• Why is baring teeth considered adaptive in animals?

  It reduces death in conflicts, promoting survival

• Why does the evolutionary theory not fully explain non-verbal communication (NVC)?

  Cultural differences in NVC exist, like personal space
• What are the key points of the evolutionary theory of non-verbal behavior?

  • Natural selection promotes survival behaviors
  • NVC evolved to express emotions
  • Behaviors like baring teeth reduce conflict
  • Adaptive behaviors passed down through generations
  • Cultural differences limit the theory's applicability
