I didn't say memes thwart biological evolution, I said they evolve faster. So any niche that can be, will be filled by a meme before our biology changes.
You are right this wouldn't reverse pre-existing stuff. But what pre-existing things were there? Reflexes? Check. Face recognition hardware? Check. High level human interpretations of touch? No.
You say memes are a top layer. That's what I said originally! And I made an analogy you have not answered: Ruby is a top layer, on top of an assembly language, and C. And the fact is, if you switch to a platform with a different assembly language, Ruby stays the same. The lower layers aren't important once you abstract them away.
You say we have a "primate brain" but aren't clear on what this means. We have a brain with universal creativity. No (other) primates have that. It's a different kind of thing.
