EDIT : It seems as no one understood what i was talking about and maybe its my fault for not elaborating . I always thought chicken was a metaphor for this paradox and not really meaning chicken as a specific spiece . So my question is how did the ancestor of chicken came to be if it was born (egg) wouldn’t it need a parent or if it was a parent (chicken ) woudn’t it need to be born ? Or did all the creatures start out as bacteria and climbed out from ocean through evalution if so why isn’t any new species being born this way or am i missing something ?
But you don’t know if the proto chicken’s offspring is a different kind of chicken until it’s hatched. That’s how you get a new species.
It’s a bit of a Schrodinger’s egg situation I guess.
For what it’s worth it’s possible to test the contents of an egg, but it’s moot because it doesn’t actually matter when we know. It exists independent of observation.
