[304] One of the oldest surviving works of literature is the Epic of Gilgamesh, first engraved on ancient Babylonian tablets about 4,000 years ago. [315], Religion is generally defined as a belief system concerning the supernatural, sacred or divine, and practices, values, institutions and rituals associated with such belief. Body size is partly determined by genes and is also significantly influenced by environmental factors such as diet, exercise, and sleep patterns. We'd just like to take a moment to apologise for the continued delays the site is currently experiencing. The splitting date between human and chimpanzee lineages is placed 4–8 million years ago, during the late Miocene epoch. While one in five Europeans is 60 years of age or older, only one in twenty Africans is 60 years of age or older. [259] Recent research suggests that being happy might involve experiencing some negative emotions when humans feel they are warranted. Video extended to full song length with Twister scenes.May 2015 - Now there's a newer edit: https://www.youtube.com/watch?v=bSrz_XdRRxI [237] It now often includes some kind of experience, cognition, feeling or perception. They are the only extant members of the subtribe Hominina and—together with chimpanzees, gorillas, and orangutans—are part of the family Hominidae (the great apes, or hominids). Until the development of agriculture approximately 10,000 years ago, Homo sapiens employed a hunter-gatherer method as their sole means of food collection. ". [224], Humans are generally diurnal. This led to the development of governance within and between the communities. [227] Humans have three to five dreams per night, and some may have up to seven;[228] however most dreams are immediately or quickly forgotten. In some cases, dietary restrictions in humans can lead to deficiency diseases; however, stable human groups have adapted to many dietary patterns through both genetic specialization and cultural conventions to use nutritionally balanced food sources. [137] The variation in human DNA is very small compared to other species, possibly suggesting a population bottleneck during the Late Pleistocene (around 100,000 years ago), in which the human population was reduced to a small number of breeding pairs. Studies show that men desire sex more than women and masturbate more often. Humans create complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. [175] Skin color tends to vary clinally and general correlates with the level of ultraviolet radiation in a particular geographic area, with darker skin mostly around the equator. The human body is an extremely complex structure made of many different cells, tissues and organ systems. Humans also have an abundance of sweat glands, called eccrine glands. [54] The pattern of encephalization started with Homo habilis which at approximately 600 cm3 (37 cu in) had a brain slightly larger than chimpanzees, and continued with Homo erectus (800–1,100 cm3 (49–67 cu in)), and reached a maximum in Neanderthals with an average size of 1,200–1,900 cm3 (73–116 cu in), larger even than Homo sapiens (but less encephalized). This change in diet may also have altered human biology; with the spread of dairy farming providing a new and rich source of food, leading to the evolution of the ability to digest lactose in some adults. [244][245] This may focus on intellectual, cognitive, neural, social, or moral development. Social interactions between humans have established an extremely wide variety of values,[13] social norms, and rituals, which together undergird human society. [106][107], Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology. The _____ of human beings are also called primary needs. [343] Human groups range from the size of families to nations. [363][364] Evidence suggests early H. sapiens made use of long-distance trade routes to exchange goods and ideas, leading to cultural explosions and providing additional food sources when hunting was sparse, while such trade networks did not exist for the now extinct Neanderthals. Oxford University Press. The mental abilities of humans are remarkable compared to other apes. As of 2018[update], the global average life expectancy at birth of a girl is estimated to be 74.9 years compared to 70.4 for a boy. Humans, like other animal species, have a typical life course that consists of successive phases of growth, each characterized by a distinct set of physical, physiological, and behavioral features. Humans evolved that way because changes in the climate 200,000 years ago that demanded that they travel long distances for food and water. During the next million years a process of encephalization began, and with the arrival of Homo erectus in the fossil record, cranial capacity had doubled. [251][252] They are often intertwined with mood, temperament, personality, disposition, creativity,[253] and motivation. [370] Early money consisted of commodities; the oldest being in the form of cattle and the most widely used being cowrie shells. With the amount of information that is available to us at one time, the human mind has naturally developed shortcuts that allow us to function more efficiently in a social world. Mike Tatman. Human rights are rights inherent to all human beings, regardless of race, sex, nationality, ethnicity, language, religion, or any other status. Kindness over being clever. [111], 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). [331] In 2015 16% or slightly under 1.2 billion humans are irreligious. [122] Humans have the largest number of eccrine sweat glands among species. One school of thought is that it has evolved as a means to eliminate competitors and has always been an innate human characteristic. [36], The earliest fossils that have been proposed as members of the hominin lineage are Sahelanthropus tchadensis, dating from 7 million years ago; Orrorin tugenensis, dating from 5.7 million years ago; and Ardipithecus kadabba, dating to 5.6 million years ago. [82] With the advent of the Information Age at the end of the 20th century, modern humans live in a world that has become increasingly globalized and interconnected. Skin and hair color are mostly not correlated to height, weight, or athletic ability. At this point, most modern cultures recognize the baby as a person entitled to the full protection of the law, though some jurisdictions extend various levels of personhood earlier to human fetuses while they remain in the uterus. [11][12] The spread of the large and increasing population of humans has profoundly affected the biosphere and millions of species worldwide. ", "Humans may have been trading with each for as long as 300,000 years", "8 Trade Routes That Shaped World History", "Why do we need economists and the study of economics?

Humans have characteristically crowded teeth, with gaps from lost teeth usually closing up quickly in young individuals. There is biological variation in the human species—with traits such as blood type, genetic diseases, cranial features, facial features, organ systems, eye color, hair color and texture, height and build, and skin color varying across the globe. Delanty, Gerard & Krishan Kumar (2006) The SAGE Handbook of Nations and Nationalism. APA Press, Cabanac, Michel (2002). Dark-skinned populations that are found in Africa, Australia, and South Asia are not closely related to each other. Humans are the only ape in which the female is intermittently fertile year round, and in which no special signals of fertility are produced by the body (such as genital swelling during estrus). The relationship between all these changes is the subject of ongoing debate. [292], Art is a defining characteristics of humans and there is evidence for a relationship between creativity and language. The evolution and the history of the first religions have recently become areas of active scientific investigation. The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4.2 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.. [176][177][178][179], Human skin color can range from darkest brown to lightest peach, or even nearly white or colorless in cases of albinism. Adult height for each sex in a particular ethnic group approximately follows a normal distribution. A) beliefs B) values C) attitudes D) drives E) thoughts. These human societies subsequently expanded, establishing various forms of government and culture around the world, and unifying people within regions to form states and empires. [136] Human hair ranges in color from white to red to blond to brown to black, which is the most frequent. They are apex predators, being rarely preyed upon by other species. [196][197] On average, men have about 40–50% more upper body strength and 20–30% more lower body strength than women. [103], Humans have had a dramatic effect on the environment. Both overall population numbers and the proportion residing in cities are expected to increase significantly in the coming decades. [226] The length of a dream can vary, from a few seconds up to 30 minutes. [304], Stone tools were used by proto-humans at least 2.5 million years ago. "cros...rd" or "he?p"). To make these glands more efficient, human … 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. We use cookies on The Crossword Solver to help our site work, to understand how it is used and to tailor the advertisements shown on our site. Though most of human existence has been sustained by hunting and gathering in band societies,[14] many human societies transitioned to sedentary agriculture approximately 10,000 years ago,[15] domesticating plants and animals, thus enabling the growth of civilization.

[269] Different forms of love have been described, including familial love (love for family), platonic love (love for friends), romantic love (sexual passion) and guest love (hospitality). In the developing world the median age is between 15 and 20 years. Sickle cell anemia, which may provide increased resistance to malaria, is frequent in populations where malaria is endemic. 4–7. In general, nearly all the Undines closely resemble human beings in appearance and size, though the ones inhabiting small streams and fountains were of correspondingly of lesser proportions.

[165] Around ten thousand years ago, humans developed agriculture,[166] which substantially altered their diet. [6][7][8][9][10] In several waves of migration, H. sapiens ventured out of Africa and populated most of the world. We're working closely with our server provider and will try to get things back to normal as soon as possible.

Human body, the physical substance of the human organism. [351] Ethnic groupings can play a powerful role in the social identity and solidarity of ethno-political units. [16][17][better source needed] The global human population is about 7.8 billion in 2021. [270] Romantic love has been shown to elicit brain responses similar to an addiction. [125][126] Compared to the great apes, human gene sequences—even among African populations—are remarkably homogeneous. [88] Deliberate habitat alteration is often done with the goals of increasing comfort or material wealth, increasing the amount of available food, improving aesthetics, or improving ease of access to resources or other human settlements. The study of human beings is called human biology. In the newborn infant the head represents about a quarter of the total length; in the adult it represents about one-seventh. [288][289] Human language also has the capacity of displacement, using words to represent things and happenings that are not presently or locally occurring, but reside in the shared imagination of interlocutors. [22], The species binomial "Homo sapiens" was coined by Carl Linnaeus in his 18th-century work Systema Naturae. [50] Other significant morphological changes included the evolution of a power and precision grip, a change first occurring in H. [320] It may have evolved to play a role in helping enforce and encourage cooperation between humans. As a consequence of bipedalism, human females have narrower birth canals. [365][366] Early trade likely involved materials for creating tools like obsidian. Human behavior, the potential and expressed capacity for physical, mental, and social activity throughout human life. [81] The Scientific Revolution, Technological Revolution and the Industrial Revolution brought such discoveries as imaging technology, major innovations in transport, such as the airplane and automobile; energy development, such as coal and electricity. However, the differences between the structure of human brains and those of other apes may be even more significant than differences in size. [362], Trade, the voluntary exchange of goods and services, is seen as a characteristic that differentiates humans from other animals and has been cited as a practice that gave Homo sapiens a major advantage over other hominids. [293] The earliest evidence of art was shell engravings made by Homo erectus 300,000 years before humans evolved. [275] Disregarding extinct hominids, humans are the only animals known to teach generalizable information,[276] innately deploy recursive embedding to generate and communicate complex concepts,[277] engage in the "folk physics" required for competent tool design,[278][279] or cook food in the wild. Humans (Homo sapiens) are a species of highly intelligent primates. [261][262] Sexuality also affects and is affected by cultural, political, legal, philosophical, moral, ethical, and religious aspects of life. [156][157] There are significant geographical variations in human life expectancy, mostly correlated with economic development—for example life expectancy at birth in Hong Kong is 84.8 years for girls and 78.9 for boys, while in Eswatini, primarily because of AIDS, it is 31.3 years for both sexes. Humans have a larger and more developed prefrontal cortex than other primates, the region of the brain associated with higher cognition. [citation needed] There are several theories of the adaptational value of bipedalism. [331], An aspect unique to humans is their ability to transmit knowledge from one generation to the next and to continually build on this information to develop tools, scientific laws and other advances to pass on further. Similarly, populations that have for a long time inhabited specific climates, such as arctic or tropical regions or high altitudes, tend to have developed specific phenotypes that are beneficial for conserving energy in those environments—short stature and stocky build in cold regions, tall and lanky in hot regions, and with high lung capacities at high altitudes. Some paleoanthropologists include fossils that others have allocated to different species, while the majority assign only fossils that align anatomically with the species as it exists today. [167][168] Agriculture led to increased populations, the development of cities, and because of increased population density, the wider spread of infectious diseases. The guys at South Park agree if the profoundly funny three-parter Imagination Land is any indication. [305] Beyond simply passing down knowledge the use and sharing of imaginative fiction through stories might have helped develop humans capabilities for communication and increased the likelihood of securing a mate. [247] From a more general, philosophical perspective, human motivation can be defined as a commitment to, or withdrawal from, various goals requiring the application of human ability. This includes humans who have no religious beliefs or do not identify with any religion. This has been closely tied to the rise of the nation state as the predominant form of political organization in the 19th and 20th centuries. Human being definition, any individual of the genus Homo, especially a member of the species Homo sapiens. Agriculture and sedentary lifestyle led to the emergence of early civilizations (the development of urban development, complex society, social stratification and writing) from about 5,000 years ago (the Bronze Age), first beginning in Mesopotamia. The exact influence of genes and environment on certain traits is not well understood. It also has a role to play in the transportation in human beings. Early modern humans are thought to have diverged in Africa from an earlier hominin around 300,000 years ago, with the earliest fossil evidence of Homo sapiens also appearing around 300,000 years ago in Africa. They are anatomically similar and related to the great apes ( orangutans , chimpanzees , bonobos , and gorillas ) but are distinguished by a more highly developed brain that allows for the capacity for articulate speech and abstract reasoning. Human population growth and industrialisation has led to environmental destruction and pollution significantly contributing to the ongoing mass extinction of other forms of life called the Holocene extinction,[83] which may be further accelerated by global warming in the future. Q 56 . Cognitive psychology studies cognition, the mental processes' underlying behavior. Non-African populations, however, acquired new genetic inputs from local admixture with archaic populations, and thus have much greater variation from Neanderthals and Denisovans than is found in Africa. H. erectus were the first of the hominina to leave Africa, between 1.3 to 1.8 million years ago. Apart from bipedalism, humans differ from chimpanzees mostly in smelling, hearing, digesting proteins, brain size, and the ability of language. [256], Emotional experiences perceived as pleasant, such as joy, interest or contentment, contrast with those perceived as unpleasant, like anxiety, sadness, anger, and despair. The other suggests that war is a relatively recent phenomenon and appeared due to changing social conditions. A NOT TRUE before my nephew leaves my home he always looks my dog straight in the eye and says "Delilah. [281] Other traits and behaviors that are mostly unique to humans, include starting fires,[282] phoneme structuring[283] and vocal learning. With the advent of large-scale trade and transport infrastructure, proximity to these resources has become unnecessary, and in many places, these factors are no longer a driving force behind the success of a population. [313] Throughout history, humans have altered their appearance by wearing clothing.

Earlier remains now classified as early Homo sapiens, such as the Jebel Irhoud remains from Morocco and the Florisbad Skull from South Africa, have been dated to about 300,000 and 259,000 years old respectively. “A human being is a part of the whole called by us universe, a part limited in time and space. Typically the gestation period is 38 weeks (9 months). [120][121] 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 the palm of the hand and on the soles of the feet. [326][327], Although the exact level of religiosity can be hard to measure,[328] a majority of humans professes some variety of religious or spiritual belief. What is a human being? As a result, humans are a cosmopolitan species found in almost all regions of the world, including tropical rainforest, arid desert, extremely cold arctic regions, and heavily polluted cities. A sustained restriction of adult sleep to four hours per day has been shown to correlate with changes in physiology and mental state, including reduced memory, fatigue, aggression, and bodily discomfort. [342], Society is the system of organizations and institutions arising from interaction between humans. [355] As farming populations gathered in larger and denser communities, interactions between these different groups increased. Which of the following statements is true about the innate drives of people? [350] Also there is no generally accepted definition on what constitutes an ethnic group. Modern humans, however, have a great capacity for altering their habitats by means of technology, irrigation, urban planning, construction, deforestation and desertification. [361] Many countries have formed international political alliances, the largest being the United Nations with 193 member states. Cultural differences by gender have often been believed to have arisen naturally out of a division of reproductive labor; the biological fact that women give birth led to their further cultural responsibility for nurturing and caring for children. These descendants of H. erectus spread through Eurasia c. 500,000 years ago, evolving into H. antecessor, H. heidelbergensis and H. neanderthalensis. [352][353][354], The early distribution of political power was determined by the availability of fresh water, fertile soil, and temperate climate of different locations. It can be impersonal (the love of an object, ideal, or strong political or spiritual connection) or interpersonal (love between two humans). Dreaming is stimulated by the pons and mostly occurs during the REM phase of sleep. [114] Through history human populations have universally become taller, probably as a consequence of better nutrition, healthcare, and living conditions. [248], Emotions are biological states associated with the nervous system[249][250] brought on by neurophysiological changes variously associated with thoughts, feelings, behavioural responses, and a degree of pleasure or displeasure. [301] Listening to music and observing dance stimulates the orbitofrontal cortex and other pleasure sensing areas of the brain. [158] The developed world is generally aging, with the median age around 40 years. Human presence on other celestial bodies has been the case mainly with human-made robotic spacecraft[93][94][95] and with humans solely on the Moon, two at a time for brief intervals between 1969 and 1972. Among the 23 pairs of chromosomes there are 22 pairs of autosomes and one pair of sex chromosomes. There is also a third type applied to godparents or adoptive children (fictive). Sorry, and we hope you continue to use The Crossword Solver. Humans are able to create new and complex ideas, and to develop technology, which is unprecedented among other organisms on Earth. [336], All of science can be divided into three major branches, the formal sciences (e.g., logic and mathematics), which are concerned with formal systems, the applied sciences (e.g., engineering, medicine), which are focused on practical applications, and the empirical sciences, which are based on empirical observation and are in turn divided into natural sciences (e.g., physics, chemistry, biology) and social sciences (e.g., psychology, economics, sociology). Males on average are 15% heavier and 15 cm (6 in) taller than females. [333] Historians have identified two major scientific revolutions in human history. [271] When in love dopamine, norepinephrine, serotonin and other chemicals stimulate the brain's pleasure center, leading to side effects such as increased heart rate, loss of appetite and sleep, and an intense feeling of excitement. [332] This accumulated knowledge can be tested to answer questions or make predictions about how the universe functions and has been very successful in advancing human ascendancy.

The genes that allow adult humans to digest lactose are present in high frequencies in populations that have long histories of cattle domestication and are more dependent on cow milk. Most researchers believe that skin darkening is an adaptation that evolved as protection against ultraviolet solar radiation. All species of non-human apes are capable of giving birth until death. ", "The Past, Present and Future of Gender Norms", "Why is language unique to humans? As there are chromosomal differences between females and males, some X and Y chromosome related conditions and disorders only affect either men or women. The earliest bipedal hominin is considered to be either Sahelanthropus[52] or Orrorin, with Ardipithecus, a full bipedal,[53] coming somewhat later.
