It is said that the average human has four nostrils. You can only see two of them though; How do you think we breathe in through our mouths? Fish have a set of nostrils to breathe in, and "exhaust pipes". If we evolved from fishes then that means we still have another pair of nostrils. While we evolved, they went back into the head to become internal nostrils-allowing us to breathe in through our mouths. To smell things we only use our external ones though.
