20,000 BCE: (The World’s First Invention of Ceramic Technology in Southern China — Another Notable Development Marking the Onset of This Historical Period Being the Invention of Ceramic Technology in the Yangtze Region of Southern China Around Twenty Thousand Years Ago, Possibly a Response to Subsistence Challenges Occasioned by the Approaching End of the Glacial Maximum and the Need to Process New Kinds of Foods to Make Them More Easily Edible): Elsewhere in the world, another notable development marked the onset of this long historical period: the world’s first invention of ceramic technology, in the Yangtze region of southern China around twenty thousand years ago. Ehret raises the question of whether this invention might have been a response to the subsistence challenges occasioned by the approaching end of the Glacial Maximum — whether the people of the Yangtze valley, in making this invention, were responding to a climate-caused decline in the availability of previously common food sources and to the need to process new kinds of foods to make them more easily edible. The question is characteristically Ehret: it places technological innovation within its environmental and subsistence context, treating invention not as a flash of individual genius but as a collective response to material necessity. Ceramic technology — the ability to fire clay into durable vessels capable of cooking, storing, and processing food — would be independently invented multiple times in different parts of the world, including in Africa, where women are identified by the comparative cultural evidence as the primary inventors. But the earliest known instance was in southern China, and if Ehret’s hypothesis is correct, it was born not of abundance but of scarcity — a creative response to the narrowing of subsistence options that the climate of the late Glacial Maximum imposed. Innovation, as always, was the child of necessity.
