holistic and integrative study of human species.

culturual ecology
julian steward/ grahame clark - culture represents uniquely human form of adaptation to environment. diversity of human culture reflects a diversity of adaptations aimed at living successfully in a particular ecological niche
-
processual archaeology
lewis binford -
rigid scientific methods.
close examination of adaptive processes structuring prehistoric social and economic life - scientism (critique of processual archaeology)
- belief that scientific method is infallible and always yields the truth
- types of material culture
-
1 artifacts (any object modified by a human)
2 ecofacts (diet/economy)
3 cultural features (non portable remains)
4 sites cluster of artifacts, ecofacts or features - subsurface testing

2 electrical resistivity survey
3 ground penetrating radar
4 shovel testing - proton magnetometry
-
finds magnetic anomolies
negative interference from electrical storms, iron fence, wires - electrical resistivity survey
-
probing ground, cheaper, walls contain less water therefore less resistance
groundwater interferes - ground penetrating radar
-
radar pulses
works best with well drained souls with low clay content - shovel testing
-
transect a line of systematically located test pits
looking at known sites or random testing - arch survey methods
-
asking locals
often near places that seem comfortable to live in
aerial photography
satellite imaging -
horizontal provenience
vertical -
spatial position of object related to fixed point (datum)
same, but can determine rough age, law of superposition - stratigraphy and law of superposition
-
relative dating techniques
stratigraphy: arrangement of soil and rock in layers
law superpos. : deeper stuff is older - seriation
- relative dating technique, establishing a relative chronological sequence using the pattern of replacement of styles of a type of artifact
- radiocarbon dating
- absolute dating, uses carbon 12 and 14, 14 is radioactive, half life of 5730 yrs. living things ingest c14, stop ingesting after death. measures c14 to c12 ratio. organic material. range up to 70,000 yrs
- dendochronology
- using tree ring sequences for absolute dating. california crystal pine first to be sequenced.
- potassium argon dating (K/Ar)
- measures decay of K40 to AR40, dates volcanic rock, useful for 100,000 yrs old and onwards
- fission track dating
- used on volcanic rock, measures ages from 1mya to 100,000 ya. measures uranium decay
- thermoluminescence dating
- used on rocks, minerals, pottery/ceramics, can tell how long since item was last heated. 300ya to 100,000 ya
- electron spin resonance (ESR)
- applicable to teeth thousands of years old onwards, also on limestone, coral, shell
- obsidian hydration
- used for dating obsidian (volcanic glass) artifacts as old as 120,000 yrs
-
N (natural) transforms
site formation process - wind driven deposits, erosion, animal disturbance
-
C transforms (cultural)
site formation process -
human activity changing sites:
garbage, what people take vs leave, plowing, developing - site formation processes
-
1. deposition (midden/cemetary)
2. reclamation (historic period fragment made into game dice)
3. disturbance (plowing/erosion)
4. re-use (item reused in variety of ways in same context) - ethnoarchaeology
- observing living people to understand how archaeological records are produced
- palynology
- IDing plants through preserved pollen remains
- phytoliths
- microscopic fragments of silica produced by plants
- sea and ice core analysis
- can determine if it was warmer or colder
- ethnographic analogy
- using ethnographies to study archaeological sties of living peoples
-
zooarchaeology
min. # of indivs (MNI)
# of indiv. specimens (NISP
meat yield estimate -
sort by species to ID MN of animals
count each bone frag as indiv. to give largest # of animals
how much meat each animal contributes to overall diet - reconstructing social systems
- bands + tribes / chiefdoms and states
- reconstructing ideology
- study of human remains, species ID and definition

true breeding -
bred peas
produce same traits as parents - genetics
- study of mechanisms of inheritance
- genotype
- total genetic info carried by an indiv.
-
DNA
types -
molecule that carries genetic code
nuclear: found in nucleus, inherited from both parents
mitochondrial: outside nucleus, only from maternal - chromosome
- strand of DNA in the nucleus of cells
- gene locus
-
point on a chromosome where two sets of genetic instructions are found
(sets are alleles) - population
- a group of organisms capable of forming mating pairs
- breeding pop.
- a pop with some degree of genetic isolation from other pops. of same species
- gene pool
- total amount of genetic variability within a breeding pop
- phenotype
- observable characteristics
-
discontinuous variation
continuous -
phenotypic traits are discrete (eg A B O blood types)
traits are blended (eg body size and shape) - hardy weinberg theorem
- formula used to calculate expected frequency of genes by comparing the genetic make up of a real pop. to a hypothetical one that is free from evolutionary forces
-
forces of evolution
1. mutation
-
1. chem change in gene structure 2. change in order of chromosomes 3. change in # of chromosomes
-
forces of evolution
2. Natural selection - 1. stabilizing ( human body size) 2. directional; continuously increasing trait 3. diversifying: extremes among averages (new species, blood type etc)
-
forces of evolution
4. gene flow -
transports alleles from one pop to another through interbreeding
increases variation within pop, decreases between pops.
-
macroevolution
1. speciation -
appearance of new form or species
1. gradualism: suggests pops naturally change over time
2. puncuated equilibrium: pops develop to a state of stasis/equilibrium for a long time and then occasionally forced into new niche -
macroevolution
2. adaptation - adjustment of an organism to a particular set of environmental conditions
-
macro evolution
3. stasis - period of evolutionary maturity, stable status
-
macro evolution
4. extinction - ecological change, law of competitive exclusion, catastrophes
- mitochondrial eve hypothesis
- mitochondrial dna used to estimate the relatedness of 2 species or 2 diff pops of same species
