安乐蜥蜴 (anoles) 是进化和生态学方面的教科书研究生物。尽管变色龙的研究已经阐明了进化生物学中的几个主题，但由于该群体的系统发育信息有限，某些领域的进展受到阻碍。在这里，我们对所有 379 个现存安乐蜥属物种进行了系统发育分析，其中包括 139 个物种的新系统发育数据，包括 101 个物种的新 DNA 数据。我们使用所得的估计作为根据系统发育命名法原则定义变色蜥进化枝名称的基础，并检查变色蜥的生物地理学历史。我们的新分类学处理实现了最近变色龙细分的假定优势，这些细分采用了基于林奈排序的命名法，同时避免了这些方法中关于排序施加的人为限制的陷阱。我们的生物地理学分析表明变色蜥蜴传播历史的复杂性，包括多次穿越巴拿马地峡、两次入侵加勒比海、单次入侵牙买加和古巴，以及一次从加勒比海到大陆的进化扩散，从而导致变色蜥蜴的多样性。我们对变色龙的全面系统发育估计应该有助于严格测试许多比较进化假设。
Anolis lizards (anoles) are textbook study organisms in evolution and ecology. Although several topics in evolutionary biology have been elucidated by the study of anoles, progress in some areas has been hampered by limited phylogenetic information on this group. Here, we present a phylogenetic analysis of all 379 extant species of Anolis, with new phylogenetic data for 139 species including new DNA data for 101 species. We use the resulting estimates as a basis for defining anole clade names under the principles of phylogenetic nomenclature and to examine the biogeographic history of anoles. Our new taxonomic treatment achieves the supposed advantages of recent subdivisions of anoles that employed ranked Linnaean-based nomenclature while avoiding the pitfalls of those approaches regarding artificial constraints imposed by ranks. Our biogeographic analyses demonstrate complexity in the dispersal history of anoles, including multiple crossings of the Isthmus of Panama, two invasions of the Caribbean, single invasions to Jamaica and Cuba, and a single evolutionary dispersal from the Caribbean to the mainland that resulted in substantial anole diversity. Our comprehensive phylogenetic estimate of anoles should prove useful for rigorous testing of many comparative evolutionary hypotheses.
