 Most hypotheses aim to determine the reason helpers selectively reduce their fitness and take on an alloparental role.Kin selection is the evolutionary strategy of aiding the reproductive success of related organisms, even at a cost to the own individual's direct fitness.Hamilton's rule (rB−C>0) explains that kin selection will exist if the genetic relatedness (r) of the aided recipient to the aiding individual, times the benefit to the aid recipient (B) is greater than the cost to the aiding individual(C).
