You might think you have two nostrils, but you'd be wrong. You have four. This discovery came from observing how fish breathe. Fish get their oxygen from water, and most of them have two pairs of nostrils, a forward-facing set for letting water in, and a pair of exhaust pipes for letting water out. The question is, if humans evolved from fishes, where did the other pair of nostrils go? The answer is that they migrated back inside the head to become internal nostrils. These connect to the throat and are what allow us to breathe through our noses.

Damn, what?

I really don't know how I feel about this scientific discovery, and it's making me not want to breathe.

I feel like I knew this. When you said it I was like, four, yeah four, two up top, two down below. Right? Thank goodness, because that would be creepy.

Well they have to be connected to some other holes right? So yeah it makes sense. And also kitties have have that and they smell through that too so sometimes they open their mouth to smell.

What the fuuuuck I had no idea this makes so much sense that we used to be mermaids Hey you gotta keep making these these like random facts. Yeah, this is awesome.
