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
