Glen, I really don't understand how you can separate a person's genetic compostion from his language ability.  Your African-American should have a stronger affinity for the language of his/her ancestral home than he does for the English language.  The same applies to cultural affinity, food preferences etc.  If the Ainu derive their genetics from the mainland west, that's where scholars should search for the Ainu language.

Subject: [nostratic] Ainu, language and genetics

No one in their right mind considers genetics and language
interchangeable concepts nor should anyone assume that they always
go in the same direction. Period.

So, while the Ainu may derive much of their genetics from the
mainland to the west, the origin of their language must be
examined seperately and unbiasedly.
