Kimberley rock rat

The Kimberley rock rat (Zyzomys woodwardi) is a species of rodent in the family Muridae. It is found only in Australia. It is specifically found in northern tropical part of the northern territory and adjacent Kimberley division of west Australia in high altitude closed forest. Biologist predicted that Zyzomys Woodwardi speciated from Zyzomys Arugurus around 8000 years ago due to a large flood that increased the wetness of the environment. In response to the wetter environment Zyzomys Woodwardi had a better Darwinian fitness and outcompeted Zyzomys Arugurus due to new selective pressures and over time the two species were separated by large vine thickets and sandstone barriers.
