I won’t be able to do that as I sit on the peer review board of a journal of Turkic linguistics out of Turkey. I also have a chapter coming out in a new book about Turkic linguistics. In the chapter, I mostly talk about language, but I did talk a lot about history and origins too.
It’s pretty clear the original Turks from Northern Kazakhstan/the Altai were probably not White people, though that is probably in dispute. The later homelands, around the Altai where China, Mongolia, Russia and Turkey all come together were probably much more Asiatic. If you look at the Siberian Turkic speakers like Siberian Tatars, the Altai, the Chulym, the Shor and the Khakas, those are probably a good bet for what the original Turkics looked like. A good way of describing these people is half-Asiatic (Mongolic) and half-Caucasian.
This group also was apparently the base for the Amerindian populations as well. The Amerindians are fully Asiatic. So the people who birthed the Asiatics later birthed the Turks. However, there was some Caucasoid mixing in between with groups such as the Caucasian Tocharians. Later, Iranic groups mixed heavily with Turkics in the Stans.
The Tuvans also look like a very early Turkic group, and they are very Asiatic (Mongolic). The real pure Turkics from the Turkic homeland appear to be at least 50% Asiatic. The only reason they look Whiter as the get further west is that the Turkic Muslims conquered many of these people in Islamic jihads. These conquered Caucasians were then converted to Islam in the usual manner.
