Kanzi, a bonobo raised in a lab, is challenging what we know about imagination in animals. By age two, most children dive into imaginative play, creating worlds and scenarios that aren’t real. This creativity is often seen as distinctly human. But recent studies suggest that Kanzi might possess similar abilities.
Kanzi is skilled at using graphic symbols to communicate. He has even learned to make simple tools. Researchers grew curious about whether he could play pretend—acting as if something is real, even when it isn’t. In the wild, there have been reports of chimpanzees engaging in imaginative play, like pretending sticks are babies. However, proving true imagination in apes is tricky because it’s hard to know what they’re really thinking.
In a study, researchers set up a pretend juice party for Kanzi. They poured imaginary juice and then asked which cup he wanted. Remarkably, he picked the cup with pretend juice 68% of the time. When tested with real juice, he chose it almost 80% of the time. This suggests he understands the difference between the real and the imagined.
A third experiment involved fake grapes placed in jars, which also showed positive results. But not all experts agree with these interpretations. Michael Tomasello, a comparative psychologist, argues that just because Kanzi can point to pretend juice doesn’t mean he understands the concept the same way humans do. He believes true pretending involves actively creating scenarios, like pouring imaginary juice himself.
Kanzi’s unique upbringing among humans could be a factor in his abilities. He passed away last year at 44, leaving researchers eager to explore what imagination really means for great apes. They stress the need for further studies, especially since many great ape species face extinction.
As zoologist Amalia Bastos noted, “Kanzi opened this path for a lot of future studies.” Understanding animal creativity could change how we view not just apes but the entire animal kingdom.
In our rapidly changing world, as recent statistics show, 60% of people now believe animals have emotional and cognitive capabilities comparable to humans. The conversation around animal intelligence is evolving, and studies like Kanzi’s play a vital role in shaping our understanding.
