9508685 Meng This research involves the evolutionary relationships of rodents, lagomorphs and certain extinct taxa (Glires) both to one another and to other higher mammalian taxa. Data analyzed will include tooth enamel microstructure, dental, cranial and postcranial characters from fossil and recent gliriform mammals. Phylogenetic relationships will be reconstructed using computer assisted cladistic methods. %%% The significance of the study is one of providing testable hypotheses of higher level mammalian phylogeny as well as those of the origins and evolution of Glires, many of which are currently under rigorous debate. In addition, important new fossil material from Mongolia and China will be prepared and studied by direct observation and by scanning electron microscopy. ***

9508685 MENG这项研究涉及啮齿动物，龙虾型和某些灭绝的分类单元（Glires）的进化关系，以及其他较高的哺乳动物分类单元。分析的数据将包括化石和最近的胶状哺乳动物的牙齿搪瓷微观结构，牙齿，颅骨和颅后特征。系统发育关系将使用计算机辅助cladistic方法重建。 %%％200，这是提供高级哺乳动物系统发育的可检验的假设之一，以及毛刺起源和演变的假设，其中许多目前都处于严格的争论中。此外，将通过直接观察和扫描电子显微镜来准备和研究来自蒙古和中国的重要新化石材料。 ***
