Bonobos Adopt Infants from Other Groups

A First for the Species

Scientists Discover Unprecedented Behavior

In 2021, scientists made a groundbreaking discovery, documenting the first case of wild female bonobos adopting infants from other groups. This remarkable behavior was observed in two female bonobos, Rose and Bonny, who adopted baby bonobos named Rubin and Jaxon, respectively.

The discovery was made in the Kokolopori Bonobo Reserve in the Democratic Republic of Congo. Scientists had been observing the behavior of bonobos in the reserve for years, but had never witnessed adoption of infants from outside their own group.

The adoption of Rubin and Jaxon is particularly significant because bonobos are known for their close-knit social bonds. Bonobo groups typically consist of related individuals, and adoption of infants from outside the group is rare.

The scientists believe that the adoption of Rubin and Jaxon may have been motivated by the infants' vulnerability. Both infants were orphaned when their mothers died. Rose and Bonny may have adopted the infants out of a sense of compassion or a desire to provide them with protection.

The discovery of infant adoption among bonobos is a significant finding that sheds new light on the social behavior of this endangered species. It suggests that bonobos may be more flexible and adaptable than previously thought, and that they are capable of forming strong bonds with individuals outside their own group.
