PERTH, AUSTRALIA—The Guardian reports that a remote cave on Barrow Island, located off the coast of northwestern Australia, has yielded evidence of human occupation, including charcoal, marine and land animal remains, and other artifacts dating back to more than 50,000 years ago. Researchers from the University of Western Australia, the University of Queensland, the University of Adelaide, the University of Waikato, and Oxford University say the cave served as a hunting shelter between 50,000 and 30,000 years ago, and then became a dwelling for groups of families after about 10,000 years ago. The cave was then abandoned around 7,000 years ago, when the island is thought to have been separated from mainland Australia by rising sea levels.
