Something I learned just now is that the problem / paradox evidently goes back to Ancient Greece! [WP]
But yeah, I think we could consider it solved (among rational people) with the development of the Theory of Evolution, combined with a better understanding of zoology and various other fields. So, maybe by 1900? And I suspect that the ancient-ness of the problem is a big reason people still use the expression, even though it’s been shown to be a faulty question for over 125yrs.
Btw, internal eggs to my understanding are as old as sexual reproduction, over 600M years ago. External, shelled eggs go back over 300M years ago. Galliformes (chickens and relatives) go back about 85Myrs.
