Naked bonobos?
Dear Editors
I agree with much of “Bonobo Fides” (Pathfinders, January), but I would like to take issue on a few significant points.The author follows the sources on which he relies in placing too much emphasis on the power of the “combined females” as a deterrent to male violence. Bonobos of both genders keep the peace mainly by using friendly activities – grooming, play and sharing food as well as frequent sex – to soothe the tensions that might lead to violence. (They don’t “run off into the bushes,” by the way, but have sex in plain view of others. Here the author is mixing up bonobos with humans.) It also helps that with bonobos, unlike chimps, the males can’t tell which females are ovulating, so they are unable to compete to sire offspring.
Bonobos may “live largely as vegetarians,” but they do have a taste for meat. “Like chimpanzees, they are ready to grab and eat small antelope infants. They eat flying squirrels and sometimes earthworms” (Demonic Males, p. 216).
Unlike chimps, however, they never eat monkeys. Instead, bonobos play with monkeys as though they were pets. Monkeys are terrified of chimps but show no fear of bonobos. Apparently, this reflects a cultural taboo against killing and eating fellow primates, and such a taboo may be one reason why bonobos rarely attack and never kill one another. (Local humans have a similar taboo against hunting bonobos.)
Would chimps adopt bonobo behaviour in a bonobo environment and vice versa, “given long enough”? I think this is an exaggeration. Bonobos are a distinct species, not a kind of chimpanzee. (“Pygmy chimp” is a misleading term that dates from the time when this was not yet recognized.) To the extent that bonobo sociality is a product of genetically determined characteristics like large sexual organs and always being on heat, environmental change can affect it only to a limited degree. Over a period long enough for evolution to occur the bonobo might lose these characteristics, but then it would no longer be a bonobo!
Especially for socialists, the good news about the bonobo is how close it is to man. We have 98.7 percent of our genes in common with the bonobo. That’s the same figure as for the chimpanzee, but in numerous respects we – and also, according to physical anthropologist Adrienne Zihlman, our proto-human ancestors living in Africa 3 to 5 million years ago – are closer to bonobos than to chimps. This applies, for example, to bodily proportions, facial appearance (look at the photos in Frans de Waal and Frans Lanting, Bonobo: The Forgotten Ape), posture (bonobos walk upright much of the time, along trails that they make themselves), and of course sexual functioning. In 1967 Desmond Morris gave ammunition to the “human nature” objectors to socialism by “exposing” man as The Naked Ape. It’s not quite so bad if we change that to “the naked bonobo”!
Only a few thousand bonobos are left, all of them in the war-torn Congo. Their extinction would be a tragedy for man too, not least because they are living proof of the positive side of our evolutionary heritage.
