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.

利用斑胸草雀（Taeniopygia guttata）的全基因组数据和秃鹰的BAC基因序列，对鸟类进行了Retoropozon插入分析，以揭示鸟类的系统发育关系。本研究发现，猛禽类是多系的，新鸟类祖先分化成高阶谱系发生在很短的时间内。此外，系统发育分析确定了一个单系分支称为“核心组”与五个逆转录酶插入位点。这项研究揭示了新鸟纲动物复杂的进化历史。
