Amazing facts about how animals feel sad for losing their peers

In August of 2018, the press reported images of a female whale carrying a small dead carcass for 17 days. Two years ago, a chimpanzee was seen at the chimpanzee house to house chimpanzees in Zambia, trying to clean the teeth of her adoptive son Thomas after he died in a scene described as funeral rites

Elephants were known to visit the remains of their deceased family members and were raised on their bones and sometimes walked forward and backward as if they were performing religious rituals

Do humans and animals express their grief in the same way?

The importance of our studies is that it helps us understand the evolution of death-related behaviors from their primitive state to what we see in humans today of feelings, rituals, and customs

Like humans, the response of animals to the loss of their peer's variants from one animal to another and from one species to another. Social animals generally exhibit behaviors that may be described as expressions of grief

It is not surprising that dolphins and whales, known to be smart and social, Grazing the dead squadron, either by carrying or dragging it, or by spontaneous behaviors, such as lifting the carcass and dipping it into the water, as if to help breathe, or perhaps circulate and dive

John Gonzalo, of the Ionian project funded by the Tethys Research Institute,
 He had twice seen a group of nasal flask dolphins
Accompanied by a female dolphin carrying her son's body for several days, and once again saw her trying to save a small dolphin who was dying by keeping him floating, and stayed in the place for a while after his death

The dolphins, who carry the carcass of their young people for several days, need time to overcome their sorrows and accept the idea of losing their newborn babies, which was surprising and unexpected, Dr. Gonzalo said. While the dolphins in the second case felt relieved to have the dolphin die so as to exercise its life as usual, instead of carrying the carcass for another week

The carrying of the small carcass may seem strange, but it is very common among primates. Scientists have observed many species of primates monkeys carrying their young babies for weeks or months. In extreme cases, mothers treated their young babies until they were completely engulfed by heat, leaving only a skeleton or a spine

Some primates may express grief over the loss of their peers in other ways, such as taking care of the carcass, cleaning their teeth, touching them gently, and sometimes exhibiting aggressive behaviors such as appealing, trying to hold or even taking care of the hair 

"The monkeys' behaviors, like humans, different according to the personal characteristics and degree of kinship of the Deceased," says King, who has observed the chimpanzees, the monkeys of the bonobos, the gorillas and other primates for years: "I saw some monkeys graze their peers gently and tenderly, but some male chimpanzee sometimes act aggressively

"Death is one of the worst afflictions on social animals," says Edwin van Leuven, of the Max Planck Institute for Psychological Linguistics, which documented the cleaning of chimpanzees to the teeth of her adopted son: When an adult dies, for example, It may help the herd as a whole or lose its young to express social cohesion

"The behaviors associated with the loss of close friends are not innate, but we gain them through the experiences we experience," says Dora Peru of Oxford University. For example, children need years to absorb the idea of death

Gonzalo says that the sadness of the death of the close has evolved in animals and humans as a means of adapting to the idea of leaving irreversibly. Smart animals and humans need time to absorb the idea of separation. In other words, grief is the price we pay for love

It is not surprising that the archaeological sites are full of drawings of the dead, and the various peoples and tribes began countless rituals of death, from funeral to burial, decorated coffins and built pyramids. The Indonesian tribe of Toraja lives with the body for weeks under one roof

"Studying the feelings of sadness in animals not only raises the issue of animal welfare but also highlights the issue of animal rights," says King, "and if we realize how deeply animal feelings are, we may wonder about the existence of zoos and pits around the world. These animals feel like we are sad to lose close friends and loved ones
