Our interpretation of the results from parsimony, distance and maximum likelihood based phylogenetic analyses suggest:(1) African colobines and Asian colobines have been independent evolutionary entities for a long time; the divergent time is estimated to occur 10 million years ago based on a molecular clock of 2% substitution per site per million years;(2) both Rhinopithecus and Trachypithecus could be regarded as separate genus;(3) Pygathrix and Rhinopithecus are sister groups while Presbytis and Trachypithecus are closely related;(4) both the Sichuan and Yunnan snub-nosed monkey represent valid species respectively;(5) within genus Trachypithecus, T. phayrei is closely related to T. cristatus and T. auratus, while T. francoisi is distinct from them; the white-headed leaf monkey, however, should be a subspecies of T. francoisi;(6) within genus Presbytis, P. thomasi should be separated as a valid species from P. melalophos, but the genetically divergent degree between P. comata and P. melalophos implies that P. comata may just be a subspecies of P. melalophos.
结果表明:(1)非洲疣猴与亚洲疣猴的分歧已非常明显,按分子钟推算的分歧时间约在1,000万年前;(2)Rhinopithecus和Trachypithecus均应成为独立的属;(3)白臀叶猴属与金丝猴属关系较近,Presbytis属和Trachypithecus属关系也较近;(4)我国的川、滇金丝猴应分别被视为独立的物种;(5)在Trachypithecus属中,菲氏叶猴与银叶猴(T.cristatus)和乌木叶猴亲缘关系较近,黑叶猴(T.francoisi)则与它们的关系较远,曾被怀疑为一个种的白头叶猴(T.f.leucocephalus)应只是黑叶猴的一个亚种;(6)在Presbytis属内,托氏叶猴应从僧帽叶猴(P.melalophos)中独立出来成为一个有效种,但我们的结果倾向于将灰发叶猴置为僧帽叶猴的一个亚种。

Biologists broke the original population down into eight subspecies, based on looks and geography, from the relatively small and dark Indochinese tiger of southern continental Asia to the massive Siberian tiger of the Russian far east. In 2004, researchers for the first time applied DNA analysis to the tiger family tree and confirmed the existence of five extant subspecies.
