Evolution Theory Essay

Darwin spent five mean solar days exploring the world. Darwin traveled to many 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 til now a difference between the inhabitants of the incompatible islands yet all show a marked relationship with those of America, though disconnected from that continent by an open topographic point of ocean, between 500 and 600 miles in width. At this early stage of his life, along with graduating college Darwin soon began collecting evidence for his theory of phylogeny and pictorial selection. While on his journey Darwin made many observations. They were mainly al to the highest degree the divers(prenominal) species he saw on the Galapagos Islands. Each island had a different transition of birds. He detect that the beak sizes of the finches were different on each island because of the size seed s they ate.Darwin noticed that beings re nominate more offspring than arse survive. Each individual offspring has crotchety characteristics that fucking be hereditable. Most of Darwins observations focused on the idea of natural alineions. Darwin noticed that the body parts an wolf used the most for survival, evolved over periods of time. kernel if a giraffe tends to use its spot a lot, it will extend in length throughout time. This is an organisms natural adaption to, living within its surroundings. These observations happen to the theory of phylogeny. Aside from this Darwin observed the warring field among organisms. An organisms sensual adaption can either accomplish or break them. Survival of the fittest is key in every habitat. Through evolution, organisms bind 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 t he offsprings p arnts. some other point is that organisms produce more offspring than can survive. From these organisms that be produced, many do not spue later on in life. Since so many organisms are reproduced there is a fight for the survival of the fittest. Individuals best meet to their milieu survive and reproduce most successfully. The characteristics that make them best suited to their environment are passed on to offspring. Individuals whose characteristics are not as well suited to their environment die or leave less offspring.Organisms change over time, this is the theory that Darwin tries to adjudicate 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. All organisms on Earth are united by one jet ancestor. These are the major points form Darwins theory of Evolution. I feel that Darwins theory is very accurate. Organisms adapt ove r time and this adaptions help with natural survival. Evolution occurs over periods of time and has leaded us to our modern state. Every organism is the descendant of a prehistoric ancestor. There are visible similarities, but sometimes it whitethorn be hard to tell an organisms ancestor. I feel that if changes occur gradually it can be easily noticed that organisms physical, behavioral and outer appearances change.
