Kin-biased behavior relies on the ability to recognize relatives, and animals may use various cues for this purpose. The hypotheses proposed include familiarity (recognizing individuals they have encountered frequently, often family members), location (associating certain places with kin), and phenotype matching (comparing others' traits to their own or known relatives'). All these methods can help an animal distinguish kin from nonkin.
