Which came first? The chicken or the egg?
The answer reached by a team of a geneticist, a philosopher and a chicken farmer has settled the question once and for all.
Actually the logic is pretty compelling. Since species jumping mutations are theoretically not possible in an adult animal, whatever changes occured which created a chicken must have occurred in the zygote, which became embedded in the egg, where the embryo developed into a chicken. So the egg was laid, the embryo developed, and a chicken hatched. Voila!
But this begs the question. Was the zygote before the egg? If so, and if DNA is all that defines an animal, wasn’t the chicken zygote created before the egg was formed? If so, then wouldn’t the chicken have come before the egg?
This is perilously close to the abortion question of when an embryo becomes a person, isn’t it?
