History of agriculture
Wild grains were collected and eaten from at least 20,000 BC. From around 9500 BC, the eight Neolithic founder crops – emmer wheat, einkorn wheat, hulled barley, peas, lentils, bitter vetch, chick peas, and flax – were cultivated in the Levant. Rye may have been cultivated earlier but this remains controversial. Rice was domesticated in China by 6200 BC with earliest known cultivation from 5700 BC, followed by mung, soy and azuki beans. Pigs were domesticated in Mesopotamia around 11,000 BC, followed by sheep between 11,000 BC and 9000 BC. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and Pakistan around 8500 BC. Sugarcane and some root vegetables were domesticated in New Guinea around 7000 BC. Sorghum was domesticated in the Sahel region of Africa by 5000 BC. In the Andes of South America, the potato was domesticated between 8000 BC and 5000 BC, along with beans, coca, llamas, alpacas, and guinea pigs. Bananas were cultivated and hybridized in the same period in Papua New Guinea. In Mesoamerica, wild teosinte was domesticated to maize by 4000 BC. Cotton was domesticated in Peru by 3600 BC. Camels were domesticated late, perhaps around 3000 BC.
Sedentism
The Jōmon culture in Japan, which was primarily a coastal culture, was sedentary from c. 12000 to 10000 BC, before the cultivation of rice at some sites in northern Kyushu. In northernmost Scandinavia, there are several early sedentary sites without evidence of agriculture or cattle breeding. They appeared from c. 5300-4500 BC and are all located optimally in the landscape for extraction of major ecosystem resources, e.g. the Lillberget Stone Age village site (c. 3900 BC), the Nyelv site (c. 5300 BC), and the Lake Inari site (c. 4500 BC). In northern Sweden the earliest indication of agriculture occurs at previously sedentary sites, and one example is the Bjurselet site used during the period c. 2700-1700 BC, famous for its large caches of long distance traded flint axes from Denmark and Scania (some 1300 km). The evidence of small-scale agriculture at that site can be seen from c. 2300 BC (burnt cereals of barley).
