In this article the author comments on some of the latest French publications concerning the evolution theory and interactions with molecular biology. Georges Salet’s important work, Hasard et Certitude is stressed as a challenge to Hasard et Ne’cessite’ written by the Nobel Prixe laureate Jacque Monod. Georges Salet analyzes the problem of transformism from a mathematical viewpoint in light of studies made by Borel. Salet proves that the formation of new organs and/or new functions by a mere game of chance in living beings is mathematically impossible. The evolution theory cannot be supported from a scientific point of view, but is based on an atheistic prejudice. It should be obvious to everyone not influenced by artificial philosophies or atheistic prejudices, that the complex and wonderful structures of living beings could not have been the result of a game of chance. A watch or any machinery is built in view of a plan by an intelligent watchmaker or engineer who has prepared and made it. It is also evident that animals and plants are much more complicated and better adjusted than any machine ever built by man. It is paradoxical to think that plant and animal parts and functions, which are so exact and complicated, could be simple products of chance combination of some of the materials of the universe.
