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.
Franchthi Cave
The cave also contains some of the earliest evidence for agriculture in Greece. Around 7,000 BCE the remains of domesticated plants and animals are found among the usual wild plant and animal species hunted and gathered during the Mesolithic, suggesting that either the inhabitants of Franchthi had begun to practice agriculture or were trading for seeds and meat with the Neolithic people who had recently arrived from the Near East. There has been some debate about whether agriculture developed locally in Greece, or was introduced by colonists. It is now generally believed that emigrants from the Pre-Pottery Neolithic B cultures of the Near East arrived by boat at the beginning of the seventh millennium BCE to settle Greece(c.6,900 BCE), introducing agriculture. For some time the evidence from Franchthi was used as an example in support of locally developed agriculture, but more detailed study of the remains has demonstrated that the evidence supports the foreign introduction of domesticated plants and animals. The Mesolithic hunter gatherers of Greece rapidly adopted the methods introduced to them by Neolithic colonists, including at Franchthi Cave. During the Neolithic main occupancy of the cave shifted to an area outside the entrance, called the Paralia (the seaside), where terracing walls for growing crops were built. It is believed the inhabitants also occupied a village below the Paralia, which is now submerged beneath the sea. Several anthropomorphic and zoomorphic figurines have been recovered at Franchthi from the Neolithic era, and it has been suggested that the site may have served as a workshop for making cockle-shell beads to trade with inland communities during the Early Neolithic. The cave and the Paralia were abandoned around 3,000 BCE.
