Another, named Mari, couldn't comfortably complete the tasks because of difficulty breathing through her nose, making sipping juice uncomfortable. A chimp named Pendesa had a cyst on her brain that affected her field of vision. The team recruited 10 adult chimpanzees for the experiments, all housed at the Primate Research Institute in Kyoto, Japan, although three chimps ended up dropping out and being excluded from the final study. The subjects were allowed to sip juice through a nozzle to reduce head movement during the experiments. Chimps were shown sets of images, and eye-tracking equipment monitored their eye movements (a common indicator of attention). The study was conducted using an experimental booth housed in a testing room. The dead chimps in both cases had actually been killed by fellow chimpanzees, and this is just one of a wide range of observed reactions to chimpanzee skeletons.) Advertisement (There were confounding factors, however. A 2020 study reported on two cases of a chimpanzee community clustering around a skeleton, suggesting that perhaps the chimps were drawn to the remains because they still bore some resemblance to a living chimp. For instance, some chimpanzee mothers will carry their dead infants for days or even months. ![]() Numerous studies have been conducted that show chimpanzees' reactions to deceased chimps, such as revisiting corpses and showing signs of mourning. However, the study found no evidence that the elephants could recognize the remains of close kin, concluding that this observed behavior is due simply to their general attraction for elephant remains. It has also been suggested that elephants "visit" the bones of their deceased relatives.Ī 2006 study of African elephants conducted by scientists at the University of Sussex found that the elephants showed more interest in the skulls (or tusks) of their own species than the skulls of other animals (such as a buffalo or rhinoceros). In fact, elephants have been observed showing interest not just in elephant corpses, but in bones and tusks. ![]() They share this attraction to faces with humans, and the recognition of chimp skulls may be a form of face pareidolia (the ability to perceive faces in inanimate objects).Ĭhimpanzees are known to share some unusual traits with elephants, including being capable of recognizing themselves in the mirror and showing interest in injured or deceased members of their own species. Swiss primatologist Christophe Boesch once commented on a picture of a chimpanzee skull, pondering, "What goes on in the chimpanzee's mind when they see such a sight in the forest?" We might not yet be able to suss out what chimps are thinking regarding their own mortality, but they do show a strong preference for the faces and skulls of their fellow chimps, according to a recent paper published in the journal Royal Society Open Science. Goncalves et al., 2022 reader comments 35 "It might take experience to understand that death results in a long-lasting 'cessation of function', which is one of the concepts of death that humans have," Carter said.A. The idea is that the older the primates are, the more likely they have learned that if a baby doesn't move, it is probably dead, in which case it might be easier for them to break the bond with the baby. Taking these findings together, the scientists have drawn up a hypothesis: that primates can learn about death "in similar ways to humans," said the study co-author Alecia Carter, a lecturer in evolutionary anthropology at University College London in a press release seen by Insider. The third was the age of the babies: the younger they were when they died, the longer they were carried.The second was how the babies died: if he or she had been killed by a traumatic event, like a predator attack or an accident, they were less likely to be carried than if they died suddenly by illness or stillbirth.The first was the mothers' age: younger mothers were more likely to carry the dead baby.Account icon An icon in the shape of a person's head and shoulders.
