That is indeed what it seems (ie, what you said), although all the answers are not in. Didn't the Ainu supposedly originate in Europe and not Asia?

I believe the current theory is that, some 60k years ago, a human population developed in west-central Asia [from ultimate African sources] from which the Ainu proceeded very early all the way East to Japan and Sakhalin, etc. This is so early that everybody was Caucasoid. [proto-Caucasoid, I should say.]

Later, from this group, the whole Mongolian race somehow developed and headed east and southeast. Also, from it the Turks and Finns, etc. headed west towards Europe...

European races except the Finns, Hungarians, and other recent arrivals from Asia are thought to have proceeded from the Middle East direct to Europe some 30k years ago with no reference to the Central Asian distribution point.

IIRC, Kennewick Man has more affinity to the Europoid than to the Central Asian descendants such as Turks, Finns, or Ainu...
