Behavioral Comparisons Between Modern Humans and Primates

Monkeys and humans have been compared for years, we have all heard the expression “Monkey see, Monkey do”. Analyzing individual primates at the Santa Ana Zoo was quite an experience because when I use to hear monkeys I use to only picture one certain appearance and that was a brown monkey with a light brown face, and a long tail. Moneys are not just monkeys, humans aren’t just humans, and apes aren’t just apes they are all primates which is a mammal that has certain characteristics such as: flexible fingers and toes, opposable thumbs, flatter face than other mammals, have eyes that face forward and spaced close together, large and complex cerebrum, and they are also social

Primates are one of the most interesting mammals on earth, not only because of their complex social structures, but because they hold so many similar characteristics to humans. Primates are often cited as our closest living relatives and on two separate occasions I observed four separate species of primates at the San Diego Zoo that can justify their use of their physical characteristics and behaviors that may be similar as well as different to the other primates and ours.

Primatology is the scientific study of non-human primate behaviors among wild apes, monkeys and other related animals in natural settings or in laboratories by conducting lab experiments and studies on captive primates. A person who studies primatology is a primatologist. There are many reasons for studying primates, but possibly the most significant reason is to learn about the origins of humans. When studying primatology, one can easily observe the behavioral similarities primates share with humans, and probably begin to understand how humans got to where they are today. The reason anthropology studies primates over any other animal is because primates are the closest living relatives to humans. One primatologist, who significantly surpassed many others in her field, was Jane Goodall. Jane Goodall studied the behaviors of primates and other animals as well, but she specifically studied chimpanzees. Goodall in her book, In the Shadows of Man, shared her three groundbreaking discoveries she achieved through her extensive observations and research. Goodall’s three major discoveries were the complex social system chimps had lived, the hunting and meat consumption process and the usage of tools. Goodall’s research lead to massive evolution in primatology because her research was the starting point that allowed other primatologist to conduct other important researches on chimpanzees and other primates. They managed to study primates in a

-The bonobo is the most recently discovered great ape in modern times.  It was revealed in 1929 by German anatomist Ernest Schwarz that a skull once thought belonging to a juvenile chimpanzee was in fact a new subspecies of chimpanzee known now as the Pan paniscus, or bonobo. (Waal 6)  During the Pleistocene epoch approximately 1.5 million years ago, the Congo River was formed in what is now the Democratic Republic of the Congo. (San Diego Zoo 2)  The river geographically segregated groups and individual chimpanzees south of the river resulting in these chimps being reproductively isolated.  Allopatric speciation took place as a response to new

Within this essay, we will study more in depth the behavioral as well as physical traits of two primates at a zoo from their interaction with their peers to their place in the group. This observation would enable us to further understand the possible existing correlation between humans and primates. First, I studied a female chimpanzee with her baby, and then, a dominant male gorilla, in San Francisco Zoo at about noon, on May 23, 2015, for an hour each. Even though they share some similarities such as having a large brain, living for a long time, and being bored in their enclosure, they are still different; when gorillas are the largest, chimpanzees are the smartest. In fact, chimps use tools to catch food, they would not be able to reach

Isbell and Wright’s articles both focus on monkey species and their native environments, Africa for Isbell’s (1994) vervet Old World monkey and South America, Peru area, for Wright’s (1994) owl and titis monkeys. The articles main focus is the relationship between these monkeys and their natural predators. Focusing on how the predator aspect of their lives is determined by their environment and adaptations they make to ensure survival. Isbell’s Vervets Year of Doom focuses more on the adaptations that was forced upon the vervets’ because of their changing environment, the death of fever trees. While Wright’s Night Watch on the Amazon focusses more on how the primates way of life affects their relationship with predators and the likelihood of attacks. Both articles have similar aspects however the species way of life, specifically their environment and sleep schedule, are quite different as well as the authors way of observing and studying the primates within their habitats.

I have really enjoyed learning in this class and glad I took it because I found it to be very interesting. From learning all these different types of primates, from non-human to human primates, to even developing a better understanding of the evolution of primates and primate behavior. For my final paper, I will be going over and portraying the behavior of non-human primate and human primate. I will be comparing the primates behavior seen over the movies and literatures that we were assigned, to the understandings of evolution. Being able to learn and compare the behavior of non-human primate and the behavior of human primate, it can help further one understandings of how we are similar in physical and biological structures. According to the Wikipedia, “The primate lineage is thought to go back at least 65 million years ago”. (Wikipedia) With this one could say that the evolution of primates have been evolving for quite a while now, and even if we do not look like a non human primate we are similar than we think. The reading materials and the movies we had to watch for this class displayed the behaviors of non-human primate and human primate, some how differed. There are many question about evolution, and to how we were created? are there other reasons deeper than evolution? How much can we learn about evolution by just comparing the different behavior of the primates?

Orangutans (Figure 3) are our first cousins since they share 97 percent of our genetic material. Contrary to other apes, orangutans are semi solitary which is unique in its social organization (3). Adult males which are the most solitary, and they associate with only their current, former, and potential consorts. For the semi-solitary orangutans, the only playmate is its mother. Even female adults are more social than male ones, rarely they groom, touch, hold hands, chase, or fight. On rare occasions, female adults may groom; however, it lasts only few seconds. Sometimes, female adults meet and travel with one another to express the close relationship. The long call by a male orangutan expresses an alert to others about his presence. Usually, other orangutans only react if the call is close by or aggressive towards them. Male orangutan can use vocalization to express that he is angry and frustrated, and that call signals a threat to another male (3). Female orangutans also produce vocalization when they get upset by the presence of another male.

For the primate observation project I went to the Santa Barbara zoo to observe and contrast different types of primates. I observed one species of an old world monkey, which was a gorilla and two different species of new world monkeys, which were the Bolivian Grey Titi Monkey and also the Golden Lion Tamerin.

There are many similarities and differences in primate species.The ones I chose to focus on today was the Philippine tarsier, Mandrill and the gibbon. What made me choose these non- human primates so interesting was the uniqueness and appearance of each primate. I plan to explain the similarities of their teeth structure and purposes and the similarities of their diet and feeding and also the differences of their behaviors.

During my research of Orangutans and Mandrills I observed them in captivity at the San Diego Zoo. My observations included a 20 minute observation of each primate as it cohabitated with other Primates and with other members of its own species. My findings will support the research of Orangutans and Mandrills through firsthand observations.

To better define and understand primates, it is important to breakdown the primate order. Primates can be broken into two suborders: Prosimians and Anthropoids. Prosimians are considered the

For the Orangutan in the zoo each enclosure they had a total of three orangutan in each pen, most were all adults, except one which was a young juvenile. As well as it is appear to be that none of these orangutan are a part of a subgroup because some, if not all isolated themselves from others. In which is very common according to Lang C. (2005), "Adult males and independent adolescents of both sexes range alone while adult females range with their dependent and weaned offspring" (Primate Factsheet pongo, para. 1). So the zoo's orangutan act very similar to the wild ones. Next the differences is how are they physically built between in each others. For the orangutan, if they are standing they are about 5 feet tall, however including arm and leg span due to how they are built to climb and swing to places their body size will be seven feet tall. Another difference was that they had no tail due to they ancestors evolution to who they are now, which remove the chance of having the ability to have a prehensile tail in the process. The last physically difference is their hands. They have all fingers and thumbs, but they don't use their thumbs to grab; they use mostly their fingers to grasp objects. Which make them who they are

Last week I had the opportunity to visit the Los Angeles zoo on a beautiful, sunny Thursday (October 19th). Although I arrived off schedule which left a minimal amount of time to observe primates, I managed my time well. After being told that the larger animals get put away earlier, I figured my first stop would be at an ape enclosure. The ape I chose to see that day was the gorilla. The time that I began my observation was at approximately 3:05. At that time only one ape was quite visible and he was sitting at the front making eye contact with me making it seem as if he is HABITUATED. Next, post gorilla watching, I had the chance to take a gander at the ring railed lemurs at 3:40. These prosimians all had their own personalities which interested me deeply. Lastly, and certainly not least on my journey through the LA zoo, I had the chance of looking at the mandrills which were once classified as baboons. Considering that two baby mandrills were present and only a month old, this was my favorite exhibit to see because of their high energy and randomness of actions.
