Document Summary

Lecture 12a: archaic & modern homo sapiens: early archaic: h. heidelbergensis, late archaic: h. neanderthalensis. 1250cc skulls are larger and more gracile than in erectus. European specimens have larger nasal bones & nasal apertures (openings) *several forms of fossil hominids that have a combination of archaic-derived traits in their skulls. *more efficient at making tools than h. erectus. *may have been the first hominid to build shelters, inferring from the environment. *homo heidelbergensis is likely the immediate common ancestor for two species: *some traits are similar to heidelbergensis, but some traits are derived and unique to them, mostly reflecting adaptations to cold climates. *primitive features: prominent brow ridge & nasal bone, wide nasal aperture, mid-facial prognathism. *derived features: upright (but low) forehead, occipital bun, large infraorbital foramina. *large nasal aperture- helps moisten the cold, dry air. *large infraorbital foramina, help deliver greater blood flow to the face.
