"This study revealed genetic and non-genetic changes in biological rhythms while adapting to tidal environments in a freshwater snail. This result could lead to an understanding of the role of biological clocks in the adaptation to rhythmic environment, which is one of the most important issues in chronobiology," says Dr. Takahashi.
