Human history
Rise of agriculture

Beginning around 10,000 BCE, the Neolithic Revolution marked the development of agriculture, which fundamentally changed the human lifestyle. Agriculture began independently in different parts of the globe, and included a diverse range of taxa, in at least 11 separate centers of origin. Cereal crop cultivation and animal domestication had occurred in Mesopotamia by at least 8500 BCE in the form of wheat, barley, sheep, and goats. The Yangtze River Valley in China domesticated rice around 8000–7000 BCE; the Yellow River Valley may have cultivated millet by 7000 BCE. Pigs were the most important domesticated animal in early China. People in Africa's Sahara cultivated sorghum and several other crops between 8000 and 5000 BCE, while other agricultural centers arose in the Ethiopian Highlands and the West African rainforests. In the Indus River Valley, crops were cultivated by 7000 BCE and cattle were domesticated by 6500 BCE. In the Americas, squash was cultivated by at least 8500 BCE in South America, and domesticated arrowroot appeared in Central America by 7800 BCE. Potatoes were first cultivated in the Andes of South America, where the llama was also domesticated. It is likely that women played a central role in plant domestication throughout these developments.
