Inference of phylogenetic relationships based on insertions of retroposons
We analyze phylogenetic relationships of many animals.
To understand phylogenetic relationships, it is indispensable to understands how these animals evolved and diverged to yield various species.
We use a unique technique based on insertion of the SINE, which is one of the transposable elements dispersed among the genome of various animals.
This method gives us phylogenetic trees with higher confidence compared with the ordinary analyses.
We are currently investigating the phylogenetic relationships of various animals from mammals (whales, dolphins, bats, hedgehogs, and moles), birds (penguins) and reptiles (tortoises).
