Chimpanzees show signs of intergenerational collective intelligence, similar to humans.
Chimps Exhibit Complex Tool Use, Passing Down Skills
NEW YORK — While instances of cooperation in chick-rearing involve only two generations, a new understanding of collective intelligence is emerging from the animal kingdom. This intelligence, previously observed in limited bird species, now appears to manifest in our closest primate relatives, chimpanzees.
A study published this fall in Science highlights a fascinating link between advanced tool use and social mobility in certain chimpanzee populations. These chimpanzees demonstrate a sophisticated form of intergenerational collective intelligence, a concept that enriches our understanding of social learning across species.
- Certain chimpanzee populations exhibit intergenerational collective intelligence.
- This intelligence is linked to complex tool use and social mobility.
- Adult females migrating between groups transmit and adapt know-how.
- This process leads to an accumulation and complexification of knowledge over generations.
What is intergenerational collective intelligence in chimpanzees? It’s the transmission and evolution of tool-use knowledge across multiple generations.
In these specific chimpanzee groups, adult females often leave their birth group to join new ones. As they integrate, they impart their acquired skills and knowledge to the next generation. This learned behavior isn’t static; the chimpanzees adapt these techniques to their specific environment, introducing variations and improvements.
Over time, this continuous process of learning, adaptation, and transmission results in increasingly complex tool-use strategies. It’s a clear indication of collective intelligence, built through the accumulated wisdom of successive generations.
When compared to birds known for cooperative breeding, chimpanzees show two key differences. Firstly, the learning process is direct, from one individual to another, such as a mother teaching a young chimpanzee. Secondly, there’s a tangible accumulation and refinement of knowledge, a characteristic absent in the bird examples.
Despite these distinctions, the core element of collaboration across generations remains evident in both species.

Humanity, too, has followed an evolutionary path that embraces these modes of collaboration. This has allowed our species to diversify the ways we express collective intelligence, and this journey of discovery is likely just beginning.
