Outline of Final Research Achievements

We developed a novel method of molecular phylogenetic analysis that enables us to employ comprehensive data of DNA sequences of various genes in the skeleton framework of whole genome sequences, and applied it to the family Drosophilidae as a model group of organisms. The inferred phylogeny was highly resolved, corroborating the efficiency of the novel methodology. Especially, as to the largest genus Drosophila of which phylogeny has not fully been resolved, several important new findings have been brought, which will lead to fundamental changes in the framework of taxonomic and evolutionary studies on the Drosophilidae.
