Researchers Have Successfully Taught Bonobos to Engage in Make-Believe Play
A groundbreaking study published in the journal Science has shed new light on the complex cognitive abilities of bonobos, one of our closest living relatives. Led by Dr. Amalia Bastos from the University of St Andrews, the research team successfully trained a bonobo named Kanzi to engage in make-believe play, mirroring the creative imagination and problem-solving skills of human children.
The study built upon previous work with Kanzi, who was raised using a sophisticated communication system that allowed him to understand and express complex concepts. The researchers took this foundation a step further by presenting Kanzi with imaginary objects, such as pretend cups filled with juice, and asking him to identify which container held the liquid.
To their surprise, Kanzi consistently chose the correct cup, demonstrating an understanding of the concept of pretence and the ability to distinguish between tangible and imaginary objects. This impressive feat was not solely based on observation or imitation, but rather on his own cognitive processing of the scenario.
The researchers also conducted additional experiments to test Kanzi's ability to follow imaginary objects in pretend scenarios. In one experiment, he was presented with two transparent containers containing a grape, and asked to identify which container held the fruit. With remarkable accuracy, Kanzi chose the correct container every time.
These findings not only provide new insights into the cognitive abilities of bonobos but also raise questions about our shared evolutionary past. According to Dr. Bastos, "the ability to make-believe could reach deep into our evolutionary past," suggesting that this capacity may have been present in our common ancestor with bonobos around 6-9 million years ago.
While the study's results are exciting, they also underscore the complexity and diversity of cognitive abilities across species. Prof. Zanna Clay from Durham University noted that it is not surprising to find imaginative thinking in closely related species like bonobos, given their advanced cognitive abilities and social complexity. "It would be more astonishing if we found this ability in more distantly related species with more divergent social and cognitive abilities," she observed.
The study's implications for our understanding of the evolution of human cognition are significant, and further research is warranted to explore the neural mechanisms underlying imaginative thinking in both humans and non-human animals.
