"Jealousy’s proposed function in protecting valuable bonds from external social threats was the impetus for the present study’s emphasis on how reactions to social closeness between other groupmates varied according to relationship quality, further premised on a social context that might threaten long-established bonds (i.e., introductions). The extent to which agonism and interventions towards others’ affiliation actually succeeded in preserving valuable social bonds (not to mention disrupting the real-time interaction) remains open to investigation, and it is worth considering the additional possibility that jealous behaviors might be maladaptive in certain social contexts, particularly when dispersal is limited by captivity."
