Chapter 11 and 12 Flashcards
What are the physical characteristics of Homo Erectus?
Sagittal keel, but a crest
Occipital torus
Taurodontism
Lighter and thinner jaw, and less prognathic face than earlier hominids
895 –1040 cc
Prominent, projecting nose
Postcranial skeleton similar to modern human
Describe the Nariokotome boy
Discovered by Leakey team at Nariokotome, Lake Turkana - 1.6 mya
1.6 metrestall, 11-12 year old
Provides evidence of prolonged development in Homo erectus
Illeret footprints
Homo Erectus, Kenya
looks human. species moved essentially like we do.
feet are arched + big toe in line w/ other toes
Homo Erectus in Middle Pleistocene
Daka, Ethiopia, More Asian Morphology, Like Peking Man -one species
Bodo Ethiopia - cutmarks on skull (defleshing)
Describe Homo erectus in Dmanisi, Republic of Georgia
5 skulls, considerable variation = showing there may be less actual species than we say there are
500-600 cc
Range of habilis + erectus
Long leg
Fire!
Extends daylight, work on tools
Warmth + light, able to move to cold places
Keeps people together = social centre, dev. language, complex social relationships
Cooking food = more nutrients, bigger brains
Describe H Erectus in Asia
Zhoukoudian - Peking Man (H Erectus fossil).
Davidson Black, Canadian physician/paleontologist
Took over: Franz Weidenreich, German
40 individuals, proof that we lived in caves. - stone tools and controlled fire
Describe hand axes
Acheulian hand axes, Europe and Asia. Look like a pointy tear drop.
Describe Homo erectus Culture
Tool use ~1.5mya
Big Game Eating - evidence large scale fauna remains (e.g. Torralba + Abronan Spain)
Unclear hunt or scavenge sites
Evidence for control of fire in South Africa ~1.4 mya + China ~.5 mya
What are H. Erectus sites like?
Close to water sources + food resources
Some camp sites in caves, most are open-air sites (Terra Amata, France)
They may have been building things? (The hut?)
Language and H. Erectus
Endocasts suggest hemispheric specialization
Some suggest H erectus has ability to possess linguistic skills to the level of a modern 6 yo
Archaic H. Sapiens
transition ~500,000 yrs ago
Begins S. + East Africa
Homogeneity in H Erectus specimens geographically + temporally ~1 million years
Some reduction in teeth + face size, small increase in cc over this period
Early forms called H Heidelbergensis
What was found in the Petralona Cave in Greece?
Skeleton and a skull of a past hominin
Archaic H. Sapiens in Africa
Large face w/ browridge
Large, heavily worn front teeth
Near modern brain size
Bodo (Ethiopia), 600,000 yrs old, Brain 1,250 cc
Kabwe (Zambia), ~250,000 years old, 1,300 cc
Archaic H. Sapiens in East Asia
long + low braincases
brain size close to or within modern human range
Have massive browridges
Same kinds of morphology as African archaic H. sapien skulls
implies gene flow connecting these pop. across continents.
Indonesia, India, China
