What is the body trying to accomplish? How are they caused? What is actually happening? And why are they “contagious”?

Yawns are most likely contagious among social creatures like humans, dogs, etc. If you see someone else yawn and you’re comfortable with them, it makes you want to yawn to show you’re also comfortable and to fit in. However, this is just a theory. Mythbusters did an experiment with this and found yawns can be contagious even if people don’t see each other.
