Theories Of Evolution: The Paradox Of Anthropocentrism

Improved Essays
The Paradox of Anthropocentrism In the simplest possible definition, the word evolution is understood as change over time. The notion of evolution, however, more complicated than just the meaning of the word. Conceptually, evolution has dichotomized exceptionally clearly. To the scientific community, evolution is a clear reference to the work and theories completed by Charles Darwin throughout the span of his lifetime, and the modern day knowledge of the process in which organisms develop specific desirable traits in response to altered environments. However, evolution 's third definition draws the line between scientific and non-scientific understandings. The Merriam-Webster dictionary defines evolution as "a process of continuous change …show more content…
When Darwin wrote about evolution, he spoke specifically of descent of modification, through the process of natural selection. The theory of evolution states that for natural selection to occur within a species, several factors must be applied. Firstly, in a given population, more organisms must be born than can survive. Secondly, in the population, there must be variety in the traits found in individual organisms. Thirdly, these traits must be heritable, and can be passed down from the parent organisms to the offspring. Lastly, the population must only have access to limited resources in the environment, causing them to compete with each other for the resources. When these four factors occur in the natural world simultaneously, natural selection occurs as the organisms with the traits most useful for survival and mate selection inevitably have the highest rates of survival. The traits that helped the organisms survive will pass on to their offspring, and the organisms with less beneficial traits will not produce as many offspring. After multiple generations of this process of differential reproduction occurring, the population will have modified so that the desirable trait is found in most of the organisms. This development of preferential traits having high representation in each new generation is the basis of Darwin 's theory …show more content…
In his book A Wonderful Life: The Burgess Shale and the Nature of History, Stephen Jay Gould discusses the progression of man as the paradigm of this dichotomy. The progression of man the most common image associated with evolution; where a linear sequence portrays an ape gradually developing into modern man. Yet, Gould argues that this assessment of evolution is deeply flawed, and that evolution can be best represented by non-linear imagery. Instead of a ladder leading straight from apes to humans, a bush that branches outwards with each modification in species variety would better depict how evolution works (Gould 15). Egocentrism has created a belief that evolution focuses on man exclusively. If a bush illustrated evolution, then the emphasis of evolution would be on variety, and not on progress. Gould accentuates that evolution at its core should reflect species with large amounts of variation, rather than reflecting modern species as more advanced than their ancestors (Gould 16). The author states that the reasoning behind this flawed interpretation that discounts variety in evolution as "because we try to extract a single line of advance from the true topology of copious branching. In this misguided effort, we are inevitably drawn to bushes so near the brink of total annihilation that they retain only one surviving twig. We then view this twig as the acme of upward achievement,

    Charles Darwin’s theory of evolution by natural selection is quite simple but often misunderstood (Understanding Evolution). The easiest way to understand this idea is by realizing what an organism needs to survive. Many traits of different organisms like animals, insects, and even humans have all evolved and are still evolving to be able to fulfill their essential needs. The dominant gene is what is passed down to an organism’s offspring. This gene could change a trait that helps an organism to survive (Dorken et al. 2016).…

    Jerry Coynes', Why Evolution is True, had the instinctive capacity to utilize science as the perfect means to force me to question everything I had been taught about evolution. He presents and explains his ideas about evolution systematically and in detail. While reading each chapter, I was able to reflect on my personal evaluation of “Why Evolution is True” based on Jerry Coyne’s words and ideas. The idea of evolution is met with much defiance for several reasons.…

    There are four parts to natural selection and they are genetic variation, overproduction of offspring, struggle for existence, differential survival and reproduction. My Biology class did another lab called “Origami Bird Lab.”. In this lab we started with three birds made out of paper and straws they all had the same width, circumference, and length. We flew the three birds and whichever bird flew farther bred the next generation of birds. The first offspring of every generation had no mutations while the other two birds in each generation had mutations that were determined by a coin and die.…

    Introduction Charles Darwin is famous for his book, The Origin of Species, where he proposed that evolutionary change in populations is due to natural selection. His idea was that of survival of the fittest. In other words, the species with superior traits would have more of a likelihood to live, and then breed more offspring. Slowly, more and more of the species with the superior traits will survive and multiply. But what is it that gives these species the better survival trait, and allows evolution to occur?…

    Evolution is how modern living organisms are related to ancient ones. Organisms have diversified and modified through ages and old one became extinct. According to Charles Darwin, all species have common ancestors. This means that, for instance, whales and dogs are related to each other by an old ancestor. Indeed, many organisms have common traits and characteristics, but this still doesn't mean that they are related.…

    Charles Darwin in his The Descent of Man and Karl Marx in his The Communist Manifesto suggest similar understandings of progress. For Darwin, progress manifests itself in natural selection, often known as “survival of the fittest,” where fittest refers to organisms that can survive and reproduce successfully and not to the most physically fit. Marx realizes that “the history of all hitherto existing society is the history of class struggle,” and thus understands progress as the removal of class struggle and the movement towards the making of an equal society (Marx 62). Essentially, both Darwin and Marx understand progress as an evolution, a change towards something which is more developed and arguably better than its previous form. This understanding…

    Evolution is a change in populations over time. It is the population that evolves, rather than an individual. There are four mechanisms of evolution: mutation, gene flow, genetic drift, and natural selection. There were multiple contributors to the ideas of evolution, including Charles Darwin and Alfred Wallace. To begin with, mutations cause genetic variation.…

    It is also true that many of the living things on earth now were not all existing during the past with dinosaurs, such as, birds and mammals. Since, dinosaurs don’t exist in the present time and birds do, then it must be correct that all life on earth evolved from previous ancestors such as birds from dinosaurs and humans from apes. On that note, Gould’s argument on evidences from the fossil records suggests one of the most famous example of fossil transition called Archaeopteryx. It is a genus of early bird that has a combination of feathers and structures of a bird with features such as teeth, pony tail, and legs of a small coelurosaur dinosaur. Additionally his third argument outshines the beliefs of creationist over the evolutionist because it questions that if God created human species long time ago, then why God added more modern features in a chronological sequence such as reducing face, teeth, and etc. to humans.…

    Darwin’s idea has been born as an answer to questions in biology. He as the father of evolution contributed the most to our modern science. Even in this present his theories such as natural selection is still used, like a simple mathematical equation. We all know that two plus two equal four, however, did we ever question why? Taking this in consideration, his natural selection theory was based on idea:” Survival of the Fittest”.…

    Two vital components of evolution are an organism’s ability to survive and reproduce. Differences in an individual may be random, but the ability of an organism to survive and reproduce is not up to chance. Inherited traits more suited for a particular environment will allow individuals to thrive and flourish. Resources are finite and natural selection occurs because individuals are forced to compete for resources in order to stay alive. The ability to survive and reproduce goes hand in hand as shown in the following example.…

    “It is no the strongest of species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.” This quote was once said by the father of evolution himself, Charles Darwin who spent his life’s work on learning all he can about evolution. In the world we live in all organisms change, and were not the same thousands of years ago as they are today. There are two main theories to this process; scientific theory and religious theory.…

    Understanding how humans and other organisms have evolved is fascinating. Charles Darwin was the individual who developed the theory of natural selection. Natural selection is “the process by which species become better adapted to their local environments” (Witz BW 2004). Darwin arrived at this statement by observing the biological structures of organisms, formulating a hypothesis, testing his hypothesis and then using the evidence he discovered to support his…
