The mitochondrial DNA (mtDNA) control region of two hundreds and thirty-six common pheasants (belonging to fourteen subspecies collected at twenty-eight localities) was used to investigate the subspecies status of Phasianus colchicus. Eighty-nine variable sites defined one hundred and thirty-nine haplotypes. Phylogenetic analysis of haplotypes revealed that P. c. shawii, P. c. mongolicus and P. c. suehschanensis were monophyletic. P. c. shawii and P. c. mongolicus were isolated by the Taklimakan, the Bardain, the Jaran and the Gurbantonggut Deserts where the two subspecies evolved independently. P. c. suehschanensis was isolated by the forest and mountains in the Sichuan Basin where it evolved independently. Further eleven subspecies were identified and split into the western and eastern groups. The divergence occurred in the late Pleistocene when the arid, semi-arid and monsoon regions formed, and it was induced by the isolation from the Qinling and Taihang Mountains. Fst-values decreased from 0.543 (for twenty-eight populations) to 0.541 (for fourteen subspecies). In light of these results, we suggest that the currently recognized subspecies do not reflect the evolutionary history of the common pheasant.
