There are two traits in Homo heidlebergensis that foreshadows the evolution of Neandertals. What are they? Both of these skulls are Homo heidelbergensis: Trait 1 is missing, broken teeth, and Trait 2 is a big ear hole. Trait 1 is midfacial prognathism (which includes inflated nasal bones)) and Trait 2 is an occipital torus that is close to becoming a bun. Both of the above are false. .
