Scientists have uncovered a nearly complete ancient skull in China that sheds light on the Denisovans, a mysterious group of archaic humans known primarily through DNA evidence. The skull, often referred to as the 'Dragon Man,' provides new insights into the physical appearance and braincase of this Stone Age population that once interbred with modern humans. The fossil, estimated to be around 140,000 years old, was found in Harbin, China, and has helped confirm the species identity through protein analysis. This discovery may clarify the relationship between Denisovans and other ancient human species, including Homo erectus and Neanderthals, potentially identifying a lost branch of the human evolutionary tree. The findings contribute to a deeper understanding of human ancestry in Asia and address longstanding mysteries about extinct human relatives.
