Tasmania became covered by H2O due to sea degrees lifting and ice caps formed in Antarctica. Similar geological patterns were also noted among rocks in South America and Australia.

Australian Flora and Fauna: Lack of evidence to support that ice once covered the northern hemisphere suggests that the northern hemisphere was once at a more equatorial region million years ago and experienced a more tropical climate. Plants from the Proteaceae family exist in nearly all continents in the southern hemisphere and Australia has the greatest abundance of species.

B The recourses I used for this assessment were found to be reliable and valid. A Nimbadon was a big prehistoric tree brooding pouched mammal. Exact reasons for the extinction of Evolution of australian biota 2 essay remain unclear.

North Australia experienced warm conditions and South Australia experienced cool conditions. The Cassowary can grow up to 2 metres tall and weigh up to 76 kilograms.

The Australian Red Kangaroo came into existence around 25 million years ago, about 10 million years after Australia split from Antarctica, and preferred rainforest type environments. It is said that nimbadons became nonextant about 12 million old ages ago as a consequence of clime alteration which resulted in losingss of home ground for the nimbadons.

Typical Proteaceae Grevillea Fauna species: The Southern Cassowary is currently still a living species although is endangered with very little remaining in the wild. The cassowary has course like feathers, with a tall brown helmet like casque on its head and one of its 3 toes has a dagger shaped claw for scratching and fighting.

Species that had been widespread across Australia became restricted to non-arid sections in the north, south, west and east. The giant wombat preferred living in semi-arid plains, savannahs and open woodlands, and is generally absent from hilly, forested coastal regions but is also known for its liking of coastal locations.

Further the gradual drying of the continent over the last few million years has reduced the habitats of certain Proteaceae species reducing the abundance of species in certain areas. Around 12 million old ages ago Australia was floating north and this motion off from Antarctica and the South Pole resulted in drying of the Australian clime.

Proteaceae Grevillea The Grevillea species from the Proteaceae family is an example of a species of flora that has evolved to suit its environment; the Australian bush.

Evolution of Australian Biota Essay Paper

As a result of its isolation the Grevillea species developed its own characteristics and features independent from other Proteaceae species in the southern hemisphere.

Thus these isolated plants evolved independently from each other, becoming distinct species. As Australia became drier and woodlands slowly replaced rainforests around 15 million years ago, the kangaroo was forced to develop into a larger carnivorous animal living in open woodland environments.

During this period Australia separated from Gondwana but was still attached to Antarctica and was floating south quickly. The Grevillea demonstrates certain evolutionarily traits associated with these two factors, that is it has distinct features that are both different and similar to other Proteaceae species in Australia.
