  • Although the Suidae animals were one of the most prosperous mammals, their taxa and phylogeny were poorly studied. To bridge this research gap, the complete mitochondrial DNA cyt b sequences (1 140 bp)of one red river pig (Potamochoerus porcus), one bearded pig (Sus barbatus), and several Eurasian wild boars (Sus scorfa) were determined with direct PCR sequencing method. Incorporated with the sequences of other Suidae species obtained from GenBank, the phylogentic trees of Suidae species were constructed by Neighbor-Joining and Most Parsimony method. Our results showed that the babirousa was sister group of all other species. The African species clustered into a single clade, while the Eurasian species formed the other clade. The phylogenetic positions of the Sus species were consistent with their geographical distribution. Based on our phylogeographical results, the Sus species could be classified into three groups: (1) the relatively primitive animals from Philippine Islands (such as S. cebifrons and S. philippensis), Sulawesi and it's adjacent islands (S. celebensis), (2) the Eurasian wild boars (S. scrofa and the mysterious S. salvanius), and (3) other pigs (such as S. barbatus and S. verrucosus), which might further diverged as the islands type (such as S. barbatus from Sumatra and Borneo) and the continental type (such as Malay Peninsula wild boar).
