A digitally reconstructed skull found in Hubei Province in 1990, dubbed Yunxian 2, belongs to a sister line of Denisovans rather than Homo erectus. New analysis pushes back the split of human lineages by hundreds of thousands of years and links the specimen to the ‘Dragon Man’ find. Researchers say this reshapes the timeline for Homo sapiens, Neanderthals and Denisovans. The study, published in Science, could force textbooks to rewrite human origins. It offers a fresh piece in the puzzle of how ancient humans spread across Asia.
