For the elucidation of the phylogenetic position of insectivora in eutheria, we have sequenced the cytochrome c oxidase subunit II(COII)gene of mitochondria for three insectivoran species [musk shrew(Suncus murinus), shrew mole (Urotrichus talpoides), Japanese mole(Mogera wogura)] and analyzed these amino acid sequences with neighbor-joining(NJ)method and maximum likelihood(ML)method. NJ analysis shows polyphyly of Insectivora and Chiroptera. Assuming that each of Primates, Ferungulata, Chiroptera, Insectivora and Rodentia is a monophyletic group, ML analysis suggests that Chiroptera is a sister group of Insectivora and that Ferungulata is the closest outgroup to the(Insectivora and Chiroptera)clade.
