| Outline of Final Research Achievements |
The goal of this study was to demonstrate the commonality of ecological speciation. This study was divided into three parts: the first part is anolis. We showed the possibility of ecological speciation by measurements of light environments, the reflectance of dewlap, and absorption spectra of the LWS opsin pigments. 2) In notothenia part, we showed the visual adaptation of this fish to the environment of sea. 3) In cichlids part, we demonstrated that visual genes have evolved for adaptation to light environments and breeding coloration formation genes have evolved by sexual selection. These three studies represented the commonality of ecological speciation in vertebrates.
