The Cambrian Explosion

THE CAMBRIAN EXPLOSION

Having read a great deal about this ‘explosion’ I want to put before the expanding readership some little facts that they may not know. These facts show that it is far beyond the bounds of credibility for so many, and such varied organisms to have evolved in any step by step fashion. Simply because they appeared so suddenly and in one fell swoop.

This obviously bothered Darwin, and later on, Gould and many other palaeontologists.

There is no credible evolutionary explanation of the phenomenon, and I am amazed to know that so many informed people (on the subject of the Cambrian explosion, I mean) can look at those facts in the face, and still go along with the ToE.

What does ‘Cambrian’ mean?

Palaeontologists dig down into the earth’s crust, and they have found that there are many layers of rock. They’ve given the layers names, and the names depend on the kind of fossils in the rock.

The oldest animals/ plants are in the deepest layers, which are the oldest ones, and the newest animals/plants are in the highest ones.

Right at the very bottom of the layers is granite, which cannot and does not contain fossils, and is the oldest of the rocks.

So imagine a pack of cards resting on a granite surface. The granite represents the basement layer of rocks and piled on top of it are the cards, each of which represents a layer of rock. The layer resting on the granite is called the ‘Pre-Cambrian’ layer, and contains a very limited number of fossils: limited both in number and kind.

The layer on top of that one is the ‘Cambrian’ layer, and it is this one we are going to discuss in brief.

What’s in the Cambrian Layer?

To everybody’s astonishment, especially the people who believed in the gradual evolution theory, there are thousands of different kinds of animals and plants in that layer, and they weren’t simple ones either.

Here’s a quote that shows this: http://science.enotes.com/earth-science/cambrian-period. My comments in square brackets.

“…In these strata, the earliest known chordate (spinal cord-bearing animal), Pikaia, was first found.

[It was a pretty complex animal, reminiscent of Amphioxus, a chordate studied still, and living still today.]

Based on the obvious and regular segmentation of the body, Walcott classified it as a Polychaete worm. It resembles a living chordate commonly known as the lancelet and perhaps swam much like an eel.

Other marine creatures of Cambrian seas included the archaeocyathids and stromatoporoids (two extinct, sponge-like organisms that formed reefs),

primitive sponges and corals,

simple pelecypods and brachiopods (two kinds of bivalves),

simple molluscs, http://www.palaeos.com/Invertebrates...lacophora.html

primitive echinoderms

and jawless fishes, [they may be jawless, but they are distinctly still fish!]

nautiloids, and a diverse group of early arthropods (including many species of trilobites).

Trilobites were particularly abundant and diverse, and over 600 genera of Cambrian trilobites are known.

Some species of trilobites were the first organisms to develop complex eye structures.

[This guy has just got to be joking. Note the foolish comment ‘to develop complex eye structures’! As if they were all previously lurking around blindly, carrying out experiments trying to improve some duff eye structure or the other! Not at all. The eye of the trilobite appears fully formed, and fully complex.

It contains calcium sulphate, which some claim is of the correct refractive index to correct spherical aberration, no less! Spherical aberration was only solved by Joseph Lister in 1830, the problem having been noted since the construction of the telescope by Galileo and others.]

Numerous Cambrian reefs, patch reefs, and shallow-water mounds were formed by stromatolites, a layered mass of sediment formed by the daily trapping and binding action of a symbiotic growth of blue-green algae and bacteria.”

This is only a cursory look at the Cambrian. Gould’s Wonderful Life goes into considerable detail on the subject, and is well worth a read, if only to amaze yourself, and provoke the question in your mind: how the dickens did all this evolve so suddenly?

Or, did they evolve?
