Rhesus macaques and their offspring interact in the first month of life in ways much like what humans often do, scientists now suggest. The intense, special exchanges that human mothers share with their newborn infants might have deep roots all the way back in monkeys.
The researchers found that the mothers would gaze intently at their newborns, sometimes even taking their baby's face with their hands and gently pulling it towards them to get an even closer look.
Gentle Moms
And they found that, just like people and chimps, macaques can be very tender. The researchers observed macaque moms gently bouncing their young, holding their heads and trying to attract their gaze. And when the monkey moms made lip smacks, their babies often responded in kind.
Rhesus macaques oogle their babies just like human mothers do. It's a look that's been painted and photographed untold times: a mother gazing deep into her infant's eyes while the two smile and kiss. Psychologists believe this interplay helps a child's emotional and cognitive development.
Oral sex has been observed throughout the animal kingdom, from dolphins to primates.
Macaque monkeys grow up with their mothers and are often not familiar with their fathers. But they can recognise the paternal side of the family even without ever being introduced to them, according to a study published in the journal Current Biology.
The monkeys overwhelmingly chose the cloth mother, with or without food, only visiting the wire mother that had food when needing sustenance. Later in his career, he cultivated infant monkeys in isolation chambers for up to 24 months, from which they emerged intensely disturbed.
Natural selection has meant that animal mothers reject the weaker offspring to prevent predation by other species and give longevity to their own, bolstering generations of animals to come. In large, wild mammals, litters are a lot smaller than in domestic animals like cats and dogs.
These monkeys live in monogamous family groups that consist of the mother, father and offspring. The father is the main caretaker for the infants. He brings the infant to her mother to nurse. Infant monkeys are weaned at five months old.
Most cases of such behavior have been attributed to the resource competition hypothesis, in which females can gain more access to resources for herself and for her young by killing unrelated infants.
Not only do baby monkeys cry and scream much like human babies do, but their mothers face similar consequences from those around them. Studies have shown that when monkey infants cry and aren't hushed by their mothers, other monkeys in the vicinity feel free to express their displeasure.
For a species without pair-bonds where it was assumed fathers didn't know which infants were their own, this is an important finding.” Male chimpanzees have paternal recognition and invest in their offspring, not just on future mating. The researchers also found males spend time grooming and caring for their offspring.
Harlow (1958 wanted to study the mechanisms by which newborn rhesus monkeys bond with their mothers. These infants were highly dependent on their mothers for nutrition, protection, comfort, and socialization.
How long a primate should stay with its mother. In order to learn vital “life skills” a primate should stay with its mother through the birth and rearing of a sibling, generally until sexual maturity. For example sexual maturity does not occur in capuchin monkeys until they're about over four years of age.
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!
Something About Scents
Scent glands are generally found in the anogenital area, chest and armpits. They secrete a semi-liquid collection of chemicals. A monkey seen sniffing another's butt is simply gathering information from these glands at the base of the tail.
"Unlike most parents in the United States today, wild monkey mothers have the luxury of being able to feed on demand, carry their babies all the time, sleep with their babies and be responsive rather than doting," says Smith.
However, there is no evidence that any non-human primates are aware of mortality. KEY WORDS: death.
Among monkeys and other primates, males typically bully females around. But when males outnumber females, surprisingly females often prove the dominant sex. These new findings could also hold true with humans, researchers said.
In contrast, monkeys raised by wire mesh surrogates did not retreat to their mothers when scared. Instead, they threw themselves on the floor, clutched themselves, rocked back and forth, and screamed in terror.

“Small-bodied and vulnerable adolescent female Japanese macaques may prefer to engage in relatively safer sexual interactions with female monkey sexual partners in lieu of riskier sexual interactions with more aggressive male mates,” Gunst-Leca says, explaining that sometimes humping other animals is safer than hooking ...
Shattering the long-held belief that humans are the only animals on earth to come to one another's aid during the birthing process, researchers in China have captured the first photographic evidence that monkeys too might sometimes help a mother deliver her baby.
Monogamy is rare in monkeys and primates. Within monkeys an example of a species that tend to be monogamous can be found in the Azara's owl monkeys. Only gibbons are monogamous within apes. Gibbons are the closest species to humans that are monogamous.
