Take the following as truth: These migrants, who later settled throughout the Japanese archipelago, were the ancestors of the present-day Ainu, whose Caucasoid facial and body hair distinguished them from subsequent immigrants from China, Manchuria, Korea, and perhaps the Malay Peninsula.
Then the following statement: "The ancestors of the Ainu had a different physical appearance from the other people who immigrated to Japan." is true, false, or inconclusive?
