A Quora answer pointed out something to me, I'd pull it up but Quora makes it really hard to search through your previous upvotes, something that people regularly miss about ants. The worker's stomachs is separated from their mouths by a very, very small opening. Meaning they can't eat solid food. Instead they chew it and regurgitate it so the larvaes, who don't have such a constricting path to their stomachs, can finish digesting it. Worker ants eat the liquid waste of the larvae. So there's a body-morphological explanation for eusociality.
