If you are wanting to do more reading on this subject, than this article might help. (I personally don't subscribe to the millions of years spoken of here, but that is often assumed in these discussions)
Hello all, I'm looking to see what the latest is on the Cambrian Explosion in terms of creation/evolution research. I know it corresponds well with creation day 5 from a creationistic point of view, but that recently there have also been some papers suggesting that the Cambrian Explosion actually does verify evolutionary theory. All the same I am struggling to see how new discoveries of soft-bodied invertebrates in the Edicaran suddenly explains the explosion of 50-80% of all animal phyla ever (including a few vertebrates) to ever exist.
I have heard the argument that invertebrates likely had quicker turn-around times generationally, which is what allowed things like trilobites to so quickly diversify, but seeing as how so many creatures suddenly started fitting into niches that had never been populated before (or even existed if we look at things like the erosion associated with the Great Unconformity and its affects on the ocean), an example would be both benthic and pelagic environments being inhabited all at once during the Cambrian, I am struggling to see how this theory works.
I'm a little all over the place I know (I'm tired...), but I'm debating an evolutionist over the subject and am wanting to hear from those more knowledgeable than myself here.
Thanks,
