Turkic/Mongolic has ancient West Eurasian CHG and Iran_N components

[Alpakut]

from the new Jeong et al. 2019 paper:

Turkic/Mongolic-speakers comprising the bottom-most cline have a distinct western Eurasian ancestry profile: they have a high proportion of a component most enriched in Mesolithic Caucasus hunter-gatherers (“CHG”)

and Neolithic Iranians (“Iran_N”) and frequently harbor another component enriched in present-day South Asians.

The cline follows a north-to-south migration. So, this is very ancient. Very ANE-time-like.
Your interpretations also welcome.

Since this is a study about Inner Eurasian populations, if the number of admixtures is broad enough, and it is not taking as reference later populations, such as Iran_N or BA Steppe, I think this may be simply a signal of a much higher ratio of ANE:CWE (Common West Eurasian) due to a combination of many highly drifted sources (Iran_N, CHG, West_Siberia_N, Paleo-Siberian/Proto-Amerindian, EHG, etc.) in comparison with other mostly or virtually entirely East Eurasian populations to their east and northeast, and also in comparison with the more West Eurasian populations, which will generally have a lot of ANF/EEF and WHG, too.

I don't see too much what to do with these informations: the concerned pops are since a long time in a carrefour of pops crossings and linguistic changes, with opposite directions of moves according to periods, and diverse assimilations over time; big lines to begin, and a complicated patchwork to finish...
