Is it possible that psychedelics brought about human language, our huge brains, and essentially all elements of our modern culture? Well, I made a video recently about what psychedelics do in the brain, but a lot of you felt bothered by the statement I made about this idea, the Stoned Ape Theory, being bad. So let’s talk about it! What is the Stoned Ape Hypothesis, and why exactly is it a bad theory? And if magic mushrooms aren’t the answer to how our human brains evolved, what are some of the theories that have maybe a little more support? Pascal Gagneux, PhD, a professor of anthropology and pathology at UC San Diego, joined us to talk about human origins, our relationship to psychedelic substances, and how much chimps love (ordinary, non-magic) mushrooms.
