A general model for kin selection

Inclusive fitness theory is central to our understanding of the evolution of social behaviour. By showing the importance of genetic transmission through nondescendent relatives, it helps to explain the evolution of reproductively altruistic behaviours, such as those observed in the social insects. Inclusive fitness thinking is quantified by Hamilton's rule, but Hamilton's rule has often been criticized for being inexact or insufficiently general. Adopting a genic perspective yields a very general version that remains simple and transparent. -from Author
