人们普遍认为，中欧和北方欧洲是在末次冰期末从地中海避难所开始的范围扩张的殖民地。来自不同物种的数据支持这种情况，但我们质疑其普遍性我们对三种广泛分布的小型哺乳动物的线粒体DNA研究表明，殖民可能发生在中欧-西亚的冰川避难所。地中海半岛的单倍型与其他地方的单倍型不同。而不是有助于欧洲的冰川期后殖民化，地中海人口广泛的小型哺乳动物可能代表长期隔离经历异域物种形成。这可以解释与地中海半岛有关的小型哺乳动物的高度特有性。
There is a general perception that central and northern Europe were colonized by range expansion from Mediterranean refugia at the end of the last glaciation. Data from various species support this scenario, but we question its universality Our mitochondrial DNA studies on three widespread species of small mammal suggest that colonization may have occurred from glacial refugia in central Europe-western Asia. The haplotypes on the Mediterranean peninsulae are distinctive from those found elsewhere. Rather than contributing to the postglacial colonization of Europe, Mediterranean populations of widespread small mammals may represent long-term isolates undergoing allopatric speciation. This could explain the high endemism of small mammals associated with the Mediterranean peninsulae.
