Anthro Test 3 Flashcards
Paleoanthropology
the study of ancient humans
Paleolithic
Old Stone Age”, 3MYA- 14 KYA, lithic = stone
Cultural adaptation/ Biological adaptation
Climate change caused hominins to adapt
Environment: 8-5 MYA, global climate changes, cooling and drying, daytime temp= warm to hot, nights= cool or cold, dense forest declined patches of trees + grassland

Boxed Article: Chemical Analyses of Bones and Teeth
- Physical anthropologists and archaeologists study ancient diets in several ways, most of them indirectly.
- Chemical analyses of bones and teeth, the most common remains found in excavations, can reveal distinctive traces of the foods that metabolically went into the bones and teeth
- ratio of strontium to calcium in bone: relative amounts of plant and animal in the diet
- carbon isotope ratios: can tell us what types of plants people were eating ex: trees, shrubs, and temp zone grasses
- People in China were relying heavily on cereal
- non chemical analyses of teeth and bones were used to study difference between people in different geographic regions
Boxed Article: Migrants and Immigrants
- homo erectus was supposed to be the first to leave Africa
- but recent evidence suggests that it was actually the homo habilis followed by the homo erectus
- homo erectus migrated the far and fast
Boxed Article: Facial Reconstruction
- facial reconstruction is based on knowledge of the skull musculature and the thickness of soft tissue, determined over many years
- forensic anthropologists have established a standard set of 21 to 34 locations on the skull where the average soft tissue thickness are known
- first step is mark on skull and put clay on it
- the size and shape of the nose are reconstructed based on the size and shape of nasal opening
- size and shape of lips are harder to determine
- artistic
Boxed Article: Mother Infant Communication
- hunters communicate with hand signals rather than speech during hunts
- hunting and tool making are typically male roles
- language may have developed through mother-infant communication
- problems faced by hominid mothers and infants may have also played a big role in language
- infants communicate distress and desire to mothers
- language may have begun to develop before toolmaking hunting
Boxed Article: Depiction of Women in Upper Paleolithic Art
- most depictions of women show them in some motherhood role- pregnant, in childbirth, or carrying an infant (and perhaps walking with older children)
- “womanhood” rather than “motherhood”
Boxed Article: The Archaeology of Environmental Collapse
- “Those who cannot remember the past are condemned to repeat it.”
- archeologists developed a program called ARCHAEOMEDES project for the EU with the expressed purpose of developing a long term perspective on the problem of land degradation
- Rhone Valley triggered land degradation because the infrastructure could only be sustained during good times
Neolithic Revolution
- Domestication of plants and animals
- food collectors become food producers
- Population increases
- Humans go from being an insignificant form of life on this planet to a major one
Jared Diamond
- Worst mistake in the history of the human race- a revisionist theory
- People actually less healthy after Neolithic/ have a less varied and healthy diet
- Smaller bodies
- More diseases
- More food shortages/ If 80% of your diet is rice what happens if the rice crop fails?
Characteristic of civilization
- Urbanization
- Writing systems
- Metallurgy – bronze. Copper, gold
- State society
- A society does not have to have all these things to be classified as civilized but it has to have some of them.*
Upper Paleolithic Tools
1) The more recent the tool kit, the higher the standard of the workmanship
2) The number of different items in the tool kit increases.
3) Increased specialization
4) The mode of manufacture exhibits more efficient use of raw materials.
Evolutionary Discordance Hypothesis
As you evolve things aren't as a big deal as they once were. Examples: -Sweet tooth -Obesity -Periods -Repetitive stress injuries
