The '''Cambrian explosion''' is the term used to describe a period of geological history approximately 540-million years ago in which every current complex [[phyla]] first appeared in the [[fossil record]]. Because of this, it has been dubbed the "Big-Bang"of life". Scientists and others have vigorously debated the meaning of this for over a hundred years. 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]]<ref>http://www.burgess-shale.bc.ca/</ref>. 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 <i>Smithsonian Miscellaneous Collections</i>. The findings were then <i>conveniently</i> ignored for several decades<ref>http://www.thedesignoflife.net/blog/Critical-decisions-in-science-The-Smithsonian-secretary-vs-the-Cambrian-explosion/View/Default.aspx</ref>.

In the documentary "[[The Case for a Creator|The Case for a Creator]]", [[Intelligent Design]] proponent and respected biologist [[Jonathan Wells]] had this to say about the Cambrian explosion:
{{cquote| 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.<ref>http://www.uncommondescent.com/intelligent-design/qa-part-3-jonathan-wells-on-the-cambrian-explosion-and-darwinism-as-a-science-stopper/</ref>}}
