The first known Pottery in the World

: "That end of the Ice Age was accompanied by the first of the two most decisive changes in Japanese history: the invention of pottery. In the usual experience of archeologists, inventions flow from mainlands to islands, and small peripheral societies aren't supposed to contribute revolutionary advances to the rest of the world. It therefore astonished archeologists to discover that the world's oldest known pottery was made in Japan 12,700 years ago. For the first time in human experience, people had watertight containers readily available in any desired shape. With their new ability to boil or steam food, they gained access to abundant resources that had previously been difficult to use: leafy vegetables, which would burn or dry out if cooked on an open fire; shellfish, which could now be opened easily; and toxic foods like acorns, which could now have their toxins boiled out. Soft-boiled foods could be fed to small children, permitting earlier weaning and more closely spaced babies. Toothless old people, the repositories of information in a preliterate society, could now be fed and live longer. All those momentous consequences of pottery triggered a population explosion, causing Japan's population to climb from an estimated few thousand to a quarter of a million. The prejudice that islanders are supposed to learn from superior continentals wasn't the sole reason that record-breaking Japanese pottery caused such a shock. In addition, those first Japanese potters were clearly hunter-gatherers, which also violated established views. Usually only sedentary societies own pottery: what nomad wants to carry heavy, fragile pots, as well as weapons and the baby, whenever time comes to shift camps. Most sedentary societies elsewhere in the world arose only with the adoption of agriculture. But the Japanese environment is so productive that people could settle down and make pottery while still living by hunting and gathering. Pottery helped those Japanese hunter-gatherers exploit their environment rich food resources more than 10,000 years before intensive agriculture reached Japan."
