Neolithic Revolution

• 1. Origins And Timeline

  ›

  The Neolithic Revolution began approximately 12,000 years ago in the Fertile Crescent. This period marked a wide-scale transition from egalitarian hunter-gatherer lifestyles to settled agricultural communities. Archaeological data indicate that food-producing domestication of wild animals and plants happened independently in separate locations worldwide. The process started after the end of the last Ice Age around 11,700 years ago. Climate changes made vast areas flooded due to sudden rises in sea levels. These environmental shifts forced human groups to adapt or perish. Some researchers argue this catastrophe formed the background for global flood myths. Rapid population increases followed these initial adaptations. Conflicts over territories and resource overuse became common consequences. Communities developed cultural measures to resolve these issues. The transition was not linear but governed by trial-and-error principles similar to Darwinian laws.

• 2. Domestication Processes

  ›

  Human activity resulted in selective breeding of cereal grasses beginning around 9,000 BP. Early crops included emmer, einkorn, and barley. Plants with traits like small seeds or bitter taste were seen as undesirable. Spontaneous selection favored strains that retained edible seeds longer during harvest. Daniel Zohary identified wheat, barley, and rye as pioneer crops. Flax, peas, chickpeas, bitter vetch, and lentils came later. Experiments showed domestication occurred over periods between 20 and 200 years. Rye tried and abandoned in Neolithic Anatolia later succeeded in Europe thousands of years afterward. Wild lentils presented dormancy problems until early Neolithic sites like Jerf el Ahmar broke them. Figs, wild barley, and wild oats cultivated at Gilgal I produced seed caches too large for gathering alone. Irrigation techniques traced back to the 6th millennium BCE in Khuzistan enabled surplus storage. Granaries allowed villages to store seeds longer than mobile groups could manage.

  ›

  Neolithic material culture spread from Southwest Asia into Europe via western Anatolia. All European Neolithic sites contain plants and animals originally domesticated in Southwest Asia. Genetic data suggest no independent animal domestication occurred in Neolithic Europe. Broomcorn millet was the only domesticate not originating there. The diffusion across Europe took about 2,500 years spanning 8500 to 6000 BP. Baltic regions were penetrated around 5500 BP with delays in settling Pannonian plains. Mesolithic and Neolithic populations lived side by side for as much as a millennium in many areas. Carbon-14 evidence shows linear relationships between site age and distance from Near Eastern sources. Average spread speeds reached approximately one kilometer per year. Agricultural practices originated 10,000 years ago in the Fertile Crescent before rapidly expanding. First farmers entered Europe following maritime routes through Cyprus and Aegean Islands. Southeast Asian rice cultivation technology traveled to Island Southeast Asia and Oceania. Austronesians carried these technologies to Madagascar and Comoros during the first millennium CE.

  Reliance on limited staple crops adversely affected health despite food abundance. Maize domesticated in the Americas provided starch but lacked iron and essential amino acids like lysine. Exchange of parasites, bacteria, and viruses between humans and livestock created new diseases. Densely populated areas accumulated human and animal waste serving as infection sources. Fertilizers promoted insect proliferation while grain storage attracted rodents. Hunter-gatherer diets remained well-balanced though dependent on seasonal availability. Nutritional standards of growing Neolithic populations proved inferior to those of foragers. Transition to cereal-based diets caused reductions in life expectancy and stature. Infant mortality increased alongside infectious disease development. Chronic inflammatory or degenerative diseases emerged including obesity and type two diabetes. Average height for Europeans dropped significantly and did not return to pre-Neolithic levels until the twentieth century. Carious teeth frequency increased with slower childhood growth rates. Inadequate sanitary practices explained rising deaths following the revolution. Diseases jumped from animals to humans including influenza, smallpox, and measles.

• 5. Social Stratification

  ›

  Food surpluses enabled population growth impossible under hunter-gatherer lifestyles. Specialized workers developed within increasingly complex societies. Social elites emerged who were not engaged in agriculture yet dominated communities. Decision-making became monopolized by these ruling groups. Larger societies made diverse governance models more feasible. Agriculture brought deep social divisions encouraging gender inequality. Mothers could raise older children concurrently with younger ones due to available milk and grains. Roles within society became more restrictive through religious conditioning. Progression from polytheism to monotheism crystallized this process. Political organizations formed as cross-group alliances among previously autonomous communities. Egalitarian hunter-gatherers founded proto-states like three male groups around Enlil Anu Enki. Hierarchies between superior and inferior groups proved difficult to assume initially. Specialized professions gradually led to power imbalances over time. Centralized administrations and specialized crafts emerged alongside hierarchical ideologies. Monumental art proclaimed founder power depicting them as gods. Trade and military operations expanded alongside depersonalized knowledge systems.

  ›

  V. Gordon Childe invented the term Neolithic Revolution in his 1936 book Man Makes Himself. The Oasis Theory proposed by Raphael Pumpelly in 1908 claimed drier climates forced community contraction. Subsequent climate data suggests regions were getting wetter rather than drier. Robert John Braidwood's Hilly Flanks hypothesis suggested agriculture began where fertile land supported domestication varieties. Brian Hayden's Feasting model argued ostentatious displays of power drove agricultural technology development. Demographic theories posited expanding populations reached local carrying capacity requiring more food. Evolutionary theories considered agriculture an adaptation of plants and humans starting with protection of wild plants. Peter Richerson, Robert Boyd, and Robert Bettinger linked development to increasingly stable Holocene climates. Leonid Grinin dates beginning within intervals from 12,000 to 9,000 BP though some cultivated plants are even older. Andrew Moore suggested origins over long periods possibly during Epipaleolithic times. Frank Hole noted no transition site had been found documenting shifts between immediate and delayed return social systems. Multiple independent inventions occurred in special natural environments like South-East Asia. No single cause explains all regional variations in agricultural emergence.
