In books such as The Blind Watchmaker, a crucial part of the argument concerns whether there exists a continuous path, leading from the origins of life to man, each step of which is both favoured by natural selection, and small enough to have happened by chance. It appears to be presented as a matter of logical necessity that such a path exists, but actually there is no such logical necessity; rather, commonly made assumptions in evolution theory require the existence of such a path. Once one admits this, one must admit also that large parts of the argument are, as often is the case in science, hypothetical in character, but it seems it would be too dangerous to bring this fact to readers' attention.
