Comparative analysis of the behavior of modern primates, in conjunction with an accurate phylogenetic tree of relatedness, has the power to chart the early history of human cognitive evolution. Adaptive cognitive changes along this path occurred, it is believed, in response to various forms of complexity; to some extent, theories that relate particular challenges to cognitive adaptations can also be tested against comparative data on primate ecology and behavior. This paper explains the procedures by which data are employed, and uses (...) the best currently available evidence to derive a proposal for some of the stages through which human cognition evolved, before the last common ancestor with a nonhuman, and the reasons that cognitive adaptations were favored in primate evolution.

Philosophers have recently argued that since there are people who are blind, but don't know it, and people who echolocate, but don't know it, conscious introspection is highly unreliable. I contend that a second look at Anton's syndrome, human echolocation, and ‘facial vision’ suggests otherwise. These examples do not support skepticism about the reliability of introspection.

Changes in government policy over the last two decades have seen the traditional goals of criminal justice, namely prosecution and punishment, being replaced by an emphasis on prevention, fear reduction, security and harm reduction. During this time domestic abuse has gained a place on the political agenda, which has resulted in legislative initiatives in the form of civil protection orders across the U.K. which primarily focus on prevention but have also more recently begun to rely on the traditional criminal justice (...) responses should they fail to prevent further abuse. Drawing on international evaluations and a recent study conducted in Scotland (the Scottish study), the article examines whether legislation in the form of civil protection orders has the effect of curtailing the actions of abusers and if not, what occurs when the traditional criminal justice response comes into play. The strengths of civil protection orders and some explanations for the weaknesses of these orders are considered alongside the question of whether there is any value in women continuing to engage with the law in response to domestic abuse.

The classical social theorist Emile Durkheim proposed the counterintuitive thesis that crime is beneficial for society because it provokes punishment, which enhances social solidarity. His logic, however, is blemished by a reified view of society that leads to group-selectionist thinking and a teleological account of the causes of crime. Reconceptualization of the relationship between crime and punishment in terms of evolutionary game theory, however, suggests that crime (cheating) may confer benefits on cooperating individuals by promoting stability in their patterns of (...) cooperation.

My response is organized into three sections. The first revisits the theme of the target article, the explanatory power of sexual selection versus social role theory. The second considers the range and scope of sexual selection, and its application to human sex differences. Two topics are examined in more detail: (1) the paternity uncertainty theory of partner violence; (2) evolution of inter-group aggression. Section 4 covers ultimate and proximal explanations and their integration within an ethological approach. I consider the development (...) of sex differences in aggression, and their causal mechanisms, within this framework. (shrink)

Human females are generally reserved in their sexuality, in keeping with their heavy investment in reproduction. Males tend to be less reserved. Relative to males, however, females demonstrate more variability in sexuality and are more likely to inhibit or express high levels of sexuality. The heightened variability may in part originate with genetic mechanisms that predispose females toward greater variability. Menarche, menstrual cycles, menopause, food reactions, responses to living conditions, reactions to cultural factors, and responses to sexual stimuli and potential (...) mates are unique to or are more variable among females than males. There is a correlation between the variation expressed and female reproductive potential—females tend to shift dramatically from sexual inhibition to sexual expression. Females apparently track the quality of the environment and link their sexuality to reproductive opportunities. Successful male reproduction depends less on quality environments and more on the availability of females. In short, females track the environment; males track the females. (shrink)

I argue that the magnitude and nature of sex differences in aggression, their development, causation, and variability, can be better explained by sexual selection than by the alternative biosocial version of social role theory. Thus, sex differences in physical aggression increase with the degree of risk, occur early in life, peak in young adulthood, and are likely to be mediated by greater male impulsiveness, and greater female fear of physical danger. Male variability in physical aggression is consistent with an alternative (...) life history perspective, and context-dependent variability with responses to reproductive competition, although some variability follows the internal and external influences of social roles. Other sex differences, in variance in reproductive output, threat displays, size and strength, maturation rates, and mortality and conception rates, all indicate that male aggression is part of a sexually selected adaptive complex. Physical aggression between partners can be explained using different evolutionary principles, arising from the conflicts of interest between males and females entering a reproductive alliance, combined with variability following differences in societal gender roles. In this case, social roles are particularly important since they enable both the relatively equality in physical aggression between partners from Western nations, and the considerable cross-national variability, to be explained.

Females make large investments in their children and compete among themselves to establish and maintain privileged relationships with male allies who demonstrate both an ability and a willingness to provide fitness-enhancing advantages. Various “strategies” and their more numerous, associated “tactics” are utilized in the competition. Alleged strategies include using sexuality, producing offspring, assisting the male in his own intrasexual contests, and harassing female competitors. The strategies in question are documented in multiple primate species, including humans living in various times and (...) places. Some variables are discussed that influence the degree to which human females rely upon them. (shrink)

Empirical research has demonstrated that women’s aggressive behavior is widespread and displays regularities across societies. Until recently, however, discussions about the aggressive behavior of women and gender differences in aggressive behavior have been based largely on data from nonhuman primates, children, or laboratory experiments. Using a unique corpus of naturalistic data on aggressive human interactions both between and among men and women, I explore the complexity of our questions about sex differences in aggression and further illuminate the ways in which (...) men and women may use aggression in human interactions. In this paper I compare the aggressive behavior of men and women in an Australian Aboriginal community. In doing so I argue for the continuing use of a “sex differences” framework for organizing our understanding of gender relations and gender hierarchy. I believe, however, that this form of analysis benefits from, if not requires, a sensitivity to the most taken-for-granted aspects of our gender ideology and a commitment to attend to evidence that challenges our convictions about men and women.

The paper offers contextual and integrating comments about sex, evolution and psychopathology as a point of departure toward a new and more scientific understanding of human neurosis. The evolved roots of neurotic behavior are firmly linked to theorems of evolution, which is emerging as the basic science of psychopathology. Evolutionary tenets serve to: 1) redefine key aspects of neuroses, 2) place neurotic behavior in a broad and integrated evolutionary context, and 3) pose basic questions for all psychopathology. Readers who wish (...) to expand, clarify or confirm elements of might well consult basic books in either field as a passing familiarity with psychiatry and biology is assumed. (shrink)

A noteworthy development that has transpired in American sociology in the past quarter century has been the increasingly sophisticated interest in the analysis of human cultural systems. Sadly, however, these analyses reveal that social scientists rarely appreciate the profoundly evolutionary aspects of human culture. The chief purpose of this essay is to address this shortcoming and to offer some tentative suggestions toward its rectification. The essay begins by briefly reviewing recent developments in the analysis of cultural systems, primarily by reference (...) to the influential work of Wuthnow. Second, a common flaw in these approaches is addressed—namely, the absence of any recognition of the value of grounding sociocultural theory in an informed evolutionary framework—and the case is made that this shortcoming is avoidable, even within the context of the intellectual traditions of the social sciences. Third, the evolutionary foundations of human cultural behavior are explored in terms of an analysis of relevant theoretical and empirical developments in the evolutionary neurosciences. Fourth, the value of these insights is illustrated by reference to an evolutionary critique of a recent and thought-provoking contribution to the study of modern political culture—Douglas and Wildavsky’s analysis ofRisk and Culture. Finally, the article concludes by emphasizing the value of and the necessity for incorporating evolutionary reasoning into the domain of sociocultural theory. (shrink)
