First, let’s re-cap the challenge to evolution from the phenomenon of the Cambrian explosion.
The newly released film “Darwin’s Dilemma” argues that the geologically abrupt appearance of the major groups of animals (the “phyla”) in the Cambrian Explosion posed a serious problem for Charles Darwin’s theory of evolution (as he himself knew), and that subsequent fossil discoveries—far from solving the problem—have made it worse.
Basically, all the major body plans we have today appear in the fossil record in a 2-3 million period about 543 million years ago. There are no precursors in the fossil record showing the gradual evolution of these major body plans.
Darwin expected to discover lots and lots of fossils leading up to the Cambrian explosion period that would show how all these phyla came into existence slowly over time. Unfortunately for the naturalistic evolutionists, the discoveries we’ve been making haven’t shown any hint of precursor fossils leading up the Cambrian explosion.
Since 1859, however, many Precambrian fossils have been found, including microfossils of single-celled bacteria in rocks more than three billion years old. In addition, multicellular Precambrian fossils have been found in the Ediacara Hills of Australia, though there is continuing debate over whether any—or how many—of the Ediacaran fossils were animals, or what relationship—if any—they had to the Cambrian phyla. In 1998, Cambridge University paleobiologist Simon Conway Morris (who is featured in the film “Darwin’s Dilemma”) wrote, “Apart from the few Ediacaran survivors… there seems to be a sharp demarcation between the strange world of Ediacaran life and the relatively familiar Cambrian fossils” (Crucible of Creation, 30).
But wait! Maybe we can’t find the precusor fossils required by Darwinism because they are too small or too soft to have survived for so long?

So there is now no shortage of Precambrian fossils. Not only do we have fossils of bacteria, but we also have many fossils of soft-bodied Multicellular organisms. “In the Ediacaran organisms there is no evidence for any skeletal hard parts,” wrote Conway Morris in 1998. “Ediacaran fossils look as if they were effectively soft-bodied” (Crucible of Creation, 28). The same is true of many of the organisms fossilized in the Cambrian explosion.
But wait! Scientists have discovered lots of exceptionally preserved microbes just before the Cambrian explosion. Don’t microbes count as precursors to the Cambrian explosion phyla?
Richard Callow and Martin Brasier reported in the January 2009 issue of the Journal of the Geological Society, London “a variety of exceptionally preserved microbes” from late Precambrian rocks in England that address “the paradox known as ‘“Darwin’s dilemma’.”
[…]Callow and Brasier didn’t solve Darwin’s dilemma. Instead, they put one more nail in the coffin of Darwin’s attempt to salvage his theory from it. The truth is that “exceptionally preserved microbes” from the late Precambrian actually deepen Darwin’s dilemma, because they suggest that if there had been ancestors to the Cambrian phyla they would have been preserved.
I am willing to believe in evolution. But in order to get me to believe it, I insist on seeing a fossil record that shows the gradual emergence of phyla, one or two at a time, over hundreds of millions of years. That is what Darwinism predicts. We now have a solid record of what came before the Cambrian explosion. So where are the precursors? Where is the record of gradual emergence? Where is my evidence?
