We address the phylogenetic relationships of the drongos (Dicruridae) at the species-level using sequences from two nuclear (myoglobin intron-2 and c-mos) and two mitochondrial (ND2 and cytochrome b) loci. The resulting phylogenetic tree shows that the most basal species is D. aeneus, followed in the tree by a trichotomy including (1) the Asian D. remifer, (2) a clade of all African and Indian Ocean islands species as well as two Asian species (D. macrocercus and D. leucophaeus) and (3) a clade that includes all other Asian species as well as two Australasian species (D. megarhynchus and D. bracteatus). Our phylogenetic hypotheses are compared to [Mayr, E., Vaurie, C., 1948. Evolution of the family Dicruridae (Birds). Evolution 2, 238-265.] hypothetical family "tree" based on traditional phenotypic analysis and biogeography. We point out a general discrepancy between the so-called "primitive" or "unspecialized" species and their position in the phylogenetic tree, although our results for other species are congruent with previous hypotheses. We conduct dating analyses using a relaxed-clock method, and propose a chronology of clades formation. A particular attention is given to the drongo radiation in Indian Ocean islands and to the extinction-invasion processes involved. The first large diversification of the family took place both in Asia and Africa at 11.9 and 13.3Myr, respectively, followed by a dispersal event from Africa to Asia at ca 10.6Myr; dispersal over Wallace line occurred later at ca 6Myr. At 5Myr, Principe and Indian Ocean Islands have been colonized from an African ancestor; the most recent colonization event concerned Anjouan by an immigrating population from Madagascar.
我们利用两个核基因座（肌红蛋白内含子2和原癌基因c-mos）以及两个线粒体基因座（ND2和细胞色素b）的序列，在物种水平上研究了卷尾科鸟类的系统发育关系。由此得到的系统发育树表明，最基部的物种是铜色卷尾，在树中接下来是一个三分枝，包括（1）亚洲的白喉卷尾，（2）一个包含所有非洲和印度洋岛屿物种以及两个亚洲物种（大盘尾和白脸卷尾）的分支，以及（3）一个包含所有其他亚洲物种以及两个澳大拉西亚物种（大卷尾和黑卷尾）的分支。我们将我们的系统发育假设与[迈尔，E.，瓦里，C.，1948年。卷尾科（鸟类）的进化。《进化》2，238 - 265。]基于传统表型分析和生物地理学的假设科“树”进行了比较。我们指出了所谓“原始”或“非特化”物种与其在系统发育树中的位置之间的总体差异，尽管我们对其他物种的结果与先前的假设一致。我们使用宽松分子钟方法进行了定年分析，并提出了分支形成的年表。特别关注了印度洋岛屿上卷尾的辐射以及所涉及的灭绝 - 入侵过程。该科的首次大规模多样化分别在亚洲和非洲发生于1190万年前和分别在1330万年前，随后在约1060万年前发生了从非洲到亚洲的扩散事件；越过华莱士线的扩散后来在约600万年前发生。在500万年前，普林西比岛和印度洋岛屿由一个非洲祖先殖民；最近的殖民事件涉及昂儒昂岛，是由来自马达加斯加的一个迁入种群完成的。
