Dawkins and the Selfish Gene: A Summary
Richard Dawkins, an English evolutionary biologist and writer, is well known for his book The Selfish Gene. Published in 1967, his book provides a distinct view on the process of natural selection. Dawkins’ controversial selfish gene theory focuses on genes as the basis for evolution. It has received much criticism, however it contributed to a new way of viewing evolution based on genes. In Dawkins and the Selfish Gene, Ed Sexton provides an explanation for Dawkins’ commonly misinterpreted gene theory.
First, he establishes the concept of selfish genes with analogies to the functions of physical things, such as human beings. “The fundamental unit of evolution is the replicator…anything which can be

In this sense, the parenting gene may risk or give up something to allow for more success of the offspring replicated gene. He compares this behavior to parenting, expressing how parents take risks in order to help protect their child. Altruism occurs between related and unrelated species, and the connection lies behind cooperation that will allow one or both parties to reap rewards. This concept is tied to the concept of the prisoner’s dilemma; where in cooperation, two individuals receive shorter sentences in prison, but if one acts selfishly, he receives reduced time and the other more time. In nature, the Tit-for-Tat strategy – where something is given in return for something received – reveals cooperation. And in these examples, Sexton illustrates Dawkins’ theory.
Opposing views to this theory include the idea that nature cannot directly affect genes, but instead their vehicles, our bodies and other organisms. Though, genes influence behavior of organisms and their environment. Sexton states: “Selection will act on entity that exists long enough for its frequency in the population to be changed.” He corresponds a gene with a behavior, then a trait, and to an organism, then questioning if it is not right to look at selection from a broader point, including more than just

So to better understand the reasoning behind man's need to be in the community it is imperative to look at nature. In the wild and brutal game of life the only measure of true success is whether genes are passed on. Like any other animal this measure of success measures man's success too. For all creatures, to survive is the chance at continuing a gene line, and it is this necessity to continue the line that is innately imbedded in man and all other creatures.
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.
Keith Henson a writer in evolutionary psychology once said that “Evolution acts slowly. Our psychological characteristics today are those that promoted reproductive success in the ancestral environment.” Evolution was first introduced by a naturalist by the name of Charles Darwin. Darwin had written an autobiography, at the age of 50, On the Origin of Species (1859) explaining how species evolve through time by natural selection; this theory became known as Darwinism. “Verlyn Klinkenborg, who writes editorials and vignettes on science and nature for the “New York Times”” (Muller 706) questions Darwin’s theory in one of his essays he wrote called Darwin at 200: The Ongoing Force of His Unconventional Idea. Both articles talk about the theory of Darwinism, but the authors’ use different writing techniques and were written in different time periods. Darwin himself writes to inform us on what the theory is, where as Klinkenborg goes on to explain why Darwinism is just a theory. Today, evolution is still a very controversial topic among many. It comes up in several topics that are discussed everyday such as in politics, religion and education.
One of the most controversial topics discussed in the world of medicine pertained to the topic of genetic engineering. Some doctors saw it as tool of world destruction, however many of them seeing it as a chance of potential cures and treatments. Charles Darwin first introduced this idea. In his first publication, The Origin of Species, he introduced the idea of survival of the fittest. He stated that evolutionary change was only possible due to the genetic variation between each generation, including the combination of different characteristics. In other words, he wrote that only those who had desirable characteristics, in terms of survival, would be able to pass down their genes. If two bred and possessed desirable characteristics, then the desirable characteristic would strengthen, modifying the genes. Darwin’s theories have been the base of many medical breakthroughs that contributed to genetic engineering. The idea soon influenced medicine, the idea of strengthening the healthy cells and isolating them from the unhealthy ones. The simple idea Darwin discovered had changed medicine as a whole. Today, doctors and scientists are able to manipulate genes in order to create new treatments and cures. Today, Darwin’s discovery changed and saved millions of lives around the world. Despite the fact that genetic engineering can have a negative impact on society, it was an important discovery due to the advancement in conventional medicine.
With his provoking work entitled The Selfish Gene, Richard Dawkins attempts to answer such questions as he proposes a shift in the evolutionary paradigm. Working through the metaphor of a "selfish gene", Dawkins constructs an evolutionary model using a gene as the fundamental unit of selection, opposed to the more commonly accepted belief of the species as the unit of selection.

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...

behavior for the benefit of other." (Recent Work on Human Altruism and Evolution) Another popularized theory by Richard Dawkins states that an individual who behaves more altruistic towards others who share its genes will tend to reproduce those genes. But since we always want something in exchange for something we did, can this truly exist, or is it just an illusion? On Jan.
Some psychologists believe that altruism stems from evolution, or the survival of the fittest. They point to examples where ants will willingly bury themselves to seal the anthill from foreign attacks, or the honeybee’s sting. That sting rips out the honeybee’s own internal organs, and has been described as “instruments of altruistic self-sacrifice. Although the individual dies, the bee’...
Charles Darwin in his book, On the Origin of Species, presents us with a theory of natural selection. This theory is his attempt at an explanation on how the world and its' species came to be the way that we know them now. Darwin writes on how through a process of millions of years, through the effects of man and the effects of nature, species have had an ongoing trial and error experiment. It is through these trials that the natural world has developed beneficial anomalies that at times seem too great to be the work of chance.
Dawkin proposed memes theory by looking at the genetic evolution process and question whether there is something that happens beside genetic evolution
The evolution theory, one of the most significant theories, laid groundwork for the study of modern biological science. This theory has lead scientists into unending debates due to lack of empirical supports. Until the mid-eighteenth century, when Charles Darwin came up with an explanation to evolution, scientists, then, began to endorse this hypothesis. In “Natural Selection,” Darwin explains the natural selection, a plausible mechanism that causes evolution, to gain approval of his cynical audience for his evolution theory. He supports his claim with numerous examples of animals and plants that have developed traits beneficial for survival. A century later, Stephen Jay Gould, influenced by Darwin’s work, supports the evolution theory with a different method. In “Evolution as Fact and Theory,” Gould, in contrast to Darwin, criticizes his detractors, the creationists who believe that every life form is the creation of a supernatural being, to reinforce the validity of the evolution theory. Gould undermines creationism by emphasizing its misused concepts of theory and popular philosophy, proving that it is not science. Besides denouncing creationism, Gould also provides theoretical examples as evidence to prove evolution is a theory. Despite their different approaches, both Darwin and Gould effectively prove the existence of evolution.
