Fish get their oxygen from water. Most of them have two pairs of nostrils, a forward facing set for letting water in and a pair of exhaust pipes for letting it out again. The question is, if humans evolved from fishes, where did the other pair of nostrils go? The answer is that they migrated back from inside the head to become internal nostrils called choannae – Greek for funnels. These connect to the throat and are what allow us to breathe through our noses.
