In this blog post, we will examine the adaptationist perspective—which interprets rape as an evolutionary adaptation—along with the critiques of this view from anti-adaptationist and feminist perspectives, and explore how this debate is understood in contemporary academia.
Rape is recognized as one of the most serious crimes in society. Whenever a rape case occurs, public condemnation intensifies, and public opinion calling for harsher punishments grows stronger. At the same time, various interpretations are put forward regarding the causes of rape. Some focus on the perpetrator’s personal tendencies or antisocial traits, while others argue that social factors, such as violent media or pornography, play a role.
However, evolutionary psychology has also presented a different perspective. Some adaptationist researchers have attempted to understand rape—while acknowledging it as a clear crime in societal terms—as a byproduct of biological adaptation that emerged during the evolutionary process or as a specific adaptive strategy. This view remains a subject of significant debate in academia today and is currently being critiqued and reexamined across various academic disciplines.
This debate is also introduced in Jang Dae-ik’s ‘Darwin’s Table’. The book explains the arguments of adaptationists while also presenting various counterarguments. Therefore, this article aims to examine both the perspective that interprets rape as an adaptation and the representative criticisms of it, and to review the significance of this debate.
From an adaptationist perspective, it is suggested that there may have been differences in the average behavioral tendencies of men and women within human reproductive strategies. In evolutionary biology, it has generally been discussed that men may have evolved strategies to increase their reproductive opportunities, while women may have evolved strategies to carefully select mates due to the high costs associated with pregnancy and child-rearing. Based on these average tendencies, some researchers have raised the possibility that sexually coercive behavior may also be an adaptive strategy that emerged during the evolutionary process.
This perspective often cites historical examples—such as sexual violence during wartime or social institutions like polygamy—to explain that a variety of sexual behaviors have existed in human society. However, even modern evolutionary psychology makes it clear that these historical examples do not justify the crime of rape or imply that it is an inevitable behavior. Biological explanations are merely attempts to explore the origins of specific behaviors; they do not imply ethical justification.
Furthermore, modern society protects sexual self-determination based on law, ethics, and human rights, and all forms of sexual violence are defined as clear crimes. Therefore, even if the possibility that a certain behavior has an evolutionary background is discussed, this does not mean that it is socially acceptable.
Of course, many criticisms have been raised against such adaptationist interpretations. Notably, anti-adaptationist researchers, including evolutionary biologist Stephen Jay Gould, point out that explaining rape as an adaptation is an overly simplistic interpretation. ‘Darwin’s Table’ introduces these criticisms through a review of ‘A Natural History of Rape’.
He used statistical data to conclude that women of childbearing age suffer greater harm from rape than women who are not of childbearing age. However, a reanalysis of the same data could also reveal that there is no significant difference in terms of psychological trauma or physical harm between female victims aged 44 and older and those aged 12 to 44. Furthermore, it has been criticized that comparing the severity of harm in cases of sexual violence against children aged 12 and under based solely on the victims’ statements is not an appropriate method. Moreover, the fact that cases involving child victims who are incapable of pregnancy account for a significant proportion is cited as evidence that rape cannot be explained by reproductive strategy alone. Jang Dae-ik, ‘Darwin’s Table’, Kimyoungsa, 2008, p. 22.
Such criticisms emphasize that theories explaining rape as a reproductive strategy fail to adequately account for the diverse manifestations of the crime in reality. Sexual violence against women outside their fertile period—which has no direct connection to reproduction—as well as child sexual abuse, incest, and sexual violence arising from power dynamics, are difficult to explain through reproductive strategy alone. Today, both criminology and psychology tend to view sexual violence as a crime resulting from the interplay of complex factors such as power, domination, aggression, individual disposition, and sociocultural environments.
Meanwhile, researchers who support the adaptationist perspective argue that the existence of such counterexamples does not completely invalidate evolutionary explanations. They emphasize that evolutionary psychology is not a discipline that seeks to explain every single case with a single cause, but rather a theory aimed at explaining average behavioral tendencies. In other words, it is not a claim that all rapes stem from reproductive strategies, but rather a hypothesis that explores the evolutionary background of certain behaviors.
Furthermore, evolutionary biology recognizes that a single behavior can be influenced by multiple factors. Human behavior arises from the combined effects of not only biological factors but also culture, social norms, an individual’s upbringing, educational level, and psychological characteristics. Therefore, it is inappropriate to explain a specific behavior based on a single cause alone, and there are ongoing calls for adaptationism to fully account for this complexity.
In addition, some studies discuss how human sexual objects or preferences may be influenced by sociocultural environments. Research indicates that in modern society, various media and cultural content can influence the formation of an individual’s sexual perceptions to a certain extent. However, these influences cannot be definitively identified as direct causes of sexual violence, and the view that biological and sociocultural factors interact is now more widely accepted in academia.
Criticism of adaptationism comes not only from anti-adaptationism but also from feminist scholarship. Attempts to explain rape biologically often include the premise that men and women have fundamentally different behavioral patterns regarding reproduction. In response to this premise, feminist researchers argue that human sexual behavior and gender roles cannot be explained by biology alone, and that the sociocultural environment plays a crucial role. The following is an excerpt from ‘Feminism and Science’.
Starting from a biological perspective, sex researchers argue that human sexuality is fundamentally constructed and is not strictly limited by genetics or hormones. Human infants are bisexual or, to borrow Freud’s term, “polymorphous.” However, there is a very long process from these biological sex differences to the complex construct of gendered sexual identity, behavior, roles, and desires that adults possess, and culture exerts a major influence on that process. For example, even in studies on the gender identity of intersex individuals, it is not only biological sex but also the expectations of parents and society that are crucial in predicting gender identity in adulthood. This suggests that social expectations play a significant role in the formation of sex and gender identity. Furthermore, our very understanding of biology can be influenced by the social environment. Sandra Harding, ‘Feminism and Science’, Ewha Womans University Press, 2002, p. 165.
To summarize this perspective, human gender roles and gender identity are not determined by biological factors alone; rather, they result from the combined influence of sociocultural environments, education, and the expectations of family and community. Consequently, critics argue that explaining male and female behavior solely through evolutionary reproductive strategies fails to adequately reflect the complexity of human behavior. For this reason, feminist scholarship understands rape as a phenomenon that must be analyzed in conjunction with social power relations, structures of gender discrimination, and cultural contexts.
On the other hand, some evolutionary psychologists argue that such criticism may also unduly downplay the role of biological factors in human behavior.
Humans are undoubtedly cultural beings, but they are also biological beings. Human behavior is the result of the complex interplay of various factors—including genetic traits, hormones, the nervous system, the environment in which one grows up, education, and sociocultural factors—and cannot be explained by any single factor alone.
In fact, even in recent evolutionary psychology research, the position that human behavior is determined solely by genes is gradually losing ground. Instead, an interactive model in which biological traits and sociocultural environments influence one another is gaining wider acceptance. From this perspective, biology and culture are understood not as opposing concepts but as factors that influence one another.
Ultimately, the debate surrounding rape is not an issue that can be resolved simply through the dichotomy of “biology versus society.” In modern criminology, psychology, sociology, and evolutionary biology, it is generally understood that sexual violence is not explained by a single cause but rather as a phenomenon resulting from the complex interplay of individual characteristics, sociocultural environments, power relations, psychological factors, and biological factors. Therefore, while adaptationism can be examined as one theoretical perspective among many, it is not accepted as a single theory that explains sexual violence in its entirety.
As we have seen, the perspective that interprets rape as an evolutionary adaptation, along with the critiques of this view from anti-adaptationist and feminist perspectives, has long been a subject of debate in academia. Adaptationism has offered a research perspective aimed at exploring the evolutionary origins of human behavior, while anti-adaptationists and feminists have criticized such explanations for failing to adequately reflect the complexity of human behavior and sociocultural factors. This debate continues today across various academic disciplines that seek to understand human behavior.
Above all, it is clear that sexual violence is a serious crime that cannot be justified from any perspective. Researching the causes of human behavior is not intended to condone crime, but rather to develop more effective prevention and response strategies. In fact, modern criminology does not view sexual violence solely as individual deviant behavior but is making efforts to understand it by synthesizing research findings from various fields, including psychology, sociology, psychiatry, neuroscience, and evolutionary biology.
Furthermore, recent studies emphasize that a complex interplay of factors—such as individual aggression, lack of empathy, power orientation, distorted perceptions of sexuality, childhood experiences, and sociocultural environments—can influence the occurrence of sexual violence. Therefore, it is difficult to explain every case using just a single theory. While biological explanations can be considered one possibility among various explanations, they are not accepted as a theory that fully explains the complex social phenomenon of sexual violence.
Ultimately, the core of the debate surrounding rape lies not in asserting that any single position is absolutely correct, but in the academic attempt to understand human behavior from diverse perspectives. Adaptationism is significant in exploring the evolutionary background of human behavior, while anti-adaptationism and feminism emphasize the sociocultural factors, power relations, and human diversity that such explanations may overlook. Through this mutual criticism and examination, our understanding of human behavior can become more refined.
The prevention of sexual violence must also be carried out within this multidisciplinary framework. Prevention efforts can be more effective when they are accompanied not only by stricter legal penalties but also by proper sex education, gender equality education, strengthened victim protection systems, psychological counseling, recidivism prevention programs, and social efforts to foster healthy interpersonal relationships. Studying the causes of human behavior from multiple angles is significant not as a means to justify a specific theory, but as a process for developing more effective prevention policies and social responses.
