Social Selection
Social selection is a term used with varying meanings in biology. Joan Roughgarden proposed a hypothesis called ''social selection'' as an alternative to sexual selection. Social selection is argued to be a mode of natural selection based on reproductive transactions and a two-tiered approach to evolution and the development of social behavior. Reproductive transactions refer to a situation where one organism offers assistance to another in exchange for access to reproductive opportunity. The two tiers of the theory are behavioral and population genetic. The genetic aspect states that anisogamy arose to maximize contact rate between gametes. The behavioral aspect is concerned with cooperative game theory and the formation of social groups to maximize the production of offspring. In her critique against the neo-Darwinian defense of sexual selection, Roughgarden outlines exceptions to many of the assumptions that come with sexual selection. These exceptions include sexually mono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gender
Gender is the range of social, psychological, cultural, and behavioral aspects of being a man (or boy), woman (or girl), or third gender. Although gender often corresponds to sex, a transgender person may identify with a gender other than their sex assigned at birth. Most cultures use a gender binary, in which gender is divided into two categories, and people are considered part of one or the other;Kevin L. Nadal, ''The Sage Encyclopedia of Psychology and Gender'' (2017, ), p. 401: "Most cultures currently construct their societies based on the understanding of gender binary—the two gender categorizations (male and female). Such societies divide their population based on biological sex assigned to individuals at birth to begin the process of gender socialization." those who are outside these groups may fall under the umbrella term '' non-binary''. Some societies have ''third genders'' (and ''fourth genders'', etc.) such as the hijras of South Asia and two-spirit per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolutionary Medicine
Evolutionary medicine or Darwinian medicine is the application of modern evolutionary theory to understanding health and disease. Modern biomedical research and practice have focused on the molecular and physiological mechanisms underlying health and disease, while evolutionary medicine focuses on the question of why evolution has shaped these mechanisms in ways that may leave us susceptible to disease. The evolutionary approach has driven important advances in the understanding of cancer, autoimmune disease, and anatomy. Medical schools have been slower to integrate evolutionary approaches because of limitations on what can be added to existing medical curricula. The International Society for Evolution, Medicine and Public Health coordinates efforts to develop the field. It owns the Oxford University Press journal ''Evolution, Medicine and Public Health'' and ''The Evolution and Medicine Review''. Core principles Utilizing the Delphi method, 56 experts from a variety of d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychopathy
Psychopathy, or psychopathic personality, is a personality construct characterized by impaired empathy and remorse, along with bold, disinhibited, and egocentric traits. These traits are often masked by superficial charm and immunity to stress, which create an outward appearance of apparent normalcy. Hervey M. Cleckley, an American psychiatrist, influenced the initial diagnostic criteria for antisocial personality reaction/disturbance in the '' Diagnostic and Statistical Manual of Mental Disorders'' (DSM), as did American psychologist George E. Partridge. The DSM and ''International Classification of Diseases'' (ICD) subsequently introduced the diagnoses of antisocial personality disorder (ASPD) and dissocial personality disorder (DPD) respectively, stating that these diagnoses have been referred to (or include what is referred to) as psychopathy or sociopathy. The creation of ASPD and DPD was driven by the fact that many of the classic traits of psychopathy were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free-rider Problem
In economics, the free-rider problem is a type of market failure that occurs when those who benefit from resources, public goods and common pool resources do not pay for them or under-pay. Free riders may overuse common pool resources by not paying for them, neither directly through fees or tolls, nor indirectly through taxes. Consequently, the common pool resource may be under-produced, overused, or degraded. Additionally, despite evidence that people tend to be cooperative by nature (a prosocial behaviour), the presence of free-riders has been shown to cause cooperation to deteriorate, perpetuating the free-rider problem. In social science, the free-rider problem is the question of how to limit free riding and its negative effects in these situations, such as the free-rider problem of when property rights are not clearly defined and imposed. The free-rider problem is common with public goods which are non-excludable and non-rivalrous. The non-excludability and non-rivalr ...

Theft
Theft (, cognate to ) is the act of taking another person's property or services without that person's permission or consent with the intent to deprive the rightful owner of it. The word ''theft'' is also used as a synonym or informal shorthand term for some crimes against property, such as larceny, robbery, embezzlement, extortion, blackmail, or receiving stolen property. In some jurisdictions, ''theft'' is considered to be synonymous with '' larceny'', while in others, ''theft'' is defined more narrowly. A person who engages in theft is known as a thief ( thieves). ''Theft'' is the name of a statutory offence in California, Canada, England and Wales, Hong Kong, Northern Ireland, the Republic of Ireland, and the Australian states of South Australia Theft (and receiving). and Victoria. Theft. Elements The '' actus reus'' of theft is usually defined as an unauthorised taking, keeping, or using of another's property which must be accompanied by a '' mens rea'' of ...

Bullying
Bullying is the use of force, coercion, Suffering, hurtful teasing, comments, or threats, in order to abuse, aggression, aggressively wikt:domination, dominate, or intimidate one or more others. The behavior is often repeated and habitual. One essential prerequisite is the perception (by the bully or by others) that an imbalance of physical or Power (social and political), social power exists or is currently present. This perceived presence of physical or Social relation, social imbalance is what distinguishes the behavior from being interpreted or perceived as ''bullying'' from instead being interpreted or perceived as ''Conflict (process), conflict''. Bullying is a subcategory of aggressive behavior characterized by hostility, hostile intent, the goal (whether consciously or subconsciously) of addressing or attempting to Abusive power and control, "fix" the imbalance of power, as well as repetition over a period of time. Bullying can be performed individually or by a group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Band Society
A band society, sometimes called a camp, or in older usage, a horde, is the simplest form of human society. A band generally consists of a small kin group, no larger than an extended family or clan. The general consensus of modern anthropology sees the average number of members of a social band at the simplest level of foraging societies with generally a maximum size of 30 to 50 people. Origins of usage in anthropology 'Band' was one of a set of three terms employed by early modern ethnography to analyse aspects of hunter-gatherer foraging societies. The three were respectively 'horde,' 'band', and 'tribe'. The term 'horde', formed on the basis of a Turkish/Tatar word ''úrdú'' (meaning 'camp'), was inducted from its use in the works of J. F. McLennan by Alfred William Howitt and Lorimer Fison in the mid-1880s to describe a geographically or locally defined division within a larger tribal aggregation, the latter being defined in terms of social divisions categorized in t ...

Exile
Exile or banishment is primarily penal expulsion from one's native country, and secondarily expatriation or prolonged absence from one's homeland under either the compulsion of circumstance or the rigors of some high purpose. Usually persons and peoples suffer exile, but sometimes social entities like institutions (e.g. the Pope, papacy or a Government-in-exile, government) are forced from their homeland. In Roman law, denoted both voluntary exile and banishment as a capital punishment alternative to death. Deportation was forced exile, and entailed the lifelong loss of citizenship and property. Relegation was a milder form of deportation, which preserved the subject's citizenship and property. The term diaspora describes group exile, both voluntary and forced. "Government in exile" describes a government of a country that has relocated and argues its legitimacy from outside that country. Voluntary exile is often depicted as a form of protest by the person who claims it, to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cooperation
Cooperation (written as co-operation in British English and, with a varied usage along time, coöperation) takes place when a group of organisms works or acts together for a collective benefit to the group as opposed to working in competition for selfish individual benefit. In biology, many animal and plant species cooperate both with other members of their own species and with members of other species with whom they have (symbiotic or mutualism (biology), mutualistic) relationships. Among humans Humans cooperate for the same reasons as other animals: immediate benefit, genetic relatedness, and reciprocity, but also for particularly human reasons, such as honesty signaling (indirect reciprocity), cultural group selection, and for reasons having to do with cultural evolution. Language allows humans to cooperate on a very large scale. Certain studies have suggested that fairness affects human cooperation; individuals are willing to punish at their own cost (''altruistic punis ...

Fitness (biology)
Fitness (often denoted w or ω in population genetics models) is a quantitative representation of individual reproductive success. It is also equal to the average contribution to the gene pool of the next generation, made by the same individuals of the specified genotype or phenotype. Fitness can be defined either with respect to a genotype or to a phenotype in a given environment or time. The fitness of a genotype is manifested through its phenotype, which is also affected by the developmental environment. The fitness of a given phenotype can also be different in different selective environments. With asexual reproduction, it is sufficient to assign fitnesses to genotypes. With sexual reproduction, recombination scrambles alleles into different genotypes every generation; in this case, fitness values can be assigned to alleles by averaging over possible genetic backgrounds. Natural selection tends to make alleles with higher fitness more common over time, resulting in Darwini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altruism (biology)
In biology, altruism refers to behaviour by an individual that increases the fitness of another individual while decreasing their own. Altruism in this sense is different from the philosophical concept of altruism, in which an action would only be called "altruistic" if it was done with the conscious intention of helping another. In the behavioural sense, there is no such requirement. As such, it is not evaluated in moral terms—it is the consequences of an action for reproductive fitness that determine whether the action is considered altruistic, not the intentions, if any, with which the action is performed. The term ''altruism'' was coined by the French philosopher Auguste Comte in French, as ''altruisme'', for an antonym of egoism. He derived it from the Italian ''altrui'', which in turn was derived from Latin ''alteri'', meaning "other people" or "somebody else". Altruistic behaviours appear most obviously in kin relationships, such as in parenting, but may also be eviden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
