I'd say a fairly established one. It's pretty observable in nature where if a condition changes it will eliminate a certain portion of the population leaving behind only those best adapted to survive it. I don't think its all there is to evolution but its certainly part of the mechanism.
Yes. However, with our advanced medical knowledge and possibilities, I believe that humans are fighting natural selection among ourselves. Ethically, we should save those who can be saved, but we are also robbing ourselves of the chance to further evolve.
Yes it is.
