Evolution doesn't work that way.

I know it's very science-fictiony and cool to think about preparing or manipulating the human race (and whatever "race" is to replace and/or supplant it) for the future enviroment, but it's not science. And it's not how evolution works.

I think you can rest easy -- the mutants of evolution were NEVER prepared ahead of time in anticipation of a future environment. We won't either. It can't be done.
