I’ve also examined more recent evolutionary theories and shown why they too fail to explain key aspects of the evidence. To this point, then, much of the evidence has returned a negative verdict. It has told us a lot about what, in all probability, did not cause the Cambrian explosion. But, as in our hypothetical murder case, an accumulating body of evidence that makes one set of explanations less and less plausible may also begin to paint a picture of an alternative cause and the true explanation.
