Is there a field of study, or a segment of one, that teaches how to help identify a person's nationality through facial features? Or maybe there's a book out there about such a thing? For example, in the show "Bones", she's always able to immediately identify if skeletal remains are Native American, Hispanic, Asian, European, Oriental, etc. What science would a class about something like that fall under? Or maybe someone can suggest a book about the subject? Thanks!
