A large body of diverse comparative data now exists for a major phylogenetic synthesis of the higher-level relationships among eutherian (placental) mammals. We present such a phylogenetic synthesis using the composite trees or supertrees from the combined and separate analyses of their published molecular and morphological source phylogenies. Our combined and separate supertrees largely support the same suprafamilial taxa and orders, but different interordinal clades. These similarities and differences reinforce the continuing contributions of morphological studies, while highlighting the growing influence of molecular information on the field. As current summaries of past research, our supertrees emphasize opportunities for future work, while providing a step toward the eventual integration of the data and characters themselves.
现在有大量多样的比较数据，可用于对真兽亚纲（有胎盘）哺乳动物之间更高级别的系统发育关系进行主要的系统发育综合分析。我们利用已发表的分子和形态学源系统发育的联合分析和单独分析得出的复合树或超级树，进行了这样的系统发育综合分析。我们的联合超级树和单独超级树在很大程度上支持相同等级以上的分类单元和目，但目间分支不同。这些异同强化了形态学研究的持续贡献，同时突出了分子信息在该领域日益增长的影响。作为对过去研究的当前总结，我们的超级树强调了未来工作的机会，同时朝着最终整合数据和特征本身迈出了一步。
