In a food-sharing experiment, bonobo sharing behavior remained similar between juveniles (6.83 of 9 trials) and adults (6.33 of 9 trials), unlike chimpanzees.

Confirmed by multiple independent sources including peer-reviewed studies (Current Biology, ScienceDirect) and a research summary from Duke University's evolutionary anthropology department, all consistent with the specific trial data cited.
