The phylogenetic relationships among the genera of the tribe Papionini are inferred using a taxonomic congruence approach in which gene trees derived for eight unlinked genetic sequence datasets are compared. Population genetics theory predicts that species relationships will be revealed with greater probability when the topology of gene trees from many unlinked loci are found to be congruent. The theory underlying this approach is described. Monophyly of the mangabeys is not supported by any of the gene trees; instead, they are polyphyletic with Cercocebus found to be the sister taxon to Mandrillus in five gene trees (with no conflicting trees), and Lophocebus found to be closely related to Papio and/or Theropithecus in all trees. Theropithecus and Papio are not strongly supported as sister taxa (present in one or two trees only);Lophocebus and Papio are supported as sister taxa in the majority of trees. A close relationship between Mandrillus and Papio is not supported in any of the trees.The relationships among Papio, Lophocebus, and Theropithecus cannot be resolved by congruence, probably due to the short time interval estimated between their divergences. The mtDNA COII sequences are used to estimate divergence dates within the papionins. The internode between the divergences of these species is estimated to be between 290 ka and 370 ka. Lastly, the evolution of morphological features such as long faces, suborbital facial fossae, and terrestrial skeletal adaptations is discussed.
使用分类学一致性方法推断狒狒族各属之间的系统发育关系，该方法比较了从八个不连锁的遗传序列数据集得出的基因树。群体遗传学理论预测，当发现来自许多不连锁基因座的基因树拓扑结构一致时，物种关系将更有可能被揭示。描述了该方法的基础理论。没有任何一个基因树支持白眉猴的单系性；相反，它们是多系的，在五棵基因树中（没有冲突的树），长尾猴被发现是山魈的姐妹分类单元，并且在所有树中，疣猴被发现与狒狒和/或狮尾狒密切相关。狮尾狒和狒狒作为姐妹分类单元的支持力度不强（仅出现在一两棵树中）；在大多数树中，疣猴和狒狒被支持为姐妹分类单元。在任何一棵树中都不支持山魈和狒狒之间的密切关系。狒狒、疣猴和狮尾狒之间的关系无法通过一致性来解决，可能是由于估计它们分歧之间的时间间隔较短。线粒体DNA COII序列用于估计狒狒科动物内部的分歧日期。这些物种分歧之间的节间估计在290 ka到370 ka之间。最后，讨论了诸如长脸、眶下面部窝和陆地骨骼适应等形态特征的进化。
