The Ethnosphere - What And Where Is Human Nature, Really?

I am in full agreement with almost everything Pigliucci says in the above-linked essay about "human nature." I am concerned, however, about what I see as his opinion that a good (unified, comprehensive?) theory of cultural evolution may one day be established.

"...despite much interest and a number of valiant efforts — we really don’t quite have a good theory of cultural evolution at hand."

Though he doesn't directly address the reasons for this lack of a good cultural evolutionary theory, Pigliucci is right about this.

The lack of a "good" cultural evolutionary theory, however, has less to do with our not yet coming up with one than it does with our scientistic expectations. That is, the incorrect belief and insistence that the patterns and practices of human cultural adaptation, extant cultural adaptations and all of those throughout history and prehistory, are reducible to a unified theory containing equations, formulae, and genetic mapping in a manner similar to what mathematics, physics, chemistry, and biology apply to other phenomena.

The reason we don't have a good theory also, and more importantly, has to do with the complexity of culture as an adaptive process.

Culture and cultural evolution are not fully explained by the Darwinian-Mendelian theory of biological evolution, or more recent related efforts called evolutionary psychology and memetics.  Worse, the approaches taken and speculations used in most of these two latter-day efforts are misinforming the public.
