William Donald Hamilton (1936â2000) is one of the greatest evolutionary biologists since Darwin, as measured by the sheer number and diversity of studies directly and indirectly inspired by the central insights of his 1963 and 1964 papers [1,2] on social evolution alone: those introducing the concept of inclusive ...

Inclusive fitness is the number of offspring equivalents that an individual rears, rescues or otherwise supports through its behaviour ... The concept serves to explain how natural selection can perpetuate altruism. If there is an "altruism gene" (or complex of genes) that influences an organism's behavior to be helpful and protective of relatives and their offspring, this behavior also increases the proportion of the altruism gene in the population, because relatives are likely to share ...
The idea of inclusive fitness was first proposed in 1932 by British geneticist J.B.S. Haldane in The Causes of Evolution.The theory was later named and developed by British evolutionary biologist William Donald Hamilton, who used inclusive fitness to explain direct (reproductive) and indirect (aided by a relative or a colony member) inheritance of genetic traits associated with altruism.Hamilton presented his inclusive fitness theory in 1963; the following year British evolutionary biologist ...
Inclusive fitness is the theory that the genetic success of individual organisms is often dependent upon the cooperative success of the group. Because multiple organisms in a population can have ...
Inclusive fitness encompasses conventional Darwinian fitness with the addition of behaviors that contribute to an organismâs individual fitness through altruism.An organismâs ultimate goal is to leave the maximum number of viable offspring possible, thereby keeping their genes present within a population.Since relatives of an organism are likely to share common genes, an organism may increase its own fitness by keeping its relatives and offspring viable.
The competition between paradigms is not the sort of battle that can be resolved by proofs. T. S. Kuhn. Introduction. Despite its status as a cornerstone of modern evolutionary biology, inclusive fitness theory, conceptualised and formalised by W. D. Hamilton over 50 years ago [1, 2], is no stranger to misunderstanding and controversy.In the 21 st century version of the controversy E. O. Wilson, author of Sociobiology and erstwhile supporter of inclusive fitness theory [], shifted to ...
First, the exact significance of Grafenâs (2006) results on the maximization of inclusive fitness may easily be missed. They require the assumption of additive separable phenotypic effects on fitness (ruling out phenotypic interactions), which is stronger than additive separable genetic effects.
In 1964, W.D. Hamilton popularised the concept and the major advance in the mathematical treatment of the phenomenon by George R. Price which has become known as Hamilton's rule. In the same year, John Maynard Smith used the actual term kin selection for the first time.

Inclusive fitness definition, the fitness of an individual organism as measured in terms of the survival and reproductive success of its kin, each relative being valued according to the probability of shared genetic information, an offspring or sibling having a value of 50 percent and a cousin 25 percent.

The 15-minute city is a residential urban concept in which all city residents are able to meet most of their needs within a short walk or bicycle ride from their homes. The concept was popularized by Mayor Anne Hidalgo of Paris, who was in turn inspired by French-Colombian scientist Carlos Moreno. It has been described as a "return to a local way of life. 15-minute cities are built from a series of 15-minute neighborhoods, also known as complete communities or walkable neighborhoods.
In evolutionary biology, inclusive fitness is one of two metrics of evolutionary success as defined by W. D. Hamilton in 1964: Personal fitness is the number of offspring that an individual begets Inclusive fitness is the number of offspring equivalents that an individual rears, rescues or otherwise supports through its behaviour An individual's own child, who carries one half of the individual's genes, is defined as one offspring equivalent. A sibling's child, who will carry one ...
In 1963â1964 W. D. Hamilton introduced the concept of inclusive fitness, the only significant elaboration of Darwinian fitness since the nineteenth century. I discuss the origin of the modern fitness concept, providing context for Hamilton's discovery of inclusive fitness in relation to the puzzle of altruism.
Equation (15) sums up the relatedness weighted cost and benefit of social interactions, and is sometimes used as âinclusive fitness" in the literature, in particular in reproductive skew or tug-of-war models (e.g., Johnstone et al. 1999).
Individual genetic interest is the number of copies carried by offspring. Familial genetic interest is carried by close kin, and ethnic genetic interest by oneâs ethnic group. Genetic interests are often confused with âinclusive fitness.â The latter concept was coined by Hamilton (1964) to describe his theory of altruism.
It was introduced in 1964 by W. D. Hamilton , who showed that, under certain circumstances, evolution selects for organisms with the highest inclusive fitness. This result has been interpreted as a design principle: evolved organisms act as if to maximize their inclusive fitness ( 1 , 2 , 8 , 9 , 11 , 12 ).
Bill Hamilton conceived inclusive fitness theory as a general theoretical extension of classical, Darwinian and Fisherian fitness, and also as providing a maximization result on a par with Fisherâs fundamental theorem of natural selection, described in chapter 3. 1 In the preceding chapters we have seen that inclusive fitness theory is indeed general, and able to deal with subtleties such as nonadditive fitness effects, and conditionally expressed phenotypes.
done to the plausibility of models introduced by such a phrase. INCLUSIVE FITNESS AND KIN SELECTION Inclusive fitness is the term coined by Hamilton to describe his theory for the evolution of altruistic traits (37, 38). In this section I include not only Hamilton's theory and extensions of it but the prior theoretical develop-
The idea that relatedness between organisms can help explain social behaviors has been part of evolutionary theory since Darwin, but the theory of inclusive fitness first introduced by Hamilton (1963, 1964) showed how precisely to take relatedness into account (see Dugatkin, 2007, for a historical overview).
Perspective 2 changes the focus from the own fitness of allele bearers to their accumulated fitness effects on different recipients. This is the classic inclusive-fitness interpretation introduced by Hamilton .
Hamilton (1963, 1964) introduced the concept of inclusive fitness and showed that while certain behaviours are detrimental to the individual, they may result in a net increase in the actor's genes in the population.
In evolutionary biology, inclusive fitness is one of two metrics of evolutionary success as defined by W. D. Hamilton in 1964: Personal fitness is the number of offspring that an individual begets Inclusive fitness is the number of offspring equivalents that an individual rears, rescues or otherwise supports through its behaviour An individual's own child, who carries one half of the individual's genes, is defined as one offspring equivalent. A sibling's child, who will carry one-quarter of the
The direct fitness approach fastens attention on a random individual recipient and adds up the effects on its fitness of the behaviour of all actors. An alternative formulation, inclusive fitness, introduced by Hamilton (1964), again takes a random individual but adds up the effects of its behaviour on the fitness of all recipients. This is essentially a re-allocation of the direct fitness effects, each effect being credited to the actor rather than to the recipient.
Hamilton defined inclusive fitness as follows: âInclusive fitness may be imagined as the personal fitness which an individual actually expresses in its production of adult offspring as it becomes after it has been first stripped and then augmented in a certain way. It is stripped of all components which can be considered as due to the individualâs social environment, leaving the fitness which he would express if not exposed to any of the harms or benefits of that environment.
systems on processes of inclusion and exclusion within the framework of a rights-based approach. Inclusive education is understood as a process to ensure the participation and learning of all students. The concept is introduced using a rights-based approach. Realisation of rights is about respecting the
At the centre of the conversation about social inclusion is the concept of disadvantage. Inclusion happens when the barriers and challenges that lead to disadvantage are removed. In doing so everybody has a fair opportunity to participate. In other words, no one has an undue advantage or disadvantage in a given setting.
âKin selectionâ was coined by Maynard Smith Also known as Inclusive Fitness Theory Here, an individual has the tendency to help its relatives The inclusive fitness theory (commonly known as Kin selection) was proposed by Hamilton (1964)- HAMILTONâs RULE let B = Benefit to Recipient let C = Cost to Actor let r = Coefficient of their genetic relatedness In this case, An allele for an altruistic behavior will be favored if: Br â C > 0 r is the probability that homologous alleles present ...
Inclusive education is when all students, regardless of any challenges they may have, are placed in age-appropriate general education classes that are in their own neighborhood schools to receive high-quality instruction, interventions, and supports that enable them to meet success in the core curriculum (Bui, Quirk, Almazan, & Valenti, 2010 ...
Inclusion in education refers to a model wherein students with special needs spend most or all of their time with non-special (general education) needs students. It arise in the context of special education with an individualized education program or 504 plan, and is built on the notion that it is more effective for students with special needs to have said mixed experience for them to be more ...
