Orphaned bonobos in a sanctuary in Africa have overcome trauma to develop social skills and empathy, new research has shown.
Bonobos have a matriarchal social structure, and maternal loss in primates can have both immediate as well as lasting detrimental effects.
The researchers studied rescued bonobos living at the Lola ya Bonobo Sanctuary in the Democratic Republic of Congo, Africa.
Behavior such as social skills, aggression and empathy were observed among the orphaned bonobos who had not had a role model.
The study showed that the orphaned bonobos did have reduced social skills, but they still demonstrated a degree of typical behaviors for their species, gender and age.
Orphaned bonobos exhibited decreased affiliative tendencies yet showed social functioning ranging within patterns of their mother-reared peers.
The researchers conclude that rehabilitation centers and sanctuaries are important to protect this endangered species, and to better understand the healthy social development of bonobos.
Bonobos are closely related to chimpanzees and the closest surviving relatives to humans, and are capable of altruism, compassion, empathy, kindness, patience and sensitivity.
Bonobos are listed as endangered due to habitat loss and poaching for meat and pets.
The results of the study show that orphaned bonobos are able to overcome trauma and develop social skills and empathy typical of those who do have mothers.
