The Selfish Gene Another criticism of the book is its treatment of morality, and more particularly altruism, as existing only as a form of selfishness: The philosopher Mary Midgley has suggested this position is a variant of Hobbes' explanation of altruism as enlightened self-interest, and that Dawkins goes a step further to suggest that our genetic programming can be overcome by what amounts to an extreme version of free will. Part of Mary Midgley's concern is that Richard Dawkins' account of "The Selfish Gene" serves as a moral and ideological justification for selfishness to be adopted by modern human societies as simply following
Alternatives to evolution by natural selection through a population when they were beneficial, helped by natural selection. This represented the germ of the modern synthesis, and the beginning of the end for mutationism as an evolutionary force. Contemporary biologists accept that mutation and selection both play roles in evolution; the mainstream view is that while mutation supplies material for selection in the form of variation, all non-random outcomes are caused by natural selection. Masatoshi Nei argues instead that the production of more efficient genotypes by mutation is fundamental for evolution, and that evolution is often mutation-limited. The endosymbiotic theory implies rare but major events of saltational
