Researchers Ponder Why Animals Adopt Other Species’ Orphans

Beliefs about what animals “should do” are often hampered by a lack of common sense reasoning and an outdated evolution theory

At The Conversation, evolutionary anthropologist Isabelle Catherine Winder (pictured) and anatomist Vivien Shaw pose a question, “Animal adoptions make no evolutionary sense, so why do they happen?“ For instance, scientists working with gorillas in Rwanda recently found the gorillas band together to take care of orphans. In these cases, young peers and (surprisingly) dominant adult males can be key to immature orphans’ survival. Perhaps it really does take a village to raise a child. Meanwhile researchers in DR Congo found that bonobos (apes closely related to chimpanzees) go even further, and sometimes adopt babies from a different social group. We even have examples of cross-species adoption, such as the dolphin who adopted and nursed a melon-headed whale, and a group…

Bonobo Chimpanzees Adopt Orphans, a First for Great Apes

But this story is not what it seems. Let’s cut through some pop science assumptions. The real story is an argument that humans are not just animals

There’s been a stir recently among primate zoologists around two female bonobos who adopted infants from outside their group: During observations at the Luo Scientific Reserve in Wamba, Democratic Republic of the Congo, the scientists saw the mother bonobos (Pan paniscus) carrying, grooming, nursing, and sharing food with their adoptees, who were in excellent health and treated well by their new social groups. The team’s analysis of DNA extracted from the infants’ faeces confirmed that the youngsters were genetically unrelated to the groups they lived in. “Bonobo mums open their arms to outsider orphans” at Nature Why do they do it? Various explanations are offered: The researchers suggest, “In both cases, adoptees had no maternal kin-relationship with their adoptive mothers.…
