Evolutionary biology, testosterone and bonobos

this is the first of a 22-part slide show on the topic – hormones don’t rate a mention!
Canto: So I think we need to get back to another obsession of ours – bonobos and how we can harness a bit more bonoboism for human purposes. We’re currently observing, horrified, as Russia’s alpha male chimp flips out on his own testosterone, perhaps….
Jacinta: Yes, it could well read like something out of Jane Goodall – a long-term alpha male, who has done reasonably well in holding his troupe together by inordinate bullying, random slaughter and regular breast-beating, and by smart alliances, suddenly endangers everything in attempting to take over another troupe…
Canto: And having read three books on the trot, referenced below, on China and its all-male thugocracy, it’s more than tempting to cast that thugocracy in chimpian terms – alpha male after alpha male after alpha male.
Jacinta: Yes, I’ve long considered how best to rename the soi-disant Chinese Communist Party (CCP), arguably the most absurd misnomer in the known universe. I considered the Chinese Fascist Party, but that seems a bit ‘trendy’, and to call it simply The Party seems too bland, neutral, and even festive. But to call it the Chinese Testosterone Party – that fits the bill perfectly. I really really want that to catch on in the WEIRD world. So anyway, with the evidence mounting that female leadership leads to better outcomes, politically, socially and, I hope, sexually – though we’ve been a bit nervous about that tediously sensitive issue – how can we speed up the trend towards human bonoboism?
Canto: It’s hard, especially when all these macho shenanigans bring out my own most bloodthirsty revenge fantasies. But I’ve been wondering about hormones: Are there any hormonal differences between chimps and bonobos that might help to explain the bonobo turn towards female-female bonding and control of males – and the freewheeling sexual play within bonobo society?
Jacinta: You mean – could we control and transform our human world through some kind of hormone replacement therapy? Sounds promising.
Canto: We’ll here’s some food for thought re males versus females, and not just in humans:
Empathy is our ability to understand how others are feeling, and men are less able to do this than women, across cultures. This is a widely replicated and consistent finding, and it’s not true just of human males and females. In chimpanzees, bonobos, gorillas, elephants, dogs and wolves, researchers have observed that males engage in lower rates of behaviours related to empathy, like caregiving, cooperating, helping and comforting.
Carole Hooven, Testosterone, p159.
Jacinta: So the question is – is there a hormone we can take for that? Sadly, it’s never that simple.
Canto: Sure, but anyway, let’s ask Dr Google. Hmmm, top of the page:
There is some evidence that high levels of estradiol and progesterone are associated with low levels of aggression
Jacinta: That’s enough for me. Compulsory high-level doses for all males. Overdoses in fact. They either die or shut the fuck up.
Canto: So there’s a university textbook, Principles of social psychology, which has a section, the biological and emotional causes of aggression, and of course Hooven writes a lot about aggression and testosterone in humans and other animals. There’s just so much to dig into here. For example, pair-bonding male birds and other animals, such as bonobos, who have more of a share in child-rearing, have lower testosterone levels than those in social situations where there is a greater separation between males and females. Arguably that is the case in agricultural societies as opposed to hunter-gatherers.
Jacinta: So much easier to change hormone levels by just stuffing them into people’s bodies than by changing behaviour, though, surely. Can’t you just add them to the water supply?
Canto: That might be possible, especially if we lived in a thugocracy.
Jacinta: Hmmm, it gets more and more confusing.
Canto: What’s interesting about the findings is the chicken-egg issue. Does the gradual social evolution of male caring – if that’s what’s happening – reduce hormone levels or vice versa? I would hypothesise that it’s the caring that’s affecting the hormone levels, but how to test this?
Jacinta: Seriously, testosterone plays a huge role in our development, physiologically to take it to its most basic level. It makes for more athleticism, and probably for more of the competitive urge that leads to that obsessive athleticism, and bodybuilding claptrap. Somehow it makes me think of Mr Pudding, and his caricaturish experience of first being bullied by Charles Atlas types, and then learning a few martial arts-type skills to get revenge, with the end result of controlling a whole nation, and leading a military to rape and murder women and blow kids to bits in Ukraine. Testosterone has a lot to answer for.
Canto: And yet. Look at bonobos. Look at Scandinavia. The beast has been tamed, in a few pockets of our universe.
Jacinta: Do aliens have hormones, there’s a question.
Canto: Yeah we first have to answer the earthling question – are there aliens in the universe?
Jacinta: But haven’t quite a few humans been kidnapped by aliens?
Canto: Ha, oh yes, the ones who escaped…. but all the missing persons…
Jacinta: Returning to Earth, the hormone issue, and possibly even the neurophysiology issue, these raise the questions of masculinity and femininity – which Hooven explores from an endocrinological perspective – does a woman with a high testosterone level have a disqualifying advantage over another ‘normal’ woman, in running, jumping, throwing and lifting?
Canto: Hilariously – depending on your perspective – this has become a minefield in the world of sport and athletics. Hooven cites an athlete, Caster Semenya (and I know v little about this topic) who had a habit of blitzing the field in running events a decade ago – in fact from 2009 to 2018. Unsurprisingly, I would say, she had ‘suspiciously’ high testosterone levels (which of course would never have been measured before the 21st century), so complaints were made. Was this woman really a man? Which raises obvious masculinity and femininity questions…
Jacinta: Which, just as obviously, should be quashed by – fuck, she’s fast, that’s so fantastic! Go, girl!
Canto: But I suppose there’s a legitimate question – do abnormal levels of x give you an advantage?
Jacinta: Yeah, like long legs, in running? Shouldn’t leg length be subject to restrictions?
Canto: It’s a good point. We want to think maleness and femaleness are distinct, but we tend to think in terms of averages – the average female is 80% of the mass of the average male, the average male produces x more testosterone than the average female, etc, but there’s enormous variation within each gender, and that’s genderbendingly problematic for more than just athletics officials.
Jacinta: Anyway, just how important is endocrinology for a future bonobo world? Should we be focussing on promoting estradiol and progesterone rather than femaledom? Should we be screening politicians for the best hormonal balance rather than the best policies?
Canto: Ah but if my previously mentioned hypothesis is correct, we should be screening potential ‘leaders’ for their caring and sharing, which will lead to a greater expression of the ‘good’ hormones.
Jacinta: Yes, good for a society in which aggression has more serious consequences than it had in the past, what with WMDs and the like – the slaughter of women for their ‘contemptuous’ flouting of dress codes, the slaughter of ethic communities for their insistence on a modicum of independence. Aggression with a massive state apparatus behind it, and more effective weaponry than ever before. But how do we rid ourselves of these aggressive states without aggression? How do we even defend ourselves against them without aggression?
Canto: Maybe we’re just wanting too much too soon. I note that we’re getting more female political leaders than in the past, though they tend so far to be countries with relatively small populations – Scotland (our birth country), Scandinavian countries, New Zealand, Taiwan, the Baltic States… and, as with bonobos, it’s not just the alpha females, it’s the status of the whole female sex that makes the difference.
Jacinta: Yes, if we had but world enough, and time….
