Altruism And Natural Selection Essay

Decent Essays
The theory of natural selection has many independent lines of evidence that support its validity. Merriam Webster defines natural selection as, “The process by which plants and animals that can adapt to changes in their environment, are able to survive, and reproduce while those that cannot adapt do not survive,” illustrating Charles Darwin’s Theory of Evolution, which was heavily based on his observations of the natural world. Though there are arguments against Darwin’s findings, as with all theories, there are more abundant and compelling forms of evidence in his theory’s support. There are many who criticize Darwin’s theory of natural selection. The theory of natural selection was questioned by the understanding of some critics to believe …show more content…
Specimen adapt to their environment to survive and continue to pass on genetic material. Altruism is a survival behavior is found in more than one species and the reasoning develops on the basis of biological expansion and the evolutionary need for a species to thrive in order to progress. Although altruism challenged Darwin, a deeper look into the reasoning reveals a similar interest between altruism and natural selection. Survival of the fittest is a selfish trait, but altruism can be applied to survival of a gene. This is known as kin selection, and chances of survival are increased if the family works together. Families share genes, so it would be in the best interest to protect relatives so there could be a higher chance of one of the genes surviving to the next generation; therefore, a part of the individual’s genes survive. Altruism obscurely benefits the survival of the individual and aids in the passing on of genes, which is part of the definition of natural selection. In the mid twentieth century, “Hamilton was the first to clearly sound this central theme of the new Darwinian paradigm: looking at survival from the gene’s point of view,” (Wright) and in this, altruism fits harmoniously with Darwin’s theory of natural selection through the subsection of kin …show more content…

    “Evolution as Fact and Theory” by Stephan Jay Gould outlines the constant taxing debate over evolution among creationists and evolutionists. He outlines the major issues that fuel the dispute and provides the logical and scientific approach to evolution for a clear argument against the claims of creationists. He firstly, provides a thorough explanation of the misconceptions of the definitions; “theory” and “Fact’. In the common vernacular a fact may be perceived as undeniable information with absolute certainty. (gould)…

    Here many creationists would object that all humans have been created by a higher power and dismiss evolution as nonsense. Sonder suggests that an abundant amount of Darwin’s theory is supported by the reputable findings of Gregor Mendel, a monk who discovered evidence that humans share some genetic patterns with a variety of other organisms (12). Edward J. Larson’s work in “Summer for the Gods” allows his audience a great deal of information on the matter of the comparing evolution and creationism. Many Americans, despite apparent evidence…

    Explaining Evolution Evolution has always been a relevant topic, whether being explained in learning environments or thoroughly investigated by scientists, why is it so important? Evolution tells the story of how humans, as well as other species, came to be. The articles “12 Examples of Evolution Today” by Erin Brodwin and “A Possible Break in One of Evolution’s Biggest Mysteries” by Peter Brannen are both compelling with the information they provide, and contain insights into the world of evolution. Brannen’s article is specifically focused on the whale and studying the barnacles on their bodies to gain more knowledge on the story of their evolution, whereas Brodwin’s article is broader and shares information on different species that evolved…

    You could likewise advance this contention with the illustration of Kin Selection given by Samir Okasha in his article titled "Natural Altruism" from the Stanford Encyclopedia of Philosophy where he portrays the marvel of organisms that will probably help different living beings that are more comparative or identified with them. Individuals will probably act altruistically towards relatives or even individuals of the similar race. The more comparative individuals are the more probable they are to act charitably toward one another, a choice in light of compassion and hereditary qualities. The closeness in the middle of race and family can bring about a person to act unselfishly to save its hereditary…

    “It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change” – Charles Darwin. Evolution is “the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth”. The theory of evolution has become one of the most controversial topics in science because of how the public reacts to the contents of the theory. The theory is controversial because it posses the debate of whether God or a supreme being played a role in the process of evolution or that humans have evolved naturally over time. Many opponents of the theory argue that science is a knowledge that can only be repeated, demonstrated, and observed and evolution can only be believed in.…

    Evolution is a polarizing subject that some people may choose to regard it as fact while others may choose to regard it as a mere theory. Most people, including scientists believe that evolution is a fact because the evidence supporting it is very strong. However, others are reluctant to believe that evolution has happened because it may contradicts their holy beliefs and because no one has seen it happen. Evolution is a theory or a fact only to the extent that people are willing to accept it a theory or a fact. The Scopes Trial in 1925 sheds some light on the attitudes that people once had towards evolution.…

    In the period from 1860-1900, Darwin developed his theory of natural selection. Natural selection was the idea that a dominant species would overcome all the rest. This sparked many ideas and philosophies, such as a weakening in the church, the rise of Social Darwinism, and a surge of new ideas and thought. The church had always been the lead in the sciences of the day, but when scientists started to challenge the church, their strength began to falter.…

    In the essay, “Evolution as Fact and Theory,” Stephen Gould defenses Charles Darwin’s theory of Evolution over the beliefs of creationist on God creating all organisms in the world. To further his support, he states his three arguments which are observational evidence, the imperfection of nature, and transitions found in fossil records to demonstrate that even though evolution is just a theory, there are plentiful evidence of facts that supports it. The essay was not just about justifying the theory of evolution to the creationist but also to reject the ideas of blindfolded views on scientific creationism. Throughout the essay, Gould acknowledges many of the major perspectives of the scientific world to support the theory of evolution that…

    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…
