来自外群、个体发育、新生物和化石的证据被用来区分17个现代目中真兽骨动脉主要组成部分的原始和衍生特征状态。派生状态支持以下更高层次的系统发育假说:(1)小翼手目的和大翼手目的是单系+ADS-和(2)在钩纲内,管翅目是其余现代目的外类群,其次是偶蹄目和鲸目。腓动脉的三个分支,即枕大动脉、颞支和后支,在以前的合成中几乎被忽略,被证明是真足动脉和羊膜动脉的原始分支。
Evidence from outgroups, ontogeny, neontology, and fossils is used to distinguish primitive and derived character states for the major components of the eutherian stapedial artery in 17 modern orders. Derived states support the following higher-level phylogenetic hypotheses: (1) Microchiroptera and Megachiroptera are monophyletic+ADs- and (2) within Ungulata, Tubulidentata is the outgroup to the remaining modern orders, followed in succession by Artiodactyla and then Cetacea. Three branches of the stapedial artery, the a. diploetica magna, ramus temporalis, and ramus posterior, all but neglected in previous syntheses, are shown to be primitive for Eutheria and Amniota.
