家鼠（Mus musculus）是世界上最普遍的入侵物种之一，在澳大利亚尤为常见和广泛，但它最初来自哪里仍然未知。在这里，我们通过线粒体 DNA 序列（D 环）的系统发育地理学分析来研究这一起源，比较来自澳大利亚的小鼠群体与来自西欧可能的区域来源地区的小鼠群体。我们的研究结果与人类历史关联一致，显示了澳大利亚和不列颠群岛之间的紧密联系。这一结果具有内在和应用意义，有助于验证小鼠的殖民历史作为人类定居历史的代表。
The house mouse, Mus musculus, is one of the most ubiquitous invasive species worldwide and in Australia is particularly common and widespread, but where it originally came from is still unknown. Here we investigated this origin through a phylogeographic analysis of mitochondrial DNA sequences (D-loop) comparing mouse populations from Australia with those from the likely regional source area in Western Europe. Our results agree with human historical associations, showing a strong link between Australia and the British Isles. This outcome is of intrinsic and applied interest and helps to validate the colonization history of mice as a proxy for human settlement history.
