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. The closest expression chimps have to a smile is a play face.
Grooming, for example, shows affection and respect. And when it's time for a fight, a monkey with whom you've built a friendship is much more likely to fight at your side — or clean your wounds afterward!
Laughter is especially noticeable when they are playing or being tickled. Laughing means “I am having fun” and will prolong playtime. Laughter is often used as a “social lubricant” to make an awkward situation less uncomfortable. This behavior is present in both humans and monkeys.
These findings suggest that relaxed open-mouth display serves important functions regarding submission, reconciliation, affiliation and reassurance in coordinating social interactions within OMUs in golden snub-nosed monkeys.
A new study has revealed that chimpanzees have the same types of smiles as humans when laughing, which suggests these smile types evolved from positive expressions of ancestral apes.
Some scientists suspect spontaneous smiles in these monkeys echo the development of our own expressions. Scientists from the Primate Research Institute at Kyoto University in Japan have observed these spontaneous smiles in Japanese macaques for the first time, according to a new study published in the journal Primates.
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.
Turns out, chimpanzees use hugs and kisses the same way. For most folks, a nice hug and some sympathy can help a bit after we get pushed around. Turns out, chimpanzees use hugs and kisses the same way. And it works.
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.
Spider monkeys embrace to keep the peace
We all do it: Give friends and family a peck on the cheek, a quick hug, or maybe even a nose rub to say hello. It's a way of assuring each other that we have no hostile intent, anthropologists say.
For instance, studies have found evidence that teeth chattering plays a key role in macaque social interactions by signaling fondness or submission, among other things. If playback doesn't begin shortly, try restarting your device.
Often, a monkey will lip smack to a more dominant monkey as a sign of submission. You might also see monkeys lip smacking to one another after having a disagreement as a way of apologizing and making sure all is forgiven. It can also be a sign of affection or contentment.
“You'll often see the male approach the female and sometimes he'll tap her or get in her face to get her attention and he'll make faces such as lip smacking, where it's rapid movement of the lips, or jaw thrusting, where the lower jaw is stuck out and the head is raised.
These studies are often cited as evidence that “monkeys, like humans, are able to use faces to recognize individuals” (e.g., Parr et al., 1999, Pokorny and de Waal, 2009a; see also Leopold & Rhodes, 2010) or, in monkey physiology studies investigating IFR, that “faces are important for primates” (e.g., Chang and Tsao, ...
Many linguists still believe that apes have no real grasp of human language, but are merely imitating their human companions. They insist that while apes may understand individual symbols or words, they do not understand the concepts of syntax, or how words are put together to form a complete idea.
Children and adults alike crave this sweet yellow fruit. Whether you like to peel a banana and eat it fresh or you prefer a banana split with ice cream and other toppings, these tempting treats will tickle your taste buds. Monkeys probably don't know much about nutrition, but they know they love bananas.
While some monkeys are gentle, some are very aggressive. However, even the gentlest monkeys are unpredictable and might turn aggressive on anyone, including the person to whom they are the closest, especially during and after puberty.
It seems intuitive that primates experience sexual pleasure in a similar way to humans [50,51]. Indeed, female orgasms occur in lemurs, marmosets, macaques, and apes [18,28].
In general, no. Humans and other primates rarely overlap in habitat, so judging by the numbers alone there is no attraction.

Macaques
Female macaques are more likely to experience orgasm when mating with a high-ranking male. Researchers believe that macaques have sex for pleasure because their sexual behavior is similar to humans. For example, macaques experience elevated heart rates and vaginal spasms when mating.
Similar same-sex sexual behaviours occur in both male and female macaques. It is thought to be done for pleasure as an erect male mounts and thrusts upon or into another male. Sexual receptivity can also be indicated by red faces and shrieking.
But studies have shown that direct eye contact with macaques can be taken as a sign of aggression or threatening behavior.
Abstract. Nonhuman primates posses a highly developed capacity for face recognition, which resembles the human capacity both cognitively and neurologically.
“Male titi monkeys show jealousy much like humans and will even physically hold their partner back from interacting with a stranger male,” says Bales. The researchers induced a “jealousy condition” in male monkeys by placing them in view of their female partner with a stranger male.
