Light skin pigmentation protects against depletion of vitamin D , which requires sunlight to make. There is relatively little variation between human geographical populations, and most of the variation that occurs is at the individual level.
Genetic data shows that no matter how population groups are defined, two people from the same population group are almost as different from each other as two people from any two different population groups.
Current genetic research has demonstrated that human populations native to the African continent are the most genetically diverse.
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.
While many of the common variants found in populations outside of Africa are also found on the African continent, there are still large numbers which are private to these regions, especially Oceania and the Americas.
This ancestry is thought to originate from admixture with an unknown archaic hominin that diverged before the split of Neanderthals and modern humans.
The greatest degree of genetic variation exists between males and females. While the nucleotide genetic variation of individuals of the same sex across global populations is no greater than 0.
Women have lighter skin than men of the same population; this has been explained by a higher need for vitamin D in females during pregnancy and lactation.
As there are chromosomal differences between females and males, some X and Y chromosome related conditions and disorders only affect either men or women.
After allowing for body weight and volume, the male voice is usually an octave deeper than the female voice. Human variation is highly non-concordant: many of the genes do not cluster together and are not inherited together.
Skin and hair color are mostly not correlated to height, weight, or athletic ability. Humans do not share the same patterns of variation through geography.
Dark-skinned populations that are found in Africa, Australia, and South Asia are not closely related to each other. Despite this, genetic boundaries around local populations do not biologically mark off any fully discrete groups of humans.
Much of human variation is continuous, often with no clear points of demarcation. The human brain , the focal point of the central nervous system in humans, controls the peripheral nervous system.
In addition to controlling "lower," involuntary, or primarily autonomic activities such as respiration and digestion , it is also the locus of "higher" order functioning such as thought , reasoning , and abstraction.
Humans have a larger and more developed prefrontal cortex than other primates, the region of the brain associated with higher cognition.
There are some traits that, although not strictly unique, do set humans apart from other animals. Humans are generally diurnal. The average sleep requirement is between seven and nine hours per day for an adult and nine to ten hours per day for a child; elderly people usually sleep for six to seven hours.
Having less sleep than this is common among humans, even though sleep deprivation can have negative health effects. 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.
During sleep humans dream, where they experience sensory images and sounds. Dreaming is stimulated by the pons and mostly occurs during the REM phase of sleep.
The events in dreams are generally outside the control of the dreamer, with the exception of lucid dreaming , where the dreamer is self-aware.
Human consciousness, at its simplest, is " sentience or awareness of internal or external existence".
Some philosophers divide consciousness into phenomenal consciousness, which is experience itself, and access consciousness, which is the processing of the things in experience.
Historically it is associated with introspection , private thought , imagination and volition. It may be 'awareness', or ' awareness of awareness ', or self-awareness.
The process of acquiring knowledge and understanding through thought, experience, and the senses is known as cognition.
Cognitive psychology studies cognition , the mental processes' underlying behavior. Psychologists have developed intelligence tests and the concept of intelligence quotient in order to assess the relative intelligence of human beings and study its distribution among population.
Human motivation is not yet wholly understood. From a psychological perspective, Maslow's hierarchy of needs is a well-established theory which can be defined as the process of satisfying certain needs in ascending order of complexity.
Furthermore, incentive and preference are both factors, as are any perceived links between incentives and preferences. Volition may also be involved, in which case willpower is also a factor.
Ideally, both motivation and volition ensure the selection, striving for, and realization of goals in an optimal manner, a function beginning in childhood and continuing throughout a lifetime in a process known as socialization.
Emotions are biological states associated with the nervous system   brought on by neurophysiological changes variously associated with thoughts, feelings, behavioural responses, and a degree of pleasure or displeasure.
Emotion has a significant influence on human behavior and their ability to learn. Emotional experiences perceived as pleasant , such as joy , interest or contentment , contrast with those perceived as unpleasant , like anxiety , sadness , anger , and despair.
The definition of happiness is a common philosophical topic. Some define as experiencing the feeling of positive emotionial affects , while avoiding the negative ones.
For humans, sexuality involves biological , erotic , physical , emotional , social , or spiritual feelings and behaviors.
Studies show that men desire sex more than women and masturbate more often. Humans can fall anywhere along a continuous scale of sexual orientation ,  although most humans are heterosexual.
Love most commonly refers to a feeling of strong attraction or emotional attachment. It can be impersonal the love of an object, ideal, or strong political or spiritual connection or interpersonal love between two humans.
Humanity's unprecedented set of intellectual skills were a key factor in the species' eventual technological advancement and concomitant domination of the biosphere.
The division of humans into male and female gender roles has been marked culturally by a corresponding division of norms, practices , dress, behavior, rights, duties , privileges , status , and power.
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.
While many species communicate , language is unique to humans, a defining feature of humanity, and a cultural universal. Language differs from other forms of communication in that it is modality independent ; the same meanings can be conveyed through different media, auditively in speech, visually by sign language or writing, and even through tactile media such as braille.
Art is a defining characteristics of humans and there is evidence for a relationship between creativity and language. These include allowing them to better problem solve issues, providing a means to control or influence other humans, encouraging cooperation and contribution within a society or increasing the chance of attracting a potential mate.
Evidence of humans engaging in musical activities predates cave art and so far music has been practised by all human cultures. Unlike speaking, reading and writing does not come naturally to humans and must be taught.
Stone tools were used by proto-humans at least 2. Religion is generally defined as a belief system concerning the supernatural , sacred or divine , and practices, values , institutions and rituals associated with such belief.
Some religions also have a moral code. The evolution and the history of the first religions have recently become areas of active scientific investigation.
There is no accepted academic definition of what constitutes religion. Although the exact level of religiosity can be hard to measure,  a majority of humans professes some variety of religious or spiritual belief.
This includes humans who have no religious beliefs or do not identify with any religion. 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.
The first coincides with the Hellenistic period and the second with the Renaissance. All of science can be divided into three major branches, the formal sciences e.
Philosophy is a field of study where humans seek to understand fundamental truths about themselves and the world in which they live.
Society is the system of organizations and institutions arising from interaction between humans. Humans are highly social beings and tend to live in large complex social groups.
They can be divided into different groups according to their income, wealth, power , reputation and other factors. The first forms of human social organization were families living in band societies as hunter-gatherers.
All human societies organize, recognize and classify types of social relationships based on relations between parents, children and other descendants consanguinity , and relations through marriage affinity.
There is also a third type applied to godparents or adoptive children fictive. These culturally defined relationships are referred to as kinship.
In many societies it is one of the most important social organizing principle and plays a role in transmitting status and inheritance. Human ethnic groups are a social category who identify together as a group based on shared attributes that distinguish them from other groups.
These can be a common set of traditions, ancestry , language , history , society , culture , nation , religion , or social treatment within their residing area.
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.
The early distribution of political power was determined by the availability of fresh water , fertile soil , and temperate climate of different locations.
This led to the development of governance within and between the communities. Governments create laws and policies that affect the citizens that they govern.
There have been multiple forms of government throughout human history, each having various means of obtaining power and ability to exert diverse controls on the population.
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.
Early human economies were more likely to be based around gift giving instead of a bartering system.
Humans willingness to kill other members of their species en masse though organised conflict has long been the subject of debate.
One school of thought is that it has evolved as a means to eliminate competitors and has always been an innate human characteristic.
The other suggests that war is a relatively recent phenomenon and appeared due to changing social conditions. From Wikipedia, the free encyclopedia.
