What's happened
A new study reveals that chimpanzees drum on tree roots with distinct rhythms, suggesting that rhythmic abilities may date back to our common ancestor. The research, published in Current Biology, highlights the role of rhythm in chimpanzee communication and its evolutionary significance.

Key Findings
- Rhythmic Patterns: The study analyzed 371 drumming bouts from 47 chimpanzees across six populations, revealing non-random timing in their drumming.
- Subspecies Differences: Western chimpanzees prefer evenly spaced beats, while eastern chimpanzees use varied intervals, suggesting societal influences on their communication styles.
- Evolutionary Implications: These findings imply that the building blocks of rhythm existed in our last common ancestor, pushing back the origins of musicality in human evolution.
Implications for Understanding Communication
- Long-Distance Communication: The drumming serves as a method for chimps to communicate over long distances, potentially alerting others to their location.
- Social Interaction: Each chimp's unique drumming style acts as an individual signature, enhancing social bonds and interactions within groups.
Future Research Directions
- Ecological Factors: Further studies could explore how environmental factors influence drumming styles and communication among different chimp populations.
- Comparative Studies: Investigating other primates may provide additional insights into the evolution of rhythm and communication in social species.
What the papers say
According to The Guardian, researchers found that chimpanzees drum with non-random timing, indicating a rhythmic ability that may date back to our common ancestor. Prof. Catherine Hobaiter stated, "[The findings] are a strong suggester that those building blocks [of rhythm]... were present way back in our last common ancestor." The Independent also highlighted that chimps use specific tree roots to create sounds that travel well through dense jungle, emphasizing the importance of their drumming in social interactions. The AP News noted that the study's findings could reshape our understanding of the evolutionary origins of music, suggesting that rhythm is a fundamental aspect of social behavior.
How we got here
Chimpanzees and humans share a common ancestor from around six million years ago. Previous studies indicated that chimps have unique drumming styles, but the rhythmic nature of their drumming was not fully understood until now.
