This Ethnobotany online course explores the compelling hypothesis that psychedelic substances, especially psilocybin mushrooms, played a significant role in human evolution and the development of consciousness. Moving beyond the controversial “Stoned Ape” theory, the course examines a multi-faceted array of evidence, from primate behavior and archaeological findings to cutting-edge neuroscience and clinical research, to build a case for the profound impact of psychedelics on our species.
We’ll investigate how psilocybin’s effects on the brain, particularly its influence on serotonin and dopamine systems, may have facilitated the unique cognitive leap that distinguishes humans from other primates. This includes exploring its potential to enhance visual processing, foster cognitive flexibility, and promote the emergence of novel mental representations. Furthermore, the course will delve into the social and cultural implications of psilocybin use, examining its potential role in fostering empathy, promoting prosocial behaviors, and driving the evolution of ritualistic practices and shamanism.
Finally, we’ll consider the contemporary resurgence of psychedelic research and its implications for treating mental health conditions, fostering personal growth, and navigating the complexities of the modern world, ultimately reflecting on the potential for psychedelics to contribute to a more conscious and interconnected future.
What you’ll learn:
- The Intertwined History of Humans and Psychedelics
Explore the evidence for ancient psilocybin use, tracing its potential influence on human evolution from primate ancestors to the development of early hominid societies. - The Neuroscience of Psychedelic Experiences
Understand the neurobiological mechanisms of psilocybin, its effects on key neurotransmitter systems like serotonin and dopamine, and how these changes relate to altered states of consciousness, enhanced creativity, and social bonding. - The Evolution of Shamanism and Spiritual Practices
Examine the potential role of psilocybin in the development of shamanistic traditions, ritualistic behaviors, and the emergence of religious beliefs across diverse cultures. - Adapting to the Cognitive Niche
Discover how psilocybin may have enhanced cognitive flexibility, visual processing, and social intelligence, contributing to human success in the cognitive niche and the development of shared mental models - The “Dopaminergic Personality” and Social Evolution
Explore the concept of the dopaminergic personality, its connection to shamanism, and how psilocybin’s influence on dopamine may have shaped human social behavior, cooperation, and group dynamics. - The Future of Psychedelics
Analyze the contemporary resurgence of psychedelic research, including its therapeutic potential for mental health conditions, and consider the ethical and societal implications of integrating these powerful substances into modern society.

Michael James Winkelman, Ph.D. (University of California-Irvine), M.P.H. (University of Arizona) is retired from the School of Human Evolution and Social Change at Arizona State University. Winkelman engages cross-cultural and interdisciplinary research on shamanism and its biological bases in Shamans, Priests and Witches (1992) and Shamanism: A Biopsychosocial Paradigm of Consciousness and Healing (2010).
He addressed the therapeutic applications of psychedelics in his co-edited Psychedelic Medicine (2007) and Advances in Psychedelic Medicine (2019).
Winkelman examined the intersection of psychedelics and the evolutionary origins of religion in his co-authored Supernatural as Natural (2008) and a Journal of Psychedelic Studies Special Issue on Psychedelics in History and World Religion (2019).
He has also explored the applications of shamanism and psychedelics to treatment of addiction.
His most recent work involves a special issue of Frontiers on โPsychedelic Socialityโ where he publishes an article on Psychedelics, Sociality and Human Evolution. He currently lives in central Brazil where he lives as a gentleman farmer practicing permaculture and continues his research.
