The Cambrian explosion


This is not about any kind of fireworks, but about something that greatly troubled Darwin. This is because of the marked difference of the number and types of fossils found in the lowest level of the geologic column called the Precambrian and the next higher level called the Cambrian.

In the Precambrian layer there were only three phyla represented, and these are mainly one-celled organisms. Whereas in the Cambrian there were 19 phyla and they were much more complex and advanced than those in the lower level. The phyla are the next highest level in the taxonomic scale, which has been devised to show the natural relationships of all the organisms on earth.

Here is Darwin’s concern: “But just in proportion as this process of extermination has acted on an enormous scale, so must the number of varieties, which have formerly existed on the Earth, be truly enormous. Why then is not every geological formation and every stratum full of such intermediate links? Geology assuredly does not reveal any such finely graduated organic chain, and this, perhaps, is the most obvious and gravest which can be urged against my theory. “

Basically he has recognized the fossil record does not have the many intermediate or transitional forms that should be present to explain the abrupt appearance of major fossil plants and animals. This looks more like creation by God than the gradual development that the evolutionists propose in order to accommodate the virtually impossible events needed for producing the varied and complex life forms found in the Cambrian layer.

Evolutionists also make big claims that the animals have many of the same anatomical features as well as other body systems, blood compositions and organs that maintain the equilibrium of the body as humans, and that these show we all have evolved from common ancestors.

They overlook the possibility this similarity is just an indication they are the work of a Master Designer — the Creator — who shaped the members of these groups according to certain basic plans of structure.

If someone were to look at a Boeing 747 and claim it evolved from what the Wright brothers flew it would be more correct to say there are certain basic elements that planes need in order to fly.

The existence of a question for which we don't yet have a scientifically valid answer does not mean therefore: it must be God! Really?

For example, the evolution of active predators in the late Precambrian could have spurred coevolution of hard parts on and larger size of other animals, in an offensive and defensive arms race below the seas. Hard parts fossilize much more readily than soft parts, leading to many more fossils but not necessarily more animals. Planktonic grazers began producing fecal pellets that fell to the bottom of the ocean rapidly, profoundly oxygenating the seas and providing the fuel that hungry predators needed to chase their prospective meals, or for the hunted to flee. The early Cambrian followed a period when earth was a snowball in space. Much life perished then. When the ice melted away, the surviving life had a milieu of genetic diversity, just the stuff on which selective pressures could act to create new and wonderful life forms.
