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."
Why did the chicken cross the road? The riddle appeared in an 1847 edition of The Knickerbocker, a New York City monthly magazine:[1]
