The "Stoned Ape" theory of human evolution
Perhaps the most famous of Terence McKenna's theories and observations is his explanation for the origin of the human mind and culture. McKenna theorized that as the North African jungles receded toward the end of the most recent ice age, giving way to grasslands, a branch of our tree-dwelling primate ancestors left the branches and took up a life out in the open—following around herds of ungulates, nibbling what they could along the way.
Among the new items in their diet were psilocybin-containing mushrooms growing in the dung of these ungulate herds. McKenna supposed that psilocybin's verified enhancement of visual acuity was instrumental in the human dominance over prey. He also argued that the effects of slightly larger doses, including a physical sexual arousal—and in still larger doses, ecstatic hallucinations and glossolalia—gave evolutionary advantages to those tribes who partook of it. There were many changes caused by the introduction of this drug to the primate diet. McKenna theorizes, for instance, that synesthesia (the blurring of boundaries between the senses) caused by psilocybin led to the development of spoken language: the ability to form pictures in another person's mind through the use of vocal sounds.
About 12,000 years ago, further climate changes removed the mushroom from the human diet, which McKenna argued to result in a new set of profound changes in our species as we reverted to pre-mushroomed and brutal primate social structures that had been modified and/or repressed by frequent consumption of psilocybin. However, in McKenna's theory, the psilocybin-induced dominance of humans over other species remained, despite our supposed devolution.
