There are so many of these stories now: From ScienceDaily:

One of the most exciting discoveries in genome research was that the last common ancestor of all multicellular animals — which lived about 600 million years ago — already possessed an extremely complex genome.

Hold on. What does that mean, exactly?

Using comparative genomic analyses, the researchers reconstructed evolutionarily conserved gene arrangements in animals and investigated their activity in different cell types. They could show that genes that are always present together in the genome in several species, also tend to be active in the same cells. For example, three genes that have been adjacent in several species (e.g., in sponges or cnidarians) for 600 million years are primarily active in a digestive cell type. “Cell types in animals can thus be characterized not only by individual genes but also by specific gene arrangements, and different cell types are also capable of accessing different regions in the genome,” explains Oleg Simakov, evolutionary biologist at the University of Vienna. In addition, the team noted that certain cell types seem to utilize such conserved regions more than others, and thus may represent very ancestral functions. Paper.

So if all this complexity got started in something like the twinkling of an eye, are we looking at an argument for creationism? Or what? What exactly is the source of all this very complex, very early information?

    Evolution that takes no time is not evolution. Or if you prefer to think of evolution as simply change, then it is spontaneous evolution, instantaneous evolution, indistinguishable from magic, miracles, or divine intervention. This word is being stretched to cover just about anything and everything. But the one thing it cannot mean, is “gradual change due to chance improvements in a fitness landscape”. In other words, the one sense it cannot have is the sense in which Darwin used it.

    Re. the Cambrian Explosion. The hardline Darwinists are forced to surmise that magically, somewhere in the oceans, for many hundreds of millions of years prior to the Explosion there was a very large population of gradually evolving primitive Precambrian fauna that somehow completely escaped fossilization. Despite there having been in the Precambrian plenty of similar environments to those that later produced the Cambrian soft-bodied fossiliferous beds such as the Burgess Shale and similar formations in China for instance.

    Or, that this slowly evolving Precambrian population of pre-arthropods, pre-vertebrates, etc. was in truth fossilized but absolutely all of these fossils were later somehow magically destroyed by some sort of unknown unseen geological processes, processes that just happened to stop at the Cambrian boundary.

    Darwinists sure are fond of magical thinking to rescue their quasi-religious ideology. Like (with one popular theory) imagining that a rapid rise in sea oxygen levels somehow magically stimulated the sudden appearance of very many new multicellular animal phyla, without the long gradual Darwinistic process that their theory presupposes.
