1-million-year-old skull suggests Homo sapiens divergence pushed back 500,000 years.

Yunxian 2 skull from China (discovered in 1990) got a digital makeover in 2025. CT scanning reveals a 1-million-year-old brain case as large as ours. If this Homo longi relative had modern-sized brains, our species may have split off much earlier than thought.

Key Facts

  • Yunxian (Meipu) 2 skull discovered in China in 1992, heavily crushed and distorted
  • In 2025, researchers applied CT scanning and digital reconstruction techniques to restore the skull
  • The individual lived around 1 million years ago
  • Reconstructed brain case is large, roughly the same size as modern humans
  • Skull anatomy suggests it belongs to Homo longi lineage, a sister species to Denisovans
  • If Yunxian (Meipu) 2 is a Denisovan-like lineage with large brain at 1 million years ago, Homo sapiens must have diverged earlier than previously thought
  • Paleonthropoligist Chris Stringer suggests million-year-old Homo sapiens fossils likely exist but haven't been found yet
