| Outline of Final Research Achievements |
The project, named "Elucidation of molecular mechanism of macroevolution" can b e divided into two parts. One is about the contribution of transposable elements which were inserted into genomes on macroevolution. We elucidated the enhancer of Wint5a responsible for making the secondary palate can be divided into three parts, each of which was inserted into the genome at the different time of evolution and played a different role in its function.
The second is about what the fighting is. The fighting is the important and conserved behavior of animals because a population led by a strong boss can survive more easily. Using a fighting fish pair, we elucidated that the transcripts of two individuals of a fighting pair are synchronized. This is a very interesting and new discovery.
