Chapter 7 Flashcards
Most ancient plant evidence
macrobotanical remains
how can plant remains be preserved
- waterlogging
- charring
- desiccated
waterlogging can preserve plants through
wet screening
charring can preserve plants through
flotation
desiccation can be preserved through
dry screening
best way to preserve plants
absence of moisture or fresh air
where can evidence of past behavior be preserved
- wells and pits
- hearths
- latrines
Wadi Kubbaniya
Four sites that have produced some of the most diverse assemblages of food plant remains
where is material concentrated in Wadi Kubbaniya
around hearths of wood charcoal
what was NOT used for the material at Wadi Kubbaniya
flotation
why was flotation NOT used at Wadi Kubbaniya
the material was fragile and disintegrate in water
what WAS used at Wadi Kubbaniya
dry screening
what is important in nutgrass tubers
tons of these tubers could have been obtained and could have resulted in a system being developed
when were nutgrass tubers eaten in Africa
when food was low
why were nutgrass tubers preferred over seeds
involved less work in processing
what was being studied at the Wadi Kubbaniya site
whether the occupation was seasonal or not
when was nutgrass avaliable
only half the year
does the nutgrass show that the Wadi Kubbaniya site could ONLY have been used seasonally
NO, there could have been food storages or other sources
what does it mean when plants are only available at certain times
clues about when a site was occupied
seasonal plants can show what
was eaten in a particular season
what do ripe seeds show
harvest time
what does past seasonality of plants need to be
predicted from modern representatives of the plants in question
what can food storage indicate
the site was used beyond the seasons of a specific resource
what is debated about some plants
whether they were wild or domesticated
what does domesticated plants show about society
how it shifted from mobile hunter-gatherers to a settled way of life
why is it not always easy to distinguish between wild and domesticated plants
the morphology doesn’t always change
what is little use for the study of domestication
pollen grains
why is pollen not useful in domestication
not able to differentiate between wild and domestic plants
Neolithic revolution was coined by
Gordon Childe
Neolithic Revolution is a period
when humans began cultivating plants, breeding animals for food and forming permanent settlements
what resulted in the birth of agriculture
Neolithic Revolution
what led to widespread development of settled village life
Neolithic Revolution
what were association of animal bones used for
proof that humans were responsible for the presence of faunal remains
what were many of assemblages NOT
associated with human tools
what is attempting to differentiate between marks on bones
those of human tools and those by other animals
cutmarks on bones are being examined to prove that humans were
genuine hunters or scavengers
what had to be used to examine cutmarks on bones
microscopes because the marks were too similar to the naked eye
what is used as a replica of bones
resin replicas
why were resin replica used to examine bones
- easier to handle
- easier to transport
- easier to store
- less fragile
what needs to be studied to prove human intervention with cutmarks
context of the bones
the amount of meat on bones depends on
- sex
- age
- season of death
- geographical variations in body size and nutrition
when is sexing easier
when the male and female are anatomically different
what can provide two distinct clusters of results in sexing
the different size of feet
large feet are more
males
smaller feet are more
females
what is age of bones assessed from
- degree of closure of the skull
- fusion of limb shafts and their epiphyses
what is age of prehistoric bones compared with
those of modern populations
how is the age an animal was killed estimated
eruption and wear patterns of the teeth
how can the seasonality of bones be studied
identification of species only available at a certain time of the year
what are bone samples from screening likely to have
more small bones
conditions for bone preservation differ
from site to site
working through a sample, bones are identified as being
- fully identified fragments
- undiagnostic pieces that might belong to one or several speices
Minimum Number of Individuals (MNI)
expresses the least number of animals that were needed to account for the bone sample
MNI calculations are based on
the most abundant identified bone for each species
when does MNI have little meaing
with small samples
Number of identified specimens (NISP)
simplest calculation of relative species abundance
what are the identified bones of each species expressed as in NISP
precentage of total bone sample
how could the NISP results be misleading by
sites with different ages, conditions of preservation or recovery standard
