Summary Of The Selfish Gene By Richard Dawkins
Long before Dawkins become known as an atheist, he did his best to shape what we know as the theory of evolution. With his book, the selfish gene, he did just that. A very popular book about evolution, The Selfish Gene was written by Richard Dawkins and first published in 1976. It has since been updated and reprinted many times after. While there are many books on evolution, ones that are good are rare! This book is well written, with great use of analogies, and metaphors making it suited for a wide audience. He uses these to help explain the exciting new discoveries and theories that were being made during the time. While the metaphor Dawkins chose to use to explain his thoughts was a great success it almost seemed to overpower peoples understanding …show more content…
This is what some people like to use as an argument against this theory, but altruism could be seen as one of the foremost consequences of his theory of the selfish gene. Altruism is when animals lower their own chances of reproducing in order to help a sibling raise its chances. In some cases animals are even born sterile. If by being born sterile they are bound to helping their siblings pass on shared genes, this can be seen as the ultimate evolutionary sacrifice all in the name of their genes. Being that an organism that cannot reproduce is seen as being evolutionary unfit then the only logical and provable explanation for this is the theory of the selfish gene. Now let’s think back, Evolution can be defined as the differential survival and reproduction of genes due to a difference in a phenotype. This makes it especially challenging when trying to explain why there can be an increase in a trait that would lead to an increase in success of another while not himself. The idea of selfish selection does just this. It says that by helping a sibling reproduce an individual will help facilitate the passing of genes that they share, thus helping some of its own genes pass on. This is in part due to closely related individuals sharing an amount of the same genes. While the reasons can be sometimes debated for a trait to be continued on to the next generations, one thing we know is it must have some form of …show more content…
One of the more extreme examples that was mentioned in his book was Euscocial animals. This is when there is cooperative brood, overlapping generations, and separate breeding and non-breeding casts. A good example would be the haplodiploid hymenopterans. This would include animals like wasps, bees, and ants. In this particular species the fertilized eggs will usually develop into females (Diploid) while the unfertilized eggs will become males (haploid). This will help strengthen the relationship between the females of the colony but does come at a cost. The best way to explain altruisms existence might be to think of it this way, at its underlying level it’s not truly altruistic but rather a selfish act. Think about this, that means when an individual acts in a way that is altruistic, in reality the “selfish” genes are wanting to help their own genes in some way move forward, usually due to the other being a relative. The theory falls on the fact that if they are closely related it is more likely they have the same genes and thus if they help them in passing their genes on they are in turn helping their own genes in a

    This is an awesome book. It describes the outlook of biology not only through the eyes of faith, but from a Christian theistic point of view. In Biology through the Eyes of Faith, it explains the difference between a scientist’s perception of nature oppose to a Christian’s perception. Scientists say the world evolved which conflicts with the theistic view, which says the world came about through the creator God.…

    This separation of the river is described as a gradual change in which species came into their beings, which took place over a long period of time. Dawkins mentions in Chapter one that the river that he is referring to is that of DNA, “flowing through time” (Dawkins 4). He describes the river as being full of information and instruction on evolving, an abstract manual on the creation of species. With this being said, it can be seen that Chapter 1 and 3 are complements of each other and are able to support points made in each chapter. Evolution is gradual, as discussed in Chapter 1, further solidified in Chapter 3. Each generation of organisms is a sieve against which replicated and mutated genes are tested, a process that is not only gradual, but one that happens over time. Organisms become better and better as time goes on and are able to build off of what has happened in species before them. “Ancestors are rare, descendants are common,” meaning that good genes make successful organisms, which perpetuate good genes themselves (Dawkins…

    In this lab simulation, we studied the different factors that go into natural selection. These factors were things such as: fertility, the complexity of genes, the use of natural selection versus not using it, and the rate of mutation. All of these things would then affect the amount of generations it would take to get the “target phrase.” This target phrase was used as a tool to understand the complexity of some genes compared to the simplicity of others. The first chapter in Dawkins’ book, “The Blind Watchmaker,” correlates the most when it comes to what we studied in the lab. In the first chapter, he describes that complex things such as animals must have been made by design. However, he also explains that this designer is…

    One of her most intriguing essays is that of Darwinism. Darwinism is one of the most widely admired and taboo-bounded idols of this age and time. To say that Robinson had a difficult task writing against it is an understatement. However, she does so with great reason and imagination. She provides firsthand evidence and realistic arguments that is very unique in this time.…

    In E.O. Wilson’s In Search of Nature, Altruism in regards to nature, whether is be human or animalistic, is explored through sociobiology. As Wilson compares the societies of animals and humans to further understand the inheritance of social behaviors, he notably credits altruistic suicide as the ultimate act of courage despite it’s probability to disappear over time. Consequently, Wilson’s use of sociobiology to understand altruism creates hierarchal standards for sacrifice that humanity’s conception of altruism will challenge as time progresses.…

    Although the Darwinian evolution theory came out 150 years ago when it was first introduced in On the Origin of Species in 1859, nowadays there are still many people who firmly believe in the creationism, even some who are well educated. In chapter three of River Out of Eden Richard Dawkins brings out this situation and refutes creationism by citing scientific experiments, and finally he points out that gradualism is a principle of the evolution nature world, one that becomes indispensable when one is trying to explain complex phenomena.…

    In the text Twenty Questions by G Lee Bowie, I chose the chapter “Why Shouldn’t I Be Selfish”? In that chapter the two selections that were chosen were The Selfish Gene by Richard Dawkins and The Virtue of Selfishness by Ayn Rand. The two discuss and give examples of how selfishness is simply for survival and how being selfish can benefit that individual. The term selfishness stated by Ayn Rand is defined as “concern with one’s own interest” (525). In both selections of the chapter both philosophers compared how ones selfish action is based on the question, who benefits from it? Based off of both selections “The Selfish Gene” and “The Virtue of Selfishness” it can be agreed that when one is selfish he thinks of only the benefits he gain from it and not his rival.…

    He solely bases his beliefs on the quantity of evidence held by each side, using scientific evidence when regarding evolution and biblical literalism when regarding creationism. Dawkins from his statement concludes that based on his studies, all the evidence points towards evolution, implying that the Bible or any other religious book or testament is not a sufficient amount of data to conclude that the belief that life was created by a divine being is legitimate. Furthermore, Dawkins’ argument is captivating by distinctly claiming that he believes in one side over the other, averting from flaw of the “Integration” model, where science and religion can be basically unified as if they were in the same field of study. Additionally, Dawkins mentions the lack of evidence creationism has which can be compared to a film in which a character had the same problem,…

    Society in general would help one in need to relieve stress or because it is a good thing or a kind thing to do for someone (Cherry, n.d). Cherry (n.d), show that people do behave altruistic for selfish reason. However, it is possible for altruism to exist in this world (Cherry, n.d). When looking at the biological reason, people usually only help family members because they have to since it’s their own family. People should always help their family because they are blood relatives and it is the right thing to do. As to the societies friends, people tend to not help them often because friends are not blood related and people do not have to help those friends. This shows that people can be both selfish and altruistic, when helping others. This clearly shows that these acts can co-exist in the world, where people help they those in need with the potential of being selfish. Wilson (2015), found that humans were not the only species to be altruistic, but as well animals. A mother lion would risk her life to save her babies because it is imperative for any parent to protect their young so that they can pass on their genes. While this happens, the babies would carry on their mother’s genes and become altruistic lions for their future family (Wilson, 2015). This shows that animals can be altruistic to benefit their family's kin…

    Many individuals recognize Charles Darwin as the beginner of this way of thinking. Darwin’s theory is that populations are in competition with each other for natural resources; in this struggle to survive, the environment makes a selection known as “natural selection.” In this process, Darwin describes how the weakest individuals, because of their natural characteristic, do not survive. Only the individuals who are strong and adaptable survive and transmit the genes to the offspring. Common sense seems to dictate that his idea justifies, directly or indirectly, acts of selfishness, racism, and violence.…

    By definition, natural selection theory is whereby the organisms that have adapted well to the environment can survive even during the times of scarcity and have offspring. The theory involves both competition and cooperation. According to Darwin, competition and cooperation are related to power such that, in life competition will always be there where people and animals must strive for the scarce resources (Darwin 29). During the competition, the strong ones will win and take the power. Cooperation is a key factor during competition. Only those who tend to cooperate with their members have high chances of winning. Also, the interrelationship between cooperation and competition can give rise to power where those who…

    In the first chapter of The Greatest Show On Earth, Dawkins discusses the acceptance of evolution as fact. He says that even with the insurmountable evidence to prove that it is a fact, evolution is still considered to some degree to be just a theory. In a survey of Americans, 40% of people oppose the idea of evolution. They instead believe that humans were created independently from all other living organisms. The percentage is only slightly lower in Britain. He argues that many of those who do not believe evolution to be a fact are uninformed. He states that his purpose for writing this book is to educate these people so that they may realize the truth and change their minds.…

    Within nature Darwin has proposed the notion of natural selection as the driving force of evolution. Individuals acquiring traits solely designed for their survival and reproductive fitness. Accordingly, animals act selfishly to survive and pass along their genes to future generations. Since then, controversy has circled around the idea of organisms acting out in a selfless manor decreasing their fitness for the success of another member’s fitness. Its puzzling to assume individuals will sacrifice themselves for the benefit of another member when Darwin’s assumptions were predominately associated with the survival of the fittest. Explanations to this issue have been observed amongst kin where family members will help the survival of its relatives in order to increase the success of the group; this is otherwise known as kin selection and is one explanation of altruism. Similarly,…
