Anthropology and its 4 subfields
Archaeology’s Strengths
culture change and variation through time and across space
Holism, Relativism, Comparison
holism
all aspects of human variation are relevant and interdependent
comparison
comparison of cultures or adaptions for generalization and prediction when possible
cultural relativism
the idea that different cultures need to be understood in their own terms instead of the standard of others
Culture vs. Archaeological Culture
culture
the primary means through which human social groups vary and reproduced
material culture
interest in patterns an processes
archaeological culture
materials that co-occur in space and time
Archaeological Record
archaeological record initially forms through the actions of humans
Provenience
the location of materials in three-dimensional space
traditionally recorded by hand using rulers, tape measures, etc.
Context
an interpretation of the association of objects
Association
spatial relationship of different things and places
without provenience, context and association we learn less about the past
Artifact, Feature, Ecofact
artifact:
portable, modified objects
additive: created by adding materials together like pottery
subtractive: remove material from and object to create something like stone tools
composite: combining different finished objects together, spear
ecofacts
unmodified or non-tool materials that result from human activity
ex: human remains, animals that live in proximity (commensal species), pollen and charcoal (environmental proxies
features
non-portable objects and combinations of artifacts
hearth - pit or surface used ot burn materials
storage pit - pit used to hold materials, maybe be reused as garbage pit
post mold - hole left behind after a post has rotted away
structure - combination of architectural elements (walls, floor, roofing materials)
Archaeological Site Variation
Scale and site types
scale
the size of an area studied or described
the significance of spatial patterning varies by scale
small scale: objects and features
medium scale: sites
large scale: region or landscape
time scales:
the duration of time for a series or events to occur
geological: long term (hundreds to millions of years)
generational: over the course of a few lifespans
events: instantaneous moments
Primary vs. Secondary Refuse
primary
materials deposited where they were used or produced
ex: trash receptacles in separate rooms
secondary
materials removed from their place of production or use
often combined with materials elsewhere
ex: trashcans for all household gargage
Anthropogenic
disturbances caused by humans such as digging, deposition and recycling
palimpsest
something that has been altered or resued but still retains trace of its earlier form
ex: writing material used one or more times after earlier writing has been erased
Activity areas
locations where objects, features, ecofacts may be concentrated
differentiated by distance between objects, density and kinds of objects
disposal patterns
the context of discard influences what we know about the use of spice
Methods of Archaeological Discovery
Survey
Remote Sensing
the art and science of obtaining information about an object without being in direct physical contact with the object
provides capability of efficiently identifying patterns and recovering information about archaeological landscapes
still must archaeologically test features identified in remote sensing
terrestrial remote sensing
using techniques to identify below-surface anomalies that may be features, with the goal to identify nature and distribution
aerial remote sensing
LiDAR
laser scanner collects large quantity of elevation points
uses in forested regions
underwater remote sensing
Excavation
size and extent of excavation units depends of research question and nature of archaeological record
after excavation obects are curated so future generations can study
Relative Dating Techniques
Stratigraphy
recognition of different layers in the ground formed by natural or human deposit
primary source of chronology
Law of Superposition
younger layers lie on the top of older layers
provides framework for ordering archaeological finds
Cross-Dating
use of materials dates at one site to infer the age of similar materials at another site
Index Artifact
objects with restricted temporal range and dinstinct morphology/construction
Absolute Dating Techniques (what is dated, how far back in time can the technique be used, important assumptions of the method)
Dendrochronology
using tree rings to determine the age and climate conditions
not every tree species is suitable
trees add one growth ring per year
Radiometric techniques
Radiocarbon Dating
used to death of organism using date bone, teeth, plant material, shell, ect.
Potassium-Argon Dating
used to date volcanic eruptions using layers of volcanic rock and ash
Site Formation Processes (Geological, Biological/Bioturbation, Anthropogenic)
Taphonomy
the study of the formation of the archaeological record
post-depositional process
processes that occur after something is put in the ground that influence what is how is preserved and how
Pompeii Premise
the assumption that what we find in the ground represents exactly how people in the past left it
Geological
Disturbance caused by earth processes like chemical weathering, deposition/erosion, sea level change, catastrophic events and temperature change
bioturbation
disturbances caused by organisms like digging animals and vegetation
Sources of Inference
Ethnoarchaeology
Experimental Archaeology
Archaeological Techniques
Ancient DNA
Stable Isotope Analysis
stable isotopes are incorporated into living animal tissue from the environment
ex: shellfish incorporate oxygen from water into their shells
isotope ratios vary by season due to temperature or rainfall
Preservation
some conditions that promote organic preservation
anaerobic such as low oxygen
neutral soils such as low acidity
constant environment such as temperature and humidity
destruction
many objects are preserved by burning
fire carbonizes organic matter
much more chemically stable
conditions for good preservation
stable geology/hydrology such as caves
few microbes such as under water, mud and clay
constant temperature or constantly wet or dry
chemical stability such as fire or balanced pH

Archaeological Ethics:
Cultural Resources
the evidence of past and contemporary cultures
physical such as objects and places
intangible such as language and knowledge
Threats to cultural resources
looting
for economic interest in the past
collecting
antiquities markets fuel destruction such as art collector and museums
organized crime including drug cartels
war and conflict
intentional harm directed at places of cultural importance
items perceived to be valuable on the markets are looted and trafficked
development
US housing boom
international development projects
climate change
rising sea levels erode cultural sites
changing temperatures impact soil and stratigraphy
long-frozen deposits can melt
Cultural Resource Management
federal laws mandate that projects with federal funds and permits identifying significant cultural resources within project areas
ex: pipelines, road construction, wind turbines
basis for cultural resource management (CRM)
most professional archaeologists are in the CRM industry
Anthropology and the ownership of the past (Who owns the past?)
complicated issues because of many interested parties
from a universal perspective cultural resources should not belong to anyone
Federal Laws
ARPA
protects cultural resources on federal property or stored in places with federal funding
NAGPRA
“Kennewick Man”
human remains identified causing long term court battle amongst local indigenous communities
Native American Graves Protection and Repatriation Act
legislation for protecting and repatriating burials on federal or tribal lands
Ethical Archaeological practice
Kinds of stewards
academics
trained, have research focus, publish
indigenous
protect and interpret own cultural heritage
private sector
trained, research driven by market (CRM)
avocational/amateur
generally untrained, but volunteer and provide information to professionals
