Yunxian skulls from China are nearly 1 million years old. Skulls previously called Homo erectus are actually early Homo longi or Denisovans. Digital reconstruction shows faces match Dragon Man, a Denisovan candidate. Denisovans split from sapiens lineage over 1 million years ago. This pushes sapiens origin back 400,000+ years earlier than thought. Five large-brained human groups trace ancestry over 1 million years old. Denisovans are closest extinct humans to sapiens. Split between sapiens and Neanderthal-Denisovan lineages at least 500,000 years earlier than prior estimates. Conventional Out-of-Africa timeline challenged by ancient Asian fossils. Sapiens lineage possibly emerged in Eurasia before migrating to Africa. Million-year-old proto-sapiens fossils likely undiscovered or unrecognized. Yunxian fossils reshape human evolution timeline. Neanderthals and Denisovans diverged earlier from common ancestor. Asian Homo erectus separate from these lineages. Heidelbergensis also traces back over 1 million years.
