Evolution can be viewed as series of changes introduced to developmental programs of organisms. The ultimate goal of our research project is to reconstruct the mechanical background of development behind evolutionary novelties in vertebrates, such as jaws and turtle crapace, by comparing developmental processes and patterns between different animal species to identify the changed portion of development, by constructing phenocopies to modify a part of developmental programs of model animals, and by integrating the experimental data with fossil data, phylogenetic trees based on molecular data, and variety of genomes in animals.
- To understand the developmental change that has brought about the gnathostome jaw, or origin of gnathostomes
- To understand the conprehensive developmental patterns and mechanisms of hagfish
- To understand the developmental changes brought into the body plan and its developmental program in the amniote ancestor to generate the turtle carapace
- To understand the mechanical background behind the basic patterning of the mandibular arch, including the developmental understanding of the evolution of mammalian ear ossicles.
- To understand the skeletal muscle evolution from the perspective of molecular developmental biology
