Why Are There So Many Unique Animals In Australia
The answer is actually simple.
Why are there so many unique animals in australia. Australia probably has between 200000 and 300000 species about 100000 of which have been described. Half of the birds that live in Australia can only be found there. Many of the plants like the animals.
As a result many of the animals in this place exhibit unique characteristics and survival techniques. Because Australia has been isolated from the rest of the world for many thousands of years. Others are dangerous because they have deadly venom like some kinds of snakes.
Australia was part of Gondwana the huge super-continent of the southern hemisphere. Australia is the kingdom of marsupials home to furry kangaroos koalas and wombats. This high level of endemism is a result of Australias long period of isolation from other continents since its separation from Gondwana about 40 million years ago.
There are so many unique Australian animals because Australia is on a continent that is pretty far from other continents. The lack of dissimilarities and the occurrence of unique animal or plant assemblages in various parts of the world not just Australia may be evidence for a rapid resettlement in relatively recent. The reason Australia has such unique animals was its long isolation from the rest of the world.
The continent of Australia has vast expenses of desert and semi-arid land in its interior sub-tropical rain forest in the Northeast. It is because Australia is an island. Due to this isolation and the lack of predators Australias unique fauna developed.
Sea levels were much lower than today. Charles Darwin already answered it when he visited the Galapagos islands. In Australia alone there are more than 378 mammal species 828 bird species 4000 fish species 300 species of lizards 140 snake species two crocodile species and around 50 types of marine mammals according to Australia.
