A lot of conflicts, debates, and even fights are about a theory by a scientist called Charles Darwin. This theory is the theory of evolution, which is viewed as the most important and the most debated theory of all-time. This theory changed science forever. However, this theory is not believed by everyone and some people even say that Charles Darwin, who formulated this theory, even said it was wrong before he died. However, this theory is not all wrong and useless, because natural selection, which is the mechanism of this theory, is believed in by most people and scientist. Although natural selection is believed in by most people and scientist, there is an argument that natural selection is a random process, however natural selection is definitely not a random process.
Natural selection is a random process is a misconception, because natural selection is not a random process. Natural selection is not a random process for two reasons. The first one is that the genetic variation that occurs in a population because of mutation is random, but selection acts on that variation in a very non-random way. Genetic variants that aid survival and reproduction are much more likely to become common than variants that don't. As the organisms that have genetic variants that aid survival and reproduction will definitely survive, reproduce, and will not die. While the organisms with no genetic variants that aid survival and reproduction will definitely not survive, reproduce, and will die. This means that the organisms with theses genetic variants will clearly outnumber the other organisms; this is the first reasons will natural selection is not a random process. The second one is that although the genetic variation on which natural selection act...

...lection acts may occur randomly, but natural selection itself is not random at all. As the survival and reproductive success of an individual is directly related to the ways its inherited traits function in the context of its local environment. The third one is that as explained by the theory of evolution, individuals with characteristics which increase their probability of survival will have more opportunities to reproduce and their offspring will also benefit from these heritable advantageous characteristics. The last one is the evidence from the biological science and the natural world, which include the Galapagos finches, the peppered moths, and the pesticide-resistant insects. All these reasons definitely prove the misconception that natural selection is a random process wrong, and provide strong evidences that natural process is clearly not a random process.
In Charles Darwin’s life he had helped make a significant advancement in the way mankind viewed the world. With his observations, he played a part in shifting the model of evolution into his peers’ minds. Darwin’s theory on natural selection impacted the areas of science and religion because it questioned and challenged the Bible; and anything that challenged the Bible in Darwin’s era was sure to create contention with the church. Members of the Church took offense to Darwin’s Origins of Species because it unswervingly contradicted the teachings of the book of Genesis in the Bible. (Zhao, 2009) Natural selection changed the way people thought. Where the Bible teaches that “all organisms have been in an unchanging state since the great flood, and that everything twas molded in God’s will.” (Zhao, 2009) Darwin’s geological journey to the Galapagos Islands is where he was first able to get the observations he needed to prove how various species change over t...
Charles Darwin, the Father of Evolution, was a British scientist who laid the foundations of the theory of evolution, transforming the thinking of the entire world about the living things around us (Charles Darwin (1809 – 1882)). After working on his theory for nearly 20 years, he published On the Origin of Species by Means of Natural Selection in 1859. As soon as the book was released, the controversy began with each sides gaining followers until the climax on July 10, 1925. The idea that animals could “evolve” and change into new species, including humans, was one that challenged not only how people thought about the natural world, but challenged the story of the creation from the Bible itself. Even though Darwin himself never said that humans “evolved” from apes, everyone took it as a logical extension of his new theory. It went against the idea of argument for design that had unified theology and science for decades (Moran 5). This new threat to Christianity and the social culture of the time was one that would transform state laws on their educational curriculum.
Darwin describes natural selection as daily and that natural selection happens everywhere in the world. Whatever is weak is diminished and the good variations are kept for the next generations.
There is a lot of controversy regarding the use of technologies that allow sex selection. Modern science allows parents to choose the sex of their future child. Although this could be an effective way to determine genetic disorders, I do not support screening to be used solely for sex selection as this can lead to social inequality and gender bias.
Besides, I feel that the idea of Natural Selection is really similar to the teaching of Buddha. “This preservation of favorable variations and the rejection of injurious variation, I call Natural Selection” Darwin explained the definition of Natural Selection. It means that all creatures should keep the good things and destroy the bad things in order to survive in the world.
Darwin's theory of Evolution have been known by the world for many centuries. Even so, not all scientists supp...
Charles Darwin’s theory of natural selection explains the general laws by which any given species transforms into other varieties and species. Darwin extends the application of his theory to the entire hierarchy of classification and states that all forms of life have descended from one incredibly remote ancestor. The process of natural selection entails the divergence of character of specific varieties and the subsequent classification of once-related living forms as distinct entities on one or many levels of classification. The process occurs as a species varies slightly over the course of numerous generations. Through inheritance, natural selection preserves each variation that proves advantageous to that species in its present circumstances of living, which include its interaction with closely related species in the “struggle for existence” (Darwin 62).
Anyone with even a moderate background in science has heard of Charles Darwin and his theory of evolution. Since the publishing of his book On the Origin of Species by Means of Natural Selection in 1859, Darwin’s ideas have been debated by everyone from scientists to theologians to ordinary lay-people. Today, though there is still severe opposition, evolution is regarded as fact by most of the scientific community and Darwin’s book remains one of the most influential ever written.
Randomization, in the form of mutations, provides genetic variation. Evolution itself is not entirely a random process, but the mutations that have appeared throughout history are. Because of this, one would argue that with the summation of many mutations over time, evolution would inevitably create more randomization within the system resulting in an increase in disorder. In an isolated system, the overall entropy would undoubtedly increase following a series of mutations. Because of natural selection (the idea that an organism that is better suited to its environment will survive and produce more offspring than those organisms who are not), it can be said that chance mutations are not the only driving force behind evolution, thus evolution is not entirely a spontaneous process (Williams,
Evolution is the reason for many different species and their existence. Evolution proves that there is much more to the world than the human can see. Charles Darwin had looked into the eye of the storm, and found something revolutionary. His research has changed and reshaped science in it’s own very existence; changing how scientists see their works. Charles created a new way of thinking, and proven that there is always an alternate reason why something is the way it is, and how it became that way, not to mention he constructed against religion that proves itself to be wrong. Everything has a reason, and evolution has made that reason clear to us, through Darwin’s works.”Charles Darwin is best known for his work as a naturalist, developing a theory of evolution to explain biological change.”
Charles Darwin has five parts to his theory of natural selection, firstly the “Geometric increase” which claims that “all living things reproduce in great numbers”, meaning that species may survive but not all will survive because, the resources used for survival for instance ,food will not be enough for all living things. “The struggle for existence” because there is a limited number of resources and can only sustain some and not all, not all living things will survive, however the question lies in which living being will survive?. “Variation” is the third part of natural selection which claims that within those living things there are variations within them that will determine whic...
Natural selection is driven by reproductive success. If a species can reproduce and its offspring survive than any traits in its genotype that assisted in its survival will be passed on from generation to generation and ensure that the species will live on. Around the time the Theory of Evolution was suggested, society was very religious and very pressed on the Theory of Creation, so the publication of Darwin’s The Origin of Species by Means of Natural Selection caused a lot of controversy. Darwin gave the world strong evidence that natural selection and evolution played a major role in the development of the species that we see today. Of course natural selection is not the only process driving evolution.
However, mutation is random in the evolution, and provides raw material for natural selection, genetic drift, and gene flow to work on.... ... middle of paper ... ... Evolution is an ongoing process and the evolution is made up of many different processes. It allows species to become what they are, how they act, and what they will become.
Many scientists in the past, such as Aristotle and Plato, believed that there were no changes in populations; however, other scientists, such as Darwin and Wallace, arose and argued that species inherit heritable traits from common ancestors and environmental forces drives out certain heritable traits that makes the species better suited to survive or be more “fit” for that environment. Therefore, species do change over a period of time and they were able to support their theory by showing that evolution does occur. There were four basic mechanisms of evolution in their theory: mutation, migration, genetic drift, and natural selection. Natural selection is the gradual process by which heritable traits that makes it more likely for an organism to survive and successfully reproduce increases, whereas there is a decline in those who do have those beneficial heritable traits (Natural Selection). For example, there is a decrease in rain which causes a drought in the finches’ environment. The seeds in the finches’ environment would not be soft enough for the smaller and weaker beak finches to break; therefore, they cannot compete with the larger and stronger beak finches for food. The larger and stronger beak finches has a heritable trait that helps them survive and reproduce better than others for that particular environment which makes them categorized under natural selection (Freeman, 2002).
Natural selection is based on the concept “survival of the fittest” where the most favourable individual best suited in the environment survive and pass on their genes for the next generation. Those individual who are less suited to the environment will die.
