Continuity mistake: The person responsible for background shots while anyone is in a car driving, is grossly negligent in their continuity. Very rarely do Bones & Booth drive down a street without the background changing rapidly from urban to rural streets, and back.

Continuity mistake: When Derek takes Booth's watch, he holds it up over his index finger to show Booth. When Booth grabs the watch, Derek is now holding it with his thumb and index finger. (00:18:40)
Answer: Since the palatine bone is a bone that helps form the mouth it has a lot to do with speaking. The shape of it differs a lot depending on your ethnic background. I would guess that they, in the show, meant that the person's bone tells that they were Japanese and that it was "made for the purpose of speaking Japanese." That's what I'd assume anyway. I've studied molecular biology though, so I'm not an expert on bones.
