test #2 Flashcards
question: subsistence system vs diet?
- subsistence sys. = practices pop. uses to acquire food
- diet = food eaten
explain: stable isotope analysis (carbon and nitrogen)
- done on human remains
- carbon shows plant diet
⤷ c3: rice, wheat, barley
⤷ c4: corn, millet, sugar cane (more agricultural) - nitrogen shows meat vs plant consumption
⤷ meat + omnivores: higher n15:n14 ratio than vege.
⤷ marine carnivores: higher n15:n14 ration than terrestrial
⤷ more trophic lvls -> N increases
name + define: categories of subsistence systems
- hunter-gatherer/hunter-fisher-gatherer
- dep. mainly on var. of non-domesticated food
- 2 types: foragers and collectors - food producers
- dep. on 1+ domesticated food
- 3 types: horticulturalists, agriculturalists, pastoralists
name + define: types of hunter-gatherers
- foragers
- move ppl as needed
- change base camp regularly
- short day trips
- eats food in a few days
- good for harsh climates and small groups - collectors
- move food to the ppl
- long-term settlements
- longer trips
- store surpluses
- good for larger groups
⤷ if food source = large bc predictable
name + define: types of food producers
- horticulturalists: “garden”, many sp. in plots
- agriculturalists: cultivate small # of sp. in fields (large quantities)
- pastoralists: herding animals (milk, meat, etc.)
explain (case study): mariculture
- northwest coast
- clam gardens
- modified coast line to for large tidal pools to raise bivalves
- formally agri. society
define: domestication (w/ selection)
- plants + animals become dep. on human intervention to survive
- noticeable changes in morpho.
⤷ to improve food yield - selection: change in freq. of traits in pop. as a result of changes to fitness
explain (case study): wild vs domestic rachis
- stems of plants
- altered seed dispersal
⤷ to keep seeds for longer
question: macroremains vs microremains?
- macro: preserved plant components viewable w/ naked eye
- micro: smaller parts of plats viewable w/ microscope
name: feat. of sp. likely to get domesticated
- short generation time
⤷ prod. lots of babies - genetically plastic
⤷ easier to sel. for - tolerate human envrt. (ex. gates)
- socially amenable to humans (for animals)
explain: domestication and mutualism (how is it coevolution?)
- beneficial to both species
- humans get food, sp. gets to thrive and outcompete others
- may be formed through experimentation
⤷ lucky results
name + explain: upper paleolithic society
- foragers (hunter-gatherer)
- expanded to australia and the americas
- nomadic
⤷ groups limited to 75 ppl - no long term permanent vilalges
- mostly egalitarian
⤷ no status ranks
name + explain: mesolithic society
- extinction of large-game sp.
⤷ changed flora and fauna - shifted to broad spectrum collecting
⤷ less foraging - less nomad
question: where did agriculture and domestication originate?
- everywhere
- no one single origin
name: sites of domestication
- fertile crescent
- middle east area
- domesticated wheat and barley - mesoamerica
- domesticated maize, beans, and squash - highland/coastal andes
- domesticated llamas, alpacas, guinea pig, potato, and quinoa - china (yangtze river)
- domesticated rice and millet
explain (case study): wild vs domestic corn
- wild = teosinte
⤷ sel. for larger seeds led to maize - domesticated = maize
explain: neolithic package
- characteristics though to accompany the shift to agriculture
- domesticates
⤷ varies based on availability - pottery
⤷ storage and cooking
⤷ more beneficial for sedentary - ground stone tools
explain (case study): natufians
- neolithic
- used storage bins
⤷ shows surplus - had grinding equipment
⤷ shows ground stone tools - had elaborate burial packages
- more sedentary long term struc.
- early natufians had large villages
⤷ warmer temp. = more agriculture - late natufians had lower temps.
⤷ small villages
⤷ pop. decreased, showing signs of stress
explain (case study): catalhoyuk, gobekli tepe, jericho
- neolithic led to more complexity
- catalhoyuk: very large, dense, planned settlements (in turkey)
- gobekli tepe: more complex ceremonial life
⤷ ritual only space
⤷ built up and elaborated ovre time
⤷ shows extensive organization - jericho: elaborate mortuary practices
⤷ plaster heads
⤷ may represent emergence of inequality
explain: oasis hypo. (why was agri. adopted)
- agriculture = response to climate shifts
- gordon childe
- climate change in fertile crescent
- refuted by robert braidwood-jarmo
⤷ says envrt. wasn’t as swift as agri.
explain: population hypo. (why was agri. adopted)
- shift in strat. to support large pop.
- mark cohen: hunter-gatherer pop. saturation around 10000 ppl
- marvin harris: increase humans -> decreased big game animals
explain: stability and feasting (why was agri. adopted)
- shift from K to R sp. to encourage more stable food supply
⤷ ∴ can feast - bryan hayden
- K: live long, few young, susceptible to over-exploitation
- R: reproduce easily, resist overexploitation, easily reestablish themselves
- R supports more sedentism which stabilizes food supply
explain: how nutritional factor declines with agriculture
- dependence on 1 main crop and potential crop failure -> feast or famine
- changes texture and quality of food
- uneven food distribution
⤷ soc. class and status
explain: health effects of agriculture
- zoonoses: infectious diseases from animals
- sedentism: garbage and human waste accumulation (can cause disease)
- herd diseases: favours high population density
