The Skull in the Desert - S1-E17

The Skull in the Desert - S1-E17

The Skull in the Desert - S1-E17
Continuity mistake: During the scene when Booth and Bones are driving to tell Angela that her boyfriend is dead, the scenery behind Booth jumps suddenly mid shot. Initially the scene is of a wide plain, then suddenly a mountain range appears. This scene was obviously shot on a sound stage, with the scenic background being projected onto screens around the vehicle, an old trick in movie making. It seems that somebody mistimed the loop of the tape they were using. (00:12:30)
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.
