Neolithic Revolution

When humans went from being hunter gatherers to settling in one place and farming

Definition of Domestication

Growing a plant or raising an animal, and thereby consciously or unconsciously causing it to change genetically from its wild ancestor, in ways making it more useful to humans.

Snail

First managed animal

Autocatalytic Cycle

Self reinforcing cycle - directional selection we have more food, then we have more people, then we need more food

Wheat and Barley

First stage of plant domestication

First fruit and nut trees (dates, olives, grapes)

Second stage of plant domestication

Fruit trees (pears, apples, cherries, plums)

Third stage of plant domestication

Wild plants (rye, oats, turnips, radishes...)

Fourth stage of plant domestication

Birds

Used for meat, eggs, feathers, fertilizer, pest control, sending messages.

Wolves

Used for hunting, companionship, protecting, herding, pest-control, sledding. May have been the first step to settled living as they acted as sentries for settled people, protecting them and their property

Dogs

Oldest fossil dates to 12,000 BCE. They may have disrupted the hunter-gatherer's taboo against private property.

Biomass

Living matter

Goats and Sheep

First stage of animal domestication

Pigs

Second stage of animal domestication

Cow

Third stage of animal domestication

Cheese

Documented in rock art from the 6000s BCE and in archaeological record from 4000s BCE

Lactose tolerance

The unusual ability to digest milk in adulthood. The best example of different groups of humans in different areas evolving in the same way in recent times in response to change created by human culture

Horse

Earliest evidence of domestication are bones with bit wear in Ukraine and Kazakhstan from 4000 BCE. Domesticated for military use.

Number of wild plant species in the world

200,000

Fertile Crescent

A geographical area of fertile land in the Middle East stretching in a broad semicircle from the Nile to the Tigris and Euphrates

Catal Huyuk

One of first true cities in history, created in the Neolithic Era in 6500 to 5500 BC, from which were created agriculture, trading, temples, housing, and religions

Egalitarianism

A belief in the equality of all people

Cross Pollination

When pollen is transferred from an anther on one plant to the stigma on another. This method may produce a variety of hybrids

Grafting

Placing a section of one plant onto another plant so that the section grows

Surplus of food

A main requirement for the success of all civilizations

Specialization of Labor

To train or specialize people in certain areas of work so that people can accomplish tasks more quickly

Dendrochronology

The process of counting tree rings to determine the age of a tree

Five factors that encouraged the switch from hunting and gathering to settled living

1) Decline in the availability of wild foods. 2) Spread of wild cereal grasses in the Fertile Crescent. 3) Development of technologies upon which food production depends. 4) A rise in food production/a rise in human population. 5) Food producers displaced or killed hunter-gatherers.

Negative results of settled living

1) Specialization of labor led to social classes and war. 2) Accumulation of wealth and possessions = greed and theft. 3) Higher population density increases risk of disease. 4) Health benefits of hunter-gatherers are lost. 5) Farming was difficult work. 6) End of the Egalitarian way of human equality.

Two ways food production spread

1) Ideas and domesticated seeds spread through trade. 2) Foreign traders brought food production and killed local Hunter-gatherers

Requirements to domesticate an animal

1) Herbivore. 2) Grow to full size quickly. 3) Mate in captivity. 4) Have nice disposition. 5) Must not panic and be prone to flight. 6) Have dominance hierarchies.

Volcano Hasan Dag

A volcano that provided obsidian, the source of wealth in Catal Huyuk.

Reasons Catal Huyuk Fell

Deforestation, overhunting, over cultivating, river changed course, accidental fires destroyed city's wealth

Biomass Inedible

1) Indigestible. 2) Poisonous. 3) Tedious to prepare. 4) Dangerous to hunt. 5) Low in nutrition.

Agrarian living more efficient use of land

250 sq miles feeds 25 H-Gs, vs 5.8 sq miles to feed 150 farmers
