Don_DickleHas society or scientists ever solved definitively the Chicken and the Egg theory? Or is it just like a whose on first thing?
krank55At that point the genetic difference would be too small to not call that bird some sort of chicken.
Nope.
There will be an exact egg that contains the first chicken (defined as an animal that can fuck other chickens and produce offspring IIRC), that came before the first chicken because the chicken was in the egg.
I’m no biologist, but I’m pretty sure this ignores how fluid the evolution is from regular bird to proto-chicken to chicken.
By the well ordering theorem, no matter what you choose as your definition of “chicken”, there must be a first.
