Darwin s Theory Of Natural Selection - 1128 Words

Charles Darwin broached the theory of natural selection in his book the Origin of Species, which has been considered the basis of evolutionary biology to this day. Natural selection is when populations of a species evolve over the course of many generations. Darwin believed that species were not created separately, but instead, species were derived from one another. In other words, the evolution of species creates many variations among creatures, and this is because all of those species came from a common ancestor, and characteristics changed to increase the species chance of survival. Many scientists believe variations are caused by environmental factors, such as food availability, weather and more; and that species evolve when environmental conditions change to increase the species survival. Darwin censures this idea; he believed that the main cause of variation is due to reproduction (Chapter I). Darwin suggested that parents pass down specific characteristics to their offspring, and those variations are continued on in the following generations. The problem with Darwin’s theory of reproduction is that Darwin did not comprehend how or why some characteristics are perennial and how others are not. Darwin’s inferences on variations also conflict with the idea that God created species independently, which was widely understood by many people in a time where religion was prominent (Chapter II). In chapter III Darwin discusses how the Struggle for existence affects naturalShow MoreRelatedDarwin s Theory Of Natural Selection1638 Words   |  7 PagesWays that Darwin’s theory of natural selection was transformative to his society According to thefreedictionary.com the definition of natural selection is the process in which, according to Darwin’s theory of evolution, organisms that are better adapted to their environment tend to survive longer and transmit more of their genetic characteristics to succeeding generations, than do those that are less well adapted.

Charles Darwin’s theory clearly state that evolution occurs by natural selection. Darwin published a book in 1859 on the origin of species. In the book Darwin talks about the philosophy of natural selection. Natural selection is when a group of species show variation in their physical characters. This is because of the difference in their gene. Charles Darwin proposed that natural selection acts to preserve accumulate minor advantageous genetic mutations (Darwin’s-theory-of-evolution).

The Effects Of Corruption On Economic Growth - 1444 Words

In this essay, I will present an argument against theories that propose that corruption may be beneficial to economic growth by presenting theoretical and empirical evidence that suggest otherwise. I will also discuss policies that will prove effective in eliminating corruption in developing countries. The international handbook on the economics of corruption defines corruption as the use of public resources to fund the private purposes. It usually involves the abuse of official power. Economic growth can be defined as an increase in a country’s ability to produce output over a period of time (Investopedia, 2005). Although the consensus view in economic theory is that corruption has a negative impact on economic growth, there are instances where having a corrupt government has actually encouraged economic growth. These are instances where corruption is described as â€Å"economically expansionary† Osterfeld (1992). Leff (1964), a major proponent of this view has argued that some underdeveloped countries with a high level of bureaucracy and weak governance have been able to allocate resources more efficiently because of corrupt government officials. He argues that is because entrepreneurs and potential investors can sidestep the tremendous bureaucracy in these countries through the use of bribery, they are able to do business more efficiently. The Chinese economy in the 1980’s is evidence that supports this theory because corruption acted as a means toShow MoreRelatedCorruption And Its Effect On Economic Growth1487 Words   |  6 Pagesagainst theories that propose that corruptio n may be beneficial to economic growth by presenting theoretical and empirical evidence that suggest otherwise.

The Bell Jar Essay Thesis Example For Students

The Bell Jar Essay Thesis quot;The Role Models of Sylvia Plaths The Bell Jar;quot;;#9;Throughout the novel Esther Greenwood has trouble deciding who she wants to be. Her search for an identity leads her to look at her female role models. These women are not ideal in her eyes. Although they represent a part of what she herself wants to be, Esther finds it impossible to decide which one she is to become. Jay Cee, Mrs. Willard, Philomena Guinea, her mother and Doctor Nolan all act as role models for Esther Greenwood. The ways in which these women are portrayed reveals a lot about Esthers perspectives on identity and her search for an identity of her own. #9;Jay Cee, Mrs. Willard, and Philomena Guinea are characterized as archetypes and therefore very limiting. Jay Cee is portrayed as hyper, abrupt and she speaks, quot;waspishlyquot; (29). She is smart and talented but she is ugly. Philomena Guinea, on the other hand, says that she was stupid at college and is always described as being surrounded by beautiful things. The beauty that Esther sees as the binary opposite of ugly seems to have been acquired through her quot;millions and millions of dollarsquot; (38). Jay Cee has quot;brains, so her plug-ugly looks dont seem to matter;quot; (5). But, Philomena has money so nothing else matters. Mrs. Willard is portrayed as the ultimate wife and mother. We are given the impression that Mrs. Willard embodies sensibility. She is what every little girl is supposed to grow up to be. But Esther sees differently. Mrs. Willard represents the inevitable outcome of marriage and motherhood to flatten out under the husbands foot like a kitchen mat (80 ). The way the women are described brings to light the kind of relationship she had with them. For example, Esther doesnt even find it necessary to reveal much of anything about the person, Philomena Guinea. Whenever she is mentioned it is about her black Cadillac or her exotic hat or her finger bowls. Esther doesnt embrace her the way she tries to embrace Esther. The only time Esther shows any kind of appreciation for Philomena is when she uses her money to get quot;fittedquot;. It is then that Esther feels that Philomena buys her her freedom when actually she buys Esthers freedom many times over with college scholarships and proper treatment from Dr. Nolan, for instance. Esther rarely refers to Philomena directly, preferring instead to mention her car, her hat, her letters, objects around her, actions of Philomena to other people, but never any direct interaction between Esther and her. This tells me that Esther felt no connection with this woman. Even though Philomena obviously cared a lot for her, she just couldnt connect. The older women in Esthers lives all want to adopt her as their own daughter and influence her or teach her ;quot;and for the price of their care and influence, have Esther resemble them;quot; (211). She complains about this always happening with her and older women, but she effectively internalizes the need to be them. Each of them represents a fig on the tree that Esther cant decide which one to pick. Not only does she consciously try to decide who to emulate, but she is also willing to have them as her mother. She actually wishes she quot;had a mother like Jay Cee. Then shed know what to do;quot; (36). None of these role models are her mother and she doesnt know what to do.#9;#9;Esthers Mother is a powerful role model and has a lot of influence on her. However, Esther comes to the realization that she actually hates her mother. This is a source of intense struggle for Esther. Unlike Philomena Guinea, the mother is described often and intimately. Their conversations are recounted m any times and Esther frequently describes her mothers looks and actions. She does this more so than any of other older role model characters. These descriptions, though, are not generally favorable. Through Esthers eyes we see that her mother has no tact and no consideration for her daughters feelings. Esther is never good enough for her: quot;My mother kept telling me nobody wanted a plain English majorquot; (72). Like the other women the mother is constantly trying to mold Esther into her own image. She symbolizes everything that Esther doesnt want to become. But, since she is the person Esther is the most closely connected to, then Esther is terribly worried about becoming exactly like her mother. When Esther tells Doctor Nolan that she hates her mother she uncovers the recognition of her own self-loathing. This comes directly after Esther refuses to acknowledge her own birthday. She doesnt want to celebrate being born and especially with the woman who made her who she is and con tinues to attempt to shape her in her own image. Esthers fear of being influence by her mother is not unfounded. Her mother is characterized as heartless, inconsiderate, and self-centered and even a martyr. Everything that her mother says always becomes directed at how she herself is being affected. She is shortsighted and thoughtless. Esther herself shows similar characteristics. She leaves Doreen passed out drunk in the hallway of their hotel, she tells Joan that she doesnt like her, shes condescending and she acts like a martyr after being attacked by Marco by leaving the lines of blood on her face: They seemed touching, and rather spectacular, and I thought I would carry them around with me, like the relic of a dead lover, till they wore off of their own accord;quot; (108). .u62c4e5510eba1b3877c7a5aabb4e76f2 , .u62c4e5510eba1b3877c7a5aabb4e76f2 .postImageUrl , .u62c4e5510eba1b3877c7a5aabb4e76f2 .centered-text-area { min-height: 80px; position: relative; } .u62c4e5510eba1b3877c7a5aabb4e76f2 , .u62c4e5510eba1b3877c7a5aabb4e76f2:hover , .u62c4e5510eba1b3877c7a5aabb4e76f2:visited , .u62c4e5510eba1b3877c7a5aabb4e76f2:active { border:0!important; } .u62c4e5510eba1b3877c7a5aabb4e76f2 .clearfix:after { content: ""; display: table; clear: both; } .u62c4e5510eba1b3877c7a5aabb4e76f2 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u62c4e5510eba1b3877c7a5aabb4e76f2:active , .u62c4e5510eba1b3877c7a5aabb4e76f2:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u62c4e5510eba1b3877c7a5aabb4e76f2 .centered-text-area { width: 100%; position: relative ; } .u62c4e5510eba1b3877c7a5aabb4e76f2 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u62c4e5510eba1b3877c7a5aabb4e76f2 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u62c4e5510eba1b3877c7a5aabb4e76f2 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u62c4e5510eba1b3877c7a5aabb4e76f2:hover .ctaButton { background-color: #34495E!important; } .u62c4e5510eba1b3877c7a5aabb4e76f2 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u62c4e5510eba1b3877c7a5aabb4e76f2 .u62c4e5510eba1b3877c7a5aabb4e76f2-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u62c4e5510eba1b3877c7a5aabb4e76f2:after { content: ""; display: block; clear: both; } READ: Pride And Prejudice By Austen EssayThere is also evidence that Esther actually does admire her mother. She talks about how she and her grandmother were ;quot;such good a cooks;quot; (71) and seems genuinely disappointed that she didnt learn the recipes that these women where trying to teach her. She admired her moms history of speaking German and desired to learn it as well: ;quot;My mother spoke German during her childhood in America and was stoned for it during the First World War by the children at school;quot; (30). At one point Esther even briefly decides to learn shorthand. This need to be like her mother while at the same time hating her is enough to disturb Esther and stir up fears of being too close to what she ultimately wants to avoid. ;#9;Doctor Nolan is a positive influence on Esther. Before she came along Esther could only see the archetypes. She felt like she had to choose whom she was going to resemble, the poet, the editor, the wife or the mother. Doctor Nolan, however, represents something new all together, something she never even knew existed a complete woman. A woman who doesnt sacrifice part of herself in order to fulfill a need. She is a professional. She is loving, nurturing and maternal. She advocates sex for the pure pleasure, not procreation. She is attractive as well as being smart. She is cool and composed. Dr. Nolan never tries to control her like so many others have. The others try to adopt her and control her like her mother, but Doctor Nolan doesnt do that. She just tries to be there for Esther and Esther adopts her as her mother. Doctor Nolan doesnt fit into Esthers preconceived notions of who a woman should be. Esthers indecision about who she should be and her self-loathing because of the apparent inevitability to turn into her mother are thrown for a loop. She starts to see things differently. She loves Doctor Nolan because she embodies everything her mother is not and everything that is possible for Esther to become. The description of Doctor Nolan as a complete woman reveals that Esther admires Doctor Nolan a great deal. #9;The way each of the women is portrayed reveals a lot about Esthers perspective. Esther stresses over the choices she feels like she has to make. Her role models contribute to the decisions that she ultimately must make. They dont contribute the way Esther thinks they intended to but rather by making the decision impossible they have collectively contributed to Esther leaving the role models behind and seeking out her own identity. nbsp;
