Positive psychology is a thriving field with increasing political influence, yet there are few evolutionary studies that have had a tangible impact on rethinking mechanisms of well-being. This Element reviews existing literature and proposes synthesizing insights into human flourishing under an umbrella of multilevel selection (MLS). Conceptualizing quality of life as 'Happiness + Meaning = Well-being' draws attention to how people navigate between individual and group needs, and how they reconcile selfish pursuits with altruism and cooperation. We define happiness (...) as the cluster of affects that reward individuals for solving adaptive challenges. We approach meaning as a reward that individuals experience when contributing to their community. By way of examples, we critically examine the Nordic well-being societies whose ethos and education advance prosocial values and practices and strike a balance between individualist and communitarian ideals. This title is also available as Open Access on Cambridge Core. (shrink)

Recent work in biology, cognitive psychology, and archaeology has renewed evolutionary perspectives on the role of natural selection in the emergence and recurrent forms of religious thought and behavior, i.e., mental representations of supernatural agents, as well as artifacts, ritual practices, moral systems, ethnic markers, and specific experiences associated with these representations. One perspective, inspired from behavioral ecology, attempts to measure the fitness effects of religious practices. Another set of models, representative of evolutionary psychology, explain religious thought (...) and behavior as the output of cognitive systems (e.g., animacy detection, social cognition, precautionary reasoning) that are not exclusive to the religious domain. In both perpectives, the question remains open, whether religious thought and behavior constitute an adaptation or a by-product of adaptive cognitive function. (shrink)

In recent decades it has become increasingly clear that a substantial amount of cognitive work goes on independent of consciousness. The research has been carried out largely under two rubrics, implicit learning and implicit memory. The former has been concerned primarily with the acquisition of knowledge independent of awareness and the latter with the manner in which memories not readily available to conscious recall or recognition play a role in behavior; collectively these operations comprise the essential functions of the cognitive (...) unconscious. This paper reviews the recent history of work on these issues, identifies some of the problems confronting researchers, and introduces a theoretical framework based on principles of evolutionary biology within which to view them. The argument is that the cognitive unconscious, despite its apparent sophistication, is of considerable evolutionary antiquity and antedates conscious cognitive systems by a considerable amount of time. Various entailments of this evolutionary perspective are explored including such issues as phylogeny and ontogeny of implicit processes, the robustness of the implicit functions as displayed by the capacity to resist disruptions from psychological and neurological disorders, the relationship between implicit cognition and intelligence, and individual differences in implicit cognitive abilities.

The papers in this volume present varying approaches to human aggression, each from an evolutionary perspective. The evolutionary studies of aggression collected here all pursue aspects of patterns of response to environmental circumstances and consider explicitly how those circumstances shape the costs and benefits of behaving aggressively. All the authors understand various aspects of aggression as evolved adaptations but none believe that this implies we are doomed to continued violence, but rather that variation in aggression has (...) class='Hi'>evolutionary roots. These papers reveal several similarities between human and nonhuman aggression, including our response to physical strength as an indicator of fighting ability, testosterone response to competition, a sensitivity to paternity, and baseline features of intergroup aggression in foragers and chimps. There is also one paper tackling the phylogeny of these traits. The many differences between human and nonhuman aggression are also pursued here. Topics here include the impact of modern weapons and extremes of wealth and power on both the costs and benefits of fighting, and the scale to which coercion can promote aggression that acts against a fighter’s own interests. Also the implications of large-scale human sociality are discussed. (shrink)

There is an active research program currently underway, which treats cancer progression as an evolutionary process. This contribution investigates the ways that cancer progression is like and unlike evolution in other contexts. The aim is to take a multi-level perspective on cancer, investigating the levels at which selection may be acting, the unit or target of selection, the relative roles of selection and drift, and the idea that cancer progression may be a by-product of selection at other levels (...) of organization.

Utilizing an evolutionary perspective has proven fruitful in a number of areas of interest outside of the standard psychological or anthropological topics. This includes a wide range of fields from applied disciplines such as law, criminology, medicine, and marketing, to the study of the imagined worlds found in art and literature, the domains of the humanities. A number of excellent books, as well as numerous articles, detail the impressive work done in applying evolutionary insights to the study (...) of art and literature. This article focuses on evolutionarily informed explorations of popular culture, an area that, only relatively recently, has benefited from research taking this approach. The existing scholarship in this area will be reviewed, and future directions and challenges highlighted. (shrink)

Many studies show that punishment, although able to stabilize cooperation at high levels, destroys gains which makes it less efficient than alternatives with no punishment. Standard public goods games (PGGs) in fact show exactly these patterns. However, both evolutionary theory and real world institutions give reason to expect institutions with punishment to be more efficient, particularly in the long run. Long-term cooperative partnerships with punishment threats for non-cooperation should outperform defection prone non-punishing ones. This article demonstrates that fieldwork data (...) from hunter-gatherers, common pool resource management cases and even PGGs support this hypothesis. Although earnings in PGGs with a punishment option may be lower at the beginning, efficiency increases dramatically over time. Most ten-period PGGs cannot capture this change because their time horizon is too short. (shrink)

Coall & Hertwig (C&H) bring attention to alternative accounts of grandparental investment from economics, evolutionary anthropology, psychology, and sociology, which have yet to be reconciled. We attempt to help integrate some of the disparate perspectives by expanding the scope of the evolutionary perspective, highlighting some gaps, and discussing problems with the authors' treatment of grandparents in traditional societies.

The scientific study of atheism and unbelief is at a pivotal turning point: past research is being evaluated, and new directions for research are being paved. Organizations are being formed with an exclusive focus on unbelief research, and large grants are funding the topic in ways that historically have never happened before. This article serves as an introduction to the state of the literature and study of evolutionary perspectives towards unbelief, which incorporates cognitive, adaptive, and biological contributors. This article (...) serves to contextualize the subsequent articles, which all have distinct perspectives on the evolutionary factors that contribute towards unbelief. (shrink)

Humans are one of the most cooperative and altruistic species on the planet. At the same time, humans have a long history of violent and deadly intergroup conflicts, i.e. wars. Recently, contemporary evolutionary theorists have revived Charles Darwin’s idea that human in-group altruism and out-group hostility might have co-evolved. Groups with more cooperatively aggressive men, they suggest, were more likely to prevail in the frequent lethal quarrels of human pre-history, and these men, therefore, more likely to have passed on (...) their genes. After a short introduction to evolutionary perspectives on war heroism, we describe selected characteristics of 988 modern war heroes, the US-American Medal of Honor recipients of WWI, WWII, the Korean and the Vietnam War, and discuss whether an evolutionary perspective can help us understand why these men risked their lives ‘beyond the call of duty’.

The purpose of this article is to present a model of well-being based on current research in neurobiology and psychology, integrated in an evolutionary perspective of the human mind. Briefly, the primary purpose of nervous systems is to direct an animal toward behavior should be conducive to survival and procreation, and as a rule of thumb this implies either approach or avoidance. While behavior originally was based on reflexes, in humans the brain contains a system of negative and (...) positive affect. Although an array of functions has evolved that employ emotions in order to handle various pursuits, recent studies suggest that they converge on shared neural circuits involved in mood, that is, they converge on circuits designed to generate reward and punishment. Happiness can be construed as the net output of these brain modules. Neural circuits tend to gain in strength and influence upon frequent activation, which suggests a strategy for improving happiness and mental health: to avoid excessive stimulation of negative modules, to use cognitive interference to enhance the "turn off" function of these modules, and to exercise modules involved in positive feelings.

Pregnancy is thought to be a metabolically very expensive endeavor, yet investigations have produced inconsistent results concerning the responsiveness of human birth weight to maternal nutritional stress or nutritional intervention. These findings have led some researchers to conclude that fetal growth is strongly buffered against fluctuations in maternal energy balance, making the fetus in effect a “nearly perfect parasite.” This buffering would appear to be a reasonable adaptive response given the high risk of morbidity and mortality associated with low birth (...) weight. However, a life-history approach leads to the prediction that maternal investment strategies in pregnancy should be geared toward maximizing lifetime reproductive success rather than simply the success of the current pregnancy, and by extension that maternal investment strategies should vary with reproductive value. The physiology of human pregnancy in fact appears to include a number of mechanisms that protect maternal energy resources from diversion to the fetus and preserve them for future reproductive events. These mechanisms include adjustment of blood flow to the uterus and perhaps minor adjustments in gestation length, although evidence for the latter is scant. Suggestions are made for ways of investigating these maternal options. (shrink)

This book asks whether evolution can help us to understand human behaviour and explores diverse evolutionary methods and arguments. It provides a short, readable introduction to the science behind the works of Dawkins, Dennett, Wilson and Pinker. It is widely used in undergraduate courses around the world.

Evolution fuels interindividual variability in neuroplasticity, reflected in brain anatomy and functional connectivity of the expanding neocortical regions subserving reading ability. Such variability is orchestrated by an evolutionarily conserved, competitive balance between epigenetic, stress-induced, and cognitive-growth gene expression programs. An evolutionary developmental model of dyslexia, suggests that prenatal and childhood subclinical stress becomes a risk factor for dyslexia when physiological adaptations to stress promoting adaptive fitness, may attenuate neuroplasticity in the brain regions recruited for reading. Stress has the potential (...) to blunt the cognitive-growth functions of the predominantly right hemisphere Ventral and Dorsal attention networks, which are primed with high entropic levels of synaptic plasticity, and are critical for acquiring beginning reading skills. The attentional networks, in collaboration with the stress-responsive Default Mode network, modulate the entrainment and processing of the low frequency auditory oscillations and visuospatial orienting linked etiologically to dyslexia. Thus, dyslexia may result from positive, but costly adaptations to stress system dysregulation: protective measures that reset the stress/growth balance of processing to favor the Default Mode network, compromising development of the attentional networks. Such a normal-variability conceptualization of dyslexia is at odds with the frequent assumption that dyslexia results from a neurological abnormality. To put the normal-variability model in the broader perspective of the state of the field, a traditional evolutionary account of dyslexia is presented to stimulate discussion of the scientific merits of the two approaches.

Evolutionary Psychology links the methodology for cognitive science associated with the late David Marr to evolutionary theory. The mind is conceived as a bundle of modules which can be described at three theoretical levels. Each module represents an adaptation to some specific ecological problem. Evolutionary psychologists try to derive the highest level of description using a heuristic method called 'adaptive thinking'. This paper questions the value of the official EP methodology and reasserts the value of the earlier (...) methodology associated with classical ethology, in which the structural and comparative analysis of the products of evolution precedes the investigation of their origin by natural selection. The adaptive heuristic is shown to be unhelpful. It tends to restrict psychology to work designed to confirm our preconceptions. It is argued that evolutionary psychology must be retrodictive and explanatory, rather than predictive, and that a powerful method for testing postulated claims about the adaptive origin of traits is available in modern versions of the comparative method. Some arguments for the inapplicability of the comparative method to human psychoevolution are examined and shown to be specious. These various points are exemplified in evolutionary work on emotions.

Hebbian mechanisms are justified according to their functional utility in an evolutionary sense. The selective advantage of correlating content-contingent stimuli reflects the putative common cause of temporally or spatially contiguous inputs. The selective consequences of such correlations are discussed by using examples from the evolution of signal form in sexual selection and model-mimic coevolution. We suggest that evolutionary justification might be considered in addition to neurophysiology plansibility when constructing representational models.

Busca-se acompanhar o desenvolvimento da teoria evolucionária no pensamento de Habermas, a partir da afirmação colhida no prólogo de Problemas de Legitimação do Capitalismo Tardio, de 1973: "O caráter programático evidencia que uma teoria da evolução social hoje se encontra apenas esboçada, mas que, no entanto, deveria constituir a base da teoria da sociedade". A atenção é direcionada à forma como Habermas reorienta o sentido evolucionário do desdobramento histórico à luz do conceito de mundo da vida, como esfera de realização (...) da ação comunicativa. Objetiva-se investigar como é projetada nesse modelo de ação, por meio da linguagem, a tarefa de produção e reprodução simbólica do consenso normativo entre os participantes do mundo social, ao mesmo tempo em que Habermas sinaliza haver um telos de integração social imanente à própria prática comunicativa. Nesse sentido, procurar-se-á demonstrar que, assim como a pragmática universal serve de base teórica para a análise de processos de distorção da linguagem e de socialização anormais, a teoria da evolução social serve de parâmetro para uma teoria social crítica com intenção emancipatória de avaliar o desdobramento empírico e contingente da dinâmica histórica. We seek to follow the development of evolutionary theory in the thought of Habermas, starting with the statement taken from the Prologue of Legitimation Crisis, 1973: "The programmatic character of Part I of this book makes clear that a theory of social evolution, although it must be the basis of social theory, is today still scarcely at all developed." Attention is directed to how Habermas reorients the evolutionary meaning of historical development in light of the concept of lifeworld as the sphere of the realization of communicative action. We seek to investigate how Habermas' model assigns, by means of language, the task of symbolic production and reproduction of the normative consensus among participants in the social world, while at the same time indicating that there is a telos of social integration immanent in the communicative practice itself. In this sense, we seek to demonstrate that just as universal pragmatics serves as the theoretical basis for the analysis of processes of abnormal socialization and the distortion of language, the theory of social evolution serves as a parameter for a critical social theory with the emancipatory intent of evaluating the empirical and contingent unfolding of historical dynamics.

Behavioral ecologists often assume that natural selection will produce organisms that make optimal decisions. In the context of information processing, this means that the behavior of animals will be consistent with models from fields such as signal detection theory and Bayesian decision theory. We discuss work that applies such models to animal behavior and use the case of Bayesian updating to make the distinction between a description of behavior at the level of optimal decisions and a mechanistic account of how (...) decisions are made. The idea of ecological rationality is that natural selection shapes an animal's decision mechanisms to suit its environment. As a result, decision-making mechanisms may not perform well outside the context in which they evolved. Although the assumption of ecological rationality is plausible, we argue that the exact nature of the relationship between ecology and cognitive mechanism may not be obvious. (shrink)

Most people are aware of the health benefits of being physically active. The question arises then why people so easily fall into sedentary habits. The idea developed here is that sedentary behavior is part of a suite of behaviors to reduce levels of physical activity that were strongly selected in the evolutionary past, likely because high levels of physical activity had direct negative consequences for survival. However, hunter‐gatherer populations could not reduce activity indefinitely because of the need to be (...) active to hunt for, and gather food. Hence they never experienced low levels of activity that are damaging to health, and no corresponding mechanism avoiding low activity evolved. Consequently, gene variants promoting efficiency of activity and increased sedentariness were never selected against. Modern society facilitates reduced activity by providing many options to become less active and divorcing food intake from the need to be active. Choosing the less active option is hard wired in the genes; this explains why being sedentary is so common, and why reversing it is so difficult. Incentivizing activity may be enabled using modern technology, but ultimately may only end up replacing one set of health issues with others.

Crespi & Badcock (C&B) have presented a novel view that the influence of genomic imprinting causes diametrically opposite disorders: namely, psychoses and autism. I propose an extended hypothesis that while genomic imprinting is likely to have an influence on the pathogenesis of psychoses and autism, it might contribute to phenomenological antithesis between as well as within these disorders.

Humans are expert users of metarepresentations. How has this human metarepresentational capacity evolved? In order to contribute to the ongoing debate on this question, the chapter focuses on three more specific issues: i. How do humans metarepresent representations? ii. What came first: language, or metarepresentations? iii. Do humans have more than one metarepresentational ability?

Human cultural life is replete with examples of adaptations to the social, physical, and biological environments that have been built gradually, cumulatively, by hidden-hand mechanisms. The impressive technologies, natural history databases, and exchange networks of traditional peoples have been built in this way. But the ethnological record is also replete with evidence of maladaptive beliefs and practices, and of failures to adapt to changing circumstances. This paper is about such failures. In what ways is cultural evolution constrained, and what explains (...) those constraints? In what ways are those constraints similar to those that affect gene-based evolution; in what ways are they different? In this paper I argue that there are some similar mechanisms of constraint ; there are some differences ; but the major difference results from a division of labor between inheritance systems; the problem of fast change has been offloaded from the genetic to the cultural system.

Exploitation is a fundamental element of the parental strategies of many species of birds. Cuckoos, for example, lay their eggs in the nest of other birds, who often unwittingly rear the alien nestlings as their own. Nest parasitism is an efficient reproductive strategy for cuckoos, who do not have to worry about building a nest, incubating their eggs, or feeding their nestlings. But not all hosts respond passively to such intrusions. In response to parasitic cowbirds, for example, robins have evolved (...) the ability to detect and selectively eject alien young from their nests. Human parenting strategies differ sharply from the strategies of cuckoos and robins. Unlike cuckoos, we are reluctant to allow our children to be raised by others. Unlike robins, we knowingly rear strange young. What makes human behavior toward children so different from that of cuckoos and robins? Humans seem to share a number of predispositions that facilitate successful adoptive relationships, and the desire to raise children seems to be pervasive among modern humans. Despite these commonalities, patterns of adoption transactions vary greatly among contemporary human societies. This paper considers the origins and causes of cross-cultural variation in human adoptive behavior from an evolutionary perspective. (shrink)

Work was conducted among traditional, subsistence whale hunters in Lamalera, Indonesia, in order to test if strict biological kinship or lineage membership is more important for explaining the organization of cooperative hunting parties ranging in size from 8 to 14 men. Crew identifications were collected for all 853 hunts that occurred between May 3 and August 5, 1999. Lineage identity and genetic relatedness were determined for a sample of 189 hunters. Results of matrix regression show that genetic kinship explains little (...) of the hunters’ affiliations independent of lineage identity. Crew members are much more closely related to each other than expected by chance, but this is due to the correlation between lineage membership and genetic kinship. Lineage members are much more likely to affiliate in crews, but kin with r<0.5 are just as likely not to affiliate. The results are discussed vis-à-vis the evolution of cooperation and group identity. (shrink)

Defenders of evolutionary medicine claim that medical professionals and public health officials would do well to consider the role of evolutionary biology with respect to the teaching, research, and judgments pertaining to medical theory and practice. An integral part of their argument is that the human body should be understood as a bundle of evolutionary compromises. Such an appreciation, which includes a proper understanding of biological function and physiological homeostasis, would provide a crucial perspective regarding the (...) understanding and securing of human health needs currently lacking in the medical arena.

Law and Evil presents an alternative evolutionary picture of man, focusing on the origins and nature of human evil, and demonstrating its useful application in legal-philosophical analyses. Using this representation of human nature, Wojciech Załuski analyses the development of law, which he interprets as moving from evolutionary ethics to genuine ethics, as well as arguing in favour of metaethical realism and ius naturale.

The notion of development has been permeated by concepts and methods from positivistic science. As a result, many development initiatives are reductionistic, myopic, and with little or impact on the improvement of the quality of life and the sustainability of communities and societies. This article marks the beginning of a transdisciplinary inquiry among the authors, motivated by direct interest in the issue of development, per se, and in particular, Mexico's development. Our inquiry departs from and weaves together our various areas (...) of expertise and experience, including: systems theory, general evolution theory, economic development, technology transfer, social innovation, sustainable development, environmental behavior, social systems design, and education. The article reviews the concept of development from an evolutionary and systemic perspective. It outlines the foundations of evolutionary development in terms of theory, philosophy, and methodology and provides a conceptual framework for future research aimed at the articulation of a practical model for evolutionary development.

In 1923, Sir Arthur Keith proposed that many common back problems are due to the stresses caused by our evolutionarily novel form of locomotion, bipedalism. In this article, we introduce an updated version of Keith’s hypothesis with a focus on acquired spinal conditions. We begin by outlining the main ways in which the human spine differs from those of our closest living relatives, the great apes. We then review evidence suggesting there is a link between spinal and vertebral shape on (...) the one hand and acquired spinal conditions on the other. Next, we discuss recent studies that not only indicate that two common acquired spinal conditions—intervertebral disc herniation and spondylolysis—are associated with vertebral shape, but also suggest that the pathology-prone vertebral shapes can be understood in terms of the shift from quadrupedalism to bipedalism in the course of human evolution. Subsequently, we place the aforementioned findings under an umbrella hypothesis, which we call the “Evolutionary Shape Hypothesis.” This hypothesis contends that individuals differ in their propensity to develop different acquired spinal conditions because of differences in vertebral shape that relate to the evolutionary history of our species. We end the article with some possible directions for future research. (shrink)
