1. Evolution: Based on work of Darwin, fossil record, genetics…
2. Creationism (link to Intelligent Design): Based on Genesis, other creation myths/legends…
3. Other, less supported theories include Chariot of the Gods…
Intro: Theory
Scientists: Paleontologists, archaeologists, anthropologists
Study fossils, artifacts…Dating techniques:
C14, K-Ar, U238 (absolute)Strata, tree rings, techniques/materials (relative)
A. Interpreting evidencei. Darwin’s Origin of Species: natural selection
ii. Early hominid finds in Java, Beijing… Leakeys found australopithecines in E. Africa
iii. Evidence & other species help scientists trace evolution of humans back over 4 million years
I. African Genesis
B. Human evolutioni. Hominids: distinguished by bipedalism,
large brain, larynx locationii. Had advantage during climate changes
of Great Ice Age/Pleistocene. Did climate trigger evolution?
iii. Possible “tree”:AustralopithecinesHomo habilis (Handy, tool-using man)H. erectus (Walks upright man) H. sapiens (Thinking man) ~400,000 –
100,000 years ago; Neanderthals (?), Cro-Magnons
New discoveries still filling out record – recently, “Hobbits” in Indonesia, gene studies and new finds and analysis by the Leakeys are revising timelines.
And new discoveries are continually being made…Older fossils Tools and artifacts in older layersGenetic evidence that modern humans may
carry some Neanderthal genes…“Hobbits,” Denisovans and “X-woman” may
have been concurrent with modern humans as well…
C. Migrations i. Ice Age allowed H. erectus & H. sapiens to migrate to Europe & Asia. Sapiens crossed land bridge to Americas ~ 32,000 – 13,000 years ago; also crossed to Japan, New Guinea…
ii. Minor physical evolution… skin pigmentation? Most adaptation cultural.
A. Food Gathering/Stone Technologyi. Stone Age: ~2 million yrs ago to 4000 yrs ago.
ii. Paleolithic (Old Stone Age): Scavenging & hunting. Neolithic (New Stone Age): Beginnings of crop cultivation.
iii. Diet: Foraged vegetables, some meat. Use, control of fire ~ 1 – 1.5 mya. Cooking pots 12,500 ya.
II. Ice Age History/Culture
B. Gender Division/Social Lifei. 2-parent families (slow infant maturation)
ii. Probably: women gather, cook, child care; men hunt. Small migratory groups.
C. Hearths/Cultural Expressionsi. Migratory camps. Animal-skin clothing.
ii. ~ 3-5 hrs./day for food/clothing/shelter. Time for culture: gathering, organizing, & passing on info, art, & religion.
iii. Neanderthal burials & Cro-Magnon cave art suggest complex religion/belief in afterlife. (Could cave art be older than we think?)
A. Transition to plant cultivation (Neolithic period)i. Ag Revs – domestication of plants
and animals – occurred independently in different regions. Climate, available wild plants & animals a factor.
ii. Semicultivation… then fire & specialized tools.
iii. Best documented in Middle East; also in E. Sahara, Nile Valley, Greece, central Europe. Swidden agriculture: change fields as fertility depletes.
iv. Environment dictated crops. Ex.: wheat/barley in Med., sorghum/yams in Africa; rice in E/S Asia, maize/potatoes in Americas.
III. Agricultural Revolutions
B. Animal domestication/Pastoralismi. Occurred along w/ plants. Dogs 1st, then sheep/goats.
ii. Environmental link (animals w/ agriculture) – plow labor, fertilizer…
iii. Exceptions: Americas only had llamas, guinea pigs, & fowl, so hunting & human labor continued. Arid C. Asia & Africa supported pastoralists.
C. Agricultural & Ecological CrisisTransition occurred because of global warming of Holocene ~9000 BCE changed environment & wild plant/animal availability. Ag revs caused increase in human population: 5000 BCE, 10 million; 1000 BCE, 50-100 million. Health?
A. Rural population & settlement i. Food production negatives: more work, (initially) diet less nutritious. Positives: reliable sources of food, surpluses can be stored
ii. Surpluses gave advantage: . . . greater pop. growth & displacement of gatherers in Europe (genetics studies)
iii. Kinship groups, maybe matrilineal (?). No hard evidence for patrilineal/matrilineal or matriarchies.
IV. Life in Neolithic Communities
B. Cultural Expressions i. Worship of ancestral & nature spirits. Reflected in Hindu texts.
ii. Megaliths for burial chambers, calendar circles, observatories (ex: Stonehenge).
iii. Expansion of societies reflected by patterns of language group distribution.
C. Early Towns & Specialists i. Mostly villages; some areas had resources for towns & elaborate dwellings, food storage, craftsmen. Ex: Jericho, on Jordan River; Catal Huyuk.
ii. Catal Huyuk, in Anatolia, ~ 7000-5000 BCE. Obsidian trade. Many crafts. No evidence of dominant class or centralized political leadership.
iii. Art shows hunting. Agriculture mainstay of economy. Flourishing religion w/ offerings of food. Goddess worship/priestesses.
iv. Copper, lead, silver, & gold decorative/ceremonial objects. Stone tools/weapons.
v. Towns indicate emergence of social organization: food producers support non-producing specialists (priests, craftsmen) & provide labor for projects like walls, megaliths, & tombs. Free or coerced?
