The Stoned Ape Theory, first proposed by American ethnobotanist and mystic Terence McKenna, suggests that the cognitive revolution was triggered by the addition of psilocybin mushrooms to the human diet. Psilocybin and similar psychedelics primarily target the serotonin 2A receptor subtype, stimulating an active coping strategy response that may have provided an enhanced capacity for hominins to adapt to their ever-changing environment through a flexible and associative mode of cognition. While there is no solid evidence that early hominins consumed mind-altering substances, the Stoned Ape Theory has become a staple of psychedelic culture, with advocates pointing to advancements in fields such as epigenetic inheritance and neuroplasticity that may further explain the mechanisms involved in psychedelics-assisted cognitive advancement.

Stoned Ape Theory
The Stoned Ape Theory, proposed by American ethnobotanist Terence McKenna in his 1992 book "Food of the Gods", suggests that the evolution from Homo erectus to Homo sapiens was catalysed by the consumption of psilocybin mushrooms. McKenna theorised that psilocybin mushrooms enhanced sensory perception, improved cognitive functioning, and increased activity in the "language-forming region of the brain". He also believed that the mushrooms promoted greater social bonding within early human communities, leading to group sex activities and increased genetic diversity.
McKenna's theory has been widely criticised by the scientific community as being overly speculative and based on a misrepresentation of existing research. However, it has gained traction in psychedelic culture and among some advocates of modern psychedelic reconnection. Mycologist Paul Stamets, for example, points to advancements in fields such as epigenetic inheritance and neuroplasticity that may help explain the mechanisms by which psychedelics could have influenced cognitive advancement.
The Stoned Ape Theory is not without its evidentiary support. Current understandings of early hominins' paleodiets and paleoecology, primate phylogeny, and the biogeography of psilocybin-containing fungi indicate that hominins likely ingested psychedelic mushrooms throughout their evolutionary history. This consumption may have begun as early as the Pliocene, approximately 5.3 million years ago, when semi-arboreal hominins increased their foraging activity on the forest floor.
The psychotropic tryptamines psilocybin and psilocin are known to induce altered states of awareness, commonly referred to as the psychedelic experience. When ingested, psilocybin targets the serotonin 2A receptor subtype, stimulating an active coping strategy response. This response may enhance the capacity for adaptive changes through a flexible and associative mode of cognition. Psilocybin also alters emotional processing, self-regulation, and social behaviour, often having enduring effects on individual and group well-being.
In conclusion, while the Stoned Ape Theory has been criticised for its speculative nature, there is evidence to suggest that the consumption of psilocybin mushrooms may have played a role in human evolution by enhancing cognitive functioning, social bonding, and adaptability. However, as Dennis, one of the theory's critics, points out, there were undoubtedly multiple factors involved in human evolution, and it would be simplistic to attribute it solely to mushroom consumption.

Psilocybin Mushrooms as Evolutionary Catalyst
Psilocybin mushrooms, also known as magic mushrooms, have been theorized to play a significant role in human evolution. This idea, known as the "stoned ape theory," was first proposed by American ethnobotanist and mystic Terence McKenna in his 1992 book, "Food of the Gods." According to McKenna, the inclusion of psilocybin mushrooms in the human diet around 100,000 years ago sparked the cognitive revolution, leading to the emergence of language, self-reflection, imagination, art, religion, philosophy, science, and all of human culture.
While the stoned ape theory has been widely criticized by the scientific community for its speculative nature and lack of solid evidence, it has gained traction in psychedelic culture. Proponents of the theory argue that the psychotropic effects of psilocybin, such as altered states of awareness and enhanced neural plasticity, may have contributed to the development of advanced cognitive abilities in early hominins. They also point to archaeological evidence suggesting that prehistoric humans consumed mushrooms and that various types of fungi were a significant part of their diet.
Furthermore, the theory of psychedelic instrumentalization suggests that the incidental inclusion of psychedelics in the diet of hominins and their integration into rituals and institutions of early humans may have conferred selective advantages. Psilocybin's ability to modulate the 5-HT2A receptor-mediated active coping strategy may have enhanced cortical plasticity, associative learning, and the capacity for psychological transformation. This could have increased early hominins' adaptability and fitness in an ever-changing environmental landscape, contributing to their survival and evolutionary success.
Additionally, the utilization of psilocybin mushrooms or other psychedelic plants is documented in ethnographic and historical literature from various cultural regions, indicating their ritual use for millennia. Evidence also suggests that hominin evolution occurred in a dynamic environmental landscape, driving the advancement into a socio-cognitive niche. Psilocybin's effects on enhancing sociality, imagination, and suggestibility may have played a role in this transition, facilitating cooperative communication and social learning crucial for survival.
In conclusion, while the stoned ape theory remains speculative, the potential impact of psilocybin mushrooms on human evolution cannot be overlooked entirely. These mushrooms may have influenced the development of human culture, cognition, and societal advancements. Further research and understanding of psychedelic-assisted cognitive advancement are needed to fully comprehend the role of psilocybin mushrooms in human evolutionary history.

Incidental Ingestion of Psychedelic Mushrooms
The Stoned Ape Theory, which suggests that the consumption of psychedelic mushrooms contributed to human evolution, has gained popularity in psychedelic culture. However, it is not widely accepted in academic circles due to the complex nature of the emergence of consciousness and the potential of psychedelic compounds, which are subjects of ongoing exploration.
While the theory may not stand as the sole factor in human evolution, it is supported by evidence from various fields, including the study of early hominins' paleodiet and paleoecology, primate phylogeny, and the biogeography of psilocybin-containing fungi. Psilocybin mushrooms, or magic mushrooms, are naturally occurring and have been consumed for their hallucinogenic effects, altering thinking, emotions, and senses of time and reality.
The incidental ingestion of psychedelic mushrooms by our hominin ancestors is likely. This assertion is supported by the understanding that early hominins were omnivores that relied on forest floor foods, including mushrooms. The presence of mycophagy and self-medication among primates and Paleolithic humans suggests that hominins also incorporated bioactive fungi into their diet.
The inclusion of psychedelic mushrooms in the diet of hominins may have provided selective advantages and contributed to their advancement into a socio-cognitive niche. Psilocybin, the active compound in psychedelic mushrooms, targets the serotonin 2A receptor subtype, stimulating an active coping strategy response. This response may have enhanced hominins' capacity for adaptive changes through flexible and associative cognition, improved sociality, imagination, and suggestibility, and altered emotional processing and self-regulation. These effects could have increased hominins' overall adaptability and fitness in an ever-changing environmental landscape.
Eventually, the consumption of psychedelic mushrooms became institutionalized in many pre-modern human societies and was incorporated into rituals and institutions. While the Stoned Ape Theory may not be the sole explanation for human evolution, it highlights the potential role of psychedelic mushrooms in shaping human consciousness, cognition, and social behavior throughout our evolutionary history.

The "stoned ape" theory, which suggests that the consumption of psychedelic mushrooms contributed to human evolution, has gained traction in psychedelic culture. However, it is not widely accepted in academic circles as it involves complex factors such as the emergence of consciousness and the potential of psychedelic compounds. While it may not be the sole factor, it could have influenced certain aspects of human evolution.
Psychedelic mushrooms, specifically the psychotropic tryptamines psilocybin and psilocin, have been proposed to impact altered states of awareness and cognitive advancement. Evidence suggests that early hominins incorporated mushrooms, including bioactive species, into their diet since the Pliocene. This is supported by the study of early hominins' paleodiets, paleoecology, and primate phylogeny.
The incidental ingestion of psilocybin-containing mushrooms may have provided adaptive advantages to hominins. Psilocybin's ability to target the serotonin 2A receptor subtype stimulates an active coping strategy response, enhancing cognitive flexibility and associative learning. This could have improved hominins' ability to adapt to changing environments and influenced the development of social behaviours, emotional processing, and self-regulation.
The inclusion of psychedelics in the diet and rituals of early humans may have contributed to selective advantages and the creation of a socio-cognitive niche. Psychedelics' effects on sociality, imagination, and suggestibility may have increased the adaptability and fitness of early human societies. However, it is important to note that the impact of psychedelic mushrooms on human evolution is a subject of ongoing research and exploration.
Regarding the evolution of human hepatic enzymes, liver enzymes are proteins that play a crucial role in various chemical reactions in the body, including the liver. Elevated levels of liver enzymes in the blood, such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), can indicate liver damage or injury. These enzymes are commonly associated with conditions like hepatitis, liver disease, and fatty liver disease, which can be caused by factors such as viral infections, alcohol consumption, and certain medications. While elevated liver enzymes may be temporary, they can also signify underlying medical conditions that require further investigation and treatment.

Therapeutic Uses of Psychedelics
The use of psychedelics has a long and complex history, with evidence suggesting that our hominin ancestors ingested psychedelic mushrooms throughout their evolutionary journey. This idea, known as the "stoned ape theory," proposes that the consumption of psilocybin mushrooms influenced human consciousness, cognition, and societal development. While this theory has gained traction in psychedelic culture, it remains a challenging concept to study scientifically. Nonetheless, the potential therapeutic uses of psychedelics are being explored in modern times.
Psychedelic substances, including psilocybin (magic mushrooms), DMT, peyote, ayahuasca, ibogaine, ketamine, MDMA, and LSD, have been the subject of renewed interest in clinical research settings worldwide. These substances, once classified as "drugs of abuse," are now being investigated for their therapeutic potential in treating various mental health conditions. Indigenous communities have long used psychedelics in therapeutic and religious contexts, and Western clinical settings are beginning to explore their benefits in what is known as psychedelic therapy.
Psychedelics have shown promising results in the treatment of several mental health disorders. For example, in individuals with severe PTSD, psilocybin has been found to be effective, with 67% of participants in one study no longer meeting the criteria for a PTSD diagnosis after three treatments. Psilocybin has also demonstrated positive outcomes in treating depression and anxiety in people with terminal illnesses. Additionally, it is believed that psilocybin could be beneficial in treating obsessive-compulsive disorder, addiction, and treatment-resistant depression.
LSD, a potent and long-lasting psychedelic, is considered the prototype for therapeutic psychedelics. It has been shown to aid in the treatment of anxiety, depression, and end-of-life distress. MDMA, another psychedelic substance, has been found to be effective in treating post-traumatic stress disorder (PTSD) when used in conjunction with psychotherapy. This combination has resulted in significant reductions in PTSD symptom severity and improvements in emotional processing and social behaviour.
While the therapeutic potential of psychedelics is promising, it is important to acknowledge the potential risks and adverse effects. The most common adverse effects from the administration of psychedelics under clinical supervision include acute increases in anxiety, fear, heart rate, and blood pressure. Delayed-onset headaches are sometimes reported with psilocybin use. Additionally, careful supervision is necessary to prevent dangerous behaviour. As research and advocacy for decriminalization continue, the understanding of the therapeutic uses of psychedelics is expected to evolve further.

They also argue that psilocybin mushrooms improved visual acuity, hunting skills, libido, attention, and energy, resulting in greater reproductive success.
The Stoned Ape Theory has been criticised by the academic community for being overly speculative and misrepresenting the studies of psychopharmacologist Roland L. Fischer, whose research was frequently cited by McKenna. Furthermore, critics point to groups such as the Aztecs or Amazonian tribes whose usage of psychedelic substances does not reflect any of the evolutionary advantages that McKenna argued would emerge from using psilocybin-containing substances.
While there is evidence that our hominin ancestors encountered and likely ingested psychedelic mushrooms throughout their evolutionary history, there is no solid evidence proving that early hominins consumed mind-altering substances. The Stoned Ape Theory remains a contentious hypothesis and the truth about whether early hominins ate magic mushrooms is uncertain.
