    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 used to have a dog that would yawn with a little whine whenever she was frustrated. It was adorable.

      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 guess it’s just a biological indicator to remind you that you’re tired. In modern life people don’t usually find their jobs exciting. We were hunter and gatherers a few thousand years back and I bet they didn’t yawn as much hunting prey. Maybe when sewing or making clay pots. Of which I am smoking a lot of currently. What were we taking about again?
