A "Law of Biological Conservation" is developed in the context of the well-known Laws of Thermodynamics. It is asserted in this Law that the total information implicit in all living creatures at a given instant cannot exceed the total information coded upon all the genes of all their cells. As a corollary of such a law, it becomes obvious that creation requires a Creator because the information implicit in these living beings today cannot exceed the total amount of information of all kinds which was required to specify the whole of the original creation. Evolutionists should face this issue and consider its implications.
