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 and a reliable food supply.
How did the development of farming affect early humans?
When early humans began farming, they were able to produce enough food that they no longer had to migrate to their food source. This meant they could build permanent structures, and develop villages, towns, and eventually even cities. Closely connected to the rise of settled societies was an increase in population.
How did early societies prepare fields for agriculture?
For example, most early societies prepared fields for agriculture using slash and burn techniques, which basically means clearing out all existing vegetation to make room for crops. In small societies, this works, but for larger populations, slash and burn techniques can quickly ruin the soil, leading to erosion and other problems.
How did the spread of agriculture affect the world?
As food was grown and stored more efficiently, populations increased and settlements grew larger, creating both the incentive and the means to produce even more food on more land. Agriculture spread at different rates, depending on climate and geography.
How did the Industrial Revolution affect the agriculture industry?
Since every moment no longer had to be spent on food, people could specialize in occupations, such as that of the potter, baker, metallurgist, and engineer, that supported agriculture. These new occupations, in turn, increased population density and food production even more.
How did the Agricultural Revolution impact early humans?
The agricultural revolution had a variety of consequences for humans. It has been linked to everything from societal inequality—a result of humans’ increased dependence on the land and fears of scarcity—to a decline in nutrition and a rise in infectious diseases contracted from domesticated animals.
What was the biggest impact of the agricultural revolution on early societies?
Farming began a process of intensification, which meant that many more people could be sustained in a given land area since more calories could be produced per acre. As a result, the world population rapidly rose. Between 10,000 and 1000 BCE, the population of the world went from about 6 million to about 120 million.
What is the main impact 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.
How did Agricultural Revolution change and affect the structure of the society?
The increase in agricultural production and technological advancements during the Agricultural Revolution contributed to unprecedented population growth and new agricultural practices, triggering such phenomena as rural-to-urban migration, development of a coherent and loosely regulated agricultural market, and …
Why was agriculture important to the development of civilization?
Humans invented agriculture. Farming enabled people to grow all the food they needed in one place, with a much smaller group of people. This led to massive population growth, creating cities and trade.
Where did agriculture begin?
People began farming at different times in different parts of the world. Around 8500 b.c. hunter-gatherers in the area of southwest Asia known as the Fertile Crescent began to cultivate wild grains and domesticate animals. One thousand years later, people in northern and southern China were growing rice and millet and raising pigs. Archeological evidence shows that crops were planted in Central America as early as 7000 b.c., and around 3500 b.c. in the Andes mountains and Amazon river basin of South America. Farmers in Africa began growing crops around 5000 b.c. Three thousand years later, native Americans in the eastern United States planted a few crops, but still depended on hunting and gathering. As agriculture evolved in these locations, so did the social, economic, and cultural practices that led to what is known as civilization.
What were the first crops that were domesticated in the eastern United States?
The only crops domesticated in the eastern United States were squash and a few seed plants.
What were the first crops in the world?
Their first crops were emmer wheat and barley, which were high in protein and easy to domesticate compared to plants native to other parts of the world. Cultivated emmer wheat, for example, is very similar to its wild ancestor, while it took thousands of years for modern corn to evolve from its half-inch-long ancestor.
What were the climates of the fertile crescent?
The climate and geography of the Fertile Crescent were varied, ranging from valleys to mountains and from deserts to riverbeds. In addition to supporting a variety of plant life, this diversity supported a variety of mammals.
Why did people settle in the fertile crescent?
For the thousands of years before plants and animals were domesticated, people roved in small bands, foraging for enough food to stay alive. Because of the abundance of wild foods in the Fertile Crescent, hunter-gatherers settled there permanently.
What tools did the hunter-gatherers make?
The hunter-gatherers of the Fertile Crescent and China had been making tools from stone, wood, bone, and woven grass for thousands of years. Once farming took hold, people improved their tools so they could plant, harvest, and store crops more efficiently.
Why did animals evolve?
Animals also evolved in response to their new environments, some becoming larger and others smaller. The first domesticated animal was the dog, which was bred for hunting and food in several places around the world.
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.
What is the meaning of “agriculture”?
agriculture. Noun. the art and science of cultivating land for growing crops (farming) or raising livestock (ranching). annual plant. Noun. plant with a life cycle of no more than one year, and often much less. barley. Noun. grass cultivated as a grain.
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. 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, …
What were the effects of the ice age on the Near East?
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.
Where did the wild produce originate?
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. Though the transition from wild harvesting was gradual, the switch from a nomadic to a settled way of life is marked by the appearance of early Neolithic villages with homes equipped with grinding stones for processing grain.
When did rice and millet farming start?
The origins of rice and millet farming date to around 6,000 B.C.E.
Where did early agricultural societies develop?
In the Old World, settled life developed on the higher ground from Iran to Anatolia and the Levant and in China in the semiarid loess plains and the humid Yangtze valley.
What was the agricultural produce of the Temple?
Agricultural produce was allocated to temple personnel in return for their services, to important people in the community, and to small farmers. The land was cultivated by teams of oxen pulling light unwheeled plows, and the grain was harvested with sickles in the spring.
What was the main crop of Sumer?
Sumer’s Early Dynastic Phase began about 5000 bp, a century or so after the development of a nuanced writing system based on the Sumerian language. Barley was the main crop, but wheat, flax ( Linum species), dates ( Phoenix species), apples ( Malus species), plums ( Prunus species), and grapes ( Vitaceae species) were also grown.
How were oxen and onagers drawn?
They were drawn by oxen or onagers (wild asses) that were harnessed by collars, yokes, and headstalls and controlled by reins and a ring through the nose or upper lip and a strap under the jaw. As many as four animals, harnessed abreast to a central pole, pulled a wagon.
In A Nutshell
Generally, we think of the development of agriculture as a good thing. But recent research shows that with the lifestyle changes that came along with farming and the dietary changes made when we became less dependent on meat, we started to devolve.
The Whole Bushel
The switch from a society of hunter-gatherers to one largely based in agricultural has long been considered one of the great turning points in humanity’s history.

Why is it important to consider the rapid physiological increases in human stature during the 20th century?
Some economists and other scientists are using the rapid physiological increases in human stature during the 20th century as a key indicator of better health. “I think it’s important to consider what exactly ‘good health’ means,” Mummert says.
Is producing food beneficial?
We tend to think that producing food is always beneficial, but the picture is much more complex than that,” says Emory anthropologist George Armelagos, co-author of the review. “Humans paid a heavy biological cost for agriculture, especially when it came to the variety of nutrients.
Why is it so hard to meet the demand for accelerated agricultural productivity?
The reasons for this have to do with ecological factors. Global climate change is destabilizing many of the natural processes that make modern agriculture possible.
How do cattle damage soil?
Cattle and other large grazing animals can even damage soil by trampling on it. Bare, compacted land can bring about soil erosion and destruction of topsoil quality due to the runoff of nutrients. These and other impacts can destabilize a variety of fragile ecosystems and wildlife habitats. Chemical Fertilizer.
What is the effect of nitrogen on soil?
In addition, fertilizer application in soil leads to the formation and release of nitrous oxide, one of the most harmful greenhouse gases.
How does irrigation affect water?
Irrigation causes increases in water evaporation, impacting both surface air temperature and pressure as well as atmospheric moisture conditions . Recent studies have confirmed that cropland irrigation can influence rainfall patterns not only over the irrigated area but even thousands of miles away.
What is irrigation related to?
Irrigation has also been connected to the erosion of coastlines and other kinds of long-term ecological and habitat destruction. A huge amount of agricultural territory is used primarily as pasture for cattle and other livestock.
What causes algae blooms in China?
Nutrient pollution is a causal factor in toxic algae blooms affecting lakes in China, the United States, and elsewhere. As excessive amounts of organic matter decompose in aquatic environments, they can bring about oxygen depletion and create “dead zones” within bodies of water, where nothing can survive.
What are the consequences of irrigation?
One of the most obvious consequences is the depletion of aquifers, river systems, and downstream ground water. However, there are a number of other negative effects related to irrigation.
