Monkeys have tear ducts, but these are just to keep the eye from drying out; weeping and shedding tears is not a behavior monkeys perform when sad. However, monkeys are very social creatures and do have vocalizations and facial expressions of their own to express sadness and anguish to each other.
Monkeys, apes and other simians have nothing quite like our tears. They have tear ducts to help keep their eyes lubricated and clean. But they don't drain when they're sad. Chimps will scrunch up their faces and make noise when they're in distress, but they don't connect the tears and the wailing.
Are human beings the only animals that produce tears when they cry? If you define crying as expressing emotion, such as grief or joy, then the answer is yes. Animals do create tears, but only to lubricate their eyes, says Bryan Amaral, senior curator of the Smithsonian's National Zoo.
Empathy: Chimpanzees are capable of feeling a wide range of emotions, including joy, happiness and empathy. They look out for one another and often provide help when needed. For example, both male and female adults have been observed adopting orphaned chimps in the wild and at the Tchimpounga sanctuary.
Gorillas may cry out as vocalizations, but they actually don't produce tears like humans do when we cry. Gorillas produce tears in order to lubricate their eyes, but tear production as a form of distress is completely unique to humans within the primate species!
Baby animals that are separated from their mothers sound a cry, but humans are the only ones who shed tears. (Stone/ Getty) Pet owners often claim their dogs cry. Darwin thought monkeys and elephants wept. But modern scientists believe the only animal to really break down in tears is us.
Elephants do grieve, and they are one of the few animals who are similar to humans in mourning patterns. Believe it or not, elephants cry.
Sadly, many tourists misread wild monkey facial expressions. A wild monkey which appears to be smiling, pouting its lips or baring its teeth is not friendly. Many tourists mistakenly think that the monkey is smiling or blowing a kiss. Nothing could be further from the truth as these are all signs of aggression.
Myth: Chimps can smile like humans do.
Chimps make this expression when they are afraid, unsure, stressed, or wanting to appear submissive to a more dominant troop member.
It is interesting to note that some adult wild-born macaques spontaneously exhibit depressive behaviors even though they have not been subjected to experimentally induced early-life stress (Camus et al. 2014; Shively et al. 1997; Willard and Shively 2012).
Summary: When someone feigns sadness they 'cry crocodile tears,' a phrase that comes from an old myth that the animals cry while eating. Now, a researcher has concluded that crocodiles really do bawl while banqueting – but for physiological reasons rather than rascally reptilian remorse.
Autism is a neurodevelopment condition found in humans, and some of the diagnostic criteria, such as a delay in language development, can't apply in a straightforward way to animals. That said, some animals do display autistic-like traits, such as a tendency toward repetitive behaviour or atypical social habits.
Bonobos Cry Like Human Babies When Attacked to Get Comforted: Scientists. Bonobos produce high-pitched "baby-like" cries when they are attacked - to attract comfort from others, reveals new research. The displays of distress are strategic, increasing their chances of consolation from other apes, say scientists.
A study on New World monkeys observed that not only do primates grieve, some have even shown signs of caring for dying members of their troop.
There's no question that they can experience pain and psychological distress as a result of experimental procedures and from the way they are bred, transported or housed. The capture of wild primates for use in breeding colonies and for experiments in some countries also causes very significant suffering.
About 82 percent of the time, the apes laughed spontaneously, producing a panting-like sound when a playmate surprised them by, for example, throwing a stick; 18 percent of the time, the chimps produced short chuckles in response to their playmate's laughter.
Researchers investigated jealousy in male titi monkeys – a monogamous primate that shows jealousy much like humans. Jealousy leads to increased brain activity in areas associated with social pain and pair bonding in monogamous monkeys, finds a study in Frontiers in Ecology and Evolution.
Capuchin monkeys are known for their ability to recognize when they're being treated inequitably, but it now appears the primates can even spot unfairness in situations that don't involve themselves.
Abstract. Nonhuman primates posses a highly developed capacity for face recognition, which resembles the human capacity both cognitively and neurologically.
In most primates, eye contact is an implicit signal of threat, and often connotes social status and imminent physical aggression. However, in humans and some of the gregarious nonhuman primates, eye contact is tolerated more and may be used to communicate other emotional and mental states.
Monkeys to feel regret and learn from their mistakes just like humans, according to a new study.
Primatologists offer rich anecdotes of chimpanzee behavior to persuade us that these animals may possess rules, but honesty forces them to admit that they have never seen a guilty chimpanzee. And they will not, for guilt is not a possible state for chimpanzees.
When a family member, human or animal, is lost, becomes ill, or dies, it affects the whole family. Effectively supporting the grief process in the surviving pack members allows the pack to move forward. Animals display grief in a manner similar to humans. Aspects of their personality may change for a period time.
Elephants Grieve and Understand Death
Elephants are the most well-known animal species that mourn their dead. They often visit the carcass of a fallen loved one and keep returning even when the body has decomposed, and all that is left are sun-bleached bones.
Asian elephants, like their African cousins, seem to mourn their dead, sometimes even carrying their lost infants in their trunks for days or weeks, new research finds. Whether elephants understand death in the same way humans do is unknown — and probably unknowable.
