`  :::: Aigest, how do you know these Oghuz tribes (or any other ``Turkic tribes``) were compact groups of Turkic speakers and not heterogenous, including people of various origins (also natives when settled in one region or another)? Speaking of ``Oghuz tribesmen, who continued to live and fight according to the customs of Central Asia steppe``, I vaguely remember one legend (I will try to find the source and the original text/translation) about the origins of a nomadic tribe: 7 men left their village, in the next 7 villages they recruited another 70 (or 77), and so on.   `
