Adaptationist accounts of morality attempt to explain the evolution of morality in terms of the selective advantage that judging in moral terms secured for our ancestors (e.g. Ruse 1998; Joyce 2006; Street 2006). So-called by-product explanations of morality have been presented as an alternative to adaptationist accounts (e.g. Prinz 2009; Ayala 2010; cf. Darwin 2004/1871). In assessing the relationship between adaptationist and by-product accounts, care must be taken to distinguish several related but importantly different notions: innateness, adaptation, exaptation, spandrel, and (...) by-product.

It is often thought that if an adaptationist explanation of some behavioural phenomenon is true, then this fact shows that a culturist explanation of the very same phenomenon is false, or else the adaptationist explanation preempts or crowds out the culturist explanation in some way. This chapter shows why this so-called competition thesis is misguided. Two evolutionary models are identified — the Information Learning Model and the Strategic Learning Model — which show that adaptationist reasoning can help explain why cultural (...) learning evolved. These models suggest that there will typically be a division of labor between adaptationist and culturist explanations. It is then shown that the Strategic Learning Model, which has been widely neglected by adaptationist thinkers, has important and underappreciated implications for a question that has long been contentious in the behavioural sciences — the question of the malleability of human nature.

Despite the burgeoning interest in new and more complex accounts of the organism-environment dyad by biologists and philosophers, little attention has been paid in the resulting discussions to the history of these ideas and to their deployment in disciplines outside biology—especially in the social sciences. Even in biology and philosophy, there is a lack of detailed conceptual models of the organism-environment relationship. This volume is designed to fill these lacunae by providing the first multidisciplinary discussion of the topic of organism-environment (...) interaction. It brings together scholars from history, philosophy, psychology, anthropology, medicine, and biology to discuss the common focus of their work: entangled life, or the complex interaction of organisms and environments.

یکی از صفات مهم و متمایزکنندۀ انسان نسبت به پستان‌داران نخستین، به لحاظ زیستی-تکاملی، فرهنگ است که نهادهای سیاسی و اجتماعی، سنت‌های دینی و اخلاقی را در بر می‌گیرد. بنا بر مطالعات زیستی-ژنتیکی، ادیان به عنوان یک فرهنگ جهان‌شمول از میزان ارث‌پذیری بالایی برخوردارند، به طوری که خصیصهٔ دین‌داری از نسل میان‌سال به نسل جوان‌تر به ارث می‌رسد. دیوید ویلسون زیست‌شناس آمریکایی، دین را یک «تطابق چندسطحی» و محصول تکامل فرهنگی می‌داند که در جهت مشارکت و ایجاد همبستگی بین گروه‌ها (...) شکل گرفته و آنچه باعث بقای ادیان در طول تاریخ و تنوع و تکثر آن در فرهنگ‌های مختلف بوده کارکرد تکاملی آنها در جهت همبستگی گروه‌های دینی بر مبنای واقع‌گرایی عملی است. در نظر ویلسون، بحث از واقع‌نمایی حقیقی و صدق گزاره‌های دینی هیچ وجهی ندارد و آنچه اهمیت دارد تنها جنبهٔ مفید بودن گزاره‌هاست. این نوع تبیین از علل پدید آمدن و بقای ادیان در طول تاریخ بشری به لحاظ معرفت‌شناختی چالش‌های فراوانی را پدید می‌آورد که به خصوص در ادیان گزاره‌محور و منتسب به وحی الهی قابل توجه است. در این نوشتار آرای ویلسون به تفصیل بیان می‌شود و مورد نقد و بررسی قرار می‌گیرد و بحث خواهد شد که شکل‌گیری معرفت دینی در یک دین‌دار باورمند تنها با نگاه کارکردگرایانۀ منفعت‌محور و با تکیه بر تبیین‌های تکاملی قابل تبیین نیست و نباید از نقش سایر مؤلفه‌های معرفتی-دینی، عقلی و احساسی غفلت کرد.

In economic theory it is circumstances that dictate fashion. During the last quarter of the century, years marked by an unprecedented escalation of material production, economists of all persuasions, neoclassicals or Marxists, accorded an important place to theories of growth. Economic reductionism being fundamental, development was likened to growth, which tends to take pars pro toto and to ignore the difference between a necessary condition and a sufficient one. Suddenly economic theory, to which mechanical formalization would confer the appearance of (...) an almost scientific rigour, became a powerful argument for the ideology of growth. (shrink)

Review of Fuller’s New Sociological Imagination.

This essay offers a motivational conception of solidarity that can be employed across the entire range of sciences and humanities, while also filling a gap in the motivational spectrum conceived by decision theorists and economists—and expanding the two-part division between altruistic and selfish motivations into a tripartite analysis that suggests a spectrum instead. According to the present proposal, solidarity is a condition of action-readiness on behalf of a group or its interests. The proposal will admit of measuring the extent to (...) which Prisoner’s Dilemmas are overcome in real life via acts of solidarity. (shrink)

The traditional practice of establishing morphological types and investigating morphological organization has found new support from evolutionary developmental biology (evo-devo), especially with respect to the notion of body plans. Despite recurring claims that typology is at odds with evolutionary thinking, evo-devo offers mechanistic explanations of the evolutionary origin, transformation, and evolvability of morphological organization. In parallel, philosophers have developed non-essentialist conceptions of natural kinds that permit kinds to exhibit variation and undergo change. This not only facilitates a construal of species (...) and higher taxa as natural kinds, but also broadens our perspective on the diversity of kinds found in biology. There are many different natural kinds relevant to the investigative and explanatory aims of evo-devo, including homologues and developmental modules. (shrink)

Patterns in the data on human sexuality support the hypothesis that the bases of sexual emotions are products of natural selection. Most generally, the universal existence of laws, rules, and gossip about sex, the pervasive interest in other people's sex lives, the widespread seeking of privacy for sexual intercourse, and the secrecy that normally permeates sexual conduct imply a history of reproductive competition. More specifically, the typical differences between men and women in sexual feelings can be explained most parsimoniously as (...) resulting from the extraordinarily different reproductive opportunities and constraints males and females normally encountered during the course of evolutionary history. Men are more likely than women to desire multiple mates; to desire a variety of sexual partners; to experience sexual jealousy of a spouse irrespective of specific circumstances; to be sexually aroused by the sight of a member of the other sex; to experience an autonomous desire for sexual intercourse; and to evaluate sexual desirability primarily on the bases of physical appearance and youth.The evolutionary causes of human sexuality have been obscured by attempts to find harmony in natural creative processes and human social life and to view sex differences as complementary. The human female's capacity for orgasm and the loss of estrus, for example, have been persistently interpreted as marriage-maintaining adaptations. Available evidence is more consistent with the view that few sex differences in sexuality are complementary, that many aspects of sexuality undermine marriage, and that sexuality is less a unifying than a divisive force in human affairs.

In this paper I suggest that play is a distinctive behavioural category whose adaptive significance calls for explanation. Play primarily affords juveniles practice toward the exercise of later skills. Its benefits exceed its costs when sufficient practice would otherwise be unlikely or unsafe, as is particularly true with physical skills and socially competitive ones. Manipulative play with objects is a byproduct of increased intelligence, specifically selected for only in a few advanced primates, notably the chimpanzee.The adaptiveness of play in pongid (...) evolution is traced through the probable changes in selective pressures that occurred in hominid evolution. It is argued that fantasy was an emergent property in hominids, made possible by symbolic intelligence and language, and serving to make play complex enough to continue to provide useful practice for increasingly complex later skills.The advent of organised instruction and education has meant that play's unplanned, intrinisic goal-setting could be replaced by extrinsic goal-setting in the systematic development of particular skills. However, the need to ensure adequate motivation has continued to give play educational value. In addition, its capacity to enhance innovative behaviour seems to be a residual function of play which has acquired a new cultural importance. (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.

Ethologists and others studying animal behavior in a spirit are in need of a descriptive language and method that are neither anachronistically bound by behaviorist scruples nor prematurely committed to particular Just such an interim descriptive method can be found in intentional system theory. The use of intentional system theory is illustrated with the case of the apparently communicative behavior of vervet monkeys. A way of using the theory to generate data - including usable, testable data - is sketched. The (...) underlying assumptions of this approach can be seen to ally it directly with theorizing in evolutionary biology, which has recently come under attack from Stephen Gould and Richard Lewontin, who castigate it as the Their arguments, which are strongly analogous to B. F, Skinner's arguments against point to certain pitfalls that attend the careless exercise of such thinking (and rival varieties of thinking as well), but do not constitute a fundamental objection to either adaptationist theorizing or its cousin, intentional system theory.
