Approach of the Phylogenetic Position for Muschus Animals within Ruminantia in Terms of 12S rDNA Gene

Liu Xuedong, Zheng Dong, Ma Jianzhang(Northeast Forestry University, Harbin 150040, P. R. China)  
The complete 12S rRNA genes of Sika deer (Cervus nippon), Eldi deer(Cervus eldi), Siberian musk deer (Moschus moschiferus), Chinese forest musk deer (Moschus berezovskii) were sequenced (Accession No. AY184425, AY184428, AY184432, AY184433 ) and aligned with 12S rRNA gene sequences of Balabac chevrotain (Tragulus napu), giraffe (Giraffa camelopardalis), cow (Bos taurus) retrieved from GenBank. Given Balabac chevrotain as outgroup, phylogenetic trees were restructured respectively by ME, ML and MP methods. The results showed that Cervini, Bovini, Giraffini and musk deer respectively formed robust monophyletic group, and divergences between musk deer and each of clades including Bovini (11.9%~12.2%), Cervini (11.5%~12.4%) and Giraffini (13.3%~13.7%) stood within the range of divergence among superfamilies (11.6%~16.5%) (nonsignificant difference, P0.94). Musk deer became the sister group of Bovini (BCL:68%~86%) instead of Cervini. This article supported Hamilton (1978b), Webb and Taylor (1980) that musk deer be listed as an independent superfamily within Pecora.
