Interspersed repeats that emerged at different evolutionary times are informative in mammalian phylogeny. Here we show that the ancient short interspersed elements (SINEs) ARE1 and ARE2 are abundantly present in the genomes of artiodactyls and cetaceans but not in other mammalian genomes. This supports the classification of the cetaceans with the artiodactyls by a shared character that is unlikely to be the result of convergence.
在不同进化时期出现的散布重复序列在哺乳动物系统发育研究中具有参考价值。我们在此表明,古老的短散布元件(SINEs)ARE1和ARE2大量存在于偶蹄目动物和鲸目动物的基因组中,而在其他哺乳动物基因组中则不存在。这支持了鲸目动物与偶蹄目动物通过一个共同特征进行分类,而这个特征不太可能是趋同进化的结果。
