The Evolution Of Primate Locomotion And Body Configuration Essay

The Evolution Of Primate Locomotion And Body Configuration - Essay Example In 1956, while searching through a collection of fossils at the American Museum of Natural History, I came across a small piece of forehead bone, identified as a "possible primate," that had lain neglected for half a century. It had been recovered from the Fayum badlands, sixty miles southwest of Cairo, Egypt, by an amateur collector named Richard Markgraf. The rock in which it was found was known to belong to the geological epoch we call the Oligocene (now estimated to have lasted from 34 to 23 million years ago). Although only the size of a quarter, the fossil displayed two defining characteristics of the Anthropoidea, or higher primates--the large evolutionary group that includes monkeys, apes, and humans. I could tell that the right and left frontal (forehead) bones in this small animal were fused along the midline suture into a single bone, as is the case in all the higher primates. And on the right side, just enough of the rim of the eye socket was preserved for me to establish that it was fully enclosed in the back by bony plates (the eyeballs of more primitive primates are normally encircled by just a thin bar of bone). Neither feature had been previously documented in so old a fossil. Better late than never, the small piece of bone joined a short list of other fossils discovered in the Fayum between 1906 and 1910 that also appeared to belong to higher primates. The best of the other fossils--both nearly complete mandibles--belonged to two small species named Parapithecus fraasi and Propliopithecus haeckeli. Both have lower molars with anthropoidean features--in particular, they are broad and flat and have five cusps. (Miyamoto 197-220) In addition, Propliopithecus has the same number of the different types of teeth as other Old World anthropoideans, and the two sides of the lower jaw are solidly fused together in the front, another important characteristic of higher primates. My interest sparked by these tantalizing finds, I began doing fieldwork in the Fayum more than thirty years ago. Since then, my teams and I have succeeded in gathering hundreds of additional primate fossils, documenting the presence of eleven primate species in Oligocene deposits that are 30 to 33 million years old. The largest of these species, a close relative of Propliopithecus, is Aegyptopithecus zeuxis, a cat-size creature that appears to stand at or near the base of the family tree of the Old World monkeys, apes, and humans. We have collected several skulls and faces of Aegyptopithecus, as well as many bones from the rest of its skeleton (see "Dawn Ape of the Fayum," Natural History, May 1984). Many of the eleven Oligocene species have anthropoidean features, including the fused frontal bone, enclosed eye socket, lower jaws that are solidly fused together in the front, and the broadened and flattened lower molars with five principal cusps. In certain details, the upper molars also resemble those of more recent higher primates. Another anthropoidean characteristic is the manner in which the bony ring encircling the eardrum lines the auditory opening at the side of the skull. The eleven species are diverse in many respects, however. By 1985, I had accumulated enough evidence to say that they fell into several different taxonomic families or subfamilies. Given that so much diversity had evolved, I had to conclude that the common ancestor of all the higher primates must go back a long way in Africa. This was only the beginning, however, for in 1983 a Fayum site called Locality 41 had been discovered. Its exposed deposits came from a much deeper layer than those of

Entrepreneur - link literature review theories to real life Essay

Entrepreneur - link literature review theories to real life entrepreneur - Essay Example The so called killer phrases are also sometime referred to as one of the real barriers behind the process of creative thinking. However in order to overcome these barriers to the creative thought process, resources are required which might include the right attitude adopted by the entrepreneur. Creativity and innovation are probably the two ways through which entrepreneurs make difference in the world. This assumption of having creative and innovative entrepreneurs is based on the fact that every entrepreneur has certain personal traits and motivations and key element of this is their ability to put their efforts and endeavors behind it. Probably the most innovative and creative endeavor of entrepreneur is his ability to create capital. (Thompson, 1999). By adding value and creating capital, entrepreneurs basically transform their business activities in the larger good of the society. It is largely believed that the success of entrepreneurship therefore base on the personal traits of the entrepreneur which include his ability to be an intuitive thinker and innovator. The notion of creativity and innovation is associated with the process of entrepreneurship because of the fact that creativity is often considered as the personality trait of the entrepreneur. (Thompson, 2004) . This approach tends to focus on the role of people in developing creative and innovative enterprises. Many researches have suggested that the competitive advantages which entrepreneurs enjoy over their competitors are based on their internal resources. These internal resources are often linked with knowledge based resources which are ultimately linked with the innovation and creativity of the entrepreneurs. (Mosakowski, 1998). These knowledge based intangible resources flourish creativity and innovation in entrepreneurs. However these knowledge based intangible resources

Having our say and black men and public space (racism) - Essay Example The African American life is detailed in these stories. The story has a purpose of promoting harmony, courage and equality among American people. The stories talks about the mean ways of human and how they think color of skin decides the quality of a human. The writers alerts us that racism is an obstacle which is not easy to overcome and one need lot of determination and willpower to succeed in life in such a situation. Both the stories tell us that black people are treated in public place with despise and hatred. These narrations make us realize the hard life of black people in America who had to face racism throughout their life. They feel stolen of their identity, rights and freedom. They had to face racist attack at school, restaurants, public transport and work. This kind of alienation put forward a kind of resentment, revenge and frustration among black population. The black sisters in the novel â€Å"Having our say† talk how they handled the racism. One of the sisters responds strongly while the other one was submissive. This reality as many do not respond to criticism while some may be expressive. Staple understands that such racist view can hurt one immensely but keeps silence as he think it is a better way to face the situation. The racism is unfortunate for a country like America where people are educated and civilized. These readings show that education necessarily does not mean being civilized. The reading â€Å"Black men in public space† indicate that black people are often taken as criminals. Black men are often mistaken for being a rapist, mugger or burglar. People lock their doors or stay away when they see black men at public places. It is as if the black people represent crime and white people are perceived as moral and decent. The author of this tells that he has been mistaken for being a criminal many times which shows the ignorance and racist attitudes of white race. The author claims that white people have a misconception

Alfuttaim motors have the greatest number of its vehicles on the road as compared to other automobile manufacturers in the world. Its vehicle brands target both the middle-class economy as well as the first-economy economy (Nayak & Josh, 2012). Its vehicle brand, the Lexus, targets the first-class economy. This is because it is quite expensive and it can only be afforded by people who consider themselves as falling under the category of first-class. The sales of this Lexus brand are however minimized by the stiff competition from the German machines like the Mercedes Benz and the BMW. The majority of the sales of the Alfuttaim motors are the Toyota. This is because these types of vehicles are affordable to the middle-class in the economy. It is also notable that the middle-class makes up the largest percentage of the people in the world.

It also makes luxurious cars, for example the Lexus,

Market Structures Essay Example | Topics and Well Written Essays - 750 words - 2

Market Structures - Essay Example Monopolistic competition along with oligopoly constitutes the structure of imperfect competition. Firms that are imperfectly competitive offer many products. The products are offered at administered prices. The price changes are costly and slower. The prime prediction of the theory of monopolistic competition is that firms will produce at the level where marginal cost equals marginal revenue in the short run. However in the long run, the firms will operate at zero profit levels and the demand curve will be tangential to the average total cost curve. The figure shows the marginal cost curve for the monopolist (MCsm) for the short run. MCsm is the summation of the short run supply curves (SRSc) in the competitive market. The loss of producers’ surplus (area B) and consumers’ surplus (area B) arises from the profit maximizing decision of the monopolist. A monopolistically competitive firm can operate above the level of normal profit. The above figure represents the economic loss for a monopolistically competitive firm. For a monopolistically competitive firm economic profits are zero and at equilibrium average total cost equals price. Both the firms in monopolistic competition and perfect competition are able to zero profits in the long run. It is possible for a firm operating in the monopoly market to acquire economic profits in the long run. The price is greater than the minimum point of Average total cost curve in the long run but in perfect competition price equals minimum of average total cost. In perfect competition price is lower and output is higher than monopolistic competition. A form of market where the industry is dominated by small number of sellers is called oligopoly. Each oligopolist is aware of the market conditions as few sellers are present in the market. The decision of one firm can influence or are influenced by other firms. The responses of the participants of the market are taken into account in

Mahatma Gandhi- A Hindu Saint Essay Example | Topics and Well Written Essays - 1250 words

Mahatma Gandhi- A Hindu Saint - Essay Example Having developed his ideas in South Africa, Gandhi remained committed, through numerous internal and external trials, to his fundamental Hindu beliefs – that love could indeed conquer all – all of which contributed to his ability to change the world. His life ended with an assassin’s bullet on January 30, 1948. The militant who shot him blamed Gandhi for the weakening of India yet today Gandhi is hailed as the father of India and has inspired numerous individuals to lead further social reform in other parts of the world. Building off of his early childhood influences and religious ideals, Gandhi accomplished the changes he did by putting together logical strategies for non-violent political action as a means of addressing humanitarian concerns in both South Africa and India. The main beliefs Gandhi held related to his firm conviction that Indians, as British subjects, were every bit as worthy of fair treatment as whites. He did not feel the Indians should be granted special privileges as is shown in an early statement regarding poverty: â€Å"[W]hile the poor man must strive to improve his condition, let him not hate the ruler and wish his destruction †¦ He must not want rulership for himself, but remain content by earning his own wants. This condition of mutual cooperation and help is the Swaraj [freedom] of my conception† (Arnold, 19). Gandhi’s early traditions taught him to revere all life and he remained a vegetarian for most of his life as a result. He also envisioned the goal of life to be recognition of one’s duty toward others and responsibility to uphold the truth. Early in his life, he managed to apply one of the stories from the Bhagavad Gita to his own life. â€Å"Gandhi saw the battle in which Arjuna was engaged a s an allegorical, not an actual, call to arms, a demonstration of the supreme importance of

There is a constant shift from soft notes to hard ones, marking it as a very dynamic piece. It requires a great deal of dexterity from its performer, especially to keep the constant swarm of notes going. It is very brisk and seems to be in a great rush, bouncing off the walls at a dizzying pace. In the middle, it begins to slow down a bit, before playfully speeding up again. I find this to be a cheerful, funny piece, and can easily imagine people smiling as they try to dance to it. 2.) Discussion Questions: Art. The impressionist style of painting is characterized chiefly by concentration on the general impression produced by a scene or object and the use of unmixed primary colors and small strokes to simulate actual reflected light. -Nicholas Pioch Impressionism is often a kind of soft-focus style of painting where the figures or objects appear in varying levels of detail. The world of light has more influence on our sight than you might expect, is what impressionist seem to be saying. They try to shift our allegiances from strict forms to a vaguer, airier world. They use soft colours that blend into one another and often capture pastoral scenes. They question how we perceive the world and what our visual prejudices might
