The nucleotide sequence of an extended mitochondrial genome segment (11473 base pairs in size) was determined in the wolverine (Gulo gulo) from Magadan oblast. Phylogenetic and statistical analyses of mitochondrial DNA (mtDNA) sequences of mustelids showed that the separation of the Gulo phylogenetic branch occurred at the Miocene--early Pliocene (about 5.6 million years ago (MYA)), while the formation of the species G. gulo took place in the Middle Pleistocene (181 and 234 thousand years ago (KYA), according to the results of molecular dating based on the variability of the extended mtDNA segment and the mitochondrial cytochrome b gene, respectively). The molecular data were in agreement with the fossil records for wolverines.
测定了来自马加丹州的狼獾（貂熊属貂熊种）一段扩展线粒体基因组片段（大小为11473个碱基对）的核苷酸序列。对鼬科动物线粒体DNA（mtDNA）序列的系统发育和统计分析表明，貂熊系统发育分支的分离发生在中新世 - 上新世早期（约560万年前（MYA）），而貂熊种的形成发生在中更新世（分别根据基于扩展mtDNA片段和线粒体细胞色素b基因变异性的分子定年结果，为18.1万和23.4万年前（KYA））。分子数据与狼獾的化石记录一致。
