| "The RNA World"
The discovery in the 70s that the gasses originally
existing in the primitive world atmosphere rendered
amino acid synthesis impossible was a big blow to the
molecular evolutionary theory. It then was understood
that "primitive atmosphere experiments" of
evolutionists such as Miller, Fox and Ponnamperuma were
invalid. For this reason, in the 80s new evolutionist
attempts were put forth. As a result, the scenario of
the "RNA World" was advanced, which proposed
that it was not the proteins that were formed first,
but RNA molecules that contained the information for
the proteins.
According to this scenario advanced by Walter Gilbert,
a chemist from Harvard in 1986, billions of years ago
an RNA molecule that somehow managed to self-replicate,
formed by coincidence. Then this RNA molecule started
to produce proteins being activated by external effects.
Thereafter, it became necessary to store this information
in a second molecule, and somehow the DNA molecule emerged.
| CONFESSIONS
FROM EVOLUTIONISTS
Probabilistic calculations make it
clear that complex molecules such as proteins
and nucleic acids (RNA and DNA) could not ever
have been formed by chance independently of each
other. Yet evolutionists have to face the even
greater problem that all these complex molecules
have to coexist simultaneously in order for life
to exist at all. Evolutionary theory is utterly
confounded by this requirement. This is a point
on which some leading evolutionists have been
forced to confession. For instance, Stanley Miller's
and Francis Crick's close associate from the University
of San Diego California, reputable evolutionist
Dr. Leslie Orgel says:
It is extremely improbable that proteins
and nucleic acids, both of which are structurally
complex, arose spontaneously in the same place
at the same time. Yet it also seems impossible
to have one without the other. And so, at first
glance, one might have to conclude that life could
never, in fact, have originated by chemical means.1
The same fact is also admitted by
other scientists:
DNA cannot do its work, including
forming more DNA, without the help of catalytic
proteins, or enzymes. In short, proteins cannot
form without DNA, but neither can DNA form without
proteins.2 How did the Genetic Code, along with
the mechanisms for its translation (ribosomes
and RNAmolecules), originate? For the moment,
we will have to content ourselves with a sense
of wonder and awe, rather than with an answer.3

Being made up of a chain of impossibilities in
each and every stage, this hardly imaginable scenario
only magnified the problem and brought up many inextricable
questions rather than providing any explanation for
the origin of life:
1. When it is impossible to explain
the coincidental formation of even one of the nucleotides
making up RNA, how can it be possible for these imaginary
nucleotides to form RNA by coming together in a proper
sequence? Evolutionist biologist John Horgan admits
the impossibility of the chance formation of RNA as
follows;
As researchers continue to examine the RNA-world concept
closely, more problems emerge. How did RNA arise initially?
RNA and its components are difficult to synthesize in
a laboratory under the best of conditions, much less
under plausible ones.
2. Even if we suppose that it formed
by chance, how could this RNA made up of simply a nucleotide
chain have "decided" to self-replicate and
with what kind of a mechanism could it have carried
out this self-replicating process? Where did it find
the nucleotides it used while self-replicating? Even
evolutionist microbiologists Gerald Joyce and Leslie
Orgel express the desperateness of the situation in
their book titled "In the RNA World":
This discussion... has, in a sense, focused on a straw
man:the myth of a self-replicating RNA molecule that
arose de novo from a soup of random polynucleotides.
Not only is such a notion unrealistic in light of our
current understanding of prebiotic chemistry, but it
should strain the credulity of even an optimist's view
of RNA's catalytic potential.
3. Even if we suppose that there was
a self-replicating RNA in the primordial world, that
numerous amino acids of every type ready to be used
by RNA were available and that all of these impossibilities
somehow took place, the situation still does not lead
to the formation of even a single protein. For RNA only
includes information concerning the structure of proteins.
Amino acids, on the other hand, are raw materials. Nevertheless,
no mechanism exists to produce proteins. To consider
the existence of RNA sufficient for protein production
is as nonsensical as expecting a car to be self-assembled
and self-manufactured by simply throwing its design
drawn on paper on thousands of its parts piled upon
each other. In this case, too, production is out of
the question since no factory or workers are involved
in the process.
Transfer RNA. It binds to
amino acids and move them into place on the ribosome
as needed. Each type of tRNA binds only a single
one of the 20 different amino acids. Amino acids
attach to the appropriate tRNA at one end, which
has folded into a three-dimensional L-shape. Such
a perfect harmony taking place in an area one
billionth of a millimeter is clear evidence for
Creation. |
A protein is produced in the ribosome factory with
the help of many enzymes and as a result of extremely
complex processes within the cell. Ribosome is a complex
cell organelle made up of proteins. Therefore, this
situation also brings up another unreasonable supposition
that ribosome, too, should have come into existence
by chance at the same time. Even Nobel prize winner
Jacques Monod, who is one of the most fanatical defenders
of evolution, explains that protein synthesis can by
no means be underestimated so as to depend merely on
the information in the nucleic acids:
The code is meaningless unless translated. The modern
cell's translating machinery consists of at least fifty
macromolecular components which are themselves coded
in DNA: the code cannot be translated otherwise than
by products of translation. It is the modern expression
of omne vivum ex ovo (All life [is] from [an] egg). When and how did this circle become
closed? It is exceedingly difficult to imagine.
How could an RNA chain in the primordial world take
such a decision and what methods could it have employed
to realize protein production by undertaking the job
of fifty specialized particles only on its own? Evolutionists
have no answer to these questions.
Dr. Leslie Orgel |
Dr. Leslie Orgel, one of the associates of Stanley
Miller and Francis Crick from the University of San
Diego California, uses the term "scenario"
for the possibility of "the origination of life
through the RNA world". Orgel described what kind
of features this RNA had to have and how impossible
this was in her article titled "The Origin of Life"
published in American Scientist in October 1994:
This scenario could have occured, we noted, if prebiotic
RNA had two properties not evident today: A capacity
to replicate without the help of proteins and an ability
to catalyze every step of protein synthesis.
As should be clear, to expect these two complex and
extremely essential processes from a molecule like RNA
is only possible by an evolutionist's power of imagination
and viewpoint. Concrete scientific facts, on the other
hand, make it explicit that the thesis of the "RNA
World", which is a new model proposed for the chance
formation of life, is an equally implausible fable.
