Yellow-throated marten\'s relationship is between Stone marten and Fisher marten.Fisher marten is the first species who was divided from Martes.The second one were Yellow-throated marten and Stone marten.Based on the analysis of the fossil note,Martes came from Central Europe,Fisher marten,Yellow-throated marten and Stone marten belonged to a branch which evolved to temperate zone.Boreal forest martens was another branch which evolved to cold environment.It is suggested that Yellow-throated marten and Fisher martenwere ascertained genus separately.4、By contrasting and analyzing 11 complete mitochondrial control region gene sequences of Mustelidae,the extended termination associated sequence domain、the central domain and the conserved sequence block domain were identified.A extended termination associated sequence(ETAS1) and eight conserved sequence(CSB-F、E、D、C、B、1、2、3) was indicated,and sequence mode was presented.Different kind of short repeat sequences were found between CSB1 and CSB2.With wolf as the outgroup,the phylogenetic evolution relationship of Mustelidae was analyzed using the neighbor-joining method.

而基于鼬亚科动物线粒体DNA12种重链编码蛋白基因序列及石貂和渔貂线粒体ND2和cyt b全序列，以狼、狗獾和水獭为外类群，应用NJ、MP和ML法构分别构建貂属和貂熊的系统进化树，结果表明：紫貂与日本貂亲缘关系较美洲貂近，石貂与真貂亚属亲缘关系较近，黄喉貂介于石貂和渔貂之间；渔貂是最早从貂属分化出的种类，其次是黄喉貂和石貂；结合化石记录分析，貂属起源于中欧地区，渔貂、黄喉貂和石貂属于一个向温带进化的分支，而真貂亚属为另外一个向寒冷环境进化的分支，建议将黄喉貂和渔貂分别定为单独的属。4、比对并分析11种鼬科动物线粒体DNA控制区序列，识别出延长终止序列区、中央区和保守序列区3个区域，指出了一个终止相关序列ETAS1及8个保守序列(CSB-F、E、D、C、B、1、2和3)，并给出了序列通式，在CSB1和CSB2之间发现具有不同形式的短串联重复序列。
