Darwin was his own severest critic. He raised many of the concerns voiced by the Intelligent Design movement long before they did. His chapter VI was entitled, Difficulties of the Theory. He states:
Long before the reader has arrived at this part of my work, a crowd of difficulties will have occurred to him. Some of them are so serious that to this day I can hardly reflect on them; but, to the best of my judgment, the greater number are only apparent, and those that are real are not, I think, fatal to the theory.
Each of the issues that bothered Darwin has been incorporated into the objections of the Intelligent Design group as evidence for the failure of Darwin’s Theory of Evolution. Darwin thought of them first and, of course, did not view them as evidence against his theory. As outlined above he had an explanation for many of the anomalies. The solution of others would require waiting for further advances in biological knowledge.
Darwin was his own most severe critic. He recognized that his theory was a work in progress and that some issues were troublesome, even to him. These included:
These issues largely had to await the work of others to be fully resolved.
