I am deep into the book, Darwin’s Doubt, by Stephen C. Meyer, and chronicling my way through it. The title of the book comes from the problem that the Cambrian explosion posed, and still poses, to evolutionary theory. In the first article, the problem that first appears in the fossil record is explained. In the next article, some possible solutions to the problems are explored and discarded. In the third article, we begin to look to genes for possible solutions, and that sets the stage for this article.
The origin of the animals that appeared suddenly in the Cambrian period necessarily required vast amounts of new functional information. Where did it come from and how did it arise? The discovery of DNA as information retaining and building mechanisms seemed to present great hope for a solution, but that is not the story the history of exploring this solution tells. In fact, the study of DNA has only accentuated the problem.
