Persistalsis
Right, why do we have that redundant swallowing mechanism? ~~Did enough people choke while eating upside down to make a difference? Wait, this is from our ape-y ancestry?~~
My guess it's even older than that. My bullshitspiration is that peristalsis enabled more complex digestion when our quadruped ancestors needed more nutrition options.
Probably also helps with eating while lying down.
Gulping in.
This is the kind of question that fuels science.
Good job he's not a bird
Obviously they've never seen the Mr. Wizard's World episode where they ate upside down.
Memory unlocked. https://youtu.be/bC6jJnVe1LI?t=16m28s
I feel like there was another episode covering this where they had them try to drink upside down, or am I mistaken?
Here you go, OP. Have fun. (open-access)
