What to know about Chimpanzees reveal 69 socially learned behaviors, nearly doubling known cultural repertoire

Researchers from the Max Planck Institute of Animal Behavior observed wild chimpanzees in Uganda to identify socially learned behaviors. The study suggests that chimpanzee culture is broader than previously thought, encompassing everyday survival skills in addition to complex tool use.

What happened

Chimpanzees reveal 69 socially learned behaviors, nearly doubling known cultural repertoire Gaby Clark Scientific Editor Robert Egan Associate Editor Scientists have identified dozens of previously overlooked cultural behaviors in wild chimpanzees, suggesting…

Why it matters

In a single community, they found nearly 70 behaviors that chimpanzees appear to learn from one another—almost doubling previous estimates of cultural behaviors across African chimpanzee populations.

Common ground

Rethinking what counts as culture Researchers spent several years observing wild chimpanzees in the Ugandan rainforest to document the range of skills that chimpanzees learn by observing others.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
