Some turkish who are claiming that these Yoruks are pure Turks or Seljuks tribes is contradicting to the Turkmen looks from Central Asia and middle east. The problem is way too many of them have way lighter skin, light eyes and light hair and even the darker one still don't look like those from Turkmenistan or Iran. These Turks look whiter than Turkish people. I'm not even talking about the ones that look Mongoloid but even in terms of Caucasoid there is huge physical difference. There's no way that these are the Turk invader in pure form, their origins must have been Indo-European anatolian tribes.
NOW LOOK AT TURKMEN FROM MIDDLE EAST AND TURKMENISTAN
Turkmen and Iranian-Turkmen don't look anything like these
