Overview
Based on a massive, well-preserved cranium from Harbin, northeastern China, with a brain capacity of approximately 1420 cc. The skull combines a very large brain with ancestral features including a large brow ridge and wide face. Phylogenetic analysis by the describers placed it closer to H. sapiens than to Neanderthals. Some researchers argue the Harbin skull may actually represent a Denisovan, which would finally put a face to that genetically defined group.
