For nearly 50 years, Inclusive Fitness Theory has provided researchers an avenue to understand altruistic interactions among individuals in a colony. It has recently come under fire by prominent academics suggesting it is unsatisfactory in describing altruism.

Inclusive Fitness, Altruism and Family Adaptation
The Canadian Journal of Psychiatry, 1983An integrative model of family functioning is put forward using a sociobiological framework. Three key socio-biological concepts that have a relevance to family interaction are inclusive fitness, altruism, and a struggle for status. The term ‘inclusive fitness’ encompasses the parents’ own fitness and that of their kith and kin. Altruism refers to how

Relatedness and inclusive fitness with inbreeding
Theoretical Population Biology, 1992Relatedness arising in kin selection theory is measured by a variable taking as values two pedigree indices in populations with inbreeding when selection is weak. This variable reduces to a single pedigree index when inbreeding is caused by partial selfing or partial sib-mating.

Inclusive fitness models with two sexes
Theoretical Population Biology, 1988Much recent work has focused on the transition from G. R. Price's (1970, Nature 227, 520-521) formula for allele frequency change to an inclusive fitness condition for the selective advantage of a certain behaviour. In case there is any kind of asymmetry between the sexes, the analysis must keep track of the two sexes separately, and this leads to a ...

Journal of Theoretical Biology, 1979
Abstract Hamilton implicitly defined the inclusive fitness of an individual as the number of genomes, identical by descent to its own, but not in its own body, which owe their existence to expression of genes in said individual. Hamilton regarded inclusive fitness as the true metric of evolutionary success and the thin- maximized by selection ...

Inclusive fitness and sex allocation
1996Abstract An important point in understanding the function and evolution of social insects lies in understanding how the workers can increase their own fitness.. In the first chapter we already learnt that workers can play an active role in the evolution of social life, and when doing this they can run into conflicts with the queens, at ...

Inclusive Fitness and Hamilton’s Rule
2015This chapter examines how the logic of inclusive fitness theory can be mathematically formalized using the Price equation, and how that formalization can be used to derive Hamilton's rule in its simplest form, as applied to unconditional behaviors having additive effects on fitness.
