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. While various ideas ...
Inclusive fitness is a conceptual framework in evolutionary biology first defined by W. D. Hamilton in 1964. [1] It is primarily used to aid the understanding of how social traits are expected to evolve in structured populations . [ 2 ]
Inclusive Fitness theory has often been interpreted to mean that social behavior per se is a goal of evolution, and also that genes (or individual organisms) are selected to find ways of actively distinguishing the identity of close genetic relatives ‘in order to’ engage in social behaviors with them. [M]any misunderstandings persist.
"The Genetical Evolution of Social Behaviour" is a 1964 scientific paper by the British evolutionary biologist W.D. Hamilton in which he mathematically lays out the basis for inclusive fitness. [1] [2] Hamilton, then only a PhD student, completed his work in London.
The co-operative behaviour of social insects like the honey bee can be explained by kin selection.. Kin selection is a process whereby natural selection favours a trait due to its positive effects on the reproductive success of an organism's relatives, even when at a cost to the organism's own survival and reproduction. [1]
Inclusive fitness theory resolved the issue of how altruism can evolve. Other theories also help explain the evolution of altruistic behavior, including evolutionary game theory, tit-for-tat reciprocity, and generalized reciprocity. These theories help to explain the development of altruistic behavior, and account for hostility toward cheaters ...

Among other things, HBE attempts to explain variation in human behavior as adaptive solutions to the competing life-history demands of growth, development, reproduction, parental care, and mate acquisition. HBE overlaps with evolutionary psychology, human or cultural ecology, and decision theory.
