Evolution:
Fact
or Faith?
By
John Halford
How
good is the evidence that life evolved naturally, without a Creator?
the
first verse of the Bible tells us, “In the beginning God created the
heavens and the earth.” It does not tell us precisely how he did it.
It
is “by faith we understand that the universe was formed at
God’s command, so that what is seen was not made out of what was
visible” (Hebrews 11:3).
God
out of the picture
Many
of us are quite happy to leave it there – a matter of faith. But
others seek a scientific explanation for the origin of the universe
and the subsequent development of millions of life-forms. There is
nothing necessarily wrong with this. Scientific discovery and biblical
revelation do not have to be in conflict. Unless, that is, science
leaves God out of the picture.
Unfortunately,
the commonly accepted scientific explanation for the origin and
development of life—the theory of evolution—does leave God out.
The theory proposes that life was generated originally from nonliving
material, and evolved gradually over billions of years by natural
processes.
Although
evolutionists admit they don’t yet adequately understand how this
happened, that it happened is not negotiable. For them,
evolution is one of the “facts” of scientific life. But should it
be?
Certainly,
you need faith to believe there is a Creator God. But if you believe
that there is no God, you also need faith to believe that.
Was
Darwin right?
Although
the details have changed, the theory of evolution is still essentially
based on the concepts of Charles Darwin (1809-1882). He was not the
first to suggest that life gradually developed in complexity through
evolution, but he did advance a scientific theory to explain how
evolution might have worked.
Darwin’s
ideas have helped shape scientific thinking for more than 100 years.
His original concepts have been reshaped, as Darwin did not fully
grasp the role of genetics. The theory as generally taught today in
the classroom is known as Neo-Darwinism. In essence, Neo-Darwinism is
based on two premises. First, that living organisms are subject to
random variations through mutation. Second, some variations give their
recipients an advantage, so that through natural selection (what came
to be known as ‘“survival of the fittest”), new species develop.
Some
scientists have pointed out that the second of these premises, that
better-adapted life-forms are more likely to survive, is a circular
argument. Obviously, if only the fittest survive, those that survive
are the fittest. This neither proves nor disproves evolution. But what
about the first premise? Can new species develop through random
mutation?
Micro
and macro
Certain
characteristics of living plants and animals change—that cannot be
disputed. Animal breeders have long known how to exploit variation
through artificial selection. Similar variations also occur in nature.
The potential for variation in animals and plants is known as
microevolution, and it explains why we have such variety of life on
earth. Not just generic dogs, cats and horses, but hundreds of
different breeds.
The
theory of evolution suggests that this potential for variation within
species eventually allows one life-form to gradually evolve into
another, into an entirely different species, genus, or family—a
process known as macroevolution.
If
evolution is to work, that is what must happen. But—and this is
crucial to understanding why some scientists see a problem with the
theory—it has never been demonstrated that macroevolution actually
happens! In fact, the evidence seems to point to a different
conclusion.
If
it cannot be shown that macroevolution occurs, a fundamental premise
of evolution is on shaky scientific ground, and to accept this theory
one needs—let’s call it what it is—faith. A paleontologist or
evolutionary biologist might not like that word because of its
religious connotations. But since one definition of faith in Webster’s
Ninth New Collegiate Dictionary is “firm belief in something for
which there is no proof,” then faith it is.
But
faith is not subject to scientific investigation, and this is why the
theory of evolution is being challenged. Not just by creationists, but
by scientists from many branches of science who are committed to
scientific integrity. These scientists believe that because this
fundamental premise of evolution has not been confirmed, the present
conclusions do not adequately explain the origin of new species when
examined by science’s own rules.
Still
missing links
Charles
Darwin recognized some potential flaws in his theory. In particular,
he knew that if evolution progressed slowly across the ages, as he had
suggested, we should expect to find evidence of transitional
life-forms (“missing links”) in the fossil record. The fact that
no such fossils had been found was, Darwin said, “the greatest
objection which can be urged against my theory.”
Darwin
wrote these words in the early days of paleontology, when only a few
fossils had been classified. He was confident that further discoveries
would validate his ideas. But they have not. Today, about 200 million
fossils have been found and classified into about a quarter of a
million species. But in this vast horde, there are still no adequate
fossils that can be considered beyond all doubt transitional forms,
and only a few that are candidates for intermediate forms.
“The
extreme rarity of transitional forms in the fossil record persists as
the trade secret of paleontology,” writes Harvard paleontologist
Stephen Jay Gould in the May 1977 issue of Natural History
(page 14).
A
scientific theory must be based on an objective analysis of the facts.
But so far, the evidence fails to confirm evolution. It points to a
different explanation. Rather than show that life gradually develops
from simple to complex, the fossil record seems to indicate that
life-forms appear abruptly, then they exist with only minor variations
for millions of years, and sometimes abruptly become extinct.
Recognizing
this, some evolutionists have proposed a variation of the Darwinian
model of gradual evolution. Called “Punctuated Equilibria,” it
suggests that since the fossils show that species remain stable for
long periods, then macroevolution must occur suddenly (suddenly, that
is, on a geological time scale, meaning it happened in millions rather
than hundreds of millions of years). This gets around the problem of
missing transitional forms, but it does not resolve the main problem:
There seems to be a “species barrier” beyond which variations do
not happen.
Pig’s
wings and cylindrical eggs
Today,
scientists have confirmed this in ways that Darwin could never have
imagined. We now understand that mutations happen at the level of
genes and chromosomes. But even when examined at the molecular level,
genetic types show resistance to change beyond a certain limit.
Ecologist
Ed Deevey wrote in The Yale Review: “Some remarkable things
have been done by crossbreeding and selection inside the species
barrier, or within the larger circle of closely related species, such
as wheats. But wheat is still wheat, and not, for instance,
grapefruit; and we can no more grow wings on pigs than hens can make
cylindrical eggs” (pages 631-640).
House
of cards
Think
of this built-in potential for variation within a species as a pack of
cards. You can shuffle them, and get many variations of the original
hand. But no amount of shuffling will produce new cards.
Colorful
charts of the development of life and reconstructed fossil
progressions can be rather intimidating to someone who believes in
creation, or in any theory suggesting abrupt appearance. The evidence
for evolution when presented this way seems overwhelming. But such
displays rarely focus on the weaknesses in the underlying theory.
But
if one can’t prove how species evolve, a skillful museum display or
artist’s impression doesn’t mean much. It’s like preparing for a
trip by buying a guidebook and route maps, then discovering your car
doesn’t have an engine!
Scientists
who criticize evolution are not necessarily espousing the
creationist’s cause. Many simply want their colleagues in
paleontology and evolutionary biology to be accurate and objective.
They
recognize that without confirmable data, evolution does not warrant
the distinction of being considered an authoritative theory. If
speculation based on such an unproven premise was advanced in any
other branch of science, it would be considered a highly conjectural
hypothesis, not an idea on which to build a major branch of knowledge.
Other views of the origin and development of life deserve to be heard.
Messy
and personal
But
evolutionists are as human as the rest of us, and it is difficult for
them to admit the role faith plays in their thinking. Notice what
Stephen Jay Gould wrote about what he called the “messy and personal
side of science”: “Our ways of learning about the world are
strongly influenced by the social preconceptions and biased modes of
thinking that each scientist must apply to any problem. The stereotype
of a fully rational and objective ‘scientific method,’ with
individual scientists as logical (and interchangeable robots) is
self-serving mythology” (Natural History, February 1994, page
14).
Unfortunately,
many evolutionists seem to be trapped in circular reasoning: Evolution
must be true; therefore, there must be a mechanism that produces
evolution. And the best candidate is still natural selection from
random mutation. But until this can be demonstrated to occur
naturally, at a macroevolutionary level, it should remain conjecture.
And conclusions based on
it have to be accepted in faith, whether or not evolutionists will
admit it.
A
case for humility

The
Wonders of Creation
An
evolutionist once noted that “if indeed the Creator exists,
he seems to be inordinately fond of beetles,” because he
made so many of them. Our Creator is fond of beetles, and
everything else he has made. He said it was all “very
good” (Genesis 1:31).
God’s
creation is living proof of his absolute mastery of life. He
created life and sustains it, whether on a windswept mountain,
a parched desert or in the deepest ocean abyss. He can make it
beautiful or bizarre, robust or fragile, “larger than
life” or microscopically tiny. But always perfect, intricate
and functional. Through the wonders of creation, God has shown
us he loves life.
God
also loves you and wants you to have life. Not just for a few
short years, but life that lasts forever. God wants you to
have this life so much that “he gave his one and only Son,
that whoever believes in him shall not perish but have eternal
life” (John 3:16).
|
We,
the created, have never been able to make life. Not even a lowly
beetle. But, because of our Creator’s love we are given life that
will last forever. Humbling, isn’t it?
This
should reassure those of us who believe in a divine Creator. It
certainly makes no less sense to believe in a Creator than it does to
believe in evolution. But a note of caution: The failure of evolution
to prove its case does not automatically establish God as Creator to
the skeptic and agnostic. And although the evidence strongly suggests
the abrupt appearance of life, this does not scientifically
establish that such life was divinely created. Some creationists, with
a fundamentalist approach to the Bible, oversimplify the question.
Einstein once said, “Make things as simple as possible, but not more
simple than they are.”
If,
as Stephen Jay Gould says, science has its messy and personal side, so
do some views of the Bible. Some biblical reconstructions of creation
use scriptures and circular reasoning to support preconceived ideas.
Preconceived stereotypes are not the path to understanding.
Evolutionists have not been able to satisfactorily explain the origin
and development of life, but their search has uncovered information
that leads to challenging and exciting questions.
Additionally,
there are many points of view among those who believe in God as
Creator. Scientists with a deep respect for the Bible (and there are
many) recognize that a wealth of information is waiting to be
discovered and interpreted. The search for origins should be an arena
where science and faith meet with mutual respect and tolerance.
“There is bogus or pseudo-science just as much as there is bogus or
pseudo-religion, and the only worthwhile battle is between genuine and
bogus, not between science and religion” (Ken Wilber, Quantum
Questions, New Science Library, 1984, page 21).
