获得了所有公认的属的新世界猴（灵长类：Platyrrhini）和外类群的6个核基因的正向序列，以评估系统发育关系，并估计分歧时间。系统发育关系重建的最大简约法，最大似然法，贝叶斯方法。所有的方法解决了100%的分支支持属级关系，除了分组的Aotus作为一个姐妹类群的Cebus和Saimiri，这是支持低自举百分比和后验概率。所有的方法都描绘了三个单系的新世界猴家族：Atelidae，Cebidae和Pitheciidae;在每个家族中，所有的方法都描绘了相同的分支拓扑结构。然而，在描述三个家庭之间的关系时，方法各不相同。最大简约描述Atelidae和Cebidae姐妹家庭其次加入Pitheciidae。相反，可能性和贝叶斯系统发育树组家庭Atelidae和Pitheciidae一起排除Cebidae。分歧时间估计使用本地分子钟和贝叶斯方法表明，家庭分歧从另一个在很短的地质时间在晚渐新世早中新世。(c)2005年爱思唯尔公司All rights reserved.
Orthologous sequences of six nuclear genes were obtained for all recognized genera of New World monkeys (Primates: Platyrrhini) and outgroups to evaluate the phylogenetic relationships and to estimate divergence times. Phylogenetic relationships were reconstructed by maximum parsimony, maximum likelihood, and Bayesian approaches. All methods resolved with 100% branch support genus-level relationships, except for the grouping of Aotus as a sister taxa of Cebus and Saimiri, which was supported by low bootstrap percentages and posterior probability. All approaches depict three monophyletic New World monkey families: Atelidae, Cebidae, and Pitheciidae; also within each family, all approaches depict the same branching topology. However, the approaches differ in depicting the relationships of the three families to one another. Maximum parsimony depicts the Atelidae and Cebidae as sister families next joined by the Pitheciidae. Conversely, likelihood and Bayesian phylogenetic trees group families Atelidae and Pitheciidae together to the exclusion of Cebidae. Divergence time estimations using both local molecular clock and Bayesian approaches suggest the families diverged from one another over a short period of geological time in the late Oligocene-early Miocene.
