Introduction of Research

In this lab, our going research is to clarify the history on formation of the mammalian fauna and their divsersity on the Japanese islands. There are many questions on the Zoogeographical questions: for example, how the Japan-endemic mammals including the Japanese weasel and Japanese badger etc. have been speciated, why the brown bear lives on Hokkaido but the Asiatic black bear is distributed on Honshu. For clarifying the questions, the methodologies of molecular phylogeny and population genetics have been invoived. In addition, because it is true that the evolutionary origins of the Japanese mammlas are in the Euarasian continent, it is important to have international collaborations with researchers of the continent.
