虽然自1817年Rafinesque首次描述现存物种Aplodontia rufa（山海狸）以来，已经描述了超过100种的化石Aplodontoids，但自1941年McGrew的研究以来，还没有对该分支中所有物种之间的关系进行过彻底的调查。在这里，一个完整的系统发育分析的所有已公布的种aplodontoids是用来重建进化关系内的分支，并提出一个更新的分类Aplodontoidea。几个传统上公认的亚科被发现是并系的，即Prosciurinae，Allomyinae和Meniscomyinae。然而，其他物种，包括单齿象亚科和鼠科，似乎是单系的。这后两个类群，其中包括所有的hypsodont成员的aplodontoid分支，似乎是姐妹类群。单齿类分支的历史显示了在早渐新世、晚渐新世和早中新世至中新世的几个快速多样化的事件。Ansomyinae和Aplodontinae的物种形成率相对较低。形态学和进化速率的变化模式表明，需要更详细的研究多样化，灭绝和生态变化的原因在这个谱系。(C)2008年，伦敦林奈学会。
Although over a hundred species of fossil aplodontoids have been described since the extant species, Aplodontia rufa (the mountain beaver), was first described by Rafinesque in 1817, a thorough survey of the relationships among all the species in this clade has not been undertaken since McGrew's study in 1941. Here, a complete phylogenetic analysis of all published species of aplodontoids is used to reconstruct the evolutionary relationships within the clade, and to present an updated classification of the Aplodontoidea. Several of the traditionally recognized subfamilies are found to be paraphyletic, namely the Prosciurinae, the Allomyinae, and the Meniscomyinae. Others, however, including the Aplodontinae and the Mylagaulidae, appear to be monophyletic. These latter two taxa, which include all of the hypsodont members of the aplodontoid clade, seem to be sister taxa. The history of the aplodontoid clade shows several episodes of rapid diversification in the Early Oligocene, the Late Oligocene, and the Early to Middle Miocene. The Ansomyinae and Aplodontinae show comparatively low speciation rates. The patterns of change in morphology and evolutionary rates suggest a need for a more detailed study of the causes of diversification, extinction, and ecological change in this lineage.
