Teamwork, pleasure and bargaining in animal social behaviour

Area of Science:

• Evolutionary Biology
• Animal Behavior
• Game Theory

Background:

• Animal intimate behaviors, such as grooming, dancing, and singing, are hypothesized to facilitate cooperative actions.
• The pleasure derived from synchronized activities is proposed as a motivator for coordinated efforts towards shared goals.
• Existing theories often view cooperation as altruism, but this hypothesis posits it as a mutual direct benefit.

Purpose of the Study:

• To explore the hypothesis that intimate animal behaviors enable teamwork through mutual direct benefits.
• To model the cooperative dynamics and resulting fitness enhancements using game theory.
• To clarify and correct previous confusions regarding the evolutionary basis of this cooperative behavior.

Main Methods:

• Theoretical modeling based on the concept of joint action in cooperative scenarios.
• Application of game theory, specifically the Nash bargaining solution, to analyze the equilibrium of returns in teamwork.
• Correction and re-evaluation of existing theoretical frameworks, referencing prior work (Binmore, 2010).

Main Results:

• Cooperative behavior in animals evolves as a mutual direct benefit, not altruism.
• Teamwork leads to an equilibrium of returns that is better modeled as a Nash bargaining solution than a Nash equilibrium.
• The dynamics of cooperation can be effectively modeled using joint action rather than individualistic action.

Conclusions:

• Intimate behaviors serve as a mechanism for evolving cooperation in animals, driven by direct fitness benefits.
• Game theory, particularly Nash bargaining, provides a suitable framework for understanding the outcomes of animal teamwork.
• The study refines the understanding of cooperative evolution by emphasizing joint action and mutual benefits.
