adaptation
the interaction process between changes an organism makes in its environment and changes the environment makes in the organism
Tsembaga of New Guinea
raise pigs, which they sacrifice as as a symbolic end to hostilities. cyclical KAIKO FEAST keeps pig pop. manageable.
Anthropogenesis
Changes in the environment which are a result of man’s activities are the result of anthropogenesis (this is in Greek and means ‘man created change’)
Malaria and the Environment
slash and burn allowed water to pool in africa allowing mosquitos (malaria carriers) to thrive
Sickle Cell Trait
Sickle cell trait helps a person survive malaria
Ojibwa in Eastern Canada
moved to plains and altered lifestyles upon european arrival. went from sedentary to nomadic
Convergent evolution
occurs when two groups with different cultural backgrounds independently come up with the same solution to a similar environmental problem.
Parallel evolution
happens when two cultures with similar backgrounds come up with similar solutions.
Subsistence Patterns
Strategies used to acquire food . affects every other aspect of culture
Food Foraging (Hunter-Gatherers)
oldest and most universal means of subsistence
90% of all people who have lived used this lifestyle to survive
today’s foragers live in marginal areas
Characteristics of Foragers
residence is based on where the resources are, and this will change with the seasons - mobility and nomadism are common
may have regular or annual patterns of movement based on what resources are available when
location of water source is critical
foraging Carrying Capacity
group size tends to be small, fewer than 100
carrying capacity (# of people the land can support) is important and includes tool and other requirements
number of people in the group tends to stabilize well below the environment’s carrying capacity, sometimes 1/3 to 1/5 the numbers the home territory can support - this rarely exceeds 1 person/sq. mile
three crucial elements of social organization developed in foraging cultures
Sexual division of labor
Food sharing
Camp is the center of activity
foraging Sexual Division of Labour
hunting/butchering of large game, processing of hard raw materials are almost (but not) always masculine occupations
women tend to gather and process vegetable foods, do domestic chores
womens work in foraging
can be just as demanding as mens work
requires women to be able to stop what theyre doing to tend to children
60-70% of foragers’ diets is gathered by the women
Food Sharing
this is not typical among non-human primates
may have taken place as men and women would supply different food stuffs
forager Camps
location to congregate
focal point for activity and sleeping place
can change (on regular basis) according to access to resources
Egalitarianism
lack in different statuses in foraging societies because of the impracticality of carrying possessions around
no private ownership
hoarding/excessive possessions is very frowned upon
foragers Status
only differences in status are age/sex based
each sex has its own exclusive rituals that the other is forbidden to be a part of
women are not controlled by men
elderly help w/ childcare and knowledge
General Characteristics of foragers
small group size (usually <100), but can be higher in some circumstances
mobility, but if the environment is rich, may be more sedentary
social networks and food sharing
keep population levels below the carrying capacity
few material possessions
tend to be egalitarian
division of labour
Gathering
the collection of wild plants, eggs, small land animals, and shellfish – some would include insects as well
technology needed – digging sticks, carrying containers
Hunting
actively searching for, killing, butchering, and consuming animals (both mammals and non-mammals like birds and reptiles)
domesticated animals are not hunted
hunts are successful 10% of the time
Fishing
obtaining fish or sea mammals using any technique
can involve nets, spears, traps…
Scavenging
is associated with people obtaining animals that have been killed by another animal or are already dead
humans are opportunistic scavengers and will take advantage of what is available to them, especially if the carcass is large and the risks taken in obtaining it are low
it has been argued that scavenging preceded hunting as a subsistence strategy
