Richard Dawkins – “Irreducible Complexity” (2006)
The greater the statistical improbability, the less plausible is chance as the solution: that is what improbable means. But the candidate solutions to the riddle of improbability are not, as is falsely implied, design and chance. They are design and natural selection. Chance is not a solution, given the high levels of improbability we see in living organisms, and no sane biologist ever suggested that it was.
