兔形目是鼠兔科（鼠兔科）和野兔加兔科（野兔科）的统一目。基于传统形态学或分子序列数据对兔科内物种的系统发育重建为相互冲突的假设提供了支持。在这项研究中分析的逆转录酶的存在/不存在模式显示了强有力的支持广泛接受的分裂的兔形动物成ochotonids和leporids与Pronolagus作为第一个分歧的leporid树。此外，逆转录酶的存在/不存在模式嵌套罕见的火山兔，Romerolagus diazi，在一个未解决的网络更深的leporid关系，并提供了第一个无同源性的图像不完整的谱系排序和/或祖先杂交/渗入快速辐射Leporidae。同时，最强的逆转录酶存在/不存在的信号支持火山兔作为一个单独的分支之间的Pronolagus交界处和一个统一的集群的其余leporids。
Abstract The order Lagomorpha unifies pikas (Ochotonidae) and the hares plus rabbits (Leporidae). Phylogenetic reconstructions of the species within Leporidae based on traditional morphological or molecular sequence data provide support for conflicting hypotheses. The retroposon presence/absence patterns analyzed in this study revealed strong support for the broadly accepted splitting of lagomorphs into ochotonids and leporids with Pronolagus as the first divergence in the leporid tree. Furthermore, the retroposon presence/absence patterns nested the rare volcano rabbit, Romerolagus diazi, within an unresolved network of deeper leporid relationships and provide the first homoplasy-free image of incomplete lineage sorting and/or ancestral hybridization/introgression in rapidly radiated Leporidae. At the same time, the strongest retroposon presence/absence signal supports the volcano rabbit as a separate branch between the Pronolagus junction and a unified cluster of the remaining leporids.
