Cultural evolution, producing group‐level adaptations, is more problematic than the cultural evolution of individually confirmable skills, but it probably has occurred. The “conformist transmission,” described by Boyd and Richerson (1985), leads local social units to become homogeneous in anadaptive, as well as adaptive, beliefs. The resulting intragroup homogeneity and inter‐group heterogeneity makes possible a cultural selection of adaptive group ideologies.All archaic urban, division‐of‐labor social organizations had to overcome aspects of human nature produced by biological evolution, due to the predicament of (...) genetic competition among the cooperators. The universal norms found in archaic moral systems are seen as curbs to this human nature, reinforced by beliefs in invisible sanction systems and rewarding and punishing afterlives (as in heaven or reincarnation). Perhaps the ubiquity of lavishly wasteful royal funerals is to be explained as contributing to this function. (shrink)

Despite the reality of intersex individuals whose biological markers do not necessarily all point towards a traditional binary understanding of either male or female, the vast majority of sports divide competition into categories based on a binary notion of biological sex and develop policies and regulations to police the divide. In so doing, sports governing bodies (SGBs) adopt an imperfect model of biological sex in order to serve their particular purposes, which, typically, will include protecting the fundamental sporting value (...) of fair competition. Yet, one potential consequence of enforcing such an approach would seem to be the exclusion or marginalization of individuals whose biological development does not fit within the binary model, whether due to genetics or through a choice to undergo medical intervention to better represent a chosen gender identity. Any such exclusion or marginalization will inevitably tend to undermine another fundamental value of sport, that of inclusivity. In the context of those with differences of sex development, SGBs appear to be faced with a difficult problem: dealing with a conflict between two fundamental values of sport. Different approaches to this problem have been suggested, with some academics proposing that sports organisations, in general, ought to prioritise fairness above, while others suggest the need to ‘balance’ competing values or even to prioritise inclusion over fairness. However, it is argued that any of these approaches are, in principle, justifiable as any sport should be free to prioritise or balance its own values. What seems more important for any SGB is the need for a rational and transparent justification of regulations that pursue fair competition at the expense of inclusivity. Furthermore, where fair competition and inclusivity are fundamental values, any such justification would seem to demand adherence to some basic norms. First, the regulations should be built on (and articulate) a consistent and principled basis of what ‘fair competition’ means in a particular sport. Second, any regulations should only exclude or restrict participation to the minimum degree necessary to achieve the sense of fair competition so articulated. Third, SGBs should be transparent about what their values are and where their priorities lie so that participants and other stakeholders are able to make an informed choice as to whether they wish to participate in, support, or be associated with a particular sport. With reference to the adoption of the Eligibility Regulations for Athletes with Differences of Sex Development (the ‘DSD Regulations’) by the International Association of Athletic Federations (IAAF), this article seeks to evaluate whether the approach of the IAAF satisfied these basic requirements.

This paper examines social determinants of resource competition among Tsimane Amerindian women of Bolivia. We introduce a semi-anonymous experiment (the Social Strategy Game) designed to simulate resource competition among women. Information concerning dyadic social relationships and demographic data were collected to identify variables influencing resource competition intensity, as measured by the number of beads one woman took from another. Relationship variables are used to test how the affiliative or competitive aspects of dyads affect the extent (...) of prosociality in the game. Using a mixed-modeling procedure, we find that women compete with those with whom they are quarreling over accusations of meat theft, mate competition, and rumor spreading. They also compete with members of their social network and with those who were designated as cooperative helpers or as close kin. Women take fewer beads from desired friends, neighbors, and from those viewed as enemies. We interpret favoritism toward enemies as resulting from fear of retribution. Our results suggest that social relations among women are multifaceted and often cannot be simplified by exclusive focus on genetic relatedness, physical proximity, or reciprocity. We argue that a complex understanding of cooperation and competition among women may require important contextual information concerning relationship history in addition to typical features of resource ecology.

Historical studies on the relationship between science and diplomacy tend to focus on events since World War II and on initiatives for the maintenance of peace or to achieve cooperation over contentious matters. This article presents the case of José Vicente Barbosa du Bocage (1823–1907), a Portuguese zoologist who had formal diplomatic responsibilities in a context of competition for the colonization of Africa in the nineteenth century. He used his knowledge in African geography to implement colonial and diplomatic strategies (...) that aimed at outcompeting rival powers. The development of a network of actors with scientific, colonial, and diplomatic expertise was crucial for the negotiations that involved the partition of the Congo basin, which resulted in victories for Portugal that surpassed the country's marginal political relevance at the international level and had long‐lasting consequences.

The human ability to form large, coordinated groups is among our most impressive social adaptations. Larger groups facilitate synergistic economies of scale for cooperative breeding, such economic tasks as group hunting, and success in conflict with other groups. In many organisms, genetic relationships provide the structure for sociality to evolve via the process of kin selection, and this is the case, to a certain extent, for humans. But assortment by genetic affiliation is not the only mechanism that (...) can bring people together. Affinity based on symbolically mediated and socially constructed identity, or cultural kinship, structures much of human ultrasociality. This paper examines how genetic kinship and two kinds of cultural kinship—affinal kinship and descent—structure the network of cooperating whale hunters in the village of Lamalera, Indonesia. Social network analyses show that each mechanism of assortment produces characteristic networks of different sizes, each more or less conducive to the task of hunting whales. Assortment via close genetic kin relationships (r = 0.5) produces a smaller, denser network. Assortment via less-close kin relations (r = 0.125) produces a larger but less dense network. Affinal networks are small and diffuse; lineage networks are larger, discrete, and very dense. The roles that genetic and cultural kinship play for structuring human sociality is discussed in the context of these results. (shrink)

In “patchwork” families, full siblings, maternal and paternal half-siblings, and non-related children are raised together, and sometimes, genetically related children are separated. As their number is steadily growing, the investigation of the factors that influence within-family relations is becoming more important. Our aim was to explore whether people differentiate between half- and full-siblings in their social relations as implied by the theory of inclusive fitness, and to test whether co-residence or genetic relatedness improves sibling relations to a larger extent. (...) We administered the Sibling Relationship Questionnaire to 196 individuals who were in contact with full-, half-, or step-siblings in their childhood. We built Generalized Linear Mixed Models models to test for the effects of relatedness and co-residence on sibling relations. In general, a higher degree of relatedness was associated with better sibling relations, but only among those who did not live together during childhood. Co-resident siblings’ overall pattern of relation quality was not influenced by the actual level of genetic relatedness. In contrast to this, full siblings reported having experienced more conflicts during childhood than half-siblings, possibly resulting from enhanced competition for the same parental resources. The results suggest that inclusive fitness drives siblings’ relations even in recent industrial societies. However, among individuals who live together, the effect of relatedness might be obscured by fitness interdependence and the subjective feeling of kinship. (shrink)

Recent scholarship has steadily been opening up for philosophical study an increasingly wide range of the philosophical literature of antiquity. We no longer think only of Socrates, Plato and Aristotle, and their pre-Socratic forebears, when someone refers to the views of the ancient philosophers. Julia Annas has been one of the philosophers most closely engaged in the renewed study of Hellenistic philosophy over the past fifteen years, enabling herself and other scholars to acquire the necessary ground-level knowledge of the widely-dispersed (...) texts and the problems of interpretation—both historical and philosophical—that they present. In her new book she takes the next step. She presents to the general philosophical public of today an extended reconstruction of the systems of moral philosophy that were developed and pitted in competition with one another during the period when refinement and professionalism were at their height in Greek philosophy—between the end of the 4th and the middle of the 1st centuries B.C. These include the moral philosophies of Epicurus and his followers, several generations of Stoics, sceptical philosophers both Academic and Pyrrhonian, and the “hybrid” theories put together by Antiochus of Ascalon and other Stoic-influenced philosophers as part of the modernizing revival of Aristotelian ethical thought that took place in the 1st century B.C. She finds significant commonalities among these otherwise very disparate theories, and much of the book is devoted to examining these and showing how the conception of ethics and morality that is common to the ancient theorists compares with and differs from what we are familiar with in modern and contemporary theory. She traces these commonalities back to Aristotle in his ethical treatises, and accordingly includes Aristotle’s theory as one among those to be examined—indeed, in a significant sense as the intellectual father or grandfather of the rest of them. She leaves Plato’s dialogues out of account, and she has nothing to say about ethics and moral philosophy in the revived Platonism that gradually came to dominate philosophical thought in later antiquity. Her book, then, is a book about the structure and content of ancient ethical theory during the Hellenistic period, the period when Greek philosophy was at its high-point in professionalism and sophistication.

A simple model, illustrating the transition from a population of free swimming, solitary cells to one consisting of small colonies serves as a basis to discuss the evolution of the cooperative group. The transition is the result of a mutation of the dynamics of cell division, delayed cell separation leads to colonies of four cells. With this mutation cooperative features appear, such as synchronised cell divisions within colonies and coordinated flagellar function which enables the colony to swim in definite directions. (...) The selective advantages under given, environmental conditions are defined and the periods necessary for complete allelic replacement in small populations are calculated for asexual and sexual reproduction. The assumption of a steady-state population during allelic substitution is critically considered, particularly under conditions of competition. It is shown that density-dependent population control must operate in the process of selection. Sexual reproduction slows down the rate of selection even though all cells dre haploid. This phenomenon can be explained in general terms of `organizational dominance', where individual units coordinate the function of their neighbours which may be of a different allelotype.Cooperativity is pointed out as an a priori systemic feature which resides in the sub-units of systems, group formation and coordination appears thus as an almost inevitable event. A particular type of system described as ‘closed cycle of positive fitness interaction’ is discussed in more detail. It has the remarkable feature that its members cannot compete with each other; selection takes place between whole cycles .Gonium has a wide spectrum of `somatic plasticity' which enables it to assume various colonial configurations depending on physiological and environmental conditions. This feature can be explained as the result of dynamic flexibilities on the macro-molecular level. The particular relationship between the vast, molecular complexity and the relative simple dynamics of the cell cycle must lead eventually to the genetic fixation of an environmentally induced phenotype.

MacDonald develops an evolutionary perspective on Judaism. Judaism is conceptualized as a group evolutionary strategy characterized by a high degree of endogamy and resistance to genetic and cultural assimilation. Data are provided to support the author's theory that Judaism is characterized by a high level of within-group altruism and competition with outgroups. Finally, MacDonald argues that Judaism has been characterized by eugenic practices aimed at high intelligence and high investment parenting. After outlining a theory of evolutionary group strategies, (...) MacDonald discusses the evidence from modern studies showing population genetic differences between Jews and Gentiles. He then shows that Jewish religious writing points to a pronounced tendency toward idealizing endogamy and condemning exogamy, and he points to the ways religious ideology and practice have facilitated the genetic and cultural separation of Jews and Gentiles. He then reviews evidence for resource and reproductive competition and the importance of kin-based cooperation and altruism as well as assortative mating for intelligence and resource aquisition ability among Jews. This study is a highly original attempt to develop an evolutionary understanding of one of the world's great religions. As such, it will be of concern to scholars and researchers in the fields of sociobiology and religion as well as the general reading public. (shrink)

Competition over reproductive opportunities among members of one sex often harms the opposite sex, creating a conflict of interest between individual males and females. Recently, this battle of the sexes has become a paradigm in the study of intersexual coevolution. Here, we review recent theoretical and empirical advances suggesting that – as in any scenario of intraspecific competition – selfishness (competitiveness) can be influenced by the genetic relatedness of competitors. When competitors are positively related (e.g. siblings), (...) an individual may refrain from harming its competitor(s) and their mate(s) because this can improve the focal individual's inclusive fitness. These findings reveal that population genetic structure might be of paramount importance when studying the battle of the sexes. We conclude by identifying some new lines of research at the interface of sexual selection and social evolution. (shrink)

Bernard Malamud's God's Grace (1982) is a neo-Darwinian Beast Fable about morality in a thermonuclear age. It serves me as a starting point for a fresh look at the fundamental questions surrounding morality and altruism. There is no doubt any more that, from the standpoint of multilevel selection, morality is a form of compromise among competing spheres of genetic self-interest. The result is a tug-of-war between two adaptive vectors: the egoistic and competitive "me first" versus the prosocial and (...) cooperative "we-first.". (shrink)

Whereas many evolutionary models emphasize within-group cooperation or between-group competition in explaining human large-scale cooperation, recent work highlights a critical role for intergroup cooperation in human adaptation. Here we investigate intergroup cooperation in the domain of shotgun hunting in northern Republic of the Congo. In the Congo Basin broadly, forest foragers maintain relationships with neighboring farmers based on systems of exchange regulated by norms and institutions such as fictive kinship. In this study, we examine how relationships between Yambe farmers (...) and BaYaka foragers support stable intergroup cooperation in the domain of shotgun hunting. In the study village, shotgun hunting is based on a specialization-based exchange wherein Yambe farmers contribute shotguns and access to markets to buy cartridges and sell meat while BaYaka foragers contribute their specialized forest knowledge and skill. To understand how costs and benefits are distributed, we conducted structured interviews with 77 BaYaka hunters and 15 Yambe gun owners and accompanied hunters on nine hunting trips. We found that hunts are organized in a conventional manner within a fictive kinship structure, consistent with the presence of intercultural mechanisms to stabilize cooperation. However, because bushmeat demand is high, gun owners can gain significant cash profit, while compensating hunters only with cigarettes, alcohol, and a traditional hunter’s portion of meat. To level payoffs, hunters strategically hide kills or cartridges from gun owners to feed their own families. Our results illustrate how each group prioritizes different currencies (e.g., cash, meat, family, intergroup relations) and provide insights into how intergroup cooperation is stabilized in this setting. The example of this long-standing intergroup cooperative system is discussed in terms of its contemporary entwinement with logging, the bushmeat trade, and growing market intersection. (shrink)

This Open Forum contribution critically interrogates the use of space race rhetoric in current discussions about artificial intelligence (AI). According to this rhetoric, similar to the space race of the twentieth century, AI development is portrayed as a rivalry among superpowers where one country will win and reap major benefits, while others will be left behind. Using this rhetoric to frame AI development tends to prioritize narrow and short-term economic interests over broader and longer-term societal needs. Three particularly problematic (...) aspects of using space race narrative in AI discussions are highlighted: first, perceiving technology development globally as a zero-sum game; second, pressuring governments to regulate less; and third, prioritising high technologies over social issues. This contribution invites to challenge underlying political assumptions of the AI space race discourse and to open up conversations about alternative futures. (shrink)

In Why We Cooperate, Tomasello addresses the problem of human uniqueness, which has become the focus for a lot of recent research at the frontier between the Humanities and the Life Sciences. Being both a developmental psychologist and a primatologist, Tomasello is especially well suited to tackle the subject, and the present book is the most recent one in a series of books and papers by himself and his colleagues. Tomasello’s basic position is squarely a dual-inheritance account, in which human (...) uniqueness is explained both through genetics and through culture. The main idea is that the phylogenetic specificity of humankind rests in its species-specific adaptation for sociability. The account offered by Tomasello contrasts human cooperation and altruism with nonhuman primate competition, and proposes that human altruism leads to shared intentionality. The evolutionary explanation Tomasello offers is that human ancestors were led through some kind of selection pressure to common foraging leading to collaboration and sharing. After outlining Tomasello’s position as it is described in the book, as well as the comments by Dweck, Spelke, Silk, and Skyrms which follow, I discuss Tomasello’s thesis, noting a few problems with his approach. These criticisms are based on his own work and on a number of his own other books and papers, as well as on other relevant work in the domain. (shrink)

Human genetic enhancement, examined from the standpoint of the new field of political bioethics, displaces the age-old question of truth: What is human nature? This book displaces that question with another: What kind of human nature should humans want to create for themselves? To answer that question, this book answers two others: What constraints should limit the applications of rapidly developing biotechnologies? What could possibly form the basis for corresponding public policy in a democratic society? Benjamin Gregg focuses on (...) the distinctly political dimensions of human nature, where politics refers to competition among competing values on which to base public policy, legislation, and political culture. This book offers citizens of democratic communities a broad perspective on how they together might best approach urgent questions of how to deal with the socially and morally challenging potential for human genetic engineering.

Understanding religion requires explaining why supernatural beliefs, devotions, and rituals are both universal and variable across cultures, and why religion is so often associated with both large-scale cooperation and enduring group conflict. Emerging lines of research suggest that these oppositions result from the convergence of three processes. First, the interaction of certain reliably developing cognitive processes, such as our ability to infer the presence of intentional agents, favors—as an evolutionary by-product—the spread of certain kinds of counterintuitive concepts. Second, participation in (...) rituals and devotions involving costly displays exploits various aspects of our evolved psychology to deepen people's commitment to both supernatural agents and religious communities. Third, competition among societies and organizations with different faith-based beliefs and practices has increasingly connected religion with both within-group prosociality and between-group enmity. This connection has strengthened dramatically in recent millennia, as part of the evolution of complex societies, and is important to understanding cooperation and conflict in today's world.

This 1989 volume presents a theory of capitalist collective action and a case study of the pre-World War II American coal industry to which the theory is applied.

He then explains under what conditions businesses would be able to organize their competition and identifies the economic and political factors that facilitate or inhibit this organization. The case (...) study not only illustrates the theory, but demonstrates how the competitive relations of capitalist firms are critically important determinants of their political behavior. The author argues that the traditional Marxist concern with conflict between workers and capitalists should be supplemented with a concern for the competitive conflicts among capitalists. (shrink)

Kin relations have a strong theoretical and empirical basis for explaining cooperative behavior. Nevertheless, there is growing recognition that context—the cooperative environment of an individual—also shapes the willingness of individuals to cooperate. For nomadic pastoralists in Norway, cooperation among both kin and non-kin is an essential predictor for success. The northern parts of the country are characterized by a history of herder-herder competition exacerbating between-herder conflict, lack of trust, and subsequent coordination problems. In contrast, because of a history (...) of herder-farmer competition, southern Norway is characterized by high levels of between-herder coordination and trust. This comparative study investigates the relative importance of “cooperative context” and kinship in structuring cooperative behavior using an experimental gift game. The main findings from this study were that in the South, a high level of cooperation around an individual pushes gifts to be distributed evenly among other herders. Nevertheless, kinship matters, since close kin give and receive larger gifts. In contrast, kinship seems to be the main factor affecting gift distribution in the North. Herders in the North are also concerned with distributing gifts equally, albeit limiting them to close kin: the level of intragroup cooperation drives gifts to be distributed evenly among other closely related herders. The observed regional contrasts in cooperative decisions fit with the different historical levels of conflict and trust in the two regions: whereas herders in the South are affected by both cooperative context and kinship, kinship seems to be the main determinant of cooperation in the North.

Human cooperation is highly unusual. We live in large groups composed mostly of non-relatives. Evolutionists have proposed a number of explanations for this pattern, including cultural group selection and extensions of more general processes such as reciprocity, kin selection, and multi-level selection acting on genes. Evolutionary processes are consilient; they affect several different empirical domains, such as patterns of behavior and the proximal drivers of that behavior. In this target article, we sketch the evidence from five domains that bear on (...) the explanatory adequacy of cultural group selection and competing hypotheses to explain human cooperation. Does cultural transmission constitute an inheritance system that can evolve in a Darwinian fashion? Are the norms that underpin institutions among the cultural traits so transmitted? Do we observe sufficient variation at the level of groups of considerable size for group selection to be a plausible process? Do human groups compete, and do success and failure in competition depend upon cultural variation? Do we observe adaptations for cooperation in humans that most plausibly arose by cultural group selection? If the answer to one of these questions is “no,” then we must look to other hypotheses. We present evidence, including quantitative evidence, that the answer to all of the questions is “yes” and argue that we must take the cultural group selection hypothesis seriously. If culturally transmitted systems of rules (institutions) that limit individual deviance organize cooperation in human societies, then it is not clear that any extant alternative to cultural group selection can be a complete explanation.

Our universe, science reveals, began in utter simplicity, then evolved into burgeoning complexity. Starting with subatomic particles, dissimilar entities formed associations—binding, bonding, growing, branching, catalyzing, cooperating—as “self” joined “other” following universal laws with names such as gravity, chemical attraction, and natural selection. Ultimately life arose in a world of dynamic organic chemistry, and complexity exploded with wondrous new potential. Fast forward to human evolution, and a tension that had existed for billions of years now played out in an unprecedented arena (...) of conscious calculation and cultural diversity. Cooperation interleaving with competition; intimacy oscillating with integrity—we dwell in a world where yin meets yang in human affairs on many levels. In The Fractal Self, John Culliney and David Jones uncover surprising intersections between science and philosophy. Connecting evidence from evolutionary science with early insights of Daoist and Buddhist thinkers, among others, they maintain that sagely behavior, envisioned in these ancient traditions, represents a pinnacle of human achievement emerging out of our evolutionary heritage. They identify an archetype, “the fractal self,” a person in any walk of life who cultivates a cooperative spirit. A fractal self is a sage in training, who joins others in common cause, leads from within, and achieves personal satisfaction in coordinating smooth performance of the group, team, or institution in which he or she is embedded. Fractal selves commonly operate with dedication and compassionate practice in the service of human society or in conserving our planet. But the competitive side of human nature is susceptible to greed and aggression. Self-aggrandizement, dictatorial power, and ego-driven enforcement of will are the goals of those following a self-serving path—individuals the authors identify as antisages. Terrorist leaders are an especially murderous breed, but aggrandizers can be found throughout business, religion, educational institutions, and governments. Humanity has reached an existential tipping point: will the horizon already in view expand with cooperative progress toward godlike emergent opportunities or contract in the thrall of corrupt oligarchs and tribal animosities? We have brought ourselves to a chaotic edge between immense promise and existential danger and are even now making our greatest choice. (shrink)

Spatial evolutionary game theory explains how cooperative traits can survive the intense competition in biological systems. If the spatial distribution allows cooperators to interact with each other frequently, the benefits of cooperation will outweigh the losses due to exploitation by selfish organisms. However, for a cooperative behavior to get established in a system, it needs to be found initially in a sufficiently large cluster to allow a high frequency of intracooperator interactions. Since mutations are rare events, this poses (...) the question of how cooperation can arise in a biological system in the first place. We present a simple model which captures two concepts from genetics that can explain how evolution overcomes the emergence problem. The first concept is, often in nature, a gene may not express its phenotype except under specific environmental conditions, rendering it to be a “silent” gene. The second key idea is that a neutral gene, one that does not harm or improve an organism’s survival chances, can still spread through a population if it is physically near to another gene that is positively selected. Through these two ideas, our model offers a possible solution to the fundamental problem of emergence of cooperation in biological systems. (shrink)

The present study is a differential study that describes the nature of the relationship between cooperation and altruistic behavior in a sample of gifted adolescents in three universities in Egypt and Kuwait University. It also identified the differences between males/females, and senior students/junior students in both cooperation and altruism. A total of 237 gifted adolescents—with average age 21.3 ± SD 2.6 years—from three Egyptian universities: Alexandria University, Sadat Academy for Management Sciences, and Suez University, and Kuwait University, were involved in (...) this study. Measures used in the study include the Scales for Rating the Behavioral Characteristics of Superior Students, Generative Altruism Scale, and The Cooperative/Competitive Strategy Scale. Results revealed that there is a significant positive relationship between altruism and cooperation among gifted adolescents. Also, findings show that there are statistically significant differences between males and females in both altruism and cooperation. In addition, there are differences statistically significant between senior students and junior students in both altruism and cooperation in favor of senior students. It is recommended that altruism and cooperation intervention-based programs should be designed to increase the adaptive behaviors of adolescents. (shrink)

Evolutionarily-minded scholars working on the most puzzling aspects of human cooperation-one-shot, anonymous interactions among non-kin where reputational information is not available-can be roughly divided into two camps. In the first, researchers argue for the existence of evolved capacities for genuinely altruistic human cooperation, and in their models emphasize the role of intergroup competition and selection, as well as group norms and markers of membership that reduce intragroup variability. Researchers in the second camp explain cooperation in terms of individual-level (...) decision-making facilitated by evolved cognitive mechanisms associated with well-established self- and kin-maximization models, as well as by ‘misfires’ that may result from these mechanisms interacting with novel environments. This essay argues that the manner in which culture provides information that de-anonymizes intragroup strangers suggests that neither evolved capacities for genuine altruism nor widespread misfires are necessary to account for anonymous, one-shot cooperation.

In 1991, the myotonic dystrophy gene was cloned by researchers from Cardiff, London, and elsewhere overseas. This article examines the relationships between the different research groups. It shows that the scientific collaboration on the myotonic dystrophy research was not a constant, stable feature of scientific progress but a process whereby the relationships among the scientists altered over time according to the stage of the research. This process was mediated by vested interests, by personalities, by the power differentials of the (...) groups, by the resources of the groups, by subcollaborations, and by interactions with those outside the main research network. The collaboration can be seen as a continuum, ranging from full cooperation with all parties to selected revelations to specific parties to intense competition. These cooperative and competitive relationships are seen primarily from the perspective of one research group, with whom intensive field research was conducted. (shrink)

Over the past several decades, we have argued that cultural evolution can facilitate the evolution of largescale cooperation because it often leads to more rapid adaptation than genetic evolution, and, when multiple stable equilibria exist, rapid adaptation leads to variation among groups. Recently, Lehmann, Feldman, and colleagues have published several papers questioning this argument. They analyze models showing that cultural evolution can actually reduce the range of conditions under which cooperation can evolve and interpret these models as indicating (...) that we were wrong to conclude that culture facilitated the evolution of human cooperation.

The controversies over genetically modified crops in India involve what Gieryn refers to as ‘boundary work’ in the ongoing competition for credibility and trustworthiness among claimsmakers with opposing points of view. Discourse about GM crops involves extensive drawing of boundaries by actors including policymakers, technocrats, NGOs, scientists, industrialists, and farmers. The issues raised range from governmental processes to moral and ethical implications, from environmental consequences to integration into the global economy. Those involved in these discussions frequently invoke the (...) idealized notions of farmers and farming in order to situate themselves within the boundary of a particular social category which may lend credibility to their claims. While Gieryn has focused primarily on scientists’ attempts to construct a boundary between science and non-science in order to establish themselves as experts, strengthen the credibility of their claims and avoid political interference in their intellectual activities, this article focuses on a different way in which knowledgeable and influential actors lay claim to trustworthiness by drawing a different kind of social boundary around themselves. This article will especially focus on the ways in which the category of farmers is used in the GM crop controversies by actors who are in a position to influence public policies regarding GM crops, especially in their efforts to justify their policy prescriptions. The thesis here is that GM crop controversies in India reflect elite actors’ attempts to compete for a shared social identity with farmers, thus constructing a context for the particular public policy prescriptions they support. The thesis is supported by a lexical item frequency analysis of discussion related to genetically modified cotton in India which demonstrates that boundary work using social identity of farmers plays a significant role in shaping the discourse surrounding the adoption and governance of GM crops.

Abstract.Agricultural restructuring has disproportionately impacted smaller US farms, such as those in Michigan where the average farm size is 215 acres. To keep agricultural land in production, entrepreneurial Michigan farmers are utilizing agritourism as a value-added way to capitalize on their comparative advantages, their diverse agricultural products, and their locations near large, urban, tourist-generating areas. Using focus groups, this paper illustrates how entrepreneurial farmers have strengthened Michigan agritourism by fostering producer networks through brochures and web linkages, information sharing in refining (...) the agritourism product, referrals to other agritourism businesses that serve different markets or offer different products, purchase linkages, and a regional approach to establishing agritourism destinations and increase visitation. Successful entrepreneurial, agritourism developers thus work cooperatively, rather than individualistically and competitively. Agritourism destinations facing stiff competition from alternative venues for leisure time and food purchases benefit from supportive linkages that help sustain a critical mass of producers who offer diverse goods, maintain land in agriculture, and thus, reinforce Michigan’s image for agritourism.

Chagnon’s analysis of a well-known axe fight in the Yanomamö village of Mishimishiböwei-teri (Chagnon and Bugos 1979) is among the earliest empirical tests of kin selection theory for explaining cooperation in humans. Kin selection theory describes how cooperation can be organized around genetic kinship and is a fundamental tool for understanding cooperation within family groups. Previous analysis on groups of cooperative Lamaleran whale hunters suggests that the role of genetic kinship as a principle for organizing cooperative human (...) groups could be less important in certain cases than previously thought (Alvard Human Nature 14:129–163, 2003b). Evidence that supports a strong role for genetic kinship—groups are found to be more related than expected by chance—may be spurious because of the correlation between social structure and genetic kinship. Reanalysis of Chagnon’s data using matrix regression techniques, however, confirms that genetic kinship was the primary organizing principle in the axe fight; affinal relations were also important, whereas lineage identity explained nothing.

In this study we argue that there is an interconnection between; the mechanistic worldview and competition, and the organic worldview and cooperation. To illustrate our main thesis we introduce two cases; first, Max Havelaar, a paradigmatic case of how business might function in an economy based upon solidarity and sustainability. Second, TINE, a Norwegian grocery corporation engaged in collusion in order to force a small competitor out of the market. On the one hand, in order to encourage market behaviour (...) that integrates economic, societal and environmental values we find that transparent cooperation within a context of an organic worldview takes care of important intrinsic as well as instrumental values. On the other hand, we find evidence for asserting that cooperation based upon a mechanistic worldview, typically leads to group egotistical consequences undermining the long term common good.

If people vote rationally for their economic interests, one would expect Democrats to be perennial favorites among working poor and middle class, and especially so in this year of economic downturn. Why then does polling show the election a tossup? A culture's moral compass is not an innate or logical determination, but an underdetermined product of historical contingency and willful choice. Belief in moral "rightness" or "truth" is always a matter of faith rather than reason. Only some professional philosophers, (...) jurists, scientists and academics believe that the principal point of political argument is, or ought to be, truth rather than persuasion, and that an argument's principal appeal should be reason rather than passion. The fundamental social constituent of economic and political culture in the United States was neither the individual nor the state, but the sectarian community. The religious community in the USA was a civic as well as moral community, a combination which infused American economic and political culture with particular dynamism. As Darwin noted, in competition between groups with similar levels of technology and population size, those groups will tend to win out that favor and transmit willingness to sacrifice some self interest for group interests. Religions with morally concerned deities arguably made the rise of civilization and large-scale cooperation between genetic strangers possible. (shrink)

The concept of dominance is used in the behavioral and biological sciences to describe outcomes in a variety of competitive interactions. In some taxa, a history of agonistic encounters among individuals modifies the course of future agonistic encounters such that the existence of a certain type of relationship can be inferred. If one is to characterize such relationships as dominance, however, then they must be distinguished from other kinds of interaction patterns for which the term tends to be used, (...) as well as from factors such as territoriality and "trained" winners and losers, which may also influence the expression of agonistic behavior. Operational definitions based on causal, functional, evolutionary, and ontogenetic considerations have been proposed. Reliability and validity problems have been discussed, but the dominance concept has proved useful despite methodological difficulties. The confusion of dominance relationships (which involve two or more individuals) with dominance ranks (which are assigned to a single individual) has obscured the possible evolutionary basis of dominance relationships. If benefits accrue to dominant members of pairs, then those attributes which allow an animal to establish dominance can be selected. Dominance per se and dominance ranks, on the other hand, cannot be genetically transmitted since they constitute relationships with other individuals rather than absolute attributes. Dominance rankings in particular may be useful for describing behavioral patterns within a group, but they may reflect our own ability to count rather than any important variable in social organization.

This article theorizes and analyzes how two aspects of the increasing accountingization of academia in the form of evaluative pressures and group identification, independently and interactively, work to cultivate academics’ self-interest for their social interactions with the scientific community, forming them to adopt more competitive orientations and cynical attitudes. Using data of a large number of faculty members from the 17 universities in Sweden, it is shown that evaluative pressures and group identification perceived by academics jointly reinforce each other in (...) affecting their competitive orientation, and that group identification strengthens the positive relation between evaluative pressures and academics’ rivalry notions and cynical attitudes. It is shown, contributing further to research on performance evaluation and the cultivation of self-interest and an egoistic ethical climate in academia, that it is evaluative pressures from peers rather than from performance measurements that are the major driver of an individual’s competitive orientation and cynical attitudes. It is also concluded that while evaluative pressures are related to an increase in academics' competitive orientations, which may be viewed as an intended effect from control designers in universities, such an orientation is inversely related to cooperativeness and openness toward others and goes hand in hand with an increase in having cynical attitudes about peers and the work environment. Control designers in universities may thus not be able to have the one without the other, something that raises ethical concerns for academic leaders to reflect upon when aiming at cultivating self-interest orientations of academics.

The complexity of our ‘object’ of study, leading to the question ‘what is really the city?’ requires the use of different levels of analyses. At the same time, a way must be found to develop an explanatory model that brings together the knowledge thus produced. The study of governance in the city is necessarily part of any research aimed at investigating empirically the processes regulating the social life. The key implication is to address its impact; a task made particularly complex (...) by the often difficult relationship between the implementation of governance and the interaction with a diversity of societal actors, for the ongoing dialectic between the formal and the informal in urban life. We often find that this dialectic produces ambiguity, unexpected results, gaps between planned objectives, and competition instead of cooperation among actors, pointing to the weakness of the rationalistic model of public action. Perhaps the most important lesson that we have learnt about government and governance is that the delusion that we feel when trying to understand urban policies results from our incapacity fully to grasp the complexity of human life.

The moral and political philosophy of Wilhelm Röpke is among the finest instances of European classical liberalism in the twentieth century, and in many occasions he stated that only a society which understands the importance of markets can be reconciled with human dignity. Röpke elaborated a political theory that focused on the harmony between moral principles and economic law. In this sense, his liberalism is unique not only because it defends private property and competition as pillars of a (...) thriving economy, but above all that it provides the preconditions of a society that can remain secure from the immorality of despotism and subsequent ethical degeneration. To that end he upheld an economic order based on voluntary cooperation as the basis for a more humane society, emphasizing the role of institutional competition and federalism. Röpke’s cultural conservatism should not therefore be misunderstood, as it is very much connected with his defense of the essential role of property. It is only in this sense that he found in liberal humanism a third way, which is not however situated halfway between the market and socialism, but which represents instead a defense of a competitive society that is aware of its own historical and cultural basis.

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)

Social network analysis has become an increasingly important tool among political scientists for understanding legislative cooperation in modern, democratic nation-states. Recent research has demonstrated the influence that group affinity (homophily) and mutual exchanges (reciprocity) have in structuring political relationships. However, this literature has typically focused on political cooperation where costs are low, relationships are not exclusive, and/or partisan competition is high. Patterns of legislative behavior in alternative contexts are less clear and remain largely unexamined. Here, we compare theoretical (...) expectations of cooperation in these contexts from the political and biosocial sciences and implement the first assessment of political alliance formation in a novel legislative environment where costs to cooperation are high and party salience low. We implement a stochastic actor-oriented model (SAOM) to examine bill floor sponsorship, a process in which a “floor sponsor” becomes the exclusive advocate for a colleague’s piece of legislation, in the Utah state legislature from 2005 to 2008—a context in which gender (male) and political party (Republican) supermajorities exist. We find that (1) party and gender homophily predict who legislators recruit as floor sponsors, whereas seniority does not, and (2) legislators frequently engage in reciprocal exchanges of floor sponsorship. In addition, whereas gender homophily increases the likelihood of reciprocity, party homophily decreases it. Our findings suggest that when the cost of cooperation is high, political actors use in-group characteristics for initiating alliances, but once a cooperative relationship is established with an out-group political member, it is reinforced through repeated exchanges. These findings may be useful for understanding the rise of political polarization and gridlock in democracies internationally. (shrink)

In this paper we examine the merit of bargaining theory, in its economic and ecological forms, as a model for understanding variation in the frequency of participation in cooperative fishing among men of Ifaluk atoll in Micronesia. Two determinants of bargaining power are considered: resource control and a bargainer’s utility gain for his expected share of the negotiated resource. Several hypotheses which relte cultural and life-course parameters to bargaining power are tested against data on the frequency of cooperative sail-fishing (...) participation. Consistent with predictions generated from bargaining theory, we show that (1) age is negatively correlated with cooperative fishing participation, (2) men of highranking clans and men with high levels of education fish less than men of low-ranking clans and less-educated men, (3) men with high expected utility gains from fishing returns fish more than men with low expected utility gains, (4) number of dependents is positively correlated with cooperative fishing participation, and (5) the number of young genetic offspring residing with a man is positively correlated with cooperative fishing participation, whereas the number of genetic offspring more than 13 years old who are residing with a man is negatively correlated with cooperative fishing participation.

In Republic 1, Thrasymachus makes the radical claim that being just is ‘high-minded simplicity’ and being unjust is ‘good judgment’ (348c–e). Because injustice involves benefiting oneself, while justice involves benefiting others, the unjust are wise and good and the just are foolish and bad (348d–e). The “greedy craftsperson” argument (1.349b–350c) attempts to show that the unjust person's desire to outdo or have more than ( pleon echein) everyone is a symptom of her ignorance. Many commentaries have found the argument problematic (...) and unclear. However, this paper argues that the greedy craftsperson argument defends plausible constraints on the nature of justice and wisdom. (shrink)

How do people survive under extreme conditions? Will selfish, non-cooperating free-rider types – the solo players – have the best chances of surviving? Or would cooperating, hard-working types – the team players – have higher chances? All morale put aside, it is interesting to know whether non-cooperation or cooperation pays off in a game characterized by scarcity and hard competition for survival. A study of people in such a Hobbesian state of nature can also teach us important lessons about (...) social dynamics in contemporary, prosperous societies. An interesting case of ‘The survival game’ can be found in Solzhenitsyn’s (1963 [1962]) self-biographical book, One Day in the Life of Ivan Denisovich, depicting life in a Soviet Gulag prison camp in Siberia January 1951. We use Solzhenitsyn’s work as evidence of the interplay between five player types among prisoners: Cooperative blind-riders (BRs), hard-riders (HRs) and tough-riders (TRs), i.e. the so-called ‘toilers’; non-cooperative easy-riders (ERs), looked upon by the toilers as ‘bastards’, ‘screws’ and ‘errand boys’; and finally Low-riders (LRs), comprising ‘goners’ and ‘jackals’. The main research question addresses the successfulness of the survival strategies of the five player types. Apart from a Multiple Player Approach (MPA) that may be seen as a further development of second-generation theory of collective action (Ostrom & Ahn, 2009), we apply Goffman’s (1959) dramaturgical theory on our case. Hence, we argue that impression management at two different ‘stages’ – the Brigade stage and the Camp stage – is crucial for survival for hard-riding as well as for easy-riding players, in particular strategic masking. Seeking to unite Goffman and game-theoretic MPA, our overall purpose is to make a theoretical contribution to “game-related sociology” (Swedberg, 2001). (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Working on the Clinton Administration's Health Care Reform Task ForceNancy Neveloff Dubler (bio)This narrative is based on my understanding of the elements of the Health Security Act that may have ethical implications. I have reconstructed these elements from my experience on the Health Care Reform Task Force and they are part of the health care plan that the President presented to Congress. (At the time this article went to (...) press, the actual legislation, which should answer my remaining specific questions more clearly, had not yet been released.) I perceive the most important features of the plan to be:• The legislation will create a "right" to health care for all citizens—access to care will be universal;• The plan will involve some form of managed competition in which groups of providers (called Approved or Accredited Health Plans (AHPs)) will offer comparable benefit packages at slightly (or widely) different costs;• The AHPs will negotiate with the Health Alliance (HA) to determine the price that they will charge their consumer-patients;• There will be open enrollment with no barriers to coverage, such as exclusions for pre-existing conditions;• Community rating will be in effect in different localities and enrolled persons in any AHP will pay the same premium;• The coverage for any enrolled person will be portable;• The overall structure will be a cooperative federal/state enterprise in which the states will have quite extensive abilities to fashion variations of the basic plan to meet their particular needs;• Primary care will be encouraged and incentives for physicians to train in primary care specialties provided;• Non-physician providers will be central to the functioning of the health care plans;• Efforts will be made to develop a "person power" pool so that people with an abstract "right" to health care will have real access to providers, in their localities, who can fulfill the promise that the right creates; [End Page 421]• The goal of cost containment will be central to the organization and regulation of the system;• Administrative simplicity and quality protections will be central.Co-chairing the Bioethics Working Group (BWG) of the White House Task Force on Health Care Reform was a unique experience. Approximately 40 Task Force working groups were established by Hillary Rodham Clinton, the President, and the senior Task Force staff. Various members of the President's office and other knowledgeable members of the Executive Branch selected the participants. In our group, appointments were made largely on the recommendations of the co-chairs. The BWG, among the last of the groups formed, carried the official name "The Working Group on the Ethical Foundations of the New System" and was jointly led by me and Marion Gray Secundy, a Professor of Bioethics at Howard University. The fact that the leadership of the Task Force saw fit to establish such a group, thereby confirming that bioethics is a player in the arena of health care policy, was in itself significant and was made no less so by the lack of clarity regarding the group's aims and goals.The working groups of the Task Force were organized into clusters, determined by the relatedness of the somewhat distinct, but always overlapping, content of their investigations. Separate clusters and working groups, for example, looked at mental health, long term care, and the benefit package and coverage for low-income and non-working families. On this last issue there was also a working group that explored health policy initiatives for underserved populations. This multiple focus on related issues proved to be an excellent method for ensuring that the complexity of these topics was sufficiently explored. There was a published schedule for when these groups met together, and members of other groups who had similar or overlapping concerns were invited to attend and to participate.Every week or so, all of the working groups reported to the Task Force leadership, under the direction of Ira Magaziner, in a process called a "tollgate." Prior to the tollgate, the working groups were required to submit formal written analyses of the problems they had most recently been considering. Copies of these documents were placed in a special room so that those who were interested could review... (shrink)

An insider's provocative account of one of the most contentious debates in science today When Niles Eldredge and Stephen Jay Gould, two of the world's leading evolutionary theorists, proposed a bold new theory of evolution—the theory of "punctuated equilibria"—they stood the standard interpretation of Darwin on its head. They also ignited a furious debate about the true nature of evolution. On the one side are the geneticists. They contend that evolution proceeds slowly but surely, driven by competition among (...) organisms to transmit their genes from generation to generation. On the other are the paleontologists, like Eldredge and Gould, who show in the fossil record that in fact evolution proceeds only sporadically. Long periods of no change—equilibria—are "punctuated" by episodes of rapid evolutionary activity. According to the paleontologists, this pattern shows that evolution is driven far more by environmental forces than by genetic competition. How can the prevailing views on evolution be so different? In Reinventing Darwin, Niles Eldredge offers a spirited account of the dispute and an impressive case for the paleontologists' side of the story. With the mastery that only a leading contributor to the debate can provide, he charts the course of theory from Darwin's day to the present and explores the fundamental mysteries and crucial questions that underlie the current quarrels. Is evolution fired by a gentle and persistent motor and fueled by the survival instincts of "selfish genes"? Or does it proceed in fits and starts, as the fossil record seems to show? What is the role of environmental changes such as habitat destruction and of cataclysmic events like meteor impacts? Are most species inherently stable, changing only very little until they succumb to extinction? Or are species highly adaptable, changing all the time? Eldredge sorts through the major findings and interpretations and presents a lively introduction to the leading edge of evolutionary theory today. Reinventing Darwin offers a rare insider's view of the sometimes contentious, but always stimulating work of scientific inquiry. PRAISE FOR NILES ELDREDGE'S PREVIOUS BOOKS The Miner's Canary: Unraveling the Mysteries of Extinction "The Miner's Canary rings with integrity. The author takes care to present opposing views.

In this paper, I will argue that Rawls’s duty of assistance offers an incomplete picture of our international social and economic responsibilities. I will start by presenting the two main interpretations of the ‘Rawlsian circumstances of egalitarian distributive justice’ – the first requiring the existence of a ‘certain kind’ of cooperation, the second the existence of a ‘certain kind’ of interaction with the will – and then show that none of them rules out the applicability of international principles of egalitarian (...) distributive justice. My argument will draw on societies’ participation in the World Trade Organisation (WTO). So, in the second section I will show that even though this organization is not endowed with a centralized coercive authority, its participants are asked to accept significant constraints on their behaviour and are therefore owed a special justification for these constraints. I will also suggest that the alleged voluntariness of this organization may not only be contested (especially when developing societies are involved), but may also not be sufficient to rule out requirements of distributive equality. In the third section, I will show that, as any system of cooperation, the WTO gives rise to requirements of fairness and that, given the purpose it claims to serve, not all inequalities that can be traced back to so-called ‘domestic’ factors can be considered justified. More specifically, I will argue that the fairness of the WTO requires that all its participants be given a fair chance of benefiting from global market competitions, and that this is likely to entail significant egalitarian distributive duties among societies.

This chapter provides an overview of the key European Union (EU) competition law provisions, focusing on their impact on the global economy and how this impact is managed. It considers the main transnational themes that arise. The first is the age‐old question of the extent to which national law applies across its borders. The second is the question of externalities, which has two ramifications. The first is an economic one, whereby the concern is that the enforcement of competition (...) law in one jurisdiction may have negative repercussions in others, reducing global welfare. The second branch is political in character and arises when the enforcement of competition law in one jurisdiction harms the economic interests of firms abroad. A third theme is collaboration among agencies in the context of global anticompetitive conduct. A fourth theme is hypocrisy. The chapter also sketches how competition policy became the European Union's first supranational policy. (shrink)

Introductory paper: Ethicists and political scientists are increasingly convinced that the moral legitimacy of political decisions is rooted in the quality of the social dialogue that precedes those decisions. A broad-based social consideration and discussion creates the form to examine and to refine options and visions and assures a general respect for commonly arrived decisions. In order to enable such consideration and discussion, it would seem essential that as many people and interest groups as possible be provided adequate information so (...) that they can proceed in a nuanced fashion in their discussions.Information on environment issues is often a complex of issues: genetic manipulation, atmospheric warming, and rising sea levels, for instance, often appear in highly technical and occasionally contradictory scientific reports. One cannot presume that the average citizen can make scientifically responsible judgements about these questions. It is not, however, just the complexity of issues that keeps the public debate about environmental questions in the shadow. There is a basic lack of interest among the general public about becoming technically informed about environmental issues. The popular media which as carefully as possible finesses its presentation about the issue, makes more room in its reporting for politicians fighting among themselves, crimes, scandals, and spectacular events.Issues based on well thought out argumentation are rarely reported. That does not mean that more people are growing concerned about the environment. In the insecurity that characterizes our post-modern existence, anxiety about the worsening environment is an important factor; but the result of this concern is not that there is more attentive reporting during news presentations but rather that startling conclusions are regularly announced or that spectacular protest actions are reported upon in every detail. What one often sees happening is that pressure groups, by arousing public emotion, try to influence the political agenda. Such emotional reactions are not the immediate result of a correct interpretation of the facts but are based rather on the fantastic images of one-liners or single events.What is the policy of Greenpeace in this regard, and especially in its campaigns about genetic manipulation? How do representatives of the agro-industry react to communications from Greenpeace? What do they propose as alternatives? How can one better communicate, in view of the breadth of public opinion, about environmental issues? How can a journalist, in the competitive world of the media, deliver objective information to the greatest number of people? How can the classic special interest groups, such as agricultural organizations, unions, cultural groups, and political parties truly contribute to quality dialogue about these questions? (shrink)

Some philosophers, most notably Julian Savulescu, have argued that potential parents have a moral reason to do what they can to have a child with the highest expected level of well-being.1 This is not just a reason to do what will make a particular child better off than he or she would otherwise be but also a reason to choose, from among different possible children, the one that has the highest expected well-being. The claim that potential parents have such (...) a reason is then often deployed as a premise in arguments in support of genetic enhancement. Robert Sparrow has argued in response that this claim implies that potential parents have a reason to choose to have female children only, primarily because women are genetically disposed to live, on average, 3–7 years longer than men.2 He takes this implication to be a reductio of this particular form of argument in support of human enhancement. In her paper, Sexual dimorphism and human enhancement, Paula Casal seeks to rebut Sparrow's argument and then goes on to suggest that a better case for the selection of female children could be made on grounds of moral enhancement, since women are far less genetically disposed to be violent and aggressive than men.3 Recognising, however, that the creation of only female children would lead to human extinction, she concludes that the way to achieve the best outcome would be to use techniques of genetic modification, should they become available, to make men more like women in certain respects: smaller, less aggressive, less competitive, less violent, less obsessed with sex, less prone to taking great risks, and less likely to die early from accident, combat, or disease.Like Larry Temkin, I am largely in agreement with Casal on these matters. In this short commentary, I …. (shrink)

Many evolutionary models assume that behaviors are caused directly by genes. An implication is that behavioral uniformity should be found only in groups that are genetically uniform. Yet, the members of human social groups often behave in a uniform fashion, despite the fact that they are genetically diverse. Behavioral uniformity can occur through a variety of psychological mechanisms and social processes, such as imitation, consensus decision making, or the imposition of social norms. We present a series of models in which (...) genes code for social transmission rules, which in turn govern the behaviors that are adopted. Transmission rules can evolve in randomly formed groups that concentrate phenotypic variation at the between-group level, favoring the evolution of altruistic behaviors and other group-advantageous traits. In addition, a direct bias toward adopting altruistic behaviors can evolve. Our models begin to show how group selection can be a strong force in human evolution, despite the absence of extreme genetic variation among groups. (shrink)
