A discovery in China has shed new light on human history, with findings suggesting interbreeding between Homo sapiens and other ancient human relatives. The discovery involves fossils, including teeth and a skull, that are estimated to be hundreds of thousands or even millions of years old. The exact implications of the find are still being reported, with some outlets suggesting it rewrites the origins of modern humans, while others mention connections to Neanderthals, Denisovans, and Homo erectus.
