Evolution and Darwinism essays

Evolution and Darwinism essays In The Origin of Species, Charles Darwin poetically entailed, "There is grandeur in this view of life . . .." Personifying Nature as the ultimate breeder, Darwin infers and hypothesizes what is arguably the most fundamental and profound scientific manifesto that governs what we now know about modern science and the science of discovering our past. His two theories of Natural Selection and Sexual Selection effectively bridge the gap that his predecessors could not. These concepts are imperative as their implications paved the way for Darwin's explanation of Evolution. The term "Survival of the Fittest" has been made synonymous with Darwinian ideology, yet to fully understand this idea we need to know what it truly means to be "fit." As discussed in class, being fit does not necessarily imply fitness on a physical or mental level. Rather, the principle entails how well-suited one is for its environment or a readiness for a species to adapt, whether to a new habitat or possibly changes in food, shelter, climate, etc. Through small, almost unnoticable change, over large periods of time, organisms develop physiological and/or anatomical features that invariably help the organism live or live easier. It is important to note that this does not infer that the process of adaptation takes place for the mere purpose of only "bettering" a species or self-improvement, rather modifications are a supplemental benefit. Darwin stated that, "if they be in any degree profitable to the individuals of a species, in their indefinitely complex relations to the organic beings and to their physical conditions of life, will tend to the preservation of such individuals . . .." In some cases this modification can be a detriment to a species. Take for example a species of like-moths in England preceding and during the Industrial Revolution. Before the manufacture of goods in large quantities, two types of moths, white and gray would rest on the ...
