And the Proto-Indo-Europeans are not the Aryans - the Aryans were a much later daughter culture in Western Afghanistan, Northern Iran and India, and probably the folks that had the beliefs outlined in the first pages of the Rig Veda.
The steppe people I am referring to are the people of the Yamnaya culture and related peoples within their horizon. The Mongols and Turks were relative late comers to the western steppes.
('Aryan' is cognate with the proto-Indo-European 'h₂éyos')
As an aside, I recently discovered (from my new Iranian neighbors) that the term "Aryan" is cognate with "Iran" the country. "Iran" in Persian means something like "Land of the Aryans", and that in 1935 the government of Iran asked its diplomatic partners to refer to it as Iran instead of Persia because of the popularity of Aryan racial ideologies.
ok but the world-wide "suppress melanin/blue eyes" gene emerged in that same part of the world (north of the Black Sea) some 10,000 years ago, so it seems that the Aryans could have been as blue eyed as anybody.

And they certainly weren't the 'Aryan ideal' as pictured in racist propaganda.
