4.7 Books Mx book reviews Competition between women A Mind of Her Own: The Evolutionary Psychology of Women by Anne Campbell Oxford University Press: 2002. 402 pp. £21.99, $40 Elizabeth Cashdan This provocative book argues that competi- tion among women has been an important, yet largely ignored, force in human sexual selection. Competition between males is usually thought to be more intense than female competition because greater male variance in reproductive success means that men are playing for higher stakes. But Campbell suggests that this is misleading: “The variance may not be as great as between males but that is irrelevant because females are not in competition with males, they are in competition with other females.” Mothers (not fathers) are critical to offspring sur- vival, and differences among women in their success in this endeavour have shaped the way that women think, feel and behave.

  • A Few Good Men: Evolutionary Psychology and Female Adolescent Aggression Anne Campbell Durham University, England
    ELSEVIER A Few Good Men: Evolutionary Psychology and Female Adolescent Aggression Anne Campbell Durham University, England Criminologists have drawn attention to the fact that crime peaks in the teens and early 20s and that this pattern shows invariance over culture, history, offense, and sex. Wilson and Duly (1985) have proposed that among young, disadvantaged mules, the age-crime curve reflects risky tactics aimed at averting "reproductive death." Though young women's rate of involvement in violent crime is much lower than men's, they also show a similar age-violence curve for assault. This paper proposes that this may be the result of aggressive mate selection among young women and that, under certain specified dgcumstances, women may engage in low-key intrasexual strategies in addition to epigamic strategies. This pa- per reviews material on sex differences in violent crime and in mate selection strategies, and offers predictions about the likely circumstances under which females will use intrasexual strategies. The scant available data on female adolescent fighting suggest that female-female assaults are more common than official statistical estimates and that they are frequently triggered by three key issues related to reproductive fitness: management of sexual reputation, competition over access to resource-rich young men, and protecting heterosexual relationships from takeover by rival women. KEY WORDS: Aggression; Female; Mate selection. H irschi and Gottfredson (1983) make a compelling argument for the invariance of the age-crime curve. The association between youth and heightened crime rate, they argue, holds constant regardless of histor- ical period, country, race, type of crime, and (most relevant for the present discussion) sex.

I began my graduate career in the Department of Sociology at the University of Washington, where the great sociobiologist Pierre van den Berghe taught all his career. I was a stupid SSSM (“Standard Social Science Model”) sociology graduate student then, and I joined the chorus of the confederacy of dunces to ridicule Pierre’s sociobiological work. More than a decade later, I discovered evolutionary psychology on my own by reading Wright's The Moral Animal, and converted to it overnight. When I began working in EP, I apologized to Pierre for having been too dense to see the light a decade earlier, and told him my grand plan to introduce EP into sociology and revolutionize social sciences. Pierre was encouraging but cautious. He told me that he had tried to do that himself a quarter of a century earlier but to no avail. Sociologists were just too stupid to understand the importance of biology in human behavior, a view that he has expressed in print (van den Berghe, 1990), and he eventually left the field in disgust. Blinded by youthful optimism and ambition, I did not heed Pierre’s cautionary words and tried very hard to introduce EP into sociology.

  • Marxist, Conflict, and Feminist 95
    CHAPTER 6 CriticalCritical Theories:Theories: Marxist,Marxist, Conflict,Conflict, andand FeministFeminist At the heart of the theories in this chapter is social stratification by class and power, and they are the most “politicized” of all criminological theories. Sanyika Shakur, aka Kody Scott, came to embrace this critical and politicized view of society as he grew older and converted to Afrocentric Islam. Shakur was very much a member of the class Karl Marx called the “lumpenproletariat” (a German word meaning “rag proletariat”), which is the very bottom of the class hierarchy. Many critical theorists would view Shakur’s criminality as justifiable rebellion against class and racial exploitation. Shakur wanted all the material rewards of American capitalism, but he perceived that the only way he could get them was through crime. He was a total egoist, but many Marxists would excuse this as a trait that is nourished by capitalism, the “root cause” of crime. From his earliest days, he was on the fringes of a society he clearly disdained. He frequently referred to whites as “Americans” to emphasize his distance from them, and he referred to black cops as “Negroes” to distinguish them from the “New African Man.” He called himself a “student of revolutionary science” and “rebellion,” and advocated a separate black nation in America. Conflict concepts dominated Shakur’s life as he battled the Bloods as well as other Crips “subsets” whose interests were at odds with his set. It is easy to imagine his violent acts as the outlets of a desperate man struggling against feelings of class and race inferiority.

Email: [email protected] Received April 28th, 2011; revised June 2nd, 2011; accepted July 3rd, 2011. This paper suggests how violence prevention can be better informed by embracing an evolutionary approach to understanding and preventing violent crime. Here, ethical crime control through an evolutionary lens is consid- ered and speculation is offered as to what an evolution-evidenced crime reduction programme might look like. The paper begins with an outline of the current landscape of crime prevention scholarship within criminology and presents some possible points of contact with actual or possible violence reduction practice, including child homicide and violence against women. The paper concludes with suggestions for an ethical research agenda for reducing violence, whereby it is hoped that an audience of open-minded criminologists and diverse students of evolution may lend a hand in increasing the sophistication of the criminological study of violence prevention.

  • Sex Differences in Aggression: What Does Evolutionary Theory Predict?
    BEHAVIORAL AND BRAIN SCIENCES (2009) 32, 249–311 Printed in the United States of America doi:10.1017/S0140525X09990951 Does sexual selection explain human sex differences in aggression? John Archer School of Psychology, University of Central Lancashire, Preston PR1 2HE, United Kingdom [email protected] http://www.uclan.ac.uk/scitech/research/rae2008/psychology/ staff_profiles/jarcher.php Abstract: 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.

  • Female Competition and Its Evolutionary Consequences in Mammals
    Biol. Rev. (2011), 86, pp. 341–366. 341 doi: 10.1111/j.1469-185X.2010.00149.x Female competition and its evolutionary consequences in mammals Paula Stockley∗ and Jakob Bro-Jørgensen Mammalian Behaviour & Evolution Group, School of Veterinary Science, University of Liverpool, Leahurst Campus, Neston CH64 7TE, UK (Received 20 October 2009; revised 20 June 2010; accepted 23 June 2010) ABSTRACT Following Darwin’s original insights regarding sexual selection, studies of intrasexual competition have mainly focused on male competition for mates; by contrast, female reproductive competition has received less attention. Here, we review evidence that female mammals compete for both resources and mates in order to secure reproductive benefits. We describe how females compete for resources such as food, nest sites, and protection by means of dominance relationships, territoriality and inter-group aggression, and by inhibiting the reproduction of other females. We also describe evidence that female mammals compete for mates and consider the ultimate causes of such behaviour, including competition for access to resources provided by mates, sperm limitation and prevention of future resource competition. Our review reveals female competition to be a potentially widespread and significant evolutionary selection pressure among mammals, particularly competition for resources among social species for which most evidence is currently available. We report that female competition is associated with many diverse adaptations, from overtly aggressive behaviour, weaponry, and conspicuous sexual signals to subtle and often complex social behaviour involving olfactory signalling, alliance formation, altruism and spite, and even cases where individuals appear to inhibit their own reproduction. Overall, despite some obvious parallels with male phenotypic traits favoured under sexual selection, it appears that fundamental differences in the reproductive strategies of the sexes (ultimately related to parental investment) commonly lead to contrasting competitive goals and adaptations.
