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.

Anything subject to replication, mutation, and limited resources, will evolve. Memetic evolution makes perfect sense.

Agreed.  That's why the term "meme" was created.

Ah, that's something completely different. Moonish women being like that has to do with sexual selection. I suppose there are more complex ways that culture influences evolution but I think in the end it's all just complex forms of sexual selection.

That's a pretty big claim there. At the very least the unit subject to replication would have to influence the properties of its carrier (the way a gene affects the properties of its organism) but I'm pretty sure it doesn't end there.

Even so, ideas are free to copy (IP law joke goes here), there are no limited resources.
