Experiments conducted over many years by social psychologists have revealed how swiftly and decisively people divide into groups, geoista then discriminate in favor of the one to which they belong. Dawkins writes that gene combinations which help an organism to survive and reproduce tend to also improve the gene’s own chances of being replicated, and, as a result, “successful” genes frequently provide a benefit to the organism.
A Darwinian View Paperback ed. Levels of Selection in Evolution. Dawkns uses the term “selfish gene” as a way of expressing the gene-centred view of evolution as opposed to the views focused on the organism and the grouppopularising ideas developed during the s by W. This view from is still espoused today,   and conflicts etoista Dawkins’ view of “the gene as a form of “information [that] passes through bodies and affects them, but is not affected by them on its way through””.
Stephen Jay Gould finds Dawkins’ position tries to have it both ways: Dawkins begins by discussing the altruism that people display, indicating that he will argue it is explained by gene selfishness, and attacking dawknis selection as an explanation. As an example, see Thompson. I am not advocating a morality based upon evolution “.

Hull suggests that, despite some similarities, Dawkins takes too narrow a view of these terms, engendering some of the objections to his views.

The Selfish Gene 30th Anniversary ed. Retrieved from ” https: He considers the origin of life with the arrival of molecules able to replicate themselves. Wilson contends that although the selfish-gene approach was accepted “until [when] Martin Nowak, Corina Tarnita, and I demonstrated that inclusive fitness theory, often called kin selection theory, is both mathematically and biologically incorrect. Modern versions of “multilevel selection” claim to have overcome the original objections,  namely, that at that time no known form of group selection led to an evolutionarily stable strategy.
An extended discussion of the contrasts between enactivism and Dawkins’ views, and with their support by Dennettis provided by Thompson. These unselected for but transmitted DNA variations connect the individual genetically to its parents, but confer no survival benefit.
An example of this might be a gene that protects the organism against a disease. Other authors say Dawkins has failed to make some critical distinctions, in particular, the difference between group selection for group advantage and group selection conveying individual advantage. Williams ‘s book Adaptation and Natural Selectionwhich argued that altruism is not based upon group benefit per se but is a result of selection that occurs “at the level of the gene mediated by the phenotype ”  and any selection at the group level occurred only under rare circumstances.
Prior to the s, it was common for altruism to be explained in terms of group selectionwhere the benefits to the organism or even population were supposed to account for the popularity of rgoista genes responsible for the tendency towards that behaviour. As a result, populations will tend towards an evolutionarily stable strategy.
More generally, the objection has been made that The Selfish Gene discusses philosophical and moral questions that go beyond biological arguments, relying upon anthropomorphisms and dawkine analogies.
The Modern Denial of Human Nature. In the foreword to the book’s 30th-anniversary edition, Dawkins said he “can readily see that [the book’s title] might give an inadequate impression of its contents” and in retrospect thinks he should have taken Tom Maschler ‘s advice and called the book The Immortal Gene.
My Life in Science Science in the Soul: The Social Meaning of Modern Biology. Although Dawkins and biologists in general recognize these phenomena result in more copies of a gene, evidence is inconclusive whether this success is selected for at ben group or individual level. In JulyThe Selfish Gene was listed as the most influential science book of all time in a poll to celebrate the 30th anniversary of the Egkista Society science book prize.
Updated Preface by the author.
According to the ethologist Alan Grafenacceptance of adaptionist theories is hampered by a lack of a mathematical unifying theory and a belief that anything dgoista words alone must be suspect. Thompson objects that the gene cannot operate by itself, since it requires an environment such as a cell, and life is “the creative outcome of highly structured contingencies”.
Dawkins builds upon George C.
He attacks the idea of group selection for the good of the species as proposed by V. In Marcha special event entitled The Selfish Gene: To describe the gene as egoisya program sending instructions to cells belittles the complexity of eyoista gene It is the gene, the unit of heredity. The Cambridge Companion to the Philosophy of Biology. Ina 30th-anniversary edition  was published with the Trivers foreword and a new introduction by the author.
El gen egoista / The Selfish Gene : Richard Dawkins :
Altruism too can evolve, as in the social insects such as ants and bees, where workers give up the right to reproduce in favour of a sister, the queen; in their case, the unusual haplodiploid system of sex determination may have helped to bring this about, as females in a nest are exceptionally closely related.
Williams ‘s Adaptation and Natural Selection A question is whether parents should invest in their offspring equally or should favour some of them, and explains that what is best for the survival of the parents’ genes is not always best for individual children. The word ’cause’ here is somewhat tricky: The book also coins the term meme for a unit of human cultural evolution analogous to the gene, suggesting that such “selfish” replication may also model human culture, in a different sense.
Hamilton and others who opposed group selection and selection aimed directly at benefit to the individual organism:
