The way that many people discuss 'evolved humans' is starting to annoy me. Allow me to discuss a few things I am are that lots of people already know but some people apparently do not:
1. Evolution and natural selection are processes which take thousands of years. Vols did not pop up one day having skipped thousands of years of biology. Very likely, each of us has a series of mutations that gives us out powers. These mutations may or may not survive into future generations, either because any of us does not have offspring, or because of epigenetics or what have you, they are not inherited or displayed. To evolve, we have to a) survive and b) have offspring who survive.
2. By basically every definition of species, including morphological (do they look alike?) and biological (can they have viable offspring) vols are human beings.
3. 'Survival of the fittest' is an pop science manner of describing natural selection. Nature selects traits which are best suited to a particular environment. A lion and a polar bear are species which evolved to meet very different landscapes. If you put a lion in the Arctic and a polar bear in the savannah both would die. Neither is better or worse than the other, they are just different.
4. Nature and evolution are cold and cruel and uncaring, if beautiful. Just because it happens in nature doesn't mean it should be emulated.
5. Social Darwinism was gross in the 1800s and it's gross now.
If I'm mistaken about any of this, apologies and correct me from a biological standpoint. This post took me a while because I know most of these words in Czech and maybe I misunderstood I would recommend reading The Selfish Gene by Richard Dawkins, because it was one of the more interesting things I studied while homeschooled.
Also, Karim, shut up.
