"What is it that makes natural selection succeed as a solution to the problem of improbability, whereas chance and design both fail at the starting gate? The answer is that natural selection is a cumulative process, which breaks the problem of improbability up into small pieces. Each of the small pieces is slightly improbable, but not prohibitively so. (p. 153)
