Well, in my science class this old dude was experimenting that. Someone yawned on stage and 55% of the audience yawned too. When he noticed that he started experimenting. He thought it might be the way your mouth moves when you yawn, so he made a video clip of a persons mouth yawning and played the sound affect of a yawn, but then only 5% of the people yawned. So, no one actually knows why. This guy also experimented other things about yawing, but never found his answer.I read in a book it was a group thing for you to tell the group you're tired and everyone to have a rest. See the book why is snot green.
