I have a theory about yawning:

So you know how yawns are kinda contagious? And also, you know that little gasp you make 8n your throat when you almost drop something or something terrible happens? And how that sound sounds sorta like a yawn?

Well, in cavemen times, I think that sound was a signal of danger. And in order to communicate you understood, you made the noise back. Yawning when we’re tired communicates that oh no, take over because we’re tired. So yeah. That’s my theory.
