| Research Abstract |
To assess possible correlations between Gondowana braking-up and anuran divergence, mitochondrial (mt) genomes and nuclear genes were analyzed. The main results are the followings. 1) PCR primers that can amplify the whole mt genome of wide frog taxa were designed. 2) It was suggested that the amino acid data of mt genes should be used in divergence analyses for frog taxa. 3) An Asian microhylid shows close relationship with the Australian group, suggesting that the branching pattern of this taxon could not match the continent vicariance process.
