Err, I dont think a single mechanism exists either to make DNA or proteins... so I'm not sure where that comes from. However in the case of "learning", we're talking about the macro and micro physical structure of the brain encoding vast amounts of sensory-motor models of its environment, etc. We're talking about the brain-body-environment as the site of mood, emotion, desire, belief, imagination, etc. We're talking about that thing when given vallium (a simple chemical effect) has extremely complex net effects on mood, desire, belief, etc. Inasmuch as CO2 has likewise, extremely complex effects. The statement that the relevant actions of the brain-body system here are complex is scientifically uncontroversial. Yet, pseudoscience continues -- because some researchers ignore (or are ignorant) of the methodological implications.
