JP, would you be open to the idea of willful genetic manipulation of prehistoric humans? That could be thought of as an assisted evolution. Scientists are doing this now by experimenting with chimeras. The only thing that stops them are term limits on the use of embryos.
Evolution is not just about change for the sake of change but the whole concept of evolution is an improvement over it's genetic predecessor. And if a species wants improvement to survive it does indicate the possibility of some sort of primeval intelligence. That's why cancer is not evolution; it's cells gone wrong, but a fish out of water and growing legs is an improvement were there evidence for this.
