Australian Fauna
1. World Isolation
The prime, and most logical explanation of the diversity surrounding the Australian ecosystem woud be in effect of it's geological location. The entire continent- is technically situatated as a large land mass surrounded by the Southern Pacific Ocean. In simplication- the terrian is soley "one huge continental island". This topographic environement sets as an immense world-communication drawback. Australia has considerablly been limited all sources of land's intercontinental evolution, and foriegn immigrant income. This locality of the continent has made the immigtaion of non-native species little to near impossible during the early ages. This world-wide isolation that the contient suffers a major dissadvantage of - was first originated in the late Paleozoic and early Mesozoic eras. Back in the the time of the existence of Gondwana, super continent began to drift apart. This created the shifting of the land mass so known today as "Australia" further in the South East Ocean. Resulting from this was detachation from any other "terra-firma" transmission, and communication. Geographically, it had now been seperated from any other land-connections. Over millenia, Australia's universal position has obviously effected it's native fuanic and floric species. Stranding the wildlife and vegitation on thus lone territory, it had enforced them to adapt and evolve over the years of confinment. Therby it's stature of being an island, had condemned a majority of the continent's land inhabitants, and most avifuana to the desolate country. The same still apllies to all outside species in neighboring countries. This severe lack of outside migration has allowed the continent's natives to exclusively breed and flourish unimpeded. This atypical evolution of an entire ecosytem- developed only by the general and sole population of the endemic species, have grown throughout age to be one of the most un-genetically modified habitations in the world. This has however, set a utmost biodiversity in the mileu compared to the rest of the world. What comes to Australia- stays in Australia.
2. Climate
The second most- and rational statement about Australia's orgin of biological structure is the land's extreme weather conditions. Further and more deeply expalined on the environmental page, the Australian continent has consisted of hot and sporatic weather systems. Little to no rain has fallen across the lands interior for decades. Not only does Aussie land supply the world with an idiosyncratic endemicity in it's wildlife, but also has attributed as one of the nations most naturally distinguishing envionmental habitats. More on the focus of the native's inability to convey beyond their homeland- is the particular ecological conditions of Australia. This has further-more prevented alien species from emigrating to the country- unable to withstand such a dramatic ecosystem. The formal evolutions and adaptations made by aborignes were not ascribed to forigner species, creating a harsher environment for new settlers. For what little of outside species that sucsessfully managed to arrive, only about 20% were able to genetically modify to more suitably fit the environment. This cause of such an unstable environ had eventually led to the fuana climatically adaptating to thier ecosystem. These animals have generated a stability with their climate over the most evolutionizing periods of time. By physically and heritably maturing themselves to thier evironment, the autochthon species of Australia have made a biological break-through for the planet's natured complexion.
3. Fertality
The Third, but most argiculturally premeir reason for the fuana's 'darwinism' is also tied in with the ecosystem that the continent provides- able to substain life source. This principal however holds as a great significant factor to the life of the continent. Fertality provides a source of vegitation and water- vital to the naturally broiling climate. Since the beginning of industrialazion, rich fertality in a land has promsised for a effective, and efficient method of sturcturing life of any kind. This has expecially become servicable for the mainly dry continent of Australia. Fecund fertalization along the coastlines of the land have made a suitable habitat for endemic animals- and as well as humans to survive and surge among the land "down under." The high fertality rates of the land have lead to fast and capable reproduction of the unhampered animals and planets belonging to the continent. The productiveness of producing goods has provided the inhabitants with a food source. Also, this has been essentially important to the wildlife because of all the internal desolate land, incapible of manufacturing crops and rich soil. However, with only little to preserve of this high fertality along the exterior land, not all animals could accesibly settle here. Already with less fertile land than a "typical" environment, these areas are already densely populated- leaving other animals to remain otherwhere- thus including migrants. This battle of territory (usally in triumph of the first natives to that partciular region) forced other non-native species further inland to the drier, less populace areas. This was a large influence on the animals, where non-adaptant animals would eventually either famish or dehidrate to death. As for the fertality of the Australian fuana themselves, a decent precentage of the species have remained constant, with no genetic alterations- mostly from the shortage of inhabitant species arrival. Only moderatley were the 'outsiders' able to change the Australian mutations.
SOLITARY AND IDIOSYNCRATIC WILDLIFE
The Continent of Australia soley ebraces the world's most disversified ecosytem, the greatest raging climate, and the world's most habiational adapted animals. This evolution of living has been enforced to become adjustant with their resources provided and surrounding environement. Breifly catagorized are the 3 most specific- and influental reasons clarifying the individuality of their endemic evolution. The following fators hold a detrimental ammount of signification, to the Australian native's and thier sanctuaries. This process of biodiverse evolution has been most contributed by the continent's global isolation, it's climate and environmental conditions, and the high fertality rates along the exterrior of Australia. All these components have allowed the botic wildlife of Australia to thrive and hereditary advance through out age.

Australia experiences a relatively erratic climate in comparison to other continents of the world. Rainfall has been unpredictable to some regions- supporting a land of droughts and extreme forest fires.The continent has also an appalling record of mammal extinction, from such harsh conditions.
