灰狼（卡狼疮）最初居住在北方的主要地区，但许多当地种群灭绝了。日本狼有两个谱系，即日本狼和本州狼。I. hodophilax）和Ezo或北海道（C. I.在100年到120年前，哈泰狼迅速灭绝。在这里，我们分析了古代标本的完整线粒体基因组序列，并重建了两个灭绝亚种的殖民历史。我们显示了日本狼在狼的生殖系统中的独特地位，表明它们与其他灰狼种群长期分离。日本狼似乎在晚更新世（约1000年）殖民了日本群岛。25，000 - 125，000年前）。相比之下，Ezo狼，这是明确分开的日本狼在繁殖，可能是最近才到达日本（
The grey wolves (Cards lupus) originally inhabited major parts of the Northern hemisphere, but many local populations became extinct. Two lineages of wolves in Japan, namely, Japanese or Honshu (C. I. hodophilax) and Ezo or Hokkaido (C. I. hattai) wolves, rapidly went extinct between 100 and 120 years ago. Here we analyse the complete mitochondrial genome sequences from ancient specimens and reconstruct the colonization history of the two extinct subspecies. We show a unique status of Japanese wolves in wolf phylogeny, suggesting their long time separation from other grey wolf populations. Japanese wolves appeared to have colonized the Japanese archipelago in the Late Pleistocene (ca. 25,000-125,000 years ago). By contrast, Ezo wolves, which are clearly separated from Japanese wolves in phylogeny, are likely to have arrived at Japan relatively recently (
