The Gendered Ape, Essay #6
THOSE EMBARRASSING BONOBOS!
It’s not always easy to talk about bonobos at academic gatherings. There is no issue with fellow primatologists, who are used to straightforward descriptions of sexual behavior and know the recent evidence. But it’s different with people outside my field, such as anthropologists, philosophers, or psychologists. They become fidgety, scratch their heads, snicker, or adopt a puzzled look. Why do bonobos stump them?

Here standing upright, an adult female (left) and an adolescent male. Since bonobos are genetically equally close to us as chimpanzees, they deserve the same attention in relation to human evolution.

One reason for the discomfort is excessive shyness about erotic behavior, which bonobos exhibit in all positions that we can imagine, and even some that we can’t. Moreover, these apes do it in all partner combinations. People assume that animals use sex only for reproduction, but I estimate that three-quarters of bonobo sex has nothing to do with it.
But there is a deeper reason why bonobos are the black sheep of our extended family despite being as close to us as chimpanzees. They fail to conform to the traditional model of the human ancestor. Most evolutionary scenarios of our species stress male bonding, male dominance, hunting, aggression, and territorial warfare. This is how our species conquered the earth, it is thought.
Chimpanzee behavior, which can be quite violent, lends support to this narrative. This ape is therefore happily embraced as a model. The peaceful, female-dominated bonobo, on the other hand, doesn’t fit. The species is sidelined, such as in “The Better Angels of Our Nature,” in which Steven Pinker calls bonobos “very strange primates.” And Richard Wrangham, in “The Goodness Paradox,” portrays them as an evolutionary offshoot, who “have gone their separate way.” In other words, bonobos may be delightful apes, they are bizarre and irrelevant. Let’s just ignore them!
According to pioneering fieldworker Takayoshi Kano and his students, bonobo groups in the forest regularly “mingle” and “fuse” without any fighting. They share food between communities and occasionally adopt orphaned youngsters from their neighbors. All of this presents a huge contrast with chimpanzees, which know only various degrees of hostility between communities.
My own studies made matters worse by describing bonobos as polyamorous flower children. Intense erotic contact, known as GG-rubbing, is common among females. It allows them to form the powerful sisterhood that is the glue of their society.
Since the species has thrown a huge wrench into popular origin myths, we see regular attempts to revise our views, such as when journalists or political pundits tout observations of bonobo aggression and predation. Unfortunately for them, predation means very little. In biology, it falls under feeding behavior, not aggression. Anyone who has been chased by a bull realizes that a species’ diet says little about its aggressiveness.
But it’s true that bonobos occasionally fight. In fact, their extensive sexual activity would make no sense if their society were free of social tensions. The main purpose of this activity is to keep the peace. “Make love - not war” is a bonobo slogan.
Until now, however, there is not a single observation of one bonobo killing another, neither in captivity nor in the wild. A recent count of lethal aggression among bonobos and chimpanzees in Africa listed 152 incidents. Of those, only 1 concerned bonobos, and this was a suspected killing, not an observed case. All other cases concerned chimpanzees.
Bonobos may be genetically equally close to us as chimpanzees, but anatomically they are more like us. Harold Coolidge, the American anatomist who gave the bonobo its species status, already concluded in 1933 from his dissection of a bonobo corpse that this ape “may approach more closely to the common ancestor of chimpanzees and man than does any living chimpanzee.”
I had to think of this when “Ardi” was discovered, a 4.4 million-year-old Ardipithecus fossil from Ethiopia. Her unusually small blunted canine teeth indicated that she was relatively peaceful. The discoverers could only think of chimpanzees as a comparison, however, when they concluded that Ardi’s physique set her apart from her ape forebears. As usual, the bonobo was overlooked.
With their long legs and frequent upright gait, however, bonobos resemble our immediate ancestors more than any other living ape. Not only does Ardi look very much like an upright bonobo, her assumed peacefulness also brings bonobos to mind.
But we’ll have to wait for a new generation of anthropologists before they will dare to contemplate that perhaps we descend not from a blustering chimp-like ancestor but from a gentle, empathic bonobo-like ape.

In this week’s eSkeptic, world-renowned primatologist Frans de Waal, responds to a recent New Yorker article on bonobos, in which primate politics, both left and right, once again muddled the science.

Could it be that the more accommodating our #environment is, the more we lose the ability to take care of ourselves? Could there be importance in the latrine communication of European rabbits that shifts along a rural-to-urban gradient? Can that express the upcoming shift of humanity into The Great Reset?

"The unbelievable power of nature; how stress guides animals and plants", puts forward the notion that the concept that we call "Stress" is not the evil villain we have been made to believe, instead is an integral part of life, often poorly represented and misunderstood.

Madlen Ziege is an active Biologist since 2009. Her last name "Ziege" in German translates to "Goat" in English; perhaps she was pre-determined to be a Biologist.

She has worked and studied in #Germany, #France, #Mexico, #Canada, #Japan and #Tasmania. Specializing in the #behaviour of #animals and #ecology of #plants, Madlen created the "urban to rural gradient", She has written 2 books and has authored over 30 scientific publications.

The original reason she wanted to become a Biologist was to learn to connect to nature and reality. Madlen now realizes that the scholastic approach to #biology often severs that connection and creates generations of numb scientists disconnected from reality, who are more than glad to work for big pharma and harm life in the process.

She now even questions while being on the board of directors for an organization that aims to protect wildlife against the ill effects of GMOs and #pollution, if environmentalism is nothing more than an extension of scholastically trained narcissism.

Completing her PhD in 2016, Madlen suffered massive #health issues. She suffered from Hormonal imbalances, hair-loss, anxiety, depression and eating disorders. The unfortunate reality is how common these health symptoms are amongst post-Docs!
