Abstract :
I do not wish to trivialize Charles Darwin\´s great discovery: Evolution. In 1859, it was a revolutionary theory, but in today\´s sophisticated environment, biological evolution seems to be an obvious process. Succinctly summarized as "survival of the fittest," it has become much more than a "theory." The "theory" view is deprecatingly offered by scientific illiterates. My argument is that evolution is a natural law. First, it is a law because there are no exceptions; by definition, the survivors of any system are the elements that were the fittest. Second, it is "natural" because it is a law that applies to all mechanical and/or chemical systems. These are arrangements in which several outcomes can occur but, gradually, the "unfittest" outcomes are eliminated. The "natural law" is not restricted to living creatures.
