Describe h. heidelbergensis:
- Increased cranial capacity - 1200cc.
- Supraorbital torus is divided.
- Broad frontal bone, expaned parietal walls.
- Wooden spears, acheulian biface tech.
- Common ancestor of modern humans in Africa and Neanderthals in Europe.
Mauer, Petralona, Arago, Atapuerca
- Dentition resembles ergaster.
- Premolars have 3 roots, not 1.
- Mandible similar to heidelberg.
- Modern face, primitive dentition.
- Oldowan tools.
- ~800kya in Spain - La Gran Dolina. Earliest European group.
- Strong evidence of nutritional cannibalism.
- Atapuerca, Gran Dolina.
- East Africa.
What is associated with these sites?
- Atapuerca - h. heidelbergensis. The pit of bones - the largest collection of pre-modern hominid fossils in the world.
- Petralona - Site in Greece. Skull with early Neanderthal characteristics.
- Africa - Heidelbergensis 500k-100kya. More obviously similar to modern h. sapiens.
Phylogenic implications of accepting H antecessor as a species?
- Instead of heidelberg being an ancestor of modern humans, accepting antecessor as a species/ancestor would place both erectus and heidelberg off the direct line.
- Ergaster -> erectus.
- Ergaster -> antecessor -> sapiens.
- Antecessor -> heidelberg -> neanderthal.
