一个多世纪以来，传统羊翅目中 5 个科（Furipteridae、Mystacinidae、Myzopodidae、Natalidae 和 Thiropteridae）的关系一直备受争议，导致了关于它们的进化和动物地理学的几种替代假设。最近对不同形态特征的分支评估和对线粒体脱氧核糖核酸（mtDNA）序列的另一项评估与传统的阳翅翅目分类和彼此之间的分类相矛盾。我们的目标是通过检查核基因（重组激活基因-2；Rag2）的 DNA 序列 (1.4 kb) 来测试替代系统发育假设，并在适当的情况下检查基于 Rag2 和 mtDNA 序列 (4.1 kb) 串联的科级关系。 Rag2 数据的简约性和贝叶斯分析表明的关系与 mtDNA 一致，并且组合分析为除 2 个进化枝之外的所有进化枝提供了高度统计支持。这些分子数据强烈支持Noctilionoidea（Furipteridae、Mormoopidae、Mystacinidae、Noctilionidae、Phyllostomidae和Thyropteridae）和Vespertilionoidea（Molossidae、Natalidae和Vespertilionidae），并且强烈反对Myzopodidae与其他noctilionoid或vespertilionoid家族之间的传统关联。这项研究、目前的分布和有限的化石记录强化了夜蛾总科起源于新大陆的假说，并暗示了Myzopodidae起源于旧大陆。尽管这些分子数据提供了相当多的统计支持，但仍需要对所有蝙蝠科进行广泛的分类采样进行进一步研究，以完全解决Myzopodidae、Noctilionoidea和Vespertilionoidea之间的关系。
Relationships of 5 families within traditional Yangochiroptera (Furipteridae, Mystacinidae, Myzopodidae, Natalidae, and Thyropteridae) have been debated considerably for more than a century, resulting in several alternative hypotheses for their evolution and zoogeography. A recent cladistic assessment of diverse morphologic traits and another of mitochondrial deoxyribonucleic acid (mtDNA) sequences have contradicted both traditional classification of yangochiropterans and each other. Our goals were to test alternative phylogenetic hypotheses by examining DNA sequences (1.4 kb) from a nuclear gene (recombination-activating gene-2; Rag2) and, if appropriate, to examine family-level relationships based on concatenation of Rag2 and mtDNA sequences (4.1 kb). Relationships suggested by parsimony and Bayesian analysis of Rag2 data were congruent with mtDNA, and combined analysis afforded high statistical support for all but 2 clades. These molecular data strongly support Noctilionoidea (Furipteridae, Mormoopidae, Mystacinidae, Noctilionidae, Phyllostomidae, and Thyropteridae) and Vespertilionoidea (Molossidae, Natalidae, and Vespertilionidae) and strongly contradict traditional association between Myzopodidae and other noctilionoid or vespertilionoid families. This study, current distributions, and limited fossil record strengthen the hypothesis of a New World origin for Noctilionoidea and suggest an Old World origin for Myzopodidae. Despite considerable statistical support afforded by these molecular data, further study using extensive taxonomic sampling of all bat families is needed to fully resolve relationships among Myzopodidae, Noctilionoidea, and Vespertilionoidea.
