The component of inclusive fitness resulting from helping the survival of relatives containing the same alleles by descent from a common ancestor.
Selection that results from close kin behaving in ways that favour each other, resulting in increased inclusive fitness.
the process whereby an individual's genes are selected by virtue of that individual's increasing the chances that his or her kin's genes will be propagated into the next generation.
A phenomenon of inclusive fitness, used to explain altruistic behavior between related individuals.
the idea that behaviors that help a genetic relative are favored by natural selection
The selection that results from a behaviour or trait that contributes not only directly to the fitness of the organism, but also indirectly (that is, enhancing an individuals fitness by increasing the reproduction of a relative beyond that which could be achieved without the assistance of the relative).
The mode of natural selection that acts on an individual's inclusive fitness.
Selection for traits that lower an individual's personal fitness, but raise a relative's fitness
selection for genetically-based behavior pattern that lowers an individual's own reproduction but raises a relative's fitness; a genetic explanation for selfless behavior among animals
maximize the amount of your genes in the next generation - your behaviour towards another depends on the degree of relatedness, amount of cost, and amount of benefit
A model of the evolution of cooperative behavior. Individuals help relatives because relatives share genes. By helping relatives to survive and reproduce, individuals are helping perpetuate copies of their genes. Do not confuse kin selection with group selection.
A theory that people will exhibit preferences for helping blood relatives because this will increase the odds that their genes will be transmitted to subsequent generations.
The selection of genes due to individuals assisting the survival and reproduction of nondescendant relatives who possess the same genes by common descent.
In evolutionary biology, kin selection refers to changes in gene frequency across generations that are driven at least in part by interactions between related individuals, and this forms much of the conceptual basis of the theory of social evolution. Indeed some cases of evolution by natural selection can only be understood by considering how biological relatives influence the fitness of each other. Under natural selection, a gene encoding a trait that enhances the fitness of each individual carrying it should increase in frequency in the population; and conversely, a gene that lowers the individual fitness of its carriers should be eliminated.
