian geneticists say the same thing about other ancient DNA results from Armenia even though the truth isn't so simple. It just means they belong to the same South Caucasus/West Asian genetic cluster modern Armenians do.

A 7,000 year old person similar to modern people in the South Caucasus proves EEF and CHG had begun mixing there really early on. That's the same time frame as LBK and Cardiel cultures in Europe.

Armenian and Georgian genome is 70-80 percent made of Caucasian and Baloch admixtures. These admixtures where always there in the area. The rest is EEF, Iranian Farmer and Levant/SW Asian. However BA Armenian samples are very different and don't exist anymore.

Which is really weird, it seems those with BA Armenian admixture have left but the people still speak an IE language, maybe proto-Armenians descend from a different population with an already diluted steppe admixture?

Urartu was a multi-ethnic multi-linguistic empire. (just like the Hititte empire)
Their original official language was Hurrite.
Then there was a dynastic switch and the official language became proto-Armenian.

We have to ask the question: why would a dynastic change cause a change in language? if rule merely shifted from one Urartian family to another shouldn't the language remain Urartian? I don't think it is a coincidence that Armenian was established as an elite language by a dynasty with an Iranian (https://en.wiktionary.org/wiki/%D4%B5%D6%80%D5%B8%D6%82%D5%A1%D5%B6%D5%A4#Old_Arm enian) name (https://en.wiktionary.org/wiki/%D4%B5%D6%80%D5%B8%D6%82%D5%A1%D5%B6%D5%A4#Old_Arm enian), in my humble opinion, that might mean that the proto-Armenians were part of a coalition of Iranian tribes (they weren't descended from Iranians, but rather allied to them) united by Cyaxares of Media (https://en.wikipedia.org/wiki/Cyaxares), Armenian itself is a heavily Iranianized language with almost half of its lexicon being of Iranian origin, if we were to connect that with the dilution of steppe admixture, we reach the conclusion that proto-Armenians may have arrived from the southeast of Armenia proper?

Seems clear that r1b-z2103 from lake urmia is the remanent of a yamnayan penetration. So if there is yamnayan in azerbaidjan there is yamnayan in anatolia...

I see there is a shift from Caucasian to NE Europe and some Baloch.
Would you think Armenian R1b-Z2103 came to Armenia through Iran, south of the Caspian?
What about the supposed link between Armenian and Greek, which was allready in Greece with Mycenians?

You see what you want to see. There are samples with high NE Euro already in the Chalcolithic, especially I1409 (25.53% )
while in LBA there is a sample with 59.95% Caucasian (RISE412).

while in LBA there is a sample with 59.95% Caucasian (RISE412). I think the Steppe penetration into Armenia was initiated in Chalcolithic around 4k BC. That would explain first and oldest split of Greek/Armenian and perhaps Tarim Basin guys from the rest of IEs. The rise412 can represent indigenous population who didn't mix with IEs, and is very close to modern Armenians.

There is pretty good continuity of modern Armenians since CHG.

I think the Steppe penetration into Armenia was initiated in Chalcolithic around 4k BC. That would explain first and oldest split of Greek/Armenian and perhaps Tarim Basin guys from the rest of IEs. The rise412 can represent indigenous population who didn't mix with IEs, and is very close to modern Armenians.



it makes sense to me
that would be the time of expansion of R1a Srubnaya/Sintashta and the expulsion of R1b Yamna out of the steppe

Gedrosian admixture is linked with J2a from iran, a second bronze age wave from anatolia throught balkans even push them into british islands. Thats why people are so much confused they dont know how to seperate multiple migrations. All this has nothing to do with R1b or even CHG that lebrok wrongly think is born here, althought we know that CHG is related with ANE.

Maybe you have some skills to read among hen guts, concerning J2a in Britain? Could you develop your reasoning about ANE, CHG and Gedrosia; Perhaps it could help me to understand.

I know, right? Indo Europeans were probably just a bunch of 5'4 drooling morons who picked their noses, had huge ape like jaws, spoke in grunts, beat their women, and the stupid chariot that everyone lauds was invented by the lone "gifted" indo European with an IQ of 97 who spent days thinking about how to build one.

There is absolutely no need for that kind of thing. None of our ancestors should be described in that way. Indeed, no group of humans should be described in that way. Cut it out or there will be consequences.

i don’t get it either. The fascination with Indo European’s.

When I first learned about the IE languages and their common origin, I was awed by how widespread the family was, how all these languages were originally one, it fascinates me to this very moment.

I know and it saddens me that such an interesting topic was hijacked by the Nazis and their modern leftovers, their fantasies were built on old disproven pseudoscience, and it should be viewed as such.

I think it's normal to be fascinated with a language family, whether alive or extinct, it tells a story, a story of the migration of peoples, it tells history. Another interest of mine is the Afro-Asiatic languages, combining linguistic and genetic evidence it seems likely that Afro-Asiatic originated in the Natufian culture and was spread to Africa by Levantine farmers, Ancient Egyptians, Cushites, Chads, Berbers, Semites and probably other extinct cultures were all descended from one linguistic community that lived in the early Neolithic villages of the ancient Levant, it is quite mythical really.

Indo-European society was probably divided into three classes of Priests, Warrior Nobles, and Commoners. When an IE speaking tribe would "collide" with another group, and somehow assimilate them, their social pyramids also "combine", meaning that not all the newcomers are going to be warriors and not all the indigenous are going to be commoners, remember that the Mycenaean noble didn't differ much from the commoners, and J2a was also found among them, and the major ancestral component was Anatolian Neolithic, which means they intermarried with the population before them.

They are an interesting group.
