Keep in mind that Central Asia had a demographic shift with the Mongol invasions
I aware of the demographic shift following the Mongol Invasion, Kazakhs and Uzbeks are a mix of Turkic and Mongol tribes for instance. But unlike Kazakhs and Uzbeks, Turkmens have no Mongolian clan among them and they look neither Mongolian nor Iranian, they look Eurasian if you ask me:

They had a dark brown complexion, their beards were shaven and they were poor compared to the Oghuz. In fact, among the Oghuz, I have seen people who possess 10.000 horses and 100.000 head of sheep....."
