You didn't address the point I made about motivations for changing oneself. Look, you can never be "outside" of the evolutionary process. Yes, a species could potentially decide what they evolve into, but they are still acting within the framework of natural evolution because the desire to change because of the environment in itself is a part of natural evolution. The only difference is, it could be a conscious change instead of an undirected one. It doesn't mean that they are somehow outside of natural evolution, only that they are conscious of the process, which we already are.
