The Neolithic Revolution, Neolithic Demographic Transition, Agricultural Revolution, or First Agricultural Revolution was the wide-scale transition of many human cultures during the Neolithic period from a lifestyle of hunting and gathering to one of agriculture and settlement, making an increasingly larger population possible. These settled communities permitted humans to observe and experiment with plants to learn how they grew and developed. This new knowledge led to the domestication of plants.
Archaeological data indicates that the domestication of various types of plants and animals happened in separate locations worldwide, starting in the geological epoch of the Holocene around 12,500 years ago. It was the world's first historically verifiable revolution in agriculture. The Neolithic Revolution greatly narrowed the diversity of foods available, resulting in a downturn in the quality of human nutrition.
The Neolithic Revolution involved far more than the adoption of a limited set of food-producing techniques. During the next millennia it would transform the small and mobile groups of hunter-gatherers that had hitherto dominated human pre-history into sedentary (non-nomadic) 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 found very widely are the domestication of animals, pottery, polished stone tools, and rectangular houses.
These developments, sometimes called the Neolithic package, provided the basis for centralized administrations and political structures, hierarchical ideologies, depersonalized systems of knowledge (e.g. writing), densely populated settlements, specialization and division of labour, more trade, the development of non-portable art and architecture, and property ownership. The earliest known civilization developed in Sumer in southern Mesopotamia (c. 6,500 BP); its emergence also heralded the beginning of the Bronze Age.
The relationship of the above-mentioned Neolithic characteristics to the onset of agriculture, their sequence of emergence, and empirical relation to each other at various Neolithic sites remains the subject of academic debate, and varies from place to place, rather than being the outcome of universal laws of social evolution. The Levant saw the earliest developments of the Neolithic Revolution from around 10,000 BCE, followed by sites in the wider Fertile Crescent.
The term Neolithic Revolution was coined in 1923 by V. Gordon Childe to describe the first in a series of agricultural revolutions in Middle Eastern history. The period is described as a "revolution" to denote its importance, and the great significance and degree of change affecting the communities in which new agricultural practices were gradually adopted and refined.
The beginning of this process in different regions has been dated from 10,000 to 8,000 BCE in the Fertile Crescent and perhaps 8000 BCE in the Kuk Early Agricultural Site of Melanesia. This transition everywhere seems associated with a change from a largely nomadic hunter-gatherer way of life to a more settled, agrarian-based one, with the inception of the domestication of various plant and animal species—depending on the species locally available, and probably also influenced by local culture. Recent archaeological research suggests that in some regions such as the Southeast Asian peninsula, the transition from hunter-gatherer to agriculturalist was not linear, but region-specific.
There are several competing (but not mutually exclusive) theories as to the factors that drove populations to take up agriculture. The most prominent of these are:
Use-wear analysis of five glossed flint blades found at Ohalo II, a 23,000-years-old fisher-hunter-gatherers’ camp on the shore of the Sea of Galilee, Northern Israel, provides the earliest evidence for the use of composite cereal harvesting tools. The Ohalo site is at the junction of the Upper Paleolithic and the Early Epipaleolithic, and has been attributed to both periods.
The wear traces indicate that tools were used for harvesting near-ripe semi-green wild cereals, shortly before grains are ripe and disperse naturally. The studied tools were not used intensively, and they reflect two harvesting modes: flint knives held by hand and inserts hafted in a handle. The finds shed new light on cereal harvesting techniques some 8,000 years before the Natufian and 12,000 years before the establishment of sedentary farming communities in the Near East. Furthermore, the new finds accord well with evidence for the earliest ever cereal cultivation at the site and the use of stone-made grinding implements.
Once agriculture started gaining momentum, around 9000 BCE, human activity resulted in the selective breeding of cereal grasses (beginning with emmer, einkorn and barley), and not simply of those that would favour greater caloric returns through larger seeds. Plants with traits such as small seeds or bitter taste would have been 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, peas, chickpeas, bitter vetch and lentils came a little later. Based on analysis of the genes 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. 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. Some of the pioneering attempts failed at first and crops were abandoned, sometimes to be taken up again and successfully domesticated thousands of years later: rye, tried and abandoned in Neolithic Anatolia, made its way to Europe as weed seeds and was successfully domesticated in Europe, thousands of years after the earliest agriculture. Wild lentils presented a different problem: most of the wild seeds do not germinate in the first year; the first evidence of lentil domestication, breaking dormancy in their first year, appears in the early Neolithic at Jerf el Ahmar (in modern Syria), and lentils quickly spread south to the Netiv HaGdud site in the Jordan Valley. The process of domestication allowed the founder crops to adapt and eventually become larger, more easily harvested, more dependable in storage and more useful to the human population.
Selectively propagated figs, wild barley and wild oats were cultivated at the early Neolithic site of Gilgal I, where in 2006 archaeologists found caches of seeds of each in quantities too large to be accounted for even by intensive gathering, at strata datable to c. 11,000 years ago. Some of the plants tried and then abandoned during the Neolithic period in the Ancient Near East, at sites like Gilgal, were later successfully domesticated in other parts of the world.
Once early farmers perfected their agricultural techniques like irrigation (traced as far back as the 6th millennium BCE in Khuzistan), their crops would yield surpluses that needed storage. 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 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.
One of the world’s most important crops, barley, was domesticated in the Near East around 11,000 years ago (circa 9,000 BCE). Barley is a highly resilient crop, able to grown in varied and marginal environments, such as in regions of high altitude and latitude. Archaeobotanical evidence shows that barley had spread throughout Eurasia by 2,000 BCE. To further elucidate the routes by which barley cultivation was spread through Eurasia, genetic analysis was used to determine genetic diversity and population structure in extant barley taxa. Genetic analysis shows that cultivated barley spread through Eurasia via several different routes, which were most likely separated in both time and space.
The site of Gesher in modern Israel is the earliest known Neolithic site according to calibrated Carbon 14 datation, at 10,459 BCE ± 348 years. This suggests that Gesher may have been the center of a Neolithic revolution, from which the new technology then spread.
Agriculture appeared first in Southwest Asia about 2,000 years later, 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.
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. Tell Aswad is the oldest site of agriculture, with domesticated emmer wheat dated to 10,800 BP. Soon after came hulled, two-row barley - found domesticated earliest at Jericho in the Jordan valley and at Iraq ed-Dubb in Jordan. Other sites in the Levantine corridor that show early evidence of agriculture include Wadi Faynan 16 and Netiv Hagdud. Jacques Cauvin noted that the settlers of Aswad did not domesticate on site, but "arrived, perhaps from the neighbouring Anti-Lebanon, already equipped with the seed for planting". In the Eastern Fertile Crescent, evidence of cultivation of wild plants has been found in Choga Gholan in Iran dated to 12,000 BP, suggesting there were multiple regions in the Fertile Crescent where domestication evolved roughly contemporaneously. The Heavy Neolithic Qaraoun culture has been identified at around fifty sites in Lebanon around the source springs of the River Jordan, but never reliably dated.
Archeologists trace the emergence of food-producing societies in the Levantine 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 have been carbon-dated to around 6500 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) 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 ceramics, and contain the plants and animals domesticated in Southwest Asia: einkorn, emmer, barley, lentils, pigs, goats, 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. The only domesticate not from Southwest Asia was broomcorn millet, domesticated in East Asia.The earliest evidence of cheese-making dates to 5500 BCE in Kujawy, Poland.
The diffusion across Europe, from the Aegean to Britain, took about 2,500 years (6500 BCE - 4000 BCE). The Baltic region was penetrated a bit later, around 3500 BCE, 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.
The spread of the Neolithic from the Near East Neolithic to Europe was first studied quantitatively in the 1970s, when a sufficient number of Carbon 14 age determinations for early Neolithic sites had become available. Ammerman and Cavalli-Sforza discovered a linear relationship between the age of an Early Neolithic site and its distance from the conventional source in the Near East (Jericho), thus demonstrating that, on average, the Neolithic spread at a constant speed of about 1 km/yr. More recent studies confirm these results and yield the speed of 0.6–1.3 km/yr at 95% confidence level.
Since the original human expansions out of Africa 200,000 years ago, different prehistoric and historic migration events have taken place in Europe. Considering that the movement of the people implies a consequent movement of their genes, it is possible to estimate the impact of these migrations through the genetic analysis of human populations. Agricultural and husbandry practices originated 10,000 years ago in a region of the Near East known as the Fertile Crescent. According to the archaeological record this phenomenon, known as “Neolithic”, rapidly expanded from these territories into Europe. However, whether this diffusion was accompanied or not by human migrations is greatly debated. Mitochondrial DNA –a type of maternally inherited DNA located in the cell cytoplasm- was recovered from the remains of Pre-Pottery Neolithic B (PPNB) farmers in the Near East and then compared to available data from other Neolithic populations in Europe and also to modern populations from South Eastern Europe and the Near East. The obtained results show that substantial human migrations were involved in the Neolithic spread and suggest that the first Neolithic farmers entered Europe following a maritime route through Cyprus and the Aegean Islands.
The earliest Neolithic sites in South Asia are Bhirrana in Haryana dated to 7570-6200 BC, and Mehrgarh, dated to between 6500 and 5500 BC, in the Kachi plain of Baluchistan, Pakistan; the site has evidence of farming (wheat and barley) and herding (cattle, sheep and goats).
There is strong evidence for causal connections between the Near-Eastern Neolithic and that further east, up to the Indus Valley. There are several lines of evidence that support the idea of connection between the Neolithic in the Near East and in the Indian subcontinent. The prehistoric site of Mehrgarh in Baluchistan (modern Pakistan) is the earliest Neolithic site in the north-west Indian subcontinent, dated as early as 8500 BCE. Neolithic domesticated crops in Mehrgarh include more than 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. 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. 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. 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. Despite their scarcity, the 14C 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 km/yr.
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.
The first agricultural center in northern China is believed to be the homelands of the early Sino-Tibetan-speakers, associated with the Houli, Peiligang, Cishan, and Xinglongwa cultures, clustered around the Yellow River basin. It was the domestication center for foxtail millet (Setaria italica) and broomcorn millet (Panicum miliaceum) with evidence of domestication of these species approximately 8,000 years ago. These species were subsequently widely cultivated in the Yellow River basin (7,500 years ago). Soybean was also domesticated in northern China 4,500 years ago. Orange and peach also originated in China. They were cultivated around 2500 BC.
The second agricultural center in southern China are associated with the ancestors of modern Southeast Asians and clustered around the Yangtze River basin. Rice was domesticated in this region, together with the development of paddy field cultivation, between 13,500 to 8,200 years ago.
There are two possible centers of domestication for rice. The first, and most likely, is in the lower Yangtze River, believed to be the homelands of early Austronesian speakers and associated with the Kauhuqiao, Hemudu, Majiabang, and Songze cultures. It is characterized by typical Austronesian innovations, including stilt houses, jade carving, and boat technologies. Their diet were also supplemented by acorns, water chestnuts, foxnuts, and 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 and Daxi 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.
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 centers where both rice and millet were cultivated. 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.
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. They carried useful plants an animals during each colonization voyage, resulting in the rapid introduction of domesticated and semi-domesticated species throughout Oceania. They also came into contact with the early agricultural centers of Papuan-speaking populations of New Guinea as well as the Dravidian-speaking regions of South India and Sri Lanka by around 3,500 BP. They acquired further cultivated food plants like bananas and peppers from them, and in turn introduced Austronesian technologies like wetland cultivation and outrigger canoes. During the 1st millennium AD, they also colonized Madagascar and the Comoros, bringing Southeast Asian food plants, including rice, to East Africa.
On the African continent, three areas have been identified as independently developing agriculture: the Ethiopian highlands, the Sahel and West Africa. By contrast, Agriculture in the Nile River Valley is thought to have developed from the original Neolithic Revolution in the Fertile Crescent. Many grinding stones are found with the early Egyptian Sebilian and Mechian cultures and evidence has been found of a neolithic domesticated crop-based economy dating around 7,000 BP. 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 and Badarian cultures and the arrival of crops and animals from the Near East.
Bananas and 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.
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, yams and the oil palm.
Agriculture spread to Central and Southern Africa in the Bantu expansion during the 1st millennium BC to 1st millennium AD.
Maize (corn), beans and squash were among the earliest crops domesticated in Mesoamerica, with maize beginning about 4000 BC, squash as early as 6000 BC, and beans by no later than 4000 BC. Potatoes and manioc were domesticated in South America. In what is now the eastern United States, Native Americans domesticated sunflower, sumpweed and goosefoot around 2500 BC. Sedentary village life based on farming did not develop until the second millennium BC, referred to as the formative period.
Evidence of drainage ditches at Kuk Swamp on the borders of the Western and Southern Highlands of Papua New Guinea shows evidence of the 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 (Dioscorea sp.), have been identified dating at least to 10,200 calibrated years before present (cal BP). Further evidence of bananas and sugarcane dates to 6,950 to 6,440 BP. 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. CSIRO has found evidence that taro was introduced into the Solomon Islands for human use, from 28,000 years ago, making taro cultivation the earliest crop in the world. 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 Sauer who, in "Agricultural Origins and Dispersals", suggested as early as 1952 that this region was a centre of early agriculture.
When hunter-gathering began to be replaced by sedentary food production it became more profitable to keep animals close at hand. 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. 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 dogs (East Asia, about 15,000 years ago), sheep, goats, cows, and pigs.
The Middle East served as 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 nomadic shepherds. He dated this industry to the Epipaleolithic or Pre-Pottery Neolithic as it is evidently not Paleolithic, Mesolithic or even Pottery Neolithic. 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 would later help 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. 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.
Despite the significant technological advance, 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.
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. Average height went down from 5'10" (178 cm) for men and 5'6" (168 cm) for women to 5'5" (165 cm) and 5'1" (155 cm), respectively, and it took until the twentieth century for average human height to come back to the pre-Neolithic Revolution levels.
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. The development of larger societies led to the development of different means of decision making and to governmental organization. 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. 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. The result is that a population can increase more rapidly. Diamond, in agreement with feminist scholars such as V. Spike Peterson, points out that agriculture brought about deep social divisions and encouraged gender inequality.
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. The Secondary Products Revolution occurred when it was recognised that animals also provided a number of other useful products. These included:
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. Overgrazing of these areas, particularly by herds of goats, greatly extended the areal extent of deserts.
Living in one spot would have more easily permitted the accrual of personal possessions and an attachment to certain areas of land. From such a position, it is argued, prehistoric people were able to stockpile food to survive lean times and trade unwanted surpluses with others. Once trade and a secure food supply were established, populations could grow, and society would have diversified into food producers and artisans, who could afford to develop their trade by virtue of the free time they enjoyed because of a surplus of food. The artisans, in turn, were able to develop technology such as metal weapons. Such relative complexity would have required some form of social organisation to work efficiently, so it is likely that populations that had such organisation, perhaps such as that provided by religion, were better prepared and more successful. In addition, the denser populations could form and support legions of professional soldiers. Also, during this time property ownership became increasingly important to all people. Ultimately, Childe argued that this growing social complexity, all rooted in the original decision to settle, led to a second Urban Revolution in which the first cities were built.
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. 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. 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 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 physical and dental health in Southeast Asian rice farming societies from 4000 to 1500 B.P. was not detrimental to the same extent as in other world regions.
In his book Guns, Germs, and Steel, Jared Diamond argues that Europeans and East Asians benefited from an advantageous geographical location that afforded them a head start in the Neolithic Revolution. Both shared the temperate climate ideal for the first agricultural settings, both were near a number of easily domesticable plant and animal species, and both were safer from attacks of other people than civilizations in the middle part of the Eurasian continent. Being among the first to adopt agriculture and sedentary lifestyles, and neighboring other early agricultural societies with whom they could compete and trade, both Europeans and East Asians were also among the first to benefit from technologies such as firearms and steel swords.
The dispersal of Neolithic culture from the Middle East has recently been associated with the distribution of human genetic markers. In Europe, the spread of the Neolithic culture has been associated with distribution of the E1b1b lineages and Haplogroup J that are thought to have arrived in Europe from North Africa and the Near East respectively. In Africa, the spread of farming, and notably the Bantu expansion, is associated with the dispersal of Y-chromosome haplogroup E1b1a from West Africa.
[...] the Neolithic transition involved increasing sedentism and social complexity, which was usually followed by the gradual adoption of plant and animal domestication. In some cases, however, plant domestication preceded sedentism, particularly in the New World.
Our earliest evidence for this new technology comes [...] from the lowland steppe of Khuzistan. [...] Once irrigation appeared, the steppe greatly increased its carrying capacity and became, in fact, the dominant growth centre of the Zagros region between 5500 and 4000 B.C.
Archeological investigations on the Deh Luran Plain of Iran have provided a model for the internal dynamics of the culture sequence of prehistoric Khuzistan [...]. Somewhere between 5500 and 5000 B.C. in the Sabz phase of the Deh Luran Plain, irrigation water was apparently diverted from stream channels in a fashion similar to that employed in early Mesopotamia.
Agricultural revolution may refer to:
First Agricultural Revolution (circa 10,000 BC), the prehistoric transition from hunting and gathering to settled agriculture (also known as the Neolithic Revolution)
Arab Agricultural Revolution (8th–13th century), the spread of new crops and advanced techniques in the Muslim world
British Agricultural Revolution (17th–19th century), an unprecedented increase in agricultural productivity in Great Britain (also known as the Second Agricultural Revolution)
Scottish Agricultural Revolution (17th–19th century), the transformation into a modern and productive system
Third Agricultural Revolution (1930s–1960s), an increase in agricultural production, especially in the developing world (also known as the Green Revolution)Akkar District
Akkar District (Arabic: قضاء عكار) is the only district in Akkar Governorate, Lebanon. It is coextensive with the governorate and covers an area of 788 km2 (304 sq mi). The UNHCR estimated the population of the district to be 389,899 in 2015, including 106,935 registered refugees of the Syrian Civil War and 19,404 Palestinian refugees. The capital is at Halba.
The district is characterized by the presence of a relatively large coastal plain, with high mountains to the east. The largest cities in Akkar are Halba, Bire Akkar and Al-Qoubaiyat.
Akkar has many important Roman and Arabic archaeological sites. One of the most famous archaeological sites and the birthplace of the Roman emperor Severus Alexander (d.235) is the Tell of Arqa near the town of Miniara. Several prehistoric sites were found in the Akkar plain foothills that were suggested to have been used by the Heavy Neolithic Qaraoun culture at the dawn of the Neolithic Revolution.Akkar can be divided into 7 parts: Qaitea (القيطع), Jouma (الجومة), Dreib (الدريب), Jabal Akroum (جبل أكروم), Wadi Khaled (وادي خالد), Cheft (الشفت) and As-sahel (السهل).There were three kings from Akkar: Elie Georges Kobrosi, Fadi Jawdat Tannous, and Rami Samir Yaacoub.Alpine race
The Alpine race is a historical race concept defined by some late 19th-century and early 20th-century anthropologists as one of the sub-races of the Caucasian race. The origin of the Alpine race was variously identified. Ripley argued that it migrated from Central Asia during the Neolithic revolution, splitting the Nordic and Mediterranean populations. It was also identified as descending from the Celts residing in Central Europe in Neolithic times. The Alpine race is mainly distinguished by its cranial measurements, such as high cephalic index.Early anthropocene
The Early Anthropocene Hypothesis (sometimes called Early Anthropogenic) was proposed by William Ruddiman. It posits that the Anthropocene era, as some scientists call the most recent period in Earth's history when the activities of the human race first began to have a significant global impact on Earth's climate and ecosystems, did not begin in the eighteenth century with advent of coal-burning factories and power plants of the industrial era, as was commonly assumed, but dates back to 8,000 years ago, triggered by intense farming activities after agriculture became widespread. It was at that time that atmospheric greenhouse gas concentrations stopped following the periodic pattern of rises and falls that had accurately characterized their past long-term behavior, a pattern that is explained by natural variations in Earth's orbit known as Milankovitch cycles.Epipalaeolithic Near East
The Epipalaeolithic Near East designates the Epipalaeolithic ("Final Old Stone Age", also known as Mesolithic) in the prehistory of the Near East. It is the period after the Upper Palaeolithic and before the Neolithic, between approximately 20,000 and 10,000 years Before Present (BP). The people of the Epipalaeolithic were nomadic hunter-gatherers that generally lived in small, seasonal camps rather than permanent villages. They made sophisticated stone tools using microliths—small, finely-produced blades that were hafted in wooden implements—which are the primary means by which archaeologists recognise and classify Epipalaeolithic sites.The start of the Epipalaeolithic is defined by the appearance of microliths. Although this is an arbitrary boundary, the Epipalaeolithic does differ significantly from the preceding Upper Palaeolithic. Epipalaeolithic sites are more numerous, better preserved and can be accurately radiocarbon dated. The period also coincides with the gradual retreat of glacial climatic conditions between the Last Glacial Maximum and the start of the Holocene and is characterised by population growth and economic intensification. The Epipalaeolithic ended with the "Neolithic Revolution" and the onset of domestication, food production, and sedentism – although archaeologists now recognise that these trends began in the Epipalaeolithic.The period may be subdivided into Early, Middle and Late Epipaleolithic: The Early Epipaleolithic corresponds to the Kebaran culture, c. 20,000 to 14,500 years ago, the Middle Epipaleolithic is the Geometric Kebaran or late phase of the Kebaran, and the Late Epipaleolithic to the Natufian, 14,500–11,500 BP. The Natufian overlaps with the incipient Neolithic Revolution, the Pre-Pottery Neolithic A.Holocene calendar
The Holocene calendar, also known as the Holocene Era or Human Era (HE), is a year numbering system that adds exactly 10,000 years to the currently dominant (AD/BC or CE/BCE) numbering scheme, placing its first year near the beginning of the Holocene geological epoch and the Neolithic Revolution, when humans transitioned from a hunter-gatherer lifestyle to agriculture and fixed settlements. The year 2019 in the Holocene calendar is 12019 HE. The HE scheme was first proposed by Cesare Emiliani in 1993 (11993 HE).Levantine corridor
The Levantine corridor is the relatively narrow strip between the Mediterranean Sea to the northwest and deserts to the southeast which connects Africa to Eurasia. This corridor is a land route of migrations of animals between Eurasia and Africa. In particular, it is believed that early hominins spread from Africa to Eurasia via the Levantine corridor and Horn of Africa. The corridor is named after the Levant.
The Levantine Corridor is the western part of the Fertile Crescent, the eastern part being Mesopotamia.
Botanists recognize this area as a dispersal route of plant species.The distribution of Y-chromosome and mtDNA haplogroups suggests that during the Paleolithic and Mesolithic periods, the Levantine corridor was more important for bi-directional human migrations between Africa and Eurasia than was the Horn of Africa.The first sedentary villages were established around fresh water springs and lakes in the Levantine corridor by the Natufian culture. The term is used frequently by archaeologists as an area that includes Cyprus, where important developments occurred during the Neolithic revolution.Mesolithic
In Old World archaeology, Mesolithic (Greek: μέσος, mesos "middle"; λίθος, lithos "stone") is the period between the Upper Paleolithic and the Neolithic. The term Epipaleolithic is often used synonymously, especially for outside northern Europe, and for the corresponding period in the Levant and Caucasus. The Mesolithic has different time spans in different parts of Eurasia. It refers to the final period of hunter-gatherer cultures in Europe and Western Asia, between the end of the Last Glacial Maximum and the Neolithic Revolution. In Europe it spans roughly 15,000 to 5,000 BP; in Southwest Asia (the Epipalaeolithic Near East) roughly 20,000 to 8,000 BP. The term is less used of areas further east, and not at all beyond Eurasia and North Africa.
The type of culture associated with the Mesolithic varies between areas, but it is associated with a decline in the group hunting of large animals in favour of a broader hunter-gatherer way of life, and the development of more sophisticated and typically smaller lithic tools and weapons than the heavy chipped equivalents typical of the Paleolithic. Depending on the region, some use of pottery and textiles may be found in sites allocated to the Mesolithic, but generally indications of agriculture are taken as marking transition into the Neolithic. The more permanent settlements tend to be close to the sea or inland waters offering a good supply of food. Mesolithic societies are not seen as very complex, and burials are fairly simple; grandiose burial mounds are another mark of the Neolithic.Orange slice
Orange slice is an early sickle blade element made out of flint. The flints are so called due to their shape, which resembles a segment of an Orange. The morphology was first recognized by J. Hamal-Nandrin and J. Servais in 1928, who called them "Quartier d'orange" in French. This sickle industry has no evidence of developed denticulation. Orange slices were used for harvesting plants at the start of the Neolithic revolution and were particularly prevalent in Lebanon where they were found alongside Heavy Neolithic axes and larger flint tools of the Qaraoun culture in and around Qaraoun in the south of the country. Sites where orange slices have been found include Mejdel Anjar I, Dakwe I and II, Habarjer III, Qaraoun I and II, Kefraya, and Beıdar Chamout. Orange slices were only found in large quantities around Qaraoun, where it is suggested they were part of a specialist Neolithic industry of the area.Outline of prehistoric technology
The following outline is provided as an overview of and topical guide to prehistoric technology.
Prehistoric technology – technology that predates recorded history. History is the study of the past using written records; it is also the record itself. Anything prior to the first written accounts of history is prehistoric (meaning "before history"), including earlier technologies. About 2.5 million years before writing was developed, technology began with the earliest hominids who used stone tools, which they may have used to start fires, hunt, cut food, and bury their dead.Paleolithic diet
The Paleolithic diet, Paleo diet, caveman diet, or stone-age diet is a modern fad diet requiring the sole or predominant eating of foods presumed to have been available to humans during the Paleolithic era.The digestive abilities of anatomically modern humans, however, are different from those of pre-H. s. sapiens humans, which has been used to criticize the diet's core premise. During the 2.6 million year-long Paleolithic era, the highly variable climate and worldwide spread of human populations meant that humans were, by necessity, nutritionally adaptable. Supporters of the diet mistakenly presuppose that human digestion has remained essentially unchanged over time.While there is wide variability in the way the paleo diet is interpreted, the diet typically includes vegetables, fruits, nuts, roots, and meat and typically excludes foods such as dairy products, grains, sugar, legumes, processed oils, salt, alcohol, or coffee. The diet is based on avoiding not just processed foods, but rather the foods that humans began eating after the Neolithic Revolution when humans transitioned from hunter-gatherer lifestyles to settled agriculture. The ideas behind the diet can be traced to Walter L. Voegtlin during the 1970s. In the 21st century, the paleo diet was popularized in the best-selling books of Loren Cordain.The paleo diet is promoted as a way of improving health. There is some evidence that following this diet may lead to improvements in terms of body composition and metabolic effects compared with the typical Western diet or compared with diets recommended by national nutritional guidelines. There is no good evidence that the diet helps with weight loss, other than through the normal mechanisms of calorie restriction. Following the paleo diet can lead to nutritional deficiencies such as an inadequate calcium intake, and side effects can include weakness, diarrhea, and headaches.Plain of Zgharta
The Plain of Zgharta (or Plain of Zghorta) is a Heavy Neolithic archaeological site approximately 7 kilometres (4.3 mi) east and southeast of Tripoli in Lebanon. It has historically been a region known for growing sumptuous olives owing to early Quaternary, cemented fluvatile deposits that cover the land beneath the topsoil (known as the Conglomerates of Zgharta or the Conglomerates of Zghorta). The site was documented by R. Wetzel and J. Haller in 1945 who discuss surface finds of several large flakes and atypical bifaces from this area and ended up giving them a very improabable label of Mousterian. Lorraine Copeland deduced the likelihood that these pieces were Gigantolithic tools, once used by the Qaraoun culture to chop down Cedars of Lebanon to start the Neolithic Revolution.Prehistoric Caucasus
The Caucasus region, on the gateway between Southwest Asia, Europe and Central Asia, plays a pivotal role in the peopling of Eurasia,
possibly as early as during the Homo erectus expansion to Eurasia,
in the Upper Paleolithic peopling of Europe,
and again in the re-peopling Mesolithic Europe following the Last Glacial Maximum, and in the expansion associated with the Neolithic Revolution.Prehistoric technology
Prehistoric technology is technology that predates recorded history. History is the study of the past using written records. Anything prior to the first written accounts of history is prehistoric, including earlier technologies. About 2.5 million years before writing was developed, technology began with the earliest hominids who used stone tools, which they may have used to start fires, hunt, and bury their dead.
There are several factors that made the evolution of prehistoric technology possible or necessary. One of the key factors is behavioral modernity of the highly developed brain of Homo sapiens capable of abstract reasoning, language, introspection, and problem solving. The advent of agriculture resulted in lifestyle changes from nomadic lifestyles to ones lived in homes, with domesticated animals, and land farmed using more varied and sophisticated tools. Art, architecture, music and religion evolved over the course of the prehistoric periods.Small-scale agriculture
Small-scale agriculture has been practiced ever since the Neolithic Revolution. More recently it is an alternative to factory farming or more broadly, intensive agriculture or unsustainable farming methods that are prevalent in primarily first world countries. Environmental Health Perspectives has noted that "Sustainable agriculture is not merely a package of prescribed methods. More important, it is a change in mind set whereby agriculture acknowledges its dependence on a finite natural resource base--including the finite quality of fossil fuel energy that is now a critical component of conventional farming systems." Small-scale agriculture includes a number of sustainable agriculture practices such as:
organic farming, which may follow rules and regulations set by International Federation of Organic Agriculture Movements (IFOAM)
permaculture, which provides a holistic methodology for farm design
arable land use, arable land (from Latin arare, to plough ) is a form of agricultural land use, meaning land that can be (and is) used for growing crops. David Ricardo incorporated the idea of arable land into economic theory.
non-arable land use
pastoral, pastoral refers to the lifestyle of shepherds and pastoralists, moving livestock around larger areas of land according to seasons and availability of water and feed.
biodynamic agriculture was developed by Rudolf Steiner, which consists of using herbal and homeopathic preparations for the cow dung/manure that is used extensively on the crops for fertilizer.The methods of food sustainability and economics are hotly debated. This is a question between agricultural economics and the draining of the largely unaccounted natural capital.Tahunian
The Tahunian is variously referred to as an archaeological culture, flint industry and period of the Palestinian Stone Age around Wadi Tahuna near Bethlehem. It was discovered and termed by Denis Buzy during excavations in 1928.Due to the early date and problems with the stratigraphy of the excavations at Wadi Tahuna, a great deal of debate has been put forward regarding the definition and position of the Tahunian within the sequences of Mesolithic, Epipaleolithic, Natufian, Khiamian, Heavy Neolithic, Pre-Pottery Neolithic A, Pre-Pottery Neolithic B and Neolithic and its relation to other Neolithic cultures such as the Qaraoun culture. In the search for naming conventions for the culture that started the Neolithic Revolution, this has reduced Avi Gopher to calling it a "Tahunian Pandora's box", resulting in offshoots in terminology such as Proto-Tahunian. It is no longer widely used but would appear to be an early PPNB culture of the Levantine corridor of around 8800 BC according to the ASPRO chronology.Technological revolution
A technological revolution is a period in which one or more technologies is replaced by another technology in a short amount of time. It is an era of accelerated technological progress characterized by new innovations whose rapid application and diffusion cause an abrupt change in society.Wadi Sallah
Wadi Sallah is a branch of the Wadi Fa'rah where a small cave is located in the Palestinian Tubas Governorate in the northeastern West Bank, located five kilometers southwest of Tubas. The cave was discovered and excavated by Francis Turville-Petre between 1925 and 1926. It contained an occupational Heavy Neolithic archaeological site of the Qaraoun culture. This culture was without pottery and typically used large axes for chopping lumber, cutting wood and felling trees such as the cedars of Lebanon in preparation for the domestication of emmer wheat and the Neolithic Revolution. Levels II and III of Turville-Petre's excavations revealed deposits of flints and potsherds. The pottery was later in date that the Heavy Neolithic material, which included heavy blades (picks, adzes, borers and flake scrapers), massive flake scrapers, and pieces with denticulation, all similar to those found at Shemouniyeh and Wadi Fa'rah. Several arrowheads were also found that were pressure flaked, generally tanged and leaf-shaped. One of these was of the Amuq 2 type.
