Psychedelic fungi containing psilocybin may have played a role in the development of human consciousness a scientific review has suggested.
The study, published in the journal LILLOA, analysed multiple studies involving psilocybin, psilocin and human consciousness. Taking a multidisciplinary approach spanning studies from the fields of biology, ethnobotany, and neuroscience researchers found that psychedelic mushrooms, specifically the Psilocybe genus of the Hymenogastraceae family, had the “potential to trigger significant neurological and psychological effects” in humans.
The findings support the Stoned Ape Theory, a hypothesis proposed by ethnobotanist Terence McKenna in his 1992 book Food of the Gods. McKenna suggested that psychedelic mushrooms were the major evolutionary catalyst behind the rapid expansion of human consciousness.
“At the cerebral level, psilocybin affects various areas, such as the prefrontal cortex, the hippocampus, and the anterior cingulate cortex,” the study authors wrote. “The hypothesis that psilocybin mushrooms may have intervened as a factor in the evolution of human consciousness, either as catalysts for mystical experiences or as drivers of cognitive processes, raises profound reflections on the ancestral interaction between humans and their environment.”
The paper highlights how numerous ancient cultures across the world discovered and studied psilocybin-containing mushrooms, citing a prehistoric cave drawing of a shaman figure clutching mushrooms found in the Tassili caves in the Altas Mountains. This suggests, the authors said, that psychedelic mushrooms have played an important part in the evolutionary process of humans.
