Bonobos (Pan paniscus), along with chimpanzees, are humans nearest evolutionary relatives. The diet is supplemented by invertebrates such as caterpillars and earthworms. Furthermore, the phenomena of infanticide, cannibalism, and lethal invasion seen among chimps have never been observed among bonobos. Also, the introduction of immature or mature bonobos to an unfamiliar group in zoos and sanctuaries usually proceeds relatively smoothly compared to that of chimpanzees60,61.

We conducted daily observations from approximately 05:50 to 12:00, with a rough schedule of 4-day working and 1-day off, observing bonobos on a total of 204 days, amounting to ~1159 h of observation time. The adoptive mothers provided various maternal care to the adoptees, such as transportation, grooming, nursing, and nesting together. She groomed her biological offspring more frequently than the adoptee, and her older biological offspring showed signs of distress when her mother stopped carrying her due to the presence of the adoptee, suggesting there may have been some conflict. We observed Marie sharing food with Flora, Marina and Margaux simultaneously one time (fruit of Anonidiwn manni), with Flora and Margaux simultaneously three times (fruit of Treulia africana in two cases and young leaves of Leonardoxa romii in the other case), with Flora alone once (fruit of A. manni) and with Margaux alone once (fruit of Musanga cecropioides). Despite this, in case 1 we did not observe affiliative, sexual, or aggressive interactions between the biological mother and individuals in the adoptive group. But instead, maybe the ape took the mongoose pup for dinner after killing its mother.
