No. I'm saying that the effects of psilocybin claimed by Mckenna, and which are required for his theory, do not exist. Specifically, for example, psilocybin actually reduces vision, rather than improving it [1] : which invalidates Mckennas first quoted point above.

This isn't a question of "evolutionary psychology", but of neuroscience.
