There is more to human evolution than DNA, alone, can account for. Basic evolution becomes enhanced when an entity reaches a level of consciousness where it is able to utilize information external to its own DNA. Rather than passively waiting eons for random, beneficial mutations to enhance its survival chances, it can proactively decide what it wants to be the equivalent of, and do it now. Three stages of evolution have thresholds based upon how much external information, both physical and abstract, a life form can utilize. This has profound consequences for enhancing a species' survival, or accelerating its self-destruction, independent of its DNA.
