"Well, there is another explanation ..." Albert said with an odd expression, "Among the muggles, a group of professional scientists has discovered a substance, a protein that catalyzes the formation of eggshells, and this protein is only found in the ovaries of chickens. That to say, if there was no chicken, there was no such protein, the formation of eggshells would be impossible, and the formation of eggshells would prevent the hatching of the chickens successfully, hence they conclude that the Chicken came first.
