idea of bringing back a species from extinction throughout his essay. With examples such as the Pyrenean ibex‚ mammoths‚ passenger pigeons‚ and gastric brooding frogs‚ he discusses how technology and science have advanced to the point that de-extinction is close to being a reality. Zimmer then shifts to the benefits and problems that could arise if we are able to revive an extinct species. As a result‚ Zimmer raises the question that should we bring back an extinct species just because we can? Even

Word Count: 1766 The Arguments in the Origins of Species Evolution involves organisms developing better adapted traits over time. Darwin explains how these specific traits come about through his “one long argument.” In this paper‚ I argue that Charles Darwin’s approach to natural selection is the most accurate depiction of our earth’s history. I begin with a breakdown of Darwin’s theory of evolution‚ then incorporate Darwin’s thoughts on “fitness” and why other scientists may contend against them

‘Fixed species concept’ states that the creator created each species for the specific purpose. Carolus Linnaeus was the major proponent of the fixed species concept. The fixed species concept originated from the belief that the Earth and the life on it are around six hundred thousand years old. The basis of the concept is the organismal adaptations. It was believed that the creator designed every species for a particular use. Plato’s idealism suggests that organisms are already accustomed to their

In the three essays that we were assigned to read have connections. In “Serving in Florida” by Barbara Ehrenreich‚ she decided to work in low paying jobs that pay minimum wage. An example of this is when it states “the multinational mélange of cooks; the dishwashers‚ who are all Czechs here” (364). This example relates to Diana Kendall when it states‚ “The working class and the working poor do not fare much better than the poor and homeless in media representations” (428).

U.S. Fish and Wildlife services have officially removed the gray wolf from the endangered species list calling the recovery‚ “one of the most remarkable success stories in the history of conservation.” “There are an estimated 7000 to 11‚200 gray wolves in Alaska‚ 3‚700 in the Great Lakes region and 1‚675 in the Northern Rockies” (Defenders of Wildlife 1). The gray wolf is no longer on the endangered species list because the numbers have risen so dramatically. Hunting should be allowed‚ as there is

Antioxidant Effects on Reactive Oxygen Species Abstract Antioxidants are among key molecules for a healthy living. Antioxidants are molecules that prevent damage of cells through inhibition of oxidizing agents such as free radicals. This experiment was aimed at investigating the role of antioxidant on the inhibition of reactive oxygen species. To demonstrate this‚ quercetin was used as antioxidant and its effect on reactive oxygen species examined. RAW 264.7 cells were

Mivart’s ‘Genesis of Species’ In George Mivart’s ‘Genesis of Species’‚ Mivart thoroughly reviews Darwin’s theory of natural selection. Mivart concludes that Darwin’s theory of natural selection is flawed because it cannot account for all of the mechanics of inheritance‚ specifically the initial developments of useful characteristics. He disputes that natural selection can account for the passing of negative or unnecessary traits‚ or for individualized traits occurring in only one species. He also asks
