    Seems like if you read between the lines, there’s a certain commonality in increased respiration/alertness, stress response and showing of teeth that solves a common need across species. When a subject recognizes a lack of alertness, a present threat or the need for aggressive action in the near future, a yawn can help prepare for that while also giving pause to those who might be threats and/or potentially paralyzing prey. The failure in consensus here appears, to me, an inability to describe those seemingly disparate needs as related to the physiology that drives them. Not a lack of understanding, so much as a deficiency in perlocution.

      I’ve read that people with autism are less likely to catch a yawn. Not sure if that’s true.

      I’ve taken meds that caused uncontrollable yawning. That’s super annoying!

          Yes, but can you catch a yawn from someone else? That’s the claim about autism, that someone else yawning does not tend to make people on the spectrum yawn. I have no idea whether or not that is true.

        You’re thinking of psychopathy.

        A true psychopath (someone with no real empathy) will not catch a yawn as it requires an empathetic response

      That’s pretty common among cats and dogs. Sometimes the clever ones will hide a bite they decided against at the last second with a yawn, too.

    I watched a video a couple years ago where they did an experiment with chimps. I thought they concluded that the “cantagious” yawning has to deal with the animals empathy and wanting to be like others, it was a social thing in pretty sure. I have no idea where to even find this video though so take that with a grain of salt

      Mythbusters rated contagious yawns as plausible, I believe, because they observed multiple instances of yawns spreading throughout a building where the participants couldn’t see each other.

      As someone with asthma and lowered ability to cycle out CO2, yawning has always helped me restore the “full” feeling and your comment just made everything snap into place.

      The primary driver of suffocation panic, pain, and feeling of air starvation isn’t the lack of oxygen but CO2 buildup. It makes sense that yawning on command could then help alleviate the symptoms of CO2 buildup in asthma sufferers.

        Might be a group protection mechanism to indicate low oxigen in crammed spaces qith many individuals. In addition to that could be a geoup trigger for rest.

      I always thought it was due to clearing the lungs out or to regulate them but then I saw a turtle yawn under water. I then thought it’s ancestors wouldn’t have been swimmers so maybe it’s instinctive still, but then it would need a mechanism to prevent water inhalation. So why retain the yawn.

      Perhaps as you say it’s more about visual communication to others around you.

      It seems most sensible to me that it serves a bunch of uses: clearing the lungs, alerting yourself and others that you’re tired and probably need someone else to take over, social bonding, spooking predators…

      The big one for me is night watch, if you’re on watch and notice yourself yawning then you know that it’s time to wake someone else to take over, because if you fall asleep that’s very dangerous.
