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. 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 Social Meaning of Modern Biology.

samllubny 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 the genes responsible for the tendency towards that behaviour.


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.

He criticises earlier approaches to social evolution, saying: Stephen Jay Gould finds Dawkins’ position tries to have it both ways: In the foreword to the book’s 30th-anniversary edition, Dawkins said he “can readily see that [the book’s title] might give an samklubny impression of its contents” and in retrospect thinks he should have taken Tom Maschler ‘s advice and called the book The Immortal Gene.

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. A Darwinian View Paperback ed. Thompson goes on to suggest that the cell-environment interrelationship has much to do with reproduction and inheritance, and a focus on the gene as a form of “information [that] passes through bodies and affects them, but is not affected by them on its way through” [51] is tantamount to adoption of a form of material-informational dualism that has no explanatory value and no scientific basis.

In fact, the claim is that there isn’t much of a struggle because the genes usually win without a fight.

From Wikipedia, the free encyclopedia. Williams ‘s Adaptation and Natural Selection Dawkins’ later formulation is in his book The Extended Phenotypewhere the process of selection is taken to involve every possible phenotypical effect of a gene. Although it contains no reference to the “selfish gene”, Wilson probably is referring to Nowak, M.

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. Dawkins says the gene is the fundamental unit of selection, and then points out that selection doesn’t act directly upon the gene, but upon ‘vehicles’ or ‘extended phenotypes’. 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.
