Inclusive fitness in humans is the application of inclusive fitness theory to human social behaviour, relationships and cooperation.. Inclusive fitness theory (and the related kin selection theory) are general theories in evolutionary biology that propose a method to understand the evolution of social behaviours in organisms. In a simulation model of Wilsonet al. Be sure to read and cite the Silk 2002 paper in your post. Inclusive fitness theory is the idea that the evolutionary success of a trait can be calculated as a sum of fitness effects multiplied by relatedness coefficients. In evolutionary biology, it has been suggested that genes are the ultimate controllers of our bodies, our instincts, and even our actions. When we think of "survival of the fittest," we associate selfish behaviors with organisms that are always seeking to live longer and reproduce more successfully. Tuesday, May 3, 2011. Why is altruism a 'problem' for evolutionary theory? The first effect tends to promote and the second to oppose the evolution of altruistic behaviour. Social Evolution and Inclusive Fitness Theory argues that a theory first presented in 1963 by William D. Hamilton—inclusive fitness theory—provides the most fundamental and general explanation for the evolution and maintenance of social behavior in the natural world. To what degree do the theories of kin selection and inclusive fitness solve the altruism 'problem'? What are some examples of altruism that we see often? Rooted in Charles Darwin's evolutionary theory, Evo Psych is equally a part of Biology as it is Psychology. Bill Hamilton's 1963 and 1964 inclusive fitness articles are easily the most cited articles in the entire field of behavioral evolution, and his work on altruism and kinship spurred endless dissertation projects and hundreds of published articles, both theoretical and empirical. 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 Fisher’s fundamental theorem of natural selection, described in chapter 3. This claim is based on using linear regression to split … (1992) these two factors appear to exactly balance one another, thus opposing the evolution of local altruistic behaviour. https://www.khanacademy.org/.../v/mating-behavior-and-inclusive-fitness Evolutionary theory views violence in the context of its likely costs and benefits measured in the currency of the actor’s inclusive fitness. Inclusive fitness provides an evolutionary explanation for altruistic behavior among animal communities. Advances in modern evolutionary theory heralded by inclusive fitness theory and the “gene’s-eye” perspective guide researchers to phenomena Darwin could not have envisioned, such as inherent and predictable forms of within-family conflict and sexual conflict between males and females. Despite recent mathematical analyses demonstrating the limitations of this approach, its adherents claim that it is as general as the theory of natural selection itself. But inclusive fitness … Violence is one potential means of resolving conflicts over scarce resources for survival and reproduction.
