为了了解亚洲叶猴多样性的进化过程，本文报道了三种近缘叶猴的系统发育、地理分布和种群遗传学分析。poliocephalus和T. leucocephalus，这是所有的特点是不同的毛皮着色主要是在头部和肩部。因此，我们从178个T. francoisi，54 T. leucocephalus和19株T. poliocephalus个体，代表这三个物种的所有现存种群。在T. francoisi，T. leucocephalus和T.脑灰质炎T. leucocephalus和T. poliocephalus形成单系分支，它们都嵌套在T. francoisi，与T. francoisi最近，0.46-0.27（T. leucocephalus）和50 - 25万年前（T.脊髓灰质炎）。因此，T. francoisi似乎是一个多系群，而T. leucocephalus和T. poliocephalus很可能是T. francoisi，两者都与T. Francoisi种群由河流，公海或较大的栖息地间隙。自从T. francoisi种群的毛色无变异性，T. leucocephalus和T.脊髓灰质炎很可能是从T. francoisi，而不是固定的不同字符来自祖先的多态性。该案例研究强调了在相对较短的时间内，在孤立的种群中可以发生形态学变化，例如毛皮颜色，它为相关物种的研究提供了坚实的基础。然而，为了充分了解这三种叶猴的进化历史，核基因座也应该进行调查。
To understand the evolutionary processes leading to the diversity of Asian colobines, we report here on a phylogenetic, phylogeographical and population genetic analysis of three closely related langurs, Trachypithecus francoisi, T. poliocephalus and T. leucocephalus, which are all characterized by different pelage coloration predominantly on the head and shoulders. Therefore, we sequenced a 395 bp long fragment of the mitochondrial control region from 178 T. francoisi, 54 T. leucocephalus and 19 T. poliocephalus individuals, representing all extant populations of these three species. We found 29 haplotypes in T. francoisi, 12 haplotypes in T. leucocephalus and three haplotypes in T. poliocephalus. T. leucocephalus and T. poliocephalus form monophyletic clades, which are both nested within T. francoisi, and diverged from T. francoisi recently, 0.46-0.27 (T. leucocephalus) and 0.50-0.25 million years ago (T. poliocephalus). Thus, T. francoisi appears as a polyphyletic group, while T. leucocephalus and T. poliocephalus are most likely independent descendents of T. francoisi that are both physically separated from T. francoisi populations by rivers, open sea or larger habitat gaps. Since T. francoisi populations show no variability in pelage coloration, pelage coloration in T. leucocephalus and T. poliocephalus is most likely the result of new genetic mutations after the split from T. francoisi and not of the fixation of different characters derived from an ancestral polymorphism. This case study highlights that morphological changes for example in pelage coloration can occur in isolated populations in relatively short time periods and it provides a solid basis for studies in related species. Nevertheless, to fully understand the evolutionary history of these three langur species, nuclear loci should be investigated as well.
