Research Summary

Shigeru  Kuratani(Ph.D.)

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.
