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 Ainu still have a different appearance from other Japanese people." is true, false, or inconclusive?
Answer: Inconclusive
