Origins of Agriculture; civilisation and climate

Why is the origin of agriculture important in human history?

It represents one of the most significant stages in human cultural evolution by transforming societies from mobile foragers into settled agricultural communities

When did agriculture first begin?

Agriculture began during the Early Holocene (11,700 years ago) after the last ice age

Why might climate have influenced the origin of agriculture?

The transition from the glacial period to the warmer Holocene created more favourable conditions for plant growth, making cultivation possible

Some major events that accompany the development of agriculture

Population growth, Urbanisation

What is foraging?

Subsistence strategy where humans obtain food by hunting, fishing and gathering wild plants rather than producing foodhaW

What is domestication?

The genetic modification of plants and animas through selective breeding = species adapted to human needs

Examples of early centres of agricultural origin

Fertile Crescent (Near East), Northern and Central China, Mesoamerica

Which crops are associated with major centres of origin?

Near East - Wheat and barley

Central China - Rica

Mesoamerica - Maize

What are ancient urban societies without independent agricultural origin? with examples

Society that developed complex urban systems but adopted agriculture form elsewhere eg. Egypt, Europe

What environmental conditions were common in early agricultural centres?

Seasonal climates

Presence of wild cereals or domesticable plants

Favourable climatic conditions during the Holocenehat W

What were the environmental conditions in the Levant?

Semi arid climate

Soils prone to erosion

Human land use had strong environmental impacts

What environmental conditions characterised early agriculture in China?

Monsoon rainfall

Thicker and more resilient soils

More stable agricultural landscapes

What is the agricultural demographic transition?

Theory suggesting that population growth increased food demand which encouraged the development and expansion of agriculture

Why might population growth encourage agriculture?

More people require more food, leading to greater reliance on cultivation and food production

Who were the Natufians?

A late Epipalaeolithic culture in the Fertile Crescent often associated with early sedentary communities before agriculture

Why are the Natufians important?

They provide evidence of semi-sedentary lifestyles and intensive wild feral harvesting which may have led to domestication

How did climate influence early agriculture in the Near East?

Changes in moisture levels and temperature influenced the distribution of wild cereals, affecting where agriculture could develop

What was the younger dryas?

Period of abrupt cooling and drying that disturbed early agricultural development 12,900 - 11,700

Why did agriculture expand after the younger dryas?

The start of the Holocene brought warmer and wetter conditions, allowing wild cereals to expand again
