Agricultural and urban revolutions

How did life change for people after the Agricultural Revolution? What were the benefits of farming?

Ancient grains Map of the world showing approximate centers of origin of agriculture and its spread in prehistory: 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.

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.

The most prominent of these are: However, today this theory has little support amongst archaeologists because subsequent climate data suggests that the region was getting wetter rather than drier.

This required assembling large quantities of food, which drove agricultural technology. The Demographic theories proposed by Carl Sauer [19] and adapted by Lewis Binford [20] and Kent Flannery posit an increasingly sedentary population that expanded up to the carrying capacity of the local environment and required more food than could be gathered.

Various social and economic factors helped drive the need for food. Starting with domestication by protection of wild plants, it led to specialization of location and then full-fledged domestication.

Peter RichersonRobert Boydand Robert Bettinger [22] make a case for the development of agriculture coinciding with an increasingly stable climate at the beginning of the Holocene. The postulated Younger Dryas impact eventclaimed to be in part responsible for megafauna extinction and ending the last glacial periodcould have provided circumstances that required the evolution of agricultural societies for humanity to survive.

Leonid Grinin argues that whatever plants were cultivated, the independent invention of agriculture always took place in special natural environments e. It is supposed that the cultivation of cereals started somewhere in the Near East: So Grinin dates the beginning of the agricultural revolution within the interval 12, to 9, 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.

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 over 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.

He noted that the full range of domesticated animals goatssheepcattle and pigs were not found until the sixth millennium 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 Peninsulaespecially where wadis carrying Pleistocene rainfall runoff flowed.

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; years of harvesting selected for strains that retained their edible seeds longer.

Several plant species, the "pioneer crops" or Neolithic founder cropswere identified by Daniel Zoharywho highlighted the importance of the three cerealsand suggested that domestication of flaxpeaschickpeasbitter 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.

Selectively propagated figswild barley and wild oats were cultivated at the early Neolithic site of Gilgal Iwhere in [31] archaeologists found caches of seeds of each in quantities too large to be accounted for even by intensive gatheringat strata datable to c.

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, 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.

The Fertile Crescent region of Southwest Asia is the centre of domestication for three cereals einkorn wheat, emmer wheat and barleyfour legumes lentil, pea, bitter vetch and chickpeaand flax.

Domestication was a slow process involving multiple sites for each crop. They were cultivated around BC. 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, BP.

Bananas and plantainswhich were first domesticated in Southeast Asiamost likely Papua New Guineawere re-domesticated in Africa possibly as early as 5, years ago. Asian yams and taro were also cultivated in Africa. In addition, khatensetenoogteff and finger millet were also domesticated in the Ethiopian highlands.

Crops domesticated in the Sahel region include sorghum and pearl millet.(theories for agricultural revolution) hunting & gathering was so productive it led to increase in pop. led to more people needing food people in marginal areas decided to domesticate domestication is gradual and they could not predict which animals/plants could be domesticated.

Urban revolution, in anthropology and archaeology, the processes by which agricultural village societies developed into socially, economically, and politically complex urban societies. The term urban revolution was introduced by . The term Neolithic Revolution was coined in by V.

The chapter then moves on to a discussion of the critical role of governments in choosing the appropriate combinations of monetary, fiscal, trade, investment and social policies to create an economic environment that is conducive to the attainment of food security. 2) There are 3 Agricultural revolutions that changed plombier-nemours.com First Agricultural Revolution was the transition from hunting and gathering to planting and sustaining.

The Second Agricultural Revolution increased the productivity of farming through mechanization and access to market areas due to better transportation.
