Phylogenetic tree of Rhinocerotidae based on mitochondrial sequences and habitus of Southeast Asian rhinoceroses. A: Bayesian 50% majority consensus tree based on 12S rDNA sequences. Posterior probabilities from Bayesian inference (left) and bootstrap support values (≥ 50%) from the maximum likelihood (middle) and maximum parsimony (right) analyses are indicated at the nodes. B, C: chromolithographies of the Sumatran rhinoceros (Dicerorhinus sumatrensis; B) and the Javan rhinoceros (Rhinoceros sondaicus; C), modified from Sclater (1876).
