"The Ainu look like Caucasian people, they have white skin, their hair is wavy and thick, their heads are mesocephalic (round) and a few have grey or blue eyes. However, their blood types are more like the Mongolian people, possibly through many millennia of intermixing."
I always thought that there was a connection between the Ainu and the Inuit. I noticed some similarities in their artwork long ago.
