非洲兽是一个巨大的各种哺乳动物的集合体，包括六个曾经被归类为远亲群体的目。这种超序关系可能是由于1.05亿至4000万年前冈多瓦纳大陆的分裂以及非洲大陆的孤立。虽然最近的分子研究很好地支持了非洲兽目的单系性，但非洲兽目哺乳动物之间的相互关系仍然不清楚。在这项研究中，我们确定了完整的线粒体基因组序列的蹄兔，金鼹鼠，和象鼩。这些序列进行了比较与其他真兽类，以分析非洲兽类，特别是paenungulates之间的系统发育关系。我们的线粒体基因组分析支持特提斯的单系性。(C)2003 Elsevier Science（美国）。All rights reserved.
Afrotheria is a huge assemblage of various mammals encompassing six orders that were once classified as distantly related groups. This superordinal relationship may have resulted from the break-up of Gondowanaland followed by the isolation of the African continent between 105 and 40 million years ago. Although the monophyly of Afrotheria is well supported by recent molecular studies, the interrelationships within afrotherian mammals remain unclarified. In this study, we determined the sequence of the complete mitochondrial genomes of hyrax, golden mole, and elephant shrew. These sequences were compared with those of other eutherians to analyze the phylogenetic relationships among afrotherians and, in particular, those among paenungulates. Our mitochondrial genome analysis supports the monophyly of Tethytheria. (C) 2003 Elsevier Science (USA). All rights reserved.
