Release Message:  Which came first, the chicken or the egg?

Description:  Aristotle (384_322 BC) was puzzled by the idea that there could be a first bird or egg and concluded that both the bird and egg must have always existed: If there has been a first man he must have been born without father or mother _ which is repugnant to nature. For there could not have been a first egg to give a beginning to birds, or there should have been a first bird which gave a beginning to eggs; for a bird comes from an egg.
