Abstract

Kin recognition has been widely observed across the animal kingdom. Individuals discriminate and treat conspecifics differently in relation to their genetic relatedness to increase their inclusive fitness (i.e. their own reproductive success and that of their relatives) and to avoid adverse influences from inbreeding. Although most studies on kin recognition have focused on group-living species, this behaviour can also be adaptive in solitary species.
