BIO 358 4 Flashcards
scale of individual speicialization
-immensely large bc we can directly and indirectly share cultural information
primary coalition
- finite size group
- scale of cooperation that produced the original origin of humans
- capable of developing a level of adapted sophistication -> advanced stone tools
- Neanderthals and modern humans
- internally highly cooperative
- xenophobic towards externals
- they cant control conflict between these coalitions
enlarged coalition
- leads to higher level adapted sophistication
- increased individual specialization
neanderthals
- large brains (slightly larger than our!)
- have the same common ancestor as us -> homo heidelbergensis (.5 mil years ago)
- evolve in eurasia
- cooperate at the level of primary coalition
50,000 years ago
- expanded coalition
- behaviorally and anatomically modern
- new weapon must have been developed -> expanded social scale -> adaptive revolution
hypothesis
- cognitive hypothesis
- behaviorally modern humans sustained social revolution -> better supported
- behaviorally modern humans sustained a behavior improving genetic change -> not as well supported
tool sophistication
- adaptive revolution
- pre-human make tools (2.5mil years ago)- oldowan tools
- first humans make more sophisticated tools- acheulean (knife, symmetrical)
- (5,000-7,000 years ago)- mousterian (levallois) tools -> slight improvement
- modern humans- produce much more sophisticated tools -> increased individual specialization (enlarged coalitions)
art
- adaptive revolution
- require very sophisticated expertise
- individual specialization
- pre-modern humans- simple, child like art -> primary coalitions
- modern humans- much more sophisticated art -> enlarged coalitions
geographical range and ecological impact
- adaptive revolution
- behaviorally modern humans are able to sail
- 13-25 thousand years ago
- vast expansion of geographical range
- set off massive extinction -> better hunters
controlled burning
- adaptive revolution
- behaviorally modern humans
- not too hot that is rises and burns trees
- kills ticks and flees
- humanizes the environment -> extinction of a lot of animals
hopewell
- mound
- behaviorally and anatomically modern humans made this
- requires a massive scale of social cooperation
- built the great circle at newark, ohio
- evidence that behaviorally modern humans commonly acted socially on much larger scales than premodern
currency
- public market
- economic exchange
- currency
- durable
- difficult to counterfeit
- coercively suppress theft
- use of medium of exchange
- use beads
- originate with behavrioally modern humans -> due to social
secondary coalitions
- primary coalitions cooperate
- leads to emergence of currency
- expanded labor forces
- social scale increases
favor exchange
p=n(n-1)/2
- total unique pairwise interactions (p) in a population of n individuals is given by the equation
- limits the scale we can cooperate purely based on favors
- we require currency
- keeping track of tasks/favors becomes more and more difficult -> exponentially
public market exchange
- mediated by currency
- monitored
- reciprocal
- secondary coalition
- in the middle of the circle and coercive weapons (atlatl) surrounding
- one entrance/exit
- burrow pit on the inside
- policing
- instantaneous value
- public so everyone can monitor
- primary coalitions engage
- organized crime -> policing is required
- require records, currency
- xenophobia can be overcome if you can police on a larger scale
- primary coalitions come together to exchange with policing
new coercive weapon
-should appear with adaptation of currency
organized crime
- primary coalition
- parasitic
- needs to be coercively suppressed
no lanchester advantage
- one on one
- primary coalition vs primary coalition
strong lanchester cost reduction
- emerged with the atlatl weapon -> spear thrower
- long distance weapon
- primary coalition is coercive from a distance
- harpoon point
- applied hunting tool to social coercion
primary -> secondary coalition
-a weapon capable of INTERNAL law enforcement allowing the next scale of social cooperation to emerge
social coercion theory
- self interested origins of the weapon: intergroup conflict or hunting NOT the focus
- we create weapons for intergroup conflict and hunting
- we are unique bc we have intergroup (internal) group coercion
- allowed the merging of groups that now would share cultural information, specialize, exchange fruits of labor
- scale and structure of cooperation is subject to effectiveness of the weapon when redepolyed
inuit
- use simple old tools and use it in a behaviorally modern coercive way
- use local knowledge
- teamwork
- supplement seal diet
- support of the village and opportunity in village making this an adaptive opportunity despite danger
- social scale is smaller due to the simplicity of the weapon
pre-historic history
-1.8mil years ago
history class
- propaganda
- not true
- doubt everything
what does history look like: empirical matter
- rise of homo 2 mil years ago
- elite throwing, hypercultural, expanded cranial volume, adaptive sophistication
adaptive sophistication (an adaptive revolution)
- staircase
- with new scales of cooperation -> adaptive sophistication explodes
- tool sophistication
- tools accumulate
- cutting knife rock- 1.6 mil
- how did we get from rock to airplane -> empirical record shows that there are adaptive revolutions
- adaptive revolution- abrupt progress
- adaptive stasis- stand still after adaptive sophistication revolution
- > adaptive staircase
- new coercive technologies
currently we are in
-adaptive revolution
how does social coercion theory predict history
- control of conflict of interest associated with transmission of cultural information with non-kin
- acquire vast amount of cultural information
- we are the pedagogical animal -> teaching and learning
- we are the economic animal -> we trade skills and good
- we can indirectly and directly exchange skills -> we dont know how to pick corn, build houses, make clothes
the scale of uniquely human hyper cultural cooperation matters
- more people -> more expertise -> more manufacturing -> short time for transmission of culture
- scale matters!
- less people -> slower transmission
- ex. tasmania- 50,000 yrs ago- advanced tools -> 8,000 years ago- flooded -> after the flood the technology went back to primitive technology (paleolithic) bc they were isolated and small -> couldnt transmit culture
- loss of cultural sophistication
- adaptive sophistication is limited by social scale
ice age
-every 50,000 years there are cyclical ice ages
50,000 years ago
- tools become more advanced
- harpoon
what controls scale?
- coercive tools control scale
- rapidly drives a adaptive revolution
internal social groups
- humane
- cooperative
between social groups
- xenophobic
- hostile
carnacioles
carnivore teeth
- austrolopiths make hypersharp tools for ripping meat -> flint and obsidian are good resources
- crushing stone- crush marrow
australapith
- brain is ape sized
- garhi fossil- little anatomical difference from australopith fossil -> both associated with fossil prey and manuports
- suggests that power scavenging adaptation might have been the first step towards human emergence
- leg lengthening
- 2.3 million years ago
- manuports (ammunition)
- associated with fossil prey processed with stone tools
- elite throwing
- power scavenging
- kin selected **
bacteria vs. non-humans and humans
- bacteria have genetic information
- we differentiate bc we have cultural information too
evolution
- significant genetic adaption to initial increase in scale of social cooperation
- subsequent evolutions or NOT genetic they are social or cultural
- new coercive technologies drive revolutions
- increase scale of cooperation a million fold in just 10,000 years
- massive new social scale causes problems of adaptive novelty
- these processes of social change do NOT necessarily produce increase in dibidual human welfare
- we must humanely manage
rice, potatoes, corn
- responsible for 95% of calories
- remaining calories is wild food
- these foods depend on us to control weeds for us
- human domestication
- mutual
bow
- 14,000-1,000
- 12,000 BCE
- coercive weapon is the bow
- supplies food
- bow is easy to use but complex
- atlatl is easy to make difficult to use
- bow is lethal
- opportunity costs are very different
- immediately humans live in large permanent settlements for the first time with emergence of bow
- specialization growth -> arts, currency
- professionalized food production -> agriculture
- agricultural revolution occurs right where bows are invented
bow vs atlatl
- bow is easy to use but complex
- atlatl is easy to make difficult to use
- bow is lethal
- opportunity costs are very different
- opportunity cost of bow is low
- opportunity cost of atlatl is high
- atlatl you must practice a lot
- atlatl depends on mass of projectile and human strength -> bigger points -> behaviorally modern
- bow doesnt need to be heavy -> smaller -> neolithic
native american
- transition from atlatl to bow is associated with much lower opportunity cost
- social structure dramatically shifts
teosinte
- smaller
- ancestor of modern corn
- maize
- domesticated to corn
landfill
-garbage is dumped everyday
-
neolithic dating
- containers -> technology evolved quickly
- different styles evolve
- arrowheads evolved -> bigger head for atlatl and smaller for bow
- C-14 dating- determines how old a plant or animal that eats plant is
- tree ring dating- dendrochronology -> dates wood
- trees grow based off warm and wet (fast),cold and dry (slow)
- bar code like -> dating to the year
why do humans remain local
- xenophobic
- trading
- crops is limited (depending on weather and soil)
- weapons spread everywhere
agricultural revolution: natufian culture
- first fertile area that has the bow
- fertile crescent
- excavation
- build a house -> breaks down -> tell -> self midden
- town is abandoned and forms giant hill
- no agriculture revolution yet
- bow is found
- several thousand years later -> argiculture comes about
- needed time for domesticaiton
- domesticated: wheat, barely, rye, sheep, goats, cattle, pigs
- different specialization and trading
china
- two different types of rice
- millet
- soybeans
- agricultural revolution only arises after the bow arrives
- about 3,000 years later
africa
- cattle
- yams
- sorgum
- bow doesnt come until about 3,000 years ago -> agricultural revolution
north america
- native american
- neolithic revolutions happen much later bc bow arrive is delayed over ocean
- maize, beans, squash -> mesoamerican triad
- these triads come before the bow and only explode until after the bow
- these crops used for horticulture (family gardening)
- only after the arrival of the bow do we see agricultural revolution! (400-600 CE)
north america: Mississippians
- extends throughout Mississippi
- a lot of trade
- atlatl policed
- hopewell existed in middle woodland dwellings
- beans, maize, squash
- not sedentary
- after the bow -> immediately sedentary communities, and then agriculture
- monumental architecture
- social event
- cahokia
- monks mound
- explode from bow
north america: chumash
- santa barbara channel (cali)
- neolithic revolution here wasnt agricultural
- powerful marine food chain was here
- sandy, rocky, beachy
- acorns
- professional fishers
- boats
- ceramics
- explode from bow
north america: calusa
- southern florida
- neolithic revolution is not agricultural
- algal bloom -> creates food pyramid
- estuarine environment
- marine food is rich
- hill built by food residue was found -> snail and mollusk shells
- sites were abandoned and people harvested and made fish oils with the arrival of bow
- mound key
neolithic (agricultural) revolution
- adaptive revolution
- scale
- sedentary settlements
- fishing or agriculture
- bow starts this -> greater range, much lower opportunity cost
- police cooperation
- produce food on a large scale
- 14k years ago
- domestication
north america: anasazi
- basket makers
- pit houses
- small and moved
- bow comes and they become sedentary
- agricultural revolution
- huge settlements
- chaco canyon
- pueblo bonito
- irrigation system
- pottery
- stones men
- astronomers -> seasons to farm
- measures solstice and equinox
- massive specialization
archaic state
- emerged from ancient evolved biology
- ethical humanity
- 5,000 years after agriculture
- body armor and shock weaponry**
- shock weapons- swords, spears
- elite control of coercive threat (non-democratic) -> only given to males
- body armor disables projectile weapons
- rapid revolution (from these armors) led to archaic state
- led to central city state (larger) with satellite settlements surrounding -> large economic unit
- elite males are in control and towns serve them
- women are not citizens
- bronze metallurgy (iraq- sumara, egypt) -> iron metallurgy (turkey)
- transfers Neolithic states into empires
- land expands but the wealth doesnt -> poverty
- public brutality
hierarchical coercive power
- body armor
- elite control of coercive threat -> only given to men
- this changes us (we are not democratic and equal anymore)
- people are working in their own self interest
democratically
distributed access to coercive threat
- elite throwing
- bow
- atlatl
- projectiles
- men, women, children are equally powerful
- bc we are self interest we all cooperate so we all dont get hurt -> this changes with body armor
- democracy requires cooperation and each person
hoplite
- armored warrior
- gives elite power over commoners
- elite warrior
- shock weapons + body armor
- body armor disables projectile weapons
body armor
- expensive to make -> limits who can have
- expensive opportunity cost too -> you must train to fight without weapons
- disables projectile weapons
- brings about elite control of coercive threats
- mostly only given to men
- no longer democratic
- archaic state
- pregnant and nursing females cant fight
archaic state: egypt
- rapid development from archaic state
- structures are hugely larger
- pyramids
bronze age
- scale armor- metal technology stitched together
- first armor
- shell armor is made after -> continuous
- bronze metallurgy (3500 BCE)
- birth of archaic states almost immediately after
- sumera, egypt
- hierarchal
mesopotamia
- first bronze armor ever
- Egypt picks up up after
- then mycenaeans
- minoan
iron age
- metal ore is discovered from pottery
- iron ore is in red soil
- labor intensive and requires specialization
- opportunity cost is high
- blast furnace- forced input of oxygen -> super heated -> fuel is charcoal
- its not cheaper but its more abundant than copper -> more available
- religion -> domesticated by male elites to gain submission
- larger and more powerful than bronze states -> hierarchal -> poverty
copper
-will melt
-flexible
-alloy it with zinc -> brass
-alloy is with tin -> bronze
-birth of bronze age
-
steel
-introduction of carbon into iron -> steel
athenian and spartan

- political figures dress like elite males (armored) bc they are the ones voting
romans
- architecture- roads- trade, transport
- aqueducts
- symbolic expression- statues
- octavian- caesar augustus -> first roman emperor
- his statue shows him in armor and shock weapons
japanese state
- samurai states
- archaic states lag bc its far
- kusunoki masashige- war lord- armored
afroeurasian
- male dominated
- turn females into property
- bc men are putting themselves at risk -> they want money and reproduction
western hemisphere (new world)
- mesoamerica and south america (not north america)
- armor is based on cotton
- kevlar- tightly knit
- each layer of kevlar absorbs momentum -> bullet proof vest
- will injury you but wont penetrate your body
- made by back strap loans
- elite male warriors -> archaic states
- kwatzoykoyotl
- obsidian (volcanic glass)- makes lethal shock weapons
- domesticates cotton
- not in north america bc the temperature doesnt allow
mayan
