Answer 3

— Chimpanzees: (RITUALISTIC APPEASEMENT GESTURES)

• What?
  
  • Jane Goodall:
    
    • Filmed male chimpanzees in Tanzania
    • Group of chimpanzees systematically slaughtered another group of male chimpanzees
      
      • Pre-meditated + coordinated attacks
    • Attacks lasted 20 minutes
    • Victims showing signals of appeasement + defencelessness
      
      • Attackers didn’t care
      • Signals did not inhibit aggressive behaviour
• So?
  
  • Evidence not all animals can instinctively stop aggressive behaviour
