| Outline of Final Research Achievements |
Japanese wolves (Canis lupus hodophilax, Temminck, 1839) has been called as Ookami or Jamainu. We examined mitochondrial DNA (mtDNA) sequences from five Japanese wolf specimens found in Japan, three specimens from Museum fur Naturkunde in Berlin and three specimens (Jentink a, Jentink b and Jentink c) in Siebold collection of Naturalis Biodiversity Center in Leiden. The mitochondrial genome of the type specimen of hodophilax (Jentink c) called as Jamainu in the Siebold collection was included in the cluster of Japanese wolves. Although mitochondrial lineage of Jentink c is Japanese wolf, the morphological features and the size of Jentink c specimen are different from those of other Japanese wolves indicates that the crossbreed events between Japanese wolves and domestic dogs might be occurred in the past.

シーボルトが蒐集した標本を含めて海外の博物館に保管されているニホンオオカミの標本のmtDNA解析は、本研究が初めてである。これまでシーボルトコレクションのヤマイヌの正体は不明であったが、本研究によりヤマイヌはニホンオオカミ型のmtDNAを有することが明らかとなった。これにより、当時ヤマイヌと呼ばれていた動物は、ニホンオオカミかあるいはイヌとの交雑種であることが示された。
