The ninth chapter (The Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life. Ed. J.W. Burrow. London: Penguin Books, 1979, 291-317) made it clear, from what Darwin modestly calls the "great imperfection of the geological record" that the theory was not in principle falsifiable, though the possibility that some kind of evidence or another should be able in principle to disprove a theory is a condition (if we can believe logicians like Karl Popper) for it to be considered scientific. By its nature, fossil evidence of intermediate forms that could prove or disprove the theory remained unfound and unfindable. When I read this, it was not clear to me how such an theory could be called "scientific".
If evolution is not scientific, then what is it? It seems to me that it is a human interpretation, an endeavor, an industry, a literature, based on what the American philosopher Charles Peirce called abductive reasoning, which functions in the following way:
(1) Suprising fact A.
(2) If theory B were the case, then A would naturally follow.
(3) Therefore B.
Here, (1) alone is certain, (2) is merely probable (as it explains the facts, though does not preclude other possible theories), while (3) has only the same probability as (2). If you want to see how ironclad the case for the evolution of man is, make a list of all the fossils discovered so far that "prove" the evolution of man from lower life forms, date them, and then ask yourself if abductive reasoning is not what urges it, and if it really precludes the possibility of quite a different (2) in place of the theory of evolution.
