Altruism in Forest Chimpanzees: The Case of Adoption
Observed adoptions of orphaned youngsters by group members in Taï forest chimpanzees reveal that, under the appropriate socio-ecologic conditions, chimpanzees do care for the welfare of other unrelated group members and that altruism is more extensive in wild populations than was suggested by captive studies.

Adoption of a Wild orphaned ringtailed lemur infant by natal group members: Adaptive explanations
For the subadult male and adult female caregivers, kin selection can be suggested, as the infant was related to all females and immature animals in the group, and adult males may have exhibited caregiving behaviors as a strategy related to affiliation with adult females which could lead to potential mating and reproductive success.
