对青蛙 28S 核糖体 RNA 基因中 1656 个比对位点的系统发育分析支持了一些最近认识的高级无尾目类群，但也为其他类群提供了反支持。 28S rDNA 数据支持最近确认的Pipanura（中蛙类加新蛙类）的单系性，这又表明古蛙类的并系性。中蛙类（pelobatoids 加 pipoids），在形态学分析中要么被认为是并系群，要么被弱支持为单系群，也从 28S rDNA 数据中得到支持作为单系群。 Hyloidea（= Bufonoidea）被广泛认可，但缺乏形态学支持，得到一些分子支持，认为它是单系的。然而，Ranoidea 有形态学支持，却有核糖体 DNA 的反支持。特别是，树突虫不与兰科动物分类（但有时与舌状动物分类）。分子数据与 Duellman 和 Trueb（1986：Biology of Amphians）的形态学数据的综合分析支持 Pipanura、Mesobatrachia、Neobatrachia 和 Hyloidea，但显示ranoids 为并系群（Dendrobatidae 与 Hyloidea 相关）。无尾树的几个区域的分子和形态学数据之间的一致性表明传统上不稳定的高等青蛙分类已接近稳定。
Phylogenetic analysis of 1656 aligned sites in the 28S ribosomal RNA gene of frogs supports some of the recently recognized higher groups of anurans but provides counter-support for others. The 28S rDNA data support the monophyly of the recently recognized Pipanura (me- sobatrachians plus neobatrachians), which in turn indicates paraphyly of archaeobatrachians. Me- sobatrachians (pelobatoids plus pipoids), which are either considered paraphyletic or weakly sup- ported as monophyletic in morphological analyses, also receive support as a monophyletic group from the 28S rDNA data. Hyloidea (= Bufonoidea), which is widely recognized but lacks mor- phological support, receives some molecular support as being monophyletic. However, Ranoidea, which is supported by morphology, is counter-supported by ribosomal DNA. In particular, den- drobatids do not group with ranids (but sometimes group with hyloids). A combined analysis of the molecular data with the morphological data of Duellman and Trueb (1986:Biology of Am- phibians) supports Pipanura, Mesobatrachia, Neobatrachia, and Hyloidea, but shows the ranoids as paraphyletic (with Dendrobatidae related to Hyloidea). The agreement between molecular and morphological data in several regions of the anuran tree indicates an approaching stabilization of traditionally labile higher frog classification.
