Question

Why does Australia have so many unusual native animals, such as kangaroos and wombats?​

Answer 1

Answer:

Australia has a unique fauna because it was isolated from the rest of the world for very long periods. The Australian continent was surrounded by ocean for many millions of years, and so the plants and animals on that very large life-raft were able to evolve in distinctive ways.

Out of 300-some terrestrial mammal species in Australia, nearly 90 percent of them are found only in Australia (barring captivity and human introduction elsewhere). Beyond that, some reports show 70 percent of the birds and nearly 90 percent of reptiles are also endemic to the country, according to Tom Stalf, president and CEO of the Columbus Zoo and Aquarium.
