Leyla-Tepe culture from the Iranian Plateau PRE-DATE Maykop culture. It has been said that Maykop folks came from Leyla Tepe.
Agdam District settlement (
https://en.wikipedia.org/wiki/Agdam_District ) of Leyla Tepe is dated from
4350 B.C until
4000 B.C
I'm not talking about Ur, Akkadians and other Semites who came from the Levant into the southern parts of the Mesopotamia, but I'm talking about the NATIVE people of the Iranian Plateau.
Leyle-Tepe civilization predate all of them. Maykop culture was born out of the Leyla Tepe kind of culture. There was a migration from the Iranian Plateu into the Maykop Horizon.
Leyla-Tepe metallurgy PREDATE Caucasian metallurgy:
"
The appearance of Leilatepe tradition’s carriers in the Caucasus marked the appearance of the first local Caucasian metallurgy. This is attributed to migrants from Uruk, arriving around 4500 BCE.
Leilatepe metalwork tradition was very sophisticated right from the beginning, and featured many bronze items. Yet later, the quality of metallurgy declined with the Kura–Araxes culture. "

"
The culture has also been linked to the north Ubaid period monuments, in particular, with the settlements in the Eastern Anatolia Region (Arslantepe, Coruchu-tepe, Tepechik, etc.).
It has been suggested that the Leyla-Tepe were the founders of the Maykop culture. An expedition to Syria by the Russian Academy of Sciences revealed the similarity of the Maykop and Leyla-Tepe artifacts with those found recently while excavating the ancient city of Tel Khazneh I, from the 4th millennium BC. "
Other sites belonging to the same culture in the Karabakh valley of Azerbaijan are Chinar-Tepe, Shomulu-Tepe, and Abdal-Aziz-Tepe. "

I know all this, and I agree with you that the Gedrosian admixture in Yamna probably came from Leyla Tepe or another culture in Azerbaijan, northwest Iran, Armenia or Kurdistan (such as Korucutepe, as suggested by
Philip Kohl).
I was the one who claimed for the first time (in 2009) that R1b-M269 people were cattle herders from that region who crossed the Caucasus and mixed with the R1a HG in the Steppe and that the resulting merger of the two groups became the Proto-Indo-Europeans.
I also mentioned in 2012 that
PIE language showed similarities with Hurrian, the ancient language of Mesopotamia, which points to a common origin of the two in the same region. I also proposed in 2013 that
the Proto-Indo-Europeans possibly originated from the Uruk expansion.
Have you not read anything I wrote about it on the forum for the last 7 years? You don't need to convince me that there was a migration across the Caucasus that brought that Gedrosia admixture. I was also the one who proposed that Gedrosia was linked with the diffusion R1b when Dodecad K12b was released in 2012 (can't find the original post, but I explained everything in detail when I made the
Gedrosia admixture map and you were the first to reply to me).
Are you trying to take credit for all my theories or did you just forget that I was the one who proposed all of them?
That doesn't change what I am trying to explain here, which is that bronze was only used for the first time on a regular basis deserving to be called 'Bronze Age' in Maykop, was used for military purpose by Maykop and Yamna people and their descendants, and that they were the only real invaders. You need a military elements and battles to be able to
invade territories. Neolithic farmers did not invade Europe. They just moved a few kilometres further per year, with hunter-gatherers living side by side. There is no evidence that Leyla Tepe or other South Caucasian people invaded the Steppe. They just migrated and blended with the locals. If you have any evidence to the contrary, I would be very interested to read about it.
You are also forgetting something when you claim that people from the Iranian plateau were the first metal-age invaders. Leyla Tepe was in Azerbaijan, and if they descend from Uruk, the original PIE would actually be Mesopotamian. Neither of them are from the Zagros or the Iranian plateau as you claim. Azerbaijan is mostly lowland located between the North and South Caucasus, and Leyla Tepe was in the lowland, not even in the mountainous area that abut the country. So it's a bit strange when you write that "Leyla-Tepe metallurgy PREDATE Caucasian metallurgy". Leyla Tepe
is Caucasian metallurgy, just like Maykop! Perhaps our argument is about mainly about geography and the definition of 'invasion'.
