it's not evolution. It's mostly a result of natural selection at its finest. A Darwinian theory, that does go hand in hand with the theory of evolution, but is not quite the same. Evolution tends to require the realities of natural selection in order to allow evolution to occur, but natural selection doesn't always lead to evolution. We aren't changing as a species, it's simply natural selection taking place.
It's natural eugenics to sum it up. Those with the best genes tend to have better chances of reproducing, and those good genes get passed on to potentially a larger group of offspring.
In most species, this process would be extremely quick. However, we have these things called ethics. People who wouldn't normally be seen as fit to reproduce, find others who are equal, and those segments of "bad genes" get to live on. Not that there is really anything wrong with that, because we don't have the natural challenges that force us to fight for the survival of the species in this modern day. Just an observation that notes how greatly different we have behaved in comparison to the history of other species.
