What is happening with humans right now is natural selection.  We are not immune, just arrogant enough to think the rules of nature do not apply to us.  Our need for food, water and inevitable death would indicate that we are very much subject to the laws of nature as much as we ever were.  We are just better at denying this to ourselves.  We are being used by nature to create inorganic forms of intelligent life which is likely what the universe will evolve into since it does not have the weaknesses of biological life.  Humans want to believe we are creating nature, but the reality is that we are still mother nature's bitch and always will be.
