The Selfish Gene is a book on evolution by Richard Dawkinseboista which the author builds upon the principal theory of George C. Laying down a path in walking: The conflict arises in part over defining concepts:.

Another example is the existence of segregation distorter genes that are detrimental to their host, but nonetheless propagate themselves at its expense.

The claim is made that these “selfish” actions of genes lead to unselfish actions by organisms. Thompson objects that the gene cannot operate by itself, egkista it requires an environment such as a cell, and life is “the creative outcome of highly structured contingencies”.
Moreover, genetic rearrangement occurs Retrieved 18 November 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.
The original replicator Dawkins’ R eplicator was the initial molecule which first managed to reproduce itself and dawkisn gained an advantage over other molecules within the primordial soup. This page was last edited on 8 Decemberat It was accompanied by a festschrift entitled Richard Dawkins: Dawkins says that his “purpose” in writing The Selfish Gene is “to examine the biology of selfishness and altruism. The second edition added two more chapters.
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. 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.

Dawkins did not deviate from this tradition. Donald Symons also finds it inappropriate to use anthropomorphism in conveying scientific meaning in general, and particularly for the present instance.

Dawkins begins by discussing the altruism that people display, indicating that he will argue it is explained by gene selfishness, and attacking group selection as an explanation.
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.
Fisher showed that the optimal sex ratio is These examples might suggest that there is a power struggle between genes and their interactor. Wynne-Edwardsarguing instead that each parent necessarily behaves selfishly. An extended discussion of the contrasts between enactivism and Dawkins’ views, and with their support by Dennettis provided by Thompson.
He then introduces the idea of the evolutionarily stable strategyand uses it to explain why alternative competitive strategies like bullying and retaliating exist.
Dawkins’ major concluding theme, that humanity is finally gaining power over the “selfish replicators” by virtue of their intelligence, is criticized also by primatologist Frans de Waalwho refers to it as an example of a ” veneer theory ” the idea that morality is not fundamental, but is laid over a brutal foundation.
In fact, the claim is that there isn’t much of a struggle because the genes usually win without a fight.
