Baby chimps develop regional accents, new study finds
Researchers recorded more than 11,000 calls from 30 young chimpanzees and found site-specific vocal patterns that sharpened as the animals aged.
- Published on September 2, a study in PLOS One reveals young chimpanzees develop population-specific vocal accents, challenging the assumption that these calls are entirely genetically programmed.
- Researchers analyzed 11,225 recorded calls from 30 chimpanzees at Chimfunshi Wildlife Orphanage in Zambia and Gombe National Park in Tanzania to track how vocalizations evolve across populations.
- While grunts and laughs displayed population-specific signatures early in infancy, whimpers only developed distinct regional variations during juvenile years, suggesting vocal traits are shaped by social environments.
- Lead researcher Kassandra Giragosian of Queen Mary University of London said vocalizations "continue to develop" beyond birth, mirroring how human vocal patterns sharpen as children absorb nearby speech.
- Evidence suggests chimpanzee communication is more flexible than previously believed, with vocalizations reflecting not genetic presets but an audible history of social integration and community membership.
