The Future Of Human Evolution Essay -- essays research papers

The Future of Human Evolution Evolution, the science of how populations of living organisms change over time in response to their environment, is the central unifying theme in biology today. Evolution was first explored in its semi-modern form in Charles Darwin 's 1859 book, Origin of Species by means of Natural Selection. In this book, Darwin laid out a strong argument for evolution. He postulated that all species have a common ancestor from which they are descended. As populations of species moved into new habitats and new parts of the world, they faced different environmental conditions. Over time, these populations accumulated modifications, or adaptations, that allowed them and their offspring to survive better in their new environments. These modifications were the key to the evolution of new species, and Darwin proposed natural selection or "survival of the fittest" as the vehicle by which that change occurs. Under Natural Selection, some individuals in a population have adaptations that allow them to survive and reproduce more than other individuals. These adaptations become more common in the population because of this higher reproductive success. Over time, the characteristics of the population as a whole can change, sometimes even resulting in the formation of a new species. Humans have survived for thousands of years and will most like survive thousands of more. Throughout the history of the Huminoid species man has evolved from Homo Erectus to what we today call Homo Sapiens, or what we know today as modern man.. The topic of this paper is what does the future have in store for the evolution of Homo Sapiens. Of course, human beings will continue to change culturally; therefore cultural evolution will always continue; but what of physiological evolution? The cultural evolution of man will continue as long as man can think; after all it's the ideas we think up that makes up our cultures. In a thousand years man might complete a 180 degree turn culturally (not to mention physiologically) and as seen by our fellow inhabitants of earth we would in essence be different beings. One can say that this new culture has chosen its ideas based on Natural Selection. One can see this in the spread of ideas in the past history of homo sapiens, the ideas which cause man to succeed are chosen such as science and demo... ...random genetic drift, but it may become homozygous for allele "A", whereas the first population has become homozygous for allele "a". As time goes on, isolated populations diverge from each other, each losing heterozygosity. The variation originally present within populations now appears as variation between populations (Suzuki 704). The evolution of man can be broken up into three basic stages. The first, lasting millions of years, slowly shaped human nature from Homo erectus to Home sapiens. Natural selection provided the means for countless random mutations resulting in the appearance of such human characteristics as hands and feet. The second stage, after the full development of the human body and mind, saw humans moving from wild foragers to an agriculture based society. Natural selection received a helping hand as man took advantage of random mutations in nature and bred more productive species of plants and animals. The most bountiful wheats were collected and re-planted, and the fastest horses were bred with equally faster horses. Even in our recent history the strongest black male slaves were mated with the hardest working female slaves.

British Airway External Environment Analysis Porter’s Five Forces In order to have a well – planned development of organisation future strategy, it is crucial to analysis the competitions within the industry, which may be threaten to the business. Porter (1980) developed a framework and proposed five forces that may affect the degree of competition with other competitors. These five forces are the threat of new entrants to the industry; the threat of substitute products; the power of buyers or customers; the power of supplier and rivalry among businesses in the industry (Johnson, Scholes, Whittington, 2008). Rivalry among competitors Competitive Rivalry BA is facing a very high competitive rivalry, as recent years, higher competition among the short haul flights, budget airline such as Easyjet and Ryanair have been very popular, the old- established airlines such as Virgin Atlantic and Cathy Pacific have also been in a high market competition, according to Shaw (2004), they almost used the same models of aircrafts. Also the government has a strict control on the frequencies and the timing of the flight slot, and also strict pricing policy. Therefore, reputation of the airlines becomes more important for the customers to be loyal.

The Dividing Lien of Platos Allegory of the Cave Essay

Plato’s allegory of the cave, located in Book VII of The Republic is one of the most famous allegories in which he has created. This simile touches base on a number of philosophical ideas which Plato developed over the progression of The Republic (Plato, G.M.A Grube, 1993), the most noticeable being the dividing line. The dividing line is the point between the world of ideas where we live and the world of the forms which is in the heavens. This allegory of the cave helps people understand the theory on which philosophy is based. It is also in this Book where the education of the guardians is outlined. We are asked in Book VII of The Republic to imagine a group of people sitting inside a cave, with their hands and feet bound. It is by†¦show more content†¦When the prisoner turns his head towards the light of the fire his eyes hurt him and he is confused because he is unable to see the objects of the shadows he had been subjected to his entire life. It is because of this pain and confusion that the prisoner wishes to return to the life that he is accustomed to, and the reality he knows, the world of the shadows. We are asked to envision the stubbornness displayed by this prisoner to leave the world of the shadows, a stubbornness which causes him to be dragged into the sunlight. Upon seeing the light of the sun the prisoner is temporarily blinded, unable to see anything around him, blinding him more than when he was a prisoner of the cave. Eventually the prisoner’s vision adjusts and he is able to see more clearly. His mind will first be able to recognize the shadows, then moving on to reflections of objects in the water, and lastly the objects themselves. This new sight leads the prisoner to question the colours and objects around him. He questions what it is that causes him to being able to see all the things he can, compared to only seeing poor reflections of objects in the cave. The prisoner eventually concludes that it is the sun wh ich illuminates all around him and is the source of his sight. This now knowledgeable individual remembers the others who are still trapped in the cave ignorant to the wonders which lay outside of it. He considers him self lucky to
