Darwin's theory of evolution by natural selection is the only workable explanation that has ever been proposed for the remarkable fact of our own existence, indeed the existence of all life wherever it may turn up in the universe.
p. xv (The Theory of Evolution (1958))
This argument [that life is too improbable to have arisen by chance] comes up repeatedly: its latest manifestation is Hoyle's discussion of the likelihood of a wind blowing through a junkyard assembling a Boeing 707 [sic]. What is wrong with it? Essentially, it is that no biologist imagines that complex structures arise in a single step.John Maynard Smith
It is in the nature of science that once a position becomes orthodox it should be suggested to criticism.... It does not follow that, because a position is orthodox, it is wrong.John Maynard Smith
It is an occupational risk of biologists to claim, towards the end of their careers, that the problems which they have not solved are insoluble.John Maynard Smith
Paradoxically, it has turned out that game theory is more readily applied to biology than to the field of economic behavior for which it was originally designedJohn Maynard Smith
Evolutionary game theory is a way of thinking about evolution at the phenotypic level when the fitnesses of particular phenotypes depend on their frequencies in the population.John Maynard Smith
