Continuity mistake: Booth and Brennan arrive at the crime scene in the beginning of the show.

Cut to the next shot and the trunk is fully opened. (00:02:10)

Other mistake: Just after Booth realises the drive by was done to help the gang member escape, we see him run up to Bones who's on the forensic platform. However Booth doesn't swipe his pass to allow him entry. Whenever anyone walks up without swiping the card, a siren goes off and the security guard stops them. Regardless of who they are, as demonstrated in several episodes. (00:06:00)

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.
