Genetic differentiation of 35 vole species, estimated at 18 to 31 biochemical loci, allowed us to identify the following phyla of the tribe level: Lemmini, Dicrostonychini, Ellobiini, Clethrionomyini, and Microtini. Average genetic differentiation between the tribes (D'Nei = 0.977) corresponds to separation of the phylogenetic branches in the middle Pleistocene. Tribe Lagurini was shown to be contained within Cletrionomyini. Ondatrini was the first branch that diverged from the common stem in the Miocene (D = 1.563), prior to the formation of the Arvicolidae family. Distribution of genetic distances indicates that family radiations comprised two stages, tribal (Pliocene) and specific (Pleistocene). Ages of the taxa, estimated by means of the molecular clock, agreed well with stratigraphic data. Marked periodicity of divergence in the family confirms the concept of punctuated evolution.
通过对35种草甸田鼠物种在18至31个生化位点上的遗传分化进行估计，我们得以识别出以下部落级别的门类：田鼠亚科（Lemmini）、双毛田鼠族（Dicrostonychini）、椭圆背鼠族（Ellobiini）、棕背田鼠族（Clethrionomyini）和姬鼠族（Microtini）。部落之间的平均遗传分化（D'Nei = 0.977）与更新世中期系统发育分支的分离相对应。结果显示拉古尔鼠族（Lagurini）包含在棕背田鼠族（Cletrionomyini）之中。水䶄族（Ondatrini）是在中新世从共同主干分歧出来的第一个分支（D = 1.563），早于田鼠科的形成。遗传距离的分布表明科的辐射包括两个阶段，部落阶段（上新世）和物种阶段（更新世）。通过分子钟估计的分类单元年龄与地层数据吻合良好。该科中明显的分歧周期性证实了间断进化的概念。
