If we assume that most of genome is from Iranian and Anatolian Neolithic, we still see them as exact mix of both, and Armenians located exactly halfway between them. We also see substantial pull towards EHG and the Steppe. In contract Chalcolithic Iranians don't have Steppe influence, and exactly composed of two Neolithics.
"In the area" was very used very liberal, and axamples were various non-IE languages. I'm not saying anywhere that they are related to each other or originated in Anatolia. Take it easy dude.
Right, let's discredit people who do extra stuff, instead of recognizing their efforts.
Or if it is r1b they find they become less dubious, but when it is r2 their dubiousity shoots the stars?
. Anyways obvisouly big blue eyes are going to be a noticeable novelty in Asia and a unique attractive trait, just as brown skin would be in Europe. I don't think we should always assume fair pigmentation is somehow special and favoured and has an evolutionary advantage. If it did then many more would have it in Asia. Selection can be neutral and go in both directions. In Sardinia for example less than 5% have blue eyes while in Neolithic Central Europe at least 1/3 did.
Alan;482392]The EHG admixture in Copper Age Iran equals that found in mesolithic CHG.
Well, not if we go by this chart, but the level of EHG in Armenia Copper Age is pretty close to that in CHG.*
Well, it decreases in the Early Bronze Age, but it increases to the highest levels in the Middle/Late Bronze Age, so by then, whatever was the case in previous eras, there might have been movement from north of the Caucasus.
I agree that it's complicated, and I don't see this as a simple matter of steppe intrusion. Part of the difficulty in interpreting what we see is that we don't have an Armenian Neolithic sample. The other problem, as Lazaridis pointed out in his post, is that we don't know the geographical range of these ancient people.
Let's assume, for the moment, that CHG resulted from the admixture of a population similar to the Iranian Neolithic who moved slightly north and encountered EHG. Did they encounter EHG already south of the Caucasus? Or were the EHC only north of the Caucasus, but the resulting admixed population straddled the entire Caucasus range. These are things we don't yet know and may perhaps never know.
That's why I don't know whether there's a hard and fast case to be made that the Armenian Copper and Early Bronze Age results necessarily imply a move from the steppes, although there is the R1b result to consider.
By the Armenian Chalcolithic we actually see, as you say and as I pointed out upthread, that EHG has decreased at the expense of an intrusion of Levant Neolithic and WHG. Is that actually just a breakdown of the Anatolian Neolithic that arrived from the west? Does that make more sense than a migration of purely Levant Neolithic people all the way north?
Then in the Armenia Early Bronze the EHG declines yet again, perhaps by admixture by a population heavier in Iranian Neolithic?
Only in the Armenia Late Bronze Age do we see the EHG levels rise back to the levels of the Iran Chalcolithic. That's the strongest case for steppe intrusion, in my opinion.
This is the confounding factor that might change all of this.

Yes and when they moved North and especially later when the adopted a Vitamin D poor Neolithic_Diet, the became fairer. They combination of Genes+enviroment+diet is the key.
they were freakn too "dark pigmented" for the lattitude they were living at. Their pigmentation and light eyes level was comparable to that found on the Iranian_Plateau and Anatolia today. But after they established themselves on the Steppes they went through a drastic shift towards light pigmentation.
