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 monomo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gender
Gender is the range of characteristics pertaining to femininity and masculinity and differentiating between them. Depending on the context, this may include sex-based social structures (i.e. gender roles) and gender identity. Most cultures use a gender binary, in which gender is divided into two categories, and people are considered part of one or the other (boys/men and girls/women);Kevin L. Nadal, ''The SAGE Encyclopedia of Psychology and Gender'' (2017, ), page 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 specific genders besides "man" and "woman", such as the hijras of South Asia; these are often referred to as ''third gende ...

Theft
Theft 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. Someone who carries out an act of theft may be described 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.

Bullying
Bullying is the use of force, coercion, hurtful teasing or threat, to abuse, aggressively dominate or intimidate. The behavior is often repeated and habitual. One essential prerequisite is the perception (by the bully or by others) of an imbalance of physical or social power. This imbalance distinguishes bullying from conflict. Bullying is a subcategory of aggressive behavior characterized by hostile intent, imbalance of power and repetition over a period of time. Bullying is the activity of repeated, aggressive behavior intended to hurt another individual, physically, mentally or emotionally. Bullying can be done individually or by a group, called mobbing, in which the bully may have one or more followers who are willing to assist the primary bully or who reinforce the bully by providing positive feedback such as laughing. Bullying in school and the workplace is also referred to as "peer abuse". Robert W. Fuller has analyzed bullying in the context of rankism. The Swedish-Nor ...

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 terms of ...

Capital Punishment
Capital punishment, also known as the death penalty, is the state-sanctioned practice of deliberately killing a person as a punishment for an actual or supposed crime, usually following an authorized, rule-governed process to conclude that the person is responsible for violating norms that warrant said punishment. The sentence ordering that an offender is to be punished in such a manner is known as a death sentence, and the act of carrying out the sentence is known as an execution. A prisoner who has been sentenced to death and awaits execution is ''condemned'' and is commonly referred to as being "on death row". Crimes that are punishable by death are known as ''capital crimes'', ''capital offences'', or ''capital felonies'', and vary depending on the jurisdiction, but commonly include serious crimes against the person, such as murder, mass murder, aggravated cases of rape (often including child sexual abuse), terrorism, aircraft hijacking, war crimes, crimes against h ...

Culture
Culture () is an umbrella term which encompasses the social behavior, institutions, and norms found in human societies, as well as the knowledge, beliefs, arts, laws, customs, capabilities, and habits of the individuals in these groups.Tylor, Edward. (1871). Primitive Culture. Vol 1. New York: J.P. Putnam's Son Culture is often originated from or attributed to a specific region or location. Humans acquire culture through the learning processes of enculturation and socialization, which is shown by the diversity of cultures across societies. A cultural norm codifies acceptable conduct in society; it serves as a guideline for behavior, dress, language, and demeanor in a situation, which serves as a template for expectations in a social group. Accepting only a monoculture in a social group can bear risks, just as a single species can wither in the face of environmental change, for lack of functional responses to the change. Thus in military culture, valor is counted a typica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cooperation
Cooperation (written as co-operation in British English) is the process of groups of organisms working or acting together for common, mutual, or some underlying benefit, as opposed to working in competition for selfish benefit. Many animal and plant species cooperate both with other members of their own species and with members of other species (symbiosis or mutualism). 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 punishment'') if they believe that they are being treated unfairly.

Fitness (biology)
Fitness (often denoted w or ω in population genetics models) is the 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 Darwin ... [...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 the fitness of the agent. 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 als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christopher Boehm
Christopher Boehm (1931–2021) was an American cultural anthropologist with a subspecialty in primatology, who researched conflict resolution, altruism, the evolution of morality, and feuding and warfare. He was also the Director of the Jane Goodall Research Center at University of Southern California, a multi-media interactive database focusing on the social and moral behavior of world hunter gatherers. Boehm died on November 23, 2021 at the age of 90. Education Boehm received his Ph.D. in social anthropology from Harvard University in 1972, and was later trained in ethological field techniques (1983). Work Boehm did field work with human societies such as the Navajo People and the Rovca Tribes of Montenegro or Upper Morača River Tribe,"usc" as well as primates such as wild chimpanzees, focusing on questions of morality in an evolutionary context. After analyzing data from 48 human societies spread across the globe, ranging from small hunting and gathering bands to mor ...
