Kinship selection
WebKin selection is a way of understanding allele frequency change as a consequence of the actions and interactions among individuals who share alleles by recent common descent – ie, kin. As with group selection, it is a consequence of the properties of groups that cause allele frequency change. WebKin selection theory proposes that cooperative invest-ment should be positively correlated with a donor’s kinship to the recipients (Hamilton 1964). Thus, one of the best ways to test for a role of kin selection in the evol-ution of cooperative breeding is to determine whether helpers adjust their helping behaviour according to their
