Modern genetic techniques suggest that agriculture was largely spread by the slow migration of farmers themselves. It also seems clear that in some times and places, such as in northern South Asia, it was spread by the passing on of agricultural techniques to hunter-gatherers.
How did society change with agriculture?
The increased population densities of humans and livestock, clearance of forests for agriculture, and the transformation of soils means that the world we live in has become increasingly anthropogenic over the past few 1000 years (see Ellis et al 2013 “used planet”). Unlike Pleistocene hunter-gatherers, farming societies have transformed the surface of the earth, its atmospheric …
How did the spread of the agriculture affect trade?
How agriculture and domestication began. Agriculture has no single, simple origin. A wide variety of plants and animals have been independently domesticated at different times and in numerous places. The first agriculture appears to have developed at the closing of the last Pleistocene glacial period, or Ice Age (about 11,700 years ago). At that time temperatures warmed, glaciers …
How agriculture changed the world?
The hypothesis of the Neolithic demographic transition (NDT) postulates that sharp increases in birthrates occurred as populations in different parts of the world adopted sedentary lifestyles and …
How did early agriculture develop and spread?
· Genetic studies show that goats and other livestock accompanied the westward spread of agriculture into Europe, helping to revolutionize Stone Age society. While the extent to which farmers themselves migrated west remains a subject of debate, the dramatic impact of dairy farming on Europeans is clearly stamped in their DNA. Prior to the arrival of domestic …
How did the agricultural revolution spread?
During the 18th century, another Agricultural Revolution took place when European agriculture shifted from the techniques of the past. New patterns of crop rotation and livestock utilization paved the way for better crop yields, a greater diversity of wheat and vegetables and the ability to support more livestock.
Why did agriculture spread widely?
By actively managing their food supplies, agricultural societies were able to produce more food than hunter-foragers and support denser populations. Having a large population nearby made it worthwhile for farmers to grow more food than they needed for themselves, as they could trade this surplus for other goods.
When did agriculture start to spread?
around 12,000 years agoSometime around 12,000 years ago, our hunter-gatherer ancestors began trying their hand at farming. First, they grew wild varieties of crops like peas, lentils and barley and herded wild animals like goats and wild oxen.
Where did farming began and spread?
The earliest evidence of agricultural cultivation is from around 21,000 BC with the Ohalo II people on the shores of the Sea of Galilee. By around 9500 BC, the eight Neolithic founder crops – emmer wheat, einkorn wheat, hulled barley, peas, lentils, bitter vetch, chickpeas, and flax – were cultivated in the Levant.
How does agriculture spread around the world?
Modern genetic techniques suggest that agriculture was largely spread by the slow migration of farmers themselves. It also seems clear that in some times and places, such as in northern South Asia, it was spread by the passing on of agricultural techniques to hunter-gatherers.
How did the agriculture start?
Agricultural communities developed approximately 10,000 years ago when humans began to domesticate plants and animals. By establishing domesticity, families and larger groups were able to build communities and transition from a nomadic hunter-gatherer lifestyle dependent on foraging and hunting for survival.
Where did agriculture start?
Agriculture originated in a few small hubs around the world, but probably first in the Fertile Crescent, a region of the Near East including parts of modern-day Iraq, Syria, Lebanon, Israel and Jordan.
What were the effects of spread of agriculture?
Agriculture contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
When and where did agriculture first began?
Agriculture was developed at least 10,000 years ago, and it has undergone significant developments since the time of the earliest cultivation. Independent development of agriculture occurred in northern and southern China, Africa’s Sahel, New Guinea and several regions of the Americas.
How did early man discover agriculture?
Around 12,000 years ago, hunter-gatherers made an incredible discovery. They dug up the ground, scattered a few wild grains, and learned how to farm. Farming meant that early humans could control their sources of food by growing plants and raising animals.
When did agriculture begin?
The first agriculture appears to have developed at the closing of the last Pleistocene glacial period, or Ice Age (about 11,700 years ago).
Why do archaeologists study agricultural origins?
Because some resource management practices, such as intensively tending nondomesticated nut-bearing trees, bridge the boundary between foraging and farming, archaeologists investigating agricultural origins generally frame their work in terms of a continuum of subsistence practices.
Which Native American peoples developed complex methods to manage diverse sets of plants and animals?
For instance, Australian Aborigines and many of the Native American peoples of western North America developed complex methods to manage diverse sets of plants and animals, often including (but not limited to) cultivation.
Where do dogs get their meat from?
When considered in terms of food management, dogs may have been initially domesticated as hunting companions, while meat and milk could be obtained more reliably from herds of sheep, goats, reindeer, or cattle than from their wild counterparts or other game animals.
Does agriculture have to be a response to food scarcity?
Notably, agriculture does not appear to have developed in particularly impoverished settings; domestication does not seem to have been a response to food scarcity or deprivation. In fact, quite the opposite appears to be the case.
What was the early agricultural period?
Recent excavations of Early Agricultural period (1700 BC-AD 150) sites in southeastern Arizona show that the adoption of agriculture was a complicated and prolonged process. The application of a diet breadth model from optimal foraging theory suggests that the use of domesticated plants and irrigation to increase crop yields did not instigate an immediate decline in taxonomic diversity. Instead, cultigens were one component in a diverse foraging economy in which low-ranked plant and animal resources continued to be extensively used. This emerging model of the adoption of agriculture defies previous expectations. In comparison with Early Ceramic period (AD 150-650) and Hohokam Pioneer, Colonial, and Sedentary periods (AD 650-1150), the Early Agricultural period subsistence economy is best described as a mixed foraging and cultivation economy. Changes in the subsistence economy with increased dependence on maize were delayed until the Early Ceramic period, when the advent of high-quality ceramic containers reduced yield losses in storage, resulting in higher return rates and reduced risk from agricultural production. The fact that the mixed foraging and farming economy endured for at least 1350 years challenges the idea that the period of initial agriculture constitutes a “transitional” episode “from foraging to farming”.
What are the archaeological remains of early farmers?
Archaeological remains of the early farmers of southeastern Arizona (Figure 3.1) have been studied for more than six decades. Over that time-span, knowledge of their site types, subsistence strategies, settlement patterns, material cultures, and chronologies has grown through initial explorations, research expeditions, and cultural resource management projects. An explosion of discoveries in this region since the 1980s has pushed back the earliest dates in the Southwest for agriculture, canals, ceramics, cemeteries, villages, and possibly the bow and arrow. Concurrently, ideas about the circumstances and consequences of the introduction of agriculture to the region, who the first farmers were, and how their societies were different from Archaic hunting and gathering societies have evolved in relation to the sequence of archaeological discoveries, the development of new dating techniques, and the progression of Americanist and Southwesternist research interests and approaches to archaeological interpretation. However, some perennial questions remain unanswered, while many new questions have emerged. This chapter begins by describing the current landscape and climate of southeastern Arizona, the environmental changes at the beginning of the late Holocene that set the stage for the transition to agriculture in this region, and the environmental variation across the region that led to alternative adaptations in the western and eastern areas. It then reviews the history of research, the conventional wisdoms that held sway for decades, the changing chronological terms and subdivisions, and recent discoveries. It concludes with discussions of current questions about this first agricultural frontier north of Mexico.
What is the book “First Farmers” about?
The book contains a central theory about the relationships between increasing dependence upon food production, human demography, and population dispersal with farming cultures and languages in train. In it, I evaluate data from archaeology, linguistics, and genetics as independent lines of evidence focused on three central questions: why did farming societies come into existence in prehistory; where, when, and how did they originate in geographical terms; and by which mechanisms and in which directions, did they spread? Concerning the latter question, which will be the main focus of this chapter, I infer that increasing dependence on food production led to upward trends in population density, and ultimately to population dispersal as early farmers came to depend more and more upon agriculture and animal husbandry for their subsistence, in a world that was still very much the preserve of lower-density hunter–gatherers and still unravaged by the high-population-density diseases of more recent history. However, agricultural dependence was not necessarily an instant result of agricultural origin, and in some cases the two might have been separated across several millennia in time by a period of pre-domestication cultivation and husbandry, as documented by current research in the Levant and China (see Chapters 4, 5, and 9, this volume).
Where did the long distance migration occur?
Long-distance human migration across the Pacific Ocean occurred during the late Holocene and originated almost entirely in the west. As prevailing tradewinds blow from the east, the mechanisms of prehistoric seafaring have been debated since the sixteenth century. Inadequacies in propositions of accidental or opportunistic drifting on occasional westerlies were exposed by early computer simulation. Experimental voyaging in large, fast, weatherly (windward-sailing) double-canoes, together with computer simulation incorporating canoe performance data and modern, averaged, wind conditions, has supported the traditional notion of intentional passage-making in a widely accepted hypothesis of upwind migration by strategic voyaging. The critical assumption that maritime technology and sailing conditions were effectively the same prehistorically as in the historical and modern records is, however, open to question. We propose here that maritime technology during the late-Holocene migrations did not permit windward sailing, and show that the episodic pattern of initial island colonization, which is disclosed in recent archaeological data, matches periods of reversal in wind direction toward westerlies, as inferred from the millennial-scale history of ENSO (El Niño-Southern Oscillation).
When did the Austronesian people move to the Philippines?
The chronological focus is mainly on the period between 2500 and 1000 bc. These three disciplines in combination make a migration of Austronesian-speaking communities a more likely conclusion than independent movements of languages, genes and items of material culture. This implies that a non-exclusive cultural tradition that can be defined archaeologically was transmitted through space and time via inheritance, and render insufficient all explanations for Austronesian patterning that are based entirely on interaction models without migration.
Why did people start farming?
In the Near East, for example, it’s thought that climatic changes at the end of the last ice age brought seasonal conditions that favored annual plants like wild cereals. Elsewhere, such as in East Asia, increased pressure on natural food resources may have forced people to find homegrown solutions. But whatever the reasons for its independent origins, farming sowed the seeds for the modern age.
What was the farming revolution?
Taking root around 12,000 years ago, agriculture triggered such a change in society and the way in which people lived that its development has been dubbed the ” Neolithic Revolution.”. Traditional hunter-gatherer lifestyles, followed by humans since their evolution, were swept aside in favor of permanent settlements …
What mutation occurred during the spread of farming into southeastern Europe?
But at some point during the spread of farming into southeastern Europe, a mutation occurred for lactose tolerance that increased in frequency through natural selection thanks to the nourishing benefits of milk.

The wild progenitors of crops including wheat, barley and peas are traced to the Near East region. Cereals were grown in Syria as long as 9,000 years ago, while figs were cultivated even earlier; prehistoric seedless fruits discovered in the Jordan Valley suggest fig trees were being planted some 11,300 years ago.
How long ago did goats come to Europe?
Dates for the domestication of these animals range from between 13,000 to 10,000 years ago.

Where did agriculture originate?
By 8000 BC, farming was entrenched on the banks of the Nile. About this time, agriculture was developed independently in the Far East, probably in China, with rice rather than wheat as the primary crop. Maize was domesticated from the wild grass teosinte in southern Mexico by 6700 BC.
How long ago did agriculture start?
Wild grains were collected and eaten from at least 105,000 years ago.
How did the Industrial Revolution affect agriculture?
Between the 17th century and the mid-19th century, Britain saw a large increase in agricultural productivity and net output. New agricultural practices like enclosure, mechanization, four-field crop rotation to maintain soil nutrients, and selective breeding enabled an unprecedented population growth to 5.7 million in 1750, freeing up a significant percentage of the workforce, and thereby helped drive the Industrial Revolution. The productivity of wheat went up from 19 US bushels (670 l; 150 US dry gal; 150 imp gal) per acre in 1720 to around 30 US bushels (1,100 l; 240 US dry gal; 230 imp gal) by 1840, marking a major turning point in history.
What are the social issues that modern agriculture has raised?
Modern agriculture has raised social, political, and environmental issues including overpopulation, water pollution, biofuels, genetically modified organisms, tariffs and farm subsidies. In response, organic farming developed in the twentieth century as an alternative to the use of synthetic pesticides.
How has agriculture changed since 1900?
Since 1900, agriculture in the developed nations, and to a lesser extent in the developing world, has seen large rises in productivity as human labour has been replaced by mechanization, and assisted by synthe tic fertilizers, pesticides, and selective breeding.
What were the crops that were introduced in the Middle Ages?
In the Middle Ages, both in the Islamic world and in Europe, agriculture was transformed with improved techniques and the diffusion of crop plants, including the introduction of sugar, rice, cotton and fruit trees such as the orange to Europe by way of Al-Andalus.
Why was clover important to agriculture?
The use of clover was especially important as the legume roots replenished soil nitrates. The mechanisation and rationalisation of agriculture was another important factor.

Where were the remains of the Pitted Ware found?
The researchers studied the remains from four humans, one found on an ancient farm in Gökhem parish, likely belonging to a member of the agricultural Funnel Beaker culture. Less than 250 miles away, a second set of remains from three humans were unearthed on the island of Gotland, from hunter-gatherers of the Pitted Ware culture.
Where did the Stone Age farmers migrate from?
By analyzing ancient human remains, scientists have revealed that Stone Age farmers in Europe likely migrated from south to north.

Interestingly, these ancient genomes don’t share many similarities with modern-day Swedes, despite their discovery and excavations in Sweden.
Where was farming first developed?
One of the oldest centers in the development of farming is located in the Fertile Crescent. Near Eastern populations adopted sedentism 11,000 years ago, developed the first villages and progressively started to cultivate and breed mammals. Three thousand years later the first farming communities reached Greece and Bulgaria through the Bosporus and also likely by sailing through the Mediterranean islands.
Where did the first agriculturalists live?
In contrast, researchers discovered that in northern Europe, the first agriculturalists keep using – for centuries – the same personal ornaments used by previous foraging communities. These people lived in regions that are now in the north of Germany and Poland, Denmark, Sweden, Norway, Estonia and a small part of western Russia.
When was the wave of advance theory first proposed?
The debate over the contribution cultural exchanges or population changes made to the spread of farming goes back to the 1970s. A study published by Ammerman and Cavalli-Sforza described for the first time the so-called “wave of advance” theory, which implied local growth of sedentary populations and their expansion into neighboring areas.
Was farming a linear process?
In the meanwhile, many researches have shown that the transition to farming was not a linear process. It was slowed down, stopped or abandoned several times in specific regions before being definitely successful all over Europe.
