Factual error: In the interview room with the father, they show him the locket which is in an evidence bag. We next see the father holding and opening the locket. There is no way they would allow him to open and remove the locket from the evidence bag. (00:07:15)
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.
