Scientists digitally reconstructed the squashed skull, thought to be 1 million years old, and its features suggest that the fossil belonged to the same lineage as a striking specimen called “Dragon Man” and the Denisovans — an enigmatic and recently discovered population of prehistoric humans with murky origins. The skull’s age and categorization as an early Denisovan ancestor would mean the group originated much earlier than thought.
The researchers’ wider analysis, based on the reconstruction and more than 100 other skull fossils, has also sketched a radically different picture of human evolution, they reported Thursday in the journal Science.
