Lajia
Lajia () is a Bronze Age archaeological site in the upper reaches of the Yellow River, on the border between the Chinese provinces of Gansu and Qinghai. As at other sites of the Qijia culture (c. 2300–1500 BCE), the people of Lajia had an agricultural economy based primarily on millet cultivation and sheep herding. They also kept pigs for use in ritual activities, including making oracle bones, and experimented with a high temperature-fired pottery described as proto-porcelain. The world's oldest known noodles were discovered at the site in 2005. A natural disaster buried the site and killed many of its inhabitants in around 1920 BCE, but archaeologists continue to debate the exact cause of the catastrophe. Background Lajia is associated with the Qijia culture, an archaeological culture of northwestern China dated to the late Neolithic and early Bronze Age periods (c. 2300–1500 BCE). Excavations at the site have unearthed various Qijia artifacts, including pottery, rings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noodle
Noodles are a type of food made from unleavened dough which is either rolled flat and cut, stretched, or extruded, into long strips or strings. Noodles are a staple food in many cultures and made into a variety of shapes. The most common noodles are those derived from either Chinese cuisine or Italian cuisine. Chinese noodles are known by a variety of different names, while Italian noodles are known as pasta. While long, thin strips may be the most common, many varieties of noodles are cut into waves, helices, tubes, strings, or shells, or folded over, or cut into other shapes. Noodles are usually cooked in boiling water, sometimes with cooking oil or salt added. They can also be steamed, pan-fried, deep-fried, or baked. Noodles are often served with an accompanying sauce or in a soup, the latter being known as noodle soup. Noodles can be refrigerated for short-term storage or dried and stored for future use. Etymology The word for noodles in English was borrowed in the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jishi Gorge Outburst Flood
The Jishi Gorge outburst flood was a natural disaster that occurred around 1920 BC in China. The water flow during the eruption was one of the largest fresh water flows to occur in our geologic epoch (Holocene) and caused large widespread flooding around the Yellow River, affecting everyone living in the river basin. The flood outbreak was triggered by the bursting of a dam caused by landslides after an earthquake. The flood is suggested to possibly be the disaster that gave rise to the Gun-Yu flood myth, which preceded the establishment of the Xia dynasty. The Lajia archaeological site, downstream of the Jishi Gorge, was first destroyed by the earthquake and later covered by sediments from the flood eruption. The course The Jishi Gorge (积石峡) leads the Yellow River from the river area around Xunhua in the west through the Jishi Mountain and further east to the river area around the Guanting Basin. An earthquake triggered landslides and rock avalanches that dammed the Yel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qijia Culture
The Qijia culture (2400 BC – 1600 BC) was an early Bronze Age culture distributed around the upper Yellow River region of Gansu (centered in Lanzhou) and eastern Qinghai, China. It is regarded as one of the earliest bronze cultures in China. The Qijia Culture is named after the Qijiaping Site (齐家坪) in Gansu Province. Prior to Qijia culture, in the same area there existed Majiayao culture that was also familiar with metalwork. At the end of the third millennium B.C., Qijia culture succeeded Majiayao culture at sites in three main geographic zones: Eastern Gansu, Middle Gansu, and Western Gansu/Eastern Qinghai. The Qijia culture benefited from the warm and humid climatic conditions from the Late Glacial to the Middle Holocene, which led to flourishing agricultural production and rapid population growth. These conditions changed with the aridification of the Late Holocene, provoking material and cultural decline. Research Johan Gunnar Andersson discovered the initial si ...

Neolithic
The Neolithic or New Stone Age (from Ancient Greek, Greek 'new' and 'stone') is an archaeological period, the final division of the Stone Age in Mesopotamia, Asia, Europe and Africa (c. 10,000 BCE to c. 2,000 BCE). It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the History of agriculture, introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of sedentism, settlement. The term 'Neolithic' was coined by John Lubbock, 1st Baron Avebury, Sir John Lubbock in 1865 as a refinement of the three-age system. The Neolithic began about 12,000 years ago, when farming appeared in the Epipalaeolithic Near East and Mesopotamia, and later in other parts of the world. It lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BCE), marked by the development ...

Millet
Millets () are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most millets belong to the tribe Paniceae. Millets are important crops in the Semi-arid climate, semiarid tropics of Asia and Africa, especially in India, Mali, Nigeria, and Niger, with 97% of production in Developing country, developing countries. The crop is favoured for its Agricultural productivity, productivity and short growing season under hot dry conditions. The millets are sometimes understood to include the widely cultivated sorghum; apart from that, pearl millet is the most commonly cultivated of the millets. Finger millet, proso millet, and foxtail millet are other important crop species. Millets may have been consumed by humans for about 7,000 years and potentially had "a pivotal role in the rise of multi-crop agriculture and settled farming societies". Etymology The word ''millet'' is derived via Old French ''millet, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for Chronological dating, determining the age of an object containing organic material by using the properties of carbon-14, radiocarbon, a radioactive Isotopes of carbon, isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Atmosphere of Earth, Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vegetation History And Archaeobotany
The International Work Group for Palaeoethnobotany (IWGP) is an informal, international collective of archaeobotanists, with the main goal of establishing and maintaining international communication and collaboration by a series of conferences. These conferences focus mainly, but not exclusively, on the study of plant macrofossils in order to reconstruct past subsistence, trade, construction, ritual, and the environment. Origins The idea of an international group focussed on human-plant interactions originated at the 7th International Congress of Prehistoric and Protohistoric Sciences in 1966, by the researchers Maria Hopf, Klaus-Dieter Jäger, Maria Follieri, Emanuel Opravil, Zdeněk Tempír, Árpád Patay, and Jane Renfrew, in discussion with Fatih Khafizovich Bakhteev, Moisej Markovič Jakubziner, and Willem van Zeist. The first meeting in 1968 consisted of 12 people and took place at Kačina, near Prague. The meeting was termed the Internationale Arbeitsgemeinschaft fü ...

Broomcorn Millet
''Panicum miliaceum'' is a grain crop with many common names, including proso millet, broomcorn millet, common millet, hog millet, Kashfi millet, red millet, and white millet. Archaeobotanical evidence suggests millet was first domesticated about 10,000 BP in Northern China. Major cultivated areas include Northern China, Himachal Pradesh of India, Nepal, Russia, Ukraine, Belarus, the Middle East, Turkey, Romania, and the Great Plains states of the United States. About are grown each year. The crop is notable both for its extremely short lifecycle, with some varieties producing grain only 60 days after planting, and its low water requirements, producing grain more efficiently per unit of moisture than any other grain species tested. The name "proso millet" comes from the pan-Slavic general and generic name for millet ( sh-Latn-Cyrl, separator=/, proso, просо, , , ). Proso millet is a relative of foxtail millet, pearl millet, maize, and sorghum within the grass subfamily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foxtail Millet
Foxtail millet, scientific name ''Setaria italica'' (synonym ''Panicum italicum'' L.), is an annual grass grown for human food. It is the second-most widely planted species of millet, and the most grown millet species in Asia. The oldest evidence of foxtail millet cultivation was found along the ancient course of the Yellow River in Cishan culture, Cishan, China, carbon dated to be from around 8,000 years before present. Foxtail millet has also been grown in India since antiquity. Other names for the species include dwarf setaria, foxtail bristle-grass, giant setaria, green foxtail, Italian millet, German millet, and Hungarian millet. Description Foxtail millet is an annual plant, annual Poaceae, grass with slim, vertical, leafy stems which can reach a height of . The seedhead is a dense, hairy panicle long.
