PRELIMINARIES
WHY THIS TALK?
-- To Celebrate the Triumph of Science in its Great Achievement:
Unfolding the Creation Narrative
-- To Challenge the Triumphalism of Science
 To Counterbalance this with the findings of Science Itself.
“I must confess that I was at first startled and alarmed by
rumours of changes and discoveries which, I was told, were to
overturn at once the science of geology as hitherto received,
and all the evidences which had been drawn from it in favour
of revealed religion… God with us, in the world of science
henceforth to be no more!”
Lydia Miller, 1869*
… She concluded the evidences are
still there but "removed into a more
distant and dimmer region.”

PRELIMINARIES
SHARP POINTS
"A common sense interpretation of the facts suggests that a
super intellect has monkeyed with physics, as well as with
chemistry and biology, and that there are no blind forces
worth speaking about in nature. The numbers one
calculates from the facts seem to me so overwhelming as to
put this conclusion almost beyond question.”
Fred Hoyle, 1980

CREATION NARRATIVE
A Hospitable Environment and the First Life
 Life Itself built the hospitable environment!!
Summary time budget for building a hospital environment:
Total time: ± 4 Billion years (BY)
± 0.5 BY from earth formation to the first Bacteria
– Cooled earth, oceans.
± 2.0 BY more to first Eukaryotes (Oxygen based)
– Oxygen atmosphere ready
± 1.5 BY more to first ocean animals
– Waste food (nitrogen) in place
± 0.2 BY more to first land plants and animals
– Ozone filter in place
18
CREATION NARRATIVE
A Hospitable Environment and the First Life
 Life Itself built the hospitable environment!!
 The Oxygen atmosphere is the result of life.
 The available Nitrogen to support life is the result of life!
“The existence of large amounts of oxygen in a planet's
atmosphere would be a strong indicator of life.”
NASA

CREATION NARRATIVE – The Creation of Life
THE SECOND GENESIS:
CREATION OF LIFE ITSELF
 Bacterial Life arose on earth at the earliest possible time.
As soon as the Earth had cooled and stabilized
- 3.9 to 4.0 BY ago. Evidence: C-13/C-12 ratio in old rocks.
 Even the "simplest" life is vastly complex.

CREATION NARRATIVE – The Creation of Life 3
THE COMPLEXITY OF LIFE
Must have machinery to process its genetic information
Called the CENTRAL DOGMA – every cell does it!
[See the handout reproduced on the next slides]
22
CREATION NARRATIVE – The Creation of Life (Handout)
THE CENTRAL DOGMA - 1
• DNA. The genetic information is recorded in long ladder-like molecules of DNA. Each rung of
the ladder (a base pair) is a pair of 4 short molecules called nucleotides A,T,C and G. They
always pair in the same way: A (adenine) pairs with T (thymine), and C (cytosine) pairs with G
(guanine). The sides of the ladder are sugar molecules strung end-on-end. The size of the DNA
is expressed in the number of base pairs.
A Codon is a triplet of base pairs. Each codon corresponds to one of twenty Amino acids -- it’s
the amino acids that are the building-blocks of proteins, which do the work of the cell.
23
CREATION NARRATIVE – The Creation of Life (Handout)
THE CENTRAL DOGMA - 1
Translation. To every codon there is a special molecule called tRNA
that has that codon on one end and has its associated amino acid
attached to the opposite end. A given codon (virtually) always
associates with the same amino acid -- across all species. Generally a
cell must have at least 30 different tRNA molecules to make its
proteins; each tRNA must have the genes to build itself as part of the
cell's DNA. Some genes code for RNA molecules -- such as tRNA -rather than proteins. There are many RNA molecules used in
regulation.
A gene is a sequence of codons. Each gene corresponds to a
particular protein that is used by the cell to do its work.
24
CREATION NARRATIVE – The Creation of Life (Handout)
THE CENTRAL DOGMA - 2
• Regulatory Molecules. Hanging around the cell's DNA are a number of molecules -RNA polymerases, repressors and other regulatory molecules that determine if, when and
how often a given gene will be copied to make proteins. These molecules are part of a
complex regulatory system that is an essential for reading the DNA. Without this regulatory
apparatus -- which may be as complex as the DNA itself -- the DNA is useless.
Regulatory Molecules around DNA
25
CREATION NARRATIVE – The Creation of Life (Handout)
THE CENTRAL DOGMA - 3
• Messenger RNA. When a given gene is to be copied, the rungs of the DNA ladder split and
the left-half is copied into a messenger molecule called mRNA. After error checking and
correcting, this mRNA moves away from the DNA and out of the nucleus to the main part of the
cell to begin making proteins.
26
CREATION NARRATIVE – The Creation of Life (Handout)
THE CENTRAL DOGMA - 4
• Ribosomes. Complex motor molecules called ribosomes surround the mRNA chain and
begin to transcribe the codons and build an amino acid chain that will be the future protein. This
is done by matching a tRNA molecule to a codon, and then detaching the amino acid and
adding it to the building chain. Every living species from the simplest to the most complex
requires these complex ribosome motors to carry out gene processing.
27
CREATION NARRATIVE – The Creation of Life (Handout)
THE CENTRAL DOGMA - 5
It takes over 50 genes just to form the ribosomes. See the Wikipedia article on
ribosome biogenesis.
• Folding. Once the protein chain is complete, it then detaches from the ribosome and
folds into the shape that it must have to carry out that protein's specific function.
Generally this folding uses other helping molecules called chaperones, that guide it to
make the correct shape.
28
CREATION NARRATIVE – The Creation of Life 4
THE COMPLEXITY OF LIFE
EVERY Living Cell carries out the same “Central Dogma”
Around 200 genes are required just to build this complex
machinery.

The Eigen Paradox
The Levinthau Paradox
The Regulatory Paradox.
31
CREATION NARRATIVE – The Creation of Life 5
PARADOXES IN THE CREATION OF LIFE
 The
Combinatoric Paradox
-- Wistar Institute Conference (1966)
“Mathematical Challenges to the Neo-Darwinian Interpretation
Of Evolution” (Wistar Institute Monogram No. 5, 1967).
"It is our contention that if 'random' is given a serious and
crucial interpretation from a probabilistic point of view, the
randomness postulate is highly implausible …."
Murray Eden, Inadequacies of Neo-Darwinian Evolution as a Scientific Theory
Wistar Institute Symposium, 1966, p. 109

PARADOXES IN THE CREATION OF LIFE
 The
Combinatoric Paradox
-- Wistar Institute Conference (1966)
“Mathematical Challenges to the Neo-Darwinian Interpretation
Of Evolution” (Wistar Institute Monogram No. 5, 1967).
 Thus, if natural evolution did occur then the only plausible
conclusion is that it occurred as a result of some (to date
unknown) natural laws.
33
CREATION NARRATIVE – The Creation of Life 5
PARADOXES IN THE CREATION OF LIFE
 The
Combinatoric Paradox
Four Responses:
1. Perhaps Life came here from outer space?
2. Infinity of Universes Argument: Any event, no matter how
improbable, will surely occur given enough universes.
Reply: Abuse of concept of infinity – It can be used to justify
the repeated recurrence of any event, however low the probability.
Are there an infinite number of universes with a Dr. David C.
Bossard giving lectures on the Creation Narrative?
3. Build big by starting small and combining them.
Reply: The Fallacy of Betting Systems – "there is no
combination or betting system that will turn the odds into your
favour." The odds of getting a very low probability result cannot be
helped by any “system”.
34
CREATION NARRATIVE – The Creation of Life 5
PARADOXES IN THE CREATION OF LIFE
 The
Combinatoric Paradox
Four Responses:
4. There Must be Unknown Natural Laws.
Reply: Then spend your time finding them, instead of writing
books that make the lazy argument that Evolution is Fact not
Theory.
Note: Promising research is being done in this direction in the new
science of Evolutionary Development (EvoDevo for short). However this
research is directed to modifying existing gene expression, not to
creating genes in the first place.
35
CREATION NARRATIVE – The Creation of Life 6
PARADOXES IN THE CREATION OF LIFE
 The
Eigen Paradox*
A gene with over 100 base pairs must be accompanied by
error-correction code (also encoded in genes) that is
more complex than the original gene.
 The implication is that it is impractical to try to “bootstrap”
the building of large functional genes by random,
undirected processes.
36
CREATION NARRATIVE – The Creation of Life 7
PARADOXES IN THE CREATION OF LIFE
 The
Levinthal Paradox
A large protein can fold in countless ways, most of which
by necessity have never been tried in the entire life of the
universe. There is no obvious biological way to predetermine a particular folding without the help of
“chaperone” proteins. So how do proteins (or the life
systems) “know” how to fold?

The Creation of Plants and Animals
"The magnates walk first*."
Hugh Miller (1858)
"We know, further, so far at least as we have yet succeeded in
deciphering the record, -- that the several dynasties were
introduced, not in their lower, but in their higher forms; that, in
short, in the imposing programme of creation it was arranged,
as a general rule, that in each of the great divisions of the
procession the magnates should walk first."
