Research: Evolutionary Perspectives on Intergenerational Sexuality
- This article, has been written in standard format mixed with an anthology.
While the evolutionary logic of intergenerational sexual behaviour and hebephilic attraction towards pubertal adolescents of the opposite sex is easily explained by fertility potential of such behaviour (see mentions of hebephilia), the explanation of intergenerational attractions toward prepubertal children (pedophilia/pedosexuality), or adolescent homosexual partners (pederastic inclination), or the very existence of prepubertal child sexuality, is less obvious.
The emergence of such sexuality has several evolutionary explanations with varying degrees of evidence, which come from ethology and neuroscience. There are suggestions that, in our evolutionary past, pedosexual behaviors could have had some evolutionary functions or been an evolutionary by-product of human sexuality development.
A by-product of lack of success in male competition
One hypothesis is that if a male is unsuccessful in sexual competition for fertile females, and he chronically feels inferior to others and is afraid of other adults, then his sexuality towards adults may be suppressed and redirected towards children, because children do not cause fear, and next to them the male feels his strength and superiority. Male's sexuality is more associated with dominance and this may explain the greater prevalence of attraction to children among men than among women. [1]

- "Examination of the characteristics of children that the paedophiles found most attractive points to the conclusion that the ability to achieve social dominance over the child may be the key to understanding the paedophile’s choice of sex target."
- "Viewed in this way, paedophilia would seem to be one of several alternative adaptations to the problem of lack of success (or perceived inability to succeed) in intermale competition for access to females. It has been often noted by ethologists that the males of any species are thrown into strong Darwinian competition with one another. Those that are most successful monopolise an unequal share of female resources, and the others have to make do with various substitute sexual outlets. Following this model, we would not expect to find any genetic predisposition toward paedophilia per se, but as with homosexuality and certain other sex deviations, some degree of heritability would be mediated by the constitutional basis of dominance versus submissiveness. In other words, paedophiles may inherit their submissive nature, which in turn makes for difficulties in establishing normal sexual roles."

The concept of "nest helper", is an explanation of a few individuals within a group being nonreproductive, yet aiding their group's survival. They may be affectionately disposed and caring towards others without reproducing, since this promotes the reproduction of peers who share some of the same genes due to being genetic relatives in the group. Due to sexual competition and the costs of human reproduction, not every individual can reproduce, hence there are indirect genetic benefits of "nest helping" that may overcome benefits of direct reproductive efforts for some individuals. This evolutionary hypothesis applies to both exclusive homosexuality and exclusive pedophilia, although due to a lack of investigation, there is at present little evidence for it (Feierman, 1990[2]).

- "Whereas a similar challenge has been met somewhat reasonably in terms of the "nest helper" concept of adult homosexuality, hypothesizing that another type of nest helper would have to erotically love and sexually interact with the children for whom he was caring"
Fertilization
For many primates, sexual behavior requires learning. Therefore, in some species, adult primates who have sexual contact with juveniles may help them develop sexual skills. In addition, sex can trigger the onset of fertility. Such a function could have played a role in the human evolutionary past (Dienske, 1990[3]). In some species, this function has built in to that extent that without early sexual experience with an adult an individual grows up unable to conceive ("In the squirrel monkey (Saimin), captivity-raised individuals of both sexes in mixed-sex peer groups were not even able to conceive unless they had been allowed, when they were juveniles, to have sexual contact with opposite-sex adults (Hopf, 1979, personal communication)."[4]).
“Peripheralize and attract strategy”
The emergence of nonexclusive pedophilic interest could be due to males experiencing selection pressure to display affiliative behavior towards minors. Such a display aims to convince fertile females that the male is ready for paternal investment, thus giving advantages in access to the fertile female (Taub, 1990[5]).

- "Why then are these unrelated males forming special affiliations with and investing in these infants? Proponents of this view suggest that males form special relationships with infants as a means whereby they may develop a closer and stronger affiliative relationship with the infant's mother. This enhanced, or special, relationship with the mother, in turn, enhances the male's chances of mating with this female in the future."
Sex as a buffer for aggression
Ethologist Irenäus Eibl-Eibesfeldt suggested that the interconnection between sex and dominance is the basic ("reptilian") way of vertebrate sexuality organization. Aggression and dominance acquired a functional connection with male sexuality due to the fact that aggressive and dominant males tended to win in sexual competition. In contrast, submission was embedded in female sexuality. The submissive posture of the female ready for mating is a stimulus to transform male’s aggressive drive to the sexual drive. This prevents injuries and allows mating to occur. Thus aggression, dominance and submission were sexualized, and sexuality acquired the ability to buffer aggression in hierarchical relationships. (The manifestation of that ability is that the appeasing posture of a defeated enemy in animals often resembles the posture of a female ready to mate). Eibl-Eibesfeldt supposed that it is possible that this function could be partly transferred into the adult-juvenile hierarchical relationship (Eibl-Eibesfeldt, 1990[6]).

- “Dominance between group members is also expressed by ritualized mounting, and submission, in turn, is expressed by female-type presenting. From these kinds of greeting rituals have evolved behaviors such as those of hamadryas baboons, in which males approaching high-ranking individuals present as if they, the presenters, were females. Their buttocks are hairless and red in mimicry of the female buttocks, thus enhancing the signal value of presenting (Wiclder, 1966, 1967b). The high-ranking individual may mount or just perform the intention to mount in response to the other's presenting. This use by primates of sexual motor patterns to acknowledge dominance rank order has often been interpreted as being equivalent to human homosexuality. This interpretation is an oversimplification. These sexual motor patterns are derived from copulatory behaviors but, then, have acquired a new function related to social hierarchies: mounting serves as an indication of dominance, and presenting serves as an indication of submission, an agonistic buffer in a greeting context”
- “Children have characteristics, such as small size, that facilitate adult males' feeling dominant to them, as occurs in pedosexual behavior.”
Sex for reconciliation and food sharing
The reduction of social tension mediated by sociosexual contact is widespread in the communities of human closest relatives, the Bonobos. The tension arises in situations of competition or inequality referring to any kind of resources such as food, access to reproduction or any interesting stimulus matter. In addition to the reconciliation effect, sexual contacts allow them to willingly share resources with one another. Ethologist Frans de Waal pointed that this mechanism works for individuals of any status, sex and age, including contacts between adults and infants. Via this mechanism, adults share food with juveniles who are not their descendants and are not of reproductive interest. The emergence of this mechanism presumably occurred as a result of an evolutionary shift in relationships between males and females towards the more tolerant and equal in the case of Bonobos (de Waal, 1990[7]). Among most other primates except for humans, cases of adults, especially males, sharing food with another's offspring are quite rare (Mackey, 1990[8]).
Frans de Waal suggests that our ancestor’s sexual behavior may have been similar to Bonobo's. This sex-for-food mechanism then allowed females to exchange sex for male commitment and paternal investment, thus giving rise to the human nuclear family. And subsequently, the very development of the nuclear family led to an increasing restriction of sex functions to heterosexual reproductive bonding only (de Waal, 2006[9]).
Excerpts:
- De Waal, Frans B. M. (1990). Sociosexual behavior used for tension regulation in all age and sex combinations among bonobos. In: Jay R. Feierman (Ed.), Pedophilia: Biosocial Dimensions (pp. 378–393). Springer, New York. doi:10.1007/978-1-4613-9682-6_15
- “Sociosexual behavior occurred with equal frequency and equal intensity in all age and sex combinations possible. Intergenerational sex was part of this general pattern. The bonobo's sexual reconciliation and reassurance patterns were described and contrasted with the behavior of the chimpanzee, which virtually lacks this nonreproductive function of sexual behavior.”
- "A young female approached a male, who was eating sugar cane. They copulated in short order, whereupon she took one of the two canes held by him and left. In another case a young female persistently presented to a male possessor, who ignored her at first, but then copulated with her and shared his sugar cane (Kuroda, 1984, p. 317)."
- "[T]he most logical pathway by which sexual behavior evolved into a general reassurance mechanism is that this mechanism was first established in the adult male/female relationship, after which it was adopted in other age and sex combinations. In other words, the widespread application of sexual behavior patterns in the bonobo' s social life has its origin in an emphasis on heterosexual bonding (de Waal, 1987). Field research supports this view in that male/female relationships seem closer and more tolerant in bonobos than in chimpanzees."
- de Waal, Frans B. M. (2006). Bonobo Sex and Society. Scientific American, 16, 14-21, doi:10.1038/scientificamerican0606-14sp
- "Given its peacemaking and appeasement functions, it is not surprising that sex among bonobos occurs in so many different partner combinations, including between juveniles and adults. The need for peaceful coexistence is obviously not restricted to adult heterosexual pairs."
- “In fact, nuclear families are probably incompatible with the diverse use of sex found in bonobos. If our ancestors started out with a sex life similar to that of bonobos, the evolution of the family would have required dramatic change.
- Human family life implies paternal investment, which is unlikely to develop unless males can be reasonably certain that they are caring for their own, not someone elses, offspring. Bonobo society lacks any such guarantee, but humans protect the integrity of their family units through all kinds of moral restrictions and taboos. Thus, although our species is characterized by an extraordinary interest in sex, there are no societies in which people engage in it at the drop of a hat (or a cardboard box, as the case may be). A sense of shame and a desire for domestic privacy are typical human concepts related to the evolution and cultural bolstering of the family."
Sex as an attachment promoter
In addition to the “reptilian” connection between sex and dominance, Eibl-Eibesfeldt described another way of sexuality organization. That evolutionary later way is the interweaving of sex and attachment, which is typical for birds and some mammals forming long-term reproductive alliances. The ability of males to form attachment and exhibit caring behavior to a sexual partner is highly beneficial for females. Human evolution went through an increase in the maturation time of offspring, which led to huge reproductive costs for females. Thus, there was a particularly strong sexual selection of males, in which sexual desire was accompanied by consistent caring behavior towards the female and her offspring. This attachment to a sexual partner may be evolutionarily linked to child-parent attachment (in some species, this connection is manifested in the features of sexual courtship rituals containing signs of childish behavior, which function to induce caring behavior and affection in a sexual partner). So according to this theory, the functional system of parental care and the functional system of mating became interconnected. Eibl-Eibesfeldt wrote that romantic love occurs through the fusion of parental care and sexual desire, and this fusion is an antecedent for children and adolescents to evoke romantic feelings in some adults (Eibl-Eibesfeldt, 1990 [6]).
In line with Eibl-Eibesfeldt, ethologist Herman Dienske argues that, in the course of evolution, due to the ability of human females to conceal ovulation and to be continuously sexually receptive, male sexual interest has evolved in turn to foster consistent male proximity (to invest in offspring that take so long to mature), and subsequently could promote male proximity with the infant (Dienske, 1990[3]). Indeed, the repertoire of pedosexual behavior observed in humans, besides sexual actions, may also include caring behavior: comforting/caressing, feeding, grooming (body care such as washing or massage), protecting, teaching (Feierman, 1990[4]).

- “If one observes courtship and greeting rituals in birds and mammals, one soon becomes aware that the patterns by which a friendly affiliation is established, upheld, or strengthened are basically derived from maternal behaviors and infantile appeals that trigger these patterns.”
- “Since human adult/adult romantic love is derived by phylogeny from parental caregiving behavior, it is easily seen how, in some adult humans, the feeling of love toward children has been retained and eroticized”

- “the associations among sex, affiliation, and paternal care are not compelling in that alternative functional solutions exist. Nevertheless, the affiliation-promoting effect of sex seems apparent.”
- “Human females, in contrast, lack such signals and thus have what is called "concealed ovulation" (Alexander and Noonan, 1979); in fact, the timing of human ovulation was not known until recently. Uncertainty concerning the time at which ovulation occurs would promote frequent copulations. It is possible that continuous sexual behavior in human females is their afflliation-promoting strategy, since it can induce more consistent male proximity (Daniels, 1983).”
- “[P]edophilic and homosexual nonprocreative sexual contacts could be considered functional, since favors resulting from the affiliation, which is maintained in part by sexual behavior, can be considerable.”

- "some of the components of parental investment, collectively called "nurturing behavior", are seen in both pedo-and ephebophilia and can be considered and discussed as (1) comforting and contact, (2) feeding, (3) grooming, (4) protecting, and (5) teaching."
Mentions of the hypothesis in mainstream literature
This hypothesis is also mentioned in modern scientific encyclopedias:
- “the evolutionary explanation behind the origin of pedophilia refers to the fusion of two evolutionarily ancient adaptive systems – reproduction and nurturing. Money (1990) states that a pedophile’s relationship to a child qualitatively, and also neurologically, resembles a blend between parental and erotic love. Likewise, it can be linked to the close cohesion between these two systems that can be observed also between phylogenetically close species.” (Klapilová & Bártová 2017, p. 7444 [10]).
- ”The founder of the human ethnology field, Irenäus Eibl-Eibesfeldt (1973), directly warns about the type of affiliative-erotic relationship that connects to the composition of long-term partnership, which was developed both in mammals and birds together with nurturing behavior, and therefore it is not surprising that they are occasionally mixed in humans.” (Klapilová & Bártová 2017, p. 7444 [10]).
- “We would entertain the hypothesis proposed separately by Eibl-Eibesfeldt (1990) and by Money (1990) that two innate biosocial propensities – caregiving and sex-mating – have become fused in the course of ontogeny in those who display the paedophilic orientation.” (Stevens & Price 2016, p. 210 [11]).
- “...affiliative erotic love, as Eibl-Eibesfeldt points out, itself evolved in birds and mammals together with the development of parental care-giving behaviour. ‘Since human adult/adult romantic love is derived by phylogeny from parent care-giving behaviour,’ asserts EiblEibesfeldt, ‘it is easily seen how, in some adult humans, the feeling of love toward children has been retained and eroticised, which is the true meaning of the term “pedophilia”.’ “ (Stevens & Price 2016, p. 213 [11]).
Neurological and endocrinological aspects
Human sexuality researchers have confirmed the neurobiological interconnection of sexual and attachment systems. The release of oxytocin, vasopressin and prolactin, hormones associated with parental behavior, during sex and orgasm stimulates the formation of attachment, altruistic behavior and care for a partner. The reverse is also true: trusting and caring relationships can evoke sexual interest (Dewitte & Marieke, 2012 [12]; Fleischman, 2021 [13]).
Two decades after Eibl-Eibesfeldt suggested that the neural systems of sex and care are relatively more connected in people who are sexually attracted to children, neuroscientists have found some experimental evidence for that. Brain structures responsible for social connections, altruistic and parental motivation (such as the left anterior insula), in people with pedophilic interest, respond to infant stimuli more intensively, receiving reinforcement from the neural circuits responsible for mating. In addition, a greater connection between parental and mating systems is characteristic of males, which is explained by evolutionarily different ways of forming maternal and paternal investments (Ponseti et al., 2018 [14]).
Excerpts
- Ponseti et al., 2018 Decoding Pedophilia: Increased Anterior Insula Response to Infant Animal Pictures. Front Hum Neurosci.
- “This gives rise to the assumption that increased brain responses to infant stimuli in pedophilia are rather a consequence of an over-active nurturing system than of an over-active sexual system.”
- “The left anterior insula, being a crucial area of nurturing processing, was also frequently found to be activated in sexual brain studies (Stoleru et al., 2012). Furthermore, the left anterior insula (as well as the SMA) is a constituent of the human attachment system, thereby enabling both nurturing and pair-bonding (Feldman, 2016). Based on both observations, (i) the over-responding to nurturing stimuli in various motivational areas and (ii) the functional overlap of nurturing and sexual processing of the involved left anterior insula a tentative and simple model of pedophilia could be as follows: Nurturing stimuli receive additional processing resources by mating-circuits. In case of human infant stimuli this leads to a sexual connotation of infant stimuli. This idea is supported by the suggestion that nurturing and pair-bonding are two closely inter-related domains in humans at the level of physiological functions, brain processing, and involved neuropeptides”
- "In any case, from an evolutionary perspective, paternal nurturing is an unusual and probably more recently evolved male behavior. Phylogenetically speaking, male brains are not “geared” to handle infant stimuli. This may explain why the “parental caregiving” network of males and females displays differences (Abraham et al., 2014).
- It might be hypothesized that, in contrast to ancient maternal infant stimulus processing, human male brains process infant stimuli with brain areas that might not be associated primarily with caregiving. If so, it is conceivable that the involvement of brain areas not “geared” to the paternal nurturing aspects associated with infant stimuli makes male brains vulnerable to not maintaining the functional division between the domains of nurturing and mating behavior."
Complementary behavior among minors
The hypothesis of pedophilic attraction as a promoter of affection and care is confirmed by the existence of complementary behavior of minors, who often show initiative and willingness for sexual relations with adults[15]. It’s assumed that such a behavior could function to receive affection and extra resources not available from the child's default caregiver. This testifies to the evolutionarily beneficial and reciprocal essence of intergenerational attraction (Klapilová & Bártová, 2017 [10]; Stevens & Price, 2016 [11]; Rind, 2013 [16]).
- “The child’s adaptive behavioral function to demand nurture from adults and his prospective urge to perform sexual activities is not mentioned too often. Still, it is a rather widespread behavior across cultures and historical periods that can help the child receive extra resources not available from their own parents. It would therefore be a complementary strategy – from the pedophile’s side, there is the eroticization of nurturing behavior and attraction to signalization that encourages caretaking, whereas from the child’s side, it is a functional, environmentally conditioned strategy that brings benefits in the form of resources and possibly even acquisition of sexual experience and calibration of child sexuality” (Klapilová & Bártová 2017, p. 7445 [10]).
- “it is undeniable that many children in our society – especially those in boarding schools and childrens’ homes – suffer from ‘parent hunger’. They are what Mia Kellmer-Pringle has called ‘touch-hungry children’. It is possible that the care-eliciting ‘phylism’ in these children may become eroticized just as the care-giving phylism may be eroticized in adult paedophiles. Thus, children starved of parental affection may compete for the love and attention of adults in their environment by using erotic solicitation as a strategy for survival. To suggest this possibility is not to excuse adults who exploit the emotional needs of children for their personal gratification but to provide an evolutionary explanation as to how and why erotic bonds between adults and juveniles may occur. We would propose that both care-eliciting and care-giving phylisms can be eroticized.” (Stevens & Price, 2016, p. 214 [11]).
Evolutionary by-product of human neotenization
Another factor of pedosexual attraction emergence is a human neotenization. The evolutionary advantage of retaining neotenic (childish) traits which elicit nurturing responses from adults, results in the retention of neotenic genetic traits due to sexual competition. Therefore such traits become sexually attractive. That leads to the observable progressive neotenization of humans in comparison with ancestors and subsequently increases likelihood of juveniles being sexually attractive. Since fertile females retained juvenile traits into their fertile years, the line between fertile and infertile female age became blurred. Thus, some males become oriented toward females who are too young for reproduction (Feierman, 1990[2]).

- “All of these genetically and culturally transmitted processes blur the distinction between reproductively competent adults and children and adolescents. Therefore, all of these processes must be considered to be determinants, at some level, of pedo- and ephebophilia.” “pedo-and ephebophiles, like chins and spandrels, may have no primary adaptive function in themselves but, instead, may be rank-ordered by-products of selection for more adaptive attributes in their kin.”
Mentorship-Bonding/Enculturation-Alliance Hypothesis
On the basis of previously available evolutionary explanations (Mackey, 1990 [8]; Muscarella, 2000 [17]; Kirkpatrick, 2000 [18]; Neil, 2009[19]), Bruce Rind developed a hypothesis explaining the most widely documented type of male homosexuality in human history, namely pederasty (the relationship between a man and a peripubertal/adolescent boy) (Rind, 2013 [16]).
It is assumed that the evolutionary function of man-boy sexual relationships comes from our evolutionary past, when the environment was very different from the modern one. Humans have had a long evolutionary history as hunter-gatherers. This time was characterized by intergroup warfare and the hunting of large animals. To do this, it was necessary to form close-knit same-sex male groups, to form specific male skills of war and hunting, and to maintain the specific masculine culture of this group. This created a selection pressure to create a mechanism to facilitate such rallying, recruitment and enculturation of new members, which is a long-term and labor-intensive undertaking. It is hypothesized that the sexual attraction between a boy and a man became such a mechanism, through the ability to form a strong emotional connection, prompting the mentor to teach and care, and the boy to seek training and a role model.
The evolutionary benefit of such a mechanism is assumed both at the individual level (for the junior this is training, protection, and promotion in the male hierarchy, for the adult this is the expansion of the network of alliances) and at the group level (the clan received a reliable replenishment of group members, well-prepared, enculturated and committed to the culture of the group, which gave a competitive advantage).
This hypothesis is supported by cross-cultural studies, where a variety of independent cultures demonstrate the prevalence of sexual relations between men and boys of peripubertal age. These relationships are built into these cultures and are part of growing up and becoming a man. The readiness, desire and initiative for sexual contact comes not only from adult men, but also from boys, and this is recorded as a typical phenomenon in these cultures. This also confirms the existence of an evolutionary benefit for younger participants.
Moreover, this attraction is not associated with reproductive losses, unlike exclusive homosexuality. It is typical of all these cultures that, upon reaching adulthood, men get wives and at the same time have sexual relations with boys themselves. It is assumed that this ability of the average heterosexual male to experience pederastic attraction is specific to our species.
But this ability is optional (facultative). That is, unlike obligate heterosexual attraction, pederastic interest is to a large extent activated or suppressed by the social environment. This explains the fact that there is a sharp difference in the prevalence of pederastic behavior and attraction between cultures, and the fact that in modern Western cultures it does not manifest itself widely.

In: Thomas K Hubbard, Beert Verstraete (Eds.), Censoring Sex Research: The Debate over Male Intergenerational Relations. (pp. 1-90) New York: Routledge. doi:10.4324/9781315432458
- “Formally, this hypothesis holds that pederasty evolved in the early human hunter-gatherer EEA [Environment of Evolutionary Adaptedness] as an adaptation (i.e., exaptation), whose function it was to reproduce the male group by facilitating the mentoring and enculturation of boys from peripubescence through adolescence, as well as their emotional and psychological binding with the group. This function was a solution to the recurring adaptive problems in the EEA of surviving and exploiting an extremely dangerous and competitive social and physical environment”
- “In short, the ages of boys sought out as recruits in male groups, the period in which they are mentored and enculturated, the ages of boys that men in such societies (and our own) find erotically appealing, the ages at which boys are especially open to being mentored (and capable as well, owing to an emergent adult-cognitive capacity), and the ages at which they are open to pederastic relations appear to be part of a single package, in which each of these characteristics seems to be a design feature and element of a larger design, whose function is reproducing the male group.”
- “It is important to emphasize that pederasty’s relatively infrequent expression in societies such as ours does not imply that it is not an adaptation. In our society, developmental inputs have traditionally been intensely hostile toward homosexual behavior, often accompanied by severe social sanctions, including public disgrace and punishment, which can be expected to have had a significant dampening effect on the emergence and activation of pederastic desire and the expression of pederastic behavior.”
- “Thus, even though adaptive in the EEA , pederasty, being a facultative trait, is nevertheless rare in our environment. On the other hand, in cultures with cultural ideologies and social structures facilitative of pederastic desire and expression, its occurrence has been widespread across the male population, which is consistent with the assumptions that most males have at least a moderate potential for the behavior and that such potential is sufficient for the behavior to emerge, provided other factors are not inhibitory.”
