Most attempts to define culture as used in the cultural evolution literature treat culture as a single phenomenon that can be given a single nondisjunctive definition. In this article I argue that, really, cultural evolutionists employ a variety of distinct but closely related concepts of culture. I show how the main prominent attempts to define a culture concept fail to properly capture all the uses of “culture” employed in cultural evolutionary work. I offer a description of some of the most (...) important culture concepts used by cultural evolutionists. (shrink)

Kim Sterelny and Paul Griffiths (Sterelny 1992, Sterelny and Griffiths 1999) have argued that sociobiology is unworkable because it requires that human behaviors can be adaptations; however, behaviors produced by a functionalist psychology do not meet Lewontin's quasi-independence criterion and therefore cannot be adaptations. Consequently, an evolutionary psychology which regards psychological mechanisms as adaptations should replace sociobiology. I address two interpretations of their argument. I argue that the strong interpretation fails because functionalist psychology need not prevent behaviors from evolving independently, (...) and it relies on too strong an interpretation of the quasi-independence criterion. The weaker interpretation does not undermine sociobiology, and evolutionary psychology would be vulnerable to the same criticism. Finally, I offer reasons to think that both mental mechanisms and behaviors can be adaptations. (shrink)

This paper discusses problems associated with the use of optimality models in human behavioral ecology. Optimality models are used in both human and non-human animal behavioral ecology to test hypotheses about the conditions generating and maintaining behavioral strategies in populations via natural selection. The way optimality models are currently used in behavioral ecology faces significant problems, which are exacerbated by employing the so-called ‘phenotypic gambit’: that is, the bet that the psychological and inheritance mechanisms responsible for behavioral strategies will be (...) straightforward. I argue that each of several different possible ways we might interpret how optimality models are being used for humans face similar and additional problems. I suggest some ways in which human behavioral ecologists might adjust how they employ optimality models; in particular, I urge the abandonment of the phenotypic gambit in the human case. (shrink)

In order to explain why cultural traits remain stable despite the error-proneness of social learning, Dan Sperber has proposed that human psychology and ecology lead to cultural traits being transformed in the direction of attractors. This means that simple-minded Darwinian models of cultural evolution are not appropriate. Some scientists and philosophers have been concerned that Sperber’s notion of attractors might show more than this, that attractors destroy subtle cultural variation and prevent adaptive cultural evolutionary processes from occurring. I show that (...) Sperber’s view does not have this consequence—that even if there are attractors, cumulative cultural evolution can still occur. (shrink)

The collective Tiqqun’s 2001 tract, Raw Materials for a Theory of the YoungGirl, in which they stress the way modern girl culture represents the triumph of capitalism, has recently drawn fresh attention. Here I consider the argument about girls made in this text and its perhaps surprising relevance to contemporary feminist accounts of girlhood and girl culture.

This paper tries to explain how individuals manage adaptive individual choice (i.e., the decision to acquire a fitter than average behavior or idea rapidly and tractably) in cultural evolution, despite the fact that acquiring fitness information is very difficult. I argue that the means of solving this problem suggested in the cultural evolution literature largely are various types of decision rules employing representations of fitness correlated properties or states of affairs. I argue that the problem of adaptive individual choice is (...) best solved where some of these learning rule representations are socially transmitted and some are biologically transmitted. (shrink)

Geoffrey Miller argues that we can account for the evolution of human art and altruism via the action of sexual selection. He identifies five characteristics supposedly unique to sexual adaptations: fitness indicating cost; involvement in courtship; heritability; variability; and sexual differentiation. Miller claims that art and altruism possess these characteristics. I argue that not only does he not demonstrate that art and altruism possess these characteristics, one can also explain the origins of altruism via a form of group selection and (...) traits with the five characteristics in terms of a process I call "cultural sexual selection.".

Why is it that we watch _Mad Men_ and think it represents a period? Flashes of patterned wallpaper, whiskey neat, babies born that are never mentioned, contact lining for kitchen drawers, Ayn Rand, polaroids, skinny ties, Hilton hotels, Walter Cronkite, and a time when Don Draper can ask ‘What do women want?’ and dry old Roger Sterling can reply ‘Who Cares?’ This essay explores the embrace of period detail in _Mad Men_ finding it to be both loving and fetishistic, and (...) belonging, like all period film, to the politics of the present.

David Buller and Valerie Hardcastle have argued that various discoveries about the genetics and nature of brain development show that most ?central? psychological mechanisms cannot be adaptations because the nature of the contribution from the environment on which they are based shows they are not heritable. Some philosophers and scientists have argued that a strong role for the environment is compatible with high heritability as long as the environment is highly stable down lineages. In this paper I support this view (...) by arguing that the discoveries Buller and Hardcastle refer to either do not show as strong a role for the environment as they suggest, or these discoveries show that the brain's developmental process depends in many cases on input from the environment that is highly stable across generations.

This paper addresses the question of how to understand the relationship between Cultural Evolutionary Science and the social sciences, given that they coexist and both study cultural change. I argue that CES is best understood as having a unificatory or integrative role between evolutionary biology and the social sciences, and that it is best characterized as a bridge field; I describe the concept of a bridge field and how it relates to other non-reductionist accounts of unification or integration used in (...) the philosophy of science literature.

This dissertation is designed to discuss central issues raised by two of the evolutionary behavioral sciences, sociobiology and evolutionary psychology. Both sciences purport to be able to explain the origins of human behavioral and cognitive adaptations respectively and give us some insight into "human nature." My purpose is to go some way towards determining how well these two sciences do as means of determining human evolutionary origins, both by examining some of the central issues that they face, and by examining (...) several case studies in which their methods have been applied to specific human behaviors. ;Sociobiology in particular has had a bad reputation, at least in part because s few of its proponents have used the project as a forum for pushing conservative social values. It has attracted a lot of criticism: in particular for being unwarrantedly adaptationist, and for addressing its explanations at behavior, rather than at psychology. Evolutionary psychology, on the other hand, has been better received; there is some belief that it is a more appropriate, less "behaviorist" project than sociobiology. I spend the first part of the dissertation examining some of these criticisms; however, I believe the charge adaptationism to be founded on the practices of individuals rather than being a central commitment of the project; I also conclude that the claim that behaviors cannot be adaptations to be unfounded. Furthermore, far from being a better project than sociobiology, I conclude that evolutionary psychology relies on a flawed central commitment to universal domain-specificity to establish its psychological conclusions, and its models rely on an unanalyzed notion of good design. ;In the second part of the dissertation I evaluate three well known and controversial studies that use sociobiological or evolutionary psychological methods to try to account for some bard to understand elements of human behavior: namely infanticide, art and altruism, and rape. Although the quality of this work is rather mixed, I conclude there is reason to think that natural selection is implicated to some degree in the origins of some of these behaviors. (shrink)

This paper critiques the competing “Grandmother Hypothesis” and “Embodied Capital Theory” as evolutionary explanations of the peculiarities of human life history traits. Instead, I argue that the correct explanation for human life history probably involves elements of both hypotheses: long male developmental periods and lives probably evolved due to group selection for male hunting via increased female fertility, and female long lives due to the differential contribution women’s complex foraging skills made to their children and grandchildren’s nutritional status within groups (...) provisioned by male hunting.

In “Out of Eden” David Barash argues that humans are naturally polygamous, in that they have innate polygamous preferences. In particular, Barash argues that human males have preferences and other psychological states designed to support aggressive polygynous sexual competition, and that the resulting behavior has driven the selection of various other psychological and behavioral traits in humans. This is controversial, since the prevailing view of the human mating system in our recent evolutionary history was that it was choice-based and only (...) mildly polygynous. In this review I evaluate Barash’s arguments and conclude that he has not made his case for the stronger view. (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)

I belong to a generation of cultural studies researchers for whom Stuart Hall was not the primary voice defining the field as I first encountered it. He was not even among the first wave of writers that I read or heard discussed as doing ‘cultural studies’. Instead, I came to Hall’s work from a distance defined by the history of cultural studies as a discipline; first by the diffusion of some of its most important interventions through other fields, so that (...) it was not only people who said they were doing cultural studies who were taken up as key to the field, and second by the institutionalisation of a cultural studies canon in which Hall became only one voice, however influential. Nevertheless, by the time Hall died I had come not only to an enthusiastic appreciation of his work but to strongly feel my own indebtedness to it. I want to reflect here on how teaching cultural studies brought me to a close engagement with Hall’s work, and how teaching keeps Hall’s work and ideas alive when the exigencies of academic publishing might relegate him to citational history.

Sarah Hrdy argues that women (1) possess a reproductive behavioral strategy including infanticide, (2) that this strategy is an adaptation and (3) arose as a response to stresses mothers faced with the agrarian revolution. I argue that while psychopathological and cultural evolutionary accounts for Hrdy's data fail, her suggested psychological architecture for the strategy suggests that the behavior she describes is really only the consequence of the operation of practical reasoning mechanism(s) – and consequently there is no reproductive strategy including (...) infanticide as such, nor could the alleged strategy be sufficiently mosaic to count as an adaptation. What might count as an adaptation is a ‘window’ before bonding that permits practical reasoning about the reproductive value of infants and hence variable maternal investment, and which, contra (3) arose early in hominid history due to a combination of increases in infant dependency and increased human abilities for conditional practical reasoning.
