Glad you are looking into the sham called 'Darwinian theory.'
Evolution Theory. What did Darwin know about the Cambrian Era?
The
sudden change of the Cambrian Era was, in relative terms, not too sudden for the process of evolution. The changes during the Cambrian Era did not occur over decades, centuries, or even thousands of years; they occurred over millions of years—plenty of time for evolutionary change. However, for millions of years beforehand, body plans of animals had remained relatively constant. Not until this time period did a significant change occur. The remaining questions are:
What triggered the Cambrian Explosion? And why did so much change occur at this time? Several different theories address the origin of the Cambrian Explosion, proposing that dramatic environmental changes must have opened up new niches for natural selection to operate upon.....
While the causes of the Cambrian Explosion remain a topic of open and exciting debate, the continued fossil discoveries from the Cambrian and Precambrian Eras are bringing more clarity to the evolutionary puzzle. These fossils provide valuable insight, particularly for envisioning the common ancestors of diverse groups. For instance, both vertebrates (fish) and echinoderms (sea urchins, starfish) are part of the group called
deuterostomes. Without fossil evidence, it is hard to envision what a common ancestor would look like for these very different creatures. The Cambrian fossils are filling in the picture.14"

Time to teach you a new word: Spin.
Spin…altering the truth without altering the facts.
You've just fallen for the secularist's spin.
The Final Nail in Darwinism's Coffin
1. . "THE ABRUPT manner in which whole groups of species suddenly appear in certain formations, has been urged by several palæontologists—for instance, by Agassiz, Pictet, and Sedgwick—as a fatal objection to the belief in the transmutation of species. If numerous species, belonging to the same genera or families, have really started into life at once, the fact would be fatal to the theory of evolution through natural selection."
Darwin, "On The Origin of Species," p.302
a. So Charles Darwin named the Litmus Test for his theory: see if new species arise gradually, or spontaneously. If the former, he's a winner....but if the latter....well...
2. The discovery of the Burgess Shale deposits pretty much nailed it. The significance of the Burgess Shale discoveries is that the many new body plans show disparity, major differences that separate phyla, classes and orders ....and careful study of earlier fossils did not reveal any evolutionary trail!
