It seems strange to me that scientists and other extremely intelligent people would come up with a theory that is based on something that in very few instances in nature is beneficial and that has never yielded a product that is different in scientific classification besides in species.
I can't figure out exactly what he means. What is not beneficial--the theory or evolutionary change? Beneficial to whom? People? The particular life form?
What did you take it to mean, Paraasomnium?
