Aliens

The view of the biological anthropologists can be likened to the film series Star Wars, whose aliens have different physical anatomies but are rather disconcertingly united by an unshakable human nature. The view of the cultural anthropologists is more that of the film Invasion of the Body Snatchers, whose protagonists take human form but retain their alien natures. (the film that got it right is Independence Day: If not human, it correctly suggests, everything is alien.)
