📅This fact may be outdated
Kanzi did learn to build campfires and cook his own food, which was factually accurate. However, Kanzi passed away on March 18, 2025, at age 44. Since the fact uses present tense ('has learned'), it implies Kanzi is still alive and performing these activities, making it outdated.
There’s a bonobo named Kanzi who has learned to build a campfire and cook his own food.
Kanzi: The Bonobo Who Mastered Fire and Cooking
For decades, one bonobo captivated scientists and animal lovers worldwide with an ability that seemed almost impossibly human: Kanzi could build a fire from scratch and cook his own meals. Born in 1980, Kanzi spent most of his life at research facilities studying ape cognition, where he demonstrated skills that challenged our understanding of the gap between humans and our closest relatives. Sadly, Kanzi passed away on March 18, 2025, at age 44, marking the end of an extraordinary life.
Building Fires Like a Human
Kanzi didn't just poke at flames—he understood the entire process of fire-making. He would gather twigs and small branches, arrange them into a neat pile, strike a match (yes, an actual match), and carefully nurture the flame until it caught. Researchers believe his fascination began in his youth when he watched the film Quest for Fire, a movie about early humans discovering fire. Apparently, it left quite an impression.
Once the fire was going, Kanzi would roast marshmallows on a stick with surprising finesse, turning them carefully to achieve that perfect golden-brown char. He also cooked hamburgers in a pan over the flames and even prepared omelets. Dr. Sue Savage-Rumbaugh, who worked closely with Kanzi at the Ape Cognition and Conservation Initiative in Des Moines, Iowa, emphasized that Kanzi made fire because he wanted to—not because he was being rewarded, but because he genuinely enjoyed it.
More Than Just Fire
Fire-building was just one facet of Kanzi's remarkable cognitive abilities. He understood approximately 3,000 spoken English words and could communicate using a keyboard of lexigrams—symbols representing different words—pointing to around 500 of them to express himself. This made him one of the most linguistically sophisticated non-human animals ever studied.
Kanzi could also:
- Create primitive stone tools by striking rocks together
- Play Pac-Man and other simple video games
- Understand complex sentences and respond appropriately
- Follow multi-step instructions
His death in March 2025 from suspected heart failure came suddenly. That morning, he'd been foraging for breakfast, playing with his nephew Teco, and enjoying enrichment activities before settling in for a grooming session and becoming unresponsive. He was the last of the language-trained apes, making his passing the end of a significant chapter in primatology.
What Kanzi Taught Us
Kanzi's fire-making abilities weren't just a party trick. Fire use has long been considered a uniquely human milestone—a technology that separated us from other animals and enabled early humans to cook food, stay warm, and develop complex societies. Watching a bonobo master this skill raised profound questions about intelligence, learning, and what it truly means to be human.
Some scientists argued that Kanzi's abilities showed bonobos (and likely other great apes) have latent capacities that simply aren't expressed in the wild because they lack the cultural transmission and environmental pressures that drove human evolution. Others saw it as evidence that the cognitive gap between humans and apes is far narrower than we'd like to think.
Either way, Kanzi's legacy lives on. He showed the world that with the right environment, encouragement, and perhaps a good movie for inspiration, our closest relatives can achieve things we once thought impossible. Rest in peace, Kanzi—master of fire, lover of marshmallows, and pioneer of ape cognition.
