Darwin 's Theory Of Evolution

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 he'd 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 Darwin's Theory of Natural Selection taken directly from the two chapters concerning it in his book

Over time, different species learn to adapt to their living environment in order to survive. If a genetic change of a characteristic is passed down through generations, a formation of a new species occurs (G, Linstead et. al., 2012). A variation to the characteristic of an individual can increase its survival and this provides more opportunities to reproduce. When the individual reproduces, the offspring benefit in result of the heritable genes and eventually through generations, the variants will be spread throughout the entire population (Montgomery, 2009). Charles Darwin’s theory of natural selection can be supported through both fossils and homologous structures.

Although up into the nineteenth century it was common belief that a divine being created life, life has evolved since its first appearance about 3.8 billion years ago. Darwin claimed in his book, On the Origins of Species published in 1859, because “ ...many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existence…” small variations that occur in the mutation of genes and genetic recombination during reproduction. Some of these variations are bound to be better suited to their environment and will succeed. Those that are less favorable are bound to fail. This is a process called natural selection. This genetic advantage increases the likelihood that the

Darwin's theory of evolution is based on five key observations and inferences drawn from them. These observations and inferences says that Populations remain roughly the same size, but sometimes variations increases or decreases. Food resources are also limited, but most of the time it remains constant. From these three observations it can be guessed that every individual has to compete with each other to survive due to large population. Much of this variation is heritable.

Charles Darwin came up with the theory of “Natural Selection,” which explained how animals produce offspring that will replace them. The theory of “Natural Selection” also fits the phrase “survival of the fit,” which became (or evolved - how fitting) “survival of the fittest.” Basically, animals eventually adapt to their environments through evolution. The evolved organisms, or the “fittest,” will end up surviving better and longer than those that are not as adapted.

Charles Darwin’s book “The origin of species” was undeniably a very controversial book at the time of its release. Published in 1958, when the world was still seen as a creation of someone with supernatural abilities, this book caused enormous backlash. One great cause of turmoil was from the Catholic Church, which was insisting that Darwin was trying to disprove the influence of a supernatural creator, which, in their opinion was “god.” Although most of the public perceived Darwin’s beliefs as absurd and inordinate, most scientists agreed with Darwin’s findings. Darwin’s discoveries were of such powerful relevance, that it changed most previously held beliefs. Nonetheless there are still multiple ideas, more or less widespread, which state

The most well-known summarization for what evolution is, is a change in genetic makeup (phenotype makeup) of a population over time; or a change in allele frequencies in a population over time (College Biology, 2014, p. 513). Darwin’s theory of natural selection says that organisms have great potential fertility, natural resources are very limited, variation in phenotypes exists among individuals within a species, natural populations naturally remain constant and consistent in size, and traits (an observable or measurable characteristic) that an organism holds are heritable (College Biology, 2014 p. 486-489).

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.

According to American heritage dictionary of student science Evolution is defined as “Change in the genetic composition of a population during successive generations, often resulting in the development of new species”. Evolution to me is a subject that has more questions than answers. Charles Darwin’s theory of evolution was that he believed that all living organisms came from a common universal ancestor. Darwin’s studies suggests for example humans frogs fish and cats called all be traced back in a timeline to a common ancestor in a tree of life because we all have small similarities such as legs and shoulders. In contrary however, how could all of us be related if we all live and survive under different circumstances and situations? Evolution is also known to have changed in time in a population of species through natural selection.

This is the study of different body structures of different species to know how they are adapted to different tasks and to understand the adapted changes that have occurred through the life dating from their ancestry to date. In Darwin’s study he tries to explain that different body study structures that one species can look the same have risen to perform different functions. For example birds and insects have wings but they use them differently. The birds use them to fly and to cool their bodies and insects only use them to fly. Some birds have wings but can’t fly for example the ostrich thus the homologous structures are different but have risen to perform similar functions (Thaler, D, 1999).

When Charles Darwin formulated his Theory of Evolution by Natural Selection, he had adopted some assumed premises. The most important of all these premises was that all biological organisms have an innate imperative for survival, if not solely for themselves as individuals, then for their offspring, and ultimately, their species. Regardless of whether or not these biological entities are even aware of this “will to live and proliferate,” it is assumed to not only exist in all living things, but also to be their ultimate goal. Man, Homo sapien, a biological organism, would be expected to have the very same primary goal towards survival, yet, often times it seems man has a more important agenda– towards personal gain.

Charles Darwin is remembered for his theory of evolution. Much controversy surrounds Darwin 's theory. Questions abound. Is evolution a four billion year old process, creating life forms primarily at random but each shaped by an ever-changing and complex environment, that has resulted in all of the wondrous life forms that surround us? Or are all of those beautiful elements of our nature, along with the vastness and majesty of the entire universe, a creation of an intellect of vast intelligence and empathy, one far greater than anyone can imagine? Questions are being asked. Did man really evolve from an ape? Or, is it that both man and ape are, along with all of the other flora and fauna, creations of a giant intellect that first perceived

Charles Darwin’s Theory of Evolution is the most successful theory of it’s kind. Darwin’s idea of Natural Selection has found success not just in the organic world, but also in human society. This is no coincidence. After Darwin’s Beagle voyage, he returned to England during the Industrial Revolution. As a man of wealth, Darwin acted as a first-hand witness to the societal changes occurring around him. The Industrial Revolution, along with the corresponding economic theories played a large role in influencing Darwin’s theory of evolution.

Countless scientists spent their lives working on a succinct theory of evolution, but none found as great of popularity and success as Charles Darwin. Using his concept of Natural Selection, Darwin managed to explain evolution in not just the organic world, but also in humans. The fact that Darwin’s theory transfers so easily to human society is no coincidence. After Darwin’s Beagle voyage, he returned to England during the Industrial Revolution. As a man of wealth, Darwin acted as a first-hand witness to the societal changes occurring around him. The Industrial Revolution, along with the corresponding economic theories of Adam Smith and Thomas Malthus, influenced Darwin’s theory of evolution as well as helped make his theory popular among social elitists.

Charles Darwin was an English naturalist and geologist, he was known greater for his contributions for the evolution theory. Darwin wrote a book in 1859 it was published and became the greatest and well known book. The name of the book was “On the Origin of Species”. In the book he wrote about his theory of evolution by natural selection, he discovered how the process of how organisms change as time goes on. Changes in traits and the organism’s physical behavior. Darwin believe change happens slowly over time. This was a quote that , Darwin wrote, "…Natural selection acts only by taking advantage of slight successive variations; she can never take a great and sudden leap, but must advance by short and sure, though slow steps"(Charles Darwin, 1859).
