Flashcards
Chimpanzee Military Tactics
Chimpanzee Military Tactics
Chimpanzees, like humans, use elevated positions to assess the risk and potential outcome of conflict with other groups. They strategically chose high ground to survey their surroundings and make informed decisions.
Chimpanzee Territory Patrols
Chimpanzee Territory Patrols
Chimpanzees regularly patrol the edges of their territories, actively demonstrating their presence and asserting dominance. This behavior is similar to how human armies patrol their borders.
Dynamic Chimpanzee Borders
Dynamic Chimpanzee Borders
The location of a border between chimpanzee communities constantly shifts based on daily activity and perceived risk. The group that is more active in an area, especially on higher ground, has a stronger claim to that territory.

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.
