Outline of Final Research Achievements

The theory of natural selection and the neutral theory of molecular evolution are powerful concepts in evolutionary biology. However, even with such theories, there still remain　unexplained phenomena, one of which is the evolution of complexity. We studied (1) evolution of Sarracenia purpurea pitcher leaves, (2) Genome sequence of Cephalotus follicularis and evolution of digestive enzymes, (3) Convergent evolution of digestive enzymes with adaptation to fluid environment, and so on.
