Analyzing Wallace's Theory Of Natural Selection

Charles Darwin (1809-1882) was a British naturalist who became famous for his theories in evolution. He believed all species evolved form a common ancestor and that evolution happened through a process called natural selection, which meant survival of the fittest. In the BNW, the different castes of people were made from a common ancestor (a single individual). Thus, creating hundreds of his or her clones. Since the directors believed in survival of the fittest, they made the best kind of people so that they may live long in a specific environment.

Over the last several years, evolution has been playing an increasingly important role in determining how various species are evolving. This is because ecology will have an impact on how quickly a particular organism is able to adapt (with: the unique challenges for a particular environment). To determine the effect that this is having requires carefully examining different species over the course of many years. This will be accomplished by comparing these changes on Darwin and Wallace Islands. Once this occurs, is when specific insights will be provided that are highlighting the underlying challenges affecting the development of organisms. This is the point that these transformations will be evident among the various life forms. (Fasolo, 2011, pp. 53 68)

His first proposition was that the natural tendency for species to progress towards a high form. He also proposed the inheritance of acquired characteristics such as giraffes having longer necks because they reached for higher food. Generations of giraffes after had longer necks because of this evolutionary change. Next, Wallace gave his idea of Natural Selection saying the inherited trait variations, those that lead to increased survival will most likely be passed on to succeeding generations. The three concepts to this theory is variation, inheritance, and sexual selection. Darwin could not explain how the peacock survived evolution because in his eyes only the strongest survive, and the elaborate colors and big feathers of the peacock wouldn’t help survival. Sexual selection helped Darwin explain how the Peacock survived. The beautiful survive because the mates want them and they are the ones who reproduce and keep their genes going on. Other cause of evolutionary change are genetic drift, mutations, founder effects and genetic

Although Darwin’s (1809-1882) work in evolutionary observation might appear radically different from those focused on other areas, the theories he developed from these observation lead to such groundbreaking publishing’s as The Origin of Species. These intern caused an upset within the then accepted norms of philosophy and religion, had a profound impact on the academia, and further

Upon his return to London Darwin concluded thorough research of his notes and specimens many ideas. Out of this study grew several related theories: one, evolution did occur, two, evolutionary change was gradual, requiring thousands to millions of years, three, the primary mechanism for evolution was a process called natural selection, and four, the millions of species alive today arose from a single original life form through a branching process called "specialization."

Lyell convinced Darwin to publish his theory before someone beat him to it. Darwin started to write a detailed book about natural selection. While Darwin was writing his book, he was still in Malay Archipelago and was sick so he spent his time writing a detailed essay about natural selection and only the fittest animals will survive and sent it to Darwin for both of them to check his work. Lyell and Hooker went behind Darwin and Wallace’s back and took Wallace’s paper and two of Darwin’s papers about natural selection and presented them to a meeting of the Linnean Society of London where they were published together and Darwin would earn the most credit for the work. Wallace did receive some credit for natural selection, which still remains the primary explanation for adaptive evolution. Wallace not only created the theory of natural selection he came up with “Wallace Line” which extends between Bali, Lombok, Borneo, and Sulawesi. The line marks the limits of many Asian animal species to the east and limits western extent of Australian animal species (Beccaloni, Smith

Alfred Russel Wallace may not be well known outside of the scientific community, but his contributions to the Theory of Evolution were invaluable to Charles Darwin. In fact, Wallace and Darwin collaborated on the idea of natural selection and presented their own findings jointly to the Linnean Society in London. Alfred Russel Wallace has become not much more than a footnote in history in that regard due to Darwin publishing his book On the Origin of Species before Wallace could publish his work.

Alfred Wallace is a priceless historical figure in the scientific community, more so in his own time than today. Wallace’s life was full of unfortunate twists; from illnesses to shipwrecks he had been through it all. However, none of these twists is more unfortunate than how he is remembered by history, or rather, how his has been forgotten by it. Alfred Wallace was one of the first to construct the theory of Natural Selection and how it drives evolution only to be beaten to the punch by Charles Darwin, who is usually credited with the theory. That’s not all Wallace did though; he also drafted maps, collected new species in Malaysia and was quite popular in his own time for these discoveries. Yet despite his struggles and his accomplishments,

Darwin’s observations from the islands made him want to come up with some explanation to why this occurred. He began to do research of each the species that had lived on these islands and observe all of the

Charles Darwin and Alfred Russel Wallace two different people yet one same idea. Charles Robert Darwin was an english naturalist whose theory of evolution by natural selection is defined as the “foundation of modern evolutionary theories.” Darwin and Wallace both lived during the same period of time in the mid 1800’s and both studied natures theory of evolution. Let us get into the evolution of Mister Charles Darwin. Alfred Russel Wallace was another English naturalist who also came up with the idea of evolution by natural selection at about the same time as Darwin. Darwin began his bold discoveries after a voyage around the world in 1837 through 1839, where he spent around twenty years on his studies of his theories, in which he waited almost two decades to unleash his discoveries.

Alfred Wallace was one of the first to use the theory of evolution to conclude that the possibility of life on other planets is possible. For life to exist on other planets, there would have to be such perfect conditions to align again, those close to the conditions Earth had when life started. Whewell based his beliefs on astronomy and he believed that humans were unique in nature. Whewell also claimed that since the Earth was special, it was in the center of the universe, the perfect place to sustain life. Whewell claimed that the universe was in fact not infinite and the stars proved why. Wallace

Both Wallace and Darwin explored the proposals that had been set forth by the likes of Lamarck, Lyell, and Thomas Malthus. In 1858 the Linnaean Society of London published the contributions of both Wallace and Darwin, which although had significant differences shared the framework of proposing decent with modification based on natural selection. The principle of natural selection provides the rationale of how changes occur in a species over time. It represents the sum total of all environmental factors exerting pressure on a species. The pressure either benefits an organism that has a favorable variation; triggering a natural advantage to the survival value of that organism/species, or either the pressure exposes weaknesses in an organism/species that has unfavorable variations. Unfavorable

Charles Darwin broached the theory of natural selection in his book the Origin of Species, which has been considered the basis of evolutionary biology to this day. Natural selection is when populations of a species evolve over the course of many generations. Darwin believed that species were not created separately, but instead, species were derived from one another. In other words, the evolution of species creates many variations among creatures, and this is because all of those species came from a common ancestor, and characteristics changed to increase the species chance of survival.

Some reasons why beaks were thought to be so useful for testing Darwin’s theory of natural selection was because it seemed that the more favorable variations in their beaks will be passed down. Another reason was because there were more variations in the beaks depending what the finches ate so he could study a variety of beaks.

Through the work of curious minds before them, Darwin’s inspiration working as a naturalist on the HMS Beagle and traveling to the Galapagos Islands, and Wallace’s promptings for publication in 1856,
