Million-Year-Old China Skull Challenges Human Evolution Timeline
Digital reconstruction of a 1-million-year-old skull suggests Homo sapiens diverged 400,000 years earlier than thought and challenges Africa-centered origin theories, researchers say.
- At the Orozmani excavation near Tbilisi, teams uncovered a jawbone representing the oldest early human remains yet found outside Africa, along with animal fossils and stone tools illuminating Eurasia's first colonisers.
- Using CT scanning and 3D modelling, the Shanxi University research team led by Xiaobo Feng restored the distorted Yunxian 2 skull, reassigning it to the Homo longi clade.
- Comparative analysis shows Yunxian 2 possesses traits linking it to Homo longi and Homo sapiens, as comparisons with 26 most complete hominin fossils indicate a close relationship to Asian Homo longi forms.
- Researchers argue the finding implies a far longer period when Homo sapiens, Neanderthals, and Homo longi coexisted for around 800,000 years, with Homo sapiens emerging at least 500,000 years earlier.
- In peer review and comment, scientists noted that timing estimates remain uncertain within 100,000 years, and experts urge caution, saying conclusions are plausible but far from certain.

According to the investigation, there may have been various hominids, including Neanderthals and Homo sapiens, much earlier.
The digital reconstruction of a fossil skull calls into question the knowledge of human evolution. According to this, Homo sapiens lived near hominids far earlier than thought: in Asia instead of Africa.
A skull reconstruction indicates an earlier separation of homo sapiens – and an origin in East Asia.
The digital reconstruction of a million-year-old skull suggests that humans may have diverged from their ancestors 400,000 years earlier than previously thought. Moreover, according to a study in Science, this occurred in Asia, not Africa. The crushed skull was discovered in China in 1990 and named Yunxian. Until now, it was considered to belong to Homo erectus, an ancestor of our species.
Digital analysis of bone remains known as Yunxian 2 in China shows that the separation between Homo sapiens, Neanderthals and Denisovans occurred long before the estimate
