Charles Darwin was an English naturalist and geologist. Darwin is best known for his contributions to the theory of evolution. Through his various experiments, observations, and studies, he established that over the progression of time, all species of life forms have descended from common ancestors. At first, Darwin was skeptical of his theory, and was afraid of what opinions others would behold upon him if he publicized his theory as he had developed a good reputation amongst the scientific community, and did not want to tarnish his reputation. (Desmond) Darwin’s main observations and findings that lead him to his conclusion and theory of evolution mainly originated from his voyage upon the HMS Beagle. The voyage on the HMS Beagle lasted a total of almost 5 years. Over the course of this voyage, the primary focus of observation was South America. On this voyage, Darwin spend many days trekking on foot the various rainforests in South America, and was exposed to several different new kinds of species of animals. One of his biggest findings was the variation in beak sizes for several different variations of finches from the Galapagos Islands. Darwin identified species of finches collected from the Galapagos. He was puzzled because he only had prior knowledge of one species of the bird which was on the mainland of South America, about 600 miles away. He then concluded that the when the South American finches arrived at the islands, they dispersed and were exposed to several different environments and environmental conditions. This exposure then forced them to adapt to different conditions. Over the many generations, they uniquely adapted so that they were able to successfully survive and reproduce offspring within their unique environments. (Colburn) His conclusion on evolution was that evolution is a naturally occurring process caused by natural selection. Natural selection is the process through which species that are better suited with the advantageous trait for survival and reproduction within their particular environment tend to survive and produce more offspring. This then results in the advantageous trait becoming more prevalent within the population which over the course of times results in significant changes in both phenotypes and genotypes whose end result is evolution. (Desmond) Changes in the environment, whether naturally occurring or induced by humans, have an impact on the surrounding ecosystems and the species of organisms that inhibit them. One example of a changing environment is the industrial evolution. The industrial evolution was the transition to a new form of manufacturing processes which occurred from the late 1700’s to early 1800’s. During this period of time, transitions were made in terms of manufacturing processes. A significant outcome of the industrial revolution was the transition from handmade/ hand production methods to machines. Also involved were new chemical manufacturing and iron production processes. This then further improved the efficiency of water power, which lead to the increased use of steam which then eventually lead to the development of machine tools mainly powered by steam. The industrial evolution was also a major turning point in human history. However, the industrial revolution did have a negative impact on the environment. The revolution also included the transition from wood and other bio-fuels to fossil fuels such as coal. This then lead to an increased amount of “smog” and greenhouse gases polluting the surrounding environment and ecosystems, and disrupting them. (Dickens) Variations in traits are important for the survival of a species as in some cases one trait may be more advantageous to survival and reproduction than another trait. This then also compliments and contributes to genetic diversity resulting in a population better able to fight off disease and to successfully survive and reproduce as those with the advantageous trait would be able to survive the occurring event or disaster, and therefore be able to continue to produce offspring. This would then lead the end result of the event to not being an extinction of the species, as the species would be preserved by those with the advantageous trait to continue to survive.
