By definition natural selection is a selective process (selecting from already existing information), so is not a creative process. It might explain the survival of the fittest (why certain genes benefit creatures more in certain environments), but not the arrival of the fittest (where the genes and creatures came from in the first place). The death of individuals not adapted to an environment and the survival of those that are suited does not explain the origin of the traits that make an organism adapted to an environment. How do minor back and forth variations in finch beaks explain the origin of beaks or finches? Sir I demand to know how natural selection explains goo to you evolution?
