The remains of one of the earliest modern humans to inhabit eastern Asia have been unearthed in a cave in China.
The find could shed light on how our ancestors colonised the East, a movement that is only poorly understood by anthropologists.
Researchers found 34 bone fragments belonging to a single individual at the Tianyuan Cave, near Beijing.
Details of the discovery appear in Proceedings of the National Academy of Sciences journal.
Radiocarbon dates, obtained directly from the bones, show the person lived between 42,000 and 39,000 years ago.
"For this time period, which is critical for understanding the spread of modern humans around the world, we have two well-dated human fossils from eastern Asia," said co-author Professor Erik Trinkaus, from Washington University in St Louis, US.
"We have remains from the Niah Cave from Sarawak on Borneo, and now this specimen from China. As you go west, the next specimens are from Lebanon. There's nothing in between."
