"Evidence for representation of pretend objects by Kanzi, a language-trained bonobo

Classic childhood activities like tea parties and sword fights with sticks demonstrate the human ability to generate secondary representations, conditions we know aren’t 'real' but that we nonetheless engage with. Whether nonhuman animals are capable of these types of representations has been difficult to test. Bastos and Krupenye studied a language-trained bonobo, Kanzi, to see whether he could understand and engage with pretend conditions. Across three different experiments, Kanzi was able to identify pretend objects, demonstrating that he could create a secondary representation and showing that humans are not alone in this ability.

Secondary representations enable our minds to depart from the here-and-now and generate imaginary, hypothetical, or alternate possibilities that are decoupled from reality, supporting many of our richest cognitive capacities such as mental-state attribution, simulation of possible futures, and pretense. We present experimental evidence that a nonhuman primate can represent pretend objects. Kanzi, a lexigram-trained bonobo, correctly identified the location of pretend objects (e.g., ‘juice' poured between empty containers), in response to verbal prompts in scaffolded pretense interactions. Across three experiments, we conceptually replicated this finding and excluded key alternative explanations. Our findings suggest that the capacity to form secondary representations of pretend objects is within the cognitive potential of, at least, an enculturated ape and likely dates back 6 to 9 million years, to our common evolutionary ancestors."

"Despite their contrasting reputations, bonobos and chimpanzees show similar levels of aggression in zoos.

Chimpanzees have a reputation for being aggressive, while bonobos are often seen as their peaceful counterparts. This contrast has frequently been used to explain different sides of human nature. However, a new study by Utrecht University behavioural biologists Emile Bryon, Edwin van Leeuwen, Tom Roth and international colleagues shows that, in zoos, chimpanzees are not more aggressive than bonobos. The study was published today in the scientific journal *Science Advances*.

The team of researchers compared the occurrence of aggressive behaviours in 22 zoo-housed groups of chimpanzees and bonobos. While no difference was found in overall aggression, the team did find that the two sister species differ in how the aggression is distributed. Bryon: 'In chimpanzees, aggression mainly comes from males and is directed at everyone. In bonobos, aggression comes from everyone but is mostly directed at males.'”

This will be a brilliant paper on the evolution of cooperation between groups as exemplified by #bonobos and bottle nose #dolphins (they are not always nice, don't be kidded, selfish genes in action!)

Bonobos are just as aggressive as chimps, but there's a key difference — the female bonobos

A new study of chimpanzee and bonobo groups at zoos reveals similar levels of aggression. However, scientists found stark sex-based differences between the species.

Yup. #Chimpanzees not more aggressive than #bonobos

"aggression patterns diverge by sex: Bonobos exhibit higher female-to-male aggression, while chimpanzees show the reverse."

Rhythm during sex in bonobos provides new insights into the evolution of communication

An international research team, including VUB data scientist Yannick Jadoul, has shed new light on the rhythmic nature of sexual behavior in bonobos. By precisely analyzing the tempo of movements during sex, researchers aim to better understand which building blocks of rhythm and communication are present in other species—and what this implies for the evolution of uniquely human traits such as speech and music.
