Abstract:
The chosen study is a 1998-1999 survey of approximately 25 orangutans (Pongo pygmaeus) in the Meratus forest in Borneo. The Meratus forest has had no naturally occurring orangutan population since 1997, and it is a popular location to "reintroduce rehabilitant orangutans and translocate wild individuals (Grundmann, 300)." The initial goal of the project was to investigate newly reintroduced orangutans to determine what skills became underdeveloped due to the animals not needing to use them in captivity. The researchers found that the orangutans could be grouped into three separate classes; the experts, the students, and naïve ones. Experts were animals with forest experience and who had showed the abilities to "gain access to all types of feeding items," (Grundmann, 300), the students were those orangutans that were able to get by in the forest but did not have the skills to enable them to gain access to harder foods, and the naïve ones were those who had been recently reintroduced and were mostly dependent on having food brought to them. After classifying the animals, the authors were able to look at several specific behaviors that the animals either were or were not able to display. The researchers looked at the activity budgets of the orangutans, the ability to build nests, their mastery of arboreal environments, and the ability to share food.
Analysis:
In this study the purpose of the authors was to analyze the behavior of previously captive orangutans in a natural setting along with other orangutans who had been released earlier. More specifically, the authors wanted to know how often and for how long the orangutans rested for, how proficient they were at building and sleeping in nests, ...

The fact that some orangutans use tools and some don't can tell us about the way their societies are set up. The orangutans that use tools are more tolerant towards each other and therefore live in higher density populations, while those who don't use tools and the Bornean orangutans are more independent and less tolerant of others. These findings are in agreement with Grundmann's; both studies show that orangutan behavior is highly tied to its developmental stages.

"Children of the Forest" is a narrative written by Kevin Duffy. This book is a written testament of an anthropologist's everyday dealings with an African tribe by the name of the Mbuti Pygmies. My purpose in this paper is to inform the reader of Kevin Duffy's findings while in the Ituri rainforest. Kevin Duffy is one of the first and only scientists to have ever been in close contact with the Mbuti. If an Mbuti tribesman does not want to be found, they simply won't be. The forest in which the Mbuti reside in are simply too dense and dangerous for humans not familiar with the area to enter.
Every few years, Hollywood releases a new Planet of the Ape movie, which is always a blockbuster hit. Moviegoers flock to see these movies of how apes rise together and how they are actually more intelligent than meets the eye. Most people do not know the premise behind these movies of how smart and closely related apes are to humans. This is because people probably have never taken a physical anthropology class and have not done research on apes –our closet kins. Known for his immense studies in the fields of apes and monkeys, his long term research in the behavior of chimpanzees and mountain gorillas, and his experience in the forests with the apes, the co-director of the Jane Goodall Research Center and writer of our textbook, primatologist
Humans are not the only species with the ability of making tools. Early on in her research, Jane Goodall observed an older male chimp, she called him David Greybeard. Through her observation of David, she witnessed two forms of the use of tools. The first was the use of grass as a tool to extract termites from their mounds. The second was the making of a tool by stripping the leaves off a twig, modifying it for the same purpose. When Louis Leakey heard this, he wrote her “Now we must redefine tool, redefine man, or except chimpanzees as humans” (Goodall, 2002). There is a definite correlation between man and chimps in this respect. Human culture involves learned behaviors through observation, imitation and practice, the use of tools with chimpanzees show the same ability for learned beh...
Although the practice of collecting animals have been present since 2500 B.C (Dunlap and Kellert), efforts to keep animals in a safe and natural habitat have been poorly consummated. Psychological manipulation has consequentially drawn chimpanzees to mental illness, as in the article “How Abnormal Is the Behavior of Captive, Zoo-Living Chimpanzees?” Lucy P. Birkett and Nicholas E. Newton-Fisher wrote, “Many chimpanzees (Pan troglodytes) kept in laboratory housing settings show a variety of serious behavioral abnormalities, such as, repetitive rocking, drinking of urine, or self-mutilation.” Social and maternal separation for the benifit of reasearch are linked to psychological traumatic as well (Dunlap and Kellert). Although through history the service of zoos have been for entertainment, it is a trivial reason for holding chimpanzees in confidment. Subsequently, it is inhumane to take primates from the wild and place them in a zoo, commercial, or laboratory setting, which strips them of their ability to act naturally.

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.
In primates such as chimpanzees it is imperative to look at their culture to understand their intelligence. Culture in this circumstance means a specific set of behaviors obtained through learning in a population/species. Chimpanzee’s intelligence is quite unique how they interact with their environment and use it to their benefit just like humans. They have the ability to overcome the obstacles of everyday life through learning and the ability to use tools to create a better quality of life. The complexity of their intellect is different from any other animal ever seen. A significant part of chimpanzee intelligence that sets them apart from other primates and puts them closer to humans is the way they exhibit social learning within their culture and interactions within their environment.

It has been believed that culture is unique to humans and no other groups of animals have culture, but recent evidence refutes this ideology. Before getting into the meat of the argument, it is important to first address the issues regarding the ambiguity of the term, “culture.” What is culture? Many scientists may argue that culture is the way of life for a group of individuals, this definition includes the values, beliefs and traditions of the group (Sapolsky, 2006). Other scientists may argue that culture is the transmission of habits and information by social means (Sapolsky, 2006). Despite the different specifics of what culture is, almost all scientists would agree that culture is transmitted socially through social learning that promotes the transfer of information between members in a group (Boesch and Tomasello, 1998). Based on these notions of culture, it can be justifiably stated that primates have culture. Primates exhibit food preparation techniques, use of tools, communication skills, and most importantly, behaviors of social learning. An exemplar of primates’ capabilities for culture is Koko, the lowland gorilla. Koko, in captivity, was able to learn American sign language, demonstrate self-awareness and the ability to deceive.
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.
For the purpose of this paper I visited the Los Angeles Zoo, on October 23, 2015. Luckily I was able to visit all of the animals in the short amount of time I had. I primarily stayed at the Gorilla and Chimp exhibit to understand their behaviors and how they act like us.
Apes have over and over again surpassed other primates in comprehension tests carried out in the laboratory. They are capable of reacting to stimuli in an appropriate manner. Researchers have measured intelligence in primates in a number of situations in an effort to determine the level of cognition these primates possess. Russon and Begun, researchers who have explored ape intelligence state, “In the physical domain, great apes do use tools in ways that require their grade of cognition but they devise equally complex manual techniques and solve equally complex spatial problems” (Russon and Begun 2004). Apes have the abilit...
Different anthropologists such as Nowak and Laird (2010), and Butler (2006), recommended that these residents of jungles contain an exclusive background; position, morals and everyday life is entirely through big adjustment. It can be said that the Mbuti people live in their own world. This paper will discuss the kinship system and the social organization of the culture as far as how they practice equal sharing of food after engaging in hunting and gathering. This paper will also discuss how the Mbuti culture uses gender relation to determine their hunting ages.
Great Apes are at the brink of extinction due to deforestation, hunting, and bushmeat trade. Our closest cousins are now viewed as economic commodities rather than valuable agents to the environment and humanity. In order to explore this issue, there must be an examinitation of why primate populations are dwindling, if these populations can replenish themselves, and what measures the international community is taking to alleviate the problem.
