"Europid" is the same thing as Caucasoid. Its actually a bad term since it does make people think of a subclassification of European Caucasoids.

[Motörhead Remember Me]

The speakers in Siberia belong to the general physical category Mongoloid, while the speakers in Turkey belong to the general physical category Caucasian. There is huge genetic variability within the Turkic language family so there is not a specific type of Turkic person.

That being said, in ancient times there was an original Turkic group that arose out of a specific location and expanded.

But also keep in mind that that proto-Turkic language was a subset of the greater Altaic language family.

The eastern Siberian speakers of Turkic languages are quite recent newcomers to the area, and they got there from the "Turkic homeland" between modern day western China and Uzbekistan.
