In a food-sharing experiment, bonobo sharing behavior remained similar from juveniles (6.83 out of 9 trials) to adults (6.33 out of 9 trials), unlike chimpanzees.
Notes on verification
Confirmed by peer-reviewed study in Current Biology (2010) and corroborating summaries from Duke and Harvard sources, showing bonobos maintain juvenile-level prosocial food sharing into adulthood unlike chimpanzees.
