The history of Aboriginal Australians is thought to have spanned 40,000 to 45,000 years, although some estimates have put the figure at up to 60,000 years before European settlement. The Aboriginal Australians lived with a strong dependence with the land, and also the water. Each group developed skills for the area in which they would live – hunting or fishing or gathering. The Australian Aboriginal history changed radically after the 18th- and 19th-century settlement of the British: Indigenous people were displaced from their ways of life, were forced to submit to European rule, and were later encouraged to assimilate into Western culture. Since the 1960s, reconciliation has been the pursuit of European Australian–Aboriginal Australian relations. ==Origins== There are no clear tribes or an accepted origin of the indigenous people of Australia, although they are believed to be among the earliest human migrations out of Africa. Although they likely migrated to Australia through Southeast Asia they are not demonstrably related to any known Asian or Polynesian population. There is evidence of genetic and linguistic interchange between Australians in the far north and the Austronesian peoples of modern-day New Guinea and the islands, but this may be the result of recent trade and intermarriage.〔Diamond, J. (1997). "Guns, germs, and steel". Random House. London. pp 314–316〕 It is believed that the first human migration to Australia was achieved when this landmass formed part of the Sahul continent, connected to the island of New Guinea via a land bridge. It is also possible that people came by boat across the Timor Sea. The exact timing of the arrival of the ancestors of the Aboriginal Australians has been a matter of dispute among archaeologists. The most generally accepted date for first arrival is between 40 000–80 000 years BP. Near Penrith in New South Wales, since 1971 numerous Aboriginal stone tools were found in Cranebrook Terraces gravel sediments having dates of 45,000 to 50,000 years BP; at first when these results were new they were controversial, more recently in 1987 and 2003 dating of the same strata has revised and corroborated these dates. A 48 000 BCE date is based on a few sites in northern Australia dated using thermoluminescence. A large number of sites have been radiocarbon dated to around 38 000 BCE, leading some researchers to doubt the accuracy of the thermoluminescence technique. Radiocarbon dating is limited to a maximum age of around 40,000 years. Some estimates have been given as widely as from 30,000 to 68,000 BCE.〔(Bowler, JM et al., (20 February 2003), ''Letters: New ages for human occupation and climatic change at Lake Mungo, Australia'', Nature 421, pp. 837–840 )〕 Earlier dates are requiring new techniques such as optically stimulated luminescence (OSL) and accelerator mass spectrometry (AMS), and the evidence for an earlier date for arrival is growing. Charles Dortch has dated recent finds on Rottnest Island, Western Australia at 70,000 years BP.〔Dortch, C.E. and Hesp, P.A. 1994. "Rottnest Island artifacts and palaeosols in the context of Greater Swan Region prehistory" (Journal of the Royal Society of Western Australia 77:23–32)〕 The rock shelters at Malakunanja II (a shallow rock-shelter about 50 kilometres inland from the present coast) and of Nauwalabila I (70 kilometres further south) show evidence of used pieces of ochre – evidence for paint used by artists 60,000 years ago. Using OSL Rhys Jones has obtained a date for stone tools in these horizons dating from 53,000–60,000 years ago.〔(How old is Australian Rock Art? - Aboriginal Art Online )〕 Thermoluminescence dating of the Jinmium site in the Northern Territory suggested a date of 200,000 BCE. Although this result received wide press coverage, it is not accepted by most archaeologists. Only Africa has older physical evidence of habitation by modern humans. There is also evidence of a change in fire regimes in Australia, drawn from reef deposits in Queensland, between 70 and 100,000 years ago,〔Flannery, Tim "The Future Eaters"〕 and the integration of human genomic evidence from various parts of the world also supports a date of before 60,000 years for the arrival of Australian Aboriginal people in the continent.〔Oppenheimer, Stephen, (2004),"Out of Eden: The Peopling of the World"(Constable and Robinson; New Ed)〕〔http://()〕〔Oppenheimer, Stephen "The Real Eve: Modern Man's Journey Out of Africa"(Carroll & Graf Publishers)(ISBN 0-7867-1334-8)〕 Humans reached Tasmania approximately 40,000 years ago by migrating across a land bridge from the mainland that existed during the last ice age. After the seas rose about 12,000 years ago and covered the land bridge, the inhabitants there were isolated from the mainland until the arrival of European settlers.〔Mulvaney, J. and Kamminga, J., (1999), ''Prehistory of Australia''. Smithsonian Institution Press, Washington.〕 Short statured aboriginal tribes inhabited the rainforests of North Queensland, of which the best known group is probably the Tjapukai of the Cairns area.〔(Tindale's Catalogue of Australian Aboriginal Tribes: Tjapukai (QLD) )〕 These rainforest people, collectively referred to as Barrineans, were once considered to be a relic of an earlier wave of Negrito migration to the Australian continent,〔(''"The Extinction of the Australian Pygmies" (June 2002)'' ), Keith Windschuttle and Tim Gillin〕 but this theory no longer finds much favour.〔(Colin Groves: 'Australia for the Australians' )〕 Mungo Man, whose remains were discovered in 1974 near Lake Mungo in New South Wales, is the oldest human yet found in Australia. Although the exact age of Mungo Man is in dispute, the best consensus is that he is at least 40,000 years old. Stone tools also found at Lake Mungo have been estimated, based on stratigraphic association, to be about 50,000 years old. Since Lake Mungo is in south-eastern Australia, many archaeologists have concluded that humans must have arrived in north-west Australia at least several thousand years earlier. In 2012, the results of large-scale genotyping has indicated that Aboriginal Australians, the indigenous peoples of New Guinea and the Mamanwa, an indigenous people of the southern Philippines are closely related, having diverged from a common origin approximately 36,000 years ago. The same studies show that Aboriginal genomes consist of up to 11% Indian DNA which is uniformly spread through Northern Australia, indicating a substantial gene flow between Indian populations and Northern Australia occurred around 4,230 years ago. Changes in tool technology, food processing and the Dingo appear in the archaeological record around this time, suggesting there may have been migration from India.〔(Genome-wide data substantiate Holocene gene flow from India to Australia ) doi: 10.1073/pnas.1211927110 PNAS 14 January 2013 201211927〕〔(Aboriginal genes suggest Indian migration ) Australian Geographic 15 January 2013〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「History of Indigenous Australians」の詳細全文を読む スポンサード リンク
