Is there any correlation between Australia's uranium deposits and the unique animals? Australian animals are very different than the rest of the world. I wonder if the radiation of Australia's Uranium deposits have anything to do with why animals uniquely evolved? For instance, marsupials have three vaginas and platypus are one of the only mammals that lay eggs.

If not Uranium what makes them so different?

No. The reason for Australia’s unique evolution is that it was relatively isolated from the rest of the world.

Australia isn’t too radioactive either. The fact that it has more uranium deposits than other countries is that it’s huge.
