Why does Australia have unique fauna compared to the rest of the world?
This high level of endemism can be attributed to the continent's long geographic isolation, tectonic stability, and the effects of an unusual pattern of climate change on the soil and flora over geological time. A unique feature of Australia's fauna is the relative scarcity of native placental mammals.
Why are Australia's indigenous species so unique?
