|In recent years, genetic variation of human populations has been revealed at the genomic scale. There is also a growing recognition that environmental/ecological integrity and conservation of the complex web of life on Earth are crucial for sustaining human welfare. In light of these developments, it is necessary to understand humans as members of the global ecosystem by combining genetic and ecological knowledge within an evolutionary framework. By using (primarily) non-model organisms to explore genetic variation and its ecological correlates in wild populations, it is now possible to reevaluate the evolutionary significance of human genetic variation. The number of species whose genome has been sequenced is rapidly increasing, and this rich data set enables the assessment of functional differences between genetic variants. The evolutionary diversity of sensory systems—the visual system in particular—is an excellent model case for addressing these questions because recent technical developments have enabled functional evaluation of the relevant genes. Bearing these issues in mind, we pursue research projects on sensory genetics, ecology, and evolution using an interdisciplinary approach that spans molecular biology (population DNA sequencing, gene expression analysis, in vitro functional assays), biochemistry, population/evolutionary genetics, and behavioral ecology.
