| Outline of Final Research Achievements |
We studied moment-expansion method and meta-population fitness method as models to research the evolutionary origin of biodiversity. We found that the two methods yield exactly the same analytic result. We also found that, under natural selection produced by any two-player games, deme structure always inhibit evolutionary branching. These results suggest that, if homogenous environment is divided into deme structures, the emergence of biodiversity is not enhanced by disruptive natural selection, compared to the case of non-divided populations.
