116-466: Millets ( / ˈ m ɪ l ɪ t s / ) 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 semiarid tropics of Asia and Africa, especially in India , Mali , Nigeria , and Niger , with 97% of production in developing countries . The crop

232-499: A sod -forming perennial grass used in agriculture is Thinopyrum intermedium . Grasses are used as raw material for a multitude of purposes, including construction and in the composition of building materials such as cob , for insulation, in the manufacture of paper and board such as oriented structural straw board . Grass fiber can be used for making paper , biofuel production, nonwoven fabrics, and as replacement for glass fibers used in reinforced plastics. Bamboo scaffolding

348-666: A 4,000-year-old earthenware bowl containing well-preserved noodles at the Lajia archaeological site in north China; this is the oldest evidence of millet noodles in China. Palaeoethnobotanists have found evidence of the cultivation of millet in the Korean Peninsula dating to the Middle Jeulmun pottery period (around 3500–2000 BCE). Millet continued to be an important element in the intensive, multicropping agriculture of

464-581: A Circum Arabian Nomadic Pastoral Complex developed in the period from the climatic crisis of 6200 BC, partly as a result of an increasing emphasis in PPNB cultures upon domesticated animals, and a fusion with Harifian hunter gatherers in the Southern Levant, with affiliate connections with the cultures of Fayyum and the Eastern Desert of Egypt . Cultures practicing this lifestyle spread down

580-536: A culture contemporaneous with the Cishan and Xinglongwa cultures of about 6000–5000 BC, Neolithic cultures east of the Taihang Mountains , filling in an archaeological gap between the two Northern Chinese cultures. The total excavated area is more than 1,200 square yards (1,000 m ; 0.10 ha), and the collection of Neolithic findings at the site encompasses two phases. Between 3000 and 1900 BC,

696-447: A different enzyme in photosynthesis from C3 plants, and this is why it improves water efficiency. In southern Australia millet is used as a summer quality pasture, utilizing warm temperatures and summer storms. Millet is frost-sensitive and is sown after the frost period, once soil temperature has stabilised at 14 °C or higher. It is sown at a shallow depth. Millet grows rapidly and can be grazed 5–7 weeks after sowing, when it

812-515: A division into five periods. They also advanced the idea of a transitional stage between the PPNA and PPNB between 8800 and 8600 BC at sites like Jerf el Ahmar and Tell Aswad . Alluvial plains ( Sumer / Elam ). Low rainfall makes irrigation systems necessary. Ubaid culture originated from 6200 BC. The earliest evidence of Neolithic culture in northeast Africa was found in the archaeological sites of Bir Kiseiba and Nabta Playa in what

928-412: A dramatic increase in social inequality in most of the areas where it occurred; New Guinea being a notable exception. Possession of livestock allowed competition between households and resulted in inherited inequalities of wealth. Neolithic pastoralists who controlled large herds gradually acquired more livestock, and this made economic inequalities more pronounced. However, evidence of social inequality

1044-482: A food in parts of some countries, such as China , India , Burma and North Korea . People affected by gluten-related disorders , such as coeliac disease , non-celiac gluten sensitivity and wheat allergy sufferers, who need a gluten-free diet , can replace gluten -containing cereals in their diets with millet. Nevertheless, while millet does not contain gluten , its grains and flour may be contaminated with gluten -containing cereals. The following table shows

1160-551: A living tradition in small and extremely remote and inaccessible pockets of West Papua . Polished stone adze and axes are used in the present day (as of 2008 ) in areas where the availability of metal implements is limited. This is likely to cease altogether in the next few years as the older generation die off and steel blades and chainsaws prevail. In 2012, news was released about a new farming site discovered in Munam-ri , Goseong , Gangwon Province , South Korea , which may be

1276-608: A non-hierarchical system of organization existed is debatable, and there is no evidence that explicitly suggests that Neolithic societies functioned under any dominating class or individual, as was the case in the chiefdoms of the European Early Bronze Age . Possible exceptions to this include Iraq during the Ubaid period and England beginning in the Early Neolithic (4100–3000 BC). Theories to explain

1392-584: A photosynthetic pathway, linked to specialized Kranz leaf anatomy , which allows for increased water use efficiency , rendering them better adapted to hot, arid environments. The C3 grasses are referred to as "cool-season" grasses, while the C4 plants are considered "warm-season" grasses. Although the C4 species are all in the PACMAD clade (see diagram below), it seems that various forms of C4 have arisen some twenty or more times, in various subfamilies or genera. In

1508-637: A rarely used and not very useful concept in discussing Australian prehistory . During most of the Neolithic age of Eurasia , people lived in small tribes composed of multiple bands or lineages. There is little scientific evidence of developed social stratification in most Neolithic societies; social stratification is more associated with the later Bronze Age . Although some late Eurasian Neolithic societies formed complex stratified chiefdoms or even states , generally states evolved in Eurasia only with

1624-520: A significant portion of their ancestry from the Anatolian hunter-gatherers (AHG), suggesting that agriculture was adopted in site by these hunter-gatherers and not spread by demic diffusion into the region. The Neolithic 1 (PPNA) period began around 10,000 BC in the Levant . A temple area in southeastern Turkey at Göbekli Tepe , dated to around 9500 BC, may be regarded as the beginning of

1740-615: A similar nutrient content to other major cereals . The millets are closely related to sorghum and maize within the PACMAD clade of grasses, and more distantly to the cereals of the BOP clade such as wheat and barley . Bambusoideae (bamboos)  ( fescue , ryegrass ) Hordeum (barley) Triticum (wheat) Secale (rye) Oryza (rice) Pennisetum (fountaingrasses, pearl millet ) Millets Sorghum (sorghum) Zea (maize) The different species of millets are not all closely related. All are members of

1856-596: A smaller part of the vegetation in almost every other terrestrial habitat. Grass-dominated biomes are called grasslands. If only large, contiguous areas of grasslands are counted, these biomes cover 31% of the planet's land. Grasslands include pampas , steppes , and prairies . Grasses provide food to many grazing mammals, as well as to many species of butterflies and moths . Many types of animals eat grass as their main source of food, and are called graminivores – these include cattle , sheep , horses , rabbits and many invertebrates , such as grasshoppers and

1972-758: A term coined in the 1920s by the Australian archaeologist Vere Gordon Childe . One potential benefit of the development and increasing sophistication of farming technology was the possibility of producing surplus crop yields, in other words, food supplies in excess of the immediate needs of the community. Surpluses could be stored for later use, or possibly traded for other necessities or luxuries. Agricultural life afforded securities that nomadic life could not, and sedentary farming populations grew faster than nomadic. However, early farmers were also adversely affected in times of famine , such as may be caused by drought or pests . In instances where agriculture had become

2088-673: A variety developed in India from a natural-growing millet variety in Burkina Faso , doubled yields. This breed was selected for trials in Zimbabwe . From there it was taken to Namibia , where it was released in 1990 and enthusiastically adopted by farmers. 'Okashana 1' became the most popular variety in Namibia, the only non- Sahelian country where pearl millet—locally known as mahangu —is the dominant food staple for consumers. 'Okashana 1'

2204-910: A variety that include grasses that are related to modern rice and bamboo . Grasses have adapted to conditions in lush rain forests , dry deserts , cold mountains and even intertidal habitats , and are currently the most widespread plant type; grass is a valuable source of food and energy for all sorts of wildlife. A cladogram shows subfamilies and approximate species numbers in brackets: Chloridoideae (1600) Danthonioideae (300) Micrairoideae (200) Arundinoideae (50) Panicoideae (3250) Aristidoideae (350) Oryzoideae (110) Bambusoideae – bamboos (1450) Pooideae (3850) Puelioideae (11) Pharoideae (13) Anomochlooideae (4) Before 2005, fossil findings indicated that grasses evolved around 55 million years ago. Finds of grass-like phytoliths in Cretaceous dinosaur coprolites from

2320-426: Is 20–30 cm high. The highest feed value is from the young green leaf and shoots. The plant can quickly come to head, so it must be managed accordingly because as the plant matures, the value and palatability of feed reduces. The Japanese millets ( Echinochloa esculenta ) are considered the best for grazing and in particular Shirohie, a new variety of Japanese millet, is the best suited variety for grazing. This

2436-473: Is a grass used as a culinary herb for its citrus-like flavor and scent. Many species of grass are grown as pasture for foraging or as fodder for prescribed livestock feeds, particularly in the case of cattle , horses , and sheep . Such grasses may be cut and stored for later feeding, especially for the winter, in the form of bales of hay or straw , or in silos as silage . Straw (and sometimes hay) may also be used as bedding for animals. An example of

2552-550: Is a large body of evidence for fortified settlements at Linearbandkeramik sites along the Rhine , as at least some villages were fortified for some time with a palisade and an outer ditch. Settlements with palisades and weapon-traumatized bones, such as those found at the Talheim Death Pit , have been discovered and demonstrate that "...systematic violence between groups" and warfare was probably much more common during

2668-570: Is able to withstand typhoon-force winds that would break steel scaffolding. Larger bamboos and Arundo donax have stout culms that can be used in a manner similar to timber, Arundo is used to make reeds for woodwind instruments , and bamboo is used for innumerable implements. Phragmites australis (common reed) is important for thatching and wall construction of homes in Africa. Grasses are used in water treatment systems, in wetland conservation and land reclamation , and used to lessen

2784-468: Is also eaten sweet, boiled in water with apples added during the boiling process and honey added during the cooling process. Millet is the main ingredient in bánh đa kê, a Vietnamese sweet snack. It contains a layer of smashed millet and mungbean topped with sliced dried coconut meat wrapped in a crunchy rice cake. In parts of Africa it is mixed with milk and consumed as Brukina . In India, various alcoholic beverages are produced from millets. Millet

2900-421: Is also the base ingredient for the distilled liquor rakshi . In addition to being used for seed, millet is also used as a grazing forage crop. Instead of letting the plant reach maturity, it can be grazed by stock and is commonly used for sheep and cattle. Millet is a C4 plant, which means that it has good water-use efficiency and utilizes high temperature and is therefore a summer crop. A C4 plant uses

3016-563: Is better explained by lineal fission and polygyny. The shelter of early people changed dramatically from the Upper Paleolithic to the Neolithic era. In the Paleolithic, people did not normally live in permanent constructions. In the Neolithic, mud brick houses started appearing that were coated with plaster. The growth of agriculture made permanent houses far more common. At Çatalhöyük 9,000 years ago, doorways were made on

3132-628: Is due to a number of factors: it gives better regrowth and is later to mature compared to other Japanese millets; it is cheap – cost of seed is $ 2–$ 3 per kg; it is quick to establish, can be grazed early, and is suitable for both sheep and cattle. Compared to forage sorghum, which is grown as an alternative grazing forage, animals gain weight faster on millet, and it has better hay or silage potential, although it produces less dry matter. Lambs do better on millet compared to sorghum . Millet does not contain prussic acid , which can be in sorghum. Prussic acid poisons animals by inhibiting oxygen utilisation by

3248-436: Is favoured for its 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

3364-1004: Is for piecing together historical landscapes and weather patterns, considering other factors such as genetic material amount might also affect pollen size. Despite these challenges, new techniques in Fourier-Transform Infrared Spectroscopy (FT-IR) and improved statistical methods are now helping to better identify these similar-looking pollen types. Grasses are the primary plants used in lawns, which themselves derive from grazed grasslands in Europe. They also provide an important means of erosion control (e.g., along roadsides), especially on sloping land. Grass lawns are an important covering of playing surfaces in many sports, including football (soccer) , American football , tennis , golf , cricket , softball and baseball . Early Neolithic The Neolithic began about 12,000 years ago, when farming appeared in

3480-606: Is linked to crop improvement, since meiotic recombination is an important component of plant breeding . Unlike in animals, the specification of both male and female plant germlines occurs late in development during flowering. The transition from the sporophyte phase to the gametophyte state is initiated by meiotic entry. Grasses are, in human terms, perhaps the most economically important plant family. Their economic importance stems from several areas, including food production, industry, and lawns . They have been grown as food for domesticated animals for up to 6,000 years and

3596-540: Is now southwest Egypt. Domestication of sheep and goats reached Egypt from the Near East possibly as early as 6000 BC. Graeme Barker states "The first indisputable evidence for domestic plants and animals in the Nile valley is not until the early fifth millennium BC in northern Egypt and a thousand years later further south, in both cases as part of strategies that still relied heavily on fishing, hunting, and

3712-431: Is over 65 percent (see mahangu ). Other countries in Africa where millets are a significant food source include Ethiopia , Nigeria and Uganda . Millet is also an important food item for the population living in the drier parts of many other countries, especially in eastern and central Africa, and in the northern coastal countries of western Africa. In developing countries outside Africa, millet has local significance as

3828-666: Is required. Per capita consumption of millets as food varies in different parts of the world, with consumption being the highest in Western Africa. In the Sahel region, millet is estimated to account for about 35 percent of total cereal food consumption in Burkina Faso , Chad and the Gambia . In Mali and Senegal , millets constitute roughly 40 percent of total cereal food consumption per capita, while in Niger and arid Namibia it

3944-1024: Is still disputed, as settlements such as Çatalhöyük reveal a lack of difference in the size of homes and burial sites, suggesting a more egalitarian society with no evidence of the concept of capital, although some homes do appear slightly larger or more elaborately decorated than others. Families and households were still largely independent economically, and the household was probably the center of life. However, excavations in Central Europe have revealed that early Neolithic Linear Ceramic cultures (" Linearbandkeramik ") were building large arrangements of circular ditches between 4800 and 4600 BC. These structures (and their later counterparts such as causewayed enclosures , burial mounds , and henge ) required considerable time and labour to construct, which suggests that some influential individuals were able to organise and direct human labour – though non-hierarchical and voluntary work remain possibilities. There

4060-710: Is taken to overlap with the Pre-Pottery Neolithic A (PPNA) of 10,200–8800 BC. As the Natufians had become dependent on wild cereals in their diet, and a sedentary way of life had begun among them, the climatic changes associated with the Younger Dryas (about 10,000 BC) are thought to have forced people to develop farming. The founder crops of the Fertile Crescent were wheat , lentil , pea , chickpeas , bitter vetch, and flax. Among

4176-454: The Aristida genus for example, one species ( A. longifolia ) is C3 but the approximately 300 other species are C4. As another example, the whole tribe of Andropogoneae , which includes maize , sorghum , sugar cane , " Job's tears ", and bluestem grasses , is C4. Around 46 percent of grass species are C4 plants. The name Poaceae was given by John Hendley Barnhart in 1895, based on

4292-775: The Albian stage of the Early Cretaceous approximately 113–100 million years ago, which were found to belong to primitive lineages within Poaceae, similar in position to the Anomochlooideae. These are currently the oldest known grass fossils. The relationships among the three subfamilies Bambusoideae, Oryzoideae and Pooideae in the BOP clade have been resolved: Bambusoideae and Pooideae are more closely related to each other than to Oryzoideae. This separation occurred within

Additional food uses of sugarcane include sprouted grain , shoots , and rhizomes , and in drink they include sugarcane juice and plant milk , as well as rum , beer , whisky , and vodka . Bamboo shoots are used in numerous Asian dishes and broths, and are available in supermarkets in various sliced forms, in both fresh, fermented and canned versions. Lemongrass

4524-554: The Bronze Age began about 3500 BC, replacing the Neolithic cultures. Around 10,000 BC the first fully developed Neolithic cultures belonging to the phase Pre-Pottery Neolithic A (PPNA) appeared in the Fertile Crescent. Around 10,700–9400 BC a settlement was established in Tell Qaramel , 10 miles (16 km) north of Aleppo . The settlement included two temples dating to 9650 BC. Around 9000 BC during

4640-458: The Cenozoic contributed to the spread of grasses. Without large grazers, fire-cleared areas are quickly colonized by grasses, and with enough rain, tree seedlings. Trees eventually outcompete most grasses. Trampling grazers kill seedling trees but not grasses. Sexual reproduction and meiosis have been studied in rice , maize , wheat and barley . Meiosis research in these crop species

4756-554: The Early Neolithic of China. Some of the earliest evidence of millet cultivation in China was found at Cishan (north), where proso millet husk phytoliths and biomolecular components have been identified around 10,300–8,700 years ago in storage pits along with remains of pit-houses, pottery, and stone tools related to millet cultivation. Evidence at Cishan for foxtail millet dates back to around 8,700 years ago. Noodles made from these two varieties of millet were found under

It lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BC), marked by the development of metallurgy , leading up to the Bronze Age and Iron Age . In other places, the Neolithic followed the Mesolithic (Middle Stone Age) and then lasted until later. In Ancient Egypt ,

The start of Neolithic 1 overlaps the Tahunian and Heavy Neolithic periods to some degree. The major advance of Neolithic 1 was true farming. In the proto-Neolithic Natufian cultures, wild cereals were harvested, and perhaps early seed selection and re-seeding occurred. The grain

5104-559: The Longshan culture existed in the middle and lower Yellow River valley areas of northern China. Towards the end of the 3rd millennium BC, the population decreased sharply in most of the region and many of the larger centres were abandoned, possibly due to environmental change linked to the end of the Holocene Climatic Optimum . The 'Neolithic' (defined in this paragraph as using polished stone implements) remains

Early development occurred in the Levant (e.g. Pre-Pottery Neolithic A and Pre-Pottery Neolithic B ) and from there spread eastwards and westwards. Neolithic cultures are also attested in southeastern Anatolia and northern Mesopotamia by around 8000 BC. Anatolian Neolithic farmers derived

5336-866: The Mumun pottery period (about 1500–300 BCE) in Korea. Millets and their wild ancestors, such as barnyard grass and panic grass , were also cultivated in Japan during the Jōmon period sometime after 4000 BCE. Chinese myths attribute the domestication of millet to Shennong , a legendary Emperor of China, and Hou Ji , whose name means Lord Millet. Little millet ( Panicum sumatrense ) is believed to have been domesticated around 5000 BCE in Indian subcontinent and Kodo millet ( Paspalum scrobiculatum ) around 3700 BCE, also in Indian subcontinent. Various millets have been mentioned in some of

By then distinctive cultures emerged, with pottery like the Halafian (Turkey, Syria, Northern Mesopotamia) and Ubaid (Southern Mesopotamia). This period has been further divided into PNA (Pottery Neolithic A) and PNB (Pottery Neolithic B) at some sites. The Chalcolithic (Stone-Bronze) period began about 4500 BC, then

Through archaeology, historical linguistics and archaeogenetics, they conventionally have been identified with

5684-467: The Sahara in western Africa. Millets, however, do respond to high fertility and moisture. On a per-hectare basis, millet grain production can be 2 to 4 times higher with use of irrigation and soil supplements. Improved breeds of millet with enhanced disease resistance can significantly increase farm yield. There has been cooperation between poor countries to improve millet yields. For example, 'Okashana 1',

Pearl millet is one of the two major crops in the semiarid, impoverished, less fertile agriculture regions of Africa and southeast Asia. Millets are not only adapted to poor, dry infertile soils, but they are also more reliable under these conditions than most other grain crops.

With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family , following the Asteraceae , Orchidaceae , Fabaceae and Rubiaceae . The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize , wheat , rice , oats , barley , and millet for people and as feed for meat-producing animals . They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of

Among the earliest cultural complexes of this area are the Sesklo culture in Thessaly, which later expanded in the Balkans giving rise to Starčevo-Körös (Cris), Linearbandkeramik , and Vinča . Through a combination of cultural diffusion and migration of peoples , the Neolithic traditions spread west and northwards to reach northwestern Europe by around 4500 BC. The Vinča culture may have created

During the Early Neolithic period, farming was introduced by Europeans and was subsequently adopted by the locals. During the Middle Neolithic period, an influx of ancestry from the Levant appeared in Northwestern Africa, coinciding with

6844-542: The Neolithic appeared everywhere in the same order: the earliest farming societies in the Near East did not use pottery. In other parts of the world, such as Africa , South Asia and Southeast Asia , independent domestication events led to their own regionally distinctive Neolithic cultures, which arose completely independently of those in Europe and Southwest Asia . Early Japanese societies and other East Asian cultures used pottery before developing agriculture. In

It was surrounded by a stone wall, may have contained a population of up to 2,000–3,000 people, and contained a massive stone tower. Around 6400 BC the Halaf culture appeared in Syria and Northern Mesopotamia. In 1981, a team of researchers from the Maison de l'Orient et de la Méditerranée , including Jacques Cauvin and Oliver Aurenche, divided Near East Neolithic chronology into ten periods (0 to 9) based on social, economic and cultural characteristics. In 2002, Danielle Stordeur and Frédéric Abbès advanced this system with

Grasses have stems that are hollow except at the nodes and narrow alternate leaves borne in two ranks. The lower part of each leaf encloses the stem, forming a leaf-sheath. The leaf grows from the base of the blade, an adaptation allowing it to cope with frequent grazing. Grasslands such as savannah and prairie where grasses are dominant are estimated to constitute 40.5% of

In Mesoamerica , a similar set of events (i.e., crop domestication and sedentary lifestyles) occurred by around 4500 BC in South America, but possibly as early as 11,000–10,000 BC. These cultures are usually not referred to as belonging to the Neolithic; in North America, different terms are used such as Formative stage instead of mid-late Neolithic, Archaic Era instead of Early Neolithic, and Paleo-Indian for

The flowers are usually hermaphroditic — maize being an important exception—and mainly anemophilous or wind-pollinated, although insects occasionally play a role. The perianth is reduced to two scales, called lodicules , that expand and contract to spread

8120-423: The bow and arrow and ceramic pottery were also introduced. In later periods cities of considerable size developed, and some metallurgy by 700 BC. Australia, in contrast to New Guinea , has generally been held not to have had a Neolithic period, with a hunter-gatherer lifestyle continuing until the arrival of Europeans. This view can be challenged in terms of the definition of agriculture, but "Neolithic" remains

8236-450: The caterpillars of many brown butterflies . Grasses are also eaten by omnivorous or even occasionally by primarily carnivorous animals. Grasses dominate certain biomes , especially temperate grasslands , because many species are adapted to grazing and fire. Grasses are unusual in that the meristem is near the bottom of the plant; hence, grasses can quickly recover from cropping at the top. The evolution of large grazing animals in

8352-444: The cells and is transported in the blood around the body — ultimately the animal will die from asphyxia . There is no need for additional feed supplements such as sulfur or salt blocks with millet. The rapid growth of millet as a grazing crop allows flexibility in its use. Farmers can wait until sufficient late spring / summer moisture is present and then make use of it. It is ideally suited to irrigation where livestock finishing

8468-522: The cultivation of millets was of greater prevalence in prehistory than rice , especially in northern China and Korea. The cultivation of common millet as the earliest dry crop in East Asia has been attributed to its resistance to drought, and this has been suggested to have aided its spread. Asian varieties of millet made their way from China to the Black Sea region of Europe by 5000 BCE. Millet

8584-504: The dead, which were plastered with mud to make facial features. The rest of the corpse could have been left outside the settlement to decay until only the bones were left, then the bones were buried inside the settlement underneath the floor or between houses. Work at the site of 'Ain Ghazal in Jordan has indicated a later Pre-Pottery Neolithic C period. Juris Zarins has proposed that

8700-542: The earliest farmland known to date in east Asia. "No remains of an agricultural field from the Neolithic period have been found in any East Asian country before, the institute said, adding that the discovery reveals that the history of agricultural cultivation at least began during the period on the Korean Peninsula ". The farm was dated between 3600 and 3000 BC. Pottery, stone projectile points, and possible houses were also found. "In 2002, researchers discovered prehistoric earthenware , jade earrings, among other items in

8816-573: The earliest system of writing, the Vinča signs , though archaeologist Shan Winn believes they most likely represented pictograms and ideograms rather than a truly developed form of writing. The Cucuteni-Trypillian culture built enormous settlements in Romania, Moldova and Ukraine from 5300 to 2300 BC. The megalithic temple complexes of Ġgantija on the Mediterranean island of Gozo (in

8932-446: The enclosures also suggest grain and meat storage. The Neolithic 2 (PPNB) began around 8800 BC according to the ASPRO chronology in the Levant ( Jericho , West Bank). As with the PPNA dates, there are two versions from the same laboratories noted above. This system of terminology, however, is not convenient for southeast Anatolia and settlements of the middle Anatolia basin. A settlement of 3,000 inhabitants called 'Ain Ghazal

9048-835: The erosional impact of urban storm water runoff. Pollen morphology, particularly in the Poaceae family, is key to figuring out their evolutionary relationships and how environments have changed over time . Grass pollen grains, however, often look the same, making it hard to use them for detailed climate or environmental reconstructions. Grass pollen has a single pore and can vary a lot in size, from about 20 to over 100 micrometers, and this size difference has been looked into for clues about past habitats, to tell apart domesticated grasses from wild ones, and to indicate various biological features like how they perform photosynthesis , their breeding systems, and genetic complexity. Yet, there's ongoing debate about how effective pollen size

9164-467: The family Poaceae (the grasses), but they belong to different tribes and subfamilies. Commonly cultivated millets are: Eragrostideae tribe in the subfamily Chloridoideae : Paniceae tribe in the subfamily Panicoideae : Andropogoneae tribe, also in the subfamily Panicoideae : Specialized archaeologists called palaeoethnobotanists , relying on data such as the relative abundance of charred grains found in archaeological sites, hypothesize that

9280-575: The first cultivated crop and mark the invention of the technology of farming. This occurred centuries before the first cultivation of grains. Settlements became more permanent, with circular houses, much like those of the Natufians, with single rooms. However, these houses were for the first time made of mudbrick . The settlement had a surrounding stone wall and perhaps a stone tower (as in Jericho). The wall served as protection from nearby groups, as protection from floods, or to keep animals penned. Some of

9396-505: The first form of African food production was mobile pastoralism , or ways of life centered on the herding and management of livestock. The term "Pastoral Neolithic" is used most often by archaeologists to describe early pastoralist periods in the Sahara , as well as in eastern Africa . The Savanna Pastoral Neolithic or SPN (formerly known as the Stone Bowl Culture ) is a collection of ancient societies that appeared in

9512-469: The full list of Poaceae genera . The grass family is one of the most widely distributed and abundant groups of plants on Earth . Grasses are found on every continent, including Antarctica . The Antarctic hair grass, Deschampsia antarctica is one of only two plant species native to the western Antarctic Peninsula . Grasses are the dominant vegetation in many habitats, including grassland , salt-marsh , reedswamp and steppes . They also occur as

9628-512: The gathering of wild plants" and suggests that these subsistence changes were not due to farmers migrating from the Near East but was an indigenous development, with cereals either indigenous or obtained through exchange. Other scholars argue that the primary stimulus for agriculture and domesticated animals (as well as mud-brick architecture and other Neolithic cultural features) in Egypt was from

9744-478: The grains of grasses such as wheat , rice, maize (corn) and barley have been the most important human food crops . Grasses are also used in the manufacture of thatch , paper , fuel , clothing , insulation , timber for fencing , furniture , scaffolding and construction materials, floor matting , sports turf and baskets . Of all crops grown, 70% are grasses. Agricultural grasses grown for their edible seeds are called cereals or grains (although

9860-463: The land area of the Earth , excluding Greenland and Antarctica . Grasses are also an important part of the vegetation in many other habitats, including wetlands , forests and tundra . Though they are commonly called "grasses", groups such as the seagrasses , rushes and sedges fall outside this family. The rushes and sedges are related to the Poaceae, being members of the order Poales , but

9976-453: The latest Cretaceous ( Maastrichtian ) aged Lameta Formation of India have pushed this date back to 66 million years ago. In 2011, fossils from the same deposit were found to belong to the modern rice tribe Oryzeae , suggesting substantial diversification of major lineages by this time. In 2018, a study described grass microfossils extracted from the teeth of the hadrosauroid dinosaur Equijubus normani from northern China, dating to

10092-572: The latter term, when used agriculturally, refers to both cereals and similar seeds of other plant species, such as buckwheat and legumes ). Three cereals—rice, wheat, and maize (corn)—provide more than half of all calories consumed by humans. Cereals constitute the major source of carbohydrates for humans and perhaps the major source of protein; these include rice (in southern and eastern Asia ), maize (in Central and South America ), and wheat and barley (in Europe , northern Asia and

10208-463: The leaves are attached. Grass leaves are nearly always alternate and distichous (in one plane), and have parallel veins. Each leaf is differentiated into a lower sheath hugging the stem and a blade with entire (i.e., smooth) margins. The leaf blades of many grasses are hardened with silica phytoliths , which discourage grazing animals; some, such as sword grass , are sharp enough to cut human skin. A membranous appendage or fringe of hairs called

10324-469: The lemma and palea; these are generally interpreted to be modified sepals. The fruit of grasses is a caryopsis , in which the seed coat is fused to the fruit wall. A tiller is a leafy shoot other than the first shoot produced from the seed. Grass blades grow at the base of the blade and not from elongated stem tips. This low growth point evolved in response to grazing animals and allows grasses to be grazed or mown regularly without severe damage to

10440-745: The local staple, hand-rolled (that is, made without a rolling pin) flat bread ( rotla in Gujarati, bhakri in Marathi, or roti in other languages). Another cereal grain popularly used in rural areas and by poor people to consume as a staple in the form of roti . Other millets such as ragi (finger millet) in Karnataka , naachanie in Maharashtra , or kezhvaragu in Tamil, "ragulu" in Telugu, with

10556-551: The next 1,500 years. Populations began to rise after 3500 BC, with further dips and rises occurring between 3000 and 2500 BC but varying in date between regions. Around this time is the Neolithic decline , when populations collapsed across most of Europe, possibly caused by climatic conditions, plague, or mass migration. Settled life, encompassing the transition from foraging to farming and pastoralism, began in South Asia in

10672-440: The next two thousand years, but in some parts of Northwest Europe it is much later, lasting just under 3,000 years from c. 4500 BC–1700 BC. Recent advances in archaeogenetics have confirmed that the spread of agriculture from the Middle East to Europe was strongly correlated with the migration of early farmers from Anatolia about 9,000 years ago, and was not just a cultural exchange. Anthropomorphic figurines have been found in

10788-443: The nutrient content of millet compared to major staple foods in a raw form. Grasses Gramineae  Juss. Poaceae ( / p oʊ ˈ eɪ s i . iː , - s i aɪ / poh- AY -see-e(y)e ), also called Gramineae ( / ɡ r ə ˈ m ɪ n i . iː , - n i aɪ / grə- MIN -ee-e(y)e ), is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses . It includes

10904-502: The other major crop domesticated were rice, millet, maize (corn), and potatoes. Crops were usually domesticated in a single location and ancestral wild species are still found. [1] Early Neolithic farming was limited to a narrow range of plants, both wild and domesticated, which included einkorn wheat , millet and spelt , and the keeping of dogs . By about 8000 BC, it included domesticated sheep and goats , cattle and pigs . Not all of these cultural elements characteristic of

11020-700: The period. This site was developed by nomadic hunter-gatherer tribes, as evidenced by the lack of permanent housing in the vicinity, and may be the oldest known human-made place of worship. At least seven stone circles, covering 25 acres (10 ha), contain limestone pillars carved with animals, insects, and birds. Stone tools were used by perhaps as many as hundreds of people to create the pillars, which might have supported roofs. Other early PPNA sites dating to around 9500–9000 BC have been found in Palestine , notably in Tell es-Sultan (ancient Jericho ) and Gilgal in

11136-400: The plant. Three general classifications of growth habit present in grasses: bunch-type (also called caespitose), stoloniferous , and rhizomatous . The success of the grasses lies in part in their morphology and growth processes and in part in their physiological diversity. There are both C3 and C4 grasses, referring to the photosynthetic pathway for carbon fixation. The C4 grasses have

11252-628: The popular ragi rotti and Ragi mudde is a popular meal in Karnataka. Ragi, as it is popularly known, is dark in color like rye, but rougher in texture. Millet porridge is a traditional food in Russian , German , and Chinese cuisines. In Russia, it is eaten sweet (with milk and sugar added at the end of the cooking process) or savoury with meat or vegetable stews. In China, it is eaten without milk or sugar, frequently with beans, sweet potato , and/or various types of squash . In Germany, it

11368-483: The preceding period. The Formative stage is equivalent to the Neolithic Revolution period in Europe, Asia, and Africa. In the southwestern United States it occurred from 500 to 1200 AD when there was a dramatic increase in population and development of large villages supported by agriculture based on dryland farming of corn (maize), and later, beans, squash, and domesticated turkeys. During this period

11484-454: The predominant way of life, the sensitivity to these shortages could be particularly acute, affecting agrarian populations to an extent that otherwise may not have been routinely experienced by prior hunter-gatherer communities. Nevertheless, agrarian communities generally proved successful, and their growth and the expansion of territory under cultivation continued. Another significant change undergone by many of these newly agrarian communities

11600-417: The previous megalithic temples. It is presumed the population arrived from Sicily because of the similarity of Maltese dolmens to some small constructions found there. With some exceptions, population levels rose rapidly at the beginning of the Neolithic until they reached the carrying capacity . This was followed by a population crash of "enormous magnitude" after 5000 BC, with levels remaining low during

11716-496: The previous reliance on an essentially nomadic hunter-gatherer subsistence technique or pastoral transhumance was at first supplemented, and then increasingly replaced by, a reliance upon the foods produced from cultivated lands. These developments are also believed to have greatly encouraged the growth of settlements, since it may be supposed that the increased need to spend more time and labor in tending crop fields required more localized dwellings. This trend would continue into

11832-422: The region of Balochistan , Pakistan, around 7,000 BC. At the site of Mehrgarh , Balochistan, presence can be documented of the domestication of wheat and barley, rapidly followed by that of goats, sheep, and cattle. In April 2006, it was announced in the scientific journal Nature that the oldest (and first Early Neolithic ) evidence for the drilling of teeth in vivo (using bow drills and flint tips)

11948-629: The relatively short time span of about 4 million years. According to Lester Charles King , the spread of grasses in the Late Cenozoic would have changed patterns of hillslope evolution favouring slopes that are convex upslope and concave downslope and lacking a free face were common. King argued that this was the result of more slowly acting surface wash caused by carpets of grass which in turn would have resulted in relatively more soil creep . There are about 12,000 grass species in about 771 genera that are classified into 12 subfamilies. See

12064-692: The rise of metallurgy, and most Neolithic societies on the whole were relatively simple and egalitarian. Beyond Eurasia, however, states were formed during the local Neolithic in three areas, namely in the Preceramic Andes with the Caral-Supe Civilization , Formative Mesoamerica and Ancient Hawaiʻi . However, most Neolithic societies were noticeably more hierarchical than the Upper Paleolithic cultures that preceded them and hunter-gatherer cultures in general. The domestication of large animals (c. 8000 BC) resulted in

12180-532: The rise of multi-crop agriculture and settled farming societies". Etymologically, millet is a term derived from Latin millium , the Latin name for these plants. In ancient Egyptian millet was called besha or beṭ-t , in Coptic ⲃϣⲧⲉ (bēshte). Millets are small-grained, annual, warm-weather cereals belonging to the grass family. They are highly tolerant of drought and other extreme weather conditions and have

12296-771: The roof, with ladders positioned both on the inside and outside of the houses. Stilt-house settlements were common in the Alpine and Pianura Padana ( Terramare ) region. Remains have been found in the Ljubljana Marsh in Slovenia and at the Mondsee and Attersee lakes in Upper Austria , for example. A significant and far-reaching shift in human subsistence and lifestyle was to be brought about in areas where crop farming and cultivation were first developed:

12412-412: The seagrasses are members of the order Alismatales . However, all of them belong to the monocot group of plants. Grasses may be annual or perennial herbs , generally with the following characteristics (the image gallery can be used for reference): The stems of grasses, called culms , are usually cylindrical (more rarely flattened, but not 3-angled) and are hollow, plugged at the nodes , where

12528-740: The sole exception is China , number three in global production, at 2.7 million tonnes. Millets are major food sources in arid and semiarid regions of the world, and feature in the traditional cuisine of many others. In western India, sorghum (called jowar , jola , dzonnalu , jwaarie , or jondhahlaa in Gujarati , Kannada , Telugu , Hindi and Marathi languages, respectively; mutthaari , kora , or panjappullu in Malayalam ; or cholam in Tamil ) has been commonly used with millet flour (called jowari in western India) for hundreds of years to make

12644-466: The tribe Poeae described in 1814 by Robert Brown , and the type genus Poa described in 1753 by Carl Linnaeus . The term is derived from the Ancient Greek πόα (póa, "fodder") . Grasses include some of the most versatile plant life-forms . They became widespread toward the end of the Cretaceous period, and fossilized dinosaur dung ( coprolites ) have been found containing phytoliths of

12760-577: Was domesticated in the Sahel region of West Africa from Pennisetum violaceum . Early archaeological evidence in Africa includes finds at Birimi in northern Ghana (1740 cal BC ) and Dhar Tichitt in Mauritania (1936–1683 cal BC) and the lower Tilemsi valley in Mali (2500 to 2000 cal BC). Studies of isozymes suggest domestication took place north east of the Senegal River in the far west of

12876-813: Was found in Mehrgarh. In South India, the Neolithic began by 6500 BC and lasted until around 1400 BC when the Megalithic transition period began. South Indian Neolithic is characterized by Ash mounds from 2500 BC in Karnataka region, expanded later to Tamil Nadu . In East Asia, the earliest sites include the Nanzhuangtou culture around 9500–9000 BC, Pengtoushan culture around 7500–6100 BC, and Peiligang culture around 7000–5000 BC. The prehistoric Beifudi site near Yixian in Hebei Province, China, contains relics of

12992-409: Was found in the outskirts of Amman , Jordan . Considered to be one of the largest prehistoric settlements in the Near East , it was continuously inhabited from approximately 7250 BC to approximately 5000 BC. Settlements have rectangular mud-brick houses where the family lived together in single or multiple rooms. Burial findings suggest an ancestor cult where people preserved skulls of

13108-455: Was ground into flour. Emmer wheat was domesticated, and animals were herded and domesticated ( animal husbandry and selective breeding ). In 2006, remains of figs were discovered in a house in Jericho dated to 9400 BC. The figs are of a mutant variety that cannot be pollinated by insects, and therefore the trees can only reproduce from cuttings. This evidence suggests that figs were

13224-645: Was growing wild in Greece as early as 3000 BCE, and bulk storage containers for millet have been found from the Late Bronze Age in Macedonia and northern Greece. Hesiod describes that "the beards grow round the millet, which men sow in summer." And millet is listed along with wheat in the third century BCE by Theophrastus in his "Enquiry into Plants". Proso millet ( Panicum miliaceum ) and foxtail millet ( Setaria italica ) were important crops beginning in

13340-402: Was one of diet . Pre-agrarian diets varied by region, season, available local plant and animal resources and degree of pastoralism and hunting. Post-agrarian diet was restricted to a limited package of successfully cultivated cereal grains, plants and to a variable extent domesticated animals and animal products. Supplementation of diet by hunting and gathering was to variable degrees precluded by

13456-482: Was then introduced to Chad . The breed has significantly enhanced yields in Mauritania and Benin . In 2022, global production of millet was 30.9 million tonnes . India is the top millet producer worldwide, with 11.8 million tonnes grown annually – some 38% of the world total and nearly triple its nearest rival. Eight of the remaining nine nations in the top 10 producers are in Africa, ranging from Niger (at 3.7 million tonnes) to Chad (0.7 million tonnes);
