So the Yamnaya ancestry was not EHG men and CHG/Iran_N women, but the opposite: CHG/Iran_N men and EHG women (at least that's what I understood).
I think it is a problem that EHG is directly connected to CHG, even if two admixtures happened at Pontic steppe.
EHG carried mtDNA C, Baikal burial type and Baikal type pottery. J was found in EHG. Hotu people carried EHG admixture and Baikal type pottery. That is why I always say that PIE seems to appear in the triangle zone of neolithic Baikal, Karelia and Hotu cave.
Ural south east culture had contacted Caspian sea south east from Mesolithic to eneolithic. With gene data, WSHG migrated to Caspian sea south east and IVC. As I posted several times, sky God concept on altai petroglyph spread to yamna, ancient greek, china bronze, Hindu and whole America continent. (Representing mongol empire is only one Adna Gengiskan has. Do we need more?)
yamna also:
Around 1,600bc, chariot army dominated whole Eurasia including ancient Europe. As I posted in below, altai and neolithic Baikal culture also spread together.

We don’t know how ancient people classified themselves and how they thought. Scholars say logically that yamna people migrated to altai for mining and animal husbandry. Moreover harsh weather made Scythian migrate. However, I learned from one greek member that ancient greek people left home when they became teens.
Scholars think that mound grave culture on pontic steppe originated from south Caucasus. However, new evidence was found 5 years ago. Altai and west Siberia is too huge, but sparsely populated, hence, we don’t know what are buried in there.
"]A burial mound accommodating the remains of nine individuals dated to the Stone Age has been unearthed in western Siberia. The discovery’s significance lies primarily in the fact that this kind of burial site was believed to have emerged later, in the Bronze Age, Russian media report.
The discovery was made by archaeologists and students from the Kemerovo State University. The head of the archaeology department at the university, Vladimir Bobrov, told Interfax that common opinion in archaeological circles is that these kinds of burial mound, called kurgans and associated mostly with the Scythians, appeared in the Bronze Age, “after the discovery of the alloy.” The mound in Vengerovsky region, however, has been dated to between the sixth or fifth millennium BCE, in the Neolithic. Earlier finds have suggested that Neolithic people buried their dead in individual graves or at most buried two people in the same grave, which was no more than a hole in the ground, Bobrov explained.
This mound, however, was completely different. For one thing, it resembles a house rather than a grave. For another, it contains the remains of no less than nine people: men, women, and children, plus a stone axe and a horn-tipped arrow. To make things even more fascinating, the researchers working at the site found that the people had not all been buried in the kurgan simultaneously. Some of the occupants were laid to rest there originally, but others were initially buried elsewhere and only later moved to the mound."
