Phylogenetic origin of Passeriformes, Falconiformes and Gruiformes based on retroposon insertions

利用斑雀(Taeniopygia Guttata)的全基因组数据和秃鹰的BAC序列进行回溯带插入分析，以揭示鸟类的系统发育关系。这项研究发现，Raptores是多种多样的，Neoaves的祖先在很短的时间内就出现了向更高阶谱系的分化。此外，通过系统发育分析，发现了一个名为“核心群”的单系支系，该支系具有5个反转录基因插入位点。这项研究揭示了新鸟类复杂的进化史。

Retoropozon insertion analysis was performed to reveal the phylogenetic relationships in Aves by using the whole genomic data of zebrafinch(Taeniopygia guttata) and the BAC sequence of condor. This study found that Raptores are polyphyletic and that divergence of Neoaves ancestor into higher-order lineages occurred in a short period of time. In addition, the phylogenetic analysis of Gruiformes identified a monophyletic clade called "core-group" with five retroposon insertion loci. This study revealed a complicated evolutionary history of Neoaves.
