male aggression – it’s everywhere

Canto: Okay, let’s look at other cetaceans. There are 89 species, so we can’t cover them all. There are toothed and baleen types, but all dolphins and porpoises are toothed. There are river dolphins and oceanic dolphins, and in terms of size, cetaceans range widely, so that we have names like northern right whale dolphin, southern right whale dolphin, false killer whale, pygmy killer whale and various types of humpback dolphin as well the humpback whale. So it might be that they’re as culturally various as humans. I’ll limit my examination, then, to four or five well-known species, with no pretence that any of them typify the whole.

Jacinta: Yes, when we talked about dolphins before, it was the common bottle-nose dolphin, right?

Canto: Essentially yes, and I’ll pick some of the best known cetaceans, avoiding those most endangered, because they’ll probably be the least studied in the wild. First, the humpback whale, which is a rorqual. Rorquals represent the largest group of baleen whales, and of course humpback whales are an iconic and fairly well researched species, as whales go. And one immediately interesting fact is that the females are on average slightly larger than the males.

Jacinta: Size usually matters.

Canto: And they can live up to 100 years. But let’s talk about sex, or courtship as the Wikipedia article on humpbacks charmingly describes it. You’ll be happy to know that humpbacks are polyandrous – that’s to say, females mate with many males during their breeding season. This is generally seen as the opposite of polygyny – one male mating with many females. In fact polyandry is more often seen in insects than in any other life forms. Humpbacks have even been known to have it off with other species. Wikipedia calls it hybridisation. There’s apparently a humpback-blue whale hybrid out there.

Jacinta: I assure you that when females rule the world – in nevereverland – any attempt to employ ‘euphemisms’ for fucking will be punished by instant castration.

Canto: Well you’ll also be amused to know that males fight over females.

Jacinta: How very unsurprising. But at least they sing, which almost compensates.

Canto: Yes, males and females vocalise, but the long, complex and very loud songs are produced by males. It’s believed that they help to produce estrus in the females.

Jacinta: The correct term is fuck-readiness. 

Canto: In fact, researchers only think that because only males produce the complex songs. It’s a reasonable inference, but it could be wrong. Some think that the songs might be used to prove the male’s virility to the female, to make him more attractive. This supposedly happens with birdsong too.

Jacinta: Trying to think of human equivalents. Rocks in the jocks?

Canto: Oh no, too chafing. Being a good cook helps, I’ve found. But what with the obesity epidemic, that’s a balancing act. Anyway, those humpback boys put a lot of energy into their songs, which sometimes last for over 24 hours. Animals of one population, which can be very large, sing the same culturally transmitted song, which slowly changes over time. All interesting, but probably not much of a model for us. I can barely swim.

Jacinta: Well yes, it’s hardly sing or swim for us, but let’s turn to other cetaceans. What about blue whales?

Canto: Well it’s interesting to find that most websites don’t even mention their social life – it’s all about their ginormity, their big hearts, and their feeding and digestion. It took me a while to discover that they’re solitary creatures, which I suppose is common sense. Hard to imagine a superpod of blue whales out in search of a collective meal. They do sometimes gather in small groups, presumably for sex, and of course there’s a mother-calf relationship until maturity. As with humpbacks, the females are a bit larger than the males. What would that be about?

Jacinta: Well, some researchers (see link below) have discovered that male humpbacks favour the largest females, so there’s presumably sexual selection going on. And of course, they fight over the biggest females.

Canto: Well you can’t blame them for being macho. It be nature, and what do please gods.

Jacinta: Oh no, let’s not go there. Anyway, the largest females produce the largest and presumably healthiest offspring. They also found that the older females make the best mothers, which I’m sure is generally the case in humans too, mutatis mutandis. 

Canto: So in conclusion, these mostly solitary creatures, whether they be cetaceans or primates, can’t be said to be patriarchal or matriarchal, but the males still manage to be more violent, or at least more cross with each other, than the females.

Jacinta: But it doesn’t have to be that way, hence bonobos.

Canto: Yes, but that makes me think. I hear that bonobos use sex to ‘ease tensions’, among other things. Tensions hints of violence, or at least anger. I’m wondering if that anger comes mostly from the males, and if the use of sex to dissipate that anger comes mostly from the females.

Jacinta: That’s a good question. There’s a site, linked below, which sort of looks at that question. It cites research showing that female bonobos gang up on male aggressors. The researchers found an absence of female-on-female aggression (perhaps less so than in the human world). According to this site – which may not be wholly reliable, as it’s really about humans and nightlife behaviour – female bonobos bond in small groups for the specific purpose of keeping males in line. How do they know that? They might be arguing from girl nightlife behaviour. I mean, who’s zoomin who?

Canto: The general point though is that among bonobos, males are more aggressive than females. Which isn’t to say that females can’t be aggressive, and not just in a defensive way.

Jacinta: This website also mentions something which is the general point of all our conversations on bonobos and humans and sex and well-being. It’s worth quoting in full:

Anthropological data analyzed by neuropsychologist James Prescott suggests societies that are more sexually open are also less likely to be violent. The key to understanding this correlation, however, is that it’s the society as a whole that is more sexually open and not just a small percentage of individuals.

Canto: That’s a good quote to get us back to humans. We need to look at this matter more closely next time. And the next and the next.
