I wasn't paying attention when they published it. I'm posting a comment I made on the 'CLV cline' on YT:
Ridiculous
Some of the linguists, anthropologists and whatnot they cite have speculated that Maykop could have been NW Caucasian.
Even if Yamnaya and Sredny Stog were PIE a movement from the 'CLV cline' could have brought non-IE languages to Anatolia like unkown EHG related languages or NW Caucasian at least. The Mesopotamian component makes the possibility of Kalehoyuk etc speaking non-IE languages even higher.
The samples are within the HATTIAN speaking area.
From Wikipedia:
"According to Alexey Kassian, there are also possible lexical correspondences between Hattic and Yeniseian languages, as well as Burushaski language; for instance, "tongue" is alef in Hattic and alup in Kott, "moon" is kap in Hattic and qīp in Ket, "mountain" is ziš in Hattic and ćhiṣ in Burushaski (compare also with *čɨʔs – a Proto-Yeniseian word for "stone")."
And it is said the Hittites (Nesites) conquered Hattusa around 1650 BC.

I may add that I have said in the past that in Northern Anatolia there would have been people different from the famers.
For example the older inhabitants of Kumtepe were NOT (culturally at least) ANF/EEF like.
And Xenophon had described some populations like the Mossynoeci which had cultures that did not seem ANF derived.
