And from that same Wiki article --<quoted text>
Please present your fossil proof of evolution. Funny that you have this proof and science does not. There is no known fossil of one kind of animal giving birth to another kind of animal.
"The long-running puzzlement about the appearance of the Cambrian fauna, seemingly abruptly and from nowhere, centers on three key points: whether there really was a mass diversification of complex organisms over a relatively short period of time during the early Cambrian; what might have caused such rapid change; and what it would imply about the origin and evolution of animals. Interpretation is difficult due to a limited supply of evidence, based mainly on an incomplete fossil record and chemical signatures remaining in Cambrian rocks."
"analysis shows that the Cambrian explosion was no faster than any of the other radiations in animals' history." ... "recent research has overthrown the once-popular idea that disparity was exceptionally high throughout the Cambrian, before subsequently decreasing. In fact, disparity remains relatively low throughout the Cambrian, with modern levels of disparity only attained after the early Ordovician radiation."
