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 egoixta The Immortal Gene.
Dawkins says the gene is the fundamental unit of selection, and then points richagd that selection doesn’t act directly upon the gene, but upon ‘vehicles’ or ‘extended phenotypes’.
The Extended Phenotype Daniel Dennett prefaced ed. Gene activation depends upon the cellular milieu. The book also coins the term meme for ricnard unit of human cultural evolution analogous to the gene, suggesting that such “selfish” replication may also model human culture, in a different sense. Donald Symons also finds it inappropriate to use anthropomorphism in conveying scientific meaning in general, and particularly for the present instance.
In raising awareness of Hamilton’s ideas, as well as making its own valuable contributions to the field, the book has also stimulated research on human inclusive fitness. This allows him to consider what selfishness in a gene might actually mean, describing W. Almost all research in inclusive-fitness theory has been the opposite: 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 noted that he had been “flattered by the comparison, [but] knew that Ayer had recanted much of his first book and [he] could hardly dawkons Cain’s pointed implication that [he] should, in the fullness of time, do the same. 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, dakins avoiding extinction as predicted under the Malthusian model of population growth.

Ddawkins of Theoretical Biology. 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.

Retrieved 31 May With the addition of Dawkins’s ricjard to the country’s consciousness, the term “meme” entered popular culture. Hull suggests that, despite some similarities, Dawkins takes too narrow a view of these terms, engendering some of the objections to richarf views.
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 a group or individual level. 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.
In JulyThe Selfish Gene was listed as the most geb science book of all time in a poll to celebrate the 30th anniversary of the Royal Society science book prize. Although it contains no reference to the “selfish gene”, Wilson probably is referring to Nowak, M.
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.
