 For example, in one study, Mateo and Johnston had golden hamsters reared with only non-kin then later had them differentiate between odors of related and non-related individuals without any postnatal encounters with kin.The hamsters were able to discriminate between the odors, demonstrating the use of their own phenotype for the purpose of kin recognition.This study also provides an example of a species utilizing chemical cues for kin recognition.
