Science and creationism

[John Shuey]

A little background on science and the scientific method.  To be a "science" a discipline
must make predictions that are falsifiable.  This is the essence of science - laying out a
hypothesis and then testing it.

So consider the following 2 cases:

1.  An evolutionary biologist wants to test the idea that all arthropods are derived from a
common ancestor.  It true, then the theory predicts that there should be some very
conservative and complex traits that have been passed along almost unchanged from the
original ancestor to all its decedents.  Structural things like how legs are articulated, how
certain enzymes are patterned, what the exoskeleton is made of,  DNA sequences for particular
enzymes, mitochondrial RNA sequences, or even things like the chemical nature of the lipids
(waxes) found coating the exoskeleton.

Before (s)he starts looking at these structure though, (s)he make predictions pro and con
relative to the particular hypothesis being tested.  If the idea of a common ancestor is
correct, then there should be close similarities between many of these traits being
examined.  It the hypothesis is false, then there was no common ancestor between these
linages, and the traits would likely show no relationships.

Well, this particular hypotheses has been tested.

The reality is that crustaceans have very different exoskeletons and body chemistries than do
insects.  Likewise, spider legs are very different from millipedes and insects.  The specific
hypotheses is disproven.  If these taxa share a common ancestor, then they did so long before
the essence of "arthopody" evolved.  But the patterns they see patterns in parts of
arthropoda that are suggestive of common ancestry. The scientists discards the original
hypothesis, refines new hypotheses, and starts a new round of testing to see which ideas are
supported by the evidence and which are not.  Likely they note that millepedes, insects and a
few other groups seem to share many of the traits in question, so they start looking at more
complex traits, testing the hypothesis in a more rigorous manor.  If a hypothesis is true, it
will withstand attempts to disprove it.

2.  Now a "creation scientist" is interested in testing the same idea (only by definition,
they believe the null hypothesis to be true, and the original hypothesis is simply
impossible). "Creation science" discipline holds that a higher being created all life
denovo.  Hence, any perceived relationships in structure and chemistry are coincidental.  Any
lack of perceived relationships is coincidental.  From our perspective, what is, just is,
because that's the way it is.  So, the creation scientist can't really figure out how to
design a testable hypothesis, because creation science says that anything is possible because
God made it that way. You can't prove creation by looking at the things created, and you
can't disprove it either (unless its got a brand name sewn into the lining).  Everything and
every pattern observed, God made.

So this "scientist" looks at the differences between spider and insects legs and says " Wow,
God made them that way."  They note that the mitochondrial RNA in all arthropods is
incredibly similar (in fact in all animals) and they duly note, "Geeze, God made it that
way".  They note that crustaceans all have exoskeletons with calcium-based chemistry, and
insects all have chitin-based cuticles, and again the evidences very clearly indicates that,
"God made them that way".  In fact, it really doesn't matter what you look at, sub-atomic
particles, radioactive decay, RNA, or butterflies, God made them as he say fit.  (Then the
"scientist" gets distracted by the color of the ink in their pen, and they grab a different
pen and look at it.  They marvel in the intricacies of their God, that could create so many
different colors of ink for them to enjoy.  Soon they have new insights into the marvel of
their religion and the supreme being that created everything in all his infinite wisdom).
Marvel, revel, revel, marvel...

Thus the very definition of science and the scientific method - formulating and testing
hypotheses - is impossible with "creation science" because is makes no predictions that can
be tested.  Everything that is, God made that way.

Thus, "creation science" is is not science - it is adherence to dogma.  As science goes, it
is indeed fraud.

Now note that religion is not science, nor was it ever intended to be.  Many of the best
evolutionary biologists that I knew in grad school had religious affiliations, usually but
not always Christian.  I even know one that teaches at Liberty (Baptist) University - which
is a pretty good testament that christian faith and evolutionary theory are not incompatible
to the sophisticated mind.

And don't even get me started on Occam's razor relative to ad-hoc religious explanations.

    . "What can be done with fewer assumptions is done in vain with more".

This simple idea articulated over 700 years ago, underlies all modern scientific modeling and
theory building. The elegance of evolutionary theory is that one (albeit complex) theory
explains life on Earth and makes such powerful predictions (ranging from butterfly mimicry to
the mode of action for new drugs) that it considered the unifying theory of biology.  Or if
you prefer, you can invoke somewhere between 2,500,000 and 20,000,000 separate creations
events during a 7 day period.

Just don't call it science.
