Bonobos Take Make-Believe to a Whole New Level, Study Suggests
In a groundbreaking study, researchers have discovered that bonobos are capable of playing make-believe just like children. The findings, published in the journal Science, reveal that these intelligent primates were able to identify and interact with imaginary objects in pretend scenarios.
The study centered around Kanzi, a bonobo who had been trained to communicate with humans through a unique rearing process. Dr. Amalia Bastos and her team from the University of St Andrews conducted a series of experiments designed to test Kanzi's understanding of pretend play.
In one experiment, Kanzi was presented with two transparent cups and pretended to be filled with juice. The researchers then asked him to identify which cup contained the liquid. To their surprise, Kanzi correctly identified the "full" cup in 34 out of 50 trials, suggesting he had a deep understanding of the concept of pretend liquids.
But what's more remarkable is that Kanzi was not rewarded for his correct answer. This meant that he wasn't simply following human cues or learning to respond to certain behaviors. Instead, he demonstrated a genuine comprehension of the imaginary scenario.
The researchers also tested Kanzi's ability to distinguish between tangible and imaginary objects. In one experiment, they presented him with two cups containing real juice and an empty cup. When they pretended to fill the empty cup with an empty jug, Kanzi chose the cup with the actual liquid in 14 out of 18 trials.
These findings have significant implications for our understanding of human evolution and cognitive development. The researchers believe that the ability to make-believe is a fundamental aspect of human culture and may date back to our common ancestor with bonobos, which lived around 6-9 million years ago.
The study's lead author, Dr. Bastos, notes that this discovery challenges our assumption that making-believe is unique to humans. "As such, our findings suggest that the capacity for representing pretend objects is not uniquely human," she writes.
While further research is needed to confirm these results in apes without Kanzi's specialized training, the study provides a compelling case for the cognitive abilities of bonobos and challenges us to rethink what it means to be human.
