It is convincing me that proto-Turks were chiefly East Asian like looking. Of course the situation could be more complex, some groups could be mixed enyough to have some European features.
2. One of six is not much, however they had East Asian admixture, but I thing it wasn't considerable one. That is because of such a low East Asian admixture in southeast Europe reaching 2,5% while in this area settled Huns, Avars, Bulgars, Khazars, Pechenegs, Cumans, and Tatars.
3. There is some hypothesis that Bulgar could be descendents of Iranic speaking tribe from Pamir.
Edit: Interesting thing about Crimean Tatars is that they resemble rather Persians then Turkmens, mongoloid features are rare among them, which might be connection to Iranic Khwarezmians.
1. Scholars and linguists place the Proto-Turkic urheimat in the Altay region which lays between Central Asia, Siberia and Eastern Asia. The Pazyryk culture in the Altai mountains is a hot candidate for Proto-Turks and the geneticist have tested the Pazyryk burials and it came out that were Eurasian (mix between Mongoloid and Caucasoid). The people of the Pazyryk culture had also the same culture as the people who live today in the Altay mountains, the Turkic Altaians. My theory is that the Pazyryk people were Eurasian Proto-Turks who mixed with Eastern Iranian nomads and Mongols. Turks and Azeris have still 7-15 % Mongoloid admixture on average and Chuvashs have even 20-25 % Mongoloid admixture on average. That's too significant to be only Western Eurasian at least for Chuvashs. Kazakhs and Kyrgyz have also 30 % Caucasoid admixture on average which makes them almost Eurasian genetically. Yakuts and Tuvans are predominantly Eastern Eurasian. Here are you right!
2. Five of six skeletons still showed a more Asian apperance than a European apperance and only 6 skeletons were tested. That's too little. It's normal that Eastern Europe has only 1-2 % Mongoloid admxiture on average because the Turkic steppe nomads who were anyhow not fully Mongoloid mixed only with Caucasoids when they settled there. If you as an East Asian person would only mix with Caucasoids and your children and their children also, then there is not much of Mongoloid admixture left for the future generation.
3. Crimean Tatars look nothing like Persians sorry. They are even more Mongoloid admixed than Volga Tatars. The etimology of the name Bulgar come from the Turkic verb bulga (to mix, shake). It is accepted by most scholars, historians and linguists that the Bulgars were a Turkic tribe who spoke the Turkic Bulgar language and that Chuvash language is the only surviving Bulgar language today.
