Retroposon analysis of major cetacean lineages: The monophyly of toothed whales and the paraphyly of river dolphins.
SINE (short interspersed element) insertion analysis elucidates contentious aspects in the phylogeny of toothed whales and dolphins (Odontoceti), especially river dolphins. Here, we characterize 25 informative SINEs inserted into unique genomic loci during evolution of odontocetes to construct a cla...
