214-408: Nudity is the state of being in which a human is without clothing . While estimates vary, for the first 90,000 years of pre-history, anatomically modern humans were naked, having lost their body hair and living in hospitable climates. As humans became behaviorally modern , body adornments such as jewelry, tattoos, body paint and scarification became part of non-verbal communications, indicating
428-525: A mercantile society. In "conjectural histories" , authors such as Adam Ferguson (1723–1816), John Millar (1735–1801) and Adam Smith (1723–1790) argued that societies all pass through a series of four stages: hunting and gathering, pastoralism and nomadism, agriculture, and finally a stage of commerce . Philosophical concepts of progress , such as that of Hegel, developed as well during this period. In France , authors such as Claude Adrien Helvétius (1715–1771) and other philosophes were influenced by

As such, social interactions between humans have established a wide variety of values, social norms , languages , and traditions (collectively termed institutions ), each of which bolsters human society . Humans are also highly curious , with

This has allowed great technological advancements and complex tool development through complex reasoning and the transmission of knowledge to subsequent generations through language . Humans have had a dramatic effect on the environment . They are apex predators , being rarely preyed upon by other species. Human population growth , industrialization, land development, overconsumption and combustion of fossil fuels have led to environmental destruction and pollution that significantly contributes to
1070-470: A "revolution in ideas about the antiquity of the human species" took place "which paralleled, but was to some extent independent of, the Darwinian revolution in biology." Especially in geology, archaeology, and anthropology, scholars began to compare "primitive" cultures to past societies and "saw their level of technology as parallel with that of Stone Age cultures, and thus used these peoples as models for
1284-437: A 1980 law requiring the admission of women. For younger boys, lack of modesty might include public behavior as in 1909 when The New York Times reported that at an elementary school public swimming competition the youngest boys competed in the nude. Hygiene was given as the reason for official guidelines requiring nudity in indoor pools used only by men. Swimmers were also required to take nude showers with soap prior to entering
1498-513: A basin attached to every cathedral. Both men and women were baptized naked, deaconesses performing the rite for women to maintain modesty. Until the fifth century CE, pagan nudity was associated with sex, Christian nudity with grace . Jesus was originally depicted nude as would have been the case in Roman crucifixions, but the Christian adoption of the pagan association of the body with sex prompted
1712-608: A belief that the changes in Europe brought by the Industrial Revolution and capitalism were improvements. Industrialisation, combined with the intense political change brought about by the French Revolution of 1789 and the U.S. Constitution , which paved the way for the dominance of democracy , forced European thinkers to reconsider some of their assumptions about how society was organised. Eventually, in
1926-419: A belt with a piece of string attached holding their foreskin shut over their glans penis . There was no shame or modesty attached to women's breasts, and therefore no garments devoted to concealing them; however, women did cover their pubic area in the presence of men, as exposing it was a cultural expression of anger and contempt. Pre-pubescent children wore no clothes at all. European colonists cited nudity as

These 19th-century ethnologists used these principles primarily to explain differences in religious beliefs and kinship terminologies among various societies. Lester Frank Ward (1841–1913), sometimes referred to as the "father" of American sociology, rejected many of Spencer's theories regarding
2354-412: A conjectural stage-model of human sociocultural evolution: first, humans lived solitarily and only grouped when mating or raising children. Later, men and women lived together and shared childcare, thus building families, followed by tribes as the result of inter-family interactions, which lived in "the happiest and the most lasting epoch" of human history, before the corruption of civil society degenerated

Like many other conditions, body weight and body type are influenced by both genetic susceptibility and environment and varies greatly among individuals. Humans have a far faster and more accurate throw than other animals. Humans are also among

Since then, a number of civilizations have risen and fallen, while a number of sociocultural and technological developments have resulted in significant changes to
3210-432: A fixed system of growth of humanity as a whole and examining the modes and mechanisms of this growth. Theirs was often a concern with culture in general, not with individual cultures. Their analysis of cross-cultural data was based on three assumptions: Theorists usually measured progression (that is, the difference between one stage and the next) in terms of increasing social complexity (including class differentiation and
3424-713: A form of protest, and those with power may impose nakedness on others as a form of punishment. While the majority of contemporary societies require clothing in public, some recognize non-sexual nudity as being appropriate for some recreational, social or celebratory activities, and appreciate nudity in the arts as representing positive values. A minority within many countries assert the benefits of social nudity , while other groups continue to disapprove of nudity not only in public but also in private based upon religious beliefs. Norms are codified to varying degrees by laws defining proper dress and indecent exposure . In general English usage, nude and naked are often synonyms for
3638-463: A great capacity for altering their habitats by means of technology, irrigation , urban planning , construction, deforestation and desertification . Human settlements continue to be vulnerable to natural disasters , especially those placed in hazardous locations and with low quality of construction. Grouping and deliberate habitat alteration is often done with the goals of providing protection, accumulating comforts or material wealth, expanding
3852-534: A great influence not only on future evolutionary approaches in the social sciences and humanities, but also shaped public, scholarly, and scientific discourse surrounding the rising individualism and population thinking. Sociocultural evolutionism attempted to formalise social thinking along scientific lines, with the added influence from the biological theory of evolution . If organisms could develop over time according to discernible, deterministic laws, then it seemed reasonable that societies could as well. Human society

Through the mechanism of imitation, cultures as well as individuals could be subject to natural selection. While these theories involved evolution applied to social questions, except for Darwin's group selection

Females are capable of pregnancy , usually between puberty, at around 12 years old, and menopause , around the age of 50. As omnivorous creatures, they are capable of consuming a wide variety of plant and animal material, and have used fire and other forms of heat to prepare and cook food since the time of Homo erectus . Humans can survive for up to eight weeks without food and several days without water . Humans are generally diurnal , sleeping on average seven to nine hours per day. Childbirth

To be naked is more straightforward, not being properly dressed, or if stark naked , entirely without clothes. Nudity has more cultural connotations, and particularly in the fine arts, positive associations with the beauty of the human body. Further synonyms and euphemisms for nudity abound, including " birthday suit ", " in

The lineage of apes that eventually gave rise to humans first split from gibbons (family Hylobatidae) and orangutans (genus Pongo ), then gorillas (genus Gorilla ), and finally, chimpanzees and bonobos (genus Pan ). The last split, between the human and chimpanzee–bonobo lineages, took place around 8–4 million years ago, in
4922-417: A legal right in public and the workplace. Where public breastfeeding is unregulated or legal, mothers may be reluctant to do so because other people may object. The issue of breastfeeding is part of the sexualization of the breast in many cultures, and the perception of threat in what others perceive as non-sexual. Pope Francis came out in support of public breastfeeding at church services soon after assuming
5136-638: A loincloth for men and a skirt for women. The Tokugawa period in Japan (1603–1868) was defined by the social dominance of hereditary classes, with clothing a regulated marker of status and little nudity among the upper classes. However, working populations in both rural and urban areas often dressed only in fundoshi (similar to a loincloth ), including women in hot weather and while nursing. Lacking baths in their homes, everyone frequented public bathhouses where they were unclothed together. This communal nudity might extend to other activities in rural villages. With

Apart from bipedalism and brain size, humans differ from chimpanzees mostly in smelling , hearing and digesting proteins . While humans have a density of hair follicles comparable to other apes, it is predominantly vellus hair , most of which is so short and wispy as to be practically invisible. Humans have about 2 million sweat glands spread over their entire bodies, many more than chimpanzees, whose sweat glands are scarce and are mainly located on
5564-504: A much clearer picture of life at the time. Between the 8th and 6th century BCE, Europe entered the classical antiquity age, a period when ancient Greece and ancient Rome flourished. Around this time other civilizations also came to prominence. The Maya civilization started to build cities and create complex calendars . In Africa, the Kingdom of Aksum overtook the declining Kingdom of Kush and facilitated trade between India and
5778-548: A natural curiosity about their own bodies and the bodies of others. The report recommended that parents learn what is normal in regard to nudity and sexuality at each stage of a child's development and refrain from overreacting to their children's nudity-related behaviors unless there are signs of a problem (e.g. anxiety, aggression, or sexual interactions between children not of the same age or stage of development). Problematic childhood behavior often takes place in daycare, rather than home environments. The general advice for caregivers
5992-446: A person's membership in their society, thus nakedness meant being at the bottom of the social scale, lacking in dignity and status. In each culture, ornamentation represented the wearer's place in society; position of authority, economic class, gender role, and marital status. From the beginning of civilization, there was ambiguity regarding everyday nakedness and the nudity in depictions of deities and heroes indicating positive meanings of
6206-495: A person's social and individual characteristics. Indigenous peoples in warm climates used clothing for decorative, symbolic or ceremonial purposes but were often nude, having neither the need to protect the body from the elements nor any conception of nakedness being shameful. In many societies, both ancient and contemporary, children might be naked until the beginning of puberty. Women may not cover their breasts if they were associated with nursing babies more than with sexuality. In

Thorstein Veblen, around the same time, came to a similar insight: that humans evolve to their social environment, but their social environment in turn also evolves. Veblen's mechanism for human progress
6634-465: A protest by mothers. However, only the middle school required suits, the elementary schools in the same district continued to allow girls to swim nude. The public health recommendation of male nudity continued officially until 1962 but was observed into the 1970s by the YMCA and schools with gender segregated classes. The era of male nude swimming in indoor pools declined steadily as mixed-gender usage became

This is not to suggest that stagism was useless or entirely motivated by colonialism and racism. Stagist theories were first proposed in contexts where competing epistemologies were largely static views of the world. Hence "progress" had in some sense to be invented, conceptually:

Tönnies' work became the foundation of neoevolutionism. Although Max Weber is not usually counted as a sociocultural evolutionist, his theory of tripartite classification of authority can be viewed as an evolutionary theory as well. Weber distinguishes three ideal types of political leadership , domination and authority : Weber also notes that legal domination

In Etruscan and early Roman athletics, in which masculinity involved prudishness and paranoia about effeminacy , the Greek traditions were not maintained because public nudity became associated with homoeroticism . In the Roman Empire (27 BCE – 476 CE), the status of

Another attempt, on a less systematic scale, originated from the 1970s with the world-systems approach of Immanuel Wallerstein (1930-2019) and his followers. More recent approaches focus on changes specific to individual societies and reject the idea that cultures differ primarily according to how far each one has moved along some presumed linear scale of social progress . Most modern archaeologists and cultural anthropologists work within

On the islands of Yap State , dances by women in traditional dress that does not cover the breasts are now included in the Catholic celebration of Christmas and Easter.

The Neolithic Revolution , which began in Southwest Asia around 13,000 years ago (and separately in
8346-515: A simple linear or branched progression but involved interbreeding between related species . Genomic research has shown that hybridization between substantially diverged lineages was common in human evolution. DNA evidence suggests that several genes of Neanderthal origin are present among all non sub-Saharan-African populations, and Neanderthals and other hominins, such as Denisovans , may have contributed up to 6% of their genome to present-day non sub-Saharan-African humans.

Embryonic development in the human covers the first eight weeks of development; at the beginning of the ninth week the embryo is termed a fetus . Humans are able to induce early labor or perform a caesarean section if the child needs to be born earlier for medical reasons. In developed countries, infants are typically 3–4 kg (7–9 lb) in weight and 47–53 cm (19–21 in) in height at birth. However, low birth weight

Like other mammals, humans have an XY sex-determination system , so that females have the sex chromosomes XX and males have XY. Genes and environment influence human biological variation in visible characteristics, physiology, disease susceptibility and mental abilities.

Thus Tönnies can be said to describe part of the process known today as globalization . Tönnies was also one of the first sociologists to claim that the evolution of society is not necessarily going in the right direction, that social progress is not perfect, and it can even be called
10486-558: Is accepted as natural. In contemporary rural villages, both boys and girls are allowed to play totally nude, and women bare their breasts in the belief that the meaning of naked bodies is not limited to sexuality. Full or partial nudity is observed among some Burkinabese and Nilo-Saharan (e.g. Nuba and Surma people )—during particular occasions; for example, stick-fighting tournaments in Ethiopia. In Lagos, Nigeria , some parents continue to allow children to be naked until puberty. There

People in Western cultures may practice social nudity within the confines of semi-private facilities such as naturist resorts , while other seek more open acceptance of nudity in everyday life and in public spaces designated as clothing-optional. In the Islamic societies of Africa nudity is forbidden, while in sub-Saharan countries that never abandoned, or are reasserting, pre-colonial norms partial or complete nudity

He believed that societies were at different stages of cultural development and that the purpose of anthropology was to reconstruct the evolution of culture, from primitive beginnings to the modern state.

Other examples of ethnic tourism reflect the visitor's desire to experience what they imagine being an exotic culture, which includes nudity. In Asian countries, rather than always being immoral or shameful, not being properly dressed
11556-736: Is associated with sin, criminality, and punishment. The strong connection of nudity to sex produces shame when naked in contexts where sexuality is deemed inappropriate. The connection of nakedness with the corruptibility of flesh and death may have biblical origins, but gained real world associations during epidemics in the Middle Ages. Confronted with this ambiguity, some individuals seek to resolve it by working toward greater acceptance of nudity for themselves and others. Although psychologist Keon West found positive effects from short-term participation in social nudity, such as an improved body image, sociologist Barbara Górnicka found that lasting change

Nudity also represents freedom: the liberation of the body is associated with sexual liberation, although many naturists tend to downplay this connection. In some forms of group psychotherapy , nudity has been used to promote open interaction and communication. Religious persons who reject

Compared with other species, human childbirth is dangerous, with a much higher risk of complications and death.

Much of what is known about the early history of clothing is from depictions of the higher classes, there being few surviving artifacts. Everyday behaviors are rarely represented in historical records. Clothing and adornment became part of the symbolic communication that marked

The meaning of the creation myth is inconsistent with a philosophical analysis of shame as an emotion of reflective self-assessment which is understood as a response to being seen by others, a social context that did not exist.

The early 20th-century inaugurated a period of systematic critical examination, and rejection of the sweeping generalisations of the unilineal theories of sociocultural evolution.

It has been proposed that menopause increases a woman's overall reproductive success by allowing her to invest more time and resources in her existing offspring, and in turn their children (the grandmother hypothesis ), rather than by continuing to bear children into old age.

A tenuous balance of power among European nations collapsed in 1914 with the outbreak of the First World War , one of the deadliest conflicts in history. In the 1930s, a worldwide economic crisis led to the rise of authoritarian regimes and a Second World War , involving almost all of the world's countries . The war's destruction led to
16906-580: The Caral–Supe civilization is the oldest complex civilization in the Americas. Astronomy and mathematics were also developed and the Great Pyramid of Giza was built. There is evidence of a severe drought lasting about a hundred years that may have caused the decline of these civilizations, with new ones appearing in the aftermath. Babylonians came to dominate Mesopotamia while others, such as
17120-511: The Church would provide centralized authority and education. In the Middle East, Islam became the prominent religion and expanded into North Africa. It led to an Islamic Golden Age , inspiring achievements in architecture , the revival of old advances in science and technology, and the formation of a distinct way of life. The Christian and Islamic worlds would eventually clash, with
17334-474: The Homo genus. The name " Homo sapiens " means 'wise man' or 'knowledgeable man'. There is disagreement if certain extinct members of the genus, namely Neanderthals , should be included as a separate species of humans or as a subspecies of H. sapiens . Human is a loanword of Middle English from Old French humain , ultimately from Latin hūmānus , the adjectival form of homō ('man' – in
17548-579: The Kingdom of England , the Kingdom of France and the Holy Roman Empire declaring a series of holy wars to regain control of the Holy Land from Muslims . In the Americas, between 200 and 900 CE Mesoamerica was in its Classic Period , while further north, complex Mississippian societies would arise starting around 800 CE. The Mongol Empire would conquer much of Eurasia in the 13th and 14th centuries. Over this same time period,
17762-748: The Mali Empire in Africa grew to be the largest empire on the continent, stretching from Senegambia to Ivory Coast . Oceania would see the rise of the Tuʻi Tonga Empire which expanded across many islands in the South Pacific. By the late 15th century, the Aztecs and Inca had become the dominant power in Mesoamerica and the Andes , respectively. The early modern period in Europe and
17976-618: The New Kingdom of Egypt (1550–1069 BCE), that functionaries in the households of the wealthy began wearing refined dress, and upper-class women wore elaborate dresses and ornamentation which covered their breasts. These later styles are often shown in film and TV as representing Ancient Egypt in all periods. Male nudity was celebrated in ancient Greece to a greater degree than any culture before or since. The status of freedom, maleness, privilege, and physical virtues were asserted by discarding everyday clothing for athletic nudity. Nudity became
18190-587: The Old World over the following millennia. It also occurred independently in Mesoamerica (about 6,000 years ago), China, Papua New Guinea , and the Sahel and West Savanna regions of Africa. Access to food surplus led to the formation of permanent human settlements , the domestication of animals and the use of metal tools for the first time in history. Agriculture and sedentary lifestyle led to
18404-652: The Poverty Point culture , Minoans and the Shang dynasty , rose to prominence in new areas. The Late Bronze Age collapse around 1200 BCE resulted in the disappearance of a number of civilizations and the beginning of the Greek Dark Ages . During this period iron started replacing bronze, leading to the Iron Age . In the 5th century BCE, history started being recorded as a discipline , which provided
18618-483: The Scottish Enlightenment of the 18th century proved key in the development of the idea of sociocultural evolution. In relation to Scotland's union with England in 1707 , several Scottish thinkers pondered the relationship between progress and the affluence brought about by increased trade with England. They understood the changes Scotland was undergoing as involving transition from an agricultural to
18832-652: The Zoonomia , to illustrate cultural development as well. Erasmus Darwin therefore flits with abandon through his chronology: Priestman notes that it jumps from the emergence of life onto land, the development of opposable thumbs, and the origin of sexual reproduction directly to modern historical events. Another more complex theorist was Richard Payne Knight (1751-1824), an influential amateur archeologist and universal theologian. Knight's The Progress of Civil Society: A Didactic Poem in Six Books (1796) fits precisely into
19046-795: The colonization of the Americas and the Columbian Exchange . This expansion led to the Atlantic slave trade and the genocide of Native American peoples . This period also marked the Scientific Revolution , with great advances in mathematics , mechanics , astronomy and physiology . The late modern period (1800–present) saw the Technological and Industrial Revolution bring such discoveries as imaging technology , major innovations in transport and energy development . Influenced by Enlightenment ideals,
19260-617: The leaders of anthropology's rejection of classical social evolutionism. However, the school of Boas ignore some of the complexity in evolutionary theories that emerged outside Herbert Spencer's influence. Charles Darwin's On the Origin of Species gave a mechanistic account of the origins and development of animals, quite apart from Spencer's theories that emphasized the inevitable human development through stages. Consequently, many scholars developed more sophisticated understandings of how cultures evolve, relying on deep cultural analogies, than
19474-621: The "laws" of history. While sociocultural evolutionists agree that an evolution-like process leads to social progress, classical social evolutionists have developed many different theories, known as theories of unilineal evolution. Sociocultural evolutionism became the prevailing theory of early sociocultural anthropology and social commentary , and is associated with scholars like Auguste Comte , Edward Burnett Tylor , Lewis Henry Morgan , Benjamin Kidd , L. T. Hobhouse and Herbert Spencer . Such stage models and ideas of linear models of progress had
19688-420: The "military" and "industrial" societies. The earlier (and more primitive) military society has the goal of conquest and defense, is centralised , economically self-sufficient , collectivistic , puts the good of a group over the good of an individual, uses compulsion, force and repression, and rewards loyalty, obedience and discipline. The industrial society, in contrast, has a goal of production and trade ,
19902-408: The 'laws of creation', though he also supposed that the whole development of species was in some way preordained: it was just that the preordination of the creator acted through establishing those laws. This, as discussed above, is similar to Spencer's later concept of development. Thus Chambers believed in a sophisticated theory of progress driven by a developmental analogy. In the mid-19th century,
20116-686: The 1870s, particularly in the United States . Authors such as Edward L. Youmans , William Graham Sumner , John Fiske , John W. Burgess , Lester Frank Ward , Lewis H. Morgan (1818–1881) and other thinkers of the gilded age all developed theories of social evolutionism as a result of their exposure to Spencer as well as to Darwin. In his 1877 classic Ancient Societies , Lewis H. Morgan, an anthropologist whose ideas have had much impact on sociology, differentiated between three eras: savagery , barbarism and civilization , which are divided by technological inventions, like fire, bow , pottery in
20330-439: The 19th century three major classical theories of social and historical change emerged: These theories had a common factor: they all agreed that the history of humanity is pursuing a certain fixed path, most likely that of social progress. Thus, each past event is not only chronologically, but causally tied to present and future events. The theories postulated that by recreating the sequence of those events, sociology could discover
20544-518: The Americas and Europe experienced a period of political revolutions known as the Age of Revolution . The Napoleonic Wars raged through Europe in the early 1800s, Spain lost most of its colonies in the New World , while Europeans continued expansion into Africa – where European control went from 10% to almost 90% in less than 50 years – and Oceania. In the 19th century,
20758-748: The Body" given in 1979, Pope John Paul II said that the innocent nudity of being before the fall is regained only between loving spouses. In daily life, Christianity requires clothing in public, but with great variation between and within societies as to the meaning of "public" and how much of the body is covered. Finnish Lutherans practice mixed nudity in private saunas used by families and close-knit groups. While maintaining communal nudity, men and women are now often separated in public or community settings. Certain sects of Christianity through history have included nudity into worship practices, but these have been deemed heretical . There have been Christian naturists in
20972-532: The Family, Private Property and the State on them. For Engels and other Marxists this theory was important, as it supported their conviction that materialistic factors—economic and technological—are decisive in shaping the fate of humanity. Edward Burnett Tylor (1832–1917), a pioneer of anthropology, focused on the evolution of culture worldwide, noting that culture is an important part of every society and that it
21186-432: The Greek classical and later Abrahamic traditions has resulted in Western ambivalence, with nudity acquiring both positive and negative meanings in individual psychology, in social life, and in depictions such as art. The conservative versions of these religions continue to prohibit public and sometimes also private nudity. While public modesty prevails in more recent times, organized groups of nudists or naturists emerged with
21400-876: The Mediterranean. In West Asia, the Achaemenid Empire 's system of centralized governance became the precursor to many later empires, while the Gupta Empire in India and the Han dynasty in China have been described as golden ages in their respective regions. Following the fall of the Western Roman Empire in 476, Europe entered the Middle Ages . During this period, Christianity and
21614-832: The Near East ( c. 1450 –1800) began with the final defeat of the Byzantine Empire , and the rise of the Ottoman Empire . Meanwhile, Japan entered the Edo period , the Qing dynasty rose in China and the Mughal Empire ruled much of India. Europe underwent the Renaissance , starting in the 15th century, and the Age of Discovery began with the exploring and colonizing of new regions. This included
21828-578: The Netherlands went through the same period of feminist activism in the 1960s–70s, but Dutch men were generally more open to the idea of gender equality, there being a prior history of regarding sexuality as healthy and normal, including nudity not always being sexual. A report issued in 2009 on child sexual development in the United States by the National Child Traumatic Stress Network asserted that children have
22042-576: The Papacy. Historically, men and boys bathed and swam nude in secluded rivers and lakes. In England when sea bathing became popular in the 18th century, beaches were initially male only, but with the easier access of the 19th century due to rail transportation, the mixing of genders became a problem for authorities. The addition of " bathing machines " at seaside resorts was not successful in maintaining standards of decency, men often continuing to be nude while women wore bathing costumes. However, public concern
22256-590: The Scottish tradition. Later thinkers such as Comte de Saint-Simon (1760–1825) developed these ideas. Auguste Comte (1798–1857) in particular presented a coherent view of social progress and a new discipline to study it: sociology. These developments took place in a context of wider processes. The first process was colonialism. Although imperial powers settled most differences of opinion with their colonial subjects through force, increased awareness of non-Western peoples raised new questions for European scholars about
22470-501: The United States promotes equal rights for women to be naked above the waist in public on the same basis that would apply to men in the same circumstances. Advocates of topfreedom view its illegality as the institutionalization of negative cultural values that affect women's body image. The legal justifications for topfreedom include equal protection , the right to privacy , and freedom of expression . The law in New York State
22684-541: The United States since the 1920s, but as a social and recreational practice rather than part of an organized religion. Islamic countries are guided by rules of modesty that forbid nudity, with variations between five schools of Islamic law. The most conservative is the Hanbali School in Saudi Arabia and Qatar, where the niqab , the garment covering the whole female body and the face with a narrow opening for
22898-555: The Western civilization), appeared the result of steady progress from a state of barbarism, and such a notion was common to many thinkers of the Enlightenment, including Voltaire (1694–1778). The second process was the Industrial Revolution and the rise of capitalism , which together allowed and promoted continual revolutions in the means of production . Emerging theories of sociocultural evolution reflected
23112-434: The altogether " and " in the buff ". Partial nudity may be defined as not covering the genitals or other parts of the body deemed sexual, such as the buttocks or female breasts . Two human evolutionary processes are significant regarding nudity; first the biological evolution of early hominids from being covered in fur to being effectively hairless, followed by the sociocultural evolution of adornments and clothing. In
23326-443: The ancestral form". Most of the 19th-century and some 20th-century approaches to socioculture aimed to provide models for the evolution of humankind as a whole, arguing that different societies have reached different stages of social development . The most comprehensive attempt to develop a general theory of social evolution centering on the development of sociocultural systems, the work of Talcott Parsons (1902–1979), operated on
23540-712: The ancient civilizations of the Mediterranean, from Mesopotamia to the Roman Empire, proper attire was required to maintain social standing. The lower classes might possess a single piece of cloth that was wrapped or tied to cover the lower body; the lowest classes including slaves might be naked. However, through much of Western history until the modern era , people of any status were also unclothed by necessity or convenience when engaged in labor and athletics; or when bathing or swimming. Such functional nudity occurred in groups that were usually but not always segregated by sex . Although improper dress might be socially embarrassing,
23754-408: The association of nudity with sin regarding sexuality began with Judeo-Christian societies, spreading through Europe in the post-classical period. Traditional clothing in temperate regions worldwide also reflect concerns for maintaining social status and order, as well as by necessity due to the colder climate. However, societies such as Japan and Finland maintain traditions of communal nudity based upon
23968-478: The available food, improving aesthetics , increasing knowledge or enhancing the exchange of resources. Humans are one of the most adaptable species, despite having a low or narrow tolerance for many of the earth's extreme environments. Currently the species is present in all eight biogeographical realms , although their presence in the Antarctic realm is very limited to research stations and annually there
24182-561: The best long-distance runners in the animal kingdom, but slower over short distances. Humans' thinner body hair and more productive sweat glands help avoid heat exhaustion while running for long distances. Compared to other apes, the human heart produces greater stroke volume and cardiac output and the aorta is proportionately larger. Like most animals, humans are a diploid and eukaryotic species. Each somatic cell has two sets of 23 chromosomes , each set received from one parent; gametes have only one set of chromosomes, which
24396-402: The body, such garments might be removed in public for practical or ceremonial purposes. Children until puberty and sometimes women until marriage might be naked. All humans lived in hunter-gatherer societies until 20,000 years ago, and they were naked. In the tropical regions of Africa, Australia, the Americas and Southeast Asia, this way of life continued until a few hundred years ago. Perhaps
24610-605: The changing environment through the formation of new institutions." Thus, Veblen represented an extension of Ritchie's theories, where evolution operates at multiple levels, to a sophisticated appreciation of how each level interacts with the other. This complexity notwithstanding, Boas and Benedict used sophisticated ethnography and more rigorous empirical methods to argue that Spencer, Tylor, and Morgan's theories were speculative and systematically misrepresented ethnographic data. Theories regarding "stages" of evolution were especially criticised as illusions. Additionally, they rejected
24824-433: The clothing of Christ. Some clerics went further, to hatred and fear of the body, insisting that monks sleep fully dressed. Christian theology rarely addresses nudity, but rather proper dress and modesty. Western cultures adopted Greek heritage only with regard to art, the ideal nude. Real naked people remained shameful, and become human only when they cover their nakedness. In one of a series of lectures entitled "Theology of
25038-603: The collapse of most global empires, leading to widespread decolonization. Following the conclusion of the Second World War in 1945, the United States and the USSR emerged as the remaining global superpowers . This led to a Cold War that saw a struggle for global influence, including a nuclear arms race and a space race , ending in the collapse of the Soviet Union. The current Information Age , spurred by
25252-787: The combined eastern and western Roman Empire in the 4th century AD. Bubonic plagues , first recorded in the 6th century AD, reduced the population by 50%, with the Black Death killing 75–200 million people in Eurasia and North Africa alone. Human population is believed to have reached one billion in 1800. It has since then increased exponentially, reaching two billion in 1930 and three billion in 1960, four in 1975, five in 1987 and six billion in 1999. It passed seven billion in 2011 and passed eight billion in November 2022. It took over two million years of human prehistory and history for
25466-478: The continent, gradually replacing or interbreeding with local populations of archaic humans. Humans began exhibiting behavioral modernity about 160,000–70,000 years ago, and possibly earlier. This development was likely selected amidst natural climate change in Middle to Late Pleistocene Africa. The "out of Africa" migration took place in at least two waves, the first around 130,000 to 100,000 years ago,
25680-402: The course of human history . Georg Wilhelm Friedrich Hegel (1770–1831), for example, saw social development as an inevitable process. It was assumed that societies start out primitive, perhaps in a state of nature , and could progress toward something resembling industrial Europe. While earlier authors such as Michel de Montaigne (1533–1592) had discussed how societies change through time,
25894-423: The desire to understand and influence phenomena having motivated humanity's development of science , technology , philosophy , mythology , religion , and other frameworks of knowledge ; humans also study themselves through such domains as anthropology , social science , history , psychology , and medicine . There are estimated to be more than eight billion living humans . Although some scientists equate
26108-520: The development of laws, the presence or absence of civil liberty, differences in morality, and the whole development of different cultures to the climate of the respective people, concluding that the environment determines whether and how a people farms the land, which determines the way their society is built and their culture is constituted, or, in Montesquieu's words, the "general spirit of a nation". Also Jean-Jacques Rousseau (1712–1778) presents
26322-516: The development of the Internet and Artificial Intelligence systems, sees the world becoming increasingly globalized and interconnected. Early human settlements were dependent on proximity to water and – depending on the lifestyle – other natural resources used for subsistence , such as populations of animal prey for hunting and arable land for growing crops and grazing livestock. Modern humans, however, have
26536-462: The direct intervention of some beneficent deity. Moreover, he accepted that these conditions are "far less specific, far more modifiable, far more dependent on conditions that are variable": in short, that they are a messy biological process. Though Spencer's theories transcended the label of 'stagism' and appreciate biological complexity, they still accepted a strongly fixed direction and morality to natural development. For Spencer, interference with
26750-427: The distinction between "primitive" and "civilized" (or "modern"), pointing out that so-called primitive contemporary societies have just as much history, and were just as evolved, as so-called civilized societies. They therefore argued that any attempt to use this theory to reconstruct the histories of non-literate (i.e. leaving no historical documents) peoples is entirely speculative and unscientific. They observed that
26964-423: The dramatic enlargement of the brain, the most temperature-sensitive human organ. Some of the technology for what is now called clothing may have originated to make other types of adornment, including jewelry , body paint , tattoos , and other body modifications , "dressing" the naked body without concealing it. According to Mark Leary and Nicole Buttermore, body adornment is one of the changes that occurred in
27178-640: The early 20th century, there has been continuous human presence in Antarctica through research stations and, since 2000, in space through habitation on the International Space Station . All modern humans are classified into the species Homo sapiens , coined by Carl Linnaeus in his 1735 work Systema Naturae . The generic name " Homo " is a learned 18th-century derivation from Latin homō , which refers to humans of either sex. The word human can refer to all members of
27392-533: The early stages of human evolution." A developmental model of the evolution of the mind, culture, and society was the result, paralleling the evolution of the human species: "Modern savages [sic] became, in effect, living fossils left behind by the march of progress, relics of the Paleolithic still lingering on into the present." Classical social evolutionism is most closely associated with the 19th-century writings of Auguste Comte and of Herbert Spencer (coiner of
27606-685: The emergence of early civilizations . An urban revolution took place in the 4th millennium BCE with the development of city-states , particularly Sumerian cities located in Mesopotamia . It was in these cities that the earliest known form of writing, cuneiform script , appeared around 3000 BCE. Other major civilizations to develop around this time were Ancient Egypt and the Indus Valley Civilisation . They eventually traded with each other and invented technology such as wheels, plows and sails. Emerging by 3000 BCE,
27820-530: The entire body, similar to Western dress. In stories written in China as early as the fourth century BCE, nudity is presented as an affront to human dignity , reflecting the belief that "humanness" in Chinese society is not innate, but is earned by correct behavior. However, nakedness could also be used by an individual to express contempt for others in their presence. In other stories, the nudity of women, emanating
28034-416: The evolution of societies. Ward, who was also a botanist and a paleontologist, believed that the law of evolution functioned much differently in human societies than it did in the plant and animal kingdoms, and theorized that the "law of nature" had been superseded by the "law of the mind". He stressed that humans, driven by emotions, create goals for themselves and strive to realize them (most effectively with
28248-490: The evolutionary processes have four stages: Ward regarded modern societies as superior to "primitive" societies (one need only look to the impact of medical science on health and lifespan ) and shared theories of white supremacy . Though he supported the Out-of-Africa theory of human evolution, he did not believe that all races and social classes were equal in talent. When a Negro rapes a white woman, Ward declared, he
28462-412: The explanation of natural phenomena from them; until the final positive stage in which all abstract and obscure forces are discarded, and natural phenomena are explained by their constant relationship. This progress is forced through the development of human mind, and through increasing application of thought, reasoning and logic to the understanding of the world. Comte saw the science-valuing society as
28676-457: The extent to which they describe specific mechanisms of variation and change. While the history of evolutionary thinking with regard to humans can be traced back at least to Aristotle and other Greek philosophers, early sociocultural-evolution theories – the ideas of Auguste Comte (1798–1857), Herbert Spencer (1820–1903) and Lewis Henry Morgan (1818–1881) – developed simultaneously with, but independently of,
28890-514: The eyes, is widespread. Hands are also hidden within sleeves as much as possible. The burqa , limited mainly to Afghanistan, also has a mesh screen which covers the eye opening. Different rules apply to men, women, and children; and depend upon the gender and family relationship of others present. In Western cultures, shame can result from not living up to the ideals of society with regard to physical appearance. Historically, such shame has affected women more than men. With regard to their naked bodies,
29104-535: The facts of social evolution on the one hand, and of zoological evolution as expounded by Mr Darwin on the other'. Charles Sanders Peirce (1898) even proposed that the current laws of nature we have exist because they have evolved over time. Darwin himself, in Chapter 5 of the Descent of Man, proposed that human moral sentiments were subject to group selection: "A tribe including many members who, from possessing in
29318-446: The fall". According to German philosopher Thorsten Botz-Bornstein , interpretations of Genesis have placed responsibility for the fall of man and original sin on Eve, and, therefore, all women. As a result, the nudity of women is deemed more shameful personally and corrupting to society than the nakedness of men. The meaning of nudity for early Christians was the baptism , which was originally by full immersion and without clothes in
29532-406: The first half of the 20th century, and marked a retreat from high-level generalization and from "systems building". Later critics observed that the assumption of firmly bounded societies was proposed precisely at the time when European powers were colonising non-Western societies, and was thus self-serving. Many anthropologists and social theorists now consider unilineal cultural and social evolution
29746-680: The framework of multilineal evolution. Other contemporary approaches to social change include neoevolutionism , sociobiology , dual inheritance theory , modernisation theory and postindustrial theory. In his seminal 1976 book The Selfish Gene , Richard Dawkins wrote that "there are some examples of cultural evolution in birds and monkeys, but ... it is our own species that really shows what cultural evolution can do". Enlightenment and later thinkers often speculated that societies progressed through stages: in other words, they saw history as stadial . While expecting humankind to show increasing development, theorists looked for what determined
29960-518: The frameworks of neoevolutionism , sociobiology , and modernization theory . Anthropologists and sociologists often assume that human beings have natural social tendencies but that particular human social behaviours have non- genetic causes and dynamics (i.e. people learn them in a social environment and through social interaction ). Societies exist in complex social environments (for example: with differing natural resources and constraints) and adapt themselves to these environments. It
30174-566: The genomes of 1,184 individuals from 11 populations and identified 1.6 million single nucleotide polymorphisms . African populations harbor the highest number of private genetic variants. While many of the common variants found in populations outside of Africa are also found on the African continent, there are still large numbers that are private to these regions, especially Oceania and the Americas . By 2010 estimates, humans have approximately 22,000 genes. By comparing mitochondrial DNA , which
30388-595: The global average life expectancy at birth of a girl is estimated to be 74.9 years compared to 70.4 for a boy. There are significant geographical variations in human life expectancy, mostly correlated with economic development – for example, life expectancy at birth in Hong Kong is 87.6 years for girls and 81.8 for boys, while in the Central African Republic , it is 55.0 years for girls and 50.6 for boys. The developed world
30602-415: The highest, most developed type of human organization. Herbert Spencer, who argued against government intervention as he believed that society should evolve toward more individual freedom, followed Lamarck in his evolutionary thinking, in that he believed that humans do over time adapt to their surroundings. He differentiated between two phases of development as regards societies' internal regulation:
30816-443: The human lifestyle. Genes and the environment influence human biological variation in visible characteristics, physiology , disease susceptibility, mental abilities, body size, and life span. Though humans vary in many traits, humans are among the least genetically diverse species. Any two humans are at least 99.5% genetically similar. Humans are sexually dimorphic : generally, males have greater body strength and females have
31030-555: The human population to reach one billion and only 207 years more to grow to 7 billion. The combined biomass of the carbon of all the humans on Earth in 2018 was estimated at 60 million tons, about 10 times larger than that of all non-domesticated mammals. In 2018, 4.2 billion humans (55%) lived in urban areas, up from 751 million in 1950. The most urbanized regions are Northern America (82%), Latin America (81%), Europe (74%) and Oceania (68%), with Africa and Asia having nearly 90% of
31244-517: The human population was reduced to a small number of breeding pairs. The forces of natural selection have continued to operate on human populations, with evidence that certain regions of the genome display directional selection in the past 15,000 years. The human genome was first sequenced in 2001 and by 2020 hundreds of thousands of genomes had been sequenced. In 2012 the International HapMap Project had compared
31458-399: The idea of European superiority used paternalistically to justify those projects. The influential German zoologist Ernst Haeckel even wrote that 'natural men are closer to the higher vertebrates than highly civilized Europeans', including not just a racial hierarchy but a civilizational one. Likewise, Spencer's evolutionary argument advanced a theory of statehood: "until spontaneously fulfilled
31672-458: The idea that human society would move through stages was a triumphant invention. Moreover, stages were not always static entities. In Buffon's theories, for example, it was possible to regress between stages, and physiological changes were species' reversibly adapting to their environment rather than irreversibly transforming. In addition to progressivism, economic analyses influenced classical social evolutionism. Adam Smith (1723–1790), who held
31886-478: The ideas of biological evolution as an attractive explanation for many questions about the development of society. Both Spencer and Comte view society as a kind of organism subject to the process of growth—from simplicity to complexity, from chaos to order, from generalisation to specialisation, from flexibility to organisation. They agree that the process of societal growth can be divided into certain stages, have their beginning and eventual end, and that this growth
32100-504: The interconnectedness of all forms of life. His works, which are enormously wide-ranging, also advance a theory of cultural transformation: his famous The Temple of Nature is subtitled 'the Origin of Society'. This work, rather than proposing in detail a strict transformation of humanity between different stages, instead dwells on Erasmus Darwin's evolutionary mechanism: Erasmus Darwin does not explain each stage one-by-one, trusting his theory of universal organic development, as articulated in
32314-487: The last uncontacted hunter-gatherers are the community of a few hundred individuals on one of the Andaman Islands . The Europeans who first contacted tropical peoples reported that they were unashamedly naked, only occasionally wrapping themselves in capes in colder weather. Many pastoral societies in warmer climates are also minimally clothed or naked while working. This practice continued when western clothing
32528-567: The late Miocene epoch. During this split, chromosome 2 was formed from the joining of two other chromosomes, leaving humans with only 23 pairs of chromosomes, compared to 24 for the other apes. Following their split with chimpanzees and bonobos, the hominins diversified into many species and at least two distinct genera. All but one of these lineages – representing the genus Homo and its sole extant species Homo sapiens – are now extinct. The genus Homo evolved from Australopithecus . Though fossils from
32742-645: The late Paleolithic (40,000 to 60,000 years ago) in which humans became not only anatomically modern, but also behaviorally modern and capable of self-reflection and symbolic interaction. More recent studies place the use of adornment at 77,000 years ago in South Africa, and 90,000—100,000 years ago in Israel and Algeria. While modesty is a factor, often overlooked purposes for body coverings are camouflage used by hunters, body armor, and costumes used to impersonate "spirit-beings". The current empirical evidence for
32956-439: The legal definition of indecent exposure . In the United States, the exposure of female nipples is a criminal offense in many states and is not usually allowed in public. Individual women who have contested indecency laws by baring their breasts in public assert that their behavior is not sexual. In Canada, the law was changed to include a definition of a sexual context in order for behavior to be indecent. The topfreedom movement in
33170-505: The lowest form and then advanced to more complex forms in the same class. In short, the progress of animals was like the development of a foetus. More than just an indistinct analogy, this parallel between embryology and species development had the status of a genuine causal mechanism in Chambers' theory: more advanced species developed longer as embryos into all their complexity. Motivated by this comparison, Chambers ascribed development to
33384-485: The mind of man and that that mind designed them, like all tools, to "meet and checkmate" the unrestrained competition of natural forces. Ward agreed with Spencer that authoritarian governments repress the talents of the individual, but he believed that modern democratic societies, which minimized the role of religion and maximized that of science, could effectively support the individual in his or her attempt to fully utilize their talents and achieve happiness. He believed that
33598-426: The modern scientific method ) whereas there is no such intelligence and awareness guiding the non-human world. Plants and animals adapt to nature; man shapes nature. While Spencer believed that competition and "survival of the fittest" benefited human society and sociocultural evolution, Ward regarded competition as a destructive force, pointing out that all human institutions, traditions and laws were tools invented by
33812-412: The natural process of evolution was dangerous and had to be avoided at all costs. Such views were naturally coupled to the pressing political and economic questions of the time. Spencer clearly thought society's evolution brought about a racial hierarchy with Caucasians at the top and Africans at the bottom. This notion is deeply linked to the colonial projects European powers were pursuing at the time, and
34026-461: The nature of society and of culture. Similarly, effective colonial administration required some degree of understanding of other cultures. Emerging theories of sociocultural evolution allowed Europeans to organise their new knowledge in a way that reflected and justified their increasing political and economic domination of others: such systems saw colonised people as less evolved, and colonising people as more evolved. Modern civilization (understood as
34240-481: The next: the dialectic of class, land and gender creates growth. Thus, Knight conceptualised a theory of history founded in inevitable racial conflict, with Greece representing 'freedom' and Egypt 'cold inactive stupor'. Buffon, Linnaeus, Camper and Monboddo variously forward diverse arguments about racial hierarchy, grounded in early theories of species change––though many thought that environmental changes could create dramatic changes in form without permanently altering
34454-652: The norm, and sped up following the passage of Title IX of the Education Amendments of 1972 . Eventually all pools use became mixed-gender, and in the 21st century, the practice of male nude swimming is largely forgotten, or denied as having ever existed. Social acceptance of mixed gender nudity due to sauna culture is associated with greater gender equality, which is highest in Iceland, Norway, Finland and Sweden (the US being #53 of 153 countries listed). America and
34668-424: The number is declining as they cease to be supported by local communities. In Korea , bathhouses are known as Jjimjilbang . Such facilities may include mixed-sex sauna areas where clothing is worn, but bathing areas are gender segregated; nudity is required in those areas. In Russia , communal banyas have been used for over a thousand years, serving both hygienic and social functions. Nudity and mixed sex usage
34882-559: The ongoing mass extinction of other forms of life. Within the last century, humans have explored challenging environments such as Antarctica , the deep sea , and outer space . Human habitation within these hostile environments is restrictive and expensive, typically limited in duration, and restricted to scientific , military , or industrial expeditions. Humans have visited the Moon and made their presence known on other celestial bodies through human-made robotic spacecraft . Since
35096-442: The only primates to have short, relatively flush canine teeth . Humans have characteristically crowded teeth, with gaps from lost teeth usually closing up quickly in young individuals. Humans are gradually losing their third molars , with some individuals having them congenitally absent. Humans share with chimpanzees a vestigial tail, appendix , flexible shoulder joints, grasping fingers and opposable thumbs . Humans also have
35310-560: The opening of Japan to European visitors in the Meiji era (1868–1912), the previously normal states of undress, and the custom of mixed public bathing, became an issue for leaders concerned with Japan's international reputation. A law was established with fines for those that violated the ban on undress. Although often ignored or circumvented, the law had the effect of sexualizing the naked body in situations that had not previously been erotic. Public bathing for purification as well as cleanliness
35524-651: The origin of clothing is from a 2010 study published in Molecular Biology and Evolution . That study indicates that the habitual wearing of clothing began at some point in time between 170,000 and 83,000 years ago based upon a genetic analysis indicating when clothing lice diverged from their head louse ancestors. A 2017 study published in Science estimated that anatomically modern humans evolved 350,000 to 260,000 years ago. Thus, humans were naked in prehistory for at least 90,000 years. The habitual use of clothing
35738-474: The palm of the hand and on the soles of the feet. It is estimated that the worldwide average height for an adult human male is about 171 cm (5 ft 7 in), while the worldwide average height for adult human females is about 159 cm (5 ft 3 in). Shrinkage of stature may begin in middle age in some individuals but tends to be typical in the extremely aged . Throughout history, human populations have universally become taller, probably as
35952-536: The past by European imperial powers to justify existing policies of colonialism and slavery and to justify new policies such as eugenics . Most 19th-century and some 20th-century approaches aimed to provide models for the evolution of humankind as a single entity. However, most 20th-century approaches, such as multilineal evolution , focused on changes specific to individual societies. Moreover, they rejected directional change (i.e. orthogenetic , teleological or progressive change). Most archaeologists work within
36166-424: The past there have been several theories regarding why humans lost their fur, but the need to dissipate body heat remains the most widely accepted evolutionary explanation. Less hair, and an increase in eccrine sweating , made it easier for early humans to cool their bodies when they moved from living in shady forest to open savanna . The ability to dissipate excess body heat was one of the things that made possible
36380-534: The phrase " survival of the fittest "). In many ways, Spencer's theory of " cosmic evolution " has much more in common with the works of Jean-Baptiste Lamarck and Auguste Comte than with contemporary works of Charles Darwin. Spencer also developed and published his theories several years earlier than Darwin. In regard to social institutions, however, there is a good case that Spencer's writings might be classified as social evolutionism. Although he wrote that societies over time progressed – and that progress
36594-432: The pool, in order to eliminate contaminants and inspect swimmers to prohibit use by those with signs of disease. During women's weekly swim hours, simple one-piece suits were allowed and sometimes supplied by the facility to insure hygiene; towels were also supplied. Compared to the acceptance of boys being nude, an instance in 1947 where girls were given the same option lasted only six weeks in Highland Park, Michigan before
36808-464: The population density varies from one region to another, and large stretches of surface are almost completely uninhabited, like Antarctica and vast swathes of the ocean. Most humans (61%) live in Asia; the remainder live in the Americas (14%), Africa (14%), Europe (11%), and Oceania (0.5%). Estimates of the population at the time agriculture emerged in around 10,000 BC have ranged between 1 million and 15 million. Around 50–60 million people lived in
37022-629: The postulated progression, which typically ended with a stage of civilization identical to that of modern Europe, is ethnocentric . They also pointed out that the theory assumes that societies are clearly bounded and distinct, when in fact cultural traits and forms often cross social boundaries and diffuse among many different societies (and are thus an important mechanism of change). Boas in his culture-history approach focused on anthropological fieldwork in an attempt to identify factual processes instead of what he criticized as speculative stages of growth. His approach greatly influenced American anthropology in
37236-588: The power of yin , could nullify the yang of aggressive forces. In India, the conventions regarding proper dress do not apply to monks in some Hindu and Jain sects who reject clothing as worldly. Although overwhelmingly male, there have been female ascetics such as Akka Mahadevi who refused to wear clothing. In Bangladesh , the Mru people have resisted centuries of Muslim and Christian pressure to clothe their nakedness as part of religious conversion. Most retain their own religion, which includes elements of Buddhism and Animism , as well as traditional clothing:
37450-407: The presentation of all young girls who have begun menstruating since the last Quarup and whose time has come to choose a partner. The Awá hunters , the male members of an Indigenous people of Brazil living in the eastern Amazon rainforest , are "completely naked except for a piece of string decorated with bright bird feathers tied to the end of their penises". This minimalist dress code reflects
37664-460: The process and progression of evolution of culture. Morgan had a significant influence on Karl Marx and on Friedrich Engels, who developed a theory of sociocultural evolution in which the internal contradictions in society generated a series of escalating stages that ended in a socialist society (see Marxism ). Tylor and Morgan elaborated the theory of unilinear evolution, specifying criteria for categorising cultures according to their standing within
37878-433: The relative lack of body coverings was one of the first things explorers noticed when they encountered Indigenous peoples of the tropics. Non-western cultures during the period were naked only by comparison to Western norms. The genitals or entire lower body of adults were covered by garments in most situations, while the upper body of both men and women might be unclothed. However, lacking the western concept of shame regarding
38092-408: The result is a tendency toward self-criticism by women, while men are less concerned by the evaluation of others. In patriarchal societies, which include much of the world, norms regarding proper attire and behavior are stricter for women than for men, and the judgements for violation of these norms are more severe. In much of the world, the modesty of women is a matter not only of social custom but of
38306-539: The right to be briefly nude in public as a form of expression protected by the First Amendment , but not on a continuing basis for their own comfort or enjoyment as men are allowed to do. In 2020 the US Supreme Court refused to hear the appeal of three women after the New Hampshire Supreme Court found that the state law does not discriminate against women because it bans nudity, which has traditionally included female breasts. Breastfeeding in public may be forbidden in some jurisdictions, unregulated in others, or protected as
38520-531: The savage era, domestication of animals , agriculture , metalworking in the barbarian era and alphabet and writing in the civilization era. Thus Morgan drew a link between social progress and technological progress. Morgan viewed technological progress as a force behind social progress, and held that any social change —in social institutions , organizations or ideologies—has its beginnings in technological change. Morgan's theories were popularized by Friedrich Engels , who based his famous work The Origin of
38734-512: The scientific cutting edge is precisely the point, since the Vestiges' s influence means it was both the concept of evolution the Victorian public was most likely to experience, and the scientific presupposition laid earliest in the minds of bright young scholars. Chambers propounded a 'principle of development' whereby everything evolved by the same mechanism and towards higher order structure or meaning. In his theory, life advanced through different 'classes', and within each class animals began at
38948-404: The second ( Southern Dispersal ) around 70,000 to 50,000 years ago. H. sapiens proceeded to colonize all the continents and larger islands, arriving in Eurasia 125,000 years ago, Australia around 65,000 years ago, the Americas around 15,000 years ago, and remote islands such as Hawaii , Easter Island , Madagascar , and New Zealand in the years 300 to 1280 CE. Human evolution was not
39162-547: The sense of humanity). The native English term man can refer to the species generally (a synonym for humanity ) as well as to human males. It may also refer to individuals of either sex. Despite the fact that the word animal is colloquially used as an antonym for human , and contrary to a common biological misconception , humans are animals . The word person is often used interchangeably with human , but philosophical debate exists as to whether personhood applies to all humans or all sentient beings , and further if
39376-400: The social connotations of low status and deprivation rather than shame regarding sexuality. Slaves might not be provided with clothing. Other workers would be naked while performing many tasks, particularly if hot, dirty, or wet; farmers, fishermen, herders, and those working close to fires or ovens. Only the upper classes were habitually dressed. It was not until the later periods, in particular
39590-509: The society. Spencer "imagined a kind of feedback loop between mental and social evolution: the higher the mental powers the greater the complexity of the society that the individuals could create; the more complex the society, the greater the stimulus it provided for further mental development. Everything cohered to make progress inevitable or to weed out those who did not keep up." Regardless of how scholars of Spencer interpret his relation to Darwin, Spencer became an incredibly popular figure in
39804-421: The species again in a developmental stage-process. In the late 18th century, the Marquis de Condorcet (1743–1794) listed ten stages, or "epochs", each advancing the rights of man and perfecting the human race. Erasmus Darwin (1731-1802), Charles Darwin's grandfather, was an enormously influential natural philosopher, physiologist and poet whose remarkably insightful ideas included a statement of transformism and
40018-449: The species or causing species transformation. However, their arguments still bear on race: Rousseau, Buffon and Monboddo cite orangutans as evidence of an earlier prelinguistic human type, and Monboddo even insisted Orangutans and certain African and South Asian races were identical. Other than Erasmus Darwin, the other pre-eminent scientific text with a theory of cultural transformation was advanced by Robert Chambers (1802-1871). Chambers
40232-489: The spirit of the hunt and being overdressed may be considered ridiculous or inappropriate. The Western world inherited contradictory cultural traditions relating to nudity in various contexts. The first tradition came from the ancient Greeks, who saw the naked body as the natural state and as essentially positive. The second is based upon the Abrahamic religions —Judaism, Christianity, and Islam—which view being naked as shameful and essentially negative. The interaction between
40446-424: The stated purpose of regaining a natural connection to the human body and nature, sometimes in private spaces but also in public. Naturism in the United States, meanwhile, remains largely confined to private facilities, with few "clothing optional" public spaces compared to Europe. In spite of the liberalization of attitudes toward sex, Americans remain uncomfortable with complete nudity. The moral ambiguity of nudity
40660-419: The strength of the sex drive inherent in all animals, Malthus argued, populations tend to grow geometrically, and population growth is only checked by the limitations of economic growth, which, if there would be growth at all, would quickly be outstripped by population growth, causing hunger, poverty, and misery. Far from being the consequences of economic structures or social orders, this "struggle for existence"
40874-465: The strong emphasis on specialisation and the increased profits stemming from a division of labour, Smith's thinking also exerted some direct influence on Darwin himself. Both in Darwin's theory of the evolution of species and in Smith's accounts of political economy, competition between selfishly functioning units plays an important and even dominating rôle. Similarly occupied with economic concerns as Smith, Thomas R. Malthus (1766–1834) warned that given
41088-433: The term "humans" with all members of the genus Homo , in common usage it generally refers to Homo sapiens , the only extant member. All other members of the genus Homo , which are now extinct, are known as archaic humans , and the term "modern human" is used to distinguish Homo sapiens from archaic humans. Anatomically modern humans emerged around 300,000 years ago in Africa, evolving from Homo heidelbergensis or
41302-407: The theories in Herbert Spencer's tradition. Walter Bagehot (1872) applied selection and inheritance to the development of human political institutions. Samuel Alexander (1892) discusses the natural selection of moral principles in society. William James (1880) considered the 'natural selection' of ideas in learning and scientific development. In fact, he identified a 'remarkable parallel […] between
41516-400: The theories reviewed above did not advance a precise understanding of how Darwin's mechanism extended and applied to cultures beyond a vague appeal to competition. Ritchie's Darwinism and Politics (1889) breaks this trend, holding that "language and social institutions make it possible to transmit experience quite independently of the continuity of race." Hence Ritchie saw cultural evolution as
41730-458: The tradition of triumphant historical stages, beginning with Lucretius and reaching Adam Smith––but just for the first four books. In his final books, Knight then grapples with the French revolution and wealthy decadence. Confronted with these twin issues, Knight's theory ascribes progress to conflict: 'partial discord lends its aid, to tie the complex knots of general harmony'. Competition in Knight's mechanism spurs development from any one stage to
41944-427: The transition are scarce, the earliest members of Homo share several key traits with Australopithecus . The earliest record of Homo is the 2.8 million-year-old specimen LD 350-1 from Ethiopia , and the earliest named species are Homo habilis and Homo rudolfensis which evolved by 2.3 million years ago. H. erectus (the African variant is sometimes called H. ergaster ) evolved 2 million years ago and
42158-420: The unclothed body. The social humiliation of nakedness was not associated with sin or shame regarding sexuality, which was unique to Abrahamic societies. For millennia from Mesopotamia to the Middle Kingdom of Egypt the majority of men and women wore a cloth wrapped or tied to cover the lower part of the body. Both men and women would be bare-chested and barefoot . Complete nakedness was embarrassing due to
42372-502: The upper classes was such that nudity was of no concern for men, and for women only if seen by their social superiors. At the Roman baths ( thermae ), which had social functions similar to a modern beach, mixed nude bathing may have been the norm up to the fourth century CE. The encounter between the Indigenous cultures of Africa, the Americas and Oceania with Europeans had a significant effect on all cultures. Because clothing and body adornments are such an important part of cultural meaning,
42586-542: The use of baths and saunas that provided alternatives to sexualization . The spread of Western concepts of modest dress was part of colonialism, and continues today with globalization. Contemporary social norms regarding nudity reflect cultural ambiguity towards the body and sexuality, and differing conceptions of what constitutes public versus private spaces. Norms relating to nudity are different for men than they are for women. Individuals may intentionally violate norms relating to nudity; those without power may use nudity as
42800-537: The work of Charles Darwin (1809-1882) and were popular from late in the 19th century to the end of World War I . The 19th-century unilineal evolution theories claimed that societies start out in a primitive state and gradually become more civilized over time; they equated the culture and technology of Western civilization with progress . Some forms of early sociocultural-evolution theories (mainly unilineal ones) have led to much-criticised theories like social Darwinism and scientific racism , sometimes used in
43014-565: The workplace. To Durkheim, the most important factor in social progress is the division of labour . This was later used in the mid-1900s by the economist Ester Boserup (1910–1999) to attempt to discount some aspects of Malthusian theory . Ferdinand Tönnies (1855–1936) describes evolution as the development from informal society, where people have many liberties and there are few laws and obligations, to modern, formal rational society, dominated by traditions and laws, where people are restricted from acting as they wish. He also notes that there
43228-430: The world as it is including all possessions may practice nudism, or use nakedness as a protest against an unjust world. Many of the negative associations of nakedness are the inverse of positive ones. If nudity is truth, nakedness may be an invasion of privacy or the exposure of uncomfortable truths, a source of anxiety. To be deprived of clothes is punishment, humiliating and degrading. Rather than being natural, nakedness
43442-440: The world's 3.4 billion rural population. Problems for humans living in cities include various forms of pollution and crime , especially in inner city and suburban slums . Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology. The dental formula of humans is: 2.1.2.3 2.1.2.3 . Humans have proportionately shorter palates and much smaller teeth than other primates. They are
43656-460: Was a Scottish evolutionary thinker and philosopher who, though he was then and now perceived as scientifically inadequate and criticized by prominent contemporaries, is important because he was so widely read. There are records of everyone from Queen Victoria to individual dockworkers enjoying his Robert Chambers' Vestiges of the Natural History of Creation (1844), including future generations of scientists. That The Vestiges did not establish itself as
43870-403: Was accomplished through competition – he stressed that the individual rather than the collectivity is the unit of analysis that evolves; that, in other words, evolution takes place through natural selection and that it affects social as well as biological phenomenon. Nonetheless, the publication of Darwin's works proved a boon to the proponents of sociocultural evolution, who saw
44084-543: Was challenged in 1986 by nine women who exposed their breasts in a public park, which led to nine years of litigation culminating with an opinion by the Court of Appeals that overturned the convictions on the basis of the women's actions not being lewd, rather than overturning the law as unconstitutional on the basis of equal protection , which is what the women sought. While the decision gave women more freedom to be topfree (e.g. while sunbathing ), it did not give them equality with men. Other court decisions have given individuals
44298-446: Was compared to a biological organism, and social science equivalents of concepts like variation , natural selection , and inheritance were introduced as factors resulting in the progress of societies. The idea of progress led to that of a fixed "stages" through which human societies progress, usually numbering three – savagery, barbarism, and civilization – but sometimes many more. At that time, anthropology
44512-506: Was first introduced; for example Aboriginal Australians in 1819 wore only the jackets they were given, but not pants. Western ambivalence could be expressed by responding to the nakedness of natives as either a sign of rampant sexuality or of the innocence that preceded the " fall of man ". Norms related to nudity are associated with norms regarding personal freedom , human sexuality , and gender roles , which vary widely among contemporary societies. Situations where private or public nudity
44726-616: Was only regarding adults, it being generally accepted that boys at English beaches would be nude. This prompted complaints by visiting Americans, but Englishmen had no objection to their daughters being fully dressed on the beach with naked boys. In the United States and other Western countries for much of the 20th century, male nudity was the norm in gender segregated activities including summer camps, swimming pools and communal showers based on cultural beliefs that females need more privacy than males. Beginning in 1900, businessmen swam nude at private athletic clubs in New York City, which ended with
44940-487: Was rising as a new scientific discipline, separating from the traditional views of "primitive" cultures that was usually based on religious views. Already in the 18th century, some authors began to theorize on the evolution of humans. Montesquieu (1689–1755) wrote about the relationship laws have with climate in particular and the environment in general, specifically how different climatic conditions cause certain characteristics to be common among different people. He likens
45154-412: Was the evolution of human intentionality: Veblen labelled men 'a creature of habit' and thought that habits were 'mentally digested' from those who influenced him. In short, as Hodgson and Knudsen point out, Veblen thinks: "the changing institutions in their turn make for a further selection of individuals endowed with the fittest temperament, and a further adaptation of individual temperament and habits to
45368-402: Was the first archaic human species to leave Africa and disperse across Eurasia. H. erectus also was the first to evolve a characteristically human body plan . Homo sapiens emerged in Africa around 300,000 years ago from a species commonly designated as either H. heidelbergensis or H. rhodesiensis , the descendants of H. erectus that remained in Africa. H. sapiens migrated out of
45582-451: Was the most complex of the sciences and that true sociogenesis was impossible without considerable research and experimentation. Émile Durkheim, another of the "fathers" of sociology , developed a dichotomal view of social progress. His key concept was social solidarity , as he defined social evolution in terms of progressing from mechanical solidarity to organic solidarity . In mechanical solidarity, people are self-sufficient, there
45796-417: Was typical for much of this history. Bathing facilities in homes threatened the existence of public banyas, but social functions maintained their popularity. Prior to the European colonization of New Zealand , Māori people went naked or partially clothed in casual settings as the climate allowed, although they did wear clothing to keep out the weather and denote social status. Men frequently wore nothing but
