所谓的 Glires 假说假设啮齿类动物（例如大鼠和小鼠）和兔形目动物（例如兔子）之间存在姐妹群关系。最近的分子系统发育分析产生了不一致的结果，要么支持要么反驳 Glires 分组。为了研究这种不一致，我们根据 20 个直系同源核蛋白编码基因（6441 个氨基酸位点）和 12 个线粒体蛋白编码基因（3559 个氨基酸位点）的数据集重建了系统发育树。核数据集的规模比迄今为止用于研究 Glires 概念的任何类似数据集都要大得多。核数据分析强烈支持系统发育树（青蛙，鸡，（（大鼠，小鼠），（兔子，（人类，（牛，狗））））），而发情数据无法最终确定兔子相对于人类的位置。这一结果得到了所有方法的支持。因此，本研究否定了 Glires 假说。 (C) 2003 年爱思唯尔科学（美国）。版权所有。
The so-called Glires hypothesis postulates a sister-group relationship between Rodentia (e.g., rat and mouse) and Lagomorpha (e.g., rabbit). Recent molecular phylogenetic analyses have yielded incongruent results, and either supported or refuted the Glires grouping. In order to study this inconsistency we have reconstructed phylogenetic trees based on data sets of 20 orthologous nuclear protein coding genes (6441 aa, sites) and 12 mitochondrial protein coding genes (3559 aa sites). The size of the nuclear data set is considerably larger than any comparable data set hitherto used to study the Glires concept. Analysis of the nuclear data strongly supported the phylogenetic tree (frog, chicken, ((rat, mouse), (rabbit, (human, (cattle, dog))))), while the rut data could not conclusively resolve the position of rabbit relative to that of human. This result was supported by all methods. Thus, the Glires hypothesis was rejected by this study. (C) 2003 Elsevier Science (USA). All rights reserved.
