Phylogenetic analysis by Maximum Likelihood (a) and Bayesian (b) methods with the sequences obtained in this study and from GenBank on other Cetartiodactyla species. The percentages of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates for the ML tree and 200,000 iterations for the Bayesian tree) are shown next to the branches. The tree is drawn to scale with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree which are the number of base substitutions per site. For the ML method, the tree with the highest log likelihood (− 5444.4659) is shown
