Dating of divergences within the Rattus genus phylogeny using whole mitochondrial genomes
The timing and order of divergences within the genus Rattus have, to date, been quite speculative. In order to address these important issues we sequenced six new whole mitochondrial genomes from wild-caught specimens from four species, Rattus exulans, Rattus praetor, Rattus rattus and Rattus tanezu...

The timing and order of divergences within the genus Rattus have, to date, been quite speculative.
