Document Summary
Dynamic groups (group composition changes over time) Overlapping generations (relatives but not necessarily in the same place) Lambs lick offspring within a few hours of birth, imprint on odour/taste use chem. Cichlids learn odour of first brood use odour to identify subsequent broods (if first time parents eggs swapped reject subsequent broods) Naked mole rats f tends to mate only with males w/ unfamiliar scent (inbreeding avoidance) Indirect recognition based on context of situation (location/time) Direct recognition individual"s phenotype directly examined and compared to a template. Remember individuals they associated with during a specific time period. Evolves when being born together is reliable cue of kinship (no dispersal/overlap) Prairie voles mate monogamously and pair bond for life, young raised together for extended periods. Use salient aspects of one"s own phenotype or phenotype of known kin and compare to potential kin. Evolves when familiarity not reliable (multiple mating, dispersal, etc) Belding"s squirrels males/females mate with multiple individuals.
