Understanding Great Ape Intelligence and Culture

Recent studies have revealed significant insights into the cognitive abilities and cultural behaviors of great apes, challenging long-held beliefs about human uniqueness. A notable experiment conducted at the Ape Initiative facility in Des Moines, Iowa, involved Kanzi, a bonobo, who participated in the first empirical test of pretend play in a great ape species. The findings, published in February 2026 in the journal *Science*, demonstrated Kanzi's ability to engage in imaginative play, suggesting that apes can grasp concepts beyond their immediate reality. This research is part of a broader trend that has uncovered remarkable similarities between ape and human behaviors.

In the 1990s, scientists began to recognize the intelligence of apes, noting their ability to solve puzzles, use tools, and exhibit self-awareness through the mirror test. However, the exploration of more complex cognitive traits, such as culture and theory of mind, has gained momentum only in recent decades. Researchers like Christopher Krupenye from Johns Hopkins University emphasize that chimpanzees and bonobos possess a keen sensitivity to their social partners, indicating a sophisticated understanding of others' thoughts and intentions.

Research has shown that great apes exhibit cultural diversity, with distinct behaviors and communication methods varying between groups. For instance, chimpanzees in different communities may use different tools or signals for similar actions. This cultural variation raises important questions about conservation strategies, as highlighted by Kristin Andrews, a professor at the City University of New York. She argues that preserving cultural diversity among chimpanzees should be a priority alongside biodiversity, suggesting the establishment of "cultural heritage sites" for protection.

The conservation status of great apes is precarious, with species such as the Bornean orangutan, Sumatran orangutan, Tapanuli orangutan, eastern gorilla, western gorilla, chimpanzee, and bonobo all classified as endangered or critically endangered. The loss of specific groups could result in the extinction of unique cultural practices, as Andrews points out. She warns that even if a species is saved, the erasure of cultural knowledge could lead to a loss of identity for the species.

Amalia Bastos, the lead author of the study on Kanzi, stated, “It seems to be a recurring thing in our field where people come up with reasons why humans are special and unique... maybe we’re not that special after all.” This sentiment reflects a growing consensus among researchers that great apes share cognitive traits previously thought to be exclusive to humans.

• “That animals, too, are capable of secondary representations or imagination.” — Amalia Bastos, Comparative Psychologist

• “This is a case where 30 years ago the dominant view was there is no evidence whatsoever.” — Christopher Krupenye, Cognitive Scientist

• “If we preserve chimpanzee DNA somewhere, but that organism that gets created from that DNA doesn’t know anything about being a chimpanzee, that’s not a chimpanzee. That’s something else,” — Kristin Andrews, Professor of Philosophy

The evolving understanding of great ape intelligence and culture not only reshapes our perception of these species but also underscores the urgent need for conservation efforts that consider both biodiversity and cultural diversity. As researchers continue to explore the cognitive worlds of great apes, the implications for conservation strategies and our understanding of what it means to be human become increasingly profound.
