![]() ![]() In Mexico, squash cultivation began around 10,000 years ago, but corn ( maize) had to wait for natural genetic mutations to be selected for in its wild ancestor, teosinte. ![]() The world’s oldest known rice paddy fields, discovered in eastern China in 2007, reveal evidence of ancient cultivation techniques such as flood and fire control. The origins of rice and millet farming date to the same Neolithic period in China. Though the transition from wild harvesting was gradual, the switch from a nomadic to a settled way of life is marked by the appearance of early Neolithic villages with homes equipped with grinding stones for processing grain. Cereals were grown in Syria as long as 9,000 years ago, while figs ( Ficus carica) were cultivated even earlier prehistoric seedless fruits discovered in the Jordan Valley suggest fig trees were being planted some 11,300 years ago. The wild progenitors of crops including wheat ( Triticum aestivum), barley ( Hordeum vulgare), and peas ( Lathyrus oleraceus) are traced to the Near East region. But whatever the reasons for its independent origins, farming sowed the seeds for the modern age. ![]() Elsewhere, such as in East Asia, increased pressure on natural food resources may have forced people to find homegrown solutions. In the Near East, for example, it’s thought that climatic changes at the end of the last ice age brought seasonal conditions that favored annual plants like wild cereals. ![]() There was no single factor, or combination of factors, that led people to take up farming in different parts of the world. Out of agriculture, cities and civilizations grew, and because crops and animals could now be farmed to meet demand, the global population rocketed-from some five million people 10,000 years ago, to eight billion today. The Farming Revolution Taking root around 12,000 years ago, agriculture triggered such a change in society and the way in which people lived that its development has been dubbed the “ Neolithic Revolution.” Traditional hunter-gatherer lifestyles, followed by humans since their evolution, were swept aside in favor of permanent settlements and a reliable food supply. ![]()
