The orangutans (pongo borneo) are mammals from primate group, considered to be very close relatives to humans, chimpanzees and gorillas. They are species found only in Asia, specifically rainforests of Sumatra and Borneo. Orangutans are 400 000 year old species and are considered to be one of the oldest, still existant primate species. One of the characteristics of these apes is their reddidh-brown fur, and bulky black skin.
Physical aspects
Orangutans have an enormous arm span. A male can stretch his arms 2 meters from fingertip to fingertip which is a reach longer than his standing height of about 1.5 meters. When orangutans do stand, their hands nearly touch the ground. Other physical aspects include their large strong bodies, thick neck, short legs, no tail and as mentioned before reddish-brownish fur covering the body. By their gender, (except the obvious difference) these apes do vary phisically in their weight and height,

This has been caused primarily by human activity (intense legal logging, illegal logging, conversion of forest to palm oil, mining, clearing forest for settlements, and road construction) and also by the El Nino weather phenomena. Orangutans are also occasionally hunted and eaten by some of the people of Borneo as well as migrant loggers and plantation workers. It is also not uncommon for them to be caught by circuses where they are displayed as performers, as cause of their great intelligence.
Conclusion
Orangutans are represented as lazy, boring species, but after finding out all this information, my opinion has changed and now I find them quite interesting because of their intelligence. I really hope oragutans do not get extinct as world would lose a species different from any other primates as a result of humanity being itself, selfish and not caring for
The primate freedom organization protects primates from inhuman experimentation in hopes to stop animal experimentation. They also donate Primate Freedom Tags and provide research to other organizations. Finally, they write articles for campus publications, foster community, and campus-based Primate Freedom Projects, and work to connect all primate freedom efforts
The theories of early primate evolution are Arboreal, visual predation, angiosperm hypothesis. The Arboreal theory explains primates unique traits in adaption in trees while visual predation details the
These lines of primates that were being forced out of their homes and made to relocate eventually became virtually extinct because of the overall increase in temperature.
Due to the intellectual level of primates there parenting skills differ from other mammals. Primates birth fewer off spring than other mammals because there births are spaced out over time to account for teaching and nurturing the newborns. Primates tend to take much better care of there infants with mothering qualities due to there intelligence which is far different than other mammals who sometimes give birth and leave there young. Primates care for there offspring much more than other mammals and do things that more closely resemble the care humans have when it comes to parenting as oppose to animals like dolphins and other mammals. There are six types of social groups which primates follow.
The physical nature of a primate body as wells as its movement is a unique factor in the animal kingdom. There has been continuous change through locomotion and body configuration throughout each grades of primate evolution. In this essay I will be discussing the modifications in time as well as theories in each grade of primate. This research paper will try to elaborate on the evolutionary modifications and some of the theories that have been proposed for these changes throughout our and other primate evolution. With time primates development was due to environmental changes.
The bonobo and the chimpanzee are physiologically very similar, so much so that bonobos were considered a subspecies of the chimpanzee for quite a while before they were destinguished as their own species. While the chimp is slightly larger, they are relativaly the same. They both are terrestrial and arboreal at times; The chimpanzee makes nests in trees at night. Though they look fairly similar, the bonobo and the chimpanzees vairy wildly when it comes to social and behavioural traits. Chimpanzees live in large groups of many male and female individuals.
Climate change influenced nonhuman primate evolution by forcing the evolution of species and creating new environments that allowed for primates to live. "A rapid temperature increase around 55 mya ... led to an expansion of evergreen tropical forests, the environment that made possible many mammalian groups, including primates." (pg. 260). As rapid temperature increase created new environments a rapid cooling in the beginning of the Oligocene limited the range of habitats greatly. Due to this reduction a majority of the primates during this time lived around the fayum region in northeast Africa.
Humans have been examining and studying non-human primates for ages in an attempt to further understand the reasoning behind human behavior and base instinct. While it would be ideal to study non-human primates in the wild, away from possible interference from human civilization, that is often not the case, especially for students, and in this case the non-human primates have been observed within captivity. Specifically, the species observed were the Tufted Capuchin monkey (Cebus apella) and the common squirrel monkey (Saimiri sciureus) at the Living Links to Human Evolution Research Centre in Edinburgh Zoo. The tufted capuchin monkey is most commonly found within the neotropical regions of South America including: Columbia, Ecuador, Peru, Brazil, Suriname,
Through history there has been evidence to help support the claim that climate change has influenced the evolution of primates. Scientific evidence has proven that during certain climate spikes such as the swamp age, apes in the given territories that encompassed Africa led a migration to the Asia and Europe territories. The same climate changes that was responsible for the creation of the Swiss Alpes and other phenomena, has been associated with the adaptation, extinction, and migration. As weather changed in certain areas, the land became more dry making it harder to obtain and hunt food. Climate change, in theory, led to the extinction of the Sivapithecids apes because of the inability that the species has to obtaining food.
Not everyone agrees with the GAP’s but some people do have special obligations for the great apes. Great apes are our closest relatives. Former animal researcher Roscoe Barlett researches about primates and wants to extend the rights for the animals. Kevin Martin,
Studying captive primates can help us learn not only how they behave, but also how they are similar or different to each other and humans as well as give us insight into the effects of captivity. This paper will be describing, comparing, and contrasting the behavior of two species of captive primates at the Alexandria Zoo, golden lion tamarins and howler monkeys, as well as discussing the possible effects captivity could have had on them. This paper will also discuss any human-like behaviors observed in the two primate species and what we as humans could learn about our own behavior by studying primates. The two primates I observed were 1 of 3 golden lion tamarins (Leontopithecus rosalia) all of unknown gender and a solitary female howler
An example is they consume fruits with seeds. Gorillas are the third closest living relatives. The gorillas live in Africa near the equator. Gorillas are the largest primates alive today. They're heavily built animals with large chests and shoulders, big hands and their upper arms are longer than their forearms.
Howler monkeys are one of the largest New World monkeys found in South and Central America, more specifically found in tropical forests of eastern Bolivia, northern Argentina, southern Brazil, and Paraguay. They live in large social groups that contains all of the family members such as parents, siblings, aunts and other relatives. They form a family of 8 or more members that stay and survive together. A unique fact about their group structure is that some of the male and female will leave the group they were born in and move on to join a total new group, with the majority of their lives growing up is spent in groups they weren’t born in or related to. Male and female howler monkeys are quite different in their appearance.
Have you ever thought about which animals are near extinction or endangerment ? Have you looked them up? How many are left? Which ones have been removed? Do you know why they are going endangered?
Primates began to walk on the earth about 50-55 millions years ago, seeing drastically different terrain than what we experience today. During this time primates were not forced to deal with the harsh demands we face in the world currently, thus drawing our first difference. The first primates lived on an earth where the need to walk on two feet was unnecessary. Clearly giving the biggest reason as to why primates and humans share little in common. For today humans walk solely on two feet and adapt to the changing environmentally more quickly than primates.
