3.5 Evolutionary perspectives on crime

Evolutionary perspectives on crime examine how biological evolution has shaped human tendencies towards both prosocial and antisocial behaviors. This approach integrates insights from biology, psychology, and anthropology to provide a comprehensive framework for analyzing criminal conduct.

The theory explores genetic influences, evolutionary adaptations, and cultural factors that contribute to criminal behavior. It considers how certain antisocial traits may have conferred adaptive advantages in ancestral environments, while also examining how modern contexts can trigger maladaptive responses.

Origins of evolutionary criminology

• Evolutionary criminology applies principles of biological evolution to understand criminal behavior and its origins
• This approach examines how evolutionary processes have shaped human tendencies towards both prosocial and antisocial behaviors
• Integrates insights from biology, psychology, and anthropology to provide a comprehensive framework for analyzing crime

• Risk-taking and impulsivity as potentially adaptive traits in unpredictable environments
• Aggression and dominance as strategies for securing status and resources
• Deception and cheating as alternative methods for gaining advantages in social interactions

Reproductive strategies

• Criminal behavior as a means of increasing reproductive success
• Male-typical crimes (violence, theft) as ways to acquire resources and status to attract mates
• Sexual coercion and rape as extreme and maladaptive expressions of male reproductive strategies
• Female-typical crimes (infanticide, partner violence) often related to mate retention or offspring investment

Sexual selection and criminal behavior

• Applies principles of sexual selection to understand gender differences in criminal behavior
• Examines how mate choice and intrasexual competition influence antisocial tendencies
• Considers the role of physical and behavioral traits in criminal conduct from an evolutionary perspective

Male vs female offending patterns

• Males commit a higher proportion of violent and property crimes across cultures
• Female criminality often involves relational aggression, child neglect, or prostitution
• Evolutionary explanations focus on differential parental investment and reproductive strategies
• Testosterone levels and male-typical brain organization associated with increased risk-taking and aggression

Mate competition and violence

• Intrasexual competition leads to higher rates of male-on-male violence
• Status-seeking behaviors in males often involve risk-taking and criminal activities
• Mate guarding and sexual jealousy as drivers of intimate partner violence
• Female competition more often involves indirect aggression and reputational attacks

Parental investment theory

• Explains differences in male and female behavior based on their relative investment in offspring
• Applied to understand patterns of child maltreatment and family-related crimes
• Considers how resource scarcity and environmental stress affect parental care and neglect

Child abuse and neglect

• Evolutionary perspective views child maltreatment as a maladaptive expression of parental investment strategies
• Stepparent effect: higher rates of abuse in families with non-biological caregivers
• Maternal neglect often related to lack of resources or support for child-rearing
• Paternal abuse more commonly linked to uncertainty of paternity or resource competition

Infanticide and filicide

• Infanticide examined as a reproductive strategy in certain environmental contexts
• Postpartum depression and psychosis as potential evolved mechanisms gone awry
• Sex-biased infanticide in cultures with strong son preference
• Filicide (killing of older children) often related to extreme forms of family conflict or mental illness

Kin selection and nepotism

• Explains altruistic behavior towards genetic relatives based on shared genes
• Applied to understand family-based criminal activities and patterns of cooperation in illegal ventures
• Examines how genetic relatedness influences decisions to engage in or report criminal behavior

Family-based criminal networks

• Kinship ties facilitate trust and cooperation in organized crime groups
• Mafia families as extreme examples of kin-based criminal organizations
• Genetic relatedness influences recruitment and loyalty within criminal networks
• Familial DNA databases raise ethical questions about kin liability in criminal investigations

Altruism vs selfishness in crime

• Kin selection explains seemingly altruistic criminal acts that benefit relatives
• Nepotism in white-collar crime and corruption often involves favoring family members
• Conflict between individual self-interest and family loyalty in criminal decision-making
• Whistleblowing less likely when it would implicate close genetic relatives

Life history theory and crime

• Applies evolutionary principles to understand how individuals allocate energy and resources across their lifespan
• Examines how early life experiences shape behavioral strategies, including criminal tendencies
• Considers the trade-offs between current and future reproduction in relation to risk-taking behaviors

Fast vs slow life strategies

• Fast life history strategy associated with earlier sexual maturity, more offspring, and higher risk-taking
• Slow life history strategy involves delayed reproduction, fewer offspring, and lower risk-taking
• Adverse childhood experiences often lead to fast life history strategies and increased criminal propensity
• Socioeconomic status and environmental predictability influence life history trajectories

Age-crime curve explanations

• Universal pattern of criminal behavior peaking in late adolescence/early adulthood
