Darwins Theory of Natural Selection - 2096 Words

Charles Darwin revolutionized biology when he introduced The Origin of Species by Means of Natural Selection in 1859. Although Wallace had also came upon this revelation shortly before Origins was published, Darwin had long been in development of this theory. Wallace amicably relinquished the idea to Darwin, allowing him to become the first pioneer of evolution. Darwin was not driven to publish his finding, which hed been collecting for several years before Wallace struck upon it, because he had never come across a single [naturalist] who seemed to doubt to permanence of species (Ridley, pp. 70). What follows are the key points of Darwins Theory of Natural Selection taken directly from the two chapters concerning it in his book†¦show more content†¦This is also known as ordinary selection because it begins with one individual and its constitution and habits. Another method of Natural Selection is sexual selection. Sexual selection arises from interspecies cross breeding. Thi s, Darwin explains, deviates from the struggle for existence and becomes the struggle for progeny. Advances in an individual will often allow it a better chance to procreate. A males ability to woo the female by singing, shows of strength, or decoration have definite effects as to whether or not he will be able to mate. The same goes for the females ability to attract the males attention. Some of these techniques or differences can also sometimes be used in the struggle for existence giving that particular variation the advantage. Lastly, Darwin explains extinction and divergence of character in relation to Natural Selection. With extinction Darwin shows it is necessary for the adapted variation to proliferate. As the adapted variation begins to increase in numbers because of its greater ability to survive conditions, its obvious the older variety must become rarer. Rarity is the first sign of extinction, because with smaller numbers, there is a smaller chance of propagating, and a smaller chance of adapting. This will eventually lead toShow MoreRelatedDarwins Theory of Natural Selection and the Evolution of Animals673 Words   |  3 Pages Darwin’s theory of natural selection has provided us with the explanations of the processes involved in the changes of species over long periods of time. His theory was based on five major assumptions: VARIATION: When Individuals within a species differ from one another in physical characteristics and in their behaviour. HERITABILITY: Some of the variations amongst the members of species is inherited, meaning that the offspring tend to resemble their parents moreRead MoreThe Political Implications of Darwins Theory of Natural Selection878 Words   |  4 PagesIn 1859 biologist Charles Darwin published On the Origin of Species which laid out Darwins theory of natural selection. Natural selection stated that an organism which possessed advantageous traits that allowed it to survive and reproduce easier than became more prevalent in the proceeding generations, eventually resulting in a differentiation of species. This is the basis of evolution and is a constantly ongoing process. Organisms that did not possess the advantageous traits were doomed to geneticRead MoreCharles Darwins Theory of Evolution by Natural Selection Essay1027 Words   |  5 Pages Darwin is considered by other people as the creator of Evolution. Darwin was not the only man to arrive at the theory of evolution. Darwin came to his theory of evolution at the same time as an another man who goes by the name of Alfred Russell Wallace came to the same conclusion. Wallace being relatively unknown was not respected for having the same conclusion because the fact that people were so apt to listen to the theory’s of Charles Darwin.

From his theories on variation of species to his explanation of natural selection Charles Darwin has shocked the world by proving the world older than previously thought and creatures not immutable. In this present day these theories are as common belief as a simple mathematical equation such as two plus two equals four; but in the year eighteen hundred and fifty nine DarwinRead MoreDarwin’s Theory of Natural Selection and Social Darwinism Essay1179 Words   |  5 PagesCharles Darwin postulated a scientific theory, which stated that all living organisms evolved through a process of natural selection. According to Stephen Hawking, Charles Darwin claimed that the offspring of a particular species gradually evolved themselves genetically to resist the changes in the environment (573). The theory contended that the organisms could adapt to the changes in the environment through the survival of the fittest.

This book brought him great recognition as well as many violent attacks. It was written in a time in history when the people were very strong believers in the Chur ch and God. Darwin was the first to contradict their religious beliefs of Creation, and was pummeled with criticism. Although today some still disagree, his explanation of evolution through natural selection is accepted by many.

Darwin said that evolution took place by a process of natural selection or survival of the fittest. This meant that the animals and plants best suited to their surroundings survived and were able to pass on their genes to their offspring. The ones that werent best suited died off and didnt get theRead MoreCharles Darwins Theory of Evolution by Natural Selection Essay1306 Words   |  6 Pagesinformation about evolution. He met many explorers that had various ideas of their own about how man evolved. In discussion with these people, he figured out if what they were telling him was fact or fiction. This helped him to formulate his own theory. Curiosity was aroused in Darwin at a very young age. He was one of those children that are always into things, trying to find out how things work. He was especially interested in the outdoors. He was a very smart child, but his father,Read MoreCharles Darwins Theory of Evolution by Natural Selection Essay1675 Words   |  7 Pageswho had proposed a theory of evolution based on a continuous process of gradual modification due to acquired characteristics. Both Darwin and Wallace brought together a multitude of facts including the geographical distribution of organisms, comparative morphology of living organisms and their fossil precursors. They postulated that long-term environmental changes including movement of land masses and changes in climate could have served in the process of natural selection over many generationsRead MoreReconciling Darwins Theory of Natural Selection and Intelligent Design835 Words   |  4 PagesNatural selection is an important component of evolution. Natural selection occurs when some members of a population are better fit for survival and reproduction than the others in that population (Phelan 284-85, 2011). The environment in which organisms live plays a part in natural selection as well. Depending on the conditions of the environment, the organisms may pass down selected traits to their offspring. These selected traits will allow for the next generation to better adapt and survive longer
