History & animals of Australia

HISTORY The first human habitation begun about 42,000 to 50,000 years ago – (Nowadays they are called Aborigines). The indigenous Australians (Aborigines) were hunters and gatherers. The Aborigines population was estimated at 350,000 at the time of European settlement. By 1788, the population existed as 250 individual nations,

Aborigines were amongst the oldest, most sustainable and most isolated cultures on Earth prior to European settlement beginning in 1788. The greatest population density was to be found in the southern and eastern regions of the continent

The written history of Australia began in 1606 (Willem Janszoon is credited with the first authenticated European discovery of Australia). On 19 april 1770, HMS Endeavour sighted the eastern coastline of Australia.( James Cook sailed along and mapped the east coast of Australia, which he named New South Wales and claimed for Great Britain).

ANIMALS The geologic and climate is like it is because Australia was once a part of the southern supercontinent Gondwana, which also included South America, Africa, India and Antarctica. Both geologic and climate events helped to make Australia’s fauna unique. The establishment and evolution of the present-day fauna was apparently shaped by the unique climate and the geology of the continent.

The fauna of Australia consists of a huge variety of strange and unique animals; some 83% of mammals, 89% of reptiles, 90% of fish and insects and 93% of amphibians that inhabit the continent are endemic to Australia . A unique feature of Australia's fauna is the relative scarcity of native placental mammals. Uniquely, Australia has more venomous than non-venomous species of snakes.

MAMMALS Australian fauna consists 89% of mammals. Australia has a rich mammalian fossil history, as well as a variety of extant mammalian species, dominated by the marsupials. Although marsupials and placental mammals did coexist in Australia in the Eocene, only marsupials have survived to the present. Some Mammals:

The extincted Tasmanian tiger

Numbat

BIRDS Australia and its territories are home to over 800 species of bird. Australian parrots comprise a sixth of the world’s parrots, including many cockatoos and galahs. About 200 species of seabird live on the Australian coast, including many species of migratory seabird. Some Birds:

Sharks inhabit all the coastal waters and estuarine habitats of Australia’s coast. There are 166 species. Several exotic freshwater fish species Several exotic freshwater fish species. Some fish :

The Murray Cod is the largest wholly freshwater fish.

The spotted wobbegon is the largest wobbegong shark, reaching a lenght of 3,2m.

Invertebrates Of the estimated 200,000 animal species in Australia, about 96% are invertebrates. Australia has a wide variety of arachnids, including 135 species of spider that are familiar enough to have common names. There are many unique marine crustaceans in Australian waters. Examples:
