The phylogenetic analyses investigated using Maximum likelihood (ML) and Bayesian inferences (BI) analysis indicated evolutionary relationships among 46 mitochondrial genome sequences based on the tandem nucleotide alignments of 13 protein-coding genes. The tree topologies produced by ML and BI analyses were equivalent. Bayesian posterior probability with 2×108 generations and bootstrap support values for ML analyses with 1000 replicates are shown on the nodes. Giraffa camelopardalis (AP003424), Okapia johnstoni (JN632674) and Antilocapra americana (NC_020679) were selected as an outgroup. Several classification suggestions are shown in blue at the right of the taxa.
