| 摘 要： | 鬣狗科动物曾是一个数量十分可观的群体,在5百万年前曾达到演化的鼎盛时期,留下已鉴定化石种100余种.现生的鬣狗科动物仅有4种,仅分布在亚洲和非洲部分地区.由于该科动物演化至今种类剧减、分布区退缩,部分化石种与现生种的谱系演化关系尚不明确,因此成为古生物学家和进化生物学家关注的生物类群之一.采用现代分子生物学方法,提取扩增河北秦皇岛灵仙洞中鬣狗类化石的线粒体基因组古DNA片段,通过与基因库中已有鬣狗科动物各属种同源序列的对比分析,从分子水平确定该化石为斑鬣狗化石;基于古DNA序列数据构建的系统进化树显示,该地的斑鬣狗个体与我国东北地区及俄罗斯的化石斑鬣狗具有较近的亲缘关系,而与西欧洞穴鬣狗及非洲现生斑鬣狗亲缘关系较远,显示出斑鬣狗演化的分子地理谱系.

| Abstract: | The extant hyena species are the remnants of a formerly diverse group of Hyaenidae,which reached its peak about 5 MYA and contained more than 100 fossil species. Hyenas have been the subject of a number of evolutionary and systematic studies during the last two centuries,due in large part to the dramatical loss of its diversity and geography. The phylogenetic studies incorporating both morphological and molecular analysis have yielded different conclusions regarding the evolutionary relationship between ext... |
