Scientists, indocumented Yosemite's great gray owl Strix nebulosa Yosemitensis as genetically distinct from the great gray owl in western North America Strix nebulosa nebulosa.
Michelangelo 's David is the classical image of youthful male beauty in Western art. A German male model showing a muscular body with sixpack, example of masculinity. Masculinity has its roots in genetics see gender.
In the past, and still among traditional and non-Western cultures, the most common and definitive sign of becoming a man is getting married. In the mid-twentieth century United States, for example, John Wayne might embody one form of masculinity, while Albert Einstein might be seen as masculine, but not in the same "hegemonic" fashion.
Anthropology has shown that masculinity itself has social statusjust like wealth, race and social class. In western culturefor example, greater masculinity usually brings greater social status.
Many English words such as virtue and virile from the Indo-European root vir meaning man reflect this. Masculinity is associated more commonly with adult men than with boys. A great deal is now known about the development of biological masculine characteristics, such as the hormonal changes that make it possible for men to grow a beard.
The process of sexual differentiation specific to the reproductive system of Homo sapiens produces a female by default. The SRY gene on the Y chromosomehowever, interferes with the default process, causing a chain of events that, all things being equal, leads to testes formation, androgen production, and a range of both pre-natal and post-natal hormonal effects covered by the terms masculinization or virilization.
Because masculinization redirects biological processes from the default female route, it is more precisely called defeminization. There is an extensive debate about how children develop gender identities.
In many cultures displaying characteristics not typical to one's gender may become a social problem for the individual. Among men, the exhibition of feminine behavior may be considered a sign of homosexuality, while the same is for a woman who exhibits masculine behavior.
Within sociology such labeling and conditioning is known as gender assumptions and is a part of socialization to better match a culture's mores. The corresponding social condemnation of excessive masculinity may be expressed in terms such as " machismo " or " testosterone poisoning.
While social conditioning obviously plays a role, it can also be observed that certain aspects of the masculine identity exist in almost all human cultures. The historical development of gender role is addressed by such fields as behavioral geneticsevolutionary psychologyhuman ecology and sociobiology.
All human cultures seem to encourage the development of gender roles, through literature, costume and song. Some examples of this might include the epics of Homerthe King Arthur tales in English, the normative commentaries of Confucius or biographical studies of Muhammad.
More specialized treatments of masculinity may be found in works such as the Bhagavad Gita or bushido 's Hagakure. Well into prehistoric culture, men are believed to have assumed a variety of social and cultural roles which are likely similar across many groups of humans.
In hunter-gatherer societies, men were often if not exclusively responsible for all large game killed, the capture and raising of most or all domesticated animals, the building of permanent shelters, the defense of villages, and other tasks where the male physique and strong spatial-cognition were most useful.
As societies have moved away from agriculture as a primary source of jobs, the emphasis on male physical ability has waned. Traditional gender roles for working men typically involved jobs emphasizing moderate to hard manual labor see Blue-collar workeroften with no hope for increase in wage or position.
For poorer men among the working classes, the need to support their families, especially during periods of industrial change and economic decline, forced them to stay in dangerous jobs working long arduous hours, often without retirement. Many industrialized countries have seen a shift to jobs which are less physically demanding, with a general reduction in the percentage of manual labor needed in the work force see White-collar worker.
The male goal in these circumstances is often of pursuing a quality education and securing a dependable, often office-environment, source of income.
