Evolution affects humans too.

I present to you 5 facts.

1: Civilisation started after early homosapiens migrated from Africa into hostile ice age Europe.
2: Adaptions occur more frequently when an animal enters a new environment.
3: By far the most important adaption in recent human evolution is the brain. A neanderthal with a human brain would not be significantly worse or better off than a human.
4: Physical adaptions take longer to evolve than the simple increase in size of the neo-cortex.
5: Humans do have a plethora of physical adaptions to various environments.

Now that Civilization shelters the weak and stupid, human evolution will start to diverge as the inferiors breed with more inferiors, and the more intelligent keep to themselves

Eventually, we will split into two.
