Disentangling the relationship of the Australian marsupial orders using retrotransposon and evolutionary network analyses
The ancestors to the Australian marsupials entered Australia around 60 (54-72) million years ago from Antarctica, and radiated into the four living orders Peramelemorphia, Dasyuromorphia, Diprotodontia and Notoryctemorphia. The relationship between the four Australian marsupial orders has been a lon...
