I received the book, Darwin’s Doubt, by Stephen C. Meyer, as a gift and have been reading and reviewing it on this blog. I learn better by processing what I read, and processing, for me, means writing.
In the first installment, I breezed through the first four chapters of the book in which Meyer introduces the problem of “Darwin’s doubt”, the Cambrian Explosion. Darwin knew the sudden proliferation of life forms in the Cambrian era was a problem to his theory, but hoped future discoveries would prove his theory right.
The Theory of Evolution necessarily requires long periods of gradual change in which natural selection works to weed out unproductive traits in favor of productive traits, slowly and almost imperceptibly evolving from simple life forms to more complex life forms and from one life form to another life form.
The Cambrian “explosion” contraindicated Darwin’s Theory of Evolution. Darwin, himself, highlighted that fact, but he assumed that future discoveries would fill in the missing gaps that did not appear in the fossil record in his time. Meyer traces the most relevant history since Darwin’s time to “tell the rest of the story”, which turns out does not confirm his assumption. In fact, subsequent discoveries accentuate the problem.
In the next two chapters, Meyer explains how the scientific community has attempted to fill that gap with solutions that explain away the gap. Rather than question Darwin’s theory, they have moved to the molecular record to vindicate the theory to which the scientific community long ago committed. Meyer carefully explains how the Cambrian gap and less remarkable (but no less significant) Precambrian gap are not bridged by molecular analysis or anatomical analysis.
