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.
These unselected for but transmitted DNA variations connect the individual genetically to its parents, but confer no survival benefit. The claim is made that these "selfish" actions of genes lead to unselfish actions by organisms. Fisher showed that the optimal sex ratio is Background[ edit ] Dawkins builds upon George C.
Again, the offspring share genes with nest mates, so brothers and sisters satisfied with "just enough for all" will survive in greater numbers than totally selfish siblings. This is the book in which Dawkins introduces the theory of memes — the seemingly self-replicating pool of art and science, literature and music, knowledge, folklore and platitude that survives with each human life — and indeed coins the word itself, and fires the opening salvoes in what will become his all-out intellectual artillery assault on aspects of religion.
The phenotypic effects of a gene are the tools by which it levers itself into the next generation.
In fact, Dawkins has proposed that it is at the level of the extended phenotype: Many important behaviors related to the success and function of human societies are only properly defined at the level of groups".
He attacks the idea of group selection for the good of the species as proposed by V. 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 The important differences between genes emerge only in their effects.
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.

A real war of the sexes picture is painted by the author as he suggests that it might be better for the gene machine to breed and then selfishly leave the other partner to raise the young while it goes off to breed again.
Darwinism can work on replicators whose phenotypic effects interactors are too diffuse, too multi-levelled, too incoherent to deserve the accolade of vehicle It is the desire of the author that as thinking beings we can think more deeply about ideas in an altruistic manner.
Wynne-Edwardsarguing instead that each parent necessarily behaves selfishly. Plot overview and analysis written by an experienced literary critic. 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.
Why are sperm small and eggs large? Hamilton, The Evolution of Altruistic Behavior, pp. This is the famous "just-so" story of evolution: Similarly, Dawkins argues, there are conflicts of interest between males and females, but he notes that R. Using advanced math and computer simulated games, the author shows why the most selfish survival tactic of any individual is not to directly attack others in its group even though they compete with him for food and mates.
