Recent studies in 2025 have shed light on the complex communication methods of chimpanzees, revealing key elements that may provide insights into the evolution of human language. Researchers have identified rhythmic structures and call combinations in wild chimpanzees, suggesting that these primates possess communication skills more intricate than previously understood.
One study, featured in Current Biology, analyzed the drumming patterns of chimps in African rainforests. Chimpanzees drum on tree roots to communicate across distances, conveying messages about direction and social interactions. The study found that different chimp populations use distinct rhythmic structures, akin to regional accents, indicating learned and controlled communication attributes integral to human language.
Another study examined call combinations used by wild chimpanzees in Côte d'Ivoire. Researchers recorded over 4,000 utterances, discovering that combining calls can alter their meaning. For instance, a 'hoo' call might mean resting, while a 'pant' call indicates playing; however, the combination of 'hoo' and 'pant' often signifies nest building. These findings suggest that chimpanzees use call combinations to navigate their social environment, inquire about social dynamics, and possibly manage status changes within their groups.
