Study Notes
Chimpanzee Military Tactics
- Humans and chimpanzees share 98.8% of their DNA, leading to similar behaviors like communication (gestures, vocalizations) and tool use.
- New research suggests chimpanzees utilize human-like military tactics for assessing risk and expanding territory.
- Researchers (Dr. Sylvain Lemoine's team at the University of Cambridge) observed two western chimpanzee groups in Tai National Park, West Africa, from 2013 to 2016.
- GPS trackers monitored the chimps 8-12 hours daily per day.
- Chimpanzee groups routinely patrolled their territory boundaries, mimicking human military strategies.
- Groups moved closely in a coordinated manner, similar to human troop formations.
- To evaluate risks, chimps often positioned themselves on elevated ground along their borders.
- While observing from elevated positions, chimps listened for sounds from rival groups.
- The presence of chimpanzees in a territory determines the boundary, not a fixed line.
- Chimps' confidence to enter neighboring territories (and take them over) depends on the perceived risk of conflict—e.g., fewer rivals increase confidence.
- "Tactical warfare likely influences human evolution," says Dr. Lemoine, due to the observed cognitive abilities chimps employ to protect or expand territories.
- This behavior is unique to chimpanzees (besides humans). Other animals, unlike chimpanzees, do not use elevated ground to assess conflict risks.
- The study's findings were published in PLOS Biology on November 2, 2023.
- The study suggests similar tactics may be employed by other chimpanzee populations.
