Archaeology and World Prehistory Final Flashcards
(78 cards)
Archaeological survey
Step 2 of excavation/research process
Might include remote sensing, “ground truthing”, (visiting sites), systematic foot survey
Anthropocene
the geological period in which humans began to permanently alter the environment. The beginning of the Anthropocene is a turning point
What did Agriculture cause?
There’s a general decline in animal foods, which means loss in B12, A & D
* Important minerals iron & zinc
* Animal fat is scarce but an important nutrient
Quality of plant foods declines in many areas
* 3rd choice foods become staples
* Lots of calories
* Poor sources of protein, vitamins, & minerals compared to hunter-gatherer diet
How did Agriculture affect food?
Food become softer with transition to agriculture
Excess intake of fat (obesity)
* Adult-onset diabetes
* Atherosclerosis (cholesterol)
* Coronary heart disease
* loss of animal fats related to fatty domestic animals (not leaner wild animals)
* Wild African animals – 4% body fat
* Domestic animals (grain fed) – 25-30% body fat
* High blood pressure
* Range of cancers
What were the common problems with agriculture production?
Instability, crop failure, nutrient loss, damage to ecological niche
* Common problems especially in overly intensive agricultural systems
* Intensification is the only option when faced with declining yields
* Intensification is a process whereby farmers increase their labor input,
improve technologies, narrow a crop base, expand farming area, or use land more frequently
* Goal is to increase yield to maintain food production needs for population
Anthropogenic environments
Human-caused and human-related change in environments
Humans emerged in the prior period before Pleistocene
Moving forward we see even greater cultural diversity and expression among humans worldwide
Mobile hunter-gatherers
* Small groups
* Most of daily activities happened outside
* Open-air sites/rock shelter overhangs
* Flexibility and symbolic thought/culture both led to success of humans
Excavation
Step 3 in excavation/research process
There’s a site grid created, then take samples through auger holes, block and trench excavations and dig through the sub soil
Afterwards, mapping units and each section
Overkill Hypothesis
Argues that human activity principally led to the extinction of megafauna shortly after the Ice Age ended
Niche construction
How humans or a species change their habitat in a way that works best for them and improves its fitness to last for them and their descendants
Genetics are transferred + cultural practices
Chemically alters the environment, rock sediments, atmosphere, oceans, pollution, extinctions, extracting resources, domestication of animals
Stratigraphy
Identifying and analyzing the geological layers and records that indicate the significant impact of human activity on the Earth system
Rapa Nui Mo’ai
The Rapa Nui people, on Easter Island, by carving and erecting these massive statues, significantly altered their environment and created a unique cultural landscape.
Norse Greenland
The Norse settlers, who had thrived in Greenland during the Medieval Warm Period (around 950-300 AD), faced increasing challenges as the climate shifted. They had to face, reduced agricultural productivity, more difficult sea conditions, and changes in food availability. The Norse Greenlandic society appears to have struggled, leading to its eventual decline and abandonment.
Context
Associating an artifact with the physicality of another rock, sediment, or other artifacts which is told through information such as its use, location and time, soil type, site type, the stratigraphic layer, which tells its function, significance in the chronological order
Loss of context = loss of interpretation
In situ
the location of an object that was discarded, then to be in an undisturbed deposit
It was found as it was where it was thrown away
Lascaux and Grotte Chauvet
Wall drawings at Lascaux are a dramatic example of material culture that offers us clues about ancient human behavior
Is animal, a shaman, a mythical being, or a vision of a hallucination?
What are its meaning, are you gazing at the disguised, bearded face of a Paleolithic man now dead for two hundred centuries?
Grotte Chauvet: On the walls, humans used the cave, they incised images, such as mammoth, on top of where cave bears and left claw marks, and vice versa
Artifact
Material culture
An object that’s been modified in some way, ex. Sharpened stick, woven mat, or ceramic
Helps find patterns and trends
Shows how humans interacted and adapted with their environment
Disclose information about prior habitats, including historical temperatures, vegetation, and animal populations
Replicate past environments and how they changed over time
Kelp Highway Hypothesis
First Migration:
The Kelp Highway is the first migration with few human induced extinctions, diverse subsistence strategies, use of marine resources, earlier migrations are possible
* Multiple in-migrations from at
least 15 kya
Clovis culture
Early hunters of megafauna in North American known by the distinctive point of their spear tips, the Clovis point
Clovis First Hypothesis
Highly mobile hunter-gatherers spread throughout N.A. in just a few centuries and dispersed rapidly into the unoccupied areas
Several Clovis sites have evidence for the butchered remains of Mammoth and Mastodon associated with Clovis points
Explains the rapid dispersal through the New World
Archaeological finds support pre-Clovis
occupation of New World
Lithic tool anatomy (e.g., dorsal/ventral sides, flake scars, bulb of percussion)
Most recovered material culture in the archaeological record
Used for a long time – majority of human existence
Ex. Groundstone or Flaked stone tools
Successful adaptation to hunting and gathering
It’s technology as evidence of human adaptation to climatic change
Fueled by communication and cultural transmission
Flintknapping
the act of striking a flint to remove a piece, or a flake, usually to make a stone tool. The people who do this are called flintknappers
Ethnoarchaeology
The study of modern processes in present-day societies in order to draw conclusions about past societies from their material remains
Domestication
A biological process where plants and animals become genetically changed as they rely more on humans for their survival and reproduction
The evolutionary fitness of both humans and domesticated is increased.
Pottery/ceramics
Vessel Size (Larger Size = larger social group), Communal or Individual
Pots as Tools
Functional Attributes = Shape/Size,
Surface treatment
Specific to archaeological period (provide relative date)
* Temporal type
Diagnostic ceramics
Category of ceramic sherds that indicate something specific
