TIL yawning is observed in almost all vertebrate animals and is "contagious" across species. There is no consensus on why yawning occurs.

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.
Ay yo so I was bout to tell you how that's all wrong, but then you go throwin out words like "perlocution" and now I realize you probly know what the fuck is up, so I'm just gonna trust.
Perchance.
You can't just say perchance.
I think they just did.
Perchance they can
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!
You're thinking of psychopathy.
A true psychopath (someone with no real empathy) will not catch a yawn as it requires an empathetic response
