Mitochondrial (cytochrome b, 12S rRNA) and nuclear (IRBP, RAG1) gene sequences were determined in various species of small mammals including mustelids, talpids, and murids (e.g., the Old World murine genera Mus, Apodemus, and Rattus). In the case of Mus, for example, phylogenetic analysis of the newly and previously available sequences support recognition of four subgenera within Mus (Mus, Coelomys, Nannomys, and Pyromys), with an unresolved basal polytomy. Our data further indicate that the subgenus Mus contains three distinct 'species groups': (1) a Mus booduga Species Group, also including Mus terricolor and Mus fragilicauda (probably also Mus famulus); (2) a Mus cervicolor Species Group, also including Mus caroli and Mus cookii; and (3) a Mus musculus Species Group, also including Mus macedonicus, Mus spicilegus, and Mus spretus. Species diversity in Eurasian Mus is probably explicable in terms of several phases of range expansion and vicariance, and by a propensity within the group to undergo biotope transitions. IRBP and RAG1 molecular clocks for Mus date the origin of subgenera to around 5-6 mya and the origin of Species Groups within subgenus Mus to around 2-3 mya. The temporal pattern of evolution among Eurasian Mus is more complex than that within the Eurasian temperate genus Apodemus.

在各种小型哺乳动物中测定了线粒体（细胞色素 b、12S rRNA）和核（IRBP、RAG1）基因序列，包括鼬科动物、鼠科动物和鼠科动物（例如旧大陆鼠属 Mus、Apododemus 和 Rattus）。以小鼠为例，对新的和以前可用的序列的系统发育分析支持对小鼠内四个亚属（Mus、Coelomys、Nannomys 和 Pyromys）的识别，但基础多分性尚未解决。我们的数据进一步表明，Mus亚属包含三个不同的“物种组”：（1）Mus booduga物种组，还包括Mus terricolor和Mus fragilicauda（可能也包括Mus famulus）； (2) 一个Mus cervicolor物种群，还包括Mus caroli和Mus Cookii； (3)小家鼠种群，还包括小家鼠(Mus macedonicus)、小家鼠(Mus spicilegus)和小家鼠(Mus spretus)。欧亚鼠的物种多样性可能可以通过范围扩张和变异的几个阶段以及群体内经历生境转变的倾向来解释。 Mus 的 IRBP 和 RAG1 分子钟将亚属的起源追溯到大约 5-6 mya，将 Mus 亚属内的物种组的起源追溯到大约 2-3 mya。欧亚鼠属的进化时间模式比欧亚温带姬鼠属的进化更为复杂。
