The Selfish Gene is a book on evolution by Richard Dawkins, published in 1976. It builds upon George C. Williams's first book Adaptation and Natural Selection, which argued that selection occurred at the level of the gene mediated by the phenotype and did not occur at the group level. Dawkins used the term "selfish gene" as a way of popularizing this gene-centered view of evolution further developed during the 1960s by W. D. Hamilton and others that opposed group selection and selection aimed directly at benefit to the individual organism:
- "Despite the principle of 'survival of the fittest' the ultimate criterion which determines whether [a gene] G will spread is not whether the behavior is to the benefit of the behaver, but whether it is to the benefit of the gene G...With altruism this will happen only if the affected individual is a relative of the altruist, therefore having an increased chance of carrying the gene.
- — W.D. Hamilton, The evolution of altruistic behavior pp. 354-355
From the genocentric view, the more two individuals are genetically related, the more sense (at the level of the genes) it makes for them to behave selflessly with each other. An organism is expected to evolve to maximize its inclusive fitness—an individual's own reproductive success plus the success of its relatives (weighted by their relatedness).
In Dawkins' words, natural selection favors genes that build survival machines (later called vehicles to include both individuals and some select groups), and more flamboyantly, "gigantic lumbering robots". In other words, according to genocentrism, organisms evolve as elaborate contraptions constructed and controlled by genes, and evolution selects among these competing phenotypes or "interactors", not by altering the activity or form of the underlying genes ("replicators"), but simply by proliferating those mutated instructions that engender construction of the most successful survival machines. The result of this phenotypic evolution, it is claimed, is to select gene populations with an evolutionarily stable strategy.
- "Selection has favoured genes that cooperate with others. In the fierce competition for scarce resources...there must have been a premium on central coordination rather than anarchy within the communal body."
- — Richard Dawkins, The Selfish Gene, p. 47
- "The best strategy for an individual depends upon what the majority of the population are doing. Since the rest of the population consists of individuals, each one trying to maximize his own success, the only strategy that persists will be one which, once evolved, cannot be bettered by any deviant individual."
- — Richard Dawkins, The Selfish Gene, p. 69
This evolutionarily stable, cooperative strategy that suppresses deviancy is the extent of the selfish gene's support of altruism. For greater support, humans have to depend upon their intelligence to augment what the selfish gene can provide.
The book also coins the term meme for a unit of human cultural evolution analogous to the gene, suggesting that "selfish" replication of the meme might model the spreading of human culture. Dawkins elaborated later upon his concept of 'meme' as follows:
- "A meme should be regarded as a unit of information residing in a brain...It has a definite structure, realized in whatever physical medium the brain uses for storing information...The phenotypic effects...are the the outward and visible (audible, etc.) manifestations of the memes within the brain. They [the phenotypic effects] may be perceived by the sense organs of other individuals and may so imprint themselves on the brains of the receiving individuals that a copy (not necessarily exact) of the original meme is graven in the receiving brain."
- — Richard Dawkins, The Extended Phenotype: The Long Reach of the Gene, p. 109
Memetics has become a field of study, although it has not become well established in scientific circles. Proponents describe memetics as an approach to evolutionary models of cultural information transfer..
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.

In describing genes as being "selfish", the author does not intend (as he states unequivocally) to imply that they are driven by any motives or will, but merely that their effects can be metaphorically and pedagogically described as if they were. The contention is that the genes that get passed on are the ones whose evolutionary consequences serve their own implicit interest (to continue the anthropomorphism) in being replicated, not necessarily those of the organism. In later work, Dawkins brings evolutionary "selfishness" down to creation of a successful extended phenotype.
For some, the metaphor of "selfishness" is entirely clear, while to others it is confusing, misleading, or simply silly to ascribe mental attributes to something that is mindless. For example, Andrew Brown has written:
- "“Selfish”, when applied to genes, doesn't mean “selfish” at all. It means, instead, an extremely important quality for which there is no good word in the English language: “the quality of being copied by a Darwinian selection process.” This is a complicated mouthful. There ought to be a better, shorter word—but “selfish” isn't it."
- "In summary, the rhetoric of The Selfish Gene exactly reverses the real situation: through [the use of] metaphor genes are endowed with properties only sentient beings can possess, such as selfishness, while sentient beings are stripped of these properties and called machines...The anthropomorphism of genes...obscures the deepest mystery in the life sciences: the origin and nature of mind."
Genes and selection
Dawkins proposes the idea of the "replicator":
- "It is finally time to return to the problem with which we started, to the tension between individual organism and gene as rival candidates for the central role in natural selection...One way of sorting this whole matter out is to use the terms ‘replicator’ and ‘vehicle’. The fundamental units of natural selection, the basic things that survive or fail to survive, that form lineages of identical copies with occasional random mutations, are called replicators. DNA molecules are replicators. They generally, for reasons that we shall come to, gang together into large communal survival machines or ‘vehicles’."
- — Richard Dawkins, The Selfish Gene, p. 253 (Anniversary Edition)
The original replicator (Dawkins' Replicator) was the initial molecule which first managed to reproduce itself and thus gained an advantage over other molecules within the primordial soup. As replicating molecules became more complex, Dawkins postulates, the replicators became the genes within organisms, with each organism's body serving the purpose of a 'survival machine' for its genes.
Dawkins writes that gene combinations which help an organism to survive and reproduce tend to also improve the gene's own chances of being passed on and, as a result, frequently "successful" genes will also be beneficial to the organism. An example of this might be a gene that protects the organism against a disease, which helps the gene spread and also helps the organism.
Genes can reproduce at the expense of the organism
There are other times when the implicit interests of the vehicle and replicator are in conflict, such as the genes behind certain male spiders' instinctive mating behaviour, which increase the organism's inclusive fitness by allowing it to reproduce, but shorten its life by exposing it to the risk of being eaten by the cannibalistic female. Another good example is the existence of segregation distortion genes that are detrimental to their host but nonetheless propagate themselves at its expense. Likewise, the existence of junk DNA that provides no benefit to its host, once a puzzle, can be more easily explained.
Power struggles are rare
These examples might suggest that there is a power-struggle between genes and their host. In fact, the claim is that there isn't much of a struggle because the genes usually win without a fight. However, in particular, if the organism becomes intelligent enough to understand its own interests, as distinct from those of its genes, there can be true conflict.
An example of such a conflict might be a person using birth control to prevent fertilization, thereby inhibiting the replication of his or her genes. But this action might not be a conflict of the 'self-interest' of the organism with his or her genes, since a person using birth control might also be enhancing the survival chances of their genes by limiting family size to conform with available resources, thus avoiding extinction as predicted under the Malthusian model of population growth.
Dawkins says that in writing The Selfish Gene "My purpose is to examine the biology of selfishness and altruism." p. 1 He does this by supporting the claim that "gene selfishness will usually give rise to selfishness in individual behaviour. However, as we shall see, there are special circumstances in which a gene can achieve its own selfish goals best by fostering a limited form of altruism at the level of individual animals." p. 2 Gene selection provides one explanation for kin selection and eusociality, where organisms act altruistically, against their individual interests (in the sense of health, safety or personal reproduction), namely the argument that by helping related organisms reproduce, a gene succeeds in "helping" copies of themselves (or sequences with the same phenotypic effect) in other bodies to replicate. The claim is made that these "selfish" actions of genes lead to unselfish actions by organisms. An interesting aspect of this claim, exampled at the animal level by Dawkins in Chapter 10: You scratch my back, I'll ride on yours, is to explain how genes achieve kin recognition, or orchestrate mutualism and coevolution. Although Dawkins (and biologists) recognize these phenomena result in more copies of a gene, evidence is inconclusive whether this success is selected for at a group or individual level. In fact, Dawkins has proposed that it is at the level of the extended phenotype:
- "We agree [referring to Wilson and Sober's book Unto others: The evolution and psychology of unselfish behavior] that genes are replicators, organisms and groups are not. We agree that the group selection controversy ought to be a controversy about groups as vehicles, and we could easily agree to differ on the answer...I coined the [term] vehicle not to praise it but to bury it....Darwinism can work on replicators whose phenotypic effects (interactors) are too diffuse, too multi-levelled, too incoherent to deserve the accolade of vehicle...Extended phenotypes can include inanimate artifacts like beaver dams...But the vehicle is not something fundamental...Ask rather “Is there a vehicle in this situation and, if so, why?”"
- —Richard Dawkins, Burying the Vehicle
Although Dawkins agrees that groups can assist survival, they rank as a 'vehicle' for survival only if the group activity is replicated in decedents, recorded in the gene, the gene being only true replicator. An improvement in the survival lottery for the group must improve that for the gene for sufficient replication to occur. Dawkins argues qualitatively that the lottery for the gene is based upon a very long and broad record of events, and group advantages are usually too specific, too brief, and too fortuitous to change the gene lottery.
- -"We can now see that the organism and the group of organisms are true rivals for the vehicle role in the story, but neither of them is even a candidate for the replicator role. The controversy between ‘individual selection’ and ‘group selection’ is a real controversy between alternative vehicles...As it happens the outcome, in my view, is a decisive victory for the individual organism. The group is too wishy-washy an entity."
- —Richard Dawkins, The Selfish Gene, pp. 254-255
Prior to the 1960s, it was common for altruism to be explained in terms of group selection, where the benefits to the organism or even population were supposed to account for the popularity of the genes responsible for the tendency towards that behaviour. 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. The claim still is made by some that it would take only a single individual with a tendency towards more selfish behaviour to undermine a population otherwise filled only with the gene for altruism towards non-kin.
The book was extremely popular when first published, caused "a silent and almost immediate revolution in biology", and continues to be widely read. It has sold over a million copies, and has been translated into more than 25 languages. An extended discussion of Dawkins' views and his book The Selfish Gene is provided by Wilkins and Hull.
Proponents argue that the central point, that replicating the gene is the object of selection, usefully completes and extends the explanation of evolution given by Charles Darwin before the basic mechanisms of genetics were understood.
Critics argue that it oversimplifies the relationship between genes and the organism. According to Alan Grafen, acceptance of adaptionist theories is hampered by a lack of a mathematical unifying theory and a belief that anything in words alone must be suspect. According to Grafen, these difficulties along with an initial conflict with population genetics models at the time of its introduction "explains why within biology the considerable scientific contributions it [The Selfish Gene] makes are seriously underestimated, and why it is viewed mainly as a work of exposition." According to comparative psychologist Nicky Hayes, "Dawkins presented a version of sociobiology that rested heavily on metaphors drawn from animal behavior, and extrapolated these...One of the weaknesses of the sociological approach is that it tends only to seek confirmatory examples from among the huge diversity of animal behavior. Dawkins did not deviate from this tradition."
In 1976, Arthur Cain, one of Dawkins's tutors at Oxford in the 1960s, called it a "young man's book" (which Dawkins points out was a deliberate quote of a commentator on A.J. Ayer's Language, Truth, and Logic); Dawkins later noted he had been "flattered by the comparison, [but] knew that Ayer had recanted much of his first book and [he] could hardly miss Cain's pointed implication that [he] should, in the fullness of time, do the same." This point also was made by Mary Midgley: "The same thing happened to AJ Ayer, she says, but he spent the rest of his career taking back what he'd written in Language, Truth and Logic. “This hasn't occurred to Dawkins”, she says. “He goes on saying the same thing.”" However, according to Wilkins and Hull, Dawkins' thinking has developed, although perhaps not defusing this criticism:
- "In Dawkins' early writings, replicators and vehicles played different but complementary and equally important roles in selection, but as Dawkins honed his view of the evolutionary process, vehicles became less and less fundamental... In later writings Dawkins goes even further and argues that phenotypic traits are what really matter in selection and that they can be treated independently of their being organized into vehicles....Thus, it comes as no surprise when Dawkins proclaims that he “coined the term ‘vehicle’ not to praise it but to bury it.” As prevalent as organisms might be, as determinate as the causal roles that they play in selection are, reference to them can and must be omitted from any perspicuous characterization of selection in the evolutionary process. Dawkins is far from a genetic determinist, but he is certainly a genetic reductionist."
- — John S Wilkins, David Hull, Dawkins on Replicators and Vehicles, The Stanford Encyclopedia of Philosophy
Units of selection
"One internally consistent logical picture is that the unit of replication is the gene,...and the organism is one kind of ...entity on which selection acts directly." Dawkins proposed the matter without a distinction between 'unit of replication' and 'unit of selection' that he made elsewhere: "the fundamental unit of selection, and therefore of self-interest, is not the species, nor the group, nor even strictly the individual. It is the gene, the unit of heredity." However, he continues in a later chapter:
- "On any sensible view of the matter Darwinian selection does not work on genes directly. ...The important differences between genes emerge only in their effects. The technical word phenotype is used for the bodily manifestation of a gene, the effect that a gene has on the body...Natural selection favours some genes rather than others not because of the nature of the genes themselves, but because of their consequences—their phenotypic effects...But we shall now see that the phenotypic effects of a gene need to be thought of as all the effects that it has on the world. ...The phenotypic effects of a gene are the tools by which it levers itself into the next generation. All I am going to add is that the tools may reach outside the individual body wall...Examples that spring to mind are artefacts like beaver dams, bird nests, and caddis houses."
- — Richard Dawkins, The Selfish Gene, Chapter 13, pp. 234, 235, 238
- "Dawkins claims to prefer genes and to find greater insight in this formulation. But he allows that you or I might prefer organisms—and it really doesn't matter."
- — Stephen Jay Gould, The Structure of Evolutionary Theory, pp. 640-641
The view that selection based upon organisms and populations seldom opposes selection on genes is controversial. While naïve versions of group selectionism have been disproved, more sophisticated formulations make accurate predictions in some cases while positing selection at higher levels. Nevertheless, the explanatory gains of using sophisticated formulations of group selectionism as opposed to Dawkins's gene-centred selectionism are still under dispute. Both sides agree that very favourable genes are likely to prosper and replicate if they arise and both sides agree that living in groups can be an advantage to the group members. The conflict arises in part over defining concepts:
- "Cultural evolutionary theory, however, has suffered from an overemphasis on the experiences and behaviors of individuals at the expense of acknowledging complex group organization...Many important behaviors related to the success and function of human societies are only properly defined at the level of groups".
In "The Social Conquest of Earth," E. O. Wilson contends that although the selfish-gene approach was accepted "until 2010 [when] Martin Nowak, Corina Tarnita, and I demonstrated that inclusive fitness theory, often called kin selection theory, is both mathematically and biologically incorrect." Chapter 18 of "The Social Conquest of Earth" describes the deficiencies of kin selection and outlines group selection, which Wilson argues is a more realistic model of social evolution. He criticizes earlier approaches to social evolution, saying: "...unwarranted faith in the central role of kinship in social evolution has led to the reversal of the usual order in which biological research is conducted. The proven best way in evolutionary biology, as in most of science, is to define a problem arising during empirical research, then select or devise the theory that is needed to solve it. Almost all research in inclusive-fitness theory has been the opposite: hypothesize the key roles of kinship and kin selection, then look for evidence to test that hypothesis." According to Wilson: "People must have a tribe...Experiments conducted over many years by social psychologists have revealed how swiftly and decisively people divide into groups, and then discriminate in favor of the one to which they belong." (pp. 57, 59) According to Wilson: "Different parts of the brain have evolved by group selection to create groupishness." (p. 61)
Some authors consider some facets of this debate between Dawkins and his critics about the level of selection to be blather:
- "The particularly frustrating aspects of these constantly renewed debates is that. even though they seemed to be sparked by rival theories about how evolution works, in fact they often involve only rival metaphors for the very same evolutionary logic and [the debates over these aspects] are thus empirically empty."
- — Laurent Keller, Levels of Selection in Evolution, p.4
Unit of selection or unit of evolution
Some biologists have criticised the idea that the gene is the unit of selection, but suggest the gene is the unit of evolution, on the grounds that selection is a "here and now" event of reproduction and survival, while evolution is the long-term trend of shifting allele frequencies.
Stephen Jay Gould also took issue with the gene as the unit of selection, arguing that genes are not directly 'visible' to natural selection. Rather, the unit of selection is the phenotype, not the genotype, because it is phenotypes which interact with the environment at the natural selection interface. As Kim Sterelny summarises Gould's view, "Gene differences do not cause evolutionary changes in populations, they register those changes". This is also Niles Eldredge's view. Eldredge notes that in Dawkins' book A Devil's Chaplain, which was published just before Eldredge's book, "Richard Dawkins comments on what he sees as the main difference between his position and that of the late Stephen Jay Gould. He concludes that it is his own vision that genes play a causal role in evolution", while Gould (and Eldredge) "sees genes as passive recorders of what worked better than what".
Behavior genetics entertains the view:
- "that genes are dynamic contributors to behavioral organization and are sensitive to feedback systems from the internal and external environments." "Technically behavior is not inherited; only DNA molecules are inherited. From that point on behavioral formation is a problem of constant interplay between genetic potential and environmental shaping"
- —D.D. Thiessen, Mechanism specific approaches in behavior genetics, p. 91
This view from 1970 still is espoused today, and conflicts with 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". The philosophical/biological field of enactivism stresses the interaction of the living agent with its environment and the relation of probing the environment to cognition and adaptation. Gene activation depends upon the cellular milieu. An extended discussion of the contrasts between enactivism and Dawkins' views, and with their support by Dennett, is provided by Thompson.
Another criticism of the book is its treatment of morality, and more particularly altruism, as existing only as a form of selfishness:
- "It is important to realize that the above definitions of altruism and selfishness are behavioural, not subjective. I am not concerned here with the psychology of motives...My definition is concerned only with whether the effect of an act is to lower or raise the survival prospects of the presumed altruist and the survival prospects of the presumed beneficiary."
- — Richard Dawkins, The Selfish Gene, p. 12
- ""We can even discuss ways of cultivating and nurturing pure, disinterested altruism, something that has no place in nature, something that has never existed before in the whole history of the world."
- — Richard Dawkins, The Selfish Gene, p. 179
Philosopher Mary Midgley has suggested this position is a variant of Hobbes' explanation of altruism as enlightened self-interest, and that Dawkins goes a step further to suggest that our genetic programming can be overcome by what amounts to an extreme version of free will. Part of Mary Midgley's concern is that Richard Dawkins' account of The Selfish Gene serves as a moral and ideological justification for selfishness to be adopted by modern human societies as simply following "nature", providing an excuse for behavior with bad consequences for future human society.
Dawkins' major concluding theme, that humanity is finally gaining power over the "selfish replicators" by virtue of their intelligence, is criticized by Midgley and also by primatologist Frans de Waal, who refers to it as an example of a "veneer theory" (the idea that morality is not fundamental, but is laid over a brutal foundation). Dawkins claims he merely describes how things are under evolution, and makes no moral arguments.
More generally, the objection can be put that The Selfish Gene discusses philosophical and moral questions that go beyond biological arguments, relying upon anthropomorphisms and careless analogies.
The Selfish Gene was first published in 1976 in eleven chapters with a preface by the author and a foreword by Robert Trivers. A second edition was published in 1989. This edition added two extra chapters, and substantial endnotes to the preceding chapters, reflecting new findings and thoughts. It also added a second preface by the author, but the original foreword by Trivers was dropped.
In 2006, a 30th anniversary edition was published which reinstated the Trivers foreword and contained a new introduction by the author (alongside the previous two prefaces), with some selected extracts from reviews at the back. It was accompanied by a festschrift entitled Richard Dawkins: How a Scientist Changed the Way We Think. In March 2006, a special event entitled The Selfish Gene: Thirty Years On was held at the London School of Economics. The event was organised by Helena Cronin, and chaired by Melvyn Bragg. In March 2011, Audible Inc published an audiobook edition narrated by Richard Dawkins and Lalla Ward.
There are many versions of The Selfish Gene on line. Some have page numbers, some don't, and some are formatted and some are not. The various versions have different access to pages.
