This is not the first time that primates have been observed to pay special attention to a deceased member of their group. In April last year similar behaviors were observed by a chimpanzee mother in Bossou, Guinea who ended up carrying her infant’s body for a total of 27 days. The mother, Jire, regularly groomed and slept next to her infant’s body and showed distress whenever they became separated. In 2000 a chimpanzee mother in the Mahale Mountains of Tanzania carried her infants body for nearly four months and individuals throughout the community were heard making distinctive vocalizations that the researchers had come to associate with fear and agitation. Other cases have been observed in the mountain gorillas of Rwanda, baboons of Ethiopia, macaques in Japan, and ring-tailed lemurs of Madagascar.
