The chicken vs egg question has never been about chronology or science.
It’s been about religion vs science.
Science says the egg came first: something nearly imperceptibly not quite a chicken laid an egg that hatched a chicken. That’s how evolution works, with the egg coming first.
Religion says a god poofed a chicken into existence. The chicken came first, and only ever laid pure chicken eggs. The eggs will forever hatch a chicken and nothing but a chicken.
That’s the chicken vs egg thing. It’s not a puzzle at all, it’s just science vs religion.
I don't like this because it's not addressing the actual saying. Obviously the saying is about chicken eggs specifically.
But I've always felt obviously the egg came first. The first chicken was born in an egg, so the egg came first. That egg could have been produced from a creature with a mutation which caused it to produce the first chicken egg when it is not itself the exact same species.
Over time, a population of proto-chickens lay eggs with unique genetic variations that randomly direct the population towards laying eggs that result in modern chickens. The egg comes first, and it's a whole bunch of them
The snake and lizard branch is wrong. I care very much about the accuracy of memes, and I have to point out that many lizards are more closely related to snakes than they are to other lizards.
I haven't understood how this question seems difficult to so many. Not trying to put anyone down, but chicks hatch from eggs. In order for a chicken to be classified as a chicken (as we know it to be), it would have hatched out of an egg.
