Evolution of Human Behavior is the first text to synthesize and compare the major proposals for human behavioral evolution from an anthropological perspective. Ideal for courses in the evolution of human behavior, human evolutionary ecology, evolutionary psychology, and biological anthropology, this unique volume reviews a wide array of approaches on how and why humans evolved behaviorally.

This book highlights the recent re-emergence of Edward Westermarck's work in modern approaches to morality and altruism, examining his importance as one of the founding fathers of anthropology and as a moral relativist, who identified our moral feelings with biologically-evolved retributive emotions. Questioning the extent to which current debates on the relationship between biology and morality are similar to those in which Westermarck himself was involved, the authors ask what can be learnt from his arguments and from the criticism that (...) he encountered. Drawing on Westermarck's manuscripts and papers as well as his published work, the authors show the importance of situating debates, whether modern or classical, in their correct methodological and philosophical context. This volume is a rigorous assessment of the ways in which morality is connected with human biological nature. It plays close attention to the development of debates in this field and will appeal to scholars of sociology, anthropology and philosophy. (shrink)

Evolutionary science (ES) and contextual behavioral science (CBS) have developed largely independently during the last half century. However, the earlier histories of these two bodies of knowledge are thoroughly entwined. ES provides a unifying theoretical framework for the biological sciences, and is increasingly being applied to human-related sciences. Meanwhile, CBS is concerned with influencing human behavior in a practical sense. This groundbreaking volume seeks to integrate ES and CBS to promote real, positive change in peoples' lives. Evolution (...) and Contextual Behavioral Science offers a unique glimpse into the histories of ES and CBS, shows how they are intrinsically linked, and outlines why their integration--or, reunification--is essential. By examining these two schools of thought side by side, you'll gain an understanding of why functional and contextual approaches in CBS need to be combined with ES for both fields to advance more rapidly. Finally, rather than the sequential relationship that is typically imagined between ES and CBS, you'll discover how an integrated relationship between these two sciences will result in a better framework for understanding predicting, and influencing human behavior--back cover.

Originally published in 1967. This reprints the second edition of 1973, revised and expanded. Evolution and Human Behaviour considers man’s biological and cultural development within the framework of Darwinian evolution. Rejecting analogue models of biological evolution common in the social sciences, the author shows how the theory of biological evolution applies to the study of contemporary human behaviour.

This chapter compares the social behaviour of human hunter-gatherers with that of the better-studied chimpanzee species, Pan troglodytes, in an attempt to pinpoint the unique features of human social evolution. Although hunter-gatherers and chimpanzees living in central Africa have similar body weights, humans live at much lower population densities due to their greater dependence on predation. Human foraging parties have longer duration than those of chimpanzees, lasting hours rather than minutes, and a higher level of mutual dependence, (...) through the division of labour between men and women ; which is in turn related to pair-bonding, and meat sharing to reduce the risk of individual hunters' failure on any particular day. The band appears to be a uniquely human social unit that resolves the tension between greater dispersion and greater interdependence. (shrink)

ABSTRACTIn political science, there is a profound tension between those who argue that the prediction of human behavior is possible and those who disagree. On the one hand, experimental methods may be able to detect behavioral patterns. On the other hand, events, the evolution of institutions, and individual behavior itself may in many cases be too historically contingent to be reliably predicted. Methodological pluralism, and a greater degree of openness to mere historical understanding, would therefore seem to (...) be called for. (shrink)

The articles in this theme issue seek to understand the evolutionary bases of social learning and the consequences of cultural transmission for the evolution of human behaviour. In this introductory article, we provide a summary of these articles and a personal view of some promising lines of development suggested by the work summarized here.

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.

According to Bickerton, the behavioral sciences have failed to give an adequate account of human nature at least partly because of the conjunction and mutual reinforcement of two widespread beliefs: that language is simply a means of communication and that human intelligence is the result of the rapid growth and unusual size of human brains. Bickerton argues that each of the properties distinguishing human intelligence and consciousness from that of other animals can be shown to derive (...) straightforwardly from properties of language. In essence, language arose as a representational system, not a means of communication or a skill, and not a product of culture but an evolutionary adaptation. The author stresses the necessity of viewing intelligence in evolutionary terms, seeing it not as problem solving but as a way of maintaining homeostasis - the preservation of those conditions most favorable to an organism, the optimal achievable conditions for survival and well-being. The term protolanguage is used to describe the stringing together of symbols that prehuman hominids employed. "It did not allow them to turn today's imagination into tomorrow's fact. But it is just this power to transform imagination into fact that distinguishes human behavior from that of our ancestral species, and indeed from that of all other species. It is exactly what enables us to change our behavior, or invent vast ranges of new behavior, practically overnight, with no concomitant genetic changes." Language and Human Behavior should be of interest to anyone in the behavioral and evolutionary sciences and to all those concerned with the role of language in human behavior. (shrink)

Human beings possess external stores in which they put all sorts of goods to use them at some later time. In this paper we investigate this typically human adaptation using agent-based simulations. We show that the use of external stores explains many aspects of human life, allowing the agents to reduce their dependence on both the environment and the current state of their body and to be more efficient in extracting the energy contained in the environment. We (...) analyse the spatial behaviour of agents with external stores located in specific positions of the environment and we find that these agents tend to develop a sedentary life. We discuss how stores can be at the origin of many human mental and social phenomena such as the acquisition of a more extended temporal perspective, specialisation in producing different types of goods, and exchange of goods.

Human beings persist in an extraordinary range of ecological settings, in the process exhibiting enormous behavioural diversity, both within and between populations. People vary in their social, mating and parental behaviour and have diverse and elaborate beliefs, traditions, norms and institutions. The aim of this theme issue is to ask whether, and how, evolutionary theory can help us to understand this diversity. In this introductory article, we provide a background to the debate surrounding how best to understand behavioural diversity (...) using evolutionary models of human behaviour. In particular, we examine how diversity has been viewed by the main subdisciplines within the human evolutionary behavioural sciences, focusing in particular on the human behavioural ecology, evolutionary psychology and cultural evolution approaches. In addition to differences in focus and methodology, these subdisciplines have traditionally varied in the emphasis placed on human universals, ecological factors and socially learned behaviour, and on how they have addressed the issue of genetic variation. We reaffirm that evolutionary theory provides an essential framework for understanding behavioural diversity within and between human populations, but argue that greater integration between the subfields is critical to developing a satisfactory understanding of diversity.

My brand of evolutionary economics recognizes, highlights, that modern economies are always in the process of changing, never fully at rest, with much of the energy coming from innovation. This perspective obviously draws a lot from Schumpeter. Continuing innovation, and the creative destruction that innovation engenders, is driving the system. There are winners and losers in the process, but generally the changes can be regarded as progress. The processes through which economic activity and performance evolve has a lot in common (...) with evolution in biology. In particular, at any time the economy is marked by considerable variety, there are selection forces winnowing on that variety, but also continuing emergence of new ways of doing things and often economic actors. But there also are important differences from biological evolution. In particular, both innovation and selection are to a considerable degree purposive activities, often undertaken on the basis of relatively strong knowledge. (shrink)

In a volume that traverses multiple disciplines, Michael Robbins proposes that the structures of the mind that distinguish us as uniquely human also incline us towards destructive behaviours on a personal and societal level. Psychoanalysis was created by Freud in an effort to understand neurosis and psychosis, the names he gave to individual human destructiveness. His understanding was limited and incorrect because the science of evolution and the disciplines of sociology and cultural anthropology were in their infancy when (...) he formulated his ideas. He did not comprehend that destructiveness is qualitatively different in humans than in other species and he ignored the problem of how biological instincts become mental processes. These limitations left psychoanalysis with one of its most perplexing unsolved problems, the mysterious leap from mind to body. The book explains how neoteny, the prolonged period of post-natal immaturity that distinguishes humans from other animals, requires and enables complex learning from caregivers. It is the knowledge acquired from this learning and its intergenerational transmission that links the biological theory of evolution with the psychosocial theory of psychoanalysis and explains how the human species is unique. The book will be of interest to those who want to learn about how integrating the findings of evolutionary science, primatology, sociology and cultural anthroplogy with the theory of psychoanalysis expands our understanding of what makes humans unique and its implications for the future of our species, and empowers us to influence the destiny of humankind.

In this paper, I critically summarize John Cartwrtight’s Evolution and Human Behavior and evaluate what he says about certain moral implications of Darwinian views of human behavior. He takes a Darwinism-doesn’t-rock-the-boat approach and argues that Darwinism, even if it is allied with evolutionary psychology, does not give us reason to be worried about the alterability of our behavior, nor does it give us reason to think that we may have to change our ordinary practices and (...) views concerning free-will and moral responsibility. In response, I contend that Darwinism, when it is allied with evolutionary psychology, makes for a more potent cocktail than Cartwright suspects. (shrink)

'Gaining control' tells the story of how human behavioral capacities evolved from those of other animal species. Exploring what is known about the psychological capacities of other groups of animals, the authors reconstruct a fascinating history of our own mental evolution. The result is a provocative and insightful book.

The biological and neurological capacity to symbolize, and the products of behavioral, cognitive, sociocultural, linguistic, and technological uses of symbols (symbolism), are fundamental to every aspect of human life. The Oxford Handbook of Human Symbolic Evolution explores the origins of our characteristically human abilities - our ability to speak, create images, play music, and read and write. The book investigates how symbolization evolved in human evolution and how symbolism is expressed across the various areas of (...) class='Hi'>human life. The field is intrinsically interdisciplinary - considering findings from fossil studies, scientific research from primatology, developmental psychology, and of course linguistics. Written by world leading experts, thirty-eight topical chapters are grouped into six thematic parts that respectively focus on epistemological, psychological, anthropological, ethological, linguistic, and social-technological aspects of human symbolic evolution. The handbook presents an in-depth but comprehensive and interdisciplinary overview of the of the state of the art in the science of human symbolic evolution. This work will be of interest to academics and students active in all fields contributing to the study of human evolution. (shrink)

Humans are moral creatures. Among all life on Earth, we alone experience rich moral emotions, follow complex rules governing how we treat one another, and engage in moral dialogue. But how did human morality evolve? And can humans become morally evolved? -/- In A Better Ape, Victor Kumar and Richmond Campbell draw on the latest research in the biological and social sciences to explain the key role that morality has played in human evolution. They explore the moral traits (...) that humans share with chimpanzees; how a more complex moral mind enabled Homo sapiens to arise and out-compete other human species; and the place of morality alongside historic revolutions in technology and social organization. Throughout the book, Kumar and Campbell argue that morality co-evolved with intelligence and complex sociality. Morality prevents societal collapse and enables complex knowledge. -/- After unearthing the ancient origins of human morality, Kumar and Campbell use evolutionary theory to deliver profound insights about how to advance moral progress and resist moral regress, such as reducing animal suffering on industrial farms; capitalizing on the recent revolution in gay rights to foster a nascent revolution in transgender rights; opposing intersectional inequality that impacts women and people of color in lower socioeconomic classes; and addressing major problems of global inequality, especially impending crises of injustice caused by anthropogenic climate change. Understanding how we evolved--and how we continue to evolve--can help us become a better ape. (shrink)

In this controversial new book O'Hear takes a stand against the fashion for explaining human behavior in terms of evolution. He contends that while the theory of evolution is successful in explaining the development of the natural world in general, it is of limited value when applied to the human world. Because of our reflectiveness and our rationality we take on goals and ideals which cannot be justified in terms of survival-promotion or reproductive advantage. O'Hear examines the (...) nature of human self-consciousness, and argues that evolutionary theory cannot give a satisfactory account of such distinctive facets of human life as the quest for knowledge, moral sense, and the appreciation of beauty; in these we transcend our biological origins. It is our rationality that allows each of us to go beyond not only our biological but also our cultural inheritance: as the author says in the Preface, "we are prisoners neither of our genes nor of the ideas we encounter as we each make our personal and individual way through life.".

Are humans too generous and too punitive? Many researchers have concluded that classic theories of social evolution (e.g., direct reciprocity, reputation) are not sufficient to explain human cooperation; instead, group selection theories are needed. We think such a move is premature. The leap to these models has been made by moving directly from thinking about selection pressures to predicting patterns of behavior and ignoring the intervening layer of evolved psychology that must mediate this connection. In real world environments, (...) information processing is a non-trivial problem and details of the ecology can dramatically constrain potential solutions, often enabling particular heuristics to be efficient and effective. We argue that making the intervening layer of psychology explicit resolves decades-old mysteries in the evolution of cooperation and punishment. (shrink)

Although evidence of teaching behaviour has been identified in some nonhuman species, human teaching appears to be unique in terms of both the breadth of contexts within which it is observed, and in its responsiveness to needs of the learner. Similarly, cultural evolution is observable in other species, but human cultural evolution appears strikingly distinct. This has led to speculation that the evolutionary origins of these capacities may be causally linked. Here we provide an overview of contrasting perspectives (...) on the relationship between teaching and cultural evolution in humans, and briefly review previous research which suggests that cumulative culture can occur without teaching. We then report the results of a novel experimental study in which we investigated how the benefits of teaching may depend on the complexity of the skill to be acquired. Participants were asked to tie knots of varying complexity. In our Teaching condition, opportunities to interact with an experienced partner aided transmission of the most complex knots, but not simpler equivalents, relative to exposure to completed products alone, and also relative to information about the process of completion. We conclude by considering the plausibility of various accounts of the evolutionary relationship between teaching and cultural evolution in humans. (shrink)

This essay reviews one of the most recent books in a trend of new publications proffering evolutionary theorising about aesthetics and the arts—themes within an increasing literature on aspects of human life and human nature in terms of evolutionary theory. Stephen Davies’ The Artful Species links some of our aesthetic sensibilities with our evolved human nature and critically surveys the interdisciplinary debate regarding the evolutionary status of the arts. Davies’ engaging and accessible writing succeeds in demonstrating the (...) maturity and scope of the field and his critique is timely and unparalleled. A laudable effort, however it may have benefited from espousing a co-evolutionary model more explicitly. Moreover there may be reason to question the usefulness of the standard set of distinctions (‘adaptation’, ‘spandrel’, ‘technology’) that Davies appeals to. (shrink)

René Girard's interdisciplinary theory of human culture, its origins, and its evolution, constitutes one of the more ambitious theories available in scholarship, with manifold applications in the humanities, interdisciplinarians, the human sciences, and peace studies scholars.1 I will not rehearse that theory here but briefly recall that he has argued: that pre-cognitive imitation is a key factor driving human behavior and gives rise to numerous benefits and problems, and that early human mimetic capacity coevolved with (...) and through "the victimage mechanism"—i.e., group murder of a victim, which gave birth to the...

One of the particular problems in the debate between science and theology regarding human origins seems to be an apparent controversy between the continuous character of evolutionary processes leading to the origin of Homo sapiens and the punctual understanding of the act of creation of man seen as taking place in a moment in time. The paper elaborates scientific arguments for continuity or discontinuity of evolution, and what follows, for the existence or nonexistence of a clear borderline between our (...) species and the rest of the living world. It is argued that, due to the conventional character of the notion of species, anthropology is unable to point to a moment in time or a place on Earth when or where Homo sapiens came into existence as a ‘really new’ species. The argument of the non˗specificity of humans is reinforced by considering emotional homologies between man and apes, “cultural” transmission of the patterns of behaviour in animals, or their mental and communicational abilities. All this is in line with a more general philosophical view of ontological continuity of the world. However, the argument is counterbalanced by pointing to such human characteristics as the ability to use abstract notions, or those forms of human behaviour which do not seem to have their animal analogues. In turn, various possibilities of theological interpretations of the act of creation of man are pointed out and a question is considered as to what extent theology is interested in a "momentary" account of this act. By pointing to theological accounts proposed as early as the 2nd century, it is argued that a vision of God – the craftsman who ‘builds’ its creation step by step, or even less restrictive forms of divine interventionism, are theologically inadequate. The original opposition between the continuity of evolutionary processes and ‘punctual’ character of creation is thus weakened and, from that perspective, a solution to the controversy in question is sought. One of such solutions, an “evolutionary model of creation”, a form of evolutionary creationism, proposed by a Polish philosopher Kazimierz Kloskowski, is presented. This model is based on two assumptions, stemming from process philosophy and evolutionary epistemology. The need to apply them in constructing a coherent view on evolution and creation is critically considered in the paper. (shrink)

What do we gain from the scientific study of religion? One possibility is that religious contexts are unique, and cognition within these contexts is worth understanding. Another possibility is that religion can be viewed as a laboratory for understanding psychology and culture more broadly. Rather than limiting the study of religion to a single context, I argue that the study of religion is useful precisely because it illuminates secular psychological and cultural processes. I first outline my practical approach to psychology (...) and religion, focusing on how people use religion to advance mundane goals. I then discuss several domains in which studying religion has led to important insights, including culture, prejudice, and cognition. This article is an extended version of an Early Career Award address given at the International Association for the Psychology of Religion meeting in 2023 in Groningen, Netherlands. (shrink)

The pseudoscience of evolutionary psychology purports to explain human behaviors by reference to an ancestral environment (essentially, a hunting‐gathering way of life) in which we evolved. Contemporary human behaviors are allegedly governed directly by genes that reflect adaptation to this environment by natural selection. However, the evolutionary process is much more complex than this reductionist approach implies, and adaptation cannot involve the fine‐tuning of structures or behaviors within individuals or species: natural selection can only affect entire organisms, not (...) their components. Similarly, genetic processes are too complex to admit this simplistic view. Instead, our flexible, complex human behaviors probably represent an emergent acquisition. (shrink)

In a dynamic world, mechanisms allowing prediction of future situations can provide a selective advantage. We suggest that memory systems differ in the degree of flexibility they offer for anticipatory behavior and put forward a corresponding taxonomy of prospection. The adaptive advantage of any memory system can only lie in what it contributes for future survival. The most flexible is episodic memory, which we suggest is part of a more general faculty of mental time travel that allows us not (...) only to go back in time, but also to foresee, plan, and shape virtually any specific future event. We review comparative studies and find that, in spite of increased research in the area, there is as yet no convincing evidence for mental time travel in nonhuman animals. We submit that mental time travel is not an encapsulated cognitive system, but instead comprises several subsidiary mechanisms. A theater metaphor serves as an analogy for the kind of mechanisms required for effective mental time travel. We propose that future research should consider these mechanisms in addition to direct evidence of future-directed action. We maintain that the emergence of mental time travel in evolution was a crucial step towards our current success. (shrink)

The current project introduces a general theory and supporting models that offer a plausible explanation and viable mechanism for generating and perpetuating prosocial behavior. The proposed mechanism is preferential detachment and the theory proposed is that agents utilizing preferential detachment will sort themselves into social arrangements such that the agents who contribute a benefit to the members of their group also do better for themselves in the long run. Agents can do this with minimal information about their environment, the (...) other agents, the future, and with minimal cognitive/computational ability. The conclusion is that self-organizing into groups that maintain prosocial behaviors may be simpler and more robust than previously thought. The primary contribution of this research is that a single, simple mechanism operating in different contexts generates the conceptually distinct prosocial behaviors achieved by other models, and in a manner that is more amenable to evolutionary explanations. It also bears importantly on explanations of the evolution of our moral experiences and their connection with prosociality. (shrink)

Recent years have seen the growing promise of cultural evolutionary theory as a new approach to bringing human behaviour fully within the broader evolutionary synthesis. This review of two recent seminal works on this topic argues that cultural evolution now holds the potential to bring together fields as disparate as neuroscience and social anthropology within a unified explanatory and ontological framework.

As proposed for the emergence of modern languages, we argue that modern uses of languages (pragmatics) also evolved gradually in our species under the effects of human self‐domestication, with three key aspects involved in a complex feedback loop: (a) a reduction in reactive aggression, (b) the sophistication of language structure (with emerging grammars initially facilitating the transition from physical aggression to verbal aggression); and (c) the potentiation of pragmatic principles governing conversation, including, but not limited to, turn‐taking and inferential (...) abilities. Our core hypothesis is that the reduction in reactive aggression, one of the key factors in self‐domestication processes, enabled us to fully exploit our cognitive and interactional potential as applied to linguistic exchanges, and ultimately to evolve a specific form of communication governed by persuasive reciprocity—a trait of human conversation characterized by both competition and cooperation. In turn, both early crude forms of language, well suited for verbal aggression/insult, and later more sophisticated forms of language, well suited for persuasive reciprocity, significantly contributed to the resolution and reduction of (physical) aggression, thus having a return effect on the self‐domestication processes. Supporting evidence for our proposal, as well as grounds for further testing, comes mainly from the consideration of cognitive disorders, which typically simultaneously present abnormal features of self‐domestication (including aggressive behavior) and problems with pragmatics and social functioning. While various approaches to language evolution typically reduce it to a single factor, our approach considers language evolution as a multifactorial process, with each player acting upon the other, engaging in an intense mutually reinforcing feedback loop. Moreover, we see language evolution as a gradual process, continuous with the pre‐linguistic cognitive abilities, which were engaged in a positive feedback loop with linguistic innovations, and where gene‐culture co‐evolution and cultural niche construction were the main driving forces.

The authors demonstrate that unselfish behavior is in fact an important feature of both biological and human nature. Their book provides a panoramic view of altruism throughout the animal kingdom--from self-sacrificing parasites to the human capacity for selflessness--even as it explains the evolutionary sense of such behavior.

Behavioral genetics and cultural evolution have both revolutionized our understanding of human behavior – largely independent of each other. Here, we reconcile these two fields under a dual inheritance framework, offering a more nuanced understanding of the interaction between genes and culture. Going beyond typical analyses of gene–environment interactions, we describe the cultural dynamics that shape these interactions by shaping the environment and population structure. A cultural evolutionary approach can explain, for example, how factors such as rates of (...) innovation and diffusion, density of cultural subgroups, and tolerance for behavioral diversity impact heritability estimates, thus yielding predictions for different social contexts. Moreover, when cumulative culture functionally overlaps with genes, genetic effects become masked, unmasked, or even reversed, and the causal effects of an identified gene become confounded with features of the cultural environment. The manner of confounding is specific to a particular society at a particular time, but a WEIRD (western, educated, industrialized, rich, and democratic) sampling problem obscures this boundedness. Cultural evolutionary dynamics are typically missing from models of gene-to-phenotype causality, hindering generalizability of genetic effects across societies and across time. We lay out a reconciled framework and use it to predict the ways in which heritability should differ between societies, between socioeconomic levels, and other groupings within some societies but not others, and over the life course. An integrated cultural evolutionary behavioral genetic approach cuts through the nature–nurture debate and helps resolve controversies in topics such as IQ. (shrink)

A radically immersive exploration of three pivotal moments in the evolution of human consciousness, asking what kinds of creatures humans were, are, and might yet be.

This article takes an evolutionary “reverse engineering” standpoint on Homo discens, learning man, to track down the mechanisms that played a pivotal role in the natural selection of human being. The approach is “evolutionary sociological”—as opposed to gene-centred or psychologising—and utilises notions of co-evolutionary organism–environment transactions and niche construction. These are compatible with a Deweyan theory of action, which entails that in action one cannot but learn and one can only learn in action. Special attention is paid to apprentice-like (...) learning-by-doing peculiar to human socio-cultural niches since the Pleistocene, which has permitted each subsequent generation to learn the many habits and skills needed in utilising the affordances of action that constitute their ecological niche. Affordances and actions have changed over the history of human–environment transactions, but the core mechanisms of human learning have not changed much. It is increasingly important to appreciate these mechanisms now in the global age “knowledge society,” which is in a way similar to the Pleistocene era: characterised by uncertainty and life-determining problem-situations without any ready-made solutions, it calls for capacities to adapt to changing circumstances, and thus apprentice-like learning in action supported by savvy epistemological engineering of learning environments.

While many philosophers agree that evolutionary theory has important implications for the study of ethics, there has been no consensus on what these implications are. I argue that we can better understand these implications by examining two related yet distinct issues in evolutionary theory: the evolution of our moral beliefs and the evolution of cooperative behavior. While the prevailing evolutionary account of morality poses a threat to moral realism, a plausible model of how altruism evolved in human beings (...) provides the grounding for a research program that focuses on achieving some of the more practical goals shared by ethicists. †To contact the author, please write to: Department of Political Science, Economics, and Philosophy, College of Staten Island/City University of New York, 2800 Victory Blvd., Staten Island, NY 10314; e‐mail: [email protected].

Guided by neuroscience, animal behavior, evolution, philosophy, and psychology, Asma burrows deep into the human psyche to look right at the enigmatic but powerful engine that is our improvisational creativity—the source, he argues, of our remarkable imaginational capacity. How is it, he asks, that a story can evoke a whole world inside of us? How are we able to rehearse a skill, a speech, or even an entire scenario simply by thinking about it? How does creativity go beyond (...) experience and help us make something completely new? And how does our moral imagination help us sculpt a better society? As he shows, we live in a world that is only partly happening in reality. Huge swaths of our cognitive experiences are made up by “what-ifs,” “almosts,” and “maybes,” an imagined terrain that churns out one of the most overlooked but necessary resources for our flourishing: possibilities. Considering everything from how imagination works in our physical bodies to the ways we make images, from the mechanics of language and our ability to tell stories to the creative composition of self-consciousness, Asma expands our personal and day-to-day forms of imagination into a grand scale: as one of the decisive evolutionary forces that has guided human development from the Paleolithic era to today. The result is an inspiring look at the rich relationships among improvisation, imagination, and culture, and a privileged glimpse into the unique nature of our evolved minds. (shrink)

Understanding the link between brain evolution and the evolution of distinctive features of modern human cognition is a fundamental challenge. A still unresolved question concerns the co-evolution of tool behavior (i.e., tool use or tool making) and language. The shared neurocognitive processes hypothesis suggests that the emergence of the combinatorial component of language skills within the frontal lobe/Broca's area made possible the complexification of tool-making skills. The importance of the frontal lobe/Broca's area in tool behavior is somewhat (...) surprising with regard to the literature on neuropsychology and cognitive neuroscience, which has instead stressed the critical role of the left inferior parietal lobe. Therefore, to be complete, any version of the shared neurocognitive processes hypothesis needs to integrate the potential interactions between the frontal lobe/Broca's area and the left inferior parietal lobe as well as their co-evolution at a phylogenetic level. Here, we sought to provide the first elements of answer through the use of the massive deployment framework, which posits that evolutionarily older brain areas are deployed in more cognitive functions (i.e., they are less specific). We focused on the left parietal cortex, and particularly the left areas PF, PGI, and anterior intraparietal (AIP), which are known to be involved in tool use, language, and motor control, respectively. The deployment of each brain area in different cognitive functions was measured by conducting a meta-analysis of neuroimaging studies. Our results confirmed the pattern of specificity for each brain area and also showed that the left area PGI was far less specific than the left areas PF and AIP. From these findings, we discuss the different evolutionary scenarios depicting the potential co-evolution of the combinatorial and generative components of language and tool behavior in our lineage.

Language evolution resulted from changes in our biology, behavior, and culture. One source of these changes might be human self-domestication. Williams syndrome (WS) is a clinical condition with a clearly defined genetic basis and resulting in a distinctive behavioral and cognitive profile, including enhanced sociability. In this paper we show evidence that the WS phenotype can be satisfactorily construed as a hyper-domesticated human phenotype, plausibly resulting from the effect of the WS hemydeletion on selected candidates for domestication (...) and neural crest function. Specifically, we show that genes involved in animal domestication and neural crest development and function are significantly dysregulated in the blood of subjects with WS. We also discuss the consequences of this link between domestication and WS for our current understanding of language evolution. (shrink)
