The first humans arrived in Australia up to 15,000 years earlier than previously thought, scientists have announced. During excavations of the Madjedbebe rock shelter in northern Australia, researchers have found thousands of artefacts, including stone tools, grinding stones and hatchets, showing humans must have been at the site at least 65,000 years ago. The findings, published in Nature, have major implications for our understanding of early human migration beyond Asia, why Australia’s megafauna went extinct, and, potentially, if these early humans interacted with Homo floresiensis, the mystery “hobbit-like” species found only on the Indonesian island of Flores.
