Sure, that's not evolution in the proper sense of this word. Seems to me, the more important, bigger point is that there are a number of cultures or societies or whatever you want to call it, that are very quickly on their way out, that's just math, below replacement and people will die out eventually. So the question is, will they be replaced by other cultures that are not on that trend yet, or will the whole humanity follow, because personally i just don't see how can you fight this trend where it already exists and human life is not likely to be extended much beyond 80 years in the foreseeable future.
