In March 2006, on the occasion of the release of Chicken Little on DVD, Disney convened a panel to put an end to the long-standing riddle: Which came first, the chicken or the egg? The verdict was unanimous. “The first chicken must have differed from its parents by some genetic change [that] caused this bird to be the first ever to fulfill our criteria for truly being a chicken,” said John Brookfield, an evolutionary biologist at the University of Nottingham in England. “Thus the living organism inside the eggshell would have had the same DNA as the chicken that it would develop into, and thus would itself be a member of the species of chicken.” What we recognize as the DNA of a chicken exists first inside an egg. Egg came first.
