what comes first the egg or the chicken
Chicken or the egg If the question refers to eggs in general, the egg came first, as the first egg-laying animals evolved millions of years prior to birds.[1] If the question refers to chicken eggs specifically, the answer is again the egg, but the explanation is more complicated. An animal nearly identical to the modern chicken (i.e., a proto-chicken) laid a fertilized egg that had DNA identical to the modern chicken (due to mutations in the mother's ovum, the father's sperm, or the fertilised zygote).[2][3] Put more simply by Neil deGrasse Tyson: "Which came first: the chicken or the egg? The egg â€“ laid by a bird that was not a chicken."[4] For Richard Dawkins, "The chicken is only an egg's way of making another egg."
