1016/B978-0-12-397025-1. Moreover, this "pivotal mental state" (Brouwer and Carhart-Harris, 2021) involves a generalized malleability, in the form of enhanced synaptogenesis and neural plasticity (Ly et al., 2018), as well as low-level learning and extinction learning (Carhart-Harris and Nutt, 2017) that can further aid self-actualization and self-editing. The robust dishabituating effects of psychedelics on behavior and their persistent rhetorical features (glossolalia and graphomania) that make discourse more attention-grabbing (Doyle, 2011) provided credible costly signals of purported direct interaction with superhuman agents, a persuasive demonstration that the diviners were not the authors of the statements they uttered. Therefore, the answer to this question also resides in the specifics of the human lifeway, which placed a premium on social tolerance and cognitive flexibility (both regulated by 5-HT; Tricklebank and Daly, 2019) making the ingestion of 5-HT-mimicking psychedelics potentially beneficial and adaptive. Entry into the socio-cognitive niche involved increasing cognition, sociality, communication, and social learning. Many shamanistic healing traditions use psychedelics to facilitate an experience of contact between the ritual specialist and supernatural beings/realms, inducing visions that provide knowledge about the causes of the condition afflicting the patient and proper treatment, or allowing healers to confront and combat a disease through symbolic battles with its cause (Rivier and Lindgren, 1972; Harner, 1973; Dobkin de Ríos, 1984; Ferreira Júnior et al., 2015). Raghanti, M. A., Edler, M. K., Stephenson, A. R., Munger, E. L., Jacobs, B., Hof, P. R., et al. 1016/s0091-3057(01)00670-0. Solved] Inventory records for Dunbar Incorporated revealed the following:... | Course Hero. Psychedelics can afford genuine epistemic benefits even if there is no transcendent reality or all-knowing otherworldly agents (Winkelman, 2013b; Letheby, 2019). Psychedelics' capacity to engender convincing experiences of travel to alternative worlds involving communication with autonomous entities (Winkelman, 2018; Luke, 2020) – apparently allowing a ritual specialist to channel those agents' knowledge – likely made its ingestion a seemingly reliable procedure for obtaining inscrutable information. Recent studies show that psychedelics can modify a range of social behaviors and cognitive processes, having pro-social effects (Table 2; also see Preller and Vollenweider (2019) for a recent review of experimental and controlled studies in humans). Our extensive online study community is made up of college and high school students, teachers, professors, parents and subject enthusiasts who contribute to our vast collection of study resources: textbook solutions, study guides, practice tests, practice problems, lecture notes, equation sheets and more.
Given that the socio-cognitive niche: (a) is simultaneously selection pressure and adaptive response (Downey and Lende, 2012); and (b) was partially constructed by hominins through their metabolism, their activities, and their choices (Laland et al., 2016), a second key aspect of this model is that psychedelic instrumentalization had niche-constructing effects that concomitantly aided in the creation and evolution of the socio-cognitive niche (right side of Figure 1). 5 mya) are implied by their presence in African grasslands (Guzmán et al., 2014), especially growing on dung of ungulates [an important target of hominin scavenging and hunting for millions of years (Domínguez-Rodrigo and Pickering, 2003)]. An important matter that remains to be properly addressed concerns the question of why psychedelics affect our minds in the way they do. This novel form of socially infused thinking (Tomasello, 2014) entails unique cognitive skills and motivations for collaborating and communicating with others, such as an altruistic and egalitarian orientation and the capacity to mindread in order to enhance interpersonal coordination (Bernhard et al., 2006; Fehr et al., 2008; Heyes and Frith, 2014).

Eventually, psychedelic consumption was institutionalized in many pre-modern human societies in ritual activities focused on healing, divination (i. e., for obtaining otherwise inaccessible information), and socialization (e. g., in initiations) (Dobkin de Ríos, 1984; Furst, 1990; Schultes et al., 2001; Rätsch, 2005; Quirce et al., 2010; Leptourgos et al., 2020).

Samorini, G. "Mushroom effigies in archaeology: a methodological approach, " in Fly Agaric. We suggest under these conditions of disease and stress, psychedelic use could have improved stress management, healing, and well-being. Current Topics in Behavioral Neurosciences, Vol. Dynamical exploration of the repertoire of brain networks at rest is modulated by psilocybin.
As will be shown below, the likelihood of intentional and repeated use of psilocybin is supported by its low toxicity and by its close resemblance to the neurotransmitter serotonin, which opened up the possibility for its exploitation as a "treatment" for a significant homeostatic challenge recurrent in a socio-cognitive niche – serotonin depletion. What is the cost of goods sold for Julia & Company assuming it uses LIFO? Thus, while psychedelics may have entered hominin evolution via their role as a "treatment" for 5-HT depletion, once full "migration" into a socio-cognitive niche was complete (which involved establishment of a foraging strategy extended to large mammalian prey) their ingestion was likely sustained because of the additional adaptive benefits their ritual and symbolic instrumentalization could confer to humans properly (see below). Inventory records for dunbar incorporated revealed the following activities. Other sets by this creator.
Concomitantly, the concern for self-reputation as a cooperator would have likely disincentivized free-riding or cheating strategies from psychedelic-using shamans since anyone with a poor reputation would have been avoided in the first place. Our ancestors integrated these diverse semiotic elements in their collaborative efforts to interact with, and modify, their local physical and social ecologies, producing alterations in those ecologies that created new potentials for evolutionary dynamics (Fuentes, 2015). Ancient Hominin Diets and the Ecology of Psilocybin-Containing Fungi. Psilocybin thus stimulates a system that evolved to mediate rapid and deep learning when faced with environmental demands for change (Brouwer and Carhart-Harris, 2021). From a homeostatic perspective, increased fitness can potentially result from consumption of psychoactive plants containing compounds that chemically resemble endogenous signaling molecules, especially when internal signaling functions are compromised [e. g., due to deficiencies in dietary precursors in marginal environments (Sullivan and Hagen, 2015)]. We hypothesize that the presence of psychedelics in the hominin social environment had significant consequences on the selective regime that drove hominin cognitive and behavioral evolution because it facilitated the construction of the adapted social environments that in turn selected for enhancements in the same underlying human capabilities that sustained the socio-cognitive niche. Inventory records for Dunbar Incorporated revealed - Gauthmath. This degradation of the brain's ability to impose the habitual organization and categorization schemas involves a temporal disabling of the functioning of the DMN that decreases top-down inhibition and liberates bottom-up information flow to specific cortical areas, particularly via intrinsic sources such as the limbic system (Carhart-Harris and Friston, 2019; Vollenweider and Preller, 2020). 1 Evolutionary Anthropologist, Independent Researcher, San José, Costa Rica.
The role of serotonin in human mood and social interaction. Furthermore, psilocybin shifts emotional biases away from negative toward positive stimuli (Kraehenmann et al., 2016), and a single high-dose experience can engender measurable and long-lasting changes in socially oriented aspects of personality, such as increases in the dimensions of Openness and Extraversion (MacLean et al., 2011; Bouso et al., 2018; Erritzoe et al., 2018). Psychedelic Sociality: Pharmacological and Extrapharmacological Perspectives. The various aspects of social cognition and behavior of the cognitive niche are dynamic components that established reinforcing relationships among themselves (e. g., mindreading and culture create, and in turn, are sustained through sociality), embodying an interconnected, adaptive complex that sustains our unique survival mode (Whiten and Erdal, 2012). The utilization of psilocybin mushrooms or other psychedelic plants is documented in the ethnographic and historical literature from all cultural regions of the globe except the Insular Pacific (see Table 1 for examples). Primates solve this problem by developing intense forms of commitment to each other through close physical proximity and the use of touch (e. g., licking and other social grooming behaviors [Dunbar, 2010]). Inventory records for dunbar incorporated revealed the following services. Psychopharmacology (Berl) 233, 3395–3403. The suggestion put forward is that psychedelics supported the elaboration of socially constructed environments – involving collective rituals, synchronic activities, and guidance by prosocial leaders – that could persist even if psychedelic instrumentalization was no longer an active part of the hominin behavioral repertoire. The socio-cognitive niche was simultaneously a selection pressure and an adaptive response, and was partially constructed by hominins through their activities and their choices. Therefore, as has been cogently argued by Boyd et al. It also emphasizes the interactions between genetic and cultural processes over evolutionary time (Richerson et al., 2010). Sayers, K., and Lovejoy, C. O. This suggests that psychedelics increased social tolerance and cohesion by inducing socially desirable mood changes from reduced neural responses to negative stimuli (Kometer et al., 2012; Mueller et al., 2017; Barrett et al., 2020; Vollenweider and Preller, 2020). Considering the costly nature of 5-HT production, its key role in hominin adaptive brain function and behavior, and the increasing selection pressures for sophisticated social cognition skills for participation in the socio-cognitive niche, it is reasonable – perhaps inevitable – that early hominins actively pursued available exogenous chemical analogs of 5-HT.
This alteration of distributed neural processes manifests as increased synaptic plasticity and entropy, as well as reduced integrity of discrete brain networks (e. g., functional disintegration of the default-mode network [DMN]) and reduced segregation between networks (e. g., increased functional connectivity between the DMN and dorsal attention network) (De Gregorio et al., 2018; Preller et al., 2019, 2020; Madsen et al., 2021). The ontologically shocking effects of psychedelics and their meaning-enhancing properties is likely why their use commonly occurs in engineered social contexts (e. g., in intense and immersive shared experiences consisting of multimodal performances of music, ritual, and dance: Sterelny, 2018; Winkelman, 2021c; also see St John, 2006). Master your assignments quickly with thousands of step-by-step solutions to countless textbook questions asked and answered by our members. The cultural evolution of prosocial religions. Neuroimage 213:116726. 1177/0269881111420188. Gabay, A. S., Carhart-Harris, R. L., Mazibuko, N., Kempton, M. J., Morrison, P. D., Nutt, D. Psilocybin and MDMA reduce costly punishment in the Ultimatum Game. 2020) shamanism appears to be a distinct form of leadership that combines a strategy of inducing fear, similar to the dominance strategy, but is based on knowledge and expertise, similar to the prestige strategy. Religion comprises symbolically and emotionally laden beliefs and practices (e. g., rituals) regarding superhuman powers, and the institutions that maintain and transmit such beliefs and practices (Bulbulia et al., 2013). Madsen, M. K., Stenbæk, D. S., Arvidsson, A., Armand, S., Marstrand-Joergensen, M. R., Johansen, S. Inventory records for dunbar incorporated revealed the following costs. S., et al. This specific cost (excessively "relaxed beliefs"; see Carhart-Harris and Friston, 2019), coupled with the rapid onset of mental tolerance and lack of hedonic reward (craving or withdrawal) help explain why psychedelic use is normally episodic and not compulsive, with chronic use being relatively unusual (Nichols, 2004, 2010). Emotional arousal when watching drama increases pain threshold and social bonding.
Moreover, the integration of psilocybin into ancient diet, communal practice, and proto-religious activity could have sustained feedback loops in which increases in social cognition and symbolic behavior engendered by psychedelic use selected for yet further increases in such capacities by increasing the richness and complexity of the social and semiotic environment. 2021) lends support to this hypothesis, showing that communitas – an intense sense of togetherness and shared humanity – mediates enduring increases in psychological well-being and social connectedness following psychedelic use in ceremonial retreats. A Compendium of History, Pharmacology, Mythology, and Exploration, ed. It has been argued that human social evolution involved two key steps: first, early humans began to cooperate more and across wider interdependent networks; and second, humans became more group-minded, conforming to social norms in culturally marked groups and punishing norm-violators (Sterelny, 2007; Tomasello et al., 2012; Jensen et al., 2014). Psychedelics and the essential importance of context. Since reasoning about causally opaque events or outcomes – those lacking a known causal explanation – is a pervasive feature of human cognition (Legare and Nielsen, 2020), it seems fitting that certain individuals (particularly ritual leaders) in numerous cultures adopted psychedelics as instruments for inspiration and envisioning, since they provide a state of consciousness that can potentially facilitate creative generation addressing knowledge gaps. Volume 12 - 2021 | Psychedelics, Sociality, and Human Evolution. Villalba, J. J., and Provenza, F. Self-medication and homeostatic behavior in herbivores: learning about the benefits of nature's pharmacy.
A neurochemical hypothesis for the origin of hominids. If organisms evolve in response to selection pressures modified by their ancestors, there is feedback in the system (Odling-Smee et al., 2003). In this context, non-authoritarian, charismatic leaders such as shamans and other leaders with supernatural abilities flourished, specializing in palliating or preventing misfortune, providing prosocial services based on knowledge and expertise related to ritual and medicinal functions (Boyer, 2019; Garfield et al., 2020). Undermining the ability of dominants to exploit others helped our ancestors replace hierarchical social dominance with a more equitable sociopolitical structure based on knowledge, conflict resolution, generosity, and status leveling mechanisms (Boehm, 1993). Tishkoff, S. A., Reed, F. A., Ranciaro, A., Voight, B. F., Babbitt, C. C., Silverman, J. Convergent adaptation of human lactase persistence in Africa and Europe.
Danilo De Gregorio, Vita-Salute San Raffaele University, Italy. This research received no resources from any funding agency, commercial or not-for-profit sectors. While incontrovertible direct evidence of psychedelic mushroom ingestion by ancient humans (e. g., dental calculus containing psilocybin mushroom tissue or spores) is lacking, there is direct evidence of the ingestion of edible mushrooms (O'Regan et al., 2016) and medicinal plants (Hardy et al., 2013) derived from analysis of dental calculus recovered from remains of humans from the Upper Paleolithic. Wei, Y., de Lange, S. C., Scholtens, L. H., Watanabe, K., Ardesch, D. J., Jansen, P. Genetic mapping and evolutionary analysis of human-expanded cognitive networks.
Cell Rep. 23, 3170–3182. Subsequently, local enhancement (i. e., naïve individuals having their attention drawn to species used by others) and social learning could have played a role in spreading the behavior though the group. 1016/0006-3223(95)00418-1. Therefore, the brain displays two different serotonin-mediated responses to adversity: a default response involving a passive coping strategy (i. e., tolerating a source of stress) mediated by 5-HT1A receptor signaling; and an active coping strategy that provides an enhanced capacity for change that is mediated by 5-HT2A receptor signaling (Carhart-Harris and Nutt, 2017). This suggests psilocybin instrumentalization could have favored a dopamine-dominated striatum personality style, which is associated with enhanced sensitivity to social cues that promote social conformity, empathy, and altruism (see Raghanti et al., 2018). Once our hominin ancestors habitually foraged on the floors of forests and in meadows, especially in tropical areas, they recurrently encountered mushrooms. Psilocybin induces time-dependent changes in global functional connectivity. No use, distribution or reproduction is permitted which does not comply with these terms.
The homeostatic and drug instrumentalization perspective we have developed suggests that despite being chemical defenses designed to deter consumption (mainly by insects), psilocybin and other psychedelics were likely exploited by humans because of their chemical resemblance to endogenous signaling molecules that are fundamental but hard for the body to produce (in this case, 5-HT). As discussed above, construction of the socio-cognitive niche entailed expansion of a set of informal religious activities or "wild traditions" (sensu Boyer, 2019) involving leaders with supernatural qualities (shamans, in the broad sense; Garfield et al., 2020) that ritually induced altered states of consciousness (involving interactions with presumed superhuman powers and supernatural entities) to provide prosocial services of healing and divination (Winkelman, 2010, 2021c). Neural correlates of the DMT experience assessed with multivariate EEG. 1007/s00213-021-05817-8. So, shamans that only imposed costs (e. g., threatening to harm others) without providing benefits (e. g., healing others) could not have gained status and would have likely been deemed cheaters deserving of shunning, ostracization, or even death. Moreover, an ability to mediate and resolve conflict (i. e., social unification capacities), healing abilities, and artistic prowess are hard-to-fake, costly behaviors that are interpreted as signaling commitment to the group's well-being.
