wheat dating from 10,000 years ago are found in sites near Damascus, in<br />

northwestern Jordan, and on the Middle Euphrates River. Domesticated<br />

crops then spread south to Jericho in the Jordan Valley and northwest into<br />

southern Turkey.<br />

Although tradition places agriculture in the Middle East long before any<br />

parallel activity in Asia and the Americas, recent research suggests that people<br />

in South America, Mexico, and China may have domesticated plants<br />

long before the first signs <strong>of</strong> settled villages in these regions. Sediments in<br />

a cave called Diaotonghuan along China’s Yangtze River tell a story similar<br />

to that <strong>of</strong> Abu Hureyra in which wild rice was domesticated around the<br />

time <strong>of</strong> the Younger Dryas. Perhaps the abrupt climate changes <strong>of</strong> the<br />

Younger Dryas pushed semisettled people with declining resource bases<br />

into agricultural experimentation.<br />

Once the climate improved, groups adapted to growing grains had an<br />

advantage. Increasing reliance on domesticated crops spread across the<br />

region. <strong>The</strong> Natufian culture that flourished along the Mediterranean<br />

coast in modern Israel, Lebanon, and Syria from 9000 until 7500 bc was<br />

based on harvesting wild grain and herding goats and gazelles. Neither<br />

plants nor animals were fully domesticated when Natufian culture arose,<br />

yet by the end <strong>of</strong> the era, hunting accounted for just a fraction <strong>of</strong> the food<br />

supply.<br />

<strong>The</strong> regional population began to grow dramatically as domestication <strong>of</strong><br />

wheat and legumes increased food production. By about 7000 bc small<br />

farming villages were scattered throughout the region. Communities<br />

became increasingly sedentary as intensive exploitation <strong>of</strong> small areas discouraged<br />

continuing the annual cycle <strong>of</strong> moving among hunting camps<br />

scattered around a large territory. By about 6500 bc large towns <strong>of</strong> up to<br />

several thousand people became common. <strong>The</strong> seasonal rhythm <strong>of</strong> an<br />

annual trek to follow resources was over in the Middle East.<br />

Populations able to wrest more food from their environment could better<br />

survive periods <strong>of</strong> stress—like droughts or extreme cold. When bad<br />

times came, as they inevitably did, chance favored groups with experience<br />

tending gardens. <strong>The</strong>y better endured hardships and prospered during<br />

good times. And agricultural success upped the ante. Development <strong>of</strong><br />

more intensive and effective subsistence methods allowed human populations<br />

to grow beyond what could be supported by hunting and gathering.<br />

Eventually, communities came to depend on enhancing the productivity<br />

<strong>of</strong> natural ecosystems just to stay even, let alone grow. Early cultivators<br />

became tied to a place because mobility did not allow for tending and har-<br />

rivers <strong>of</strong> life
