Other mistake: When Hodgins runs up to the platform near the end, to discuss the debris of the watch, the security card reader goes off (as if someone were swiping their card). But there's nobody near it, and we see Hodgins step up the centre of the stairs, nowhere near the machine. About 30 seconds later, Angela comes up as well, but we hear the reader beep, and within a second or so, she's already well up on the platform, much further than possible based on her casual walking speed coming into the scene.

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.
