Monkey Business
The debate over evolution continues
By Jesse Fox Mayshark
JULY 13, 1998:
Andrew Kramer is standing in a room full of skulls. Some of them are
human. The rest...well, that's where it gets tricky. Kramer hefts one in
his hand, a reconstruction of a small domed cranium with a sloping forehead
and deep eye sockets. Its spot on the table is marked with an index card
that says "Homo Habilis." "This, I think, is really one of the key
transitional fossils between a human form and a more apelike form," says
the affable Kramer, an associate professor in the University of Tennessee's
Department of Anthropology. The bone room is two doors over from his
office, along a whitewashed hallway on the ground floor of Neyland Stadium.
Long ago, the rooms were dormitories for UT athletes. The other skulls and
fragments (casts rather than the priceless originals) are spread out over
two tables to form a rough timeline, from 2 million years ago up to modern
Homo Sapiens. Along the way are Homo Erectus, Neanderthal, and several
subgroupings within each species.
For Kramer, the implications of the skulls--with their increasing brain
sizes, rising foreheads, and shrinking brow ridges--is clear. This is human
evolution. "It's difficult to argue the creationist perspective when you
have the whole series of fossil hominids laid out in front of you," he
says. Maybe so. But as Kramer and his colleagues are well aware, the
"creationist perspective" is not so easily discounted.
Seventy-three years after the famous but little-understood Scopes Monkey
Trial in Dayton, Tenn., evolution is still a battlefield. Within the
academy, it is a bedrock principle of several sciences, not much more
controversial than, say, gravity. But in churches, state legislatures, and
schools, the idea that life has mutated and adapted over millions of years,
that humans and apes, dogs, cats, and armadillos all derive from the same
genetic miasma, is at least as contentious as it was in 1925. And the
counterview--Christian "creation science"--has actually become more
anchored to biblical literalism than it was in the days of Scopes. Creation
scientists still don't get much attention outside the realm of evangelical
Christianity; but as the evangelical movement has gathered cultural and
political strength, so have they.
Creationists see evolution as the root of most modern evils. Racism,
war, hedonism--all these arise from the idea that life is a selfish
struggle for survival. Evolutionists, on the other hand, see creationism as
a threat to intellectual liberty, the latest assault in the centuries-old
religious war on free thinking.
At the heart of the creationist platform is the notion that science and
religion should not--cannot--occupy separate realms. Creationists contend
that Christians for too long have been willing to give the material world
to science, reserving only the spirit for God. And they see evolution as
the great wall in this division, one that must be torn down. It's far from
a universal view, of course, even among Christians (not to mention
church-going scientists). But it's one with some resonance.
The 1990s have seen a flurry of legislative efforts around the
country to curb evolution education, including a failed bill two years ago
in Tennessee. At the same time, a small but growing group of dedicated
creationists have begun work on what they hope will be a scrupulously
scientific model that would reconcile the existing data with the biblical
record of creation. So far this year, Tennessee has seen two conferences on
creationism--one in Knoxville and one in Dayton--along with the second
annual pro-evolution Darwin Day symposium at UT.
"This issue rises and falls in the popular press, but it doesn't seem to
go away," says Ronald Numbers, a University of Wisconsin professor of
science history who wrote a 1993 book called The Creationists.
"Although there are some tactical shifts, I don't see any evidence that
would convince me that belief in creation of some kind is going to die out
or is dying down. It's an issue very close to human identity."
Evolution means a lot of different things in different scientific
fields, but it has a few key concepts: Life is dynamic and changes over
time; the major mechanisms for change are mutation and natural selection;
and current living species are descended from earlier, different
species.
In the evolution/creation debate, the first point is usually conceded by
creationists. They don't have any problem with the idea that, for example,
plants or animals can be bred to emphasize certain characteristics or
decrease other ones. But the second one is more prickly--a favorite
creationist line is that no scientist has ever produced an example of a
good mutation (scientists say they do it all the time)--and the third is a
call to arms.
Creationists take a stark view of Darwinism as a system of violence and
struggle, the "survival of the fittest," with no room for morality or
compassion. If God didn't create humans--literally from dust--then humans
aren't responsible to anyone. Evolutionists argue the reverse--that
understanding the complexity of human origin creates more sensitivity
toward the entire natural world.
Listening to a dialogue between the two sides--as at a Monday-evening
debate recently at Knoxville's Civic Auditorium--can be completely
baffling. There is no evidence, no fossil record, to support evolution,
thunders the creationist (in this case, Duane Gish of the California-based
Institute for Creation Research). Sure there is, there's tons of it,
replies the evolutionist (Massimo Pigliucci of UT's botany department,
playing to a crowd largely drawn from area churches). Evolutionists can't
show how invertebrates like trilobites (which look like big marine potato
bugs) turned into fish, the creationist charges. True, there's a lot of
things we can't show, but we will someday, the evolutionist says. And
evolution also violates the Second Law of Thermodynamics, the creationist
says, a "gotcha!" glinting in his eye. No it doesn't, not at all, the
evolutionist calmly rejoins.
Trilobites? The Second Law of Thermodynamics? If anyone in the audience
is swayed by any of this, he doesn't show it. "You can't really just come
into this neutral," asserts Steven Russell, a 14-year-old middle school
student who's there mostly to learn how to bolster his own anti-evolution
arguments. "Everyone in this room has some preconception."
In his UT office the next morning, Pigliucci--who, with his strong
Italian accent, high forehead, and curly hair, could almost be a caricature
of a scientist--admits some of his colleagues think such debates are
pointless or even dangerous, because they give a platform to creationists.
"My response to that is that, first of all, they don't need a platform.
They have it already. They have the attention of the American public," he
says. "If anybody has [something] to gain from getting a platform there,
that's us. Because evolutionary biologists are not heard by the general
public."
The 34-year-old Pigliucci, who received an international award as the
most promising young biologist from the Society for the Teaching of
Evolution last year, never knew evolution was controversial before coming
to the U.S. in 1990. In Europe, he says, there is no evolution/creation
debate.
He became an activist after arriving at UT two years ago; at the time,
the Tennessee Legislature was pondering a bill that would have made it
illegal for teachers to present evolution as "fact" rather than "theory."
The bill failed, not least because state leaders felt it was tarnishing
Tennessee's "New South" image. But it prompted Pigliucci and others at UT
and Oak Ridge to launch the Darwin Day events. If science has a foe, he
says, it's not just creationism; it's ignorance in the public and apathy in
the academy.
"[Scientists] think of this as a scientific debate, and they say, 'That
has been settled a hundred-and-something years ago, what are you wasting
your time for? You should be doing research,' " he says. "What they don't
understand is, if we are not involved in this debate--which is not a
scientific debate, it's an educational debate--we might turn out to not
have any scientific research to do a few years down the road, when
somebody's going to pass a law against funding evolutionary biology at the
federal level."
If that sounds alarmist, Pigliucci notes that he and his colleagues
routinely see the word "evolution" disappear from grant proposals to the
National Science Foundation, the nation's leading supporter of biological
research. In presenting the proposals to Congress, NSF officials often use
euphemisms instead.
Pigliucci--whose desk boasts a statuette of a pixie-winged cherub
flipping its middle finger--is an avowed atheist. But he is not quite so
dismissive of religious objections to evolution as some of his peers. While
many scientists take the soothing middle ground that evolution and religion
can coexist, Pigliucci thinks creationists are right to see a conflict.
"Some particular kinds of gods, some particular kinds of religious
beliefs, are in direct contradiction with science, whether you like it or
not," he says. Among those are most forms of Christian fundamentalism. But
even beyond that, he continues, "I think that if you are intellectually
honest, you have to acknowledge a broader conflict between science and
religion.... Really, there are very few kinds of gods that don't have any
conflict whatsoever with science. "If you believe in miracles of any kind,
then you're denying what science is all about."
Robert Gentry not only believes in miracles--he says he has found
them. A quiet man with steely eyes and a calm but insistent voice, Gentry
has the precise bearing of someone for whom no detail is too small. Giving
directions to his house, he uses phrases like "approximately
point-eight-five miles." The precision got him a position as a visiting
scientist at Oak Ridge National Laboratory for 13 years during the Cold
War. His insistence--in this case, his taciturn belief that the earth is
6,000 years old and the book of Genesis is literally true as written--lost
it for him.
"It's not an easy thing for people to believe, even people who are
interested in believing in the Bible," says Gentry, sitting in the formally
furnished living room of his comfortable home in the Knoxville suburb of
Powell.
A physicist by training, he has spent the last 36 years looking for
clues to the creation and publishing his findings in respected academic
journals, including Science and Nature. His peculiar career
started like those of many other scientists in the 1950s--after receiving a
master's degree from the University of Florida in 1956, he spent several
years working in the defense industry, for military contractors like
General Dynamics. At the time, he was a "theistic evolutionist," a
Christian who accepted the general theory of evolution.
But in 1959, he joined the Seventh-Day Adventist Church, which
emphasizes scriptural literalism. Studying the biblical account of
creationism, Gentry concluded it could not accommodate an evolutionary
approach.
"I sort of wrestled with living with what I felt were two distinct world
views," he says. "I knew that one of them had to be incorrect. So basically
I started an independent research program myself."
He started with radiometric dating, the method by which scientists have
arrived at the generally agreed-upon earth age of about 4.5 billion years.
His research soon led him to the phenomena that have become his specialty,
or maybe more accurately his obsession--pleochroic halos, microscopic
concentric ring patterns formed in some granites by the rapid decay of
radioactive elements. Geologists cannot explain how some of these halos
came to be, given traditional models that say the rocks they're in took
millions of years to form. Gentry--to put his decades of research in simple
terms--thinks they are nothing less than God's fingerprints, impossible
formations put there intentionally as evidence of the spontaneous creation
of the earth. In a self-published book, Creation's Tiny Mystery, he
calls the halos "a Gibraltar of evidence for creation."
Over the years, he has found fellow scientists interested in his
research but scornful of his analysis. While pursuing his doctorate at
Georgia Tech, he was cautioned by the chairman of the physics department to
pursue a "more conventional thesis topic." Instead, Gentry quit the
program. A few years later, his research on "superheavy" elements--a
spin-off of his halo work--brought him to the attention of the U.S. Atomic
Energy Commission and led to the Oak Ridge position. (He was allowed to use
Oak Ridge National Laboratory facilities, but his salary was paid by
Columbia Union College, a Seventh-Day Adventist school in Maryland.)
A turning point came in 1981 when Gentry got a phone call from the
office of the attorney general of Arkansas. The state was preparing to go
to trial defending a law requiring "balanced treatment of creation science
and evolution in public schools." The ACLU was challenging the law; the
state wanted Gentry to come testify in its favor. He knew the trial would
be widely covered by the media.
"I realized there was a good chance my whole position as a guest
scientist at Oak Ridge...that this could easily turn people who had been
very friendly to me to be very negative to me," Gentry says. But feeling it
was "God's providence" for him to present his data, he testified anyway.
When his position came up for renewal at Oak Ridge the next year, it was
terminated. He appealed, with letters of support from U.S. Sen. Jim Sasser
among others, but to no avail.
Since then, Gentry has worked out of his home with limited funding from
various donors. Although his diligence in submitting to and publishing in
academic journals hasn't exactly earned him acceptance, Gentry thinks it's
a reminder to mainstream science that there are other views of the
world.
"Look to the published scientific literature for anything that would
counteract or counterprove what we have said. It isn't there," he
asserts.
Kurt Wise doesn't think much of Robert Gentry's work. In fact, he
doesn't think much of creation science at all, at least not as it's
traditionally been practiced.
"This gets me in a lot of trouble with a lot of creationists," says the
boisterous, bushy-haired professor at Bryan College, a fundamentalist
school founded in Dayton, Tenn., in memory of William Jennings Bryan after
the Scopes trial. "The material that's out there is--uh, I'll hold back and
be nice--garbage. It's really atrocious."
Wise, who's given to manic laughter and arm-flailing when he gets worked
up, is something of a legend in creationist circles. Not yet 40, he's the
great hope of at least some creation scientists (and the bane of many
others). His reputation rests on his unquestionable intellect and
willingness to self-criticize, but even more on his credentials--a master's
degree at the University of Chicago and a doctorate in paleontology from
Harvard University, where he worked under maverick evolutionist and popular
science writer Steven J. Gould.
But if Wise is dismissive of, for example, Gentry (he calls the older
man "sincere" but thinks his halo focus misguided), his own quest has at
least a similar starting point--reconciling the science he loves with the
God he believes in.
He laid out the dilemma in a lecture at an Origins Conference at Bryan
in February: If Christianity arises from the redemption offered by Jesus
Christ, it must also arise from the sin that led to the need for salvation.
Original sin came in the Garden of Eden; Eden came from the creation. If
life actually evolved slowly over millions of years, there was no "first
man" or "first woman." There was also death--of whole species, not to
mention individual organisms--well before there were humans. But the Bible
says death was imposed only after the fall from grace, again setting the
stage for the resurrection promised by Christ.
"If the earth is old, throw out your Bible!" Wise told an audience at
the college's chapel/auditorium.
Wise says he came to that conclusion as a teenager, when he carefully
read the Bible and cut out all the passages that would have to be false if
evolution were true. The result was a tattered text that didn't have enough
paper left to hold together.
But he's also careful not to throw out evolution just because he thinks
it's wrong. It is, he acknowledges, "a very good theory." Simply attacking
it--as Gish mostly did in the Knoxville debate (Gish's name is another that
makes Wise wince)--won't get creationists very far, Wise says.
So he's taking on a more daunting task: putting together an
international team of credentialed scientists to build a comprehensive
creation model in geology, astronomy, biology, and related sciences. One of
their top priorities is looking for evidence of the savage worldwide flood
("40 days and 40 nights") he believes created most modern geology and
topography. This often involves seizing on small bits of scripture ("all
the fountains of the great deep broken up") to theorize about things like
plate tectonics.
"It'll be years before I'm satisfied enough with a model to toss it out
into the scientific community," Wise says. "But I'm working on that."
Creationists are often the only Christian voices heard on the
subject of evolution. But their views are far from universal within the
Christian diaspora. "The Bible is clear that God is the creator, but the
Bible doesn't tell us how," says Bishop Robert Tharp, who heads the East
Tennessee Diocese of the Episcopal Church. "We and the writers of the
gospels don't feel compelled to do it either. We accept God as the creator,
but we also know there are two contrasting creation stories in the first
two chapters of Genesis, and they don't always jibe."
Tharp sees much of the Bible as parable--glimpses of divine workings
that offer more as subjects for meditation than they do as literal history.
He thinks arguments like Wise's miss the broader picture. The point, he
says, is man's obligation to God and to all life.
"When we take it literally, we make God too small. We put Him into our
categories and make Him anthropomorphic, rather than letting God be God,"
he says.
The Catholic Church, 365 years after forcing Galileo to recant his
theories, is also circumspect about creationism. In a statement two years
ago, Pope John Paul II essentially accepted the scientific data of
evolution, claiming only the creation of the soul for God.
"In general, the church certainly believes that there is nothing to be
feared from the truth," says East Tennessee Bishop Anthony O'Connell. "And
secondly, the church has learned over the years that, when it comes to
science, there's no need to run ahead of science."
O'Connell, a former high-school physics and chemistry teacher, says
Catholic schools take a straightforward approach to evolution.
"We certainly don't shy away from the word 'creation,' " he says. "But
we don't present at all the idea that evolution and creation are opposed.
One of the ways creation could have occurred, obviously, is that God
created and then allowed evolution to proceed."
That interpretation is broadly shared by Judaism. Rabbi Howard Simon of
Knoxville's Temple Beth-El says, "What we look for is much more the meaning
that [the creation story] has for us as human beings, rather than the
literalness of the creation. We look at the final result and the
responsibility that is ours."
Tom Ferguson says he can hear minds clicking closed when he uses the
word "evolution." So he avoids it whenever he can.
The veteran educator has taught biology at Knox County's Farragut High
School for 26 years. He and the thousands of other science teachers in the
state are on the front lines of the evolution issue. For a variety of
reasons, they tend to be less strident about it than their colleagues at
the university level.
"The feelings and emotions of high-school students are tender," says
Ferguson, who teaches ninth-grade honors biology. "And of the issues that
you want to bring up in a classroom for the purpose of a heated debate, I
don't think evolution is one to choose."
Not that he doesn't teach evolution--the Prentice Hall textbook for his
class devotes two comprehensive chapters to it--but he introduces it
gently, acknowledging at the forefront that some people have other ideas
about the history of life. He even has creationist books available if
students want to read them. As a result, he says, he rarely hears a
complaint.
But Farragut is a large school with a fairly diverse population.
Evolutionary scientists worry that teachers in more rural, homogeneous
schools are afraid even to bring up evolution. A recent survey of state
science standards by the conservative (but not religious) Fordham
Foundation noted that Tennessee and Mississippi are the only states in the
nation that ignore evolution in their curricula. (The study raised even
more alarms about Alabama's approach: There, every textbook that discusses
evolution has a disclaimer pasted inside the front cover raising doubts
about the subject.)
"I've had a number of teachers tell me they're very cautious," says UT
paleontologist Michael McKinney. "They feel very constrained when they talk
about pressures from the school administration, pressures from the
PTA."
A dedicated environmentalist, McKinney sees a direct link between
anti-evolutionism and issues like overdevelopment and pollution. "I think
it has a lot of practical implications," he says. "Say, here in Tennessee.
I was just screaming about [Gov. Don] Sundquist vetoing the state parks
bill. I mean, this is the most anti-environmental state I've ever been in,
and I think it's not a coincidence that people here aren't all that well
educated on the basics of evolution and biology."
With both evolutionists and creationists feeling embattled, it's no
surprise that neither side expects a resolution.
For Pigliucci, the ongoing insistence on creation merely descends from
ancient beliefs that everything from sunrise to lightning was a divine act.
Evolutionists call it "the god of the gaps"--inserting God wherever science
falls short. It's a process Pigliucci expects will continue.
"Everybody is interested in the fundamental questions of life. Everybody
wants to know, where do we come from and what are we here for," he says.
"And then there is the easy answer and there is the complex answer. There's
the answer that requires no homework, and there's the answer that requires
lifelong homework."
Wise already knows the answers. When he was a precocious 9-year-old, he
came to the conclusion that there was no way to prove that the universe or
even he himself actually existed. Shortly before Easter, he decided he
would kill himself the next week. But at church that weekend, his Sunday
school teacher directed him to Romans 5:8--"But God commended his love
toward us in that while we are yet sinners, Christ died for us." It changed
the young boy's life. And it's that faith that drives his research.
"This is truth," he says. "God created the universe, and the earth, and
the seas.... He did that. My fun job, my vocation, is to understand the
creation in the light of that. Not to prove it--it doesn't need any proof.
Because it's true."
