| Outline of Final Research Achievements |
By analyzing the nature of the game derived from the dynamic decision making theory, we clarified that it differs from the result of the conventional game. We also found that the best choice changes dynamically depending on the player's wealth. In particular, we found that people with lower wealth (poor) are more likely to choose cooperative action. Furthermore, we have mathematically proved that the universal cheating on female birds can be explained by the risk spreading to avoid infertile males. Furthermore, it was clarified that the variability of the environment promotes the coexistence of many species in various communities. As mentioned above, it is clarified that the conventional adaptation concept needs a big change in consideration of environmental uncertainty.
