Making Living - Lecture Flashcards
What is adaptation?
A process by which organisms develop physiological and behavioural characteristics that allow them to survive and reproduce in their environment.
What is adaption an interception between?
- changes an organism makes in environment
and - changes the environment makes in organism
What is interaction between us and the environment?
Adaption
Why were lifestyles encountered by Europeans the way they were?
Because the environments had been the same way for a long time ~3000-5000 years.
-When the environment is stable, people don’t need to modify and adapt because their life is stable.
What are the two types of environment?
physical or anthropogenic
How is adaption of humans achieved?
- Achieved genetically and physiologically, like in other species by means of natural selection.
Yet, adaption in humans is mainly (not exclusively)___and this differs us from other species.
cultural
What are the three parts of human adaption?
- ecological adaption
- social adaption
- psychological adaption
What is a balance between environment and physiological response of humans to the environment
adaption
What do changes in environment introduce in humans?
introduce changes in humans at basic physiological level.
What differentiated us from other species?
culture
How do humans interact with environment?
through production
- patterned and organized activities by which people transform natural resources into things (products) that satisfy their needs/wants.
What 3 things does production (a social activity) involve?
- the division of labour
- patterns of cooperation
- allocation of rights to resources
What are the 3 components of production?
labour, technology, resources
Why do we interact with the environment?
for purposes of satisfying needs
What are the 5 patterns of adaption (aka patterns of subsistence)?
- foraging (hunting and gathering)
- horticulture (incl. slash-and-burn cultivation)
- intensive agriculture
- pastoralism (or herding)
- industrialism (including mechanized agriculture)
Describe the lifestyle of foragers? (4 points)
- move about a great deal
- seasonal congregation and dispersal
- small size of groups (bands)
- populations stabilize well below the carrying capacity of their land
What is the average size of foraging bands?
fewer than 100
What is carrying capacity?
Is the maximum population size that the environment can sustain at a given level of technology, without depleting itself.
What is the oldest subsistence pattern?
food foraging
How many people today are foragers?
half a quarter of million people today
Why do foragers need to move around a lot?
because their resources are limited, season nd climate change
What is an example of foragers?
Ju’ / hanse
How are foraging societies usually perceived?
Starving, malnourished, no social or cultural life.
What are foraging societies like in actuality?
They are well nourished, cultural (they meet each other often, visiting neighbours). Women spend more time in camps, whereas men hunt.
What is an example of an egalitarian subsistence pattern?
foraging
What is an egalitarian society?
sharing, everyone gets same amount of food/resources
How is wealth NOT viewed in foraging societies?
Not viewed as money and surplus of food.
What is their a low density of in foraging?
social relations
