<P> According to Hamilton 's rule , kin selection causes genes to increase in frequency when the genetic relatedness of a recipient to an actor multiplied by the benefit to the recipient is greater than the reproductive cost to the actor . Hamilton proposed two mechanisms for kin selection . First , kin recognition allows individuals to be able to identify their relatives . Second , in viscous populations , populations in which the movement of organisms from their place of birth is relatively slow , local interactions tend to be among relatives by default . The viscous population mechanism makes kin selection and social cooperation possible in the absence of kin recognition . In this case , nurture kinship , the treatment of individuals as kin as a result of living together , is sufficient for kin selection , given reasonable assumptions about population dispersal rates . Note that kin selection is not the same thing as group selection , where it instead is proposed that natural selection acts on the group as a whole . </P>
