| Outline of Final Research Achievements |
This project aims at understanding coevolution of learning and niche construction in sympatric species using complex systems approaches. First, we constructed a minimal model where several different species participate in a partitioning of their shared niches, and evolve their behavioral plasticity to avoid an overlap of their niche use. We found that the two different types of asymmetric distributions of phenotypic plasticity emerge depending on the settings of the degree of congestion of the shared niches. Then, we constructed and analyzed computational and coevolutionary models of language-language ability, plant-insect, predator-prey interactions, etc. We also conducted related computational experiments on evolution of learning or niche construction, considered engineering applications of the findings assuming the information transmission in wireless sensor networks, and considered relationships between the findings and singing behaviors of birds.
