The Dragon-Man Skull from China Rewrites Humanity’s Family Tree
An ancient skull from central China is rewriting humanity’s origin story. Yunxian 2 is about a million years old and was long labeled Homo erectus. A new Science study used computer tomography to digitally reconstruct the skull, revealing a high brain volume and a long, low forehead. Those features align Yunxian 2 with Homo longi (Dragon Man) and with Denisovans, suggesting Asia was a crossroads in early human evolution and that Neanderthals and our own lineage diverged in a remarkably short window.

A Century-Old Mystery Rebuilt: From Yunxian 2’s Deformation to a Digital Revival
Discovered in 1990 at the Yunxian site in central China, the skull bore heavy deformation that hampered study. For decades it was classified as Homo erectus. Modern CT-based methods allowed scientists to digitally 'reassemble' the skull, yielding a clearer portrait of Yunxian 2 and its place in the early Homo tree. The reconstruction highlights how far paleontology has come from the era of rough classifications.
A Face That Mirrors a Deep Past: Brain Size and the Dragon-Man Link
The reconstructed skull shows a relatively large brain and a long, low forehead—a combination that links Yunxian 2 with Homo longi (Dragon Man) and with Denisovans. As co-author Chris Stringer notes, “The Homo longi branch, to which the Denisovans belong, persisted for more than a million years. But the same happened with Neanderthals and our direct ancestors.”
A New Timeline for Early Humans: Rapid Diversification
Analyzing 57 ancient skulls, the researchers built a revised timescale. Around 1.38 million years ago, the Neanderthal lineage split from the common trunk. About 1.2 million years ago, the Dragon Man–Denisovan branch diverged. Finally, around 1.02 million years ago, Homo sapiens began its own path. The short 360,000-year window between these splits suggests an extraordinarily rapid diversification of human groups in the ancient world.
Asia at the Heart of Our Deep History: Implications for Our Roots
Yunxian 2 likely represents an early form of the group that later gave rise to the Denisovans. The study emphasizes Asia as a central hub of human evolution, pushing our roots deeper into the past and revealing a complex, dynamic history where Neanderthals, Denisovans, and Homo sapiens emerged in close succession. The origins of humanity are more tangled—and more ancient—than we once imagined, with Asia at the center.
