Essay on Charles Darwins Theory of Evolution by Natural...

Charles Darwins theory of evolution centres on the idea that species compete to survive, and favorable characteristics are passed on from one generation to the next. 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 the chance to reproduce. Animals and plants had to change or evolve due to environmental pressures. Over millions of years the conditions on the Earth have changed tremendously, the environmental conditions we have now are very†¦show more content†¦Darwin noted four things from his observations: 1. All organisms produce an abundance of offspring, many more than is necessary 2. There is a fairly constant population size over time for any particular organism 3. Within a species there is a wide range of features, due to different alleles 4. Some variations are passed on and inherited by the offspring From these Darwin decided that all organisms struggle for survival and so have to produce many offspring to ensure that some do survive. He also concluded that for a species to survive, the best (or fittest) of them must survive long enough to reproduce and pass on their genes. It has three essential parts: It is possible for the DNA of an organism to occasionally change, or mutate. A mutation changes the DNA of an organism in a way that affects its offspring, either immediately or several generations down the line. The change brought about by a mutation is either beneficial, harmful or neutral. If the change is harmful, and then it is unlikely that the offspring will survive to reproduce, so the mutation dies out and goes nowhere. If the change is beneficial, then it is likely that the offspring will do better than other offspring and so will reproduce more. Through reproduction, the beneficial mutation spreads.

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 Cha rles 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 MoreCharles Darwins Theory of Evolution by Natural Selection Essay1286 Words   |  6 Pages When the name Charles Darwin is uttered, an immediate association brings about the concept of Evolution. Although he was not the first to discover this phenomenon, he was the first to explain it. In his book, The Origin of Species, Darwin discusses evolution- through variation, why it occurs, the struggle for existence, natural selection, the geological record, and several other topics. This book brought him great recognition as well as many violent attacks. It was written inRead MoreCharles Darwins Theory of Evolution by Natural Selection Essay1306 Words   |  6 Pagesexplorers have made attempts to try to answer this question. Charles Darwin was one of these people. Darwin led a full life of exploration, and during these adventures, he accumulated much information 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.

His name is synonymous with the debate that continues to swirl around the theory of evolution, a theory that deeply shook the Western view of humanity and its place in the world. We tend to speak simply of the theory of evolution, leaving off the explanatory phrase, quot;through natural selection.quot; At most, perhaps, the general public has heardRead MoreCharles Darwins Theory of Evolution by Natural Selection Essay1793 Words   |  8 Pageswas Charles Darwin. Darwin was the most accomplished of these men because he was able to put forth a logical conjecture that was based upon facts and observations. This theory, for a short time, was able to end the feud among educated men because many now put their trust in this new â€Å"theory of evolution†. Unfortunately, this revolutionary new theory threatened the religious beliefs about creation and soon a new rivalry emerged between the creationists and evolutionists.

Darwin’s theory has had a great impact on the world today. It has caused many debates between religious authorities and those from the scientific community. This theory prompted individuals to think about the origin of life in the universe. What distinguishes Charles Darwin from the others is the fact that he collected and provided substantial evidences and he related various branches of science such as geology, botany and biology, which helped, validateRead 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 MoreLamarcks Influence Upon Charles Darwins Theory of Evolution by Natural Selection1928 Words   |  8 Pagesideas on the theory of evolution. Some simply take our existence for granted, others prefer to explain all evolution in terms of the bible and the presence of a God. However, there are those who have researched the topic of evolution and have offered an explanation as to where a species comes from and how they evolved in the manner that they did. This type of science has been studied for a very long time, and one of the most famous minds in the field of evolution was a man named Charles Darwin.Read MoreCharles Darwin s Theory Of Evolution1173 Words   |  5 Pages It is time to start believing. Evolutionary theories were first proposed by Charles Darwin in the 19th century, and 150 years later, these ideas are still being studied and proven today. Charles Darwin set the basis for these discoveries. Natural Selection and survival of the fittest are two examples of evolution. Charles Darwin once exclaimed, â€Å"It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.† This
