The '''Neolithic Revolution''', also known as the '''First Agricultural Revolution''', was the wide-scale transition of many [[human culture]]s during the [[Neolithic]] period in [[Afro-Eurasia]] from a lifestyle of [[hunter-gatherer|hunting and gathering]] to one of [[agriculture]] and [[sedentism|settlement]], making an increasingly large population possible.<ref name=SCNDR>{{cite journal |title=When the World's Population Took Off: The Springboard of the Neolithic Demographic Transition |journal=Science |date=29 July 2011 |volume=333 |issue=6042 |pages=560–561 |doi=10.1126/science.1208880 |author=Jean-Pierre Bocquet-Appel |bibcode=2011Sci...333..560B |pmid=21798934 |s2cid=29655920}}</ref> These settled communities permitted humans to observe and experiment with plants, learning how they grew and developed.<ref name=":0">{{cite book |title=Worlds together, worlds apart |edition=concise |volume=1 |last1=Pollard |first1=Elizabeth |last2=Rosenberg |first2=Clifford |last3=Tigor |first3=Robert |publisher = W.W.

The Neolithic Revolution involved much more than the adoption of a limited set of food-producing techniques. During the next millennia, it transformed the small and mobile groups of hunter-gatherers that had hitherto dominated [[human history|human prehistory]] into [[sedentism|sedentary]] (non-[[nomad]]ic) [[society|societies]] based in built-up villages and towns. These societies radically modified their [[natural environment]] by means of specialized food-crop cultivation, with activities such as [[irrigation]] and [[deforestation]] which allowed the production of surplus food. Other developments that are found very widely during this era are the [[domestication of animals]], [[pottery]], polished stone tools, and rectangular houses. In many regions, the adoption of agriculture by prehistoric societies caused episodes of rapid population growth, a phenomenon known as the [[Neolithic demographic transition]].

These developments, sometimes called the '''Neolithic package''',<ref>{{Cite journal |last=Nowak |first=Marek |date=2022 |title=Do We Finally Know What the Neolithic Is? |journal=Open Archaeology |volume=8 |issue=1 |pages=332–342 |doi=10.1515/opar-2020-0204 |doi-access=free }}</ref> provided the basis for centralized administrations and political structures, hierarchical [[ideology|ideologies]],<ref>{{Cite web |url=https://unesdoc.unesco.org/ark:/48223/pf0000043086 |access-date=2023-10-18 |title=Violence and its causes |website=unesdoc.unesco.org}}</ref> depersonalized systems of knowledge (e.g. [[history of writing|writing]]), [[population density|densely populated]] settlements, specialization and [[division of labour]], more [[trade]], the development of non-portable [[art]] and [[architecture]], and greater [[property]] ownership.<ref name=":2">{{Cite journal |last=Childe |first=Vere Gordon |date=1950 |title=The Urban Revolution |journal=The Town Planning Review |publisher=[[Liverpool University Press]] |volume=21 |issue=1 |pages=3–17 |doi=10.3828/tpr.21.1.k853061t614q42qh |issn=0041-0020 |jstor=40102108 |s2cid=39517784 }}</ref> The [[Cradle of civilization|earliest known civilization]] developed in [[Sumer]] in southern [[Mesopotamia]] ({{circa| 6,500 [[Before Present|BP]]}}); its emergence also heralded the beginning of the [[Bronze Age]].<ref>{{Cite encyclopedia|url= https://www.worldhistory.org/Neolithic/|title= Neolithic Period|encyclopedia= [[World History Encyclopedia]]|first = Cristian |last=Violatti|date=2 April 2018}}</ref>

The relationship of the aforementioned Neolithic characteristics to the onset of agriculture, their sequence of emergence, and their empirical relation to each other at various Neolithic sites remains the subject of academic debate. It is usually understood to vary from place to place, rather than being the outcome of universal laws of [[Sociocultural evolution|social evolution]].<ref>[http://cas.bellarmine.edu/tietjen/images/neolithic_agriculture.htm "The Slow Birth of Agriculture"] {{webarchive |url=https://web.archive.org/web/20110101201656/http://cas.bellarmine.edu/tietjen/images/neolithic_agriculture.htm |date=1 January 2011 }}, [[Heather Pringle (writer)|Heather Pringle]]</ref><ref>{{cite web |url=http://www.mnsu.edu/emuseum/archaeology/sites/middle_east/zawichemishanidar.html |title=Wizard Chemi Shanidar |work=EMuseum |publisher=[[Minnesota State University]] |archive-url=https://web.archive.org/web/20080618214404/http://www.mnsu.edu/emuseum/archaeology/sites/middle_east/zawichemishanidar.html |archive-date=18 June 2008}}</ref>

==Background==
Prehistoric [[hunter-gatherer]]s had different [[subsistence]] requirements and lifestyles from agriculturalists. Hunter-gatherers were often highly mobile and migratory, living in temporary shelters and in small tribal groups, and having limited contact with outsiders. Their diet was well-balanced{{Citation needed|date=March 2025}} though heavily dependent on what the environment could provide each season. In contrast, because the [[surplus product|surplus]] and [[food security|plannable supply]] of food provided by agriculture made it possible to support larger population groups, agriculturalists lived in more permanent dwellings in more densely populated [[human settlement|settlement]]s than what could be supported by a hunter-gatherer lifestyle. The agricultural communities' seasonal need to plan and coordinate [[resource management|resource]] and [[manpower]] encouraged [[division of labor|division of labour]], which gradually led to [[skilled worker|specialization of labourers]] and [[complex societies]]. The subsequent development of [[trading network]]s to exchange surplus commodities and services brought agriculturalists into contact with outside groups, which promoted [[cultural exchange]]s that led to the rise of [[civilization]]s and [[technological evolution]]s.<ref name=cambridge>{{cite book |title=The Cambridge World History of Food |publisher=Cambridge University Press |page=46}}</ref>{{Full citation needed|date=August 2024 <!--Need at least the publication year and the volume.-->}}

However, higher population and food abundance did not necessarily correlate with improved health. Reliance on a very limited variety of [[staple crop]]s can adversely affect health even while making it possible to feed more people. As an example from the Americas, [[maize]] is deficient in certain essential [[amino acids]] ([[lysine]] and [[tryptophan]]) and is a poor source of [[iron]]. The [[phytic acid]] it contains may inhibit [[digestion|nutrient absorption]]. Other factors that likely affected the health of early agriculturalists and their domesticated [[livestock]] would have been increased numbers of [[parasites]] and disease-bearing pests associated with human waste and contaminated food and water supplies. [[Fertilizer]]s and [[irrigation]] may have increased crop yields but also would have promoted proliferation of [[insect]]s and [[bacteria]] in the local environment while grain storage attracted additional insects and [[rodents]].<ref name=cambridge/>

==Domestication==
{{Main|Domestication}}

=== Crops ===
Once agriculture started gaining momentum, around 9000 BP, human activity resulted in the [[selective breeding]] of cereal grasses (beginning with [[emmer]], [[einkorn]] and [[barley]]), and not simply of those that favoured greater caloric returns through larger seeds. Plants with traits such as small seeds or bitter taste were seen as undesirable. Plants that rapidly shed their seeds on maturity tended not to be gathered at harvest, therefore not stored and not seeded the following season; successive years of harvesting spontaneously selected for strains that retained their edible seeds longer.

[[Daniel Zohary]] identified several plant species as "pioneer crops" or [[Neolithic founder crops]]. He highlighted the importance of wheat, barley and rye, and suggested that domestication of [[flax]], [[pea]]s, [[chickpea]]s, [[Vicia ervilia|bitter vetch]] and [[lentil]]s came a little later. Based on analysis of the [[gene]]s of domesticated plants, he preferred theories of a single, or at most a very small number of domestication events for each [[taxon]] that spread in an arc from the [[Levantine corridor]] around the [[Fertile Crescent]] and later into Europe.<ref>{{Cite book|url=https://books.google.com/books?id=ZRi1AAAAIAAJ&q=The+Origins+and+Spread+of+Agriculture+and+Pastoralism+in+Eurasia|title=Origins & Spread Agric Past |editor-first=David R |editor-last= Harris |date=17 April 1996|publisher=Smithsonian|isbn=9781560986768 |via=Google Books}}</ref><ref>{{Cite journal|url=https://doi.org/10.1023/A:1008692912820|title=Monophyletic vs. polyphyletic origin of the crops on which agriculture was founded in the Near East|first=Daniel|last=Zohary|date=1 April 1999|journal=Genetic Resources and Crop Evolution|volume=46|issue=2|pages=133–142|via=Springer Link|doi=10.1023/A:1008692912820|s2cid=9529895 |url-access=subscription}}</ref> [[Gordon Hillman]] and Stuart Davies carried out experiments with varieties of wild wheat to show that the process of domestication would have occurred over a relatively short period of between 20 and 200 years.<ref>{{cite book | editor-last=Anderson | editor-first=PC | last1 = Hillman | first1 = G.

Most hunter-gatherers could not easily store food for long due to their migratory lifestyle, whereas those with a sedentary dwelling could store their surplus grain. Eventually [[granary|granaries]] were developed that allowed villages to store their seeds longer. So with more food, the population expanded and communities developed specialized workers and more advanced tools.

The process was not as linear as was once thought, but a more complicated effort, which was undertaken by different human populations in different regions in many different ways.

Therefore, it became necessary to bring animals permanently to their settlements, although in many cases there was a distinction between relatively sedentary farmers and nomadic herders.<ref>{{Cite news |title=The Development of Agriculture |url=https://genographic.nationalgeographic.com/development-of-agriculture/ |url-status=dead |archive-url=https://web.archive.org/web/20160414142437/https://genographic.nationalgeographic.com/development-of-agriculture/ |archive-date=14 April 2016 |access-date=21 July 2017 |work=Genographic Project |language=en-US}}</ref>{{original research inline|date=November 2016}} The animals' size, temperament, diet, mating patterns, and life span were factors in the desire and success in domesticating animals. Animals that provided milk, such as cows and goats, offered a source of protein that was renewable and therefore quite valuable. The animal's ability as a worker (for example ploughing or towing), as well as a food source, also had to be taken into account. Besides being a direct source of food, certain animals could provide leather, wool, hides, and fertilizer. Some of the earliest domesticated animals included [[Origin of the domestic dog|dogs]] ([[East Asia]], about 15,000 years ago),<ref>{{Cite news |last=McGourty |first=Christine |date=22 November 2002 |title=Origin of dogs traced |url=http://news.bbc.co.uk/2/hi/science/nature/2498669.stm |url-status=live |archive-url=https://web.archive.org/web/20191102051347/http://news.bbc.co.uk/2/hi/science/nature/2498669.stm |archive-date=2 November 2019 |access-date=29 November 2006 |publisher=BBC News}}</ref> sheep, goats, cows, and pigs.[[File:Menare.jpg|Dromedary caravan in Algeria|thumb|right]]

West Asia was the source for many animals that could be domesticated, such as sheep, goats and pigs. This area was also the first region to [[domesticate]] the [[dromedary]]. [[Henri Fleisch]] discovered and termed the [[Shepherd Neolithic]] [[flint]] industry from the [[Bekaa Valley]] in [[Lebanon]] and suggested that it could have been used by the earliest [[nomad]]ic [[shepherd]]s. He dated this industry to the [[Epipaleolithic]] or [[Pre-Pottery Neolithic]] as it is evidently not [[Paleolithic]], [[Mesolithic]] or even [[Pottery]] [[Neolithic]].<ref name="CopelandWescombe1966" /><ref>Fleisch, Henri., Notes de Préhistoire Libanaise : 1) Ard es Saoude. 2) La Bekaa Nord. 3) Un polissoir en plein air. BSPF, vol. 63.</ref>

The presence of these animals gave the region a large advantage in cultural and economic development. As the climate in the Middle East changed and became drier, many of the farmers were forced to leave, taking their domesticated animals with them. It was this massive emigration from the Middle East that later helped distribute these animals to the rest of [[Afroeurasia]]. This emigration was mainly on an east–west axis of similar climates, as crops usually have a narrow optimal climatic range outside of which they cannot grow for reasons of light or rain changes. For instance, wheat does not normally grow in tropical climates, just like tropical crops such as bananas do not grow in colder climates. Some authors, like [[Jared Diamond]], have postulated that this east–west axis is the main reason why plant and animal domestication spread so quickly from the [[Fertile Crescent]] to the rest of Eurasia and North Africa, while it did not reach through the north–south axis of [[Africa]] to reach the Mediterranean climates of [[South Africa]], where temperate crops were successfully imported by ships in the last 500 years.<ref name="diamond" /> Similarly, the African [[Zebu]] of central Africa and the domesticated bovines of the fertile-crescent – separated by the dry sahara desert – were not introduced into each other's region.

Agriculture appeared first in [[West Asia]] about 2,000 years later,{{clarify|reason=Later than what?|date=October 2024}} around 10,000–9,000 years ago. The region was the centre of domestication for three cereals (einkorn wheat, emmer wheat and barley), four legumes (lentil, pea, bitter vetch and chickpea), and flax. Domestication was a slow process that unfolded across multiple regions, and was preceded by centuries if not [[millennia]] of pre-domestication cultivation.<ref>{{Cite journal | last1= Brown | first1= T.

Finds of large quantities of seeds and a grinding stone at the [[Epipalaeolithic]] site of [[Ohalo II]], dating to around 19,400 BP, has shown some of the earliest evidence for advanced planning of plants for food consumption and suggests that humans at Ohalo II processed the grain before consumption.<ref>{{cite book |last= Mithen |first= Steven |title= After the ice : a global human history, 20.000–5.000 BC |year= 2006 |publisher= Harvard Univ.

In his 1997 book ''[[Guns, Germs, and Steel]]'', Jared Diamond argues that the vast continuous east–west stretch of temperate climatic zones of [[Eurasia]] and [[North Africa]] gave peoples living there a highly advantageous geographical location that afforded them a head start in the Neolithic Revolution. Both shared the temperate climate ideal for the first agricultural settings, and both were near a number of easily [[domestication|domesticable]] plant and animal species. In areas where continents aligned north–south such as the Americas and Africa, crops—and later domesticated animals—could not spread across tropical zones.<ref>{{Cite web|url=https://www.bbc.co.uk/history/ancient/british_prehistory/overview_british_prehistory_01.shtml|title=BBC – History – Ancient History in depth: Overview: From Neolithic to Bronze Age, 8000–800 BC|access-date=21 July 2017|archive-date=12 May 2021|archive-url=https://web.archive.org/web/20210512115703/http://www.bbc.co.uk/history/ancient/british_prehistory/overview_british_prehistory_01.shtml|url-status=live}}</ref>

There are two possible centres of domestication for rice. The first is in the lower [[Yangtze River]], believed to be the homelands of [[Austronesian peoples|pre-Austronesians]] and associated with the [[Kauhuqiao culture|Kauhuqiao]], [[Hemudu culture|Hemudu]], [[Majiabang culture|Majiabang]], and [[Songze culture|Songze]] [[Archaeological culture|cultures]]. It is characterized by typical pre-Austronesian features, including stilt houses, jade carving, and boat technologies. Their diet were also supplemented by [[acorn]]s, [[Eleocharis dulcis|water chestnuts]], [[foxnut]]s, and [[domesticated pig|pig]] domestication. The second is in the middle Yangtze River, believed to be the homelands of the early [[Hmong-Mien]]-speakers and associated with the [[Pengtoushan culture|Pengtoushan]] and [[Daxi culture|Daxi]] [[Archaeological culture|cultures]]. Both of these regions were heavily populated and had regular trade contacts with each other, as well as with early [[Austroasiatic]] speakers to the west, and early [[Kra-Dai]] speakers to the south, facilitating the spread of rice cultivation throughout southern China.<ref name="Zhang2012" /><ref name="He2017" /><ref name="Bellwood2011" />

[[File:Chronological dispersal of Austronesian people across the Pacific.svg|thumb|320px|Chronological dispersal of [[Austronesian peoples]] across the [[Indo-Pacific]] (Bellwood ''in'' Chambers, 2008)]]
The millet and rice-farming cultures also first came into contact with each other at around 9,000 to 7,000 BP, resulting in a corridor between the millet and rice cultivation centres where both rice and millet were cultivated.<ref name="He2017" /> At around 5,500 to 4,000 BP, there was increasing migration into [[Taiwan]] from the early Austronesian [[Dapenkeng culture]], bringing rice and millet cultivation technology with them. During this period, there is evidence of large settlements and intensive rice cultivation in Taiwan and the [[Penghu Islands]], which may have resulted in [[overexploitation]]. Bellwood (2011) proposes that this may have been the impetus of the [[Austronesian expansion]] which started with the migration of the Austronesian-speakers from Taiwan to the Philippines at around 5,000 BP.<ref name="Bellwood2011" />

Austronesians carried rice cultivation technology to [[Island Southeast Asia]] along with other domesticated species. The new tropical island environments also had new food plants that they exploited.

Unlike the Middle East, this evidence appears as a "false dawn" to agriculture, as the sites were later abandoned, and permanent farming then was delayed until 6,500 BP with the [[Tasian culture]] and [[Badarian]] culture and the arrival of crops and animals from the Near East.

[[Bananas]] and [[Plantain (cooking)|plantains]], which were first domesticated in [[Southeast Asia]], most likely [[Papua New Guinea]], were re-domesticated in Africa possibly as early as 5,000 years ago. Asian yams and [[taro]] were also cultivated in Africa.<ref name="diamond" />

The most famous crop domesticated in the Ethiopian highlands is [[coffee]]. In addition, [[khat]], [[ensete]], [[noog]], [[teff]] and [[finger millet]] were also domesticated in the Ethiopian highlands. Crops domesticated in the Sahel region include [[sorghum]] and [[pearl millet]]. The [[kola nut]] was first domesticated in West Africa. Other crops domesticated in West Africa include [[African rice]], [[Yam (vegetable)|yams]] and the [[oil palm]].<ref name="diamond" />

Agriculture spread to Central and Southern Africa in the [[Bantu expansion]] during the 1st millennium BCE to 1st millennium CE.

The term "Neolithic" is not customarily used in describing cultures in the Americas. However, a broad similarity exists between Eastern Hemisphere cultures of the Neolithic and cultures in the Americas. [[Maize]] (corn), [[beans]] and [[Squash (plant)|squash]] were among the earliest crops domesticated in [[Mesoamerica]]: squash as early as 6000 BCE, beans no later than 4000 BCE, and maize beginning about 7000 BCE.<ref>{{cite book |editor1=Johannessen, S. |editor2=Hastorf, C.

===New Guinea===
{{see also|Domesticated plants and animals of Austronesia}}
Evidence of drainage ditches at [[Kuk Swamp]] on the borders of the [[Western Highlands Province|Western]] and [[Southern Highlands Province|Southern Highlands]] of [[Papua New Guinea]] indicates cultivation of [[taro]] and a variety of other crops, dating back to 11,000 BP. Two potentially significant economic species, taro (''[[Colocasia esculenta]]'') and [[yam (vegetable)|yam]] (''[[Dioscorea]]'' sp.), have been identified dating at least to 10,200 calibrated years before present (cal BP). Further evidence of [[banana]]s and [[sugarcane]] dates to 6,950 to 6,440 BCE. This was at the altitudinal limits of these crops, and it has been suggested that cultivation in more favourable ranges in the lowlands may have been even earlier. [[Commonwealth Scientific and Industrial Research Organisation|CSIRO]] has found evidence that taro was introduced into the [[Solomon Islands (archipelago)|Solomon Islands]] for human use, from 28,000 years ago, making taro the earliest cultivated crop in the world.<ref>{{cite journal | last1=Fullagar | first1=Richard | last2=Field | first2=Judith | last3=Denham | first3=Tim | last4=Lentfer | first4=Carol | title=Early and mid Holocene tool-use and processing of taro (Colocasia esculenta), yam (Dioscorea sp.) and other plants at Kuk Swamp in the highlands of Papua New Guinea | journal=Journal of Archaeological Science | volume=33 | issue=5 | date=2006 | doi=10.1016/j.jas.2005.07.020 | pages=595–614| bibcode=2006JArSc..33..595F }}</ref><ref>{{cite journal | last1=Loy | first1=Thomas H. | last2=Spriggs | first2=Matthew | last3=Wickler | first3=Stephen | title=Direct evidence for human use of plants 28,000 years ago: starch residues on stone artefacts from the northern Solomon Islands | journal=Antiquity | volume=66 | issue=253 | date=1992 | issn=0003-598X | doi=10.1017/S0003598X00044811 | pages=898–912}}</ref>
It seems to have resulted in the spread of the [[Trans–New Guinea languages]] from New Guinea east into the Solomon Islands and west into [[Timor]] and adjacent areas of [[Indonesia]]. This seems to confirm the theories of [[Carl O. Sauer|Carl Sauer]] who, in "Agricultural Origins and Dispersals", suggested as early as 1952 that this region was a centre of early agriculture.

== Spread of agriculture ==

===Europe===
{{main|Neolithic Europe}}
[[File:Expansion of farming in western Eurasia, 9600–4000 BCE.png|thumb|upright=1.3|Spread of farming from Southwest Asia to Europe, between 9600 and 3800 BCE]]
Archaeologists trace the emergence of food-producing societies in the [[Levant]]ine region of southwest Asia at the close of the last glacial period around 12,000 BCE, and developed into a number of regionally distinctive cultures by the eighth millennium BCE. Remains of food-producing societies in the [[Aegean civilization|Aegean]] have been carbon-dated to {{circa|6500&nbsp;BCE}} at [[Knossos]], [[Franchthi Cave]], and a number of mainland sites in [[Thessaly]]. Neolithic groups appear soon afterwards in the [[Balkans]] and south-central Europe. The Neolithic cultures of [[southeastern Europe]] (the [[Balkans]] and the [[Aegean civilization|Aegean]]) show some continuity with groups in southwest Asia and [[Anatolia]] (e.g., [[Çatalhöyük]]).

Current evidence suggests that Neolithic material culture was introduced to Europe via western Anatolia. All Neolithic sites in Europe contain [[pottery|ceramics]], and contain the plants and animals domesticated in Southwest Asia: [[einkorn]], [[emmer]], [[barley]], [[lentil]]s, [[pig]]s, [[goat]]s, [[sheep]], and [[cattle]]. Genetic data suggest that no independent domestication of animals took place in Neolithic Europe, and that all domesticated animals were originally domesticated in Southwest Asia.{{sfn|Bellwood|2004|pp=68–69}} The only domesticate not from Southwest Asia was [[broomcorn millet]], domesticated in East Asia.{{sfn|Bellwood|2004|pp=74, 118}}The earliest evidence of [[cheese]]-making dates to 5500 BCE in [[Kujawy]], [[Poland]].<ref>{{cite journal |last=Subbaraman |first=Nidhi |date=12 December 2012 |title=Art of cheese-making is 7,500 years old |url=http://www.nature.com/news/art-of-cheese-making-is-7-500-years-old-1.12020 |url-status=live |journal=Nature News |doi=10.1038/nature.2012.12020 |s2cid=180646880 |archive-url=https://web.archive.org/web/20210508085311/https://www.nature.com/news/art-of-cheese-making-is-7-500-years-old-1.12020 |archive-date=8 May 2021 |access-date=17 January 2020|url-access=subscription }}</ref>

The diffusion across Europe, from the Aegean to Britain, took about 2,500 years (8500–6000 BP). The Baltic region was penetrated a bit later, around 5500 BP, and there was also a delay in settling the [[Pannonian plain]]. In general, colonization shows a "saltatory" pattern, as the Neolithic advanced from one patch of fertile alluvial soil to another, bypassing mountainous areas. Analysis of [[radiocarbon]] dates show clearly that Mesolithic and Neolithic populations lived side by side for as much as a millennium in many parts of Europe, especially in the [[Iberian peninsula]] and along the Atlantic coast.{{sfn|Bellwood|2004|pp=68–72}}

The earliest Neolithic site in South Asia is [[Mehrgarh]], dated to between 6500 and 5500 BCE, in the [[Kacchi Plain|Kachi plain]] of [[Balochistan, Pakistan|Balochistan]], Pakistan; the site has evidence of farming (wheat and barley) and herding (cattle, sheep and goats).<ref>{{cite book |last1=Coningham |first1=Robin |title=The Archaeology of South Asia: From the Indus to Asoka, c. 6500 BCE–200 CE |last2=Young |first2=Ruth |publisher=Cambridge University Press |year=2015 |isbn=978-1-316-41898-7 |page=111}}</ref>

Neolithic domesticated crops in Mehrgarh include more than 90% barley and a small amount of wheat. There is good evidence for the local domestication of barley and the zebu cattle at Mehrgarh, but the wheat varieties are suggested to be of Near-Eastern origin, as the modern distribution of wild varieties of wheat is limited to Northern Levant and Southern Turkey.<ref name="AS1-6" />

A detailed satellite map study of a few archaeological sites in the Baluchistan and Khybar Pakhtunkhwa regions also suggests similarities in early phases of farming with sites in Western Asia.<ref name="AS1-6" /> Pottery prepared by sequential slab construction, circular fire pits filled with burnt pebbles, and large granaries are common to both Mehrgarh and many Mesopotamian sites.<ref name="AS1-6" />

The postures of the skeletal remains in graves at Mehrgarh bear strong resemblance to those at Ali Kosh in the Zagros Mountains of southern Iran.<ref name="AS1-6" /> Despite their scarcity, the Carbon-14 and archaeological age determinations for early Neolithic sites in Southern Asia exhibit remarkable continuity across the vast region from the Near East to the Indian Subcontinent, consistent with a systematic eastward spread at a speed of about 0.65&nbsp;km/yr.<ref name="AS1-6" />

{{Missing information|section|more recent theories and includes some outdated/rejected theories|date=October 2024}}
The most prominent of several theories (not mutually exclusive) as to factors that caused populations to develop agriculture include:
* The Oasis Theory, originally proposed by [[Raphael Pumpelly]] in 1908, popularized by [[V. Gordon Childe]] in 1928 and summarised in Childe's book ''Man Makes Himself''.<ref name="ManChilde" /> This theory maintains that as the climate got drier due to the Atlantic depressions shifting northward, communities contracted to [[oases]] where they were forced into close association with animals, which were then domesticated together with planting of seeds. However, this theory now has little support amongst archaeologists because subsequent climate data suggests that the region was getting wetter rather than drier.<ref>{{cite book |last=Scarre |first=Christopher |title=The Human Past: World Prehistory and the Development of Human Societies |date=2005 |publisher=Thames & Hudson |isbn=0-500-28531-4 |publication-place=London |page=188 |chapter=The World Transformed: From Foragers and Farmers to States and Empires}}</ref>
* The [[Hilly Flanks]] hypothesis, proposed by [[Robert John Braidwood]] in 1948, suggests that agriculture began in the hilly flanks of the [[Taurus Mountains|Taurus]] and [[Zagros Mountains]], where the climate was not drier as Childe had believed, and fertile land supported a variety of plants and animals amenable to domestication.<ref>{{cite book |author=Charles E. Redman |title=Rise of Civilization: From Early Hunters to Urban Society in the Ancient Near East |publisher=Freeman |year=1978 |location=San Francisco}}</ref>

Douglas Price |location=Madison |pages=11–18 |chapter=Models of Domestication}}</ref> suggests that agriculture was driven by ostentatious displays of power, such as giving feasts, to exert dominance.

Various social and economic factors helped drive the need for food.

* [[Leonid Grinin]] argues that whatever plants were cultivated, the independent invention of agriculture always occurred in special natural environments (e.g., South-East Asia). It is supposed that the cultivation of cereals started somewhere in the Near East: in the hills of Israel or Egypt. So Grinin dates the beginning of the agricultural revolution within the interval 12,000 to 9,000 BP, though in some cases the first cultivated plants or domesticated animals' bones are even of a more ancient age of 14–15 thousand years ago.<ref>Grinin L.E.

* [[Andrew M. T. Moore|Andrew Moore]] suggested that the Neolithic Revolution originated over long periods of development in the [[Levant]], possibly beginning during the [[Epipaleolithic]]. In ''"A Reassessment of the Neolithic Revolution"'', [[Frank Hole]] further expanded the relationship between plant and [[animal domestication]]. He suggested the events could have occurred independently during different periods of time, in as yet unexplored locations. He noted that no transition site had been found documenting the shift from what he termed immediate and delayed return social systems.{{Explain|date=September 2024}} He noted that the full range of domesticated animals ([[goat]]s, [[sheep]], [[cattle]] and [[pigs]]) were not found until the sixth millennium BCE at [[Tell Ramad]]. Hole concluded that "close attention should be paid in future investigations to the western margins of the [[Euphrates]] basin, perhaps as far south as the [[Arabian Peninsula]], especially where [[wadi]]s carrying Pleistocene rainfall runoff flowed."<ref>{{Cite journal |last=Hole |first=Frank |date=29 August 1984 |title=A Reassessment of the Neolithic Revolution |url=https://www.persee.fr/doc/paleo_0153-9345_1984_num_10_2_939 |url-status=live |journal=Paléorient |volume=10 |issue=2 |pages=49–60 |doi=10.3406/paleo.1984.939 |archive-url=https://web.archive.org/web/20220617210526/https://www.persee.fr/doc/paleo_0153-9345_1984_num_10_2_939 |archive-date=17 June 2022 |access-date=29 August 2022 |via=Persée |doi-access=free}}</ref>

===Social change===
[[File:World population growth (lin-log scale).png|thumb|left|320px|World population (estimated) did not rise for a few millennia after the Neolithic revolution.]]

Despite the significant technological advance and advancements in knowledge, arts and trade, the Neolithic revolution did not lead immediately to a rapid growth of population. Its benefits appear to have been offset by various adverse effects, mostly diseases and warfare.<ref>[[James C. Scott]],''Against the Grain: a Deep History of the Earliest States'', NJ: Yale UP, (2017), "The world's population in 10 000 BC, according to a careful estimate was roughly 4 million. A full five thousand years later it has risen only to 5 million...One likely explanation for this apparent human progress in subsistance techniques together with a long period of demographic stagnation is that epidemologically this was perhaps the most lethal period in human history".</ref><ref>{{Cite web |date=2019-04-05 |title=What was the Neolithic Revolution? |url=https://www.nationalgeographic.com/culture/article/neolithic-agricultural-revolution |access-date=2023-06-18 |website=National Geographic |language=en |archive-date=9 October 2022 |archive-url=https://web.archive.org/web/20221009132816/https://www.nationalgeographic.com/culture/article/neolithic-agricultural-revolution |url-status=dead }}</ref>

The introduction of agriculture has not necessarily led to unequivocal progress. The nutritional standards of the growing Neolithic populations were inferior to that of hunter-gatherers. Several ethnological and archaeological studies conclude that the transition to cereal-based diets caused a reduction in life expectancy and stature, an increase in infant mortality and infectious diseases, the development of chronic, inflammatory or degenerative diseases (such as obesity, [[type 2 diabetes]] and cardiovascular diseases) and multiple nutritional deficiencies, including vitamin deficiencies, [[iron deficiency anemia]] and mineral disorders affecting bones (such as [[osteoporosis]] and [[rickets]]) and teeth.<ref name="SandsMorris2009">{{cite journal| vauthors=Sands DC, Morris CE, Dratz EA, Pilgeram A| title=Elevating optimal human nutrition to a central goal of plant breeding and production of plant-based foods. | journal=Plant Sci | year= 2009 | volume= 177 | issue= 5 | pages= 377–389 | pmid=20467463 | doi=10.1016/j.plantsci.2009.07.011 | pmc=2866137 | bibcode=2009PlnSc.177..377S |  type=Review }}</ref><ref name="OKeefeCordain2004">{{cite journal| vauthors=O'Keefe JH, Cordain L| title=Cardiovascular disease resulting from a diet and lifestyle at odds with our Paleolithic genome: how to become a 21st-century hunter-gatherer. | journal=Mayo Clin Proc | year= 2004 | volume= 79 | issue= 1 | pages= 101–108 | pmid=14708953 | doi=10.4065/79.1.101 | type=Review | doi-access=free }}</ref><ref name="Shermer, Michael 2001 p.250">{{cite book |author=Shermer, Michael |author-link=Michael Shermer |year=2001 |title=The Borderlands of Science |url=https://archive.org/details/borderlandsofsci00mic_hoo |url-access=registration |publisher=Oxford University Press |page=[https://archive.org/details/borderlandsofsci00mic_hoo/page/250 250]}}</ref> Average height for Europeans went down from {{convert|178|cm|ftin}} for men and {{convert|168|cm|ftin}} for women to {{convert|165|and|155|cm|ftin}} respectively, and it took until the twentieth century for average height for Europeans to return to the pre-Neolithic Revolution levels.<ref>{{cite journal | last1=Hermanussen | first1=Michael | last2=Poustka | first2=Fritz | title=Stature of early Europeans | journal=Hormones (Athens) | volume=2 | issue=3 | pages=175–178 | date=July–September 2003 | pmid=17003019 | doi=10.1159/000079404 | s2cid=85210429 | url=http://hormones.gr/preview.php?c_id=127 | access-date=12 June 2014 | archive-date=2 April 2012 | archive-url=https://web.archive.org/web/20120402221148/http://hormones.gr/preview.php?c_id=127 | url-status=live | url-access=subscription }}</ref>

The traditional view is that agricultural food production supported a denser population, which in turn supported larger sedentary communities, the accumulation of goods and tools, and specialization in diverse forms of new labor. Food surpluses made possible the development of a social elite who were not otherwise engaged in agriculture, industry or commerce, but dominated their communities by other means and monopolized decision-making. Nonetheless, larger societies made it more feasible for people to adopt diverse decision making and governance models.<ref name="Eagly99">{{cite journal |author1=Eagly, Alice H. |author2=Wood, Wendy |title=The Origins of Sex Differences in Human Behavior: Evolved Dispositions Versus Social Roles |journal=American Psychologist |volume=54 |issue=6 |date=June 1999 |pages=408–423 |url=http://www.sscnet.ucla.edu/anthro/faculty/fiske/facets/eagly&wood.htm |archive-url=https://web.archive.org/web/20000817071347/http://www.sscnet.ucla.edu/anthro/faculty/fiske/facets/eagly&wood.htm |url-status=dead |archive-date=17 August 2000 |doi=10.1037/0003-066x.54.6.408|url-access=subscription }}</ref> Jared Diamond (in ''[[The World Until Yesterday]]'') identifies the availability of milk and cereal grains as permitting mothers to raise both an older (e.g. 3 or 4 year old) and a younger child concurrently.

===Subsequent revolutions===
[[File:Egyptian Domesticated Animals.jpg|thumb|Domesticated cow being milked in [[Ancient Egypt]]]]

[[Andrew Sherratt]] has argued that following upon the Neolithic Revolution was a second phase of discovery that he refers to as the [[secondary products revolution]]. Animals, it appears, were first domesticated purely as a source of meat.<ref name="Sherratt 1981">{{cite book | last=Sherratt | first=A | editor-last1=Hodder | editor-first1=Ian | editor-last2=Isaac | editor-first2=Glynn Llywelyn | editor-last3=Hammond | editor-first3=Norman | title=Pattern of the Past: Studies in honour of David Clarke | chapter = Plough and pastoralism: aspects of the secondary products revolution | publisher=Cambridge University Press | publication-place=Cambridge | year=1981 | isbn=978-0-521-22763-6 | pages=261–305}}</ref> The Secondary Products Revolution occurred when it was recognised that animals also provided a number of other useful products. These included:
* [[History of hide materials|hides and skins (from undomesticated animals)]]
* [[manure]] for soil conditioning (from all domesticated animals)
* [[wool]] (from sheep, llamas, alpacas, and [[Angora goat]]s)
* [[milk]] (from goats, cattle, yaks, sheep, horses, and camels)
* [[Working animal|traction]] (from oxen, [[onagers]], donkeys, horses, camels, and dogs)
* guarding and herding assistance (dogs)

Sherratt argued that this phase in agricultural development enabled humans to make use of the energy possibilities of their animals in new ways, and permitted permanent intensive subsistence farming and crop production, and the opening up of heavier soils for farming. It also made possible [[nomadic pastoralism]] in semi arid areas, along the margins of deserts, and eventually led to the domestication of both the [[dromedary]] and [[Bactrian camel]].<ref name="Sherratt 1981"/> Overgrazing of these areas, particularly by herds of goats, greatly extended the areal extent of deserts.

===Diet and health===

Compared to foragers, Neolithic farmers' diets were higher in [[carbohydrate]]s but lower in [[Dietary fiber|fibre]], [[micronutrient]]s, and [[protein]]. This led to an increase in the frequency of [[Tooth decay|carious]] teeth<ref name=Larsen2006>{{Cite journal|last=Larsen|first=Clark Spencer|date=1 June 2006|title=The agricultural revolution as environmental catastrophe: Implications for health and lifestyle in the Holocene|url=http://www.sciencedirect.com/science/article/pii/S1040618206000334|journal=Quaternary International|series=Impact of rapid environmental changes on humans and ecosystems|language=en|volume=150|issue=1|pages=12–20|doi=10.1016/j.quaint.2006.01.004|bibcode=2006QuInt.150...12L|issn=1040-6182|access-date=10 July 2020|archive-date=5 November 2019|archive-url=https://web.archive.org/web/20191105150829/https://www.sciencedirect.com/science/article/pii/S1040618206000334|url-status=live|url-access=subscription}}</ref> and slower growth in childhood {{Clarify | text = and increased [[body fat]]| date = September 2024 | reason = Unclear if this is just for children or for the entire population.}}, and studies have consistently found that populations around the world became shorter after the transition to agriculture.

Throughout the development of sedentary societies, disease spread more rapidly than it had during the time in which hunter-gatherer societies existed. Inadequate sanitary practices and the domestication of animals may explain the rise in deaths and sickness following the Neolithic Revolution, as diseases jumped from the animal to the human population. Some examples of [[infectious diseases]] spread from animals to humans are [[influenza]], [[smallpox]], and [[measles]].<ref>{{Cite journal | last1=Furuse | first1=Y. | last2=Suzuki | first2=A. | last3=Oshitani | first3=H. | title=Origin of measles virus: Divergence from rinderpest virus between the 11th and 12th centuries | doi=10.1186/1743-422X-7-52 | journal=Virology Journal | volume=7 | page=52 | year=2010 | pmc=2838858 | pmid=20202190 | doi-access=free }}</ref> Ancient microbial genomics has shown that progenitors to human-adapted strains of ''[[Salmonella enterica]]'' infected up to 5,500 year old agro-pastoralists throughout Western Eurasia, providing molecular evidence for the hypothesis that the Neolithization process facilitated the emergence of Salmonella entericia.<ref>{{cite journal |last1=Key |first1=Felix M. |last2=Posth |first2=Cosimo |last3=Esquivel-Gomez |first3=Luis R. |last4=Hübler |first4=Ron |last5=Spyrou |first5=Maria A. |last6=Neumann |first6=Gunnar U. |last7=Furtwängler |first7=Anja |last8=Sabin |first8=Susanna |last9=Burri |first9=Marta |last10=Wissgott |first10=Antje |last11=Lankapalli |first11=Aditya Kumar |last12=Vågene |first12=Åshild J. |last13=Meyer |first13=Matthias |last14=Nagel |first14=Sarah |last15=Tukhbatova |first15=Rezeda |last16=Khokhlov |first16=Aleksandr |last17=Chizhevsky |first17=Andrey |last18=Hansen |first18=Svend |last19=Belinsky |first19=Andrey B. |last20=Kalmykov |first20=Alexey |last21=Kantorovich |first21=Anatoly R. |last22=Maslov |first22=Vladimir E. |last23=Stockhammer |first23=Philipp W. |last24=Vai |first24=Stefania |last25=Zavattaro |first25=Monica |last26=Riga |first26=Alessandro |last27=Caramelli |first27=David |last28=Skeates |first28=Robin |last29=Beckett |first29=Jessica |last30=Gradoli |first30=Maria Giuseppina |last31=Steuri |first31=Noah |last32=Hafner |first32=Albert |last33=Ramstein |first33=Marianne |last34=Siebke |first34=Inga |last35=Lösch |first35=Sandra |last36=Erdal |first36=Yilmaz Selim |last37=Alikhan |first37=Nabil-Fareed |last38=Zhou |first38=Zhemin |last39=Achtman |first39=Mark |last40=Bos |first40=Kirsten |last41=Reinhold |first41=Sabine |last42=Haak |first42=Wolfgang |last43=Kühnert |first43=Denise |last44=Herbig |first44=Alexander |last45=Krause |first45=Johannes |title=Emergence of human-adapted Salmonella enterica is linked to the Neolithization process |journal=Nature Ecology & Evolution |date=March 2020 |volume=4 |issue=3 |pages=324–333 |doi=10.1038/s41559-020-1106-9 |pmid=32094538 |pmc=7186082 |bibcode=2020NatEE...4..324K |language=en |issn=2397-334X}}</ref>

In concordance with a process of [[natural selection]], the humans who first domesticated the big [[mammals]] quickly built up immunities to the diseases as within each generation the individuals with better immunities had better chances of survival. In their approximately 10,000 years of shared proximity with animals, such as cows, Eurasians and Africans became more resistant to those diseases compared with the indigenous populations encountered outside [[Eurasia]] and [[Africa]].<ref name="diamond"/> For instance, the population of most [[Caribbean]] and several [[Pacific Islands]] have been completely wiped out by diseases. 90% or more of many populations of the Americas were [[Population history of indigenous peoples of the Americas|wiped out by European and African diseases]] before recorded contact with European explorers or colonists. Some cultures like the [[Inca Empire]] did have a large domestic mammal, the [[llama]], but llama milk was not drunk, nor did llamas live in a closed space with humans, so the risk of contagion was limited. According to bioarchaeological research, the effects of agriculture on dental health in Southeast Asian rice farming societies from 4000 to 1500 BP was not detrimental to the same extent as in other world regions.<ref>{{cite journal |last1=Halcrow |first1=S.

[[Jonathan C. K. Wells]] and [[Jay T. Stock]] have argued that the dietary changes and increased pathogen exposure associated with agriculture profoundly altered human biology and [[Life history theory|life history]], creating conditions where [[natural selection]] favoured the allocation of resources towards [[reproduction]] over [[somatic effort]].<ref name=":1" />
