The results of previous systematic studies of Old World monkeys using morphological and molecular techniques have been in disagreement. Many possible relationships have been proposed for members of the tribe Papionini (baboons, drills, mandrills, macaques and mangabeys), but no previous studies have been based on nucleotide sequences. The question of these relationships will be addressed using cytochrome c oxidase (COII) mitochondrial gene nucleotide sequences to derive phylogeneic hypotheses. This gene is ideal for a study of Papionini systematics due to its rate of change, lack of recombination, and ease of study. The results of this study should provide two kinds of valuable information. First, a better understanding of the phyletic relationships among Old World monkeys should be possible. Second, by comparing Papionini gene sequences to those of other primates and non-primate mammals, a better understanding will emerge of the rate of change in the mitochondrial genome. This is important since the rate affects conclusions regarding the order and timing of branching events, and consequently interpretations of the fossil record both for these primates and for other primate lineages.

以前对旧大陆的系统研究的结果 利用形态学和分子技术， 分歧 已经提出了许多可能的关系， Papionini部落的成员（狒狒，钻头，山鸡， 猕猴和白眉猴），但以前的研究没有基于 关于核苷酸序列。 这些关系的问题 将使用细胞色素c氧化酶（COII）线粒体 基因核苷酸序列，以得出同源假说。 这 基因是理想的研究Papionini系统学，由于其 变化率，缺乏重组，易于研究。 这项研究的结果应该提供两种 有价值的信息 第一，更好地了解 旧大陆猴子之间的亲缘关系应该是 可能 第二，通过比较Papionini基因序列和那些 其他灵长类动物和非灵长类哺乳动物， 线粒体基因组的变化率。 这一点很重要，因为利率会影响以下结论： 分支事件的顺序和时间， 对这些灵长类动物化石记录的解释， 其他灵长类的血统。
