The study also finds that the population was devastated during the latest Ice Age, but later rebounded.The prehistoric settlement of Australia has long been considered a simple story: a founding group of 150 people or fewer made it to the Australian mainland 50 millennia ago and grew to no more than 1.2 million by the time European settlers arrived in 1788.Applying methods that others had developed to analyse a similar dataset from North American artifacts, Williams graphed the number of data points for each 200-year period, and made the assumption that for each given area, changes in the number of data points from one period to the next were a good indication of changes in population size — while correcting for the fact that some types of archaeological site can be lost over time owing to processes such as erosion.Assuming that the population would be between 750,000 and 1.2 million by the eighteenth century, he fit a smooth population curve to the data.For the best commenting experience, please login or register as a user and agree to our Community Guidelines.You will be re-directed back to this page where you will see comments updating in real-time and have the ability to recommend comments to other users.For example, Williams' work shows more data points in the eastern half of Australia than in the west, not because more prehistoric peoples necessarily lived there, but because most of the country’s archaeologists live and work in the east.
At least 1,000 Aboriginal founders first arrived in Australia some 50,000 years ago, a reconstruction indicates — numbers that could be evidence of an intentional migration rather than the accidental stranding of a few individuals at a time.“This is the first time an actual evidentiary data set has been used to construct continent-wide pre-European demographics, which is a significant step forward,” says Sean Ulm, an archaeologist and director of the Tropical Archaeology Research Laboratory at James Cook University in Cairns, Australia. “Using radiocarbon dates to reflect levels of human activity is not a method well-substantiated among archaeologists,” says Peter White, an archaeologist at the University of Sydney in Australia and editor of Archaeology in Oceania.The quantity and locations of radiocarbon dates measured by researchers at archaeological sites has little to do with past human activity, he says.I had already tried to discover the secret of visual attraction in my article to look better.
