what is neolithic also known as?
-the new stone age
what occurred during the neolithic?
-intensification of resource management
what are the two parts of the early neolithic and what are their dates?
-pre-pottery neolithic A: 12,000-10,800 ya (late dry period)
-pre-pottery neolithic B: 10,800-8,500 ya (improved climate)
what is domestication?
-human manipulation through artificial selection, either intentionally or unintentionally, results in genetic changes in a species that prove beneficial to humans
what happened during the pre-pottery neolothic A?
-plant domstestication
what happened during the pre-pottery neolithic B?
-farming
what are the domesticated crops during the neolithic?
-cereals (wheat, barley), pulses (lentils, peas), legumes (bitter vetch, chickpeas)
what are the major domesticated plants in SW Asia, SE Asia, North America, and South America?
SW Asia: wheat and barley
SE Asia: Rice and Millet
NA: corn
SA: potato and cotton
what were the major domesticated animals in SW and W Asia, China and eastern Europe and when were they domesticated?
Dog: 25,000-20,000 ya (SW Asia, China)
Cow: 8,000 ya (SW Asia)
Sheep: 10,000-9,000 ya (SW Asia)
Goat: 10,000 ya (SW Asia)
Pig: 10,000 ya (SW Asia, China)
Horse: 6,000-7,000 ya (eastern Europe or western Asia)
what is domestication syndrome?
the collection of physical and behavioural traits that are shared among domesticated animals
what is the most widely shared change in domesticated animals?
tamer behavior compared to ancestors, people most likely selected for the trait via artificial selection
are other domesticated traits that are shared usually less useful to humans and the animals themselves?
yes, smaller teeth, smaller faces, different color of fur, skin, and feathers etc.
does selection for tamer behaviour cause other traits to be selected due to them all being linked by genes controlling neural crest cells?
yes
what is the new model of domestication syndrome?
-domestication is not caused by selecting animals for tameness but by unintended shared effects from the new domestic environment
-removal of pre-existing selection (domesticated animals are protected from predators, so wild traits to avoid them are lost)
what are the four ways domestication disrupts natural selection shaping animals?
did humans domesticate sheep 8,000 ya in turkey?
yes
were human migrations fueled by sheep herding and exploitation of products?
yes, people brought their flocks with them when migrating
why is early neolithic tech distinct from previous periods?
-early neolithic shifts away from bladelets and uses larger blades
what is in the toolkit of early neolithic?
-sickles
-stone axes
-adzes
-grinding stones
what appeared during the pre-pottery neolithic A when talking about settlements?
-the first evidence for communal structures
what is the Jericho Tower?
-the most impressive communal structures form the pre-pottery neolithic A
-9 m high, undressed stone and mud brick
-attached to a massive wall
did settlement size increase during the neolithic A and were the houses still circular but larger than natufian ones?
yes
what occurred during the neolithic B?
-round houses turned into rectangular houses
-settlement size increased
-rectangle houses allowed for more densely packed space
-villages had high degree of planning
were skulls plastered during the neolithic?
yes
