Are you not agreeing then that a period of at least some millions of years was involved, which means that there is no reason to jump to any conclusion that anything happened spontaneously or miraculously.http://www.evolutionnews.org/2013/07/how_sudden_was_074511.html
"How "Sudden" Was the Cambrian Explosion? "
"Instead, he equates the Cambrian explosion with the most explosive period of the Cambrian radiation (as most Cambrian experts do) in which the vast majority of the higher taxa arose. He asserts specifically that the re-dating of critical Cambrian strata in 1993 established that the strata documenting the first appearance of the majority of the Cambrian phyla and classes took place within a 10 million year period -- a period Meyer does equate with "the explosion of novel Cambrian animal forms." (pp. 71-72) As he describes it, "these studies [i.e., radiometric analyses of zircon crystals in Siberian rocks] also suggested that the explosion of novel Cambrian animal forms" took about 10 million years. (p. 71)"
"An analysis by MIT geochronologist Samuel Bowring has shown that the main pulse of Cambrian morphological innovation occurred in a sedimentary sequence spanning no more than 6 million years. Yet during this time representatives of at least sixteen completely novel phyla and about thirty classes first appeared in the rock record. In a more recent paper using a slightly different dating scheme, Douglas Erwin and colleagues similarly show that thirteen new phyla appear in a roughly 6-million-year window. (p. 73)"
Read it all for yourself, but allowing for dating errors, it was simultaneous.
Clearly there is every reason to suppose that if new niches existed at the time that hard bodies were being developed for the first time for both attack and defence then many new lines of evolution would have been going on simultaneously, free from any existing and probably more effective opposition.
This isn't about creation, it's about evolution, right?
