Natural selection is only interested in behaviour, as only behaviour matters for survival. A meaning zombie, by definition, would behave just like a real human being, and thus would survive just as well as a real human being. Natural selection has no interest in the quality of your inner life, so long as you’re going to do the kinds of things that’ll make you live longer and pass on your genes. On the face of it, therefore, we cannot explain in evolutionary terms why we are not meaning zombies.
Ignores the evolutionary advantage of memes, which require communucation and memory skills beyond our genes.
