Since their discovery a century ago, hundreds of naturally preserved mummies found in China’s Tarim Basin have been a mystery to archaeologists. Some thought the Bronze Age remains were from migrants from thousands of kilometres to the west, who had brought farming practices to the area. But now, a genomic analysis suggests they were indigenous people who may have adopted agricultural methods from neighbouring groups.
As they report today in Nature1, researchers have traced the ancestry of these early Chinese farmers to Stone Age hunter-gatherers who lived in Asia some 9,000 years ago. They seem to have been genetically isolated, but despite this had learnt to raise livestock and grow grains in the same way as other groups.
A life size kangaroo painted in red ochre around 17,300 years ago is Australia’s oldest known rock art. This indicates that the earliest style of rock art in Australia focused on animals, similar to the early cave art found in Indonesia and Europe.
Thousands of rock art sites are found all over Australia, with the Kimberley region of Western Australia containing a particularly rich record. But dating the images is challenging as the minerals and organic material needed to determine when the art was created are hard to find.Read More »
