Homoplasy of Retrotransposon Insertions in Toothed Whales.

ABSTRACT: Retrotransposon insertion patterns facilitate a virtually homoplasy-free picture of phylogenetic history. Still, a few most likely random parallel insertions or deletions result in rare cases of homoplasy in primates. The following question arises: how frequent is retrotransposon homoplasy in other phylogenetic clades? Here, we derived genome insertion data of toothed whales to evaluate the extension of homoplasy in a representative laurasiatherian group. Among more than a thousand extracted and aligned retrotransposon loci, we detected 37 cases of precise parallel insertions in species that are separated by over more than 10 million years, a time frame which minimizes the effects of incomplete lineage sorting. We compared the phylogenetic signal of insertions with the flanking sequences o
