Now evolving in biology classes: a testier climate
Some science teachers say they're encountering fresh resistance to the topic
of evolution - and it's coming from their students.
By G. Jeffrey MacDonald | Correspondent of The Christian Science Monitor
Nearly 30 years of teaching evolution in Kansas has taught Brad Williamson to
expect resistance, but even this veteran of the trenches now has his work cut
out for him when students raise their hands.
That's because critics of Charles Darwin's theory of natural selection are
equipping families with books, DVDs, and a list of "10 questions to ask your
biology teacher."
The intent is to plant seeds of doubt in the minds of students as to the
veracity of Darwin's theory of evolution.
The result is a climate that makes biology class tougher to teach. Some
teachers say class time is now wasted on questions that are not science-based.
Others say the increasingly charged atmosphere has simply forced them to work
harder to find ways to skirt controversy.
On Thursday, the Science Hearings Committee of the Kansas State Board of
Education begins hearings to reopen questions on the teaching of evolution in
state schools.
The Kansas board has a famously zigzag record with respect to evolution. In
1999, it acted to remove most references to evolution from the state's science
standards. The next year, a new - and less conservative - board reaffirmed
evolution as a key concept that Kansas students must learn.
Now, however, conservatives are in the majority on the board again and have
raised the question of whether science classes in Kansas schools need to
include more information about alternatives to Darwin's theory.
But those alternatives, some science teachers report, are already making
their way into the classroom - by way of their students.
In a certain sense, stiff resistance on the part of some US students to the
theory of evolution should come as no surprise.
Even after decades of debate, Americans remain deeply ambivalent about the
notion that the theory of natural selection can explain creation and its genesis.
A Gallup poll late last year showed that only 28 percent of Americans accept
the theory of evolution, while 48 percent adhere to creationism - the belief
that an intelligent being is responsible for the creation of the earth and its
inhabitants.
But if reluctance to accept evolution is not new, the ways in which students
are resisting its teachings are changing.
"The argument was always in the past the monkey-ancestor deal," says Mr.
Williamson, who teaches at Olathe East High School. "Today there are many more
arguments that kids bring to class, a whole fleet of arguments, and they're all
drawn out of the efforts by different groups, like the intelligent design
[proponents]."
It creates an uncomfortable atmosphere in the classroom, Williamson says -
one that he doesn't like. "I don't want to ever be in a confrontational mode
with those kids ... I find it disheartening as a teacher."
Williamson and his Kansas colleagues aren't alone. An informal survey
released in April from the National Science Teachers Association found that 31
percent of the 1,050 respondents said they feel pressure to include "creationism,
intelligent design, or other nonscientific alternatives to evolution in their
science classroom."
These findings confirm the experience of Gerry Wheeler, the group's executive
director, who says that about half the teachers he talks to tell him they
feel ideological pressure when they teach evolution.
And according to the survey, while 20 percent of the teachers say the
pressure comes from parents, 22 percent say it comes primarily from students.
In this climate, science teachers say they must find new methods to defuse
what has become a politically and emotionally charged atmosphere in the
classroom. But in some cases doing so also means learning to handle well-organized
efforts to raise doubts about Darwin's theory.
Darwin's detractors say their goal is more science, not less, in evolution
discussions.
The Seattle-based Discovery Institute distributes a DVD, "Icons of
Evolution," that encourages viewers to doubt Darwinian theory.
One example from related promotional literature: "Why don't textbooks discuss
the 'Cambrian explosion,' in which all major animal groups appear together in
the fossil record fully formed instead of branching from a common ancestor -
thus contradicting the evolutionary tree of life?"
Such questions too often get routinely dismissed from the classroom, says
senior fellow John West, adding that teachers who advance such questions can be
rebuked - or worse.
"Teachers should not be pressured or intimidated," says Mr. West, "but what
about all the teachers who are being intimidated and in some cases losing their
jobs because they simply want to present a few scientific criticisms of
Darwin's theory?"
But Mr. Wheeler says the criticisms West raises lack empirical evidence and
don't belong in the science classroom.
"The questions scientists are wrestling with are not the same ones these
people are claiming to be wrestling with," Wheeler says. "It's an effort to
sabotage quality science education. There is a well-funded effort to get religion
into the science classroom [through strategic questioning], and that's not fair
to our students."
A troubled history
Teaching that humans evolved by a process of natural selection has long
stirred passionate debate, captured most famously in the Tennessee v. John Scopes
trial of 1925.
Today, even as Kansas braces for another review of the question, parents in
Dover, Pa., are suing their local school board for requiring last year that
evolution be taught alongside the theory that humankind owes its origins to an
"intelligent designer."
In this charged atmosphere, teachers who have experienced pressure are
sometimes hesitant to discuss it for fear of stirring a local hornets' nest. One
Oklahoma teacher, for instance, canceled his plans to be interviewed for this
story, saying, "The school would like to avoid any media, good or bad, on such an
emotionally charged subject."
Others believe they've learned how to successfully navigate units on
evolution.
In the mountain town of Bancroft, Idaho (pop. 460), Ralph Peterson teaches
all the science classes at North Gem High School. Most of his students are
Mormons, as is he.
When teaching evolution at school, he says, he sticks to a clear but simple
divide between religion and science. "I teach the limits of science," Mr.
Peterson says. "Science does not discuss the existence of God because that's
outside the realm of science." He says he gets virtually no resistance from his
students when he approaches the topic this way.
In Skokie, Ill., Lisa Nimz faces a more religiously diverse classroom and a
different kind of challenge. A teaching colleague, whom she respects and
doesn't want to offend, is an evolution critic and is often in her classroom when
the subject is taught.
In deference to her colleague's beliefs, she says she now introduces the
topic of evolution with a disclaimer.
"I preface it with this idea, that I am not a spiritual provider and would
never try to be," Ms. Nimz says. "And so I am trying not ... to feel any
disrespect for their religion. And I think she feels that she can live with that."
A job that gets harder
The path has been a rougher one for John Wachholz, a biology teacher at
Salina (Kansas) High School Central. When evolution comes up, students tune out:
"They'll put their heads on their desks and pretend they don't hear a word you
say."
To show he's not an enemy of faith, he sometimes tells them he's a choir
member and the son of a Lutheran pastor. But resistance is nevertheless getting
stronger as he prepares to retire this spring.
"I see the same thing I saw five years ago, except now students think they're
informed without having ever really read anything" on evolution or
intelligent design, Mr. Wachholz says. "Because it's been discussed in the home and
other places, they think they know, [and] they're more outspoken.... They'll say,
'I don't believe a word you're saying.' "
As teachers struggle to fend off strategic questions - which some believe are
intended to cloak evolution in a cloud of doubt - critics of Darwin's theory
sense an irony of history. In their view, those who once championed teacher
John Scopes's right to question religious dogma are now unwilling to let a new
set of established ideas be challenged.
"What you have is the Scopes trial turned on its head because you have school
boards saying you can't say anything critical about Darwin," says Discovery
Institute president Bruce Chapman on the "Icons of Evolution" DVD.
But to many teachers, "teaching the controversy" means letting ideologues
manufacture controversy where there is none. And that, they say, could set a
disastrous precedent in education.
"In some ways I think civilization is at stake because it's about how we view
our world," Nimz says. The Salem Witch Trials of 1692, for example, were
possible, she says, because evidence wasn't necessary to guide a course of action.
"When there's no empirical evidence, some very serious things can happen,"
she says. "If we can't look around at what is really there and try to put
something logical and intelligent together from that without our fears getting in
the way, then I think that we're doomed."

What some students are asking their biology teachers
Critics of evolution are supplying students with prepared questions on such
topics as:
• The origins of life. Why do textbooks claim that the 1953 Miller-Urey
experiment shows how life's building blocks may have formed on Earth - when
conditions on the early Earth were probably nothing like those used in the
experiment, and the origin of life remains a mystery?
• Darwin's tree of life. Why don't textbooks discuss the "Cambrian
explosion," in which all major animal groups appear together in the fossil record fully
formed instead of branching from a common ancestor - thus contradicting the
evolutionary tree of life?
• Vertebrate embryos. Why do textbooks use drawings of similarities in
vertebrate embryos as evidence for common ancestry - even though biologists have
known for over a century that vertebrate embryos are not most similar in their
early stages, and the drawings are faked?
• The archaeopteryx. Why do textbooks portray this fossil as the missing link
between dinosaurs and modern birds - even though modern birds are probably
not descended from it, and its supposed ancestors do not appear until millions
of years after it?
• Peppered moths. Why do textbooks use pictures of peppered moths camouflaged
on tree trunks as evidence for natural selection - when biologists have known
since the 1980s that the moths don't normally rest on tree trunks, and all
the pictures have been staged?
• Darwin's finches. Why do textbooks claim that beak changes in Galapagos
finches during a severe drought can explain the origin of species by natural
selection - even though the changes were reversed after the drought ended, and no
net evolution occurred?
• Mutant fruit flies. Why do textbooks use fruit flies with an extra pair of
wings as evidence that DNA mutations can supply raw materials for evolution -
even though the extra wings have no muscles and these disabled mutants cannot
survive outside the laboratory?
• Human origins. Why are artists' drawings of apelike humans used to justify
materialistic claims that we are just animals and our existence is a mere
accident - when fossil experts cannot even agree on who our supposed ancestors
were or what they looked like?
• Evolution as a fact. Why are students told that Darwin's theory of
evolution is a scientific fact - even though many of its claims are based on
misrepresentations of the facts?
