Lisala was one of the bonbos who was very sick; they pulled her out of group 3 when they saw she couldn’t breathe, and brought her to the vet block. She was another one of the bonobos we have known since she was small. So every day I would drive Anne Marie, the vet, nuts by asking her about 50 times about Lisala. She was on oxygen for a while, her breathing was so constricted.

But she made it and Brian figured while she was in the building all day he’d use her for the test. The test is whether Kasongo would open a door using a bonobo key to let Lisala in to share food with him. Most scientists think that only humans will give something in exchange for nothing (altruism) but Brian has an inkling bonobos might do it.


Alas for the Kasongo/Lisala trial, Kasongo unlocked the door and let Lisala in, she went straight for the food and pushed her bottom in the air so Kasongo could have sex with her while she ate all the food. I’m not sure if that’s altruism. Sounds more like my study, food for sex …

We still need more than $20,000 for bonobo food – please help if you can. www.friendsofbonobos.org/support.htm or lolayabonobo.wildlifedirect.org

Food for Sex

someone in the comments asked me what we were doing in congo and now i’m pleased to introduce our new study: food for sex. it’s no secret that whenever there is food around, bonobos have sex. to ease the tension, and to stop fighting – in chimps – the dominant gets the food and if anyone else tries to take it, he beats them up. in bonobo, there seems to be a more egalitarian way of doing it and when there’s food around, especially EXPENSIVE food, like green apples flown in from south africa at $100 a box, they go crazy. everyone has sex, so everyone seems to get a little bit.

but what’s never been shown in an experiment before is whether they EXCHANGE food for sex. so yeah, they have sex, but will they give food in exchange for it?
