Rice, Ayurveda, and the Classical Mediterranean Table
Rice, the staple that today feeds more people than any other crop, was domesticated from the wild grass Oryza rufipogon in eastern Asia. Genetic and archaeobotanical evidence points to the middle and lower Yangtze River valley, in present-day China, as the primary center of domestication for Oryza sativa japonica, with cultivation underway by around 7000 BCE and fully domesticated rice appearing by roughly 4000 BCE. A second major lineage, Oryza sativa indica, was long thought to have been domesticated independently on the Indian subcontinent, in the Ganges plain, though more recent genetic research suggests indica rice may instead derive from early hybridization between japonica rice, introduced from China, and local wild rice populations in South Asia, a question that remains actively debated among specialists. From these centers, rice cultivation spread outward along multiple routes: southward and eastward into Southeast Asia, northward into the Korean peninsula and, by around 300 BCE, into Japan, where it transformed the Yayoi-period diet and economy.
