- In order to answer this I have to relate back to my studies of Plate Tectonics.
- Australia was once connected to the rest of the world by land. Did you ever hear
- of Pangea? The pangean continent broke apart and Australia drifted away from the
- rest of the world before the evolution of placentals. Placentals evolved in the
- rest of the world while Australia was not connected to it by land.
-
- So you see, Marsupials were in Australia even before Placentals existed!
-
- Marsupials were overrun by placentals in the rest of the world because placentals
- were better equipped to compete for food & survival. Cats, rats & rabbits are
- doing to Australia's marsupial population today what placentals did to marsupials
- in the rest of the world a long time ago.

- Geuss my geology degree is good for something after all...
