I will consider support for the dwarfing hypothesis in New World monkeys. Since evolution has shown to result in a general increase in body size, the case of reduced body size in the New World primates is quite unusual. To explain the phenomenon, the dwarfing hypothesis has been proposed (Martin, 1992).…
The sciencemag.com article “Anti-Alzheimer’s Gene may have Led to the Rise of Grandparents” by Kelli Whitlock Burton talks about the how the protective variant of the CD33 gene may explain why humans have grandmothers that help with child rearing. The article explains the “grandmother hypothesis” that says humans live such long and healthy lives even after they are no longer able to reproduce because they help with child rearing. The CD33 gene plays a big role in Alzheimer’s disease and scientists Ajit Varki and Pascal Gagneux discovered that there are two variants of it: a protective allele and a damaging one.…
Either the Heron or Hawk and fish populations in the salt water marshes are a prime example of a predator-prey relationship; the heron finds its prey by walking or “waddling” through the shallow waters of the marsh and catching fish by striking them with the birds long neck and beak, swallowing the fish whole; and the Hawk with its powerful wings flies down and grabs the fish right out of the water (Also helping to control the area’s fish population.)…
Summary Response In the article “Of Primates and Personhood” written by Ed Yong, demonstrates major developments between primatologist, biologists, and ethicists around the world. These major developments are a pending spanish law that would grant unprecedented protection toward great apes; Also, a recent extension to a swiss law that protects the dignity of organisms, and to redefine the meaning of human rights, and indeed whether such rights are the exclusive domain of humans. Furthermore, the Great Ape Project (GAP) has been established (1993). Not everyone had been comfortable with the GAP’s project, says Yong;…
Primate socio-ecology varies and has different determinants that decide many different characteristics. As a virtual paleontologist, we discovered two different sites and skeletal remains in Kenya and deductively reasoned their mating habits, group size, and several other characteristics about the Praeanthropus dimorphicus and the Praeanthropus monomorphicus with what I know about primate socio-ecology. Based on my prior knowledge, logic, and reasoning, by looking at skeletal remains we are able to deduce many different features included in primate socio-ecology for these two different species that include: group size, diet, mating system, habitat, and finally ranging behavior and territoriality.…
My initial thoughts about going having to go to the zoo for this project was that it was going to be challenging yet fun, Challenging in the sense that with my post traumatic stress disorder from the military because I have trouble being around crowds of people which is why I supposed that is why I chose to go to the Santa Ana zoo since I knew that there would be less people there, Fun in the sense that I have not been to a zoo since I was a little kid which made me excited to not only see the primate exhibit for this project but to also check out some of the other animals that were at the zoo.…
The male common chimp is up to 1.7 metres (5.6 ft) high when standing, and weighs as much as 70 kilograms (150 lb); the female is somewhat smaller. The common chimp’s long arms, when extended, have a span one and a half times as long as the body’s height and a chimpanzee's arms are longer than its legs.[7] The bonobo is a little shorter and thinner than the common chimpanzee but has longer limbs. Both species use their long, powerful arms for climbing in trees. On the ground, chimpanzees usually walk on all fours using their knuckles for support with their hands clenched, a form of locomotion called knuckle-walking. Chimpanzee feet are better suited for walking than are those of the orangutan because the chimp’s soles are broader and the toes shorter. Both the common chimpanzee and bonobo can walk upright on two legs when carrying objects with their hands and arms. The Bonobo has proportionately longer upper limbs and tends to walk upright more often than the Common Chimpanzee. The coat is dark; the face, fingers, palms of the hands, and soles of the feet are hairless; and the chimp has no tail. The exposed skin of the face, hands and feet varies from pink to very dark in both species, but is generally lighter in younger individuals, darkening as maturity is reached. A University of Chicago Medical Centre study has found significant genetic differences between chimpanzee populations.[8] A bony shelf over the eyes gives the forehead a receding appearance, and the nose is flat. Although the jaws protrude, the lips are thrust out only when a chimp pouts. The brain of a chimpanzee is about half the size of the human brain.[9]…
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.…
In the film, Among the Wild Chimpanzees, the National Geographic Digital Media interprets Jane Goodall’s study of chimpanzees in Gombe, Africa. In the 1960s, the chimpanzees had a vicious reputation by rumors. However, Goodall had an interest in the wild and went to observe the chimpanzees and their uncanny resemblance to humans. To gain the trust of the chimpanzees, she intentionally goes on top of a peak to appear less of a threat. Her and her partner filmed the chimpanzees using a camouflage. Moreover, the chimpanzees are nomadic and their diet is particularly meat-free. When they find a place to stay, it takes minutes to create a bed using branches. As for familial life, the mother and child are often seen together while the father does…
According to an article by the Wildlife Waystation, Capuchin monkeys have a “dark-colored cap of fur on their heads” and “dark sideburns”. Due to these physical characteristics, these monkeys were named after the monks in the “Order of Capuchin Friars” which were compared to their headdresses. Most of the Capuchins weight ranging from three to nine pounds and are thirteen to twenty -two inches tall. In the wild life, Capuchins are known to live from ten to twenty-five years. A capuchin’s habitat is mostly on top of the trees and they can be found in rainforests or low lands in islands in the South America and countries such as Brazil, Argentina, and Columbia. The long, prehensile of the Capuchins allows them to be able to grasp onto the tree branches and swing themselves from tree to tree with no difficulty. Capuchins also have opposable thumbs that help them grab onto their food and use their tools while they hunt. The geographic distribution of the Capuchins is mainly in the South America continent.…
In a world where time travel is not possible there is no way to observe evolution directly as each species changes and diversifies . In order to better understand the process and its effect on species we must observe them and their ancestors , by observing we can find similarities between these animals as well as the differences and how each one has adapted differently to its own environment. By observing Chimpanzees and the Crested Capuchin monkey, both of which had an infant and mother pair it was easy to see the differences as well as the similarities between the two very different groups in how they interact socially , how they care for their infants and feed . These two groups shared similarities with human behavior as well, actions that…
Humans and primates are similar in some ways, but they are different in others. As scientist remark, they belong to the same family called Hominidae. They also conclude that they have many similar characteristics because they went through a process that they called evolution. This is the process in which some primates evoluted into what is know a human being and preserved several similar characteristics. It is now known that the chimpanzee is the closest primate to humans since they have a similar protein sequence. Yet since they have a lot of differences, still they are considered non humans.…
One of the difficulties that many non-native speakers face while reading O’Neil’s play is language difficulty. Concerning the language of his play “the hairy ape” we find difficulty specially because he uses a form of writing in terms of spoken in a distorted way to suit the purpose of his play.…
BANGKOK: THE POLITICAL ECONOMY OF A HYPERURBANIZED PRIMATE CITY Gerald W. Fry "The rapid expansion of a deteriorated environment and high social costs are the most obvious and immediate results of this overconcentration process. Eventually, the public investment on the expansion of urban infrastructure will reach a point of diminishing returns. Urban problems can bring national development to the edge of failure. This would be an appalling situation indeed!" Vimolsiddhi Horayangkura1 "Hyperurbanization signifies a prolonged condition of superheated urban growth." John Friedmann2 Bangkok, perhaps more than any other major world metropolis, represents a primate city. It is forty times larger than Chiang Mai, Thailand's second largest city, and dominates Thai political, economic, and intellectual life. Bangkok is simultaneously Thailand's castle, market, and temple.3 Once known as the "Venice of the East," Bangkok has changed dramatically from the tranquil pre-modern days of Joseph Conrad and W. Somerset Maugham. Lynch has emphasized the importance of a city's image.4 Bangkok has diverse images. The Thais refer to it as Krungthep ... meaning City of Angels. In fact, modern Bangkok with its sprawling laissez faire urban development does indeed resemble its American namesake, Los Angeles. Some Thais have called modern Bangkok a concrete jungle.5 Foreign visitors to Bangkok in the 1940s and 1950s would hardly recognize the thriving metropolis of the 1980s with a population of over six million. Prior to 1960, Bangkok had almost no buildings over five stories. Today numerous skyscrapers house the offices of transnational corporations and international agencies.…
