We use tools from evolutionary game theory to examine how power might influence the cultural evolution of inequitable norms between discernible groups in a population of otherwise identical individuals. Similar extant models always assume that power is homogeneous across a social group. As such, these models fail to capture situations where individuals who are not themselves disempowered nonetheless end up disadvantaged in bargaining scenarios by dint of their social group membership. Thus, we assume that there is heterogeneity in the groups (...) in that some individuals are more powerful than others. Our model shows that even when most individuals in two discernible sub-groups are relevantly identical, powerful individuals can affect the social outcomes for their entire group; this results in power by association for their in-group and a bargaining disadvantage for their out-group. In addition, we observe scenarios like those described where individuals who are more powerful will get less in a bargaining scenario because a convention has emerged disadvantaging their social group.

Various results show the ‘formal equivalence’ of kin and group selectionist methodologies, but this does not preclude there being a real and useful distinction between kin and group selection processes. I distinguish individual- and population-centred approaches to drawing such a distinction, and I proceed to develop the latter. On the account I advance, the differences between kin and group selection are differences of degree in the structural properties of populations. A spatial metaphor provides a useful framework for thinking about these (...) differences: kin and group selection may be conceptualized as large, overlapping regions of K - G space. I then consider some implications of the account, defend it from possible objections, and further argue that the structural features characteristic of both kin and group selection may recur at multiple levels of biological organization.

Veissière et al. must sacrifice explanatory realism and precision in order to develop a unified formal model. Drawing on examples from cognitive archeology, we argue that this makes it difficult for them to derive the kinds of testable predictions that would allow them to resolve debates over the nature of human social cognition and cultural acquisition.

Na minha opinião, um comportamentoque eu é uma expressão de nossa psicologia evoluiu e tão intimamente relacionada à religião, moralidade e ética, se alguém sabe olhar para eles. -/- Muitos vão achar estranho que ele passe pouco tempo discutindo os temas comuns à maioria das discussões religiosas, mas na minha opinião é essencial primeiro entender as generalidades do comportamento e isso requer uma boa compreensão da biologia e psicologia que são principalmente notáveis por sua ausência em trabalhos sobre religião, política, (...) história, moral e ética, etc. Na minha opinião, a maioria desses esforços não tem nenhuma compreensão em todo o funcionamento do Sistema 2, as lentas funções cortical do cérebro que podem ser equiparadas ao comportamento linguístico ou à mente, e que eu chamo de Psicologia Descritivo do Pensamento da Ordem Superior e que considero ser o pro vince da filosofia no sentido estreito. -/- É minha afirmação que a tabela intencional (racionalidade, mente, pensamento, linguagem, personalidade, etc.) que apresenta com destaque aqui descreve com mais ou menos precisão, ou pelo menos serve como heurística, como pensamos e nos comportamos, e portanto não apenas engloba filosofia e psicologia, mas tudo mais (religião, história, literatura, matemática, política, etc.). Note especialmente que a intencionalidade e a racionalidade como eu (juntamente com Searle, Wittgenstein e outros) vejo, inclui tanto o sistema 2 de ações deliberativas conscientes quanto inconscientes ou reflexos do Sistema 1. -/- Essa coleção de artigos foi escrita nos últimos 10 anos e revisada para atualizá-los (2019). Todos os artigos são sobre comportamento humano (como todos os artigos de qualquer pessoa sobre qualquer coisa), e assim sobre as limitações de ter uma ancestralidade recente de macacos (8 milhões de anos ou muito menos dependendo do ponto de vista) e palavras e fatos manifestados no âmbito de nossa psicologia inata como apresentado na tabela da intencionalidade. Como diz o famoso evolucionista Richard Leakey, é essencial não notar que evoluímos dos macacos, mas que de todas as formas importantes, somos macacos. Se todos tivessem uma compreensão real disso (ou seja, ecologia humana e psicologia para dar-lhes algum controle sobre si mesmos), talvez a civilização teria uma chance. Como as coisas são, no entanto, os líderes da sociedade não têm mais compreensão das coisas do que seus eleitores e, portanto, o colapso na anarquia é inevitável é, apesar das visões quase universais de que religião, política ou tecnologia podem nos salvar. Veja minhas Ilusões Uuicidas tópicas noséculo 21 5 e d(2019), para uma exposição detalhada desta visão. -/- É essencial entender por que nos comportamos como nos comportamos e é por isso que começo com uma breve revisão da estrutura lógica da racionalidade, que fornece alguns heurísticos para a descrição da linguagem (mente, racionalidade, personalidade) e dá alguns sugestões sobre como isso se relaciona com a evolução do comportamento social. Isso se concentra nos dois escritores que encontrei o mais importante nesse sentido, Ludwig Wittgenstein e John Searle, cujas ideias eu combinei e extenso dentro da estrutura do sistema duplo (dois sistemas de pensamento) que provou ser tão útil no pensamento pesquisa recente e raciocínio. Como notei, na minha opinião há essencialmente uma sobreposição completa entre a filosofia, no sentido estrito de questões duradouras relativas à disciplina acadêmica, e à psicologia descritiva do pensamento de maior ordem (comportamento). Uma vez que se entendeu a ideia de Wittgenstein de que há apenas a questão de como o jogo de idiomas será jogado, as condições de satisfação (o que torna uma declaração verdadeira ou satisfeita, etc.) são determinadas e esse é o fim da discussão. Sem neurofisiologia, sem metafísica, sem pós-modernismo, sem teologia. -/- Junto com muitos, vejo isso como a questão religiosa ou moral básica de nossos tempos que os Estados Unidos e o mundo estão em processo de colapso por causa do crescimento excessivo da população, a maioria do século passado, e agora tudo, por causa do povo do Terceiro Mundo. O consumo de recursos e a adição de 3 bilhões a mais do que cerca de 2100 entrarão em colapso na civilização industrial e causarão fome, doença, violência e guerra em uma escala surpreendente. A terra perde pelo menos 1% de seu solo superior a cada ano, de modo que se aproxima de 2100, a maior parte de sua capacidade de cultivo de alimentos desaparecerá. Bilhões morrerão e a guerra nuclear é muito segura. Nos Estados Unidos, isso está sendo muito acelerado pela imigração em massa e reprodução de imigrantes, combinado com os abusos que tornam a democracia possível. A natureza humana depravada inexoravelmente transforma o sonho da democracia e da diversidade em um pesadelo de crime e pobreza. A China continuará a sobrecarregar os Estados Unidos e o mundo, desde que mantenha a ditadura que limita o egoísmo e permita o planejamento a longo prazo. A causa raiz do colapso é a incapacidade de nossa psicologia inata de se adaptar ao mundo moderno, levando as pessoas a tratar pessoas não relacionadas como tendo interesses comuns (o que eu sugiro pode ser considerado um não reconhecido - mas o mais comum e mais grave - problema psicológico - Transtorno de Aptidão Inclusiva). Isso, além da ignorância da biologia básica e da psicologia, leva aos delírios da engenharia social dos parcialmente educados que controlam as sociedades democráticas. Poucos entendem que se você ajuda uma pessoa, você prejudica outra pessoa, não há almoço grátis, e cada item que alguém consome destrói a terra além do reparo. Como resultado, as políticas sociais em todos os lugares são insustentáveis, e uma a uma todas as sociedades sem controles rigorosos sobre o egoísmo entrarão em colapso em anarquia ou ditadura. Sem mudanças dramáticas e imediatas, não há esperança de evitar o colapso dos Estados Unidos, ou qualquer país que prossiga com um sistema democrático, especialmente agora que os marxistas não marxistas do Terceiro Mundo Supremacistas estão assumindo o controle dos EUA e de outras democracias ocidentais, e ajudando os sete sociopatas que lideram a China a terem sucesso em seu plano de eliminar a paz e a liberdade e a religião em todo o mundo. Daí minha redação final es. É claro que é uma visão facilmente defensável que pesquisadores de Inteligência Artificial (também conhecidos como Estupidez Artificial ou Socipatia Artificial) são ainda mais maus do que os democratas e o PCC, e eu faço breves comentários sobre isso também. -/- Vários artigos tocam A Única Grande Ilusão Familiar Feliz, ou seja, que somos geneticamente selecionados para cooperar com todos, e que os ideais eufóricos da Democracia, Da Diversidade, Igualdade e Religião nos levarão à utopia, se apenas lidarmos com as coisas corretamente (a possibilidade da política). Mais uma vez, o Princípio do Almoço Não Livre deve nos alertar que não pode ser verdade, e vemos em toda a história e em todo o mundo contemporâneo, que sem controles rigorosos, egoísmo e estupidez ganham vantagem e logo destroem qualquer nação que abrace essas ilusões. Além disso, a mente do macaco desconta o futuro, por isso cooperamos na venda da herança de nossos descendentes para confortos temporais, agravando muito os problemas. -/- Eu descrevo versões dessa decepção (ou seja, somos basicamente "amigáveis" se forda uma chance) como aparece em alguns livros recentes sobre sociologia/biologia/economia. Mesmo o excelente "Behave" (2017) de Sapolsky abraça a política de esquerda e a seleção de grupos e abre espaço para uma discussão sobre se os humanos são inatamente violentos. Concluo com dois ensaiossobre a grande tragédia que está se desenrolando nos Estados Unidos e no mundo, que podem ser vistos como resultado direto de nossa psicologia evoluída manifestada como as maquinações inexoráveis do Sistema 1. Nossa psicologia eminentemente adaptativa e eugenia nas planícies da África por cerca de 6 milhões de anos, quando nos dividimos dos chimpanzés, até cerca de 50.000 anos atrás, quando muitos de nossos ancestrais deixaram a África (ou seja, no EEE ou no Ambiente de Adaptação Evolutiva), é agora a desadaptável e disgenicidade e fonte de nossos suicídios utópicos. Assim, como todas as discussões comportamentais (teologia, filosofia, psicologia, sociologia, biologia, antropologia, política, direito, literatura, história, economia, estratégias de futebol, reuniões de negócios, etc.), este livro trata de estratégias evolutivas, genes egoístas e fitness inclusivo (seleção de parentesco, seleção natural), embora, claro, poucos entendam isso, independentemente de serem acadêmicos ou camponeses, ateus ou fundamentalistas.

Kin selection and group selection were once seen as competing explanatory hypotheses but now tend to be seen as equivalent ways of describing the same basic idea. Yet this ‘equivalence thesis’ seems not to have brought proponents of kin selection and group selection any closer together. This may be because the equivalence thesis merely shows the equivalence of two statistical formalisms without saying anything about causality. W.D. Hamilton was the first to derive an equivalence result of this type. Yet Hamilton (...) was aware of its limitations, and saw that, while illuminating, it papered over some biologically important distinctions. Attending to these distinctions leads to the concept of ‘K-G space’, which helps us see where the biological disagreements between proponents of kin selection and group selection really lie.

I distinguish two roles for a fitness concept in the context of explaining cumulative adaptive evolution: fitness as a predictor of gene frequency change, and fitness as a criterion for phenotypic improvement. Critics of inclusive fitness argue, correctly, that it is not an ideal fitness concept for the purpose of predicting gene-frequency change, since it relies on assumptions about the causal structure of social interaction that are unlikely to be exactly true in real populations, and that hold as approximations only (...) given a specific type of weak selection. However, Hamilton took this type of weak selection, on independent grounds, to be responsible for cumulative assembly of complex adaptations. In this special context, I argue that inclusive fitness is distinctively valuable as a criterion for improvement and a standard for optimality. Yet to call inclusive fitness a criterion for improvement and a standard for optimality is not to make any claim about the frequency with which inclusive fitness optimization actually occurs in nature. This is an empirical question that cannot be settled by theory alone. I close with some reflections on the place of inclusive fitness in the long running clash between ‘causalist’ and ‘statisticalist’ conceptions of fitness. (shrink)

In this essay review of Samir Okasha's Agents and Goals in Evolution, I reflect on the rationale for agential thinking in biology, and consider whether the rationale is the same for genes as for organisms. I also discuss Okasha's ingenious examples of the evolution of irrational behaviour, and in particular the evolution of violations of the "independence axiom" of rational choice theory. These examples rely on a crucial distinction between aggregate and idiosyncratic risk.

After biologist Deborah Gordon made a series of experimental discoveries in the 1980s, she argued that a change in terminology regarding the division of labor among castes of specialists was needed. Gordon’s investigations of the interactive effects of ants in colonies led her to believe that the established approach Edward O. Wilson had pioneered was biased in a way that made some alternative candidate adaptive explanations invisible. Gordon argued that this was because the term “division of labor” implied a division (...) among specialists that was unwarranted, and proposed “task allocation” as a better description that did not bias research against the alternative causes she had discovered. Gordon’s empirical findings and theoretical proposals also vindicate the initial critics of Wilson’s human sociobiology who have been dismissed as political radicals, but her proposals have been widely misunderstood by many contemporary behavioral ecologists. The terminological and methodological confusions rampant in contemporary discourse can be clarified by applying a framework developed by Elisabeth Lloyd involving an analysis of the constraints imposed by different research questions. Applying this framework will show how the methodological problems involving description raised by the initial critics of Wilson’s human sociobiology extended to his analysis of ants, indicating that they were not challenging Wilson’s naturalistic approach to the study of human evolution, but rather his methods. It will also show how confusion over how Gordon’s proposed research questions have been conflated with the possible answers she has argued ought to be investigated. This in turn will clarify contemporary disputes over her proposal to abandon the term “division of labor.”. (shrink)

The role of genetic relatedness in social evolution has recently come under critical attention. These arguments are here critically analyzed, both theoretically and empirically. It is argued that when the conceptual structure of the theory of natural selection is carefully taken into account, genetic relatedness can be seen to play an indispensable role in the evolution of both facultative and advanced eusociality. Although reviewing the empirical evidence concerning the evolution of eusociality reveals that relatedness does not play a role in (...) the initial appearance of helper phenotypes, this follows simply from the fact that natural selection – of which relatedness is a necessary component – does not play a causal role in the origin of any traits. Further, separating two logically distinct elements of causal explanation – necessity and sufficiency – explains why the debate lingers on: although relatedness plays a necessary role in the evolution of helping and advanced eusociality, relatedness alone is not sufficient for their appearance. Therefore, if the relatedness variable in a given data set is held at a uniformly high value, then it indeed may turn out that other factors occupy a more prominent role. However, this does not change the fact that high relatedness functions as a necessary background condition for the evolution of advanced eusociality. (shrink)

The kin selection theory has recently been criticised on the basis of claiming that genetic relatedness does not play a causal role in the social evolution among individuals of insect societies. We outline here a line of criticism of this view by demonstrating two things. First, there are strong conceptual, theoretical and empirical reasons to think that close genetic relatedness has been necessary for the rise of the helper castes of social insects. And second, once we understand how causal explanation (...) itself results from an interplay of two logically distinct elements, necessity and sufficiency, we can also understand the scenarios in which relatedness does not seem to play a causal role for evolution of helper castes. The result of this analysis is that we should be more careful about the way we frame the empirical data on the evolution of social behaviour. (shrink)

-/- Esta es una excelente revisión de las interacciones gen/ambiente en el comportamiento y, a pesar de ser un poco anticuado, es una lectura fácil y valiosa. Empiezan con estudios gemelos que muestran el impacto abrumador de la genética en el comportamiento. Señalan los estudios cada vez más conocidos de Judith Harris, que amplían y resumen los hechos de que el ambiente doméstico compartido casi no tiene efecto sobre el comportamiento y que los niños adoptados crecen para ser tan diferentes (...) de sus hermanastros y hermanas como las personas elegidas al azar. Un punto básico que ellos (y casi todos los que discuten sobre la genética conductual) no se dan cuenta es que los cientos (miles dependiendo de su punto de vista) de los universales de comportamiento humano, incluyendo todos los fundamentos de nuestras personalidades, son 100% determinado por nuestros genes, con no hay variación en las normales. Todo el mundo ve un árbol como un árbol y no una piedra, busca y come comida, se enfada y celosa, etc. Por lo tanto, lo que están hablando sobre todo aquí es cuánto ambiente (cultura) puede afectar al grado en que se muestran varios rasgos, en lugar de su apariencia. -/- Por último, discuten la eugenesia en la costumbre políticamente correcta, al no notar que nosotros y todos los organismos somos los productos de la eugenesia de la naturaleza y que los intentos de derrotar la selección natural con la medicina, la agricultura y la civilización en su conjunto, son desastroso para cualquier sociedad que persiste en hacer esto. Tanto como el 50% de todas las concepciones, o unos 100 millones/año, terminan en abortos espontáneos tempranos, casi todos sin que la madre sea consciente. Este sacrificio natural de genes defectuosos impulsa la evolución, nos mantiene relativamente genéticamente sólidas y hace posible la sociedad. La disgenesia es suficiente para destruir la civilización pero sobrepoblación se do primero. -/- Aquellos que deseen un marco completo hasta la fecha para el comportamiento humano de la moderna Dos Sistemas Punto de Vista puede consultar mi libro 'La estructura lógica de la filosofía, la psicología, la mente y lenguaje En Ludwig Wittgenstein y John Searle ' 2Nd Ed (2019).

A recent dispute between Richard Dawkins and Edward O. Wilson concerning fundamental concepts in sociobiology is examined. It is argued that sociobiology has not fared well since the 1970s, and that its survival as a ‘scientific’ perspective has been increasingly tenuous. This is, at least in part, because it has failed to move forward in the ways its developers anticipated, but also because it has not seen the developments in natural history, genomics and social science it was relying upon. It (...) is argued that sociobiology has become a purely utilitarian perspective, a way of looking at things, reliant increasingly on studies of the behaviour of social insects for its scientific credentials. The dispute between Dawkins and Wilson is then reconsidered in this light, and it is argued that – regardless of which position prevails – sociobiology’s parlous state as a means of explaining action is now difficult to disguise.

Debates about human nature inform every philosophical tradition from their inception (see Stevenson 2000 for many examples). Evolutionarily based criticisms of human nature are of much more recent origin. Ironically, most evolutionarily based criticisms of human nature are directed at work whose avowed goal is to biologicize human nature and even to place human nature within an evolutionary frame. Here I will focus on accounts of human nature that begin with and come after E.O. Wilson’s sociobiology. I will also focus (...) on criticisms of human nature that arose first as responses to sociobiology. There are some more recent approaches to human nature that have much in common with the sociobiological approach and I will show that critical arguments developed to target sociobiology have purchase on related recent approaches to human nature. In what follows I will briefly outline some well-known accounts of human nature. Next I will briefly outline some key evolutionarily based arguments against such accounts of human nature. I conclude by summarizing the evolutionary case against biological accounts of human nature and endorsing it. (shrink)

Is cultural evolution needed to explain altruistic selfsacrifice? Some contend that cultural traits (e.g. beliefs, behaviors, and for some “memes”) replicate according to selection processes that have “floated free” from biology. One test case is the example of suicide kamikaze attacks in wartime Japan. Standard biological mechanisms—such as reciprocal altruism and kin selection—might not seem to apply here: The suicide pilots did not act on the expectation that others would reciprocate, and they were supposedly sacrificing themselves for country and emperor, (...) not close relatives. Yet an examination of both the historical record and the demands of evolutionary theory suggest the kamikaze phenomenon does not cry out for explanation in terms of a special non-biological selection process. This weakens the case for cultural evolution, and has interesting implications for our understanding of altruistic self-sacrifice. (shrink)

This paper attempts to reconcile critics and defenders of inclusive fitness by constructing a synthesis that does justice to the insights of both. I argue that criticisms of the regression-based version of Hamilton’s rule, although they undermine its use for predictive purposes, do not undermine its use as an organizing framework for social evolution research. I argue that the assumptions underlying the concept of inclusive fitness, conceived as a causal property of an individual organism, are unlikely to be exactly true (...) in real populations, but they are approximately true given a specific type of weak selection that Hamilton took, on independent grounds, to be responsible for the cumulative assembly of complex adaptation. Finally, I reflect on the uses and limitations of “design thinking” in social evolution research. The debate about the foundations of inclusive fitness theory that has followed in the wake of Nowak, Tarnita and Wilson’s critique has been remarkably polarizing. After several rounds of rebuttals and replies, there is still little evidence of any serious reconciliation between the theory’s critics and its defenders. It doesn’t have to be this way. I believe that, on the main points of disagreement, it is possible to find a way forward that does justice to the insights of both camps. My aim in this paper is to find that way forward. (shrink)

From mitochondria to meerkats, the natural world is full of spectacular examples of social behaviour. In the early 1960s W. D. Hamilton changed the way we think about how such behaviour evolves. He introduced three key innovations - now known as Hamilton's rule, kin selection, and inclusive fitness - and his pioneering work kick-started a research program now known as social evolution theory. This is a book about the philosophical foundations and future prospects of that program.

Although classical evolutionary theory, i.e., population genetics and the Modern Synthesis, was already implicitly ‘gene-centred’, the organism was, in practice, still generally regarded as the individual unit of which a population is composed. The gene-centred approach to evolution only reached a logical conclusion with the advent of the gene-selectionist or gene’s eye view in the 1960s and 1970s. Whereas classical evolutionary theory can only work with fitness differences between individual organisms, gene-selectionism is capable of working with fitness differences among genes (...) within the same organism and genome. Here, we explore the explanatory potential of ‘intra-organismic’ and ‘intra-genomic’ gene-selectionism, i.e., of a behavioural-ecological ‘gene’s eye view’ on genetic, genomic and organismal evolution. First, we give a general outline of the framework and how it complements the—to some extent—still ‘organism-centred’ approach of classical evolutionary theory. Secondly, we give a more in-depth assessment of its explanatory potential for biological evolution, i.e., for Darwin’s ‘common descent with modification’ or, more specifically, for ‘historical continuity or homology with modular evolutionary change’ as it has been studied by evolutionary developmental biology during the last few decades. In contrast with classical evolutionary theory, evo-devo focuses on ‘within-organism’ developmental processes. Given the capacity of gene-selectionism to adopt an intra-organismal gene’s eye view, we outline the relevance of the latter model for evo-devo. Overall, we aim for the conceptual integration between the gene’s eye view on the one hand, and more organism-centred evolutionary models on the other. (shrink)

The co-evolutionary concept of tri-modal stable evolutionary strategy (SESH) 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 others ones. Resulting volume of both parameters define the vectors of 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. The mechanism of influence of each module on the evolution of the two remaining modules of SESH a priori can be twofold: (1) informational co-evolution (direct selective pressure); (2) semantic co-evolution (time-varying semantic code, the compliance of the biological, socio- cultural and techno-rationalist adaptive modules of human stable evolutionary strategy). More rapidly evolving autonomous element of the co-evolutionary pair becomes making sense factor for the partner. Semantic co-evolution is the discrete acquisition of adaptive significance of individual alleles by changing socio-cultural types, manifested as an increase in the genetic variability of populations of Homo sapiens, and domesticated species parallel to socio-culturogenesis. The socio- cultural landscape leads to drastically difference of direction in biological evolution of Atlantic and East-Slavic ethnicities/civilizations. (shrink)

In this paper I argue the best examples of the methods in the evolutionary social sciences don’t actually resemble either of the two methods called “Adaptive Thinking” or “Reverse Engineering” described by evolutionary psychologists. Both AT and RE have significant problems. Instead, the best adaptationist work in the ESSs seems to be based on and is aiming at a different method that avoids the problems of AT and RE: it is a behavioral level method that starts with information about both (...) the trait in question and knowledge of the EEA. I describe some examples from the literature, and suggest how a behavioral level ESS might still contribute to the discovery and understanding of human psychology. Finally, I describe some remaining problems for adaptationist reasoning of this kind. (shrink)

The understanding of value in moral naturalism as a descriptivist endeavor will be analized through an application of the naturalistic fallacy on an evolutive perspective of moral psychology. From a brief analysis of the naturalistic fallacy as proposed by Dall’Agnol, I’ll criticize the author’s application of such on what he refers to as moral naturalism. Contrasting E. Wilson’s sociobiology with R. Triver’s theory of reciprocal altruism I will procure a definition of naturalized ethics by investigating the psychological roots of moral (...) motivation. Once identified the descriptive and non-reductionist aspects of contemporary moral naturalism, the naturalistic fallacy presents itself as unbecoming of its hallmark and metaethical importance, and it becomes clear that a naturalized comprehension of human moral behavior is vital to the understanding of the motivations for action and the conception of value; though weak under a normative perspective.

This article revisits the left-wing response to sociobiology in the 1970s and 1980s by examining the sociobiology debate in Finland in a larger European context. It argues that the Finnish academic left’s response to sociobiology represents a “third way” alongside the purely negative, often Marxist denial of biology’s relevance, which characterized the left’s response to sociobiology in many European countries such as Hungary and Sweden, and alongside the disregard that sociobiology confronted in most parts of Eastern Europe, as well as (...) in Germany. In the context of the last great political conflict of the Cold War in Europe, the controversy over the American “Euromissiles” in 1979–1983, the Finnish academic left challenged the allegedly fatalistic sociobiological aggression and war theories with an alternative biological language, turning the increasing enthusiasm over evolutionary ideas into a pacifist cause. Using leftist and pacifist forums to inform citizens and politicians of such biologically evolved human characteristics as mutual care and sociability, the Finnish critics of sociobiology wished to boost the public spirit, and to rationalize the pacifist ideal of the European-wide popular movement against nuclear weapons and militarism. As a result, the academic leftists in Finland revived the early twentieth-century tradition of “peace biology.” A proper understanding of this development calls for an analysis that acknowledges Finland’s special geopolitical and cultural position in the Cold War world between East and West.

Somewhere in the mists of the past, we somehow picked up the idea of an afterlife from our culture. So, where did this idea come from in the first place? The problem is not that there aren’t any plausible theories to explain it; the problem is that there are too many. Some claim that the belief in an afterlife is wishful thinking; others that it’s a way of encouraging socially desirable behavior; and others still that it represents ancient people’s best (...) effort to explain strange phenomena such as dreams. More recently, it has been suggested that afterlife beliefs are the handiwork of evolution by natural selection, or byproducts of various evolved psychological capacities. According to one approach, afterlife beliefs are products of natural selection, but not natural selection operating on genes or any other biological entities. Instead, afterlife beliefs are products of natural selection operating among ideas or memes. -/- 1.

In an incendiary 2010 Nature article, M. A. Nowak, C. E. Tarnita, and E. O. Wilson present a savage critique of the best-known and most widely used framework for the study of social evolution, W. D. Hamilton’s theory of kin selection. More than a hundred biologists have since rallied to the theory’s defence, but Nowak et al. maintain that their arguments ‘stand unrefuted’. Here I consider the most contentious claim Nowak et al. defend: that Hamilton’s rule, the core explanatory principle (...) of kin selection theory, ‘almost never holds’. I first distinguish two versions of Hamilton’s rule in contemporary theory: a special version (HRS) that requires restrictive assumptions, and a general version (HRG) that does not. I then show that Nowak et al. are most charitably construed as arguing that HRS almost never holds, while HRG buys its generality at the expense of explanatory power. While their arguments against HRS are fairly uncontroversial, their arguments against HRG are more contentious, yet these have been largely overlooked in the ensuing furore. I consider the arguments for and against the explanatory value of HRG, with a view to assessing what exactly is at stake in the debate. I suggest that the debate hinges on issues concerning the causal interpretability of regression coefficients, and concerning the explanatory function Hamilton’s rule is intended to serve. (shrink)

The theories of inclusive fitness and multilevel selection provide alternative perspectives on social evolution. The question of whether these perspectives are of equal generality remains a divisive issue. In an analysis based on the Price equation, Queller argued (by means of a principle he called the separation condition) that the two approaches are subject to the same limitations, arising from their fundamentally quantitative-genetical character. Recently, van Veelen et al. have challenged Queller’s results, using this as the basis for a broader (...) critique of the Price equation, the separation condition, and the very notion of inclusive fitness. Here we show that the van Veelen et al. model, when analyzed in the way Queller intended, confirms rather than refutes his original conclusions. We thereby confirm (i) that Queller’s separation condition remains a legitimate theoretical principle and (ii) that the standard inclusive fitness and multilevel approaches are indeed subject to the same limitations.

Phenomena like meat sharing in hunter-gatherers, altruistic self-sacrifice in intergroup conflicts, and contribution to the production of public goods in laboratory experiments have led to the development of numerous theories trying to explain human prosocial preferences and behavior. Many of these focus on direct and indirect reciprocity, assortment, or (cultural) group selection. Here, I investigate analytically how genetic relatedness changes the incentive structure of that paradigmatic game which is conventionally used to model and experimentally investigate collective action problems: the public (...) goods game. Using data on contemporary hunter-gatherer societies I then estimate a threshold value determining when biological altruism turns into maximizing inclusive fitness in this game. I find that, on average, contributing no less than about 40% of individual fitness to public goods production still is an optimal strategy from an inclusive fitness perspective under plausible socio-ecological conditions.

Building on and partially refining previous theoretical work, this paper presents an extended simulation model of ancestral warfare. This model (1) disentangles attack and defense, (2) tries to differentiate more strictly between selfish and altruistic efforts during war, (3) incorporates risk aversion and deterrence, and (4) pays special attention to the role of brutality. Modeling refinements and simulation results yield a differentiated picture of possible evolutionary dynamics. The main observations are: (i) Altruism in this model is more likely to evolve (...) for defenses than for attacks. (ii) Risk aversion, deterrence and the interplay of migration levels and brutality can change evolutionary dynamics substantially. (iii) Unexpectedly, one occasional simulation outcome is a dynamically stable state of ‘tolerated intergroup theft’, raising the question if corresponding patterns also exist in real intergroup conflicts. Finally, possible implications for theories of the co-evolution of bellicosity and altruism in humans are discussed. (shrink)

En este artículo se hace una crítica de los enfoques teóricos, aquí llamados por analogía o analógicos, que pretenden abstraer conceptos darwinistas del sustrato biológico para aplicarlos a dominios ontológicos (parcialmente) distintos, estrategia adoptada por versiones de la epistemología evolutiva y, sobre todo, por la teoría memética. Para ello se utiliza el argumento de la exclusión causal, tomado en préstamo de la filosofía de la mente; se hace evidente la existencia de un paralelismo entre causalidad mental y memética, y se (...) muestra cómo cualquier posible caracterización de la segunda a partir de la primera conduce a graves problemas metafísicos y epistemológicos. En las conclusiones se esbozan, sin intención de exhaustividad, algunas ideas sobre cómo evitar posiciones reduccionistas sin adoptar una postura teórica analógica. The main purpose of this paper is criticize theoretical approaches -here called by analogy, or analogical- which aim to extract Darwinian concepts from a biological substrate to apply them to (partially) different ontological domains. This strategy is adopted by some versions of evolutionary epistemology and, especially, by memetics theory. An argument borrowed from philosophy of mind, namely, the argument of causal exclusion, is used to carry out the critique. The existence of a parallelism between memetics and mental causation will be shown, and it will be argued that any possible characterization of the first in terms of the second implies serious metaphysical and epistemological problems. In the conclusions, with no intention of completeness, some ideas on how to avoid reductionist positions, without taking an analogical posture, will be outlined. (shrink)

Evolution and Rationality marks the end of a three-year project, ‘Evolution, Cooperation, and Rationality’, directed at the University of Bristol by the book’s editors, Samir Okasha and Ken Binmore. The collection draws together the editors’ pick of the papers delivered at the conferences the project hosted, and covers a wide range of topics at the intersection of evolutionary theory and the social sciences. It is a splendid anthology: timely, interdisciplinary, thematically cohesive, and full of substantive and interesting disagreements between the (...) contributors. (shrink)

This PhD dissertation examines the conceptual and theoretical foundations of the most general and most widely used framework for understanding social evolution, W. D. Hamilton's theory of kin selection. While the core idea is intuitive enough (when organisms share genes, they sometimes have an evolutionary incentive to help one another), its apparent simplicity masks a host of conceptual subtleties, and the theory has proved a perennial source of controversy in evolutionary biology. To move towards a resolution of these controversies, we (...) need a careful and rigorous analysis of the philosophical foundations of the theory. My aim in this work is to provide such an analysis. I begin with an examination of the concepts behavioural ecologists employ to describe and classify types of social behaviour. I stress the need to distinguish concepts that are often conflated: for example, we need to distinguish simple cooperation from collaboration in collective tasks, behaviours from strategies, and control from manipulation and coercion. I proceed from here to the formal representation of kin selection via George R. Price’s covariance selection mathematics. I address a number of interpretative issues the Price formalism raises, including the vexed question of whether kin selection theory is ‘formally equivalent’ to multi-level selection theory. In the second half of the dissertation, I assess the uses and limits of Hamilton’s rule for the evolution of social behaviour; I provide a precise statement of the conditions under which the rival neighbour-modulated fitness and inclusive fitness approaches in contemporary kin selection theory are equivalent (and describe cases in which they are not); and I criticize recent formal attempts to establish the controversial claim that kin selection leads to organisms behaving as if maximizing their inclusive fitness.

Although Darwinian concepts have largely been banned from the social sciences of the last century, they have recently seen a revival in several disciplines such as sociology, anthropology, or economics. Most of the current proponents of evolutionary theorizing in the social sciences avoid references to the older literature on social evolution. On that background, this article presents a contribution to Darwinist thinking in early American sociology that has mainly been overlooked in the literature. As the leading figure of the Human (...) Ecology Approach, which was established during the 1920s and 1930s, Robert Ezra Park drew heavily on evolutionary concepts to explain human evolution. A systematic presentation of these concepts in the light of the modern discussion on sociocultural evolution is given, followed by a conclusion about what can be learned from Park today. (shrink)

Inclusive fitness theory was not originally designed to explain the major transitions in evolution, but there is a growing consensus that it has the resources to do so. My aim in this paper is to highlight, in a constructive spirit, the puzzles and challenges that remain. I first consider the distinctive aspects of the cooperative interactions we see within the most complex social groups in nature: multicellular organisms and eusocial insect colonies. I then focus on one aspect in particular: the (...) extreme redundancy these societies exhibit. I argue that extreme redundancy poses a distinctive explanatory puzzle for inclusive fitness theory, and I offer a potential solution which casts coercion as the key enabler. I suggest that the general moral to draw from the case is one of guarded optimism: while inclusive fitness is a powerful tool for understanding evolutionary transitions, it must be integrated within a broader framework that recognizes the distinctive problems such transitions present and the distinctive mechanisms by which these problems may be overcome.

Andrew Bourke’s Principles of Social Evolution identifies three stages that characterize an evolutionary transition in individuality and deploys inclusive fitness theory to explain each stage. The third stage, social group transformation, has hitherto received relatively little attention from inclusive fitness theorists. In this review, I first discuss Bourke’s “virtual dominance” hypothesis for the evolution of the germ line. I then contrast Bourke’s inclusive fitness approach to the major transitions with the multi-level approach developed by Richard Michod, Samir Okasha and others. (...) I suggest that, rather than choosing between these approaches, we should exploit the strengths of both. Finally, I stress the need for a firmer conceptual grasp of the nature of social group transformation. (shrink)

It is commonly suggested that evolutionary considerations generate an epistemological challenge for moral realism. At first approximation, the challenge for the moral realist is to explain our having many true moral beliefs, given that those beliefs are the products of evolutionary forces that would be indifferent to the moral truth. An important question surrounding this challenge is the extent to which it generalizes. In particular, it is of interest whether the Evolutionary Challenge for moral realism is equally a challenge for (...) mathematical realism. It is widely thought not to be. In this paper, I argue that the Evolutionary Challenge for moral realism is equally a challenge for mathematical realism. Along the way, I substantially clarify the Evolutionary Challenge, discuss its relation to more familiar epistemological challenges, and broach the problem of moral disagreement. The paper should be of interest to ethicists because it places pressure on anyone who rejects moral realism on the basis of the Evolutionary Challenge to reject mathematical realism as well. And the paper should be of interest to philosophers of mathematics because it presents a new epistemological challenge for mathematical realism that bears, I argue, no simple relation to Paul Benacerraf's familiar challenge.

The essay explores the development of sociobiology, its basic tenets, and its contributions to the study of human nature as well as ethics. It insists that Darwinism is more than a biological theory and presents a possibility of interpreting sociobiology as manifesting not the triumph of the selfish gene but, on the contrary, the only way in which the expansion of altruism was possible.

In the years leading up to the Second World War the ethologists Konrad Lorenz and Nikolaas Tinbergen, created the tradition of rigorous, Darwinian research on animal behavior that developed into modern behavioral ecology. At first glance, research on specifically human behavior seems to exhibit greater discontinuity that research on animal behavior in general. The 'human ethology' of the 1960s appears to have been replaced in the early 1970s by a new approach called ‘sociobiology’. Sociobiology in its turn appears to have (...) been replaced by an approach calling itself Evolutionary Psychology. Closer examination, however, reveals a great deal of continuity between these schools. At present, whilst Evolutionary Psychology is the most visible form of evolutionary psychology, empirical and theoretical research on the evolution of mind and behavior is marked by a diversity of ideas and approaches and it is far from clear which direction(s) the field will take in future.

Niche construction theory can be applied to examine the influence of culturally constructed learning environments on the acquisition and retention of beliefs, values, role expectations, and skills. Thus, NCT provides a quantitative framework to account for cultural-historical contingency affecting development and cultural evolution. Learning in a culturally constructed environment is of central concern to many sociologists, cognitive scientists, and sociocultural anthropologists, albeit often from different perspectives. This article summarizes four pertinent theories from these fields—situated learning, activity theory, practice theory, and (...) distributed cognition. As a basis for interdisciplinary investigation, the article considers how these theories may be addressed using a cultural niche-construction framework, including the utility of an embedded model that explicitly accounts for effects of the constructed learning environment on within-individual learning dynamics in an evolutionary framework.

Essay Review of The Tragic Sense of Life: Ernst Haeckel and the Struggle over Evolutionary Thought by Robert J. Richards [2009].

Humans have developed the capacity to approve or disapprove of the behavior of their children and of unrelated individuals. The ability to approve or disapprove transformed social learning into a system of cumulative cultural inheritance, because it increased the reliability of cultural transmission. Moreover, people can transmit their behavioral experiences (regarding what can and cannot be done) to their offspring, thereby avoiding the costs of a laborious, and sometimes dangerous, evaluation of different cultural alternatives. Our thesis is that, during ontogeny, (...) the evaluative communication (approval/disapproval) between parents and offspring is substituted by other evaluative communications among peers, like individuals of the same generation. Each person belongs to a reference social group with individuals that interact more intensively. Humans have developed psychological mechanisms that enable cultural transmission by being receptive to parental advice as well as their reference social group. The selective pressure that promoted these new evaluative interactions arose to facilitate the establishment of efficient cooperative relationships. In short, the social control of behavior is essential to understand human cultural transmission. (shrink)

The object of study of the present is the critical reception of sociobiology and reflections on the sociobiology debate by one of Portugal's most notorious evolutionary thinkers, Germano da Fonseca Sacarrão (1914-1992). Our work starts with an extensive analysis of the vast literature concerning the emergence of sociobiology, the main criticisms it received, and the intense discussions (in and out of the academic circle) surrounding the new discipline's premises, framework, methodology, and ambitions, that took place in the years following the (...) publication of Edward O. Wihon's book Sociobiology: The New Synthesis in 1975, Germano da Fonseca Sacarrão addressed the emergence of sociobiology and the debate surrounding the new discipline in his writings as early as 1977, and once again in 1980. But in 1982, the Professor of Zoology and Anthropology at the University of Lisbon would devote an entire book to the issue: "A Biologia do Egoísmo -herança biológica de que o homem seria prisioneiro" (Biology of Selfishness. Biological inheritance that man would be a prisoner to). Sacarrão took the side of the critics, joining his voice to all of the main objections raised against sociobiology. Himself ideologically tuned to the left, he believed that the implications could extend much further, they could easily be used by extreme-right politicians to justify many of their views, for example, by contributing to legitimize certain practices such as male domination, warfare, xenophobia or racism.

Is it possible to be a socio-biologist and a feminist? Socio-biology has been accused of being a macho ideological arsenal, which seems to exclude in advance any possibility of amending it. However that was the project of several female researchers (in particular S. B. Hrdy and P. A. Gowaty), who suggested adopting the science’s theoretical framework in order to change it from within. This has been expressed in a change of focus: an appeal to take account of female strategies and (...) their evolution as well as the "sex war" at work in process of reproduction. This opening out of socio-biology’s theoretical framework has not been undertaken in the name of the privilege of a "female perspective" but it has without a doubt been nourished by the researchers’ marginal position in their discipline as well as their political involvement. "Male" contributions, such as W. G. Eberhard’s work on the "female’s cryptic choice", are also part of this movement though they do not claim allegiance to it. Similarly, a critical study has been carried out on the vocabulary of socio-biology: not in order to exercise a "politically correct" ideological tyranny but to improve the efficiency of the conceptual tools introduced by the science. Today some feminists think feminism should incorporate socio-biology’s results but resistance still remains strong. Though many feminists think feminism has more to bring to biology than the reverse, many biologists consider that feminism is just an ideology that should remain apart from scientific work. (shrink)
