Evolution?
The Cambrian Explosion
Explosion of specified complexity
The Cambrian explosion was the relatively rapid appearance (over a period of many millions of years), around 530 million years ago,
of most major animal phyla, as demonstrated in the fossil record...
The Cambrian explosion is the relatively short period in which many
complex life forms appeared on the planet.
It shows the sudden coming into existence of practically all known animal
phyla. The Cambrian
stratum also shows that there was a sudden and massive destruction of life
because of the preservation of large quantities of fossils.

The fossils from the Cambrian period can cause a real headache for evolutionary biologists.
Instinct tells us to expect simple organisms evolving over time to become increasingly more
complex.
However during the Cambrian period there was an apparent explosion of different major groups of animals, all appearing simultaneously in the
fossil record.
Equally challenging is answering why the Cambrian period provided such a rich interval for the redeployment of genes that led to more complex bodyplans.
The Cambrian explosion shows the appearance of all known phyla in a relatively short
timespan. With the Cambrian explosion for example
brains appear
which are considered the most complex organs of life.
The Cambrain explosion was an explosion of specified complexity which is another blow to evolution.

The Cambrian explosion has generated extensive scientific debate. The seemingly rapid appearance of
fossils in the "Primordial Strata" was noted
as early as the 1840s, and in 1859 Charles Darwin discussed it as one of the main objections that could be made against his theory of
evolution by
natural selection.
The abrupt manner in which whole groups of species suddenly appear in certain formations,
has been urged by several paleontologists, for instance, by
Agassiz,
Pictet, and by
none more forcibly than by Professor
Sedgwick, as a fatal objection to the
belief in the transmutation of species. If numerous species, belonging to the same genera
or families, have really started into life all at once, the fact would be fatal to the theory of
descent with
slow modification though
natural selection.
For the development of a group of forms, all of which have descended from some one progenitor,
must have been an extremely slow process; and the progenitors must have
lived long ages before their modified descendants.
Darwin himself warns that an event like the Cambrian explosion invalidates his theory.
In Darwin's time there was little knowledge from the period before the Cambrian explosion.
Darwin expected older strata to show fossils that would explain the sudden appearance of life in the Cambrian.
This is not the case, the Pre-Cambrian strata contain only few life forms. Thus the
gap is real.
Still, the evolutionists assume that there was a period of evolution
happening before it, from simple to complex life forms.
There is no true science to support that claim
and it is primarily based on the evolutionary worldview that presumes
evolution beforehand.
Another example of worldview over science.

The fossil record contains no trace of these preliminary stages in the development of
many-celled organisms.
The first clues to the existence of relatively advanced forms of life consist of a few barely discernible tracks, presumably made in
the primeval slime by soft, wriggling wormlike animals. These are found in rocks about one billion years old.
These meager remains are the earliest traces of many-celled animal life on the planet.
Biological structures were first recognized in the Longmyndian Supergroup more than 150 years ago where they were interpreted as body and trace fossils.
Despite a variety of interpretations through the years, many of these bedding plane markings are now recognized as biological and include
the sedimentary record of ancient
microbial mats at the sediment-water interface.
John Salter had therefore made the key discovery of life prior to the Cambrian radiation.
The Precambrian strata have been thoroughly examined by scientists since Darwin, but they contain very few
fossils with explanatory power.
The sudden appearance of phyla in the Cambrian poses
a serious threat to his theory of slow and gradual evolution.

One outstanding fact of the fossil record that many of you may not be aware of; that since the so called Cambrian explosion...
during which essentially all the anatomical designs of modern
multicellular life made their first appearance in the fossil record,
no new Phyla of animals have entered the fossil record.
And it has been the paleontologist—my own breed—who have been most responsible for
letting ideas dominate reality: ...
We paleontologist have said that the history of life supports that interpretation [gradual adaptive change], all the while knowing that it does not.
Why, in subsequent periods of great evolutionary activity when countless species, genera, and families arose,
have there been no new animal body plans produced, no new phyla? (Lewin, 1988)
After the Cambrian explosion no new phyla emerged. There are no
intermediates and no
macroevolution because from those Cambrian phyla all subspecies and variety came by means of
microevolution. Therefore evolutionists
Niles Eldredge and
Stephen Jay Gould invented
punctuated equilibrium, which contradicts Darwin's gradual evolution, in an attempt to safe there incredible
faith.

This rather sudden appearance, relatively speaking, of essentially all animal phyla during the Cambrian period is referred to as the 'Cambrian Explosion'.
After this period essentially no new phyla are thought to have evolved over the course of hundreds of millions of years.
Compared with the 35 or so animal phyla that still exist today, some people estimate that the Cambrian explosion may have generated as many as 100 different phyla.
The facts are that many phyla appeared in a relatively short period of time and that with time many phyla died out.
This is of course not in line with what evolutionists have always claimed.
There are many more burning scientific questions for evolution
than there are satisfying scientific answers from evolution.
That's due to the fact that science simply contradicts evolution.
Talk Origins Non Sense

complex animals about 540 million years ago,
but it was not the origin of complex life...

TalkOrigins is a fanatic evolution club sponsored by
mainstream science which of course tries to explain (away) the Cambrian explosion. However...
1. There is nothing seemingly about this sudden appearance. It was definitely sudden in the supposed evolution of billions of years. Nobody says it was the origin of complex life. But it was an explosion of specified complexity. This is certainly not in accordance with slow and gradual evolution as proposed by neo-Darwinism.
2. Transitional fossils are based on metaphysics, not science.
3. Plants existed before the Cambrian explosion. Algea for sure. But all known animal phyla appeared with the Cambrian explosion.
4. It is not. Scientists agree upon the timespan depending on what they want to include.
5. Anybody can make up just-so stories based on wishful thinking.
6. Of course, extinction events caused certain types to disappear. Living fossils prove that there was no evolution. Lazarus taxa show that so-called extinct life forms are still alive today. And of course microevolution caused variety.

None of the organisms mentioned by TalkOrigins
represent transitional precursors
to the forms that appear so abruptly during the Cambrian explosion.
Five to ten million years (which is the most likely time span) is extremely abrupt relative to the time that would be needed to accomplish those
radical innovations in animal form resulting in the origin of many different animal body types. ...
In summary, TalkOrigins has failed to provide us with a feasible
naturalistic explanation for the Cambrian explosion.
The facts that the article draws upon are either irrelevant to the subject at hand or accentuate the problem.
The Cambrian explosion continues to represent a formidable challenge to the
neo-Darwinian theory of
evolutionary gradualism.
The difficulty with "explaining the Cambrian explosion" efforts is that the explainers are not trying to explain it. They are trying to
explain it away.
That is a very different procedure. ... what we really hear from explainers away is a non-credible account that satisfies the
emotional needs of the people with a vested interest in avoiding the difficulty that the attested event presents to
Darwinism.
TalkOrigins doesn't explain, it tries to explain away.
This merely understates the problem for evolution theory.
