    In nature, living things evolve through changes in their DNA. In an
    animal like a chicken, DNA from a male sperm cell and a female ovum
    meet and combine to form a zygote — the first cell of a new baby
    chicken. This first cell divides innumerable times to form all of the cells of
    the complete animal. In any animal, every cell contains exactly the same
    DNA, and that DNA comes from the zygote.

    Chickens evolved from non-chickens through small changes caused by
    the mixing of male and female DNA or by mutations to the DNA that
    produced the zygote. These changes and mutations only have an effect
    at the point where a new zygote is created. That is, two non-chickens
    mated and the DNA in their new zygote contained the mutation(s) that
    produced the first true chicken. That one zygote cell divided to produce
    the first true chicken.

    Prior to that first true chicken zygote, there were only non-chickens. The
    zygote cell is the only place where DNA mutations could produce a new
    animal, and the zygote cell is housed in the chicken’s egg. So, the egg
    must have come first.
