Question: When Doctor Brennan is examining the victim's skull, she states that a "straight suture across the palatine bone" indicates that the victim was a native Japanese speaker. I've studied linguistics, but I've never heard of a person's native language actually affecting their anatomy. So, for example: would a person of Japanese heritage who was born and raised in the US and spoke only English be distinguishable from a person who grew up in Japan and spoke only Japanese, purely by their palatine bones?

Question: I don't understand why Pullo is so angry with Vorenus and thinks he needs to apologise. Having fought in Caesar's army for as long as Pullo has he would be very well aware of the repercussions for what he did, why would he blame Vorenus for abiding the law and doing what is required of him as a centurion?
Answer: Its Pullo's nature to resent people of higher standing than him. His jealousy of Vorenus in later episodes, which in part leads to their falling out, is proof of that. From Pullo's point of view, Vorenus just got better breaks to get where he is in the army and so, isn't really his superior. That, plus his natural arrogance is explantion enough for his behaviour in spite of the fact that he broke the rules and was being fairly punished.
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.
