Q
explain the neolithic revolution and what happened during it

about 10 000 years ago
13
Q
what happened to the bearing straits as time passed?
A
the contrinets split and started moving further and further away from each other - an ocean can be found in between the two continents - asia and north america

increase in tree and shrub growth, reduction in grasslands
15
Q
how did climate change during the holocene?
A
see lecture videos
16
Q
what caused megafaunal die off (at the end of the last ice age 15ka - 10ka)

- appearance of megafaunal hunting humans
17
Q
describe the environment of the end pleistocene/early holocene period
A
Southwestern Asia =
- warmer conditions - immigration of new plant species into highland areas such as the Zagros mountains in Iran
- lots of wild cereal grasses emerge (wild wheat and barley which become staples for forager groups)
18
Q
describe the environment of North and Central America during the holocene period
A
- rising temps brought - thorn, scrub and cactus forests to mountain valleys - including ancestors of domesticated plants
19
Q
what is the meaning of forage
A
to collect or look around for food
20
Q
describe some changes in forager societies
A
- between 15 -10kya - decrease in world capacity for foraging lifestyle
- major increase in population
- increase in intensity of the quest for food
- change to a more diversified lifestyle
21
Q
what were some changes to create a more diversified lifestyle
A
- eating a wide range of plant foods
- change in diet, technology, society and other cultural patterns
22
Q
what were more changes in forager societies?
A
- more sedentary
- specialised technology
23
Q
examples of some specialized technologies from changing and modifying societies
A
- intensive exploitation of locally abundant and predictable food resources
- tools for the processing of plant foods
- storage pits to secure food for lean months
24
Q
problems that cause changes in forager societies
A
- restricted territories and less mobility
- increasing populations
- environmental variations that are unpredictable
25
what did some forager societies located in areas with rich food resources
achieved greater complexity
| first signs of social ranking
26
name one other change in forager societies with regards to social life
start of social ranking and complexity
| - kin leaders who monopolised trade and food resources
27
what are three things required for social complexity and explain how they aid social ranking
- populations must be geographically restricted (e.g. mountain ranges)
- resources must be abundant and predictable (fish, shellfish, nuts and seeds- these items are not easily exhausted)
- Imbalance between number of people and food supply - causes a forced need to intensify food gathering - need to control the intensification and ultimately causes the development of social structure- someone needs to take charge to ensure that food is provided
28
lecture 15
birth of the modern world - the neolithic revolution and the origins of food production
29
describe the environment during the pleistocene/holocene transition
- 20 000 - 10 000 years ago
- shift from glacial to interglacial
- became warmer
- massive reductions in ice sheets
- increase in sea levels
30
what significant impacts did sea level increase have on geography?
- Bering land bridge cut off
- north sea flooded
- Britain separated from the continent
- austrailia cut off from new guinea
31
describe the changes in vegetation, fauna, temp and rainfall during the transition
- rainfall increased
- northern latitudes - lifted from tundra grasslands to forests
- pleistocene mega fauna such as mammoth, bison, camellids, others became extinct
- all responsible for major changes in complexity among forager populations
32
consequences of changes in complexity among forager populations
- people began to be less mobile
- competition for scarce resources
- exploit greater resources
- changes in technology
33
describe some changes to technology
- downsizing of projectile points.
- specialized hunting weapons.
- bow and arrow.
- versatile toolkits.
- Nets for fishing
- storage technology, such as basket and clay-line pits for nut and wild plant seeds
34
what is the mesolithic period typified by?
- change in subsistence base from intensive big-game hunting to broad spectrum collecting
- fish, shellfish, smaller animals, plants
- some cultivation is apparent
35
what are cultigens?
plants that are cultivated but this doesnt equal domestication
36

37
what area was a major centre for domestication of animals and cereals?
- Ancient near east (today the middle east)
- farming at 10 000 years ago
- fertile river flood plains
38
describe the first domesticates?
- wild versions are already - edible and have high yields
- easily stored
- genetically similar to domesticated versions
- evolved for periods of drought
- they wont sprout in storage
39
emmer and spelt vs common wheat
- emmer - c. 10ka = a alot smaller, less food on one stalk
- spelt - c.7ka = longer and more food on one stalk compared to emmer
- modern wheat - a lot more food on one stalk, thicker stalk than spelt
- fast morphological change from wild to domesticated versions
40

- woodlands and shrubland - not great for cereals
| - worked very well for maize
41
what was the early form of corn called?
teosinte

c.8ka
49
what are the biggest consequences of food production?

| increase in health issues
54
name and explain the health issues that arise from the increase in maize consumption
