bonobos, chimps, theory of mind, and sex
bonobo mother and child
Jacinta: So how is the bonobo influence faring these days – in Afghanistan, Iran, Trumpistan, Pakistan, China, Russia, Israel and Burma, to name a few…?
Canto: Okay, enough goat-getting. I’m still fascinated by how bonobos – more genetically similar to chimps, of course, than to humans – came to be so different. It’s not genetics, so what is it? It can’t just be diet, or habitat. And, my feeling is, if you know how something works, you can build it yourself. Like, if you know how beehives work you can build your own beehive, which we’ve done.
Jacinta: Not quite the same as building a new social system methinks. Though they have tried, haven’t they? ‘Let’s go to the Americas and build a Paraiso en el Nuevo Mundo‘… ‘But isn’t it already inhabited?’ ‘Yeah, we might need a bit of rubbish-clearing to start with’.
Canto: You’d think that our discovery of the bonobo lifestyle, really only a few decades ago, its feminism, its relative pacifism, its great community spirit, not to mention the sex, would be of interest to more than just a few primatologists, especially given the world of warfare, rapine and religious numbskullduggery that so many of us are still trapped within – it makes me scream with frustration.
Jacinta: It seems that the timber of humanity is more crooked than that of bonobos. I reckon we took a really wrong turn a few million years ago, so now we’re lost in the patriarchal jungle and we’ll never find our way back.
Canto: But bonobos are showing us the way don’t you see? And if humans didn’t make life so difficult for them, and their habitat wasn’t so fouled and fenced in by human depredations, they’d be so numerous, such a dominant force in the landscape, they’d put us to shame.
Jacinta: Haha we’re a pretty shameless species I’m afraid. Anyway, aren’t bonobos the anomalous ones? Chimps vastly outnumber them, despite the same human depredations. It be Nature, and what do please Evolution. If they hadn’t been separated into two species by the formation of the Congo River, they’d still be one species, and patriarchal, I’m betting.
Canto: Wow, who’s side are you on? Whether bonobos’ ancestors were patriarchal or not is beside the point to me. The point is, they’re matriarchal now, who cares when it started. And they’re happy, and successful. And we humans want to be happy, or happier, and more successful. So we might learn from bonobos about being less aggressive, less cruel, less exploitative, less competitive, and more caring, more playful, more communal, more uninhibited…
Jacinta: Okay, okay, I get it. But I’m wondering about that aggression, or at least that competitiveness. Hasn’t it been to our advantage as a species? The space race, the battles between competing scientific theories, between political ideologies and the like, haven’t they sharpened the collective human mind? Aren’t bonobos a bit intellectually lazy? I’ve read somewhere that chimps are more consistent toolmakers than bonobos. Or would you rather we lived in some timeless hippy-bonobo nirvana?
Canto: Okay, let’s look at the evidence, or what we have of it. Michael Tomasello et al published a research study in the journal PloS One in 2010, entitled ‘Differences in the Cognitive Skills of Bonobos and Chimpanzees’. Here’s the whole abstract from it:
While bonobos and chimpanzees are both genetically and behaviorally very similar, they also differ in significant ways. Bonobos are more cautious and socially tolerant while chimpanzees are more dependent on extractive foraging, which requires tools. The similarities suggest the two species should be cognitively similar while the behavioral differences predict where the two species should differ cognitively. We compared both species on a wide range of cognitive problems testing their understanding of the physical and social world. Bonobos were more skilled at solving tasks related to theory of mind or an understanding of social causality, while chimpanzees were more skilled at tasks requiring the use of tools and an understanding of physical causality. These species differences support the role of ecological and socio-ecological pressures in shaping cognitive skills over relatively short periods of evolutionary time.
Mirroring individual differences observed in theory of mind development in human children, the more cautious and socially tolerant bonobos outperformed chimpanzees on the theory of mind scale. Meanwhile, the prolific tool-using chimpanzee, whose survival is more dependent on extractive foraging, outperformed bonobos in the tool-use and causality scale.
This pattern can potentially be interpreted as suggesting that bonobos are more skilled at solving problems requiring an understanding of social causality, while chimpanzees are more skilled at solving problems relating to physical causality. In contrast, the two species did not differ in the scales measuring their understanding of problems related to spatial comprehension, discriminating quantities, using and comprehending communicative signals and learning from others via a social demonstration. This pattern of findings provides support for the hypothesis that socio-ecological pressures play an important role in shaping the cognitive differences observed between these species.Long-term observations of wild chimpanzees have suggested that female chimpanzees acquire more proficient tool-using techniques faster than males, and other studies show a similar pattern in captive bonobos. Therefore, it may be that socio-ecological pressures play a more limited role in producing cognitive differences based on sex in these species, but it also suggests that female Panins pay closer attention to others which allows them to learn and solve social problems more quickly and skillfully than males (while both sexes perform similarly in physical cognition tasks).
bonobos, an outlier in the primate world, and yet…
any excuse for a nice bonobo pic
In trying to develop a bonobo world with human characteristics, or perhaps more realistically a human world with bonobo characteristics, I suspect it’s best not to start by disparaging the male (human) brain as ‘unevolved’ or distinctly inferior to that of the female – something I heard in an interview with a male psychotherapist recently. Firstly, it make no sense to say that a brain, or a human, or a dog, a dolphin or a donkey is ‘unevolved’. This is a fundamental misunderstanding of evolution, which is about ongoing change to most effectively adapt to a changing environment. And this includes social environments. The Andamanese, a tiny population living on scattered islands in the Bay of Bengal from about 25,000 years ago, and driven almost to extinction in the 18th and 19th centuries by the introduction of measles, influenza, pneumonia, and alcohol, have recovered somewhat and preserve their simple lifestyle via extreme hostility to interlopers, and are no more unevolved than were the ancient Hominins who once lived on the Indonesian island of Flores. It’s true, of course, that evolution can be competitive, and some species – or sub-species or cultures – can win out over others, but to describe this as due to being ‘more evolved’ rather over-simplifies matters. Each species evolves to survive and thrive in its own niche, and may thrive in that way for an eon, but may be swept away by another invasive species, or by relatively sudden climate change, or by very sudden events such as meteor showers or volcanic eruptions.
In the same interview, the psychotherapist described the male brain, including his own, as sick and in some sense mentally unbalanced compared to the female brain. And you can go onto YouTube and other sources to find dozens of mini-lectures and expert opinions on the male versus the female brain.
However, it might surprise people to know that there is no categorical difference between the male and female brain, at least not in the sense there is, usually, between a male and female body. Put another way, if a neurologist with decades of experience was given a disembodied brain and asked about its sex, she wouldn’t be able to say, categorically, whether it was male or female. There are statistical differences – males have, on average, more ‘grey matter’ (individual neurons) while females have more ‘white matter’ (myelinated axons connecting neurons) – but there is great diversity within this frame, which should hardly surprise us. Our brains develop within the womb, subject to the diet and environmental conditions of our mothers, and genetic and epigenetic factors have their role to play. In early childhood neural connections multiply rapidly in response to a multitude of more or less unique conditioning factors, and new connections continue to be made well into adulthood, resulting in more than eight billion tediously unique noggins clashing and combining in tediously unique ways.
So, to me, it’s behaviour that we need to start with. Of course I’m interested in the nervous system and the endocrine system of bonobos, but that’s because I’m first and foremost taken by their behaviour. I’m encouraged by what I see as changes in male behaviour in the WEIRD world, but then I was told recently that male violence against women is actually increasing. Of course these things are hard to measure as not all violence is reported, and the very concept of violence may be disputed, but a quick look at figures for Australia, which surely qualifies as a WEIRD nation, suggests that my sense of things is right:
Experiences of partner violence in the 12 months before the survey (last 12 months) remained relatively stable for both men and women between 2005 and 2016. However, between 2016 and 2021–22 the proportion of women who experienced partner violence decreased from 1.7% in 2016 to 0.9% in 2021–22.
Australian Institute of Health and Welfare (Australian Government)
Whatever one might think of these figures, there’s little evidence of an increase in male violence (against females), at least here, in this teeny WEIRD nation. So maybe it’s places like Australia, and New Zealand, far from some of the major global threats, slowly building a multi-ethnic culture (largely proof against the massive social divisions stifling the divided ‘USA’), an oasis of 26 million compared to the bonobo oasis of maybe 20 thousand, a region that still likes to think of itself as ‘young and free’, and prepared to experiment with our politics and culture, maybe it’s here that bonobo-style caring-and-sharing behaviour can start to make some headway (but of course even as I write this it strikes me as ridiculous).
The trouble, of course, is that it’s hard to focus on such a possible future without sex rearing its not-so-ugly head. In human culture we’re obsessed with beauty (both male and female) in a positive way (though bad luck if you happen not to be physically attractive), and obsessed with sex in a much more confused but largely negative way (‘licentiousness’, a very human term, is generally condemned in all societies). Do bonobos distinguish between each other in terms of ‘good looks’? If not, when did we, or our ancestors start to do so? There has of course been much talk of ‘sexual selection’ in anthropology, going back to Darwin, but in bonobo society, where female-female sex predominates but sex, generally in the form of mutual masturbation, occurs among and between all age groups and genders, sexual selection (for breeding purposes) would only occasionally operate. And after all, masturbation is about one’s own erogenous zones, which, like being tickled, are best aroused by another, no matter what they look like. Think of a dog masturbating on your leg.
One might argue that religion has a lot to answer for, in so firmly linking sex to shame and transgression, while another might argue, along with Freud, that sexual sublimation was a necessary prerequisite for human civilisation. I’m still trying to work out my own view on this, but I’d surmise that the link between sex and shame existed in humans long before the Abrahamic religions took it to extremes. And unfortunately, much of the online material on our history of sex and shame contains a lot of bollocks, so I’ve reached a dead end there.
So here’s some guesswork. It may have started with the wearing of minimal clothing to protect the reproductive parts, both from damage and from gawkers – out of sight, out of mind. Perhaps this was initiated by females, but more likely (in the case of female genitalia) by males. On this topic I’ve often read claims that pre-agricultural or non-agricultural societies were less patriarchal, and I’ve even adopted that view myself, but I suspect the difference was only in degree, not in kind.
As to patriarchy itself, consider this. Bonobos and chimps split from each other 2 million years ago, at most. From that time on, bonobos survived and thrived in a relatively circumscribed, densely forested region south of the Congo. Chimps on the other hand are more numerous and wide-ranging (with more varied habitats), and are currently divided into four sub-species, from the west to the east of sub-Saharan Africa, and their number in the wild, though hard to determine with any precision, is generally estimated as about ten times that of bonobos. And all chimps are patriarchal.
The dating of the CHLCA (the last chimpanzee-human common ancestor, and note that bonobos are excluded from this reference) has been a subject of ongoing debate and analysis. Here’s how Wikipedia puts it:
The chimpanzee–human last common ancestor (CHLCA) is the last common ancestor shared by the extant Homo (human) and Pan (chimpanzee and bonobo) genera of Hominini. Estimates of the divergence date vary widely from thirteen to five million years ago.
Obviously, this was before the chimp-bonobo divergence, and considering speculation by anthropologists that bonobo ‘female power’ might be linked to a more frugivorous diet and less of a hunting-killing lifestyle (due to their restriction to an area rich in fruits, nuts, seeds and small game), it seems likely that the CHLCA was already more patriarchally inclined. Consider also that the genus Homo sapiens, long believed to date to no more than 200,000 years ago, and arising in eastern sub-Saharan Africa, has recently been dated to over 300,000 years from remains found in faraway Morocco. That suggests the traversing of vast regions, and a diet much richer in meat than that of bonobos. So, while the hunter-gatherer term has been passionately disputed by some, it’s generally accepted – and it makes sense to me – that there was some division of labour, as implied by the term, and that it would likely be largely gender-based. So, our history, and our ancestry, has been almost entirely patriarchal.
However, this doesn’t define our future. Patriarchy is breaking down in the WEIRD world, albeit slowly. And there are, depressingly, many forces in opposition to female empowerment, especially in the non-WEIRD world. I’ll focus on that in my next post.
back to bonobos – and sex
Canto: We’re reading Rebecca Wragg Sykes’ brilliant book, Kindred, an almost up-to-date account (published in 2020) of all the new discoveries about our close relatives the Neanderthals, and the speculations resulting from them. And of course we’re always alert to the slightest mention of bonobos in any works of anthropology…
Jacinta: Yes, we’ve been a bit timid about talking too much about bonobos and sex, but a few mentions in Kindred have emboldened us.
Canto: W’ve seen the odd photo or video of chimps or bonobos with erect penises, and it was a scary but also puzzling sight, but we’ve not really explored the difference between theirs and ours, so now is the time to do so. So here’s some interesting comments linking humans, Neanderthals and our chimp/bonobo rellies:
Anatomically, pelvic dimensions point to vaginas very similar to ours, and as penises are tailored to fit, those too were probably more like living men’s equipment than that of chimpanzees.
Luckily for all concerned, unlike chimps Neanderthal males lacked the genes for ‘penis spines’. While in apes they’re more like tiny hardened pebbles than spikes, their presence does affect copulation: marmosets have sex and orgasms that last twice as long when the spines are removed.
We should probably therefore picture Neanderthal sex as more leisurely and satisfying than chimp-style rapid thrusting bouts. Not forgetting clitorises – organs solely existing for pleasure – unluckily for Neanderthals, like us they probably lacked bonobo-like versions that make face-to-face orgasms easier. But masturbation in some form is pretty much guaranteed, whether during sexual encounters as is found among humans, or more generally for social bonding and diffusing tensions, as in bonobos where it takes place between pretty much anyone.
Kindred, Rebecca Wragg Sykes, p 271
Jacinta: So this makes me want to know more about the bonobo penis, and ‘penis spines’. It sounds like it isn’t ‘made for pleasure’, which helps to explain why female-female sex is the most practised type among bonobos.
Canto: Then again chimps have the same penises as bonobos but they’ve evolved differently. So here we go with ‘penile spines’. First, Wikipedia:
Many mammalian species have developed keratinized penile spines along the glans and/or shaft, which may be involved in sexual selection. These spines have been described as being simple, single-pointed structures (macaques) or complex with two or three points per spine (strepsirrhines). Penile spine morphology may be related to mating system.
This is news to me, but fascinating.
Jacinta: Just up our alley, so to speak. So to elaborate on this last quote, again using Wikipedia (largely), strepsirrhines are a suborder of primates including lemurs, galagos or bushbabies, pottos and lorises. Sexual selection is, I presume, a form of mating system, which Darwin reflected upon in The Descent of Man, inter alia. Macaques are a type of Old World monkey, with 23 known species. Interestingly, they’re matriarchal and frugivorous, like bonobos.
Canto: Apparently they’re a feature of felines – penile spines, that is. In cats, it’s speculated that they may contribute to pregnancy, as they ‘rake the walls of the female’s vagina [during withdrawal], which may serve as a trigger for ovulation’. I’m wondering, though, how that might relate to sexual selection. ‘A spiny dick, nothing turns me on more.’
Jacinta:
It all works below the conscious level, mate. I mean, female bowerbirds hang out with the males with the best display, but I don’t think they’re thinking about sex, especially considering how much of a nothing bird sex generally is. But getting back to bonobos, Wragg refers in the above quote to ‘bonobo-like’ clitorises that make face-to-face orgasms easier than it was for Neanderthals and, more to the point, we H sapiens. How could we have missed this in all our explorations of the bonobo world?
Canto: Hmmm. I blame the prudery of researchers. Including ourselves. Anyway, it probably all gets back to genes and their expression. So we need to explore – but should we look at penises first or clitorises – is that the plural?
Jacinta: Not sure, I can only cope with one at a time. So here’s something we should never have missed:
Bonobo clitorises are larger and more externalized than in most mammals; while the weight of a young adolescent female bonobo “is maybe half” that of a human teenager, she has a clitoris that is “three times bigger than the human equivalent, and visible enough to waggle unmistakably as she walks”. In scientific literature, the female–female behavior of bonobos pressing genitals together is often referred to as genito-genital (GG) rubbing. This sexual activity happens within the immediate female bonobo community and sometimes outside of it. Ethologist Jonathan Balcombe stated that female bonobos rub their clitorises together rapidly for ten to twenty seconds, and this behavior, “which may be repeated in rapid succession, is usually accompanied by grinding, shrieking, and clitoral engorgement”; he added that it is estimated that they engage in this practice “about once every two hours” on average. As bonobos occasionally copulate face-to-face, evolutionary biologist Marlene Zuk has suggested that the position of the clitoris in bonobos and some other primates has evolved to maximize stimulation during sexual intercourse. The position of the clitoris may alternatively permit GG-rubbings, which has been hypothesized to function as a means for female bonobos to evaluate their intrasocial relationships.
Canto: What can I say?
Jacinta: So this quote, from Wikipedia, compares the bonobo clit to the human one, but says nothing about chimps. I mean, it occurs to me that this enlarged clit, and the pleasure derived from it, would help to explain female-female sexual bonding, leading to social bonding, leading perhaps to matriarchy, if we can call it that. But if chimps have the same-size female pleasure-place, that thesis collapses.
Canto: Good point. So, googling ‘chimp clitoris’ takes me first to an essay from nearly 40 years ago on ‘The external genitalia of female pygmy chimpanzees’, an early term for bonobos. The abstract actually compares Pan paniscus (bonobos) and Pan troglodytes (chimps) as if just to resolve your dilemma:
The external genitalia of four adult female pygmy chimpanzees (Pan paniscus) were examined during a 2-year period. It was found that the labia majora are retained in adults of this species and that, when tumescent, the labia minora effectively relocate the frenulum and clitoris so that they point anteriorly between the thighs. When detumescent, the configuration of the labia minora and clitoris resembles that of immature common chimpanzees (P. troglodytes). It is suggested that the simple, structural relocation of the clitoris from the normal [sic] condition noted in adult P. troglodytes makes possible the homosexual, intergenital rubbing observed in P. paniscus, when ventroventral juxtaposition of the individuals permits eye-to-eye contact. In addition, this change probably increases sexual stimulation of the female during heterosexual, ventroventral copulations.
Jacinta: Wow. So bonobos separated from chimps between 1 and 2 million years ago. And in that time a kind of structural change took place in the positioning of the clitoris. Is that plausible? And what about the swelling?
Canto: Hard to get clear info, but the general genital swellings of chimps versus bonobos differ in one respect – in chimps, they’re indicative of fertility, or ovulation, but bonobos, like humans have ‘concealed’ ovulation. A wonder that this can occur in the relatively short time since the split. Or maybe not, I’m no primatologist.
Jacinta: Apparently bonobos and humans aren’t the only primates with concealed ovulation – it also occurs in Vervet monkeys, but the very concept of ‘concealed ovulation’ is a bit controversial – as if it’s being done deliberately, which would surely be absurd. But it certainly does mean that, in those primates that don’t exhibit clear signs of ovulation, copulation occurs through all stages of the menstrual cycle. It could be a way of preventing males from being aware of their own offspring, thus reducing the infanticidal tendencies found in male, and sometimes female, chimps. As for the position of the clitoris, its shift to a more ‘accessible’ spot for genito-genital rubbing in bonobos is often mentioned as a great development for female bonding, but I can find nothing much on how this anatomical change could’ve happened.
Canto: Well, think of Darwin’s finches in the Galapagos. Certain beak shapes were more adaptive to the particular vegetation on particular islands, and birds with those beak shapes outbred other birds and became dominant, and ultimately the outright winners. With bonobos, okay this different clitoral positioning might not have led directly to those females outbreeding other females, since it might not have made it easier for males to have sex with females (though where there’s a willie there’s a way), but it might have led indirectly to females becoming dominant through sexually stimulated female bonding, allowing the females with the most changed and, to females, most alluring clitorises to choose the most male partners and so produce the most offspring.
Jacinta: Female rather than male choice. Or even females ‘sexually assaulting’ males? Definitely sounds interesting. But as always, more research is required…

Beauvoir, Stendhal, bonobos and the past
Canto: So, having read The Second Sex recently, I’m pondering over her essay on Stendhal, a writer I was a little obsessed with in the 1980s, in the years of my fading youth…
Jacinta: Right, so near the middle of that book Beauvoir wrote five little essays on five writers, treating of their treatment of women, from the most misogynist to – Stendhal. So the first four, in order, were Henry de Montherlant, D H Lawrence, Paul Claudel and Andre Breton.
Canto: Yes and she mentions Stendhal with affection in Memoirs of a dutiful daughter too, so it transports me back to my discovery of Stendhal’s work in the early eighties, and then, in the late eighties, my decision to write my French Honours thesis on Stendhal’s work, which led me to read and reread more or less all of his oeuvre, as well as much literary criticism, including, if I’m not much mistaken, Beauvoir’s essay.
Jacinta: And in that essay, she points out that Stendhal is more invested in the female characters than the males. His writing career is bookended by Lamiel, his unfinished last novel, and Armance, his first written work of fiction, which uses physical impotence effectively to disguise the emotional difficulties faced by the male lover, Octave…
Canto: Well I’ve been reading critiques, by women, of Beauvoir’s treatment of Stendhal’s treatment of women, and it all becomes a bit abstruse, but surely nobody wold doubt that Stendhal has a view of women that is very much out of synch with his time. But what most interests me, is the personal nature of his interest. Because I identify with it. I very much recall his account, in Vie de Henri Brulard, of his writing the names in sand, or was it dirt, of the women he loved (whatever that may mean), and who never returned his feelings. And watching the waves, or was it the wind, wash those names away. Stendhal was always a ‘brevity is the soul of wit’ writer, whose writing became most taut when emotionally charged. Few writers have had greater emotional impact on me than Stendhal, no doubt because I too have been a terrible failure in love, or lust, or whatever it is that brings bodily closeness, of the kind that bonobos manage so effortlessly.
Jacinta: Culture, and religion, and its aftermath, have left us with a legacy that makes physicality, so basic to other mammals, an arena replete with problems. The very process of writing illustrates this. Bonobos don’t write, or talk, they don’t put off spontaneity. If they’re spurned, as Stendhal was spurned by those he obsessed over, they find someone else, without giving up on their first choice. And if they’ve proved themselves, they might succeed in their first choice next time, without giving up on their second choice…
Canto: But maybe there’re bonobo versions of Stendhal, and myself, who don’t succeed in their first second or third choices…
Jacinta: Bonobo society is clearly inclusive. It’s not just about sex, but about closeness. That’s what makes for less violence and more collaboration. In the primate world, our world, greater female empowerment makes all the difference.
Canto: No bonobo left behind. But we have become ‘literate’, spectacularly, which has led to our science and complexity, Shakespeare and Newton and music and quantum mechanics and longevity and so many understandings of the universe and neutrinos and the butterfly effect and complex feedback loops…
Jacinta: And still there is warfare – involving the rape and murder of women – a feature of every example of warfare over the last 5000 years and more – and invariably perpetrated by men. Men men men men men men men.
Canto: What about Thatcher and the Falklands?
Jacinta: Complex, but initiated by the aggression of Argentinian males, and of course there are aggressive women…
Canto: Well getting back to Stendhal and Beauvoir, let me offer this quote from Beauvoir’s essay for our commentary:
Music, painting, architecture, everything he cherished, he cherished it with an unlucky lovers’ soul; while he is walking around Rome, a woman emerges at every turn… by the regrets, desires, sadnesses and joys women awaken in him, he came to know the nature of his own heart; it is women he wants as judges: he frequents their salons, he wants to shine; he owes them his greatest joys, his greatest pain, they were his main occupation; he prefers their love to any friendship, their friendship to that of men; women inspire his books, women figures populate them; he writes in great part for them. ‘I might be lucky enough to be read in 1900 by the souls I love, the Mme Rolands, the Melanie Guilberts…’ They were the very substance of his life.
Simone de Beauvoir, The Second Sex (Vintage Books, p261)
Jacinta: Sad. Mais touchant, tout de même. It seems like it’s both a joy and a torture. Joy in remembrance and contemplation, but suffering in the presence of their indifference, or disdain, or discomfort. And that’s how you feel? But then you have me. But of course you am I. Am you. Am I?
Canto: Haha, well it’s more like how I used to feel, before I became a dried out old husk. I could tell some comically sad tales of my youth, but now I think of these things in a more abstract way. And admiring the example of bonobos as the human way of the future is about as abstract as it gets, so I feel very comfortable about it. And I talk to myself a lot, but I’m not even sure any more if my imagined interlocutor is female.
Jacinta: Ah, the way we were. So, all passion spent, you can focus on more important things like war and peace, global warming, artificial intelligence, female empowerment, wealth inequality, the WEIRDening of the world…
Canto: And, of course, bonobos. I really would like to be one. Just for one day.

sex and gender in bonobos, humans, etc
So there’s been a lot of talk lately about trans people, whatever that may mean, and whether or not they should be taken seriously. It seems to relate to the ‘woke’ issue, for some people, and it has become a hot button issue for the most divided and tedious nation in the WEIRD world. All of this has to do with sex and gender, it seems to me, and I’ve had many thoughts on this topic ever since I was a kid, over fifty years ago.
I’ve written about this before, briefly, but I want to go into it in more detail now. I was around eleven or so, pre-pubescent, in primary school, year 5 or 6. It was school assembly, and we were standing in line outside the school buildings, listening to some headmasterly homilies. I was at the back of the two lines for our class, one for girls, one for boys. It was probably towards the end of the year, because I was very familiar with my classmates, at least by observation. As I looked at them this day, I considered which ones were the most, and least, attractive, and why. I knew nothing about sex at the time (unlike most eleven-year-olds today), but I knew about physical attraction – and attraction generally. My thoughts ran along lines which I still feel proud of to this day, though no doubt I’ll exaggerate their sophistication, as is the way with memories.
I decided that the prettiest kid in the class was a boy, and I was ‘turned on’ by the naughtiness of this thought. I also noted that of the two prettiest girls, one was much more attractive to me than the other, not because of her physical appearance, but her manner – perhaps her air of gravity, her intelligent expression, the clothes she wore, her way of walking. And then there were girls I was attracted to, but not physically. They were fun, good sports, approachable. And on further reflection I noticed that the kids who least interested me were the ‘girlie’ girls and the ‘tough guy’ boys, and that the kids in front of me could all be put on a spectrum from most masculine to most feminine, regardless of their actual genitalia. Which led me to wonder – where was I on this spectrum?
It so happens that throughout my school years I was the shortest kid in my class, male or female, and skinny with it. A less masculine male could hardly be imagined. I never considered myself homosexual though. By the time I fully understood the term, the blokes my age were developing face fuzz, which was a total turn off. That didn’t stop me from falling in love with Bowie at sixteen – the music, that is, and the in-your-face androgynous persona. This tended to make me persona non grata in the socially conservative working-class environment of my childhood and early youth.
All of this is to say that I was highly sensitised to issues of sex and gender from an early age. Some years later, well into my twenties, a certain family kerfuffle came to my attention. A married cousin had a daughter, aged about six or so, who insisted on keeping her hair short and refused to be dressed in a dress. I encountered her once or twice, and she seemed morose, withdrawn, smart, and yes, kind of masculine, if that makes sense for someone so young. My mother seemed worried, as did other family members, but the mother not so much. There was talk of doctors, of taking a firmer line, and I didn’t know what to make of it. Nobody asked my advice of course, but I would’ve argued for letting the girl, or boy, be what they wanted to be. I was thoroughly fascinated, however. But I soon lost touch with family, became as solitary as an orang-utan, and know nothing of the outcome.
Returning to modern times, people talk today of the LGBTQIA+ community, and I can probably work out what each letter signifies, but only just. It seems to me that if there is a problem here, it’s a problem of categorising and compartmentalising – maybe of working out which ‘tribe’ you supposedly belong to. I myself have never been particularly tribal, so it all just flies over my head. And anyway, is there a community here, a community of difference? I hope so, but I’m doubtful.
I’ve mentioned orang-utans, but it’s the far from solitary bonobos I’m really interested in. Opposites attract, they say. Recently I’ve been pondering sex and gender in our primate cousins, and other mammals. Does our pet dog know she’s a girl? Does our pet cat know he’s a boy? We call our pets such things to eternally infantilise them, but that’s another story. Let’s consider bonobos – when, if ever, do they learn that they’re male or female? And when do we humans learn the same? For humans, it seems straightforward – we have language. One of the first things a child learns is that they’re ‘a pretty/naughty/clever girl, or boy, as the case may be. This sort of makes up for the fact that we rarely get to go about naked and notice the difference in each others’ genitalia – unlike bonobos. But our bonobo and chimp cousins are smart and complex – they know the difference between the one who nurses and protects them and the adults who are sometimes friendly but at other times indifferent or hostile. They might not conceive it in terms of gender, but they might discern a pattern. And of course hormonal and developmental differences both between and within the two sexes will play their part. So they too have ‘gender issues’, if we can call it that.
It’s often said that sex is biological, gender is cultural. That, of course, is way too neat, and too hard to prove, because every single family in which a child is brought up is a micro-culture of sorts, and every child has a slightly different genetic and epigenetic inheritance. The problem again is our tendency to compartmentalise. What is more important, as bonobos might teach us, is acceptance of variety and difference.
Another obvious difference between bonobos and the only clothed apes, is of course, clothing, covering, hiding our ‘naughty bits’. It’s a topic I tend to be squeamish about, being human, but it needs to be addressed. We wear clothing for a whole variety of reasons – for keeping protected and warm, to display solidarity with our tribe, to be fashionable and attractive, to show contempt for fashionable elites, to avoid being arrested for indecent exposure, and so on. We certainly learn from very early on that it’s ‘rude’ and ‘uncivilised’ to go about in the altogether. It’s interesting to note that the term ‘savage’, used regularly by Europeans well into the 19th century, precisely coincided with the degree of covering used by the indigenous populations they encountered. The more covered they became, the more civilised and intelligent they became in our minds.
It’s also worth noting that, until recently in the WEIRD world, clothing and other visible accoutrements have been used to distinguish the two sexes – hence the concept of cross-dressing, which now seems dated. In my own youth my hair was long and bushy, and it seemed to me that most of the girls’ hair was shorter than the boys’, which I found titillating. At the time I thought it was revolutionary, and went along with free love and the dissolution of marriage, but sadly it turned out to be just another turn of the fashion wheel.
And yet, not quite. Or not at all. Some of us might be slaves to fashion, but the percentage has considerably reduced. Gone forever are the days, revealed in 100 year-old photos and newsreels, when men were obliged to wear more or less lookalike homburgs, and women cloche hats. Jeans, t-shirts and casual jackets are as commonplace now as they were fifty years ago, and casual apparel has maintained its non-binary style in that time. Fashions may go in cycles but they never return to the same place. Marriage is still popular, but it’s not what it was when my dad were a lad.
So at a time when sexual identity and politics are being fought over to a degree that I find laughable, it’s a relief to turn to the bonobo world. Bonobos females tend to engage in same sex acts a lot more than males do, according to research by the Max Planck Society, and this activity creates more lifelong bonds than occurs with mixed-sex pairs. The research suggests that this has to do with increased oxytocin levels after these interactions. Oxytocin, the so-called ‘feel good’ or ‘love’ hormone is often associated with the bonding of mother and child. These increased levels didn’t occur after male-female sex. Interestingly, and very surprisingly (and rather disappointingly to me) male-male sex is rare among bonobos. Considering that some 75% of bonobo sex has no reproductive purpose (compared to 99.999% of human sex, according to my own extensive research), this seems to me a missed opportunity. Then again, this female-female bonding appears to be the key, not only to female dominance, but more importantly that species’ lack of aggression compared to chimps and humans. Obviously the answer for us humans is to ban male homosexuality on penalty of death, and encourage the female version with prizes and worldwide fame for the loudest and longest orgasms.
Okay, I was a bit drunk when I wrote that.
There’s a lot more to be said, though, about how bonobos have broken the aggression habit, or how they’ve targeted aggression to reduce aggression, and so to become less aggressive overall. I’ll explore that in my next post.

why do fools fall in love, and bonobos not so much?
Animals don’t ‘fall in love’, right? Only humans do that sort of thing. But wait on – humans are animals. Darwin told me so. Funny how we keep forgetting that. Or, if we’re members of particular religions, we insist it just isn’t so. Simone de Beauvoir, in a section near the end of her monumental work The Second Sex, titled ‘The woman in love’, describes this rather mythologised experience from the second sex’s perspective:
The supreme aim of human love, like mystical love, is identification with the loved one. The measure of values and the truth of the world are in his own consciousness; that is why serving him is still not enough. The woman tries to see with his eyes; she reads the books he reads, prefers the paintings and music he prefers, she is only interested in the landscapes she sees with him, in the ideas that come from him; she adopts his friends, his enemies and his opinions; when she questions herself, she endeavours to hear the answers he gives; she wants the air he has already breathed in her lungs; the fruit and flowers she has not received from his hands have neither fragrance nor taste; even her hodological space is upset: the centre of the world is no longer where she is but where the beloved is; all roads leave from and lead to his house. She uses his words, she repeats his gestures, adopts his manias and tics. ‘I am Heathcliff,’ says Catherine in Wuthering Heights; this is the cry of all women in love; she is another incarnation of the beloved, his reflection, his double: she is he. She lets her own world founder in contingence: she lives in his universe.
I can hear plenty of women I know roaring with laughter at this description. It might seem dated and extreme, but Beauvoir directly quotes women of her time and earlier who give expression to this type of mindset, and a whole sub-genre of romantic literature is still devoted to it. And after all, humans are essentially monogamous, unlike any of the other great apes.
But how essential is our monogamy, really?
Bonobos have been lightly referred to as the ‘make love not war’ apes, or our ‘hippy’ cousins. These are telling references, methinks. I have to say that when I was a young teen, and sometimes shell-shocked witness to a very unhappy parental marriage, I had high hopes that the hippy ‘love the one you’re with’ lifestyle (and revolution) was here to stay, and that marriage, the consecration of monogamy, was on its way out. I won’t say those hopes were entirely dashed, because over the past fifty years or so, with the introduction of no-fault divorce, the greater acceptance of same sex relations and non-marital partnerships, and the drop in religious belief, traditional marriage has certainly been tottering on its pedestal. But there are other barriers to our adopting a bonobo lifestyle of all-in, apparently indiscriminate frottage and sexual healing – including our ideas about ‘true love’.
One factor, surely, has ensured the continued supremacy of monogamy in our society – the production and maintenance of offspring. While it’s generally conservatives who maintain that ideally children need a father and a mother for a ‘balanced’ upbringing (in spite of many examples to the contrary), the idea, I’ve found, niggles at many a single parent I’ve encountered. My own mother – by far the dominant parent, the breadwinner, the rule-maker, the sometimes unnerving dictator – seemed obsessed that the weakness of my father was affecting my own masculinity. She sent information my way as I grew older, about a career in the military, or the police, and made the odd – indeed quite odd – remark about homosexuality as a disturbing and unhealthy condition. I wasn’t particularly inclined that way, though as a ten-year-old I definitely found some of the boys in my class as pretty (or ugly) as the girls. And later, my discovery of David Bowie, the most intense experience of my teenage life, had a clear sexual element.
The point here is that we’re plagued with traditional notions of masculinity, femininity and monogamy which will take time to break down. But changes are afoot, and the gradual fading of religion and the great work of pioneers like Beauvoir and many intellectual heroines before and after her are making for a much more female-friendly, not to say female dominant, political and social environment. Slowly slowly catchy monkey. Or in the case of bonobos, catchuppy monkey.
Bonobos don’t live in houses. They don’t have sex in bedrooms. And, like us, at least post-religion, they don’t have sex to produce offspring. It seems that, like dogs on their masters’ legs, they’ve learned about erogenous zones, but, being smarter than dogs, have taken that a step further in terms of bonding. Humans hide away to have sex, but consume ‘adult’ videos involving sex on beaches and other open air spaces, in bars, on stages, in public toilets, in palatial residences, in the best and worst of places. It’s as if we long to be open and brazen about our sexuality, but dare not.
I note that one of the biggest sex video industry in the world is in Japan, which is also, surely not coincidentally, the least religious country in the world. It’s also not exactly a haven of feminism, to be honest, and critics, including feminists, have often targeted the sex video world as, like prostitution, a haven of macho exploitation. I prefer to see it as, at least potentially, a haven of sex without love, but not without fellow-feeling. And certainly anyone familiar with the Japanese sex video industry would have to scoff at the characterisation I’ve heard, from conservative politicians among others, that a large proportion of the females employed in the industry, are entrapped and drug-addled (as is not infrequently the case, of course, with prostitution). Having said that, it’s still clearly an industry directed primarily at male consumers.
Feminists are generally divided about the industry, between those who want to kill it off and those who want, or hope, to transform it. In any case, one of the problems is that the industry compartmentalises sex. It becomes a product, most often accessed by men, alone, in their bedrooms, sometimes by couples or groups as an aid or an inspiration. It helps with fantasy and technique but has little if anything to do with fellow-feeling or – well, love.
And yet – what I note with Japanese sex videos is that they are more story-based than those of the Euro-American industry. Yes, the stories are often repetitive and predictable, and there’s too much ‘fake rape’, with the female invariably ending up ‘enjoying’ the experience, though it appears to be a fact that rape fantasies are common among women – an issue I feel way too squeamish to explore, at least for now. The point I’m trying to make is that many Japanese videos make the effort to place sex in a domestic or workplace context, to normalise it, even if in a somewhat ludicrous, and sometimes comical, way. I also note that sometimes they involve interviews with the performers before and after scenes, giving the impression of ‘happy families’, though there are definitely cases of coercion and the situation may be worsening. Again, more female empowerment is the key to changing this environment. The fact remains that both pornography and prostitution are signs of a culture that has never really come to terms with its sexual needs and its sexual nature. If we cannot accept that sex is healthy we will continue to pursue it in ways that are unhealthy – the drive will always be with us.
So what about love, again? And its relation to sex. As Beauvoir points out, the idea that two people will be able to satisfy each other sexually, exclusively, for decades, is ridiculous. Of course, many couples become increasingly comfortable with each other and co-dependent over the years – as do two dogs more or less forced to share the same home. This may be not so much a sign of love as of the standard living arrangements developed over the centuries in our civilised world – rows of few-bedroomed homes fit for maybe three to five people set out in grids of streets serviced with all the conveniences of modern life. We don’t build for anything like a bonobo world, understandably, and it’s hard to see beyond the reality that has shaped our whole lives. Still, I’m hearing a new term that might be worth clinging to – ‘ethical non-monogamy’. Something that might be worth considering once the hormones die down and the scales fall…
So that very bonoboesque idea I’ll endeavour to explore next time.
Did bonobos do it with chimps? Well, duh
bonobos or chimps? Or both? Or neither? What’s in a name…?
Canto: So we’ve been learning than we did it with Neanderthals, and that Neanderthals did it with Denisovans, and I remember hearing an anthropologist or palaeontologist saying that it’s likely that our split with our last common ancestor with chimps and bonobos – they call it the CHLCA (chimp-human last common ancestor, eliminating bonobos altogether, sigh) – wasn’t necessarily a clean break, which surely makes sense.
Jacinta: Well, yes, as we’ve read, the split was caused by the relatively sudden creation of the Congo River, but the word ‘relatively’, is, well, relative. So this raises the question of speciation in general. Think of those Galapagos finches that so intrigued Darwin. All about differently-shaped beaks, but it didn’t happen overnight.
Canto: Right, so here’s what a website with the rather all-encompassing title “Science” says about our topic:
Tens of thousands of years ago, modern humans slept around with Neandertals and swapped some genes. Now, it turns out one of our closest living relatives, chimpanzees, also dallied with another species. New research reveals that chimps mixed it up with bonobos at least twice during the 2 million years since these great apes started evolving their own identities. Although it’s not yet clear whether the acquired genes were ultimately beneficial or harmful, the finding strengthens the idea that such cross-species mating played an important role in the evolution of the great apes.
Jacinta: Interestingly this Congo River separation which led to a completely different species was repeated by other separations which led to four sub-species of chimps. Which leads me to wonder – what’s the difference between a new species and a sub-species? Why are bonobos ‘deserving’ of being called a different species?
Canto: Well the Science article has some fascinating further information. This was the work of Christina Hvilsom and colleagues, described as ‘conservation geneticists’. They were using any genetic differences they could find to work out where particular chimps were being caught or hunted. But, since the interbreeding of humans and Neanderthals, proven by DNA, had hit the headlines, Hvilsom wondered about the DNA of chimps. So, using the same methods that uncovered Neanderthal in humans –
she and her colleagues determined that 1% of the central chimpanzee’s genome is bonobo DNA. The genetic analysis indicates that this inbreeding happened during two time periods: 1.5 million years ago bonobo ancestors mixed with the ancestor of the eastern and central chimps. Then, just 200,000 years ago, central chimps got another boost of bonobo genes, the team reports today in Science. In contrast, the western chimp subspecies has no bonobo DNA, the researchers note, suggesting that only those chimps living close to the Congo River entertained bonobo consorts.
Jacinta: What this highlights, more than anything to me, is the importance and excitement of genetic and genomic analyses. Not that we’re experts on the topic, but it has clearly revolutionised the science of evolution, complicating it in quite exciting ways. Think again of those Galapogos finches. Separation, some interbreeding, more separation, less interbreeding, but with a few kinks along the way.
Canto: And we’re just beginning our play with genetics and genomics. There’s surely a lot more to come. Ah, to live forever…
Jacinta: So how did they know some inbreeding occurred? Can we understand the science of this without torturing ourselves?
Canto: David Reich’s book Who we are and how we got here tells the story of interbreeding between human populations, and how population genetics has revolutionised our understanding of the subject. With dread, I’ll try to explain the science behind it. First, the Science article quoted above mentions a split between bonobos and chimps 2 million years ago. Others I’ve noted go back only about a million years – for example a Cambridge University video referenced below. The inference, to me, is that there was a gradual separation over a fair amount of time, as aforementioned. I mean, how long does it take to create a major river? Now, I can’t get hold of the data on chimp-bonobo interbreeding in particular, so I’ll try to describe how geneticists detect interbreeding in general.
I’ll look at the human genome, and I’ll start at the beginning – a very good place to start. This largely comes from Who we are and how we got here, and the following quotes come from that book. The human genome consists of a double chain of 3 billion nucleobases, adenine, cytosine, guanine and thymine. That’s 6 billion bases (often called letters – A, C, G and T) in all. Genes are small sections of this base chain (called DNA), typically a thousand or so letters long. They’re templates or codes for building proteins of many and varied types for doing many different kinds of work, although there are segments in between made up of non-coding DNA.
Researchers have been able to ‘read’ these letters via machinery that creates chemical reactions to specific DNA sequences:
The reactions emit a different colour for each of the letters A, C, G and T, so that the sequence of letters can be scanned into a computer by a camera.
What anthropologists want to focus on are mutations – random errors in the copying process, which tend to occur at a rate of about one in every thousand letters. So, about 3 million differences, or mutations, per genome (3 billion genes, coding or non-coding). But genomes change over time due to these mutations and each individual’s genome is unique. The number of differences between two individuals’ genomes tells us something about their relatedness. The more differences, the less related. And there’s also a more or less constant rate of mutations:
So the density of differences provides a biological stopwatch, a record of how long it has been since key events occurred in the past.
As Reich recounts, it was the analysis of mitochondrial DNA, the tiny proportion of the genome that descends entirely down the maternal line, that became a corner-stone of the out-of-Africa understanding of human origins, which had been competing with the multi-regional hypothesis for decades. ‘Mitochondrial Eve’ – a rather ‘western’ moniker considering that the Adam and Eve myth is only one of a multitude of origin stories – lived in Botswana in Southern Africa about 160,000 to 200,000 years ago, given the variability of the genomic ‘clock’ – the mutation rate.
So, what does this have to do with chimps and bonobos? Well, The exact detail of how Hvilsom et al proved that their (slightly) more recent interbreeding events occurred is hidden behind a paywall, and you could say I’m a cheapskate but the reality is I’m quite poor, trying to bring up seven kids and a few dozen grandkids in a home not much bigger than a toilet, so… but truthfully I’m just getting by, and I just want to know in general the techniques used.
First, they have to find ancient specimens, I think. But, in a video referenced below, they raised the question – Can we ‘excavate’ ancient DNA from modern specimens? We’ve learned that many modern humans have a certain percentage of Neanderthal DNA, say around 2%, but each person’s 2% may be different. Aggregating those different segments can, if we analyse the genomes of enough humans, create a whole Neanderthal genome, though not one of any Neanderthal who ever lived! At least that’s how I’m reading it, in my dilettantish way. So what exactly does this tell us? I’m not at all sure – it’s a relatively new research area, and completely new to me.
The presenter of this video uses the heading, at least at the beginning of his talk, ‘A little Archaic introgression goes a long way’. So now I need to know what introgression means. A quick look-up tells me it’s:
‘the transfer of genetic information from one species to another as a result of hybridization between them and repeated backcrossing‘.
I’ve bolded two key words here. Hybridisation, in mammals, is ‘breeding between two distinct taxonomic units’. Note that the term species isn’t used, presumably because it has long been a questionable or loaded concept – life just seems too complex for such hard and fast divisions. Backcrossing seems self-explanatory. Without looking it up, I’d guess it’s just what we’ve been learning about. Canoodling after speciation should’ve ruled canoodling out.
But, looking it up – not so! It’s apparently not something happening in the real world, something like backsliding. But then… Here’s how Wikipedia puts it:
Backcrossing may be deliberately employed in animals to transfer a desirable trait in an animal of inferior genetic background to an animal of preferable genetic background.
This is unclear, to say the least. How could an animal, even a human, deliberately do this? We could do it to other animals, or try it, based on phenotypes. We’ve been doing that for centuries. What follows makes it more or less clear that this is about human experimentation with other animals, though.
Anyway, I’m going well off-topic here. What I wanted to do is try to understand the proof of, or evidence for, bonobo-chimp interbreeding. I accept that it happened, well after the split between these two very similar-looking species. What could be less surprising? Along the way I’ve been reminded inter alia, of homozygous and heterozygous alleles, but I’ve been frustrated that straightforward information isn’t being made available to the general public, aka myself. I’ll pursue this further in later posts.
Jacinta: What a mess. Phenotype isn’t everything my friend. To a bonobo, a chimp probably looks like a neanderthal – a real bonehead… They probably only had sex with them out of pity. ‘Boys, we’ll show you a good time – like you’ve never had before.’

love, monogamy, marriage and bonobos
To claim that a union founded on convention has much chance of engendering love is hypocritical; to ask two spouses bound by practical, social and moral ties to satisfy each other sexually for their whole lives is pure absurdity.
Simone de Beauvoir, The Second Sex, p 478.
Discuss…
Canto: So we’re reading Beauvoir’s The second sex, inter alia, and though things have changed a bit in the WEIRD world over the past seventy-odd years, the section titled ‘The Married Woman’ does give something of a historical perspective, via the writings of such males as Montaigne, Balzac, Diderot and Kierkegaard, on the perceived differences between love and marriage and the problems that arise from these differences.
Jacinta: Yes, and marriage and monogamy are something of a mystery, historically, in spite of arguments such as those of Ferdinand Mount in The subversive family, that they are a more or less natural element of human life. We don’t know much about the state of affairs of early Homo sapiens or their ancestors and extinct cousins vis-a-vis monogamy. We do know that our closest living relatives, the bonobos and chimps, aren’t monogamous. And as to the claim, made by some, that humans are meant to be monogamous, that’s of the same type as, say, that humans are meant to be bipedal. No, it’s just something that we evolved to be, as some, but not all of us, socially evolved to be (more or less) monogamous.
Jacinta: The question is when? I suppose an obvious answer is when the concept of property became important, and the handing down of property to offspring. So that families started to become powerful rather than individuals. The beginnings of agriculture?
Canto: Some say division of labour may have played a part, though I’m not sure why…
Jacinta: Scientific American has an interesting online article from a few years ago reporting on studies that ‘aimed to find the best explanation for monogamy among three persistent hypotheses: female spacing, infanticide avoidance and male parental care’. So female spacing is just what it says: according to SciAm:
The female-spacing hypothesis posits that monogamy arises after females begin to establish larger territories to gain more access to limited food resources and, in the process, put more distance between one another. With females farther apart, males have a harder time finding and keeping multiple mates. Settling down with a single partner makes life easier, reducing a male’s risk of being injured while patrolling his territory and enabling him to ensure that his mate’s offspring are his own.
Canto: Females began to do that? In the bonobo world, female closeness was the key to their success – the females I mean, but perhaps also bonobos in general. It seems to me more likely that women would work in teams, helping each other to find and exploit resources, or am I being too hippy-happy-clappy?
Jacinta: Yeah maybe, but I note also the assumption here that males would have a hard time keeping multiple mates – the assumption being that early humans were already male-dominated.
Canto: Yes that quoted paragraph is all about the males… though to be fair most primate species are male-dominated. Still, one can’t assume…
Jacinta: Well, the proponents of this hypothesis did a statistical analysis of couple of thousand mammalian species, and found, apparently, that they started out solitary, but many, or some, switched to monogamy during their evolutionary history. How they proved that I’m not sure. They claimed that ‘monogamy most frequently occurred in carnivores and primates…’
Canto: Hang on. Isn’t it true that most primates are not monogamous?
Jacinta: Ahh, you’re probably thinking only of apes. There are hundreds of primate species, and they’re still being discovered. Three more were added in the last couple of years.
Canto: Shit! It’s all so hard to keep up with.
Jacinta: Lorises and lemurs, tarsiers and hatfuls of monkeys. Simians and prosimians, old world and new world, greater and lesser apes, etc. And actually, most primates are monogamous.
Canto: Well, I don’t think we should let it bother or constrain us. If we don’t feel monogamous, I mean individually speaking, we don’t have to be so.
Jacinta: But there are social constraints. They’ve loosened, no doubt, in the WEIRD world, but they’re there still. Besides, it’s convenient to settle down with one person, especially as you get older. It’s hard work trying to impress one partner after another into canoodling, what with rivalries and jealousies, and children who end up not knowing who’s what.
Canto: Well, yes – it does spice up life a bit, but too much spice can be overly acidic, or something. Still, I cling hopefully to the bonobo way…
Jacinta: Anyway, let’s get back to the second hypothesis – infanticide avoidance. I don’t think there’s much in this, re humans, but here’s the rationale:
Primates are uniquely at risk for infanticide: they have big brains that need time to develop, which leaves babies dependent and vulnerable for long periods after birth. And the killing of babies has been observed in more than 50 primate species; it typically involves a male from outside a group attacking an unweaned infant in a bid for dominance or access to females.
I suppose early hominids lived in smallish groups, like troupes of other primates, and I never considered that there’d be an alpha male among them, but I suppose it makes sense. But the bonobo part of me is in denial….
Canto: Well, warfare goes back a long way and capturing and raping women has always gone along with that, and it’s often been about capturing and expanding territory – e.g. Putin and Ukraine – and in those earlier times when resources were scarcer and harder-won, children, that’s to say the children of the defeated, would’ve been a burden. And the winners knew they could make more of their own with the captive women. It’s all quite plausible. I saw it in Empress Ki!
Jacinta: Hmmm. Having it off with captive women – essentially rape – doesn’t really fit with monogamy. In those Korean historicals you love there are wives and also concubines, and your alpha-maledom would be defined by the number of concubines you commanded, I’m guessing. So the male parental care hypothesis is most palatable to us moderns, I hope. Here’s what the SciAm site says:
When a baby becomes too costly in terms of calories and energy for a mother to raise on her own, the father who stays with the family and provides food or other forms of care increases his offspring’s chances of survival and encourages closer ties with the mother. A related idea… holds that the mere carrying of offspring by fathers fosters monogamy. Mothers have to meet the considerable nutritional demands of nursing infants. Yet for primates and human hunter-gatherers, hauling an infant, especially without the benefit of a sling or other restraint, required an expense of energy comparable to breast-feeding. Carrying by males could have freed females to fulfill their own energetic needs by foraging.
Canto: Yes, that’s a much more Dr Feelgood hypothesis, but interestingly this assumes an understanding of the relationship between sex and offspring. Males wouldn’t want to be caring for someone else’s kids, would they? And I’m sure I read somewhere that even some cultures living today, or at least not so long ago, aren’t clear about that relationship.
Jacinta: Well, and yet I’ve heard that bonobo females try to control who their adult sons mate with, as if they have an inkling… Bronislaw Malinowski (the first anthropologist I ever heard of) claimed that Trobriand Islanders thought that males played no role in producing children, but that’s been found to be a bit questionable. Seems plausible to me though. And something to aim for.
Canto: One thing anthropologists seem to say nothing about in these reflections on monogamy is love. This eternal bonding force that unites Romeo and Juliet, Antony and Cleo, Sonny and Cher…
Jacinta: Yeah, hormones they say. And when offspring come along, a certain force of duty, often reinforced by the community, or the State. So the male parent ends up staying, not really knowing whether it’s because he wants to or not. And one of the forces, a principle force, is societal, or cultural. He sees pairings-off all around him, physically reinforced by separate houses, fenced in. It’s the ‘norm’. With bonobos, no physical or, apparently, ethical barriers have been erected against polyandry/polygyny – to use human terms that would be meaningless to them. Does that mean no love? Of course not – on the contrary, our cousins can still teach us a thing or two about love…

Canto: So bonobos have been called the ‘make love not war ‘ apes, a joke moniker in a way, but I’ve been thinking about that in an attempt to be more serious about love, fellow-feeling and all that stuff, in bonobos, humans, and other species.
Jacinta: Yes, the idea of ‘true love’, which involves some kind of eternal monogamy, and is seen as peculiarly human, and sells ye olde penny romances, is still with us, and whole governments are raised around it – the couple, the nuclear family and such. Of course, in the WEIRD world, there are increasingly diverse ‘household arrangements’, but they still generally involve separate, enclosed households. Ye olde hippy free love encampments, if they were anything other than an imaginary figment, seem as distant now as our connection with bonobos. A while back we read Ferdinand Mount’s 1982 book The Subversive Family: An Alternative History of Love and Marriage, a fairly well-reasoned defence of marriage and monogamy, and its glorious survival in spite of the free love mini-revolution, but of course he didn’t mention bonobos or speculate about the domestic arrangements of australopithecines.
Canto: Mount was – still is – a lifelong conservative, so his history was always going to be tendentious, and as you say, limited to more recent times, so it didn’t really address how we came to be monogamous, if that’s what we are. And just to set the scene with our loving cousins:
Bonobos do not form permanent monogamous sexual relationships with individual partners. They also do not seem to discriminate in their sexual behavior by sex or age, with the possible exception of abstaining from sexual activity between mothers and their adult sons.
Wikipedia entry: bonobo sociosexual behaviour
Jacinta: Conservatives wouldn’t be too happy about that sort of indiscriminate behaviour among humans, but they’d be hard pressed to argue that bonobos are ‘immoral’ or selfish, or dysfunctional and a behavioural threat to the well-being of their own society.
Canto: No, they’d probably just argue that they’re not humans and we have nothing much to learn from them. We’re 8 billion, after all, and they’re just a few thousand. We win! But I don’t think our success has much to do with our domestic arrangements. It presumably has more to do with the enlargement of our prefrontal cortex, and the causes of that, which were presumably numerous and incremental, may have also brought about an increasing division of labour along patriarchal lines.
Jacinta: Certainly our history, at least since it has been recorded, has been overwhelmingly patriarchal. Hunting as a largely male activity, as I believe it also is in chimps, could be kind of brutalising, as it’s a kill-or-be-killed activity at its worst.
Canto: Meanwhile bonobos have been evolving in their own way over the past few million years. Or not. I mean, they’ve been content to stay in the forest, in a pretty lush part of the Congo, consuming a very largely vegetarian diet, not exactly requiring a lot in the way of muscles and physical prowess. And get this, again from Wikipedia:
Bonobo clitorises are larger and more externalized than in most mammals; while the weight of a young adolescent female bonobo “is maybe half” that of a human teenager, she has a clitoris that is “three times bigger than the human equivalent, and visible enough to waggle unmistakably as she walks”
As they say ‘exercise makes the clit grow longer’. Dunnit?
Jacinta: Well, it’s true, bonobo females engage in genito-genital rubbing more than males do, and this seems to form the basis of female group dynamics, which has led to female dominance. Unfortunately in humans, clothing creates a major barrier to this activity, at least in public.
Canto: Ahh, the terrible price of civilisation. But what I’m interested in is the effect of female dominance. Yes, it’s mediated to a large degree by sexual play, and a general closeness, which we don’t seem to have the maturity to adopt, so obsessed have we been with sexual possessiveness and jealousy, to the point of stoning people – sorry, women – for adultery. Death by drowning was the punishment back in Hammurabi’s day, almost 4000 years ago. Under Ancient Greek and Roman law, women could be executed for adultery, while the men would rarely get more than a smacked bottom.
Jacinta: Actually, stoning is still a punishment, for both genders, in countries that apply strict Shari’ah law. But in the WEIRD world, where no-fault divorce is increasingly accepted, adultery has faded as an issue. And generally we’ve become more relaxed about sexuality in all its varieties, and more sceptical about ‘love’, of the everlasting and exclusive type.
Canto: Yes, and yet… love, whether it’s a human invention or not, or whether it’s just hormones – it really hurts. You develop this ridiculous passion for someone, her movements, her smile, her vitality – though she has as much interest in you as in a rotten egg. Or she takes a general interest but backs off when she senses your need. And that’s just ‘unrequited love’. Even when it’s a mutual passion it can sooner or later turn to shit. The quotes above are just three of thousands that could be mined from songs, stories, legends and our own lives. Great expectations, dashed, sublimated, given up on, nursed in solitude. A tension between the cult of individuality and its freedoms and the love that loves to speak its name, where those individuals go together like a horse and carriage, like fire and ice, Batman and Robin, Venus and Mars…
Jacinta: Well, humans do tend to overthink these matters, or over-feel them perhaps, what with our heightened sensibilities. And our civilisations have tended to push us towards exclusive ‘love relations’, and the concept of ownership:
You shall not covet your neighbor’s house. You shall not covet your neighbour’s wife, or his male or female servant, his ox or donkey, or anything that belongs to your neighbour. (Exodus 20:17)
So it’s not just that we’ve fallen for the myth of true love and the ideal partner – our society has created a monogamous reproductive norm, and for a good few millennia (not really so long in human history, but we know hardly anything about our sociosexual behaviour beyond the last 10,000 years or so) we’ve fallen in with it – leaving aside sultans, random monarchs and the odd billionaire entrepreneur. Our homes have, over time, become designed to largely rule out even extended family togetherness. Bonobos don’t have homes and they’re not particularly territorial….
Canto: Well, to change the subject, I’m interested in that description of bonobo clitorises. It sounds wild -so to speak. And of course it sounds very much like a penis. It all makes me think of the whole penis envy malarky of Freudian psychotherapy. Not a problem for bonobos, clearly. If we get our social evolution right, our female descendants in the non-foreseeable future (if that makes any sense) will be waggling those clits about most merrily.
Jacinta: Hah, makes a change from current-day ‘clitoridectomy’ aka FGM.
Canto: Well, they could give em a trim, like modern-day circumcision. Or have em shaped and coloured, like orchids….
Jacinta: Lovely. Interestingly, Simone de Beauvoir touches on this in The Second Sex, probably influenced by the penis envy ideas of the time. Writing of woman:
her anatomy condemns her to remain awkward and impotent, like a eunuch: the desire for possession is thwarted for lack of an organ to incarnate it. And man refuses the passive role.
No organ permits the virgin to satisfy her active eroticism; and she does not have the lived experience of he who condemns her to passivity.
the second sex, trans. C Borde & S Malovany-Chevallier, vintage books 2011
But in the WEIRD world, things have changed, or are changing, and hopefully girls are much more expert at playing the organ. Though, unlike bonobos, it’s largely done in solitude.
Canto: But do bonobos love each other, or just each others’ organs? It’s probably as uninteresting a question as What’s this thing called, love?
Jacinta: Well, that’s it, bonobos just get it together, not just for sex, but for safety in numbers, for huddling and cuddling, for play, for warmth, food-sharing and back-scratching. I doubt if they wonder if it’s really love, or how selfish or selfless they’re being. It’s their life – one of community rather than pairing off – as long as they can be left to get on with it.

Simone de Beauvoir, The second sex, 1949
erogenous zones, domination, submission, bonobos and other sexy stuff
Jacinta: So Simone de Beauvoir has a section in The second sex called ‘Sexual initiation’, which seems to me much influenced by all that Freudian stuff we’ve been exploring in Freud’s women, particularly all that clitoral versus vaginal malarky. However, she does try to get to the bottom of the physiological aspects rather than the psychological, which the Freudians (and many of their opponents) seemed to be stuck on. Still, she seems overly influenced by the passive-active distinction that Freud, especially in the early years, assumed as ‘natural’ vis-a-vis the female-male attitude to coitus.
Canto: Well, to be fair, in much mammalian coitus, the male ‘mounts’ and the female assumes the ‘lordosis position’, according to zoologists. It all appears a bit dominant-submissive to me.
Jacinta: Yeees, sort of, and this seems to have much to do with the evolved features of the sexual apparatus. Think of birds – the male jumps on top, wiggles around and that’s it, it lasts a couple of seconds. Consider that birds generally bond in lifelong pairs, with the odd bit on the side, and the males aren’t generally dominant, though it varies a lot species-wise, and birds, at least some species, are quite intelligent…
Canto: Yeah we don’t tend to think of the lifelong psychological effects of the physical act, or positioning, of sex in birds, or cats and dogs. We’re very speciesist that way.
Jacinta: Which reminds me of another story – actually a memory, of a dog we had, a female who regularly masturbated on top of her favourite fluffy toy, when she wasn’t ‘fighting’ with it all over the house. I can’t remember whether she’d been desexed or not, but clearly her erogenous zones were still intact. Was this clitoral or vaginal stimulation? Does it really matter? But of course for we humans it’s all so much more complex, apparently. Especially for us women. Here’s what Beauvoir has to say – and I sympathise to some extent:
The act of love [sic] finds its unity in its natural culmination: orgasm. Coitus has a specific physiological aim; in ejaculation the male releases burdensome secretions; after orgasm, the male feels complete relief regularly accompanied by pleasure. And, of course, pleasure is not the only aim; it is often followed by disappointment: the need has disappeared rather than having been satisfied. In any case, a definitive act is consummated and the man’s body remains intact: the service he has rendered to the species becomes one with his own pleasure. Woman’s eroticism is far more complex and reflects the complexity of her situation…. instead of integrating forces of the species into her individual life, the female is prey to the species, whose interests diverge from her own ends; this antinomy reaches its height in woman; one of its manifestations is the opposition of two organs: the clitoris and the vagina.
The second sex, pp 394-5
Canto: Yes… well, if dogs don’t much care if it’s clitoral or vaginal pleasure, why should women? It’s all an erogenous zone, some parts more than others maybe, but when the ‘act is consummated’, who cares? And the remark that ‘the female is prey to the species’ presumably refers to pregnancy and all its attendant issues. Beauvoir was writing before the contraceptive pill, which changed so much, at least in the WEIRD world.
Jacinta: Well, yes but there’s the whole issue of teen pregnancy, due to rape, ignorance and the like, and abortion and its enemies. Look at the USA today, still messed up about this issue. But, yes, this clitoris-vagina stuff is largely a red herring to me.
Canto: Yes it all smells a bit fishy.. oh sorry that was a bit below the belt…
Jacinta: Haha I recall an American sex video actor saying all her male co-performers’ dicks stank of marihuana – which may or may not be worse depending on your taste. But speaking of sex, there is an obvious imbalance in the sex game. How often do women rape men? Or even ‘coerce’ men into having sex. And think of gang rape. And the horrific consequences for women. And of course most men don’t rape, or even give it a moment’s thought – at least I hope they don’t – but I know the danger is often on the minds of women when they’re having a night out.
Canto: Safety in numbers, and that seems to be the bonobo way too, and getting back to other mammals again, it’s generally the case – think dogs, horses, any four-legged beastie – that the male mounts the female. Often from behind, like sneakily, creepily. Males on top, and females more or less taken unawares, more or less unwillingly. It seems like the urge to copulate invariably comes from the male.
Jacinta: Yes, evolution appears to have worked it that way, though social evolution can turn this around, at least somewhat. Not just safety, but power in numbers, that seems to be the bonobo way.
Canto: So how exactly do bonobos deal with the sex issue? I’d like some details. I know they engage in regular stimulation of each others’ erogenous zones, aka masturbation, but what about actual copulation, for the purpose of reproduction, though presumably they don’t make the connection. And when did we humans make the connection, when it comes to that?
Jacinta: Well bonobos reproduce at the same rate as chimps, despite all their sexual shenanigans. Humans differ from our primate cousins in that we don’t ‘come into season’ with ‘attractive’ pink swellings, which have an effect on the males, that’s both visual and probably chemical – pheromones and all.
Canto: And if we did – I mean if you females did – it might well be covered up, not only with clothing but deodorants and the like. I wonder if there’s any vestigial elements of being ‘in heat’. as they say, in humans.
Jacinta: Well this is where we move onto hormones. Here’s a quote from a sexual health website, which is pretty reliable:
Medical experts associate changes in sex drive with changes in the ratio of estrogen and progesterone, hormones that are produced by the ovaries. These shifts occur at different phases of your monthly cycle. During your period and for a few days after, the concentration of both hormones is low, resulting in less sexual desire. By the time ovulation rolls around, estrogen peaks, naturally increasing libido. Once the process of ovulation wraps up, there’s a boost in progesterone production, and you might notice a dip in your sex drive.
Canto: Ah yes, menstruation – I don’t recall Freud saying much about that. Do bonobos menstruate?
Jacinta: Do bears shit in the woods? We should do a whole interaction on the menstrual cycle, for your benefit. Anyway, here’s a useful brief guide to bonobos and chimps:
- Bonobos are sexually receptive for a large portion of their reproductive cycle, even when not near the time for ovulation.
- This trait has sometimes been called concealed ovulation because the male has no clear signal for the optimum time for mating.
- Bonobos also engage in sex in non-swelling phases of their cycle in about 1 out of 3 copulations.
- Chimpanzee females tend to be sexually active only during their maximum swelling phase.
Canto: Right. Uhhh, no mention there of menstruation. Forgive my ignorance but what’s the difference/connection between ovulation and menstruation?
Jacinta: Okay here’s the story with us humans. Ovulation starts at puberty. It’s when an egg is released from one of the ovaries (we have a left and right ovary). You can say this is when we’re fertile, when we’re liable to get pregnant. Ovulation occurs at around day 14 of the 28-day menstrual cycle, on average. The cycle starts, and ends, with that thing called ‘the period’, when material from the endometrium, the lining of the uterus, is shed, along with blood and other yucky stuff. You can imagine the psychological impact that might have on girls when they’re not prepared for it. It can be a real trauma. So menstruation strictly refers to the whole cyclical process, but it’s often used to refer to that flushing out ‘period’. All of this is mediated by hormones. Estrogen is the main builder of new endometrium – the biochemistry of it would require a whole other conversation.
Canto: Yes that’s enough for now, but it seems that oestrogen also boosts libido…
Jacinta: Yes, that’s important, the urge to copulate doesn’t just come from the males. And this physiological stuff seems like solid ground after all the flights of psychoanalysis we’ve been trying to get our heads around recently.
Canto: And we haven’t yet gotten onto what has been made of Freudian and post-Freudian theory by the likes of Lacan, Kristeva, Irigary, Cixous, Derrida, Deleuze, and of course Guattari, among many others…
Jacinta: Yeah, mostly French – funny that. It seems Freud’s influence has waned, though, in the 30 years since Freud’s women was published. The broad Freudian notion of the unconscious – rather than the unconscious processes that go on through our nervous and endocrine systems – has been buried, it seems, by neurological advances, which, as Robert Sapolsky points out in his book Behave, have been fast and furious in the 21st century. But that period, and that physical and metaphysical region centred around Vienna when Freud was active in the first decades of the 20th century, was very fruitful, and in many ways revolutionary. Anil Seth, one of today’s leading researchers into human consciousness, paid tribute to it in his book Being you:
In the fluid atmosphere of Vienna at that time, the two culture of art and science mingled to an unusual degree. Science wasn’t placed above art, in the all too familiar sense in which art, and the human responses it evokes, are considered to be things in need of scientific explanation. Nor did art place itself beyond the reach of science. Artists and scientists – and their critics – were allies in their attempts to understand human experience in all its richness and variety. No wonder the neuroscientist Eric Kandel called this period ‘the age of insight’, in his book of the same name.
Canto: Well, that’s a nice conciliatory note to end this conversation on.
