1.The pygmy marmoset is a small New World monkey native to rainforests of the western Amazon Basin in South America. It is notable for being the smallest monkey and one of the smallest primates in the world at just over 100 grams (3.5 oz). It is generally found in evergreen and river edge forests and is a gum-feeding specialist, or a gummivore.
2.The pygmy marmoset can be found in much of the western Amazon Basin, in Brazil, Colombia, Ecuador, Peru, and Bolivia. The western pygmy marmoset occurs in the state of Amazonas, Brazil, eastern Peru, southern Colombia, and north-eastern Ecuador. The eastern pygmy marmoset is also found in Amazonas, but also in Acre, Brazil, eastern Peru, and northern Bolivia. The distribution of both subspecies is

Communication is big part of the social aspects for life as the Pygmy Marmoset. They use their vocal calls to chatter, to tell of danger, to encourage mating, and to encourage their young. They make clicking sounds in addition to loud calls. They can make short calls for those group members close by. They can also make long calls for those that are further away. These Monkeys don’t live in large groups, they will have 12 members at the most. They really do enjoy bonding and spend all their free time with each other. There show a great deal of sadness when one of their members dies. For the most part they are timid and get along with each other well. They can be aggressive with each other if they need to. Yet they will fight to their own death if they have to in order for them to defend themselves and others in the group. Researchers still want to conduct more research in the area of the behavior of the Pygmy Marmoset. However, it is very difficult to do so without upsetting their natural …show more content…
Infant pygmy marmosets, along with their parents, twin, and other siblings, form cooperative care groups. Babbling, or vocalizing, by the infant marmoset is a key part of its relationships with its family members and is a major part of its development. As the infant develops, the babbling gradually changes to resemble and eventually become adult vocalization. There are many similarities between the development of vocalization in infant pygmy marmosets and speech in infant humans. Vocalizing gives the infant advantages such as increased care and allows the entire family to coordinate their activities without seeing each other.These Monkeys don’t live in large groups, they will have 12 members at the most.

Primates housed in organizations like zoos and laboratories have developed catastrophic behavior; due to the lack of their natural habitat and the lose of freedom to pursue their own lives. Chimpanzees have directed themself to attempt abnormal and often revolting behavior. During their life in captivity they exibit biting themselves, drinking urine, eating feces, pating genitals, rocking, plucking hair, and fumpling niples (Birkett and Newton-Fisher). Another factor that gives chimpanzees
Thesis Statement: Despite the rampant protests of animal welfare organizations on encaging primates in zoos since primates typically show abnormal behavior, zoos in the National Capital Region claim that human interaction and enrichment programs help alleviate the stress and trauma primates experience.

Females receive no help from adult males in caring for their young. Instead, a female will have other female "friends" to help carry and watch over the young as the mother forages. These "friends" are usually offspring from previous years, which do not have young of their own. Since the monkey uses all four of its legs when walking and climbing, the new born babies ride on the mother’s back by gripping her fur, when the mother stop, she will hold her baby with both arms.
Chimpanzees portray their emotions through a number of facial expressions and mannerisms. Just like humans, they undergo mood swings, jealous rages, and laughter. For instance, Goodall observed during her research that a male gorilla “would threaten [me] with an upward and backward movement jerk of his head…” Some of their emotions are easy to read, while at other times we have to look at multiple places on their faces to understand their feelings. A chimpanzee also uses its facial expressions and sounds to communicate with each other, such as hoots and yells.
Language is commonly held to be the province of humans, but other inhabitants of earth possess their own forms of communication. Birds, dolphins, and whales are some of those that have a language. Primates also use vocal communication with each other. Their utterances have varied uses and volumes, with each primate’s voice being distinct just as human voices are. These unique calls have given researchers insight into the social workings of primate groups. The very fact that primates have a language offers insight into the evolution of language and calls into question what the term human truly means.
Primates have long been understood to have a distinct connection with other animals of its kind, perhaps one of the reasons why their behavior has been most often than not closely related to how humans interact in social groups. However, between different emerging species, it could be analyzed how competition becomes a vital part of the connection they share between each other. This is the reason why it was easier to preserve species of different kinds of primates even within the same locations of habitat. Cross-breeding was not that common among primates due to being highly territorial in nature. Male primates often direct their groups specifically having a distinct distance from other types of other primates. This is why preserving intact social groups among monkeys have been a distinct characteristic of the animal, giving them a greater chance of propagating and preserving their own groups surviving within a specific habitat. When instances of environmental imbalance occurs, primates often move as groups, hence bringing their whole clan and community along with them as they follow their leaders find viable locations to become their new home.
As stated in the article, “each ape’s social success depends on what other group members are up to, natural selection has favored the capacity for social maneuvers and [superior intelligence]” (2). Natural selection also favors apes because they are not ones to dwell or hold grudges on other apes when they get into feuds. Frans de Waal, a primatologist at the Arnheim Zoo in the Netherlands, shows how natural selection has also promoted the ability to strengthen the relationships of others. In his example, he gives an account of Mama, the most influential female in the colony, who would reconcile other apes after they got into
In "Affectional Response in the Infant Monkey", Harry Harlow demonstrated the significance of affectional needs from caregivers to develop secure attachment and
Chimpanzees (Figure 1) are the closest living relatives to us, and they share 99 percent of our DNA (1). Chimpanzees have distinct group territoriality. Male chimpanzees “patrol” near the boundary between the two ranges, at that time they move very carefully and quietly, and they can cease to listen and observe the range of their neighbors. Patrolling individuals are likely to face cruel and violent attacks, injuries, and even deaths. Intense excitement and aggressive display can occur if the two parties of two communities encounter each other. Usually, the larger group holds its ground, and interaction between different chimpanzees communities may also lead to gang attack. Expanding the community range is necessary to their social organizations, the males cooperation can defend the territory and increase the reproductive rates of the resident females by excluding female and male competitors. Body contact is common in their social life such as grooming (1). Usually, chimpanzees groom each other as a way to show harmony and solidarity in their society (Figure 2). Grooming each other demonstrates the deep bonds and close relationship between them. In addition, they can even hug, hold hands, touch, kiss each other as a way of emotional expression (2).

Chimpanzees are part of the non-human primate group. Though we share a common ancestor, evolution has pushed us in different directions. However this common ancestor causes humans to be curious about these creatures. As discussed in Jane Goodall’s video Among the Wild Chimpanzees we were once considered to be human because of our use of tools but once we observed these non-human primates using tools, this perception was changed forever. The question now at hand is if having the chimpanzees that we study in captivity makes a difference between studying wild chimps. These interesting creatures can be found naturally in the rainforests of Africa.
Their fission-fusion social organization includes small, temporary subgroups that travel and forage independently within their community’s home range5 (Fig.1). In East African chimpanzees, adult females are less gregarious than adult males and represent the dispersing sex2. As mothers, they often spend much of their time accompanied only by their dependent offspring6. Meanwhile, adult males are highly social and philopatric; they live in larger groups and form enduring social bonds with individuals of the same sex7. Chimpanzees have a male-dominated society in which rank is a constant battle; therefore males can strongly profit from coalitions. Cooperating in home range defense activities, hunting, and obtaining access to sexually receptive females have an advantage in terms of maximizing their fitness, including increasing their reproductive success and maintaining their social status2. By contrast, females were found to avoid other females to decrease competition for food and
