Why are kangaroos found only in Australia? Why didn’t they become an invasive species on different continents?
In: Earth Science
It’s worth a Google if you’re really interested, and I’m heavily simplifying it, but the Australian continent broke apart and separated from the other land masses and drifted far away, isolating it’s species from the rest of the world, allowing diversion on a scale not seen elsewhere.
Most of the unique species on Australia like Kangaroos are unique to Australia for exactly that reason.
Although if I recall right, there’s been identifcation of marsupials on other Australasian islands. And I think a small species was identified in Sri Lanka. Citation needed.
