Exploring Organism Cooperation: Relatedness, Social Insects, and Evolutionary Strategies

Delve into the intricacies of why organisms cooperate, looking at relatedness, social insects, and cooperation evolution. Understand the Prisoners’ Dilemma and Chicken Game matrices, as well as optimal strategies for cooperation. Explore these concepts through theoretical frameworks and practical examples, such as Dictyostelium and spatial prisoners’ dilemma scenarios. Uncover the motivations behind cooperation and the impact of relatedness on evolutionary behaviors.

Presentation Transcript

  1. Why do organisms cooperate?

  2. Relatedness

  3. Dictyostelium http://www.uni-koeln.de/uni/aktuell_meld_amoebe.html

  4. Social insects http://www.sbs.utexas.edu/pupating/termite_model.htm

  5. Can cooperation evolve in the absence of relatedness?

  6. The basic PD matrix What I get from each possible outcome e.g. R = 0, S = -3, T = 2, P = -2 T > R > P > S

  7. Spatial prisoners’ dilemma http://prisonersdilemma.groenefee.nl/

  8. The super-rational strategy • an optimal strategy must be the same for both players • the result must lie on the diagonal of the payoff matrix • maximize return from solutions on the diagonal • cooperate

  9. The basic chicken matrix What I get from each possible outcome e.g. R = 0, S = -3, T = 2, P = -2 P < S, R < T
