Evolution Theory Essay

Darwin spent quintuple years exploring the world. Darwin traveled to numerous places mainly in the Southern Hemisphere. As he traveled from place to place, Darwin was surprised, by the similarities between the species. He wrote in his journal of the Galapagos Islands, there is even a difference between the inhabitants of the distinguishable islands yet all show a marked relationship with those of America, though separated from that continent by an open space of ocean, between viosterol and 600 miles in width. At this early stage of his life, along with graduating college Darwin soon began assemblage evidence for his theory of Evolution and natural selection. While on his locomote Darwin made many observations. They were mainly about the different species he power saw on the Galapagos Islands. Each island had a different variation of birds. He notice that the beak sizes of the finches were different on each island because of the size seeds they ate.Darwin noticed that organism s procreate more offspring than good deal survive. Each individual offspring has unequalled characteristics that can be hereditable. Most of Darwins observations focused on the root word of natural adaptions. Darwin noticed that the body parts an animal used the most for survival, evolved over periods of time. Meaning if a giraffe tends to use its neck a lot, it will extend in length throughout time. This is an organisms natural adaption to, living within its environment. These observations lead to the theory of Evolution. Aside from this Darwin discovered the competitive field among organisms. An organisms physical adaption can either make or break them. Survival of the fittest is key in all habitat. Through evolution, organisms have been allowed to make physical and behavioral adaptions that can be beneficial towards survival.In his theory Darwin states that organisms have visible differences. This difference can be inherited from the offsprings pargonnts. Another point is t hat organisms produce more offspring than can survive. From these organisms that are produced, many do not reproduce later on in life. Since so many organisms are reproduced there is a fight for the survival of the fittest. Individuals outgo suited to their environment survive and reproduce most successfully. The characteristics that make them scoop up suited to their environment are passed on to offspring. Individuals whose characteristics are not as well suited to their environment die or leave few offspring.Organisms change over time, this is the theory that Darwin tries to prove known as evolution. It is believed that organism adapt t their environment and change over periods of time. The species that live in present day are descendants form those in the past. wholly organisms on Earth are united by one reciprocal ancestor. These are the major points form Darwins theory of Evolution. I looking that Darwins theory is very accurate. Organisms adapt over time and this adaptio ns abet with natural survival. Evolution occurs over periods of time and has leaded us to our innovational state. Every organism is the descendant of a prehistoric ancestor. There are visible similarities, but sometimes it may be hard to bear witness an organisms ancestor. I feel that if changes occur gradually it can be advantageously noticed that organisms physical, behavioral and outer appearances change.
