Dating the first australians
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.
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.
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: There is significant debate over the date of arrival of Aboriginal and Torres Strait Islander people into the Australian continent.
Currently, archaeological research places great importance on Australian Aboriginal and Torres Strait Islander people's viewpoints on the land and history of Australia.
The first settlement of Australia is a popular research topic both in archaeology and in the public arena.Until the 1950s it was often believed that arrival of the first Aboriginal people was within the last 10,000 years.In the 1950s, the dates were extended to the last Ice Age, based upon falling sea-levels at that period and the existence of landbridges linking the islands of the Sunda Shelf and the Sahul Continental Shelf with Australia, New Guinea and Tasmania.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.
This limitation has prompted many archaeologists, including Rhys Jones and Alan Thorne, to include thermoluminescence dating methods in their studies of early occupation sites.
