The paragraph below comes from another thread. It focuses on the oddities of Australia’s mammals.
4) Then we have the Australian populations of mammals which until relatively recently, were all marsupials (the placental mammals that once lived there went extinct long ago). Apparently the marsupials in Australia, being isolated from placental evolution going on in the rest of the world, was protected from competition from the more robust placental mammals. And in the rest of the planet, only a handful of marsupials were able to compete against the other mammals (like the possum).
5) The YEC explanation for this pattern (Australian Marsupials vs. Placentals beyond Australia) does not exist. YEC’s would essentially have to propose the following sequence:
a) The Great Flood kills all animals in Australia and elsewhere.
b) When the animals are released from the Ark, the marsupial mammals (even the slow ones) manage to travel directly to Australia before it separates from the main continent…
c) … while the placental mammals completely ignore Australia for generations.
This, of course, is an impossible scenario.
