非洲刺鼠(Acomys属)属于鼠科啮齿动物家族，其分类一直备受争议。形态数据表明，这一群体与真正的东半球小鼠属小鼠之间存在密切的亲缘关系。然而，免疫学、生化和DNA融化研究的综合结果表明，多刺小鼠甚至不应该被视为小鼠亚科的成员。为了进一步阐明多刺小鼠在啮齿动物系统发育树中的位置，我们对多刺小鼠类型物种Acomys cahirinus和其他五个有代表性的啮齿动物物种的583个核苷酸同源区进行了直接序列比较。我们的结果提供了无可辩驳的证据，支持了棘鼠与蒙古沙鼠的亲缘关系比与MLRS肌肉的亲缘关系更近的观点。
The classification of the African spiny mice (genus Acomys) within the Muridae family of rodents has been fraught with controversy. Morphological data suggest a close affinity between this group and true old world mice of the genus Mus. However, the combined results of immunological, biochemical, and DNA melting studies suggest that spiny mice should not even be considered as members of the Murinae subfamily. To further elucidate the position of the spiny mice within the rodent phylogenetic tree, we performed a direct sequence comparison of a 583-nucleotide homologous region from the spiny mouse type species Acomys cahirinus and five other representative rodent species. Our results provide incontrovertible evidence to support the contention that the spiny mouse is more closely related to the Mongolian gerbil Meriones unguiculatus than it is to Mlrs musculus.
