Australian archaeology is a large sub-field in the discipline of archaeology. Archaeology in Australia takes three main forms, Aboriginal archaeology (the archaeology of Aboriginal and Torres Strait Islander people in Australia before and after European settlement), historical archaeology (the archaeology of Australia after European settlement) and maritime archaeology. Bridging these sub-disciplines is the important concept of cultural heritage management which encompasses Aboriginal and Torres Strait Islander sites, historical sites and maritime sites. ==Research and investigations== Archaeological studies or investigations of Aboriginal and Torres Strait Islander people and culture in Australia have had many different agendas through time. Initial archaeological investigation was often focused on finding the oldest sites. By the 1970s, archaeological research was concerned with the environment and the way it impacted on humans. In the late 1970s cultural heritage management gained prominence, with the increasing demands by Australian Aboriginal and Torres Strait Islander groups for representation in archaeological research. At a research level the focus shifted to cultural change of Australian Aboriginal and Torres Strait Islander people through time. Currently, archaeological research places great importance on Australian Aboriginal and Torres Strait Islander people's viewpoints on the land and history of Australia. Consideration is given to Australian Aboriginal and Torres Strait Islander people's belief that archaeological sites are not just capsules of the past but a continuation from the past to the present. Therefore, at a research level significance is placed on the past but also on the importance of the present. The first settlement of Australia is a popular research topic both in archaeology and in the public arena. There is consensus that no human or closely related species evolved independently in Australia. This is because there have been no species of primate found in Australia, either in the present or in the fossil record. It is therefore assumed that the first settlers of Australia came from outside. At present the fossil record suggests that the first settlers were ''Homo sapiens'', or fully modern humans. There is controversy over where the first Australian Aboriginal and Torres Strait Islander people originated. Both of the two main theories postulate that the first settlers were fully modern humans. Asian genetic studies have demonstrated that there are similarities between Australian Aboriginal and Torres Strait Islander people, Melanesians and Indians. However, the suggested date of 60,000 years ago for initial settlement is quite early when compared to other areas of the world. This may suggest that the Australian Aboriginal and Torres Strait Islander population derive from an early African population which migrated along the south coast of Asia, at a much faster rate than other populations migrating across the continents of the Holocene. The first settlement of Australia most likely occurred during the last glacial maximum. During this time Australia and New Guinea were joined as a single land mass called Sahul. The south-east Asian continent and islands were also joined as a single land mass called Sunda. It is theorised that the first Australians crossed the sea between Sahul and Sunda about 60,000 to 40,000 years ago. Other dates have been suggested, and this timeframe is not seen as conclusive. Sunda and Sahul had a permanent water-crossing, meaning that the first Australian Aboriginal and Torres Strait Islander people had to make a crossing on the open sea (see Wallace Line). Sahul is important in that in the past Australia was not an isolated continent, but was joined with New Guinea (and Tasmania). As such, New Guinea has also been the focus of archaeological investigations by Australian researchers. The most important early sites in Australia are: * Rottnest Island (70,000 years old) * Nauwalabila (55,000 – 60,000 years old) * Malakanunja (45,000 – 61,000 years old) * Devil's Lair (45,000 years old) * Lake Mungo (61,000 or 40,000 years old) – controversy exists over precise dating (see below) The change in sea levels means that the first settlements located on the coast would have been submerged. With the settlement of Australia, it is most probable that Australian Aboriginal and Torres Strait Islander people first settled on the northern coast, as this is the area closest to Asia. However, the actual spread of people and the settlement of the continent is debated, with three major models put forward: * Concentric dispersal through the entire continent through one single "entry" point. * Coastal dispersal by spreading along the coastline and later entering inland areas, mainly via the major waterways. * Fluctuating colonisation in and out of different environmental zones. For example, in plentiful years the population would occupy semi-arid regions, but in drought would move to areas with better resources. 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「Australian archaeology」の詳細全文を読む スポンサード リンク
