Hi John—
Your
critique of the Dawkins weasel demonstration found its way to me, and I agree
with it entirely. I offered my own critique in Undeniable (p198-200). You hit the nail on
the head!
Regrettably,
even solid refutations of evolutionary arguments like this don’t seem to get
their proponents to rethink their position. I’ve become convinced that this is
because the root problem is spiritual, not scientific or intellectual.
Best
regards,

In chapter 3
of his book The Blind Watchmaker, biologist Richard Dawkins gave
the following introduction to the program, referencing the well-known infinite
monkey theorem.*
I don't know
who it was first pointed out that, given enough time, a monkey bashing away at random
on a typewriter could produce all the works of Shakespeare. The operative
phrase is, of course, given enough time. Let us limit the task facing our
monkey somewhat. Suppose that he has to produce, not the complete works of
Shakespeare but just the short sentence 'Methinks it is like a weasel', and we
shall make it relatively easy by giving him a typewriter with a restricted
keyboard, one with just the 26 (capital) letters, and a space bar. How long
will he take to write this one little sentence?
[NOTE: How lazy of Richard
Dawkins to fail to look up the author of his monkey business. It was Sir Arthur Eddington.
In 1928, British astrophysicist Arthur Eddington presented a
classical illustration of chance in his book, The Nature of the Physical
World: “If I let my fingers wander idly over the keys of a typewriter it
might happen that my screed made an intelligible sentence. If an army of
monkeys were strumming on typewriters they might write all the books in
the British Museum.”
This is nonsense compounding nonsense. And yet my high school math teacher presented
this proposition to his classes in the 1960’s.
First, an “army of monkeys” wouldn’t be very interested in hitting
typewriter keys repeatedly. There is
nothing for them to gain in so doing.
Second, those who did hit the keys would quickly get to the end of
the line, and have no concept of returning the carriage to type the second
line.
Third, those very few who somehow overcame the first and second
hurdles, repeatedly, would find that the paper was ejected from the carriage,
and they are hopelessly unable to replace the first page with a fresh sheet of
paper.
Fourth, we will never get to the fourth problem of exhausting the
ink in the typewriter ribbons because the “army of monkeys” would have
defecated on or otherwise ruined every typewriter.
Fifth, Sir Arthur Eddington never began to consider the statistics
of monkeys “selecting” 1 out of approximately 100 different keys, counting
upper and lower case of all letters, numbers, and punctuation marks. A page of an average book has 250 – 300
words. (https://hotghostwriter.com/blogs/blog/novel-length-how-long-is-long-enough)
*Finally, the largest army in the world is the People’s Liberation
Army of Communist China, with over 2,000,000 troops. This is hardly “infinite” in number. (https://economictimes.indiatimes.com/)
The average word has 6.47 letters. (https://capitalizemytitle.com/character-count/100-characters/)
Using the lower value of 250 words, times 6.47 letters equals 1,617
characters in a page.
1/100 to the 1,617th power is 10-3,234, for
just one page, much less “all the books in the British Museum.”
“we just think of one chance in 10 to the 40th power”
as “impossible”. – Richard Dawkins, (The Blind Watchmaker, page 142)
Emil Borel, a famous statistician, defined “impossible” as an event
with a probability of 10-50 or less.

This is equivalent to finding one unique marble, in 3,740,000
billion billion spheres the size of earth, all full of identical marbles except
for one, on your first and only attempt. You do not get an infinite
number of attempts, not even two.
Calculations:
Whereas 105 marbles are in 1 kilometer, when identical spheres are stacked, they drop into the valley of three other spheres, which reduces their equivalent cubic volume to 74% of their diameter.
Therefore, the volume of 105 marbles cubed equals (.74 x 105) cubed = .405 cubic kilometer per 1015 marbles
1050 marbles have 1035 times the volume of 1015 marbles = .405 x 1035 cubic kilometers.
The volume of earth is 108.3 x 1010cubic kilometers. **
4.05 x 1034 cubic km divided by 1.083 x 1010 cubic
kilometers/earth = 3.74 x 1024 volumes the size of earth.
Therefore 1050 marbles would fill 3,740,000 billion billion) earth-size spheres full to search and find the unique marble on your first and only try. Personally, I would call it impossible to find that unique marble in just one earth-sized sphere full of them.

Dawkins then goes on to show that a process of
cumulative selection can take far fewer steps to reach any given target.
In Dawkins' words:
We again use
our computer monkey, but with a crucial difference in its program. It again begins
by choosing a random sequence of 28 letters, just as before ... it duplicates
it repeatedly, but with a certain chance of random error – 'mutation' – in the
copying. The computer examines the mutant nonsense phrases, the 'progeny' of
the original phrase, and chooses the one which, however slightly, most
resembles the target phrase, METHINKS IT IS LIKE A WEASEL.

Generation 02: WDLTMNLT DTJBSWIRZREZLMQCO P
Generation 10: MDLDMNLS ITJISWHRZREZ MECS P

Generation 30: METHINGS IT ISWLIKE B WECSEL
Generation 40: METHINKS IT IS LIKE I WEASEL
Generation 43: METHINKS IT IS LIKE A WEASEL
Dawkins
continues:
The exact
time taken by the computer to reach the target doesn't matter. If you want to
know, it completed the whole exercise for me, the first time, while I was out
to lunch. It took about half an hour. (Computer enthusiasts may think this
unduly slow. The reason is that the program was written in BASIC, a sort of
computer baby-talk. When I rewrote it in Pascal, it took 11 seconds.) Computers
are a bit faster at this kind of thing than monkeys, but the difference really
isn't significant. What matters is the difference between the time taken by
cumulative selection, and the time which the same computer, working flat
out at the same rate, would take to reach the target phrase if it were forced
to use the other procedure of single-step selection: about a million
million million million million years. This is more than a million million
million times as long as the universe has so far existed.
[So much for Dawkins’ specious argument in defense of Darwinism,
which he proudly claimed, “… made it possible to be an intellectually fulfilled
atheist.” (http://UncommonDescent.com) Twenty-six capital
letters plus the space bar equals twenty-seven. Twenty-seven to the
twenty-eighth power equals ten to the fortieth different possible combinations,
of which we seek only one specifically.
Dawkins admits his definition of “impossible” is 1 chance in 10 to the
40th power. This is not for
all of Shakespeare’s works, but for one short sentence, and even then on a
dramatically altered keyboard, not of fifty possible keys, lower case, and
fifty more keys, upper case, but for only twenty-six keys, all upper case.
Of critical but neglected importance is the fact that for
“selection” to occur, the intermediary produced by the random mutation MUST
confer a “selective advantage” for the host organism, otherwise it will be
lost. It is therefore incumbent on
the advocate for Darwinism to demonstrate, in each case, what that improvement
is and how it operates, every single time, without exception. “Selection” requires no less. This is easily done when copying short
sentences, but not so easily done when originally constructing over 20,000 proteins
in humansa, the largest of which is titin, at 38,138b
amino acid residues in length. 1 out of 20 amino acids “selected” consecutively
38,138 times has a probability of 1 chance in 1049,618. This is for only one protein. Calculating for
chirality, i.e. the “selection” of L amino acids instead of D amino acidsc
and all peptide bonds rather than the equally probable non-peptide bondsd
reduces the probability of original naturalistic synthesis to 1 chance in 1072,578. Twenty thousand more proteins to go! ]
