The Cambrian explosion is how every current complex phylum appeared suddenly in the fossil record, contrary to what was expected by the slowly evolving lifeforms predicted by the Theory of Evolution. Lacking a coherent explanation, Darwinists and Old-Earth creationists describe this period, which they claim was 540 million years ago, as the "Big-Bang of life." In fact, the Cambrian explosion casts serious doubt on the idea that significant new forms of life came into being via slow, gradual Darwinian processes.
The Cambrian explosion was "discovered" in the Burgess Shale of British Columbia, Canada in 1909 by Charles D. Walcott, the then secretary of the Smithsonian Institute. In a moment some would say is telling of how damaging the Cambrian explosion was to Walcott's Darwinian world-view, the lone publication of his remarkable discovery was in the sparsely-read Smithsonian Miscellaneous Collections. The findings were then conveniently ignored for several decades.
|“|| How did it happen? We don’t have the foggiest idea how it happened. Assuming a jellyfish was the common ancestor — I don’t believe that — but how do you turn a jellyfish into a trilobite? How do you turn a jellyfish into a fish with a backbone? How do you do it? I don’t just mean taking a scalpel and rearranging the parts like you’re doing a collage in third-grade art class. We’re talking about a living animal here, that reproduces itself and makes more things like itself. How do you do it? We don’t have the foggiest idea.
To try to explain this away by saying Darwin’s theory accounts for it is a science-stopper. It’s the biggest science-stopper of modern history. It stops your inquiry right there. You have no more questions. Oh, all these animals just appeared. That’s not science.
