Two computer simulations are investigated that model interaction of cultural evolution of language and biological evolution of adaptations to language. Both are agent‐based models in which a population of agents imitates each other using realistic vowels. The agents evolve under selective pressure for good imitation. In one model, the evolution of the vocal tract is modeled; in the other, a cognitive mechanism for perceiving speech accurately is modeled. In both cases, biological adaptations to using and learning speech evolve, even though (...) the system of speech sounds itself changes at a more rapid time scale than biological evolution. However, the fact that the available acoustic space is used maximally (a self‐organized result of cultural evolution) is constant, and therefore biological evolution does have a stable target. This work shows that when cultural and biological traits are continuous, their co‐evolution may lead to cognitive adaptations that are strong enough to detect empirically. (shrink)

Together with language, music is perhaps the most distinctive behavioral trait of the human species. Different hypotheses have been proposed to explain why only humans perform music and how this ability might have evolved in our species. In this paper, we advance a new model of music evolution that builds on the self-domestication view of human evolution, according to which the human phenotype is, at least in part, the outcome of a process similar to domestication in other mammals, triggered by (...) the reduction in reactive aggression responses to environmental changes. We specifically argue that self-domestication can account for some of the cognitive changes, and particularly for the behaviors conducive to the complexification of music through a cultural mechanism. We hypothesize four stages in the evolution of music under self-domestication forces: (1) collective protomusic; (2) private, timbre-oriented music; (3) small-group, pitch-oriented music; and (4) collective, tonally organized music. This line of development encompasses the worldwide diversity of music types and genres and parallels what has been hypothesized for languages. Overall, music diversity might have emerged in a gradual fashion under the effects of the enhanced cultural niche construction as shaped by the progressive decrease in reactive (i.e., impulsive, triggered by fear or anger) aggression and the increase in proactive (i.e., premeditated, goal-directed) aggression.

Historical language change (), like evolution itself, is a fact; and its implications for the biological evolution of the human capacity for language acquisition () have been ably explored by many contemporary theorists. However, Christiansen & Chater's (C&C's) revolutionary call for a replacement of phylogenetic models with glossogenetic cultural models is based on an inadequate understanding of either. The solution to their lies before their eyes, but they mistakenly reject it due to a supposed Gene/;culture co-evolution poses a series of (...) difficult theoretical and empirical problems that will be resolved by subtle thinking, adequate models, and careful cross-disciplinary research, not by oversimplified manifestos.

Species evolve, very slowly, through selection of genes which give rise to phenotypes well adapted to their environments. The cultures, including the languages, of human communities evolve, much faster, maintaining at least a minimum level of adaptedness to the external, non- cultural environment. In the phylogenetic evolution of species, the transmission of information across generations is via copying of molecules, and innovation is by mutation and sexual recombination. In cultural evolution, the transmission of information across generations is by learning, and (...) innovation is by sporadic invention or borrowing from other cultures. This much is the foundational bedrock of evolutionary theory. But things get more complicated; there can be gene-culture co-evolution. Prior to the rise of culture, the physical environment is the only force shaping biological evolution from outside the organism, and cultures themselves are clearly constrained by the evolved biological characteristics of their members. But cultures become part of the external environment, and influence the course of biological evolution. For example, altruistic cultures with developed medical knowledge reduce the cost to the individual of carrying genes disposing to certain pathologies (such as diabetes); and such genes become more widespread in the populations maintaining such cultures. Assortative mating can affect biological evolution, and particular cultures may influence the factors which are sorted for in mating. (For a careful discussion of the effects of cultural evolution on natural selection, see Cavalli-Sforza and Bodmer, 1971:774- 804). This paper examines mechanisms involved in the co-evolution of a biological trait, the critical period for language acquisition, and a property of human cultures, the size of their languages. A gene/culture interaction will be shown that can be described as a kind of symbiosis, but perhaps more aptly as an `arms race'. In this introduction, we will sketch the basic mechanics of the interaction in very broad terms; the rest of the paper will explain and justify the details. The implications of our model for second language acquisition are given toward the end of the paper. (shrink)

Many people feel compelled to disassociate themselves from wrongdoing. We call judgments to the effect “disassociation intuitions.” Do disassociation intuitions have a common cause? Why do they seem so obvious and resistant to countervailing reasons? How did they become so widespread? Here, we argue that disassociation intuitions are a natural product of gene‐culture co‐evolution. We also consider the mechanism that gene‐culture co‐evolution employed to achieve this result, arguing that a plausible candidate is disgust and its cultural echoes. This (...) theory of disassociation intuitions suggests a promising research program in the philosophy of psychology, which provides new ways of thinking about higher cognitive emotions, and biologically constrained cognitive capacities generally.

Several evolutionary accounts of human social cognition posit that language has co-evolved with the sophisticated mindreading abilities of modern humans. It has also been argued that these mindreading abilities are the product of cultural, rather than biological, evolution. Taken together, these claims suggest that the evolution of language has played an important role in the cultural evolution of human social cognition. Here we present a new computational model which formalises the assumptions that underlie this hypothesis, in order to explore how (...) language and mindreading interact through cultural evolution. This model treats communicative behaviour as an interplay between the context in which communication occurs, an agent’s individual perspective on the world, and the agent’s lexicon. However, each agent’s perspective and lexicon are private mental representations, not directly observable to other agents. Learners are therefore confronted with the task of jointly inferring the lexicon and perspective of their cultural parent, based on their utterances in context. Simulation results show that given these assumptions, an informative lexicon evolves not just under a pressure to be successful at communicating, but also under a pressure for accurate perspective-inference. When such a lexicon evolves, agents become better at inferring others’ perspectives; not because their innate ability to learn about perspectives changes, but because sharing a language with others helps them to do so.

In lieu of an abstract, here is a brief excerpt of the content:Introduction:Beyond Nature/Culture Dualism: Let's Try Co-Evolution Instead of "Control"Ronnie Hawkins (bio)In the original call for papers for this special issue, nature/culture dualism was characterized as a way of thinking that holds human culture and nonhuman nature to be radically different ontological spheres, hyperseparated and oppositional, or, as Val Plumwood maintains in her essay, an orientation that assumes "separate casts of characters in separate dramas." In the human sphere, individuals (...) are unique and their lives are precious (at least theoretically), with concerns understood "from the inside," in terms of experience, intention and agency. In the sphere of nature, on the other hand, nonhuman beings are seen "from the outside," at best as replaceable members of species or populations needed for ecosystem functioning and, at worst, as unagentive, thinglike objects open for unbridled human exploitation. With our vast information and communication systems now largely in place, however, our human "noösphere" is rapidly enlarging to place us firmly within the biosphere (which, of course, in the imagery of Venn diagrams, must make up the larger circle on the screen), illuminating "both casts in both dramas," or perhaps joining all actors on the stage in a many-act, multidimensional play, the denoument of which, whether or not the extant lifeforms on this [End Page 1] planet will continue to evolve, remains as yet unwritten. The five essays in this collection speak to these points, and together they develop an alternative vision to our present dualistic impasse, seeing multiple natural agencies engaged with humanity in ongoing co-evolution and, as Freya Mathews suggests, raising the hope for a synergistic restructuring of lifeways that may yet save us from anthropogenic catastrophe.In "The Culture of Nature As Seen Through Mississippian Geographies," Jeff Baldwin shows us the broad scope of interacting agents, human and nonhuman, biological and geological, in what he terms "the nature-culture of the Mississippi River," as highlighted by the recent devastation of human habitation along the Gulf Coast of the United States wrought by Hurricanes Katrina and Rita. By enacting a role in which we "believe [our]selves to rule over a mechanistic world," we humans have, over the last century or so, stemmed the natural flooding of the Mississippi, rerouting the sediments that maintained and extended the delta, funneling them into the sea and thereby bringing about the subsidence and erosion of hundreds of square miles of coastal land. Concomitantly, we have let agricultural runoff from the huge Mississippi drainage basin eject excess nutrients into the Gulf of Mexico, stimulating algal blooms and die-offs, depleting the water of oxygen so as to create a hypoxic "dead zone" that is now the size of Massachusetts, and (though Baldwin does not discuss this aspect of the problem) we have released enough petrochemical pollution in the area to have earned the lower reaches of the River the name "Cancer Alley" decades ago. A failure to grasp the import of these large anthropogenic effects is, sadly, evident in calls for rebuilding the New Orleans area according to the same mechanistic model that has already proven so inadequate. Baldwin observes that the earth changes wrought through human cultural innovation often occur so rapidly, or have their negative feedbacks technologically so displaced through time and space, that their eventual impacts on the larger system may initially go unappreciated. His vision of "the culture of nature," however, is ultimately an optimistic one, since his functional understanding of culture is that it ultimately works toward mutualism, promoting increasingly appropriate relationships among all interacting components, and he finds evidence of a growing effort to establish an "intentional co-evolution," a conscious alignment of human projects with the ongoing projects of a living nature that encompasses them. [End Page 2]If Baldwin's essay helps us see our human activities "from the outside"—not just "from within" prevailing human culture, where they seem taken-for-granted necessities given a certain form of social construction, but as they alternatively appear inside biospherical space, often as inappropriate, exploitative interferences and intrusions—Stacey Sowards' essay, "Identification Through Orangutans: Destabilizing the Nature/Culture Dualism," explores the potential for our connecting with nonhuman life "from the inside," relating...

Biology is seen not merely as a privileged oppressor of women but as a co-victim of masculinist social assumptions. We see feminist critique as one of the normative controls that any scientist must perform whenever analyzing data, and we seek to demonstrate what has happened when this control has not been utilized. Narratives of fertilization and sex determination traditionally have been modeled on the cultural patterns of male/female interaction, leading to gender associations being placed on cells and their components. We (...) also find that when gender biases are controlled, new perceptions of these intracellular and extracellular relationships emerge. (shrink)

Much has been written about the self, yet its evolution and functioning are matters of controversy in evolutionary psychology. The article argues that it is an evolved capacity, essential for co-evolutionary processes, including cultural development, to occur. A model of self-regulation is offered to explain its adaptive functioning, elaborating William James’ I-me distinction, and drawing upon contemporary analyses in social psychology and neuroscience. The model is used to illustrate how adaptive behavior is facilitated by the exercise of self-control, to defer (...) and re-order goals, revise perceptions of the world, modify conceptions of the self, and alter repertoires of learned action sequences, heuristics, and habits. It also identifies potential areas of dysfunction, mediated by self-deception and misperception. Through this lens one can see how leadership is a historically co-evolving function of social systems, changing to meet altered circumstances. The recursive relationship involves interaction between changing leader–follower relationships, within which leaders’ self-regulation is a central process. Individual differences in leaders as agents are thus also critical. The article concludes by considering the need for insight in order to steer these co-evolving functions in directions that help us as a species to master the global challenges and threats we face in our times.

Tim Lewens aims to understand what it means to take an evolutionary approach to cultural change, and why it is that these approaches are sometimes treated with suspicion. While making a case for the value of evolutionary thinking for students of culture, he shows why the concerns of sceptics should not dismissed as mere prejudice, confusion, or ignorance. Indeed, confusions about what evolutionary approaches entail are propagated by their proponents, as well as by their detractors. By taking seriously the problems (...) faced by these approaches to culture, he shows how such approaches can be better formulated, where their most significant limitations lie, and how the tools of cultural evolutionary thinking might become more widely accepted.

Smith gives an excellent overview on research in language evolution, in which he discusses several recent models of how linguistic systems and the cognitive capacities involved in language learning may have co‐evolved. He illustrates how combined pressures on language learning and communication/use produce compositionally structured languages. Once in place, a (culturally transmitted) communication system creates new selection pressures on the capacity for acquiring these systems.

The structuring of our environment to provide cues and reminders for ourselves is common: We leave notes on the fridge, we have a particular place for our keys where we deposit them, making them easy to find. We alter our world to streamline our cognitive tasks. But how did hominins gain this capacity? What pushed our ancestors to structure their physical environment in ways that buffered thinking and began the process of using the world cognitively? I argue that the capacity (...) to engage in these behaviours is a by-product of increased tool investment and tool curation, which in turn was necessary because of increasingly heterogeneous environments. The minute tools are carried and cared for, they begin to undergo selection for added functions, becoming available as cognitive primers and as signals. I explore the trajectory of this co-evolutionary feedback loop of hominins and their tools, and demonstrate the role tools have in shaping our thinking. (shrink)

The sound system of a language must be able to support a perceptual contrast between different words in order to signal communicatively relevant meaning distinctions. In this paper, we use a simple agent-based exemplar model in which the evolution of sound-category systems is understood as a co-evolutionary process, where the range of variation within sound categories is constrained by functional pressure to keep different words perceptually distinct. We show that this model can reproduce several observed effects on the range of (...) sound variation. We argue that phonological systems can be seen as finding a relative optimum of variation: Efficient communication is sustained while at the same time, hidden category variation provides pathways for future evolution.

Commentary on Lesly Newson and Peter Richerson, Moral Beliefs about Homosexuality: Testing a Cultural Evolutionary Hypothesis.

David Steen and co-authors in this journal offer a philosophical argument to support an “Evolutionary Community Concept” to identify what they call “evolutionary communities.” They describe these as “unique collections of species that interact and have co-evolved in a given geographic area” and that include “co-evolved dependencies between different parts of a community.” Steen et al. refer to the coevolution of assemblages, collections, communities, dependencies, interspecific and abiotic interactions, and traits, but they do not define “co-evolution” or provide an example (...) in which co-evolution has been demonstrated. There may be as many ways to explain interactions among species as these interactions themselves; they may result, for example, from ecological fitting and phenotypic plasticity. In this paper, I argue that standard Darwinian Theory explains intraspecific microevolution or descent with modification within an interbreeding and potentially continuous population. The power, mechanism, or force that causes interspecific co-evolution, especially at the community scale, requires further explanation. (shrink)

While the “symbolic” meaning of early body ornamentation has received the lion’s share of attention in the debate on human origins, this paper sets out to explore their aesthetic and agentive dimensions, for the purpose of explaining how various ornamental forms would have led interacting groups to form a cultural identity of their own. To this end, semiotics is integrated with a new paradigm in the archaeology of mind, known as the theory of material engagement. Bridging specifically Peirce’s pragmatic theory (...) and Malafouris’ enactive take on aesthetics allows us to appreciate the formation of aesthetic ideals through the agentive effects of material signs. It is thus proposed that, by attending to the interrelation between form, effect, and affect, members of social groups would have come to appreciate the ways in which their ornamental culture resembles and differs from that of neighbouring groups. Following the Lund conception of cultural semiotics, I argue that models of Ego-culture would have come to evolve along Alter-cultures that also employ ornaments, and against Alius-cultures that have yet to develop or adopt personal decoration. The aesthetic ideals associated with early body ornaments must have therefore played a catalytic role in the formation and communication of group membership. I thus close by proposing that the origins of new cultural identities can be explained by tracing the co-development of ideas and ideals. (shrink)

Our purpose in this essay is to introduce new concepts in a wide and recursive view of the systemic consequences of the following biological facts that I and we have presented that can be resumed as: that as living systems we human beings are molecular autopoietic system; that living systems live only as long as they find themselves in a medium that provides them with all the conditions that make the realization of their living possible, that is, in the continuous (...) conservation of their relation of adaptation to the circumstances in which they find themselves; that as a living system exists only in a relation of adaptation with the medium that operates as its ecological niche, its reproduction necessarily occurs as a process of systemic duplication or multiplication of the ecological organism-niche unity that it integrates; that the worlds of doings that we generate as languaging beings in our conversations, explanations, reflections and theories are part of our ecological niche; and that we human beings as living beings that exist in languaging, are biological–cultural beings in which our cultural and our biological manners of existences can be distinguished but cannot be separated. Of the systemic consequences of these biological facts that we consider in this essay, we wish to mention two as the principal: that the diversification of manners of living produced in biological evolution is the result of differential survival in a changing medium through the conservation of adaptation, and not through competitive survival of the best; and that we in our living as languaging human beings are the epistemological fundament of all that we do and know as such.

Human predispositions to fatness and obesity are best understood in the context of cultural and biological evolution. Both genes and cultural traits that were adaptive in the context of past food scarcities play a role today in the etiology of maladaptive adult obesity. The etiology of obesity must account for the social distribution of the condition with regard to gender, ethnicity, social class, and economic modernization. This distribution, which has changed throughout history, undoubtedly involves cultural factors. A model of culture (...) is presented that has advantages over an undifferentiated concept of the “environment” for hypothesis generation. Cultural predispositions to obesity are found in the productive economy, the mode of reproduction, social structure, and cultural beliefs about food and ideal body size. Cross-cultural comparison can contribute to an understanding of the prevalence of obesity in some modern affluent societies. (shrink)

In Stages of Thought, Michael Barnes examines a pattern of cognitive development that has evolved over thousands of years--a pattern manifest in both science and religion. He describes how the major world cultures built upon our natural human language skills to add literacy, logic, and, now, a highly critical self-awareness. In tracing the histories of both scientific and religious thought, Barnes shows why we think the way that we do today. Although religious and scientific modes of thought are often portrayed (...) as contradictory-one is highly rational while the other appeals to tradition and faith-Barnes argues that they evolved together and are actually complementary. Using the developmental thought of Piaget, he argues that cultures develop like individuals in that both learn easier cognitive skills first and master the harder ones later. This is especially true, says Barnes, because the harder ones often require first the creation of cognitive technology like writing or formal logic as well as the creation of social institutions that teach and sustain those skills. Barnes goes on to delineate the successive stages of the co-evolution of religious and scientific thought in the West, from the preliterate cultures of antiquity up to the present time. Along the way, he covers topics such as the impact of literacy on human modes of thought; the development of formalized logic and philosophical reflections; the emergence of an explicitly rational science; the birth of formal theologies; and, more recently, the growth of modern empirical science. This groundbreaking book offers a thorough and persuasive argument in favor of the development of modes of thought across cultures. It will serve as an invaluable resource for historians of religion, philosophers and historians of science, and anyone interested in the relationship between religion and science. (shrink)

We have transited far from an ancient culture of hunters to the world of today when our conditions as human beings are changing. We recognize that our biological-cultural co-evolution has privileged reason.

The term exaptation, describing the phenomenon that an existing trait or tool proves to be of new adaptive value in a new context, is flourishing in recent literature from cultural evolution and cognitive archaeology. Yet there also exists an older literature from the nineteenth and twentieth centuries which studied more or less systematically the phenomenon of “change of function” in culture and tool use. Michel Foucault and Ludwig Noiré, who devoted themselves to the history of social institutions and material tools, (...) respectively, occupy an important place among them. This article offers a brief overview of this literature and attempts to show that it provided ideas that remain relevant to current approaches to cognitive archaeology, in particular regarding attempts to understand the impact of technological evolution on the human mind.

Abstract The concept of evolution challenges us to an ongoing effort to interpret its significance. The challenge has several dimensions: (1) to calm the debate that divides Americans in arguing whether evolution is at odds with biblical traditions; (2) to integrate evolution into one's personal philosophy of life or religious faith; (3) to note the importance of the story form for rendering evolution; and (4) to evaluate evolution as a creation story. Evolution is portrayed as a drama in five acts: (...) cosmic, biological, cultural, moral, and spiritual. The discussion concludes with reflection on humans as co-creators whose task is to become the storytellers of evolution. The author presents this interpretation as a fuller concept of evolution.

Ever since The Origin of Species, but increasingly in recent years, parallels and analogies have been drawn between biological and cultural evolution, and methods, concepts, and theories that have been developed in evolutionary biology have been used to explain aspects of human cultural change (e.g., Muller 1870; Darwin [1871] 2003; Pitt-Rivers 1875; James 1880; Huxley 1955; Gerard et al. 1956; Campbell 1975; Cavalli-Sforza and Feldman 1981; Durham 1992; Henrich and McElreath 2003; Mesoudi et al. 2004, 2006; Boyd and Richerson 2005; (...) Richerson and Boyd 2005). Many others, however, while accepting the need for some form of evolutionary approach to culture, have consistently emphasized the differences between biological and cultural evolution (e.g., Gabora 2004; Sperber and Claidiere 2006; Tëmkin and Eldredge 2007), with these differences often presented as being problematic for existing evolutionary analyses of culture. Here I argue that this is largely a false debate, given that its protagonists agree on the majority of key points. Apparent disagreement may stem partly from simple differences in emphasis, and partly from the diversity of both biological and cultural evolutionary processes. (shrink)

Ethical concerns regarding agricultural practices can be found to co-evolve with technological developments. This paper aims to create an understanding of ethics that is helpful in debating technological innovation by studying such a co-evolution process in detail: the development and adoption of the milking robot. Over the last decade an increasing number of milking robots, or automatic milking systems (AMS), has been adopted, especially in the Netherlands and a few other Western European countries. The appraisal of this new technology in (...) ethical terms has appeared to be a complicated matter. Compared to using a conventional milking parlor, the use of an AMS entails in several respects a different practice of dairy farming, the ethical implications and evaluation of which are not self-evident but are themselves part of a dynamic process. It has become clear that with its use, the entire practice of dairy farming has been reorganized around this new device. With a robot, cows must voluntarily present themselves to be milked, whereby an ethical norm of (individual) freedom for cows can be seen to emerge together with this new technology. But adopting a robot also implies changes in what is considered to be a good farmer and an appropriate relation between farmer and cow. Through interviews, attending “farmers’ network” meetings in the Netherlands, and studying professional literature and dedicated dairy farming web forums, this paper traces the way that ethical concerns are a dynamic part of this process of rearranging a variety of elements of the practice of dairy farming.

In recent years, the research field of the evolution of art has witnessed contributions from a wide range of disciplines across the "three cultures". In this thesis, I make both a critical review of existing explanations, and try to do elucidate the evolution of art by employing insights, methods and concepts from different disciplines. First, I critically evaluate the evidentiary criteria from standard evolutionary psychology some accounts employ to demonstrate that art qualifies as a human biological adaptation. I argue that (...) these criteria do not suffice to make that claim. Furthermore, I make the case for a cultural evolutionary approach to the arts. One commonly used evidentiary criterion for art as adaptation is the “tight fit” between artnbsp;human cognition, which is interpreted as suggesting that cognition has undergone selection to produce and appreciate art. However, disentangling cultural and genetic evolution allows formulating thenbsp;hypothesis that art has evolved culturally to match human cognition. Second, I observe that in ancient and modern hunter gatherer societies, artistic activities are virtually alwaysnbsp;with ritual. I discuss what this implies for the adaptive significance of art. Specifically, if the arts have culturally evolved in function of ritualistic purposes, their adaptive value has depended on the adaptiveness of ritual. Third, because architecture is characterized by the combination of utilitarian and aesthetic aspects, it is particularly interesting from an evolutionary perspective and therefore I devote special attention to it. Employing the cross-species comparative approach, I investigate two main purposes human architecture has in common with nonhuman animal constructions: protection andnbsp;Based on the phylogenetic approach I establish that protection may have been the primary function of building aptitudes in humannbsp;and that building was later co-opted for signaling purposes. Subsequently, I comparatively evaluate thenbsp;of signaling models in the cultural evolution of architectural aesthetics. Furthermore I combine insights from environmental psychology, niche construction and cultural evolution theory to develop the hypothesis that a function of religious monumental architecture may have been to support nbsp;or even to galvanize nbsp;social learning. Finally, I connect the account I developed to the cognitive science of religion. I complement the frequently held view that religious monumental architecture is a costly signal with the mechanism of sensory exploitation. I attempt to demonstrate that by exploiting thenbsp;response of awe in religious followers, religious monumental architecture promotes and regulates prosocial behavior and creates in them an openness to adopt supernatural beliefs. Fourth, I dealnbsp;the evolution of visual art, paying again special attention to cultural evolution andnbsp;explanatory value of sensory exploitation. I assert that the relatively late appearance of figurative art in the course of human evolution may be attributed to an increase in the number of social learning opportunities within and between human populations at that time. I support this assertion with archaeological data that indicate overall population growth and increased population densities at that time. These demographic changes, I argue, have allowed the retention and accumulation of innovations required for figurative art making. Contrary to previous accounts, I furthermore aim to show that this process doesnbsp;require figurative art to have served adaptive purposes. Employing sensory exploitation, I establish that figurative art could have evolved by exploiting pre-existing biases of evolved psychology. The dominant themes of upper Paleolithic and late stone age figurative art, animals and humans, seem to support this contention. Fifth, I present a number of experimental studies I conducted to verify whether contemporary art experts would have socially learned to resist exploitation of evolved psychology. One aspect ofrsquo;s exploitative power may be that it elicits aesthetic pleasure by pushing “pleasure buttons” that evolved for other purposes. Consequently, spectators may trade-off rewards from indulging in art and biological activities, resulting in less effort being allocated to reproduction. I contend that, while the generalnbsp; may indeed be exploited, experts, who are typically being exposed to high doses of art, may have socially learned to resist exploitation by selectively preferring art from prestigious art contexts. The latter would be in line with the claim that prestige bias may trump content biases of evolved psychology. The results of three experimental studies supportnbsp;contention. I find that laypeople's art appreciation is positively affected by a content bias for attractive faces, mediated by aesthetic pleasure, whereas experts' appreciation is positively affected by prestige and mediated by admiration for the artist. Moreover, experts confer lower appreciation to attractive compared to moderately attractive content, which is consistentnbsp;the contention that expertise and the use of prestige are associatednbsp;resistance against beautiful content that exploits evolved preferences. This research thus suggests that expertise moderates content and context biases, which may be of relevance to an ongoing debate about their relative importance as drivers of cultural evolution. In addition, this study provides a tentative but novel explanation for the fact, famously established by philosopher Arthur Danto, that beauty lost its central position in Western art during the 20th century. However my findings cannot exclude alternative explanations for the fact that art expert appreciation deviates from evolved aesthetic preferences. Further research may experimentally assess the role of prestige bias and resistance as drivers of this deviation versus other, previously suggested, potential processes. For example, preferences of experts may deviate on account of the fact that art serves as a badge of elite group membership and thus expert art appreciation as a means to distinguish oneself from the masses. Alternatively, art experts may seek intellectual challenges instead of pushing pleasure buttons. Future research may experimentally verify the respective roles of these different hypothesized mechanisms. In addition, it may be investigated how insights from sexual selection research may help elucidating the different processes at play in cultural evolution and particularly in the cultural evolution of art appreciation, given the commonalities between sexual selection and cultural selection models.

“Teleosemantic” or “biosemantic” theories form a strong naturalistic programme in the philosophy of mind and language. They seek to explain the nature of mind and language by recourse to a natural history of “proper functions” as selected-for effects of language- and thought-producing mechanisms. However, they remain vague with respect to the nature of the proposed analogy between selected-for effects on the biological level and phenomena that are not strictly biological, such as reproducible linguistic and cultural forms. This essay critically explores (...) various interpretations of this analogy. It suggests that these interpretations can be explicated by contrasting adaptationist with pluralist readings of the evolutionary concept of adaptation. Among the possible interpretations of the relations between biological adaptations and their analogues in language and culture, the two most relevant are a linear, hierarchical, signalling-based model that takes its cues from the evolution of co-operation and joint intentionality and a mutualistic, pluralist model that takes its cues from mimesis and symbolism in the evolution of human communication. Arguing for the merits of the mutualistic model, the present analysis indicates a path towards an evolutionary pluralist version of biosemantics that will align with theories of cognition as being environmentally “scaffolded”. Language and other cultural forms are partly independent reproducible structures that acquire proper functions of their own while being integrated with organism-based cognitive traits in co-evolutionary fashion.

We propose a conceptual model that maps the causal pathways relating biological evolution to cultural change. It builds on conventional evolutionary theory by placing emphasis on the capacity of organisms to modify sources of natural selection in their environment (niche construction) and by broadening the evolutionary dynamic to incorporate ontogenetic and cultural processes. In this model, phenotypes have a much more active role in evolution than generally conceived. This sheds light on hominid evolution, on the evolution of culture, and on (...) altruism and cooperation. Culture amplifies the capacity of human beings to modify sources of natural selection in their environments to the point where that capacity raises some new questions about the processes of human adaptation.

The resulting gender imbalance in favor of men in the adult population causes a number of serious social problems, including increased violence against women and an increasing number of “forced bachelors” in many areas. Here we concentrate on the sex ratio at birth in China and model two causal factors specific to Chinese culture: a traditional preference for sons over daughters and a preference for brides (...) to move to their husband’s natal home (virilocal marriage). We use cultural niche construction models to explore the interacting effect of both son preference and marriage-type preference on the demography of the region. Finally, we discuss the implications of this model for policy interventions in the future. (shrink)

In what sense can we aim to moralize the very system upon which we rely to formulate our notions of morality? This is the most fundamental issue raised by any discussion around the “moralization of capitalism”. In an even more general manner, one could express the issue in terms of the puzzle of second-order morality: How exactly is it possible to pass a moral judgment on our categories of moral judgment? How can our norms of morality be said to be (...) “immoral”, thus calling for “(re-)moralization”? This puzzle rests, of course, on a particular version of historicism to which I will subscribe here: Capitalism as a system of practical interaction structures, and hence as a culture, has evolved out of moral imperatives and hence must be seen as a reflection and an enactment, rather than a violation, of these moral imperatives. Thus, as long as the moral norms and the interaction structures remain congruent, there is no straightforward to way to call capitalism “immoral”. The only legitimate reason to issue a call for its “(re-)moralization” is if this congruence has come undone; but how can that be, if not because some set of processes internal to capitalism has actually altered either (a) the structures of interaction, or (a’) the norms of morality, or (a”) both, in such a way that (b) they have become maladjusted and (c) this maladjustment is actually experienced as such by agents who are able to effect the required readjustments? But how can such internal processes be triggered? This is the puzzle of second-order morality when applied to capitalism. (shrink)

Recent field studies have broadened our view on cultural performances in animals. This has consequences for the concept of cumulative culture. Here, we deconstruct the common individualist and differential approaches to culture. Individualistic approaches to the study of cultural evolution are shown to be problematic, because culture cannot be reduced to factors on the micro level of individual behavior but possesses a dynamic that only occurs on the group level and profoundly affects the individuals. Naive individuals, as a prerequisite of (...) an atomistic perspective, do not exist. We address the construction of a social approach to culture by introducing an inevitable social embedding of the individual development of social beings. The sociological notion of “habitus” as embodied cultural capital permits us to understand social transmission of behavioral components on a very basic level, resulting in a cumulative effect. Bits of information, movement, handling of material, attitudes, and preferences below distinct functional units are acquired through transfer mechanisms simpler than emulation and imitation such as peering, participation, co-performance, or engagement with a material environment altered by group members. The search for a zero point of cumulative culture becomes as useless as the search for a zero point of culture. Culture is cumulative. (shrink)

Universal Grammar (UG) is indeed evolutionarily implausible. But if languages are just to a large primate brain, it is hard to see why other primates do not have complex languages. The answer is that humans have evolved a specialized and uniquely human cognitive architecture, whose main function is to compute mappings between arbitrary signals and communicative intentions. This underlies the development of language in the human species.

Several writers on animal ethics defend the abolition of most or all animal agriculture, which they consider an unethical exploitation of sentient non-human animals. However, animal agriculture can also be seen as a co-evolution over thousands of years, that has affected biology and behavior on the one hand, and quality of life of humans and domestic animals on the other. Furthermore, animals are important in sustainable agriculture. They can increase efficiency by their ability to transform materials unsuitable for human consumption (...) and by grazing areas that would be difficult to harvest otherwise. Grazing of natural pastures is essential for the pastoral landscape, an important habitat for wild flora and fauna and much valued by humans for its aesthetic value. Thus it seems that the environment gains substantially when animals are included in sustainable agricultural systems. But what about the animals themselves? Objections against animal agriculture often refer to the disrespect for animals’ lives, integrity, and welfare in present intensive animal production systems. Of the three issues at stake, neither integrity nor animal welfare need in principle be violated in carefully designed animal husbandry systems. The main ethical conflict seems to lie in the killing of animals, which is inevitable if the system is to deliver animal products. In this paper, we present the benefits and costs to humans and animals of including animals in sustainable agriculture, and discuss how to address some of the ethical issues involved. (shrink)

In the present article, a depiction of complexity versus time will be used for the construction of a novel form of a tree of life, called The Pattern of Life, comprising the biological, cultural, and scientific forms of the evolutionary process. This diagram accentuates the implication of the successive modifications of developmental programs, in the cultural and scientific realms coupled to a feedback mechanism that is decisive for the accelerating pace of complexity growth, also suggested to be of support of (...) a cautious prediction of future evolution.

The co-evolutionary concept of three-modal stable evolutionary strategy of Homo sapiens is developed. The concept based on the principle of evolutionary complementarity of anthropogenesis: value of evolutionary risk and evolutionary path of human evolution are defined by descriptive (evolutionary efficiency) and creative-teleological (evolutionary correctness) parameters simultaneously, that cannot be instrumental reduced to other ones. Resulting volume of both parameters define the vectors of biological, social, cultural and techno-rationalistic human evolution by two gear mechanism — genetic and cultural co-evolution and techno-humanitarian (...) balance. Explanatory model and methodology of evaluation of creatively teleological evolutionary risk component of NBIC technological complex is proposed. Integral part of the model is evolutionary semantics (time-varying semantic code, the compliance of the biological, socio-cultural and techno-rationalist adaptive modules of human stable evolutionary strategy).

ABSTRACT Nietzsche's investigation into the origins of morality bears some striking similarities to contemporary investigations into human evolution. Here I investigate these similarities, using a comparison between Nietzsche's GM and Gould and Lewontin's influential “Spandrels” essay as a departure point. I argue that Nietzsche defends a proto-evolutionary psychology about morality, where the inheritance of enduring biological drives conflicts with our culturally evolved moral system. While Nietzsche's claims about the evolution of morality fit well within a Darwinian framework of natural selection, (...) his claims about our underlying biology do not. Those claims cohere better with the non-Darwinian views found in nineteenth-century German biology and embryology. (shrink)

This essay in the "anthropology of science" is about how cognition constrains culture in producing science. The example is folk biology, whose cultural recurrence issues from the very same domain-specific cognitive universals that provide the historical backbone of systematic biology. Humans everywhere think about plants and animals in highly structured ways. People have similar folk-biological taxonomies composed of essence-based species-like groups and the ranking of species into lower- and higher-order groups. Such taxonomies are not as arbitrary in structure and content, (...) nor as variable across cultures, as the assembly of entities into cosmologies, materials or social groups. (shrink)

How is word meaning established, and how do individuals acquire it? What ensures the uniform understanding of word meaning in a linguistic community? In this paper I draw from cultural attraction theory and use folk biology as an example domain and address these questions by treating meaning acquisition as an inferential process. I show that significant variation exists in how individuals understand the meaning of inclusive biological labels such as “plant” and “animal” due to variation in their salience in contemporary (...) ethnic minority groups in southwest China, and I present historical textual evidence that the meaning of inclusive terms is often unstable but can be sustained by such cultural institutions as religion and education, which provide situations in which the meaning of linguistic labels can be unambiguously inferred.

Arbib offers a comprehensive, elegant formulation of brain/language evolution; with significant implications for social as well as biological sciences. Important psychological antecedents and later correlates are presupposed; their conceptual enrichment through protosign and protospeech is abbreviated in favor of practical communication. What culture and whether protosign and protospeech involve a protoculture are not considered. Arbib also avoids dealing with the question of evolution of mind, consciousness, and self.
