Aborigines are indigenous peoples who migrated to Australia and many of the islands in Oceania. There are currently about 517,000 Aborigines in Australia, throughout the country. The term “aboriginal” is used as a collective term for the various indigenous groups, usually in Australia. Aborigines are not Negroes of African origin.
The word “Aboriginal,” arrived from the Latin phrase “ab origine,” meaning "from the beginning". Aborigines probably came to Australia from Southeast Asia for about 40 000-60 000 years ago, and is therefore one of the oldest indigenous groups. They must have come by sea, probably with fleets, since the continent in all of human history has been separated from Asia by at least 60 km long, open ocean seas. Modern research in mitochondrial DNA have revealed that Aboriginals are not closely related with people from Polynesia, but rather closely related to people in Melanesia. Based on evidence from DNA research. It has also been speculated that they may be related to certain ethnic groups in India.
Mats:
In the course of a few thousand years all species with body weight greater than humans, with the exception of saline crocodile eradicated because of the aboriginals hunting them down. Of the surviving animal species survived only the smaller individuals, so that current forms are considerably smaller than they were before Aboriginal immigration. They sat fire to the vegetation to hunt smaller animals, this affected the plant life significantly. The post- colonization population grew, but Aborigines remained hunter-gatherers and never developed any form of agriculture. Australia's nature has not plant species suitable for domestication and nature has not high enough production to provide for the necessary population density.
Matias: Population density was therefore relatively low when James Cook and his crew landed on the Australian continent in 1770. Initially used the "white man"
