Anarcho-primitivism

From Wikipedia, the free encyclopedia

Anarcho-primitivism is a political ideology that advocates a return to non-"civilized" ways of life through deindustrialization, abolition of the division of labor or specialization and abandonment of large-scale organization technologies. Anarcho-primitivists critique the origins and progress of the Industrial Revolution and industrial society. According to anarcho-primitivism, the shift from hunter-gatherer to agricultural subsistence during the Neolithic Revolution gave rise to coercion, social alienation and social stratification.

Many classical anarchists reject the critique of civilization while some such as Wolfi Landstreicher endorse the critique without considering themselves anarcho-primitivists. Anarcho-primitivists are distinguished by the focus on the praxis of achieving a feral state of being through "rewilding".

History

Origins

Walden by Henry David Thoreau, an influential early green-anarchist work

In the United States, anarchism started to have an ecological view mainly in the writings of Henry David Thoreau. In his book Walden, he advocates simple living and self-sufficiency among natural surroundings in resistance to the advancement of industrial civilization. "Many have seen in Thoreau one of the precursors of ecologism and anarcho-primitivism represented today by John Zerzan. For George Woodcock, this attitude can also be motivated by the idea of resistance to progress and the rejection of the increasing materialism that characterized North American society in the mid-19th century." Zerzan himself included the text "Excursions" (1863) by Thoreau in his edited compilation of anti-civilization writings called Against Civilization: Readings and Reflections from 1999.

In the late 19th century, anarchist naturism appeared as the union of anarchist and naturist philosophies. It mainly was important within individualist anarchist circles in Spain, France and Portugal. Important influences in it were Henry David Thoreau, Leo Tolstoy and Élisée Reclus. Anarcho-naturism advocated vegetarianism, free love, nudism and an ecological world view within anarchist groups and outside them.

Anarcho-naturism promoted an ecological worldview, small ecovillages, and most prominently nudism as a way to avoid the artificiality of the industrial mass society of modernity. Naturist individualist anarchists saw the individual in his biological, physical and psychological aspects and avoided and tried to eliminate social determinations. Their ideas were important in individualist anarchist circles in France but also in Spain where Federico Urales (pseudonym of Joan Montseny), promotes the ideas of Gravelle and Zisly in La Revista Blanca (1898–1905).

This tendency was strong enough as to call the attention of the CNTFAI in Spain. Daniel Guérin, in Anarchism: From Theory to Practice, reports how "Spanish anarcho-syndicalism had long been concerned to safeguard the autonomy of what it called "affinity groups". There were many adepts of naturism and vegetarianism among its members, especially among the poor peasants of the south. Both these ways of living were considered suitable for the transformation of the human being in preparation for a stateless society. At the Zaragoza congress, the members did not forget to consider the fate of groups of naturists and nudists, "unsuited to industrialization". As these groups would be unable to supply all their own needs, the Congress anticipated that their delegates to the meetings of the Confederation of communes would be able to negotiate special economic agreements with the other agricultural and industrial communes. On the eve of a vast, bloody, social transformation, the CNT did not think it foolish to try to meet the infinitely varied aspirations of individual human beings."

Recent themes

A primitive lifestyle living outside the Industrial Revoultion

Anarchists contribute to an anti-authoritarian push, which challenges all abstract power on a fundamental level, striving for egalitarian relationships and promoting communities based upon mutual aid. Primitivists, however, extend ideas of non-domination to all life, not just human life, going beyond the traditional anarchist's analysis. Using the work of anthropologists, primitivists look at the origins of civilization so as to understand what they are up against and how current society formed in order to inform a change in direction. Inspired by the Luddites, primitivists rekindle an anti-technological orientation. Insurrectionalists do not believe in waiting for critiques to be fine-tuned, instead spontaneously attacking civilization's current institutions.

Primitivists may owe much to the Situationists and their critique of the ideas in The Society of the Spectacle and alienation from a commodity-based society. Deep ecology informs the primitivist perspective with an understanding that the well-being of all life is linked to the awareness of the inherent worth and intrinsic value of the non-human world, independent of its economic value. Primitivists see deep ecology's appreciation for the richness and diversity of life as contributing to the realization that present human interference with the non-human world is coercive and excessive.

Bioregionalists bring the perspective of living within one's bioregion, and being intimately connected to the land, water, climate, plants, animals, and general patterns of their bioregion.

Some primitivists have been influenced by the various indigenous cultures. Primitivists attempt to learn and incorporate sustainable techniques for survival and healthier ways of interacting with life. Some are also inspired by the feral subculture, where people abandon domestication and have re-integrate themselves with the wild.

Some theorists posit that the fact that anarcho-primitivism has existed as a political ideology consistently for so long points to a dissatisfaction with civilization and a desire to return to nature felt across cultures and generations. They argue that the width of the divide between civilization and nature, or the perception thereof, is a factor that feeds the desire to destroy civilization, and by extension, supports the continued relevance of anarcho-primitivist thought.

Main concepts

"Anarchy is the order of the day among hunter-gatherers. Indeed, critics will ask why a small face-to-face group needs a government anyway. [...] If this is so we can go further and say that since the egalitarian hunting-gathering society is the oldest type of human society and prevailed for the longest period of time – over thousands of decades – then anarchy must be the oldest and one of the most enduring kinds of polity. Ten thousand years ago everyone was an anarchist."

Harold Barclay, American anthropologist

Some anarcho-primitivists state that prior to the advent of agriculture humans lived in small, nomadic bands which were socially, politically, and economically egalitarian. Being without hierarchy, these bands are sometimes viewed as embodying a form of anarchism.

Primitivists hold that following the emergence of agriculture the growing masses of humanity became evermore beholden to technology ("technoaddiction")  and abstract power structures arising from the division of labor and hierarchy. Primitivists disagree over what degree of horticulture might be present in an anarchist society, with some arguing that permaculture could have a role but others advocating a strictly hunter-gatherer subsistence.

Primitivism has drawn heavily upon cultural anthropology and archaeology. From the 1960s forward, societies once viewed as "barbaric" were reevaluated by academics, some of whom now hold that early humans lived in relative peace and prosperity in what has been called the "original affluent society". Frank Hole, an early-agriculture specialist, and Kent Flannery, a specialist in Mesoamerican civilization, have noted that, "No group on earth has more leisure time than hunters and gatherers, who spend it primarily on games, conversation and relaxing." Jared Diamond, in the article "The Worst Mistake in the History of the Human Race", said hunter-gatherers practice the most successful and longest-lasting life style in human history, in contrast with agriculture, which he described as a "mess" and that it is "unclear whether we can solve it". Based on evidence that life expectancy has decreased with the adoption of agriculture, the anthropologist Mark Nathan Cohen has called for the need to revise the traditional idea that civilization represents progress in human well-being.

Scholars such as Karl Polanyi and Marshall Sahlins characterized primitive societies as gift economies with "goods valued for their utility or beauty rather than cost; commodities exchanged more on the basis of need than of exchange value; distribution to the society at large without regard to labor that members have invested; labor performed without the idea of a wage in return or individual benefit, indeed largely without the notion of 'work' at all."

Civilization and violence

Anarcho-primitivists view civilization as the logic, institution, and physical apparatus of domestication, control, and domination. They focus primarily on the question of origins. Civilization is seen as the underlying problem or root of oppression, and they believe that civilization should therefore be dismantled or destroyed.

Anarcho-primitivists describe the rise of civilization as the shift over the past 10,000 years from an existence deeply connected to the web of life, to one psychologically separated from and attempting to control the rest of life. They state that prior to civilization, there generally existed ample leisure time, considerable gender equality and social equality, a non-destructive and uncontrolling approach to the natural world, the absence of organized violence, no mediating or formal institutions, and strong health and robustness. Anarcho-primitivists state that civilization inaugurated mass warfare, the subjugation of women, population growth, busy work, concepts of property, entrenched hierarchies, as well as encouraging the spread of diseases. They claim that civilization begins with and relies on an enforced renunciation of instinctual freedom and that it is impossible to reform away such a renunciation. Based on several anthropological references, they further state that hunter-gatherer societies are less susceptible to war, violence, and disease.

However, some – such as Lawrence Keely – contest this, citing that many tribe-based people are more prone to violence than developed states.

Domestication

Anarcho-primitivists, such as John Zerzan, define domestication as "the will to dominate animals and plants", claiming that domestication is "civilization's defining basis".

They also describe it as the process by which previously nomadic human populations shifted towards a sedentary or settled existence through agriculture and animal husbandry. They claim that this kind of domestication demands a totalitarian relationship with both the land and the plants and animals being domesticated. They say that whereas, in a state of wildness, all life shares and competes for resources, domestication destroys this balance. Domesticated landscape (e.g. pastoral lands/agricultural fields and, to a lesser degree, horticulture and gardening) ends the open sharing of resources; where "this was everyone's", it is now "mine". Anarcho-primitivists state that this notion of ownership laid the foundation for social hierarchy as property and power emerged. It also involved the destruction, enslavement, or assimilation of other groups of early people who did not make such a transition.

To primitivists, domestication enslaves both the domesticated species as well as the domesticators. Advances in the fields of psychology, anthropology, and sociology allow humans to quantify and objectify themselves, until they too become commodities.

Rewilding and reconnection

For most primitivist anarchists, rewilding and reconnecting with the earth is a life project. They state that it should not be limited to intellectual comprehension or the practice of primitive skills, but, instead, that it is a deep understanding of the pervasive ways in which we are domesticated, fractured, and dislocated from ourselves, each other, and the world. Rewilding is understood as having a physical component which involves reclaiming skills and developing methods for a sustainable co-existence, including how to feed, shelter, and heal ourselves with the plants, animals, and materials occurring naturally in our bioregions. It is also said to include the dismantling of the physical manifestations, apparatus, and infrastructure of civilization.

Rewilding is also described as having an emotional component, which involves healing ourselves and each other from what are perceived as 10,000-year-old wounds, learning how to live together in non-hierarchical and non-oppressive communities, and de-constructing the domesticating mindset in our social patterns. To the primitivist, "rewilding includes prioritizing direct experience and passion over mediation and alienation, re-thinking every dynamic and aspect of reality, connecting with our feral fury to defend our lives and to fight for a liberated existence, developing more trust in our intuition and being more connected to our instincts, and regaining the balance that has been virtually destroyed after thousands of years of patriarchal control and domestication. Rewilding is the process of becoming uncivilized."

Consumerism and mass society

Brian Sheppard asserts that anarcho-primitivism is not a form of anarchism at all. In Anarchism vs. Primitivism he says: "In recent decades, groups of quasi-religious mystics have begun equating the primitivism they advocate (rejection of science, rationality, and technology often lumped together under a blanket term "technology") with anarchism. In reality, the two have nothing to do with each other."

Andrew Flood agrees with this assertion and points out that primitivism clashes with what he identifies as the fundamental goal of anarchism: "the creation of a free mass society".

Primitivists do not believe that a "mass society" can be free. They believe industry and agriculture inevitably lead to hierarchy and alienation. They argue that the division of labor techno-industrial societies require to function forces people into reliance on factories and the labor of other specialists to produce their food, clothing, shelter, and other necessities and that this dependence forces them to remain a part of this society, whether they like it or not.

Critique of mechanical time and symbolic culture

Some anarcho-primitivists view the shift towards an increasingly symbolic culture as highly problematic in the sense that it separates us from direct interaction. Often the response to this, by those who assume that it means that primitivists prefer to completely eliminate all forms of symbolic culture, is something to the effect of, "So, you just want to grunt?" However, typically the critique regards the problems inherent within a form of communication and comprehension that relies primarily on symbolic thought at the expense (and even exclusion) of other sensual and unmediated means of comprehension. The emphasis on the symbolic is a departure from direct experience into mediated experience in the form of language, art, number, time, etc.

Anarcho-primitivists state that symbolic culture filters our entire perception through formal and informal symbols and separates us from direct and unmediated contact with reality. It goes beyond just giving things names, and extends to having an indirect relationship with a distorted image of the world that has passed through the lens of representation. It is debatable whether humans are "hard-wired" for symbolic thought, or if it developed as a cultural change or adaptation, but, according to anarcho-primitivists, the symbolic mode of expression and understanding is limited and deceptive, and over-dependence upon it leads to objectification, alienation, and perceptual tunnel vision. Many anarcho-primitivists promote and practice getting back in touch with and rekindling dormant and/or underutilized methods of interaction and cognition, such as touch and smell, as well as experimenting with and developing unique and personal modes of comprehension and expression.

Regarding those primitivists who have extended their critique of symbolic culture to language itself, Georgetown University professor Mark Lance describes this particular theory of primitivism as "literally insane, for proper communication is necessary to create within the box a means to destroy the box".

Criticism and counter-criticism

Notable critics of anarcho-primitivism include post-left anarchists Wolfi Landstreicher and Jason McQuinn, Ted Kaczynski (the "Unabomber"), and especially libertarian socialist Murray Bookchin, as seen in his polemical work entitled Social Anarchism or Lifestyle Anarchism.

Wording and semantics

Activist writer Derrick Jensen wrote in Walking on Water that he is often classified as a "Luddite" and "an anarcho-primitivist. Both of these labels fit well enough, I suppose." Others, too, have designated his work with the latter term; however, more recently, Jensen began to categorically reject the "primitivist" label, describing it as a "racist way to describe indigenous peoples". He prefers to be called "indigenist" or an "ally to the indigenous".

Hypocrisy

A common criticism is of hypocrisy, i.e. that people rejecting civilization typically maintain a civilized lifestyle themselves, often while still using the very industrial technology that they oppose in order to spread their message. Jensen counters that this criticism merely resorts to an ad hominem argument, attacking individuals but not the actual validity of their beliefs. He further responds that working to entirely avoid such hypocrisy is ineffective, self-serving, and a convenient misdirection of activist energies. Primitivist John Zerzan admits that living with this hypocrisy is a necessary evil for continuing to contribute to the larger intellectual conversation. Jason Godesky holds that the charge of hypocrisy is a generalization, affirming that "not all primitivists are against technology in and of itself; only some. Many primitivists hold a view that technology is ambiguous (...) So, the charge of hypocrisy only holds up if we extend the beliefs of some primitivists to all primitivists, or to primitivism itself."

Glorification of indigenous societies

Wolfi Landstreicher and Jason McQuinn, post-leftists, have both criticized the romanticized exaggerations of indigenous societies and the pseudoscientific (and even mystical) appeal to nature they perceive in anarcho-primitivist ideology and deep ecology. Zerzan has countered that the anarcho-primitivist view is not idealizing the indigenous, but rather "has been the mainstream view presented in anthropology and archaeology textbooks for the past few decades. It sounds utopian, but it's now the generally accepted paradigm".

Ted Kaczynski has also argued that certain anarcho-primitivists have exaggerated the short working week of primitive society, arguing that they only examine the process of food extraction and not the processing of food, creation of fire and childcare, which adds up to over 40 hours a week.

Criticism from social anarchists

Besides Murray Bookchin, many class struggle oriented and social anarchists criticize primitivism as offering "no way forwards in the struggle for a free society" and that "often its adherents end up undermining that struggle by attacking the very things, like mass organization, that are a requirement to win it". Other social anarchists have also argued that abandoning technology will have dangerous consequences, pointing out that around 50% of the population of the United Kingdom requires glasses and would be left severely impaired. Radioactive waste would need to be monitored for tens of thousands of years with high-tech equipment to prevent it leaking into ecosystems, that the millions of people who need regular treatment for illnesses would die and that the removal of books, recorded music, medical equipment, central heating and sanitation would result in a rapid dropping of the quality of life. Furthermore, social anarchists contend that without advanced agriculture the Earth's surface would not be able to support billions of people, meaning that building a primitivist society would require the death of billions.

Domestication

From Wikipedia, the free encyclopedia
 
Dogs and sheep were among the first animals to be domesticated.

Domestication is a sustained multi-generational relationship in which one group of organisms assumes a significant degree of influence over the reproduction and care of another group to secure a more predictable supply of resources from that second group. The domestication of plants and animals was a major cultural innovation ranked in importance with the conquest of fire, the manufacturing of tools, and the development of verbal language.

Charles Darwin recognized the small number of traits that made domestic species different from their wild ancestors. He was also the first to recognize the difference between conscious selective breeding in which humans directly select for desirable traits, and unconscious selection where traits evolve as a by-product of natural selection or from selection on other traits. There is a genetic difference between domestic and wild populations. There is also such a difference between the domestication traits that researchers believe to have been essential at the early stages of domestication, and the improvement traits that have appeared since the split between wild and domestic populations. Domestication traits are generally fixed within all domesticates, and were selected during the initial episode of domestication of that animal or plant, whereas improvement traits are present only in a proportion of domesticates, though they may be fixed in individual breeds or regional populations.

The dog was the first domesticated species, and was established across Eurasia before the end of the Late Pleistocene era, well before cultivation and before the domestication of other animals. The archaeological and genetic data suggest that long-term bidirectional gene flow between wild and domestic stocks – including donkeys, horses, New and Old World camelids, goats, sheep, and pigs – was common. Given its importance to humans and its value as a model of evolutionary and demographic change, domestication has attracted scientists from archaeology, paleontology, anthropology, botany, zoology, genetics, and the environmental sciences. Among birds, the major domestic species today is the chicken, important for meat and eggs, though economically valuable poultry include the turkey, guineafowl and numerous other species. Birds are also widely kept as cagebirds, from songbirds to parrots. The longest established invertebrate domesticates are the honey bee and the silkworm. Land snails are raised for food, while species from several phyla are kept for research, and others are bred for biological control.

The domestication of plants began at least 12,000 years ago with cereals in the Middle East, and the bottle gourd in Asia. Agriculture developed in at least 11 different centres around the world, domesticating different crops and animals.

Overview

Succulents like this jelly bean plant (Sedum rubrotinctum) need infrequent watering, making them convenient as houseplants.

Domestication, from the Latin domesticus, 'belonging to the house', is "a sustained multi-generational, mutualistic relationship in which one organism assumes a significant degree of influence over the reproduction and care of another organism in order to secure a more predictable supply of a resource of interest, and through which the partner organism gains advantage over individuals that remain outside this relationship, thereby benefitting and often increasing the fitness of both the domesticator and the target domesticate." This definition recognizes both the biological and the cultural components of the domestication process and the impacts on both humans and the domesticated animals and plants. All past definitions of domestication have included a relationship between humans with plants and animals, but their differences lay in who was considered as the lead partner in the relationship. This new definition recognizes a mutualistic relationship in which both partners gain benefits. Domestication has vastly enhanced the reproductive output of crop plants, livestock, and pets far beyond that of their wild progenitors. Domesticates have provided humans with resources that they could more predictably and securely control, move, and redistribute, which has been the advantage that had fueled a population explosion of the agro-pastoralists and their spread to all corners of the planet.

Houseplants and ornamentals are plants domesticated primarily for aesthetic enjoyment in and around the home, while those domesticated for large-scale food production are called crops. Domesticated plants deliberately altered or selected for special desirable characteristics are cultigens. Animals domesticated for home companionship are called pets, while those domesticated for food or work are known as livestock.

This biological mutualism is not restricted to humans with domestic crops and livestock but is well-documented in nonhuman species, especially among a number of social insect domesticators and their plant and animal domesticates, for example the ant–fungus mutualism that exists between leafcutter ants and certain fungi.

Domestication syndrome is the suite of phenotypic traits arising during domestication that distinguish crops from their wild ancestors. The term is also applied to vertebrate animals, and includes increased docility and tameness, coat color changes, reductions in tooth size, changes in craniofacial morphology, alterations in ear and tail form (e.g., floppy ears), more frequent and nonseasonal estrus cycles, alterations in adrenocorticotropic hormone levels, changed concentrations of several neurotransmitters, prolongations in juvenile behavior, and reductions in both total brain size and of particular brain regions.

Cause and timing

Evolution of temperatures in the postglacial period, after the Last Glacial Maximum, showing very low temperatures for the most part of the Younger Dryas, rapidly rising afterwards to reach the level of the warm Holocene, based on Greenland ice cores.

The domestication of animals and plants was triggered by the climatic and environmental changes that occurred after the peak of the Last Glacial Maximum around 21,000 years ago and which continue to this present day. These changes made obtaining food difficult. The first domesticate was the wolf (Canis lupus) at least 15,000 years ago. The Younger Dryas that occurred 12,900 years ago was a period of intense cold and aridity that put pressure on humans to intensify their foraging strategies. By the beginning of the Holocene from 11,700 years ago, favorable climatic conditions and increasing human populations led to small-scale animal and plant domestication, which allowed humans to augment the food that they were obtaining through hunter-gathering.

The Neolithic transition led to agricultural societies emerging in locations across Eurasia, North Africa, and South and Central America. In the Fertile Crescent 10,000-11,000 years ago, zooarchaeology indicates that goats, pigs, sheep, and taurine cattle were the first livestock to be domesticated. Two thousand years later, humped zebu cattle were domesticated in what is today Baluchistan in Pakistan. In East Asia 8,000 years ago, pigs were domesticated from wild boar that were genetically different from those found in the Fertile Crescent. The horse was domesticated on the Central Asian steppe 5,500 years ago. Both the chicken in Southeast Asia and the cat in Egypt were domesticated 4,000 years ago.

The sudden appearance of the domestic dog (Canis lupus familiaris) in the archaeological record then led to a rapid shift in the evolution, ecology, and demography of both humans and numerous species of animals and plants. It was followed by livestock and crop domestication, and the transition of humans from foraging to farming in different places and times across the planet. Around 10,000 YBP, a new way of life emerged for humans through the management and exploitation of plant and animal species, leading to higher-density populations in the centers of domestication, the expansion of agricultural economies, and the development of urban communities.

Animals

Theory

The domestication of animals is the mutual relationship between animals with the humans who have influence on their care and reproduction. Charles Darwin recognized the small number of traits that made domestic species different from their wild ancestors. He was also the first to recognize the difference between conscious selective breeding in which humans directly select for desirable traits, and unconscious selection where traits evolve as a by-product of natural selection or from selection on other traits.

There is a genetic difference between domestic and wild populations. There is also such a difference between the domestication traits that researchers believe to have been essential at the early stages of domestication, and the improvement traits that have appeared since the split between wild and domestic populations. Domestication traits are generally fixed within all domesticates, and were selected during the initial episode of domestication of that animal or plant, whereas improvement traits are present only in a proportion of domesticates, though they may be fixed in individual breeds or regional populations.

Domestication of animals should not be confused with taming. Taming is the conditioned behavioral modification of an individual animal, to reduce its natural avoidance of humans, and to tolerate the presence of humans. Domestication is the permanent genetic modification of a bred lineage that leads to an inherited predisposition to respond calmly to human presence.

Certain animal species, and certain individuals within those species, make better candidates for domestication than others because they exhibit certain behavioral characteristics:

  1. The size and organization of their social structure
  2. The availability and the degree of selectivity in their choice of mates
  3. The ease and speed with which the parents bond with their young, and the maturity and mobility of the young at birth
  4. The degree of flexibility in diet and habitat tolerance; and
  5. Responses to humans and new environments, including reduced flight response and reactivity to external stimuli.

Mammals

The beginnings of animal domestication involved a protracted coevolutionary process with multiple stages along different pathways. There are three proposed major pathways that most animal domesticates followed into domestication:

  1. commensals, adapted to a human niche (e.g., dogs, cats, fowl, possibly pigs);
  2. prey animals sought for food (e.g., sheep, goats, cattle, water buffalo, yak, pig, reindeer, llama and alpaca); and
  3. animals targeted for draft and non-food resources (e.g., horse, donkey, camel).

The dog was the first domesticant, and was established across Eurasia before the end of the Late Pleistocene era, well before cultivation and before the domestication of other animals. Humans did not intend to domesticate animals from either the commensal or prey pathways, or at least they did not envision a domesticated animal would result from it. In both of those cases, humans became entangled with these species as the relationship between them intensified, and humans' role in their survival and reproduction led gradually to formalised animal husbandry. Although the directed pathway proceeded from capture to taming, the other two pathways are not as goal-oriented, and archaeological records suggest that they took place over much longer time frames.

Unlike other domestic species which were primarily selected for production-related traits, dogs were initially selected for their behaviors. The archaeological and genetic data suggest that long-term bidirectional gene flow between wild and domestic stocks – including donkeys, horses, New and Old World camelids, goats, sheep, and pigs – was common. One study has concluded that human selection for domestic traits likely counteracted the homogenizing effect of gene flow from wild boars into pigs and created domestication islands in the genome. The same process may also apply to other domesticated animals.

Birds

The red junglefowl of Southeast Asia was domesticated, apparently for cockfighting, some 7,000 years ago.
 

Domesticated birds principally mean poultry, raised for meat and eggs: some Galliformes (chicken, turkey, guineafowl) and Anseriformes (waterfowl: duck, goose, swan). Also widely domesticated are cagebirds such as songbirds and parrots; these are kept both for pleasure and for use in research. The domestic pigeon has been used both for food and as a means of communication between far-flung places through the exploitation of the pigeon's homing instinct; research suggests it was domesticated as early as 10,000 years ago. Chicken fossils in China were dated 7,400 years ago. The chicken's wild ancestor is Gallus gallus, the red junglefowl of Southeast Asia. It appears to have been kept initially for cockfighting rather than for food.

Invertebrates

Two insects, the silkworm and the western honey bee, have been domesticated for over 5,000 years, often for commercial use. The silkworm is raised for the silk threads wound around its pupal cocoon; the western honey bee, for honey, and, lately, for pollination of crops.

Several other invertebrates have been domesticated, both terrestrial and aquatic, including some such as Drosophila melanogaster fruit flies and the freshwater cnidarian Hydra for research into genetics and physiology. Few have a long history of domestication. Most are used for food or other products such as shellac and cochineal. The phyla involved are Cnidaria, Platyhelminthes (for biological control), Annelida, Mollusca, Arthropoda (marine crustaceans as well as insects and spiders), and Echinodermata. While many marine molluscs are used for food, only a few have been domesticated, including squid, cuttlefish and octopus, all used in research on behaviour and neurology. Terrestrial snails in the genera Helix and Murex are raised for food. Several parasitic or parasitoidal insects including the fly Eucelatoria, the beetle Chrysolina, and the wasp Aphytis are raised for biological control. Conscious or unconscious artificial selection has many effects on species under domestication; variability can readily be lost by inbreeding, selection against undesired traits, or genetic drift, while in Drosophila, variability in eclosion time (when adults emerge) has increased.

Plants

The initial domestication of animals impacted most on the genes that controlled their behavior, but the initial domestication of plants impacted most on the genes that controlled their morphology (seed size, plant architecture, dispersal mechanisms) and their physiology (timing of germination or ripening).

The domestication of wheat provides an example. Wild wheat shatters and falls to the ground to reseed itself when ripe, but domesticated wheat stays on the stem for easier harvesting. This change was possible because of a random mutation in the wild populations at the beginning of wheat's cultivation. Wheat with this mutation was harvested more frequently and became the seed for the next crop. Therefore, without realizing, early farmers selected for this mutation. The result is domesticated wheat, which relies on farmers for its reproduction and dissemination.

History

Farmers with wheat and cattle – Ancient Egyptian art 3,400 years ago

The earliest human attempts at plant domestication occurred in the Middle East. There is early evidence for conscious cultivation and trait selection of plants by pre-Neolithic groups in Syria: grains of rye with domestic traits dated 13,000 years ago have been recovered from Abu Hureyra in Syria, but this appears to be a localised phenomenon resulting from cultivation of stands of wild rye, rather than a definitive step towards domestication.

The bottle gourd (Lagenaria siceraria) plant, used as a container before the advent of ceramic technology, appears to have been domesticated 10,000 years ago. The domesticated bottle gourd reached the Americas from Asia by 8,000 years ago, most likely due to the migration of peoples from Asia to America.

Cereal crops were first domesticated around 11,000 years ago in the Fertile Crescent in the Middle East. The first domesticated crops were generally annuals with large seeds or fruits. These included pulses such as peas and grains such as wheat. The Middle East was especially suited to these species; the dry-summer climate was conducive to the evolution of large-seeded annual plants, and the variety of elevations led to a great variety of species. As domestication took place humans began to move from a hunter-gatherer society to a settled agricultural society. This change would eventually lead, some 4000 to 5000 years later, to the first city states and eventually the rise of civilization itself.

Continued domestication was gradual, a process of intermittent trial and error, and often resulted in diverging traits and characteristics. Over time perennials and small trees including the apple and the olive were domesticated. Some plants, such as the macadamia nut and the pecan, were not domesticated until recently.

In other parts of the world very different species were domesticated. In the Americas squash, maize, beans, and perhaps manioc (also known as cassava) formed the core of the diet. In East Asia millet, rice, and soy were the most important crops. Some areas of the world such as Southern Africa, Australia, California and southern South America never saw local species domesticated.

Differences from wild plants

Domesticated plants may differ from their wild relatives in many ways, including

  • the way they spread to a more diverse environment and have a wider geographic range;
  • different ecological preference (sun, water, temperature, nutrients, etc. requirements), different disease susceptibility;
  • conversion from a perennial to annual;
  • loss of seed dormancy and photoperiodic controls;
  • simultaneous flower and fruit, double flowers;
  • a lack of shattering or scattering of seeds, or even loss of their dispersal mechanisms completely;
  • less efficient breeding system (e.g. lack normal pollinating organs, making human intervention a requirement), smaller seeds with lower success in the wild, or even complete sexual sterility (e.g. seedless fruits) and therefore only vegetative reproduction;
  • less defensive adaptations such as hairs, thorns, spines, and prickles, poison, protective coverings and sturdiness, rendering them more likely to be eaten by animals and pests unless cared by humans;
  • chemical composition, giving them better palatability (e.g. sugar content), better smell, and lower toxicity;
  • edible part larger, and easier separated from non-edible part (e.g. freestone fruit).

Traits that are being genetically improved

There are many challenges facing modern farmers, including climate change, pests, soil salinity, drought, and periods with limited sunlight.

Drought is one of the most serious challenges facing farmers today. With shifting climates comes shifting weather patterns, meaning that regions that could traditionally rely on a substantial amount of precipitation were, quite literally, left out to dry. In light of these conditions, drought resistance in major crop plants has become a clear priority. One method is to identify the genetic basis of drought resistance in naturally drought resistant plants, i.e. the Bambara groundnut. Next, transferring these advantages to otherwise vulnerable crop plants. Rice, which is one of the most vulnerable crops in terms of drought, has been successfully improved by the addition of the Barley hva1 gene into the genome using transgenetics. Drought resistance can also be improved through changes in a plant's root system architecture, such as a root orientation that maximizes water retention and nutrient uptake. There must be a continued focus on the efficient usage of available water on a planet that is expected to have a population in excess of nine-billion people by 2050.

Another specific area of genetic improvement for domesticated crops is the crop plant's uptake and utilization of soil potassium, an essential element for crop plants yield and overall quality. A plant's ability to effectively uptake potassium and utilize it efficiently is known as its potassium utilization efficiency. It has been suggested that first optimizing plant root architecture and then root potassium uptake activity may effectively improve plant potassium utilization efficiency.

Crop plants that are being genetically improved

Cereals, rice, wheat, corn, sorghum and barley, make up a huge amount of the global diet across all demographic and social scales. These cereal crop plants are all autogamous, i.e. self-fertilizing, which limits overall diversity in allelic combinations, and therefore adaptability to novel environments. To combat this issue the researchers suggest an "Island Model of Genomic Selection". By breaking a single large population of cereal crop plants into several smaller sub-populations which can receive "migrants" from the other subpopulations, new genetic combinations can be generated.

The Bambara groundnut is a durable crop plant that, like many underutilized crops, has received little attention in an agricultural sense. The Bambara Groundnut is drought resistant and is known to be able to grow in almost any soil conditions, no matter how impoverished an area may be. New genomic and transcriptomic approaches are allowing researchers to improve this relatively small-scale crop, as well as other large-scale crop plants. The reduction in cost, and wide availability of both microarray technology and Next Generation Sequencing have made it possible to analyze underutilized crops, like the groundnut, at genome-wide level. Not overlooking particular crops that don't appear to hold any value outside of the developing world will be key to not only overall crop improvement, but also to reducing the global dependency on only a few crop plants, which holds many intrinsic dangers to the global population's food supply.

Challenges facing genetic improvement

The semi-arid tropics, ranging from parts of North and South Africa, Asia especially in the South Pacific, all the way to Australia are notorious for being both economically destitute and agriculturally difficult to cultivate and farm effectively. Barriers include everything from lack of rainfall and diseases, to economic isolation and environmental irresponsibility. There is a large interest in the continued efforts, of the International Crops Research Institute for the Semi-Arid Tropics (ICRSAT) to improve staple foods. some mandated crops of ICRISAT include the groundnut, pigeonpea, chickpea, sorghum and pearl millet, which are the main staple foods for nearly one billion people in the semi-arid tropics. As part of the ICRISAT efforts, some wild plant breeds are being used to transfer genes to cultivated crops by interspecific hybridization involving modern methods of embryo rescue and tissue culture. One example of early success has been work to combat the very detrimental peanut clump virus

Transgenetic plants containing the coat protein gene for resistance against peanut clump virus have already been produced successfully. Another region threatened by food security are the Pacific Island Countries, which are disproportionally faced with the negative effects of climate change. The Pacific Islands are largely made up of a chain of small bodies of land, which obviously limits the amount of geographical area in which to farm. This leaves the region with only two viable options 1.) increase agricultural production or 2.) increase food importation. The latter of course runs into the issues of availability and economic feasibility, leaving only the first option as a viable means to solve the region's food crisis. It is much easier to misuse the limited resources remaining, as compared with solving the problem at its core.

Working with wild plants to improve domestics

Work has also has been focusing on improving domestic crops through the use of crop wild relatives. The amount and depth of genetic material available in crop wild relatives is larger than originally believed, and the range of plants involved, both wild and domestic, is ever expanding. Through the use of new biotechnological tools such as genome editing, cisgenesis/intragenesis, the transfer of genes between crossable donor species including hybrids, and other omic approaches.

Wild plants can be hybridized with crop plants to form perennial crops from annuals, increase yield, growth rate, and resistance to outside pressures like disease and drought. It is important to remember that these changes take significant lengths of time to achieve, sometimes even decades. However, the outcome can be extremely successful as is the case with a hybrid grass variant known as Kernza. Over the course of nearly three decades, work was done on an attempted hybridization between an already domesticated grass strain, and several of its wild relatives. The domesticated strain as was more uniform in its orientation, but the wild strains were larger and propagated faster. The resulting Kernza crop has traits from both progenitors: uniform orientation and a linearly vertical root system from the domesticated crop, along with increased size and rate of propagation from the wild relatives.

Fungi and micro-organisms

Button mushrooms are widely cultivated for food.

Several species of fungi have been domesticated for use directly as food, or in fermentation to produce foods and drugs. The white button mushroom Agaricus bisporus is widely grown for food. The yeast Saccharomyces cerevisiae have been used for thousands of years to ferment beer and wine, and to leaven bread. Mould fungi including Penicillium are used to mature cheeses and other dairy products, as well as to make drugs such as antibiotics.

Effects

On domestic animals

Selection of animals for visible "desirable" traits may have undesired consequences. Captive and domesticated animals often have smaller size, piebald color, shorter faces with smaller and fewer teeth, diminished horns, weak muscle ridges, and less genetic variability. Poor joint definition, late fusion of the limb bone epiphyses with the diaphyses, hair changes, greater fat accumulation, smaller brains, simplified behavior patterns, extended immaturity, and more pathology are among the defects of domestic animals. All of these changes have been documented by archaeological evidence, and confirmed by animal breeders in the 20th century. In 2014, a study proposed the theory that under selection, docility in mammals and birds results partly from a slowed pace of neural crest development, that would in turn cause a reduced fear–startle response due to mild neurocristopathy that causes domestication syndrome. The theory was unable to explain curly tails nor domestication syndrome exhibited by plants.

A side effect of domestication has been zoonotic diseases. For example, cattle have given humanity various viral poxes, measles, and tuberculosis; pigs and ducks have given influenza; and horses have given the rhinoviruses. Many parasites have their origins in domestic animals. The advent of domestication resulted in denser human populations which provided ripe conditions for pathogens to reproduce, mutate, spread, and eventually find a new host in humans.

Paul Shepard writes "Man substitutes controlled breeding for natural selection; animals are selected for special traits like milk production or passivity, at the expense of overall fitness and nature-wide relationships...Though domestication broadens the diversity of forms – that is, increases visible polymorphism – it undermines the crisp demarcations that separate wild species and cripples our recognition of the species as a group. Knowing only domestic animals dulls our understanding of the way in which unity and discontinuity occur as patterns in nature, and substitutes an attention to individuals and breeds. The wide variety of size, color, shape, and form of domestic horses, for example, blurs the distinction among different species of Equus that once were constant and meaningful."

On society

Jared Diamond in his book Guns, Germs, and Steel describes the universal tendency for populations that have acquired agriculture and domestic animals to develop a large population and to expand into new territories. He recounts migrations of people armed with domestic crops overtaking, displacing or killing indigenous hunter-gatherers, whose lifestyle is coming to an end.

Some anarcho-primitivist authors describe domestication as the process by which previously nomadic human populations shifted towards a sedentary or settled existence through agriculture and animal husbandry. They claim that this kind of domestication demands a totalitarian relationship with both the land and the plants and animals being domesticated. They say that whereas, in a state of wildness, all life shares and competes for resources, domestication destroys this balance. Domesticated landscape (e.g. pastoral lands/agricultural fields and, to a lesser degree, horticulture and gardening) ends the open sharing of resources; where "this was everyone's", it is now "mine". Anarcho-primitivists state that this notion of ownership laid the foundation for social hierarchy as property and power emerged. It also involved the destruction, enslavement, or assimilation of other groups of early people who did not make such a transition.

Under the framework of Dialectical naturalism, Murray Bookchin has argued that the basic notion of domestication is incomplete: That, since the domestication of animals is a crucial development within human history, it can also be understood as the domestication of humanity itself in turn. Under this dialectical framework, domestication is always a 'two-way street' with both parties being unavoidably altered by their relationship with each other.

On diversity

Industrialized wheat harvest – North America today
 

In 2016, a study found that humans have had a major impact on global genetic diversity as well as extinction rates, including a contribution to megafaunal extinctions. Pristine landscapes no longer exist and have not existed for millennia, and humans have concentrated the planet's biomass into human-favored plants and animals. Domesticated ecosystems provide food, reduce predator and natural dangers, and promote commerce, but have also resulted in habitat loss and extinctions commencing in the Late Pleistocene. Ecologists and other researchers are advised to make better use of the archaeological and paleoecological data available for gaining an understanding the history of human impacts before proposing solutions.
