However, from a comparison with Dawkins’ discussion of this very same point, it would seem both Gould’s and Dover’s comments are more a critique of his sloppy usage than a difference of views.

El Gen Egoista / the Selfish Gene

I am not advocating a morality based upon evolution “. Another example is the existence of segregation distorter genes that are detrimental to their host, but nonetheless propagate themselves at its expense.

Moreover, genetic rearrangement occurs Dawkins examines childbearing and raising children as evolutionary strategies. 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.

Principles Of Comparative Psychology Digital printing of ed. The Social Meaning of Modern Biology.

Letters on the Eichard of Life and Human Nature. In fact, Dawkins has proposed that it is at the level of the extended phenotype: Although Dawkins agrees that groups can assist survival, they rank as a “vehicle” for survival only if the group activity is replicated in descendants, recorded in the gene, the gene being the only true replicator. These unselected for but transmitted DNA variations connect the individual genetically to its parents, but confer no survival benefit. Wikiquote has quotations related to: A Darwinian View Paperback reprint of ed.


In that case, the strategy of having a female offspring is safe, as she’ll have a pup, but the strategy of having a male can bring a large return dozens of pupseven though many males live out their lives as bachelors. Although Dawkins and biologists in general recognize these phenomena result in more copies of a gene, evidence is inconclusive whether this dswkins is selected for at a group or individual level.

Retrieved 6 January His contention is that the genes that are 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. Retrieved 18 November My Life in Science Science in the Soul: According to Godfrey-Smith, this more careful vocabulary has cleared up “misunderstandings in the “units of selection” debates.

We will call it the Replicator.

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 dwakins gene for altruism towards non-kin. An example of this might be a gene that protects the organism against a disease.

Almost all research in inclusive-fitness theory has been the opposite: Modern versions of “multilevel selection” claim to have overcome the original objections, [16] namely, that at that time no known form of group selection led to an evolutionarily stable strategy. Ayer ‘s Language, Truth, and Logic Although supported by Dawkins and by many others, this claim continues to be disputed.

The Selfish Gene – Wikipedia

Survival of the Fittest. 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.


The Selfish Gene 30th Anniversary ed. As an example, see Thompson.

Amotz Zahavi ‘s theory of honest signalling explains stotting as a selfish act, he argues, improving the springbok’s chances of escaping from a predator by indicating how difficult the chase would be. 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.

The Evolution of Human Sexuality Paperback ed. Compatibility between Cultural and Biological Approaches. The conflict arises in part over defining concepts:.

The final chapter of the first edition introduced the idea of the memea culturally-transmitted entity such as a hummable tune, by analogy to genetic transmission.

The book has been translated into at least 23 languages including Arabic, Thai and Turkish. From the gene-centred view, it follows that 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.
