A commenter in a previous post left a reference to an oral communication by Aleksander Khokhlov – shared in a Russian forum on genetics – , from the XIV Conference on Samaran Archaeology, 27-28th January 2018 (still publicized in the Samaran Archaeological Society).
NOTE. You may know Khokhlov as a palaeoanthropologist, part of the Samara Valley project, like David W. Anthony. See the project referenced here, or their recently published book.
Here is my translation of the reported summary (emphasis mine):

User Camulogène Rix at Anthrogenica posted an interesting excerpt of Reich’s new book in a thread on ancient DNA studies in the news (emphasis mine):
Ancient DNA available from this time in Anatolia shows no evidence of steppe ancestry similar to that in the Yamnaya (although the evidence here is circumstantial as no ancient DNA from the Hittites themselves has yet been published). This suggests to me that the most likely location of the population that first spoke an Indo-European language was south of the Caucasus Mountains, perhaps in present-day Iran or Armenia, because ancient DNA from people who

An interesting open genomic question is the origin and spread of Caucasus hunter-gatherer (CHG) ancestry in steppe populations during the Eneolithic.
My broad theory regarding the appearance of this ancestral component is based on:
Two recently published papers ivestigating the Don Region may shed some light on this issue:
