[2005/08/15] Origin of Life Studies: Motion or Emotion?
Origin of Life Studies: Motion or Emotion? 08/15/2005 Harvard is going to fund origin-of-life research to the
tune of a million dollars a year, according to an AP release reported by
LiveScience.com,
MSNBC News and the Washington
Post. The goal is to reduce life¡¯s origin to a ¡°series of
logical events that could have taken place with no divine
intervention,¡± according to Harvard chemistry professor David Liu
(emphasis added in all quotes). Part of the motivation for this
initiative appears to be a counterattack to recent advances by the
intelligent design (ID) movement: MSNBC titled their copy, ¡°Harvard jumps
into evolution debate.¡±
Evolution is a fundamental
scientific theory that species evolved over millions of
years. It has been standard in most public school
science texts for decades but recently re-emerged in the spotlight as
communities and some states debated whether school children should
also be taught about creationism or intelligent design.... Scientists [sic] say that intelligent design, unlike
evolution, [sic] makes no scientific predictions and is
not testable, and so it is not a scientific theory
[sic]. Scientists [sic] freely admit they don¡¯t know
everything, but they cite the history of figuring things out
as evidence that mysteries do not imply divine, undecipherable
solutions. Harvard has not been seen as a leader in
origins of life research, but the university¡¯s vast resources could
change that perception.
Pro-evolutionists like Eugenie
Scott have usually tried to keep the issue of the origin of life in the
background, and treat it as a separate question. ID isn¡¯t letting
the issue get lost in the shadows. ID publications such as the
popular film Unlocking
the Mystery of Life are hoisting the issue into the limelight in
order to point out the inadequacy of naturalism to account for life at its
most fundamental level. This may be spurring evolutionists to
accelerate their efforts to show progress at most, or to look busy at
least, so as not to concede an important piece of territory to their
opponents. They know that if ID persuades enough people that life
required intelligence at the start for the first cell, then naturalism
risks appearing inadequate or even superfluous for explaining the origin
of birds, mammals, trees and all the rest by an unguided, mechanistic
process of natural selection. Though ID remains agnostic about
identity or nature of the intelligent cause, to permit a Designer, God or
undefined intelligence at any point would undermine the credibility of
naturalistic science to explain the entire history of the universe without
reference to divine intervention. One strategy is to
downplay the difficulty of the problem or portray it in easy-to-visualize
metaphorical language. In a recent press release, for instance, the
Geological Society
of America suggested that meteor impacts might have ¡°jump-started¡±
life. The evidence is strictly circumstantial: ¡°It¡¯s
interesting to note, says [Gordon] Osinski [Canadian Space Agency],
that on Earth the heaviest meteor bombardment of the planet
happened at about the same time as life is believed to have
started: around 3.8 billion years ago.¡± Another
strategy is to claim partial success. Three confident-looking young
scientists appeared in a recent press release from University
of Bath, with the title announcing, ¡°Scientists crack 40-year-old DNA
puzzle and point to ¡®hot soup¡¯ at the origin of life.¡± Actually, all
they did was hypothesize that life began with a two-letter DNA code, and
subsequently graduated to a three-letter code when a larger vocabulary of
amino acids became necessary. Yet at the very time their model
assumes the genetic code evolved naturally, the article points out that
the genetic code possesses qualities generally characteristic of designed
systems: translational integrity, robustness, optimization, and high
fidelity:
The theory also explains [sic] how the
structure of the genetic code maximises error tolerance.
For instance, ¡®slippage¡¯ in the translation process tends to
produce another amino acid with the same characteristics, and
explains why the DNA code is so good at maintaining its
integrity. ¡°This is important because these kinds
of mistakes can be fatal for an organism,¡± said [Jean] Dr van den
Elsen. ¡°None of the older theories can explain how this
error tolerant structure might [sic] have arisen [sic].¡±
It¡¯s not likely that the opponents of evolution will
be impressed by any of these three salvos, nor will retreat from pressing
their case that evolutionary theory is bankrupt when accounting for the
origin of life.
Not all motion is progress. It
might just be emotion, commotion, or self-promotion. Evolutionists
are generating a lot of commotion these days trying to find life¡¯s
potion in the ocean, with unmixed devotion to the notion that natural
causes can explain everything, even a Laotian. Harvard argues that
science has a history of solving problems without reference to divine
intervention. They think that by running faster they will get
there eventually, but what if they are running in circles? They
think that by investing more money they will win, but what if the
investment is a stock fraud? They think that by digging faster
they will find the buried treasure, but what if they have cordoned off
from consideration the very spot on the island where the treasure map
says it is buried? The claim that naturalism will
figure it out eventually, because science has a long history of figuring
out other mysterious phenomena, is a common argument from the
naturalists, so let¡¯s think about it a minute. It sounds
reasonable on the surface, but in essence, it is a belief based on extrapolation
and analogy.
All experiments in chemical evolution for 75 years have failed; in fact;
the situation is more hopeless now (follow the chain links on Origin of
Life) than it was when Oparin, and even Charlie himself, first
speculated about how the first cell might have come about in a soup of
chemicals. Obviously, a runner will never win if running backwards
away from the finish line, nor will a dogsledder reach the north pole
when the ice he is on is moving southward at a faster rate. A look
at history would appear to support the criticism that abiogenesis has
nearly been falsified already, when Pasteur with
his law of biogenesis disproved spontaneous generation. Chemistry
shows that molecules obey the laws of valence and mass action blindly
without purpose or direction. Physics shows that the laws of
thermodynamics are inviolable (yes, even in open systems and those far
from equilibrium), making systems tend toward disorder.
Information theory shows that communications are more likely corrupted
by natural causes, like interference and static, rather than generated
or improved. Clearly, the burden of proof is on the evolutionist
to overcome the hurdles erected by these robust laws of observational
science. To persuade philosophers or logicians that the
origin of life problem is tractable with reference to natural causes
alone, evolutionists need to establish at the outset that it is in the
same class of problem as explaining lightning or magnetism. After
all, these were considered occult forces by many in the past.
Magnetism, electricity and other examples of naturally-solved problems,
however, exhibit a fundamental difference: they are observable in the
present, and subject to testability and repeatability in the lab.
The origin of life, by contrast, was a one-time event that was not
observed by humans; evolutionists admit this. Even if biochemists
find a way to coax molecules to self-assemble into some sort of
self-replicating entity in the lab, they could never prove that¡¯s the
way it did happen on the early earth; they could only assert that
something similar might have happened. Opponents, however,
will undoubtedly criticize any successes as due to investigator
interference. Coaxing molecules to self-assemble is self-refuting,
because it applies intelligent selection to get results that were
supposed to come about without help from a mind. We¡¯re being very
magnanimous here. Anyone who has followed the chemical evolution
literature knows that biochemists face extremely daunting challenges, to
put it mildly.
Throwing money at the problem is likely to be as futile as gambling on a
race horse that is blind, deaf and crippled next to the ID
Seabiscuit. We know a lot more now about the gap
between chemicals – RNA, lipids, sugars and minerals – and the most
primitive living organism. We understand better the minimal
requirements for life. Even at a hypothetical level, evolutionists
cannot realistically imagine considering anything alive that did not
have, at the very least, a container, a metabolic system, and a genetic
code – each of which is extremely problematical to obtain from plausible
natural conditions. Moreover, the requirement for water and carbon
is universally acknowledged, setting constraints on the environmental
conditions, and few would dally with models that did not include RNA and
DNA – both highly improbable to emerge or survive under natural
conditions. Then there¡¯s the problem of homochirality, getting
molecules to be all one-handed – and these are just samples on a long
list of difficulties. That¡¯s why most of the hope stirred up in
the heydays of Miller, Sagan, Ponnamperuma and others has been abandoned
(except among TV animators) as reality has set in. One well-known
researcher recently admitted that the problems are almost enough to turn
one into a creationist.
Ribose, he said for instance – a basic ingredient of RNA (the
evolutionists¡¯ favorite starting molecule) – is hopelessly unstable
except in a desert with boron keeping it from falling apart – yet most
other researchers require RNA to be abundant in water when life
formed. Another said we need to start over with simpler
hypothetical molecules because the ones we know don¡¯t work; her own
research showed that amino acids degrade with hours under solar
radiation,
but the other argued that one cannot keep changing the basic molecules
without causing other problems. If the situation is so hopeless
now, and getting worse, despite all the latest lab techniques, at what
point will the chemical evolutionists decide that discretion is the
better part of valor? Dean Kenyon did, after all, and now embraces
intelligent design as the only plausible explanation.
The quest for the chemical evolution holy grail continues largely on the
assumption that science must seek natural explanations for things. But excluding intelligent causes by definition
makes no sense in archaeology, forensics, cryptography and SETI, so why
exclude them from biology? The very same methods used in these
other scientific activities can be used to infer design in a living
cell. Would it be reasonable to study the origin of Mt. Rushmore
by first ruling out sculptors, and restricting one¡¯s explanatory toolkit
to wind and erosion? The mountain is a ¡°natural¡± phenomenon, in
the sense of being made of rock, but the essence of the sculpture is not
the rock but the design. Similarly, the essence of a language is
not the paper and ink, nor the electrons hitting your terminal screen,
but the structure, syntax, and semantics of the message conveyed by an
intelligent agent. What is the difference with DNA? DNA¡¯s
function is not derivable from the sugars, phosphates and nucleotides of
which it is composed, but rather from the meaningful sequence of the
bases. The specific sequence cannot be predicted from first
principles, yet it is not random, because it produces function.
Moreover, that information is translated by molecular interpreters from
one language convention into another, entirely different code: the
protein code of amino acids. More astonishing, to guarantee the
message is not garbled, the cell constantly monitors its information
database with error-correction and editing machines. This
underscores the realization that DNA is, in fact, a language. It¡¯s
not just a metaphor that scientists speak of DNA as the ¡°language of
life¡±– that¡¯s really what it is. The comparison to computer
programming is even more apt. The scientific literature is replete
with references to molecular machines, functioning harmoniously in
robust networks programmed by codes written on informational
macromolecules; on top of everything else, it now appears that DNA is a
code regulated by another level of information. The
essence of life is information made flesh.
Information is the calling card of intelligent design. From our
uniform experience, every coded language comes from a mind. If
natural causes did not produce the Morse Code, or ASCII, why should
anyone assume they could have produced the DNA code? It is futile
to account only for the chemicals when information is the characteristic
ingredient. The logical approach to understanding a Rosetta Stone
is not to examine the minerals in the substrate, or tell stories about
how they might have coagulated into the shape of the stone with all its
markings. The logical approach is what Champollion did with the Rosetta
Stone: decipher the message with the presupposition that an
intelligent messenger, whoever it was, produced it with a purpose.
The only reason evolutionists abandon this approach in biology and
reject the clear design inference is their philosophical bias. The
result is a vain trust in inadequate causes. The quest
for a natural explanation of life¡¯s origin is reminiscent of the contest
between Elijah and the Baal worshipers on Mt. Carmel (see I
Kings 18). It would be interesting to see the expense report
from the priests of Baal. They certainly had the advantage of
numbers, for one thing, and must have thrown a lot of resources and
effort into the contest with Elijah. Their efforts bear some
similarity to today¡¯s contest to get the fire of life started
naturalistically, by force of hubris and commotion. There¡¯s the bluffing
element: ¡°we can do it without divine intervention.¡± There¡¯s the
shotgun approach of trying a lot of different methods.
There are the empty promises that they will figure it out in due time
(futureware), or that it¡¯s not that big a problem.
All such tactics resemble the bravado of the priests of Baal. On
the defensive side, they can always fall back on the accusation that
intelligent design is not science. This equivocation
is as arbitrary as if the priests of Baal were to disqualify Elijah¡¯s
method because it was not polytheistic. Elijah had a
strategy of his own. He let the priests of Baal do their
best. He gave them all day to shout, dance, pray, weep, cut
themselves and collapse. By sundown, after they were all bleeding
and panting from their doomed efforts, Elijah calmly gave a simple
invocation to the adequate cause. The fire not only came
instantly, it ¡°consumed the burnt sacrifice, and the wood and the stones
and the dust, and it licked up the water that was in the trench.¡±
This overkill demonstrated to everyone the contrast between adequate and
inadequate causes. That¡¯s why the intelligent design movement
doesn¡¯t need to throw a million dollars a year, nor a large number of
priests making a lot of racket, at the question of the origin of
life. It doesn¡¯t need a consensus, and it doesn¡¯t need
compromise. As an old preacher once said, ¡°you and God make a
majority in your community.¡±
