On Darwin's 200th, a theory still in controversy

GREGORY KATZ, Associated Press Writer

LONDON – It's well known that Charles Darwin's

groundbreaking theory of evolution made many people

furious because it contradicted the Biblical view of

creation. But few know that it also created problems for

Darwin at home with his deeply religious wife, Emma.

Darwin held back the book to avoid offending his wife,

said Ruth Padel, the naturalist's great-great-

granddaughter. "She said he seemed to be putting God

further and further off," Padel said in her north London

home. "But they talked it through, and she said, "Don't

change any of your ideas for fear of hurting me.'"

The 1859 publication of "On the Origin of Species"

changed scientific thought forever -- and generated

opposition that continues to this day. It is this elegant

explanation of how species evolve through natural

selection that makes Darwin's 200th birthday on Feb. 12 

such a major event.

More than 300 birthday celebrations are planned in Britain

alone, where Darwin's face graces the 10-pound bill along

with that of Queen Elizabeth II. Shrewsbury, the central

England town where Darwin was born and raised, is

holding a month long festival for its most famous son. And

a permanent exhibition re-creating some of his most

famous experiments is opening at Down House, his

former home near London.

Many more events are planned worldwide, including the

Second World Summit on evolution in the Galapagos

islands in August. In Australia, the Perth Mint is putting out

a special commemorative silver coin.

Even Darwin's ideological adversaries concede that he

was a towering figure.

"He was clearly extremely important, his thinking changed

the world," said Paul Taylor, a spokesman for Answers in

Genesis, a prominent group that rejects Darwin's theory

of evolution in favor of a literal interpretation of the Bible.

"We disagree with his conclusions, with the way he made

extrapolations, but he was a very careful observer and

we've got a lot to be grateful for."

Bob Bloomfield, special projects director at London's

Museum of Natural History, said Darwin was cautious not

only because he didn't want to offend his wife, but also

because he understood that the concept of man's

evolution from other animals was controversial. He didn't

want to present it simply as a hypothesis, but as an

explanation buttressed by many observations and facts.

"He knew he had to make an absolutely iron-cast case for

his theory," Bloomfield said. "He was one of the earliest

true scientists where everything he was prepared to write

about had to be based on evidence."

Darwin's small, handwritten diaries are on display at a

major exhibit at the Museum of Natural History, as well as

thousands of specimens he collected. Some came from

his fabled five-year trip to South America aboard the

Beagle, when he visited the remote Galapagos Islands 

and saw how some species had adapted to its strange,

demanding environment.

The diaries offer insights into Darwin's meticulous,

analytical approach. He even lists the pros and cons of

getting married.

The advantages?

A wife would be a constant companion, a friend in old age,

and fill the house with music and feminine chitchat.

The cons?

Losing the freedom to come and go as he pleased and to

read as much as he wanted at night. Visiting relatives.

And he would have to spend money on children, not

books.

After much deliberation, Darwin renounced the single life:

"One cannot live this solitary life, with groggy old age,

friendless & cold, & childless staring one in ones face,

already beginning to wrinkle," he concluded.

It is in the diaries that Darwin's personality best comes

through, said Padel, one of 72 great-great-grandchildren.

"That's where his real life was," said Padel, an acclaimed

poet. "He had the most amazing sense of wonder. He was

always thinking, 'How does that work?' And that led him to

everything."

Once he married, Darwin turned his family into willing

research assistants. He enlisted his wife to play piano to

a jar of earthworms placed on the piano lid to see if they

would respond to music (they didn't).

Stephen Keynes, a great-grandson, said Darwin also

enlisted his children to throw flour on bees so the path of

their flight could be followed. There are no reports of any

of the children being stung.

"He was the most wonderful father, ever," said Keynes,

81. "He allowed his children access to his study where he

was working at any time."

Darwin was also an innovator at home. He put wheels on

the chair in his study so he could get to his specimens

more quickly -- and, bingo, the modern office chair was

invented.

His passion to understand nature's unseen workings

made him a frequent visitor to the London Zoo, where he

made friends with an orangutan called Jenny. He offered

Jenny a mouth organ and showed her her reflection in the

mirror. He also noted that when her keeper would not give

her an apple, she pouted and sulked like a child. These

seemingly trivial observations helped Darwin develop his

theory that man evolved from primates.

"He was very interested in the expressions of animals and

in particular primates and how similar they could be to

humans," said Becky Coe, an education director at the

zoo, which is setting up a temporary "Darwin Trail" using

animals to help explain evolution. Coe said Darwin went

back to the zoo time and time again to make sure he had

physical evidence for every aspect of his theory.

Darwin's inquisitiveness outlasted his physical vigor.

"Late in life when he was quite ill, he would look at plants

curling up at the window, bending to the light, and he

would wonder, 'How do they do that?'" said Padel. "He

was constantly thinking of relationships and that led him to

understand natural selection. He realized that every

population is in competition with every other. He realized

that is how species adapt, because they are always

competing for light, water and food."

What would he be doing if he were alive today?

Padel thinks he would probably be studying DNA and the

immune system. And she thinks the great scribbler would

be online much of the time.

"He'd be a demon at e-mail," she said.

Associated Press Writer Dean Carson contributed to this

report.

Time To Put Darwin in His Place

Robert Roy Britt, Editorial Director, LiveScience.com

Charles Darwin would be 200 years old this week. And

after all these years, people are still arguing about the

theory of evolution that he fathered.

A primary reason: Some religious groups object to the

notion that humans emerged millions of years ago from

apes, or a common ancestor shared with apes, and that

all life evolved over time, rather than being created as-is

by God. This is the gist of it, though there are numerous

variations on creationist arguments with evolution.

But there's another reason for the ongoing debate that

may surprise you: The terms "Darwinian evolution" and

"Darwinism" - used frequently by scientists, teachers and

the media - are misleading.

Scientists have failed to let Darwin die, even as the

theory he birthed grew up, some scientists now say.

Evolutionary biology has evolved greatly since Darwin

first generated the controversy with the 1859 publication

of On the Origin of Species, and some think it's time to

divorce his name from the theory's name.

The term Darwinism "fails to convey the full panoply of

modern evolutionary biology accurately, and it fosters the

inaccurate perception that the field stagnated for 150

years after Darwin's day," Eugenie C. Scott and Glenn

Branch of the National Center for Science Education

wrote last month in the journal Evolution: Education and

Outreach.

Birth of evolution

In Origin, Darwin proposed that living things descended

with modification from common ancestors. Within a

decade or so, most scientists in Britain, at least, had

accepted this basic idea of evolution, Scott and Branch

explain.

Darwin's other big idea, that evolutionary change was

driven by natural selection, was much slower to catch on,

Scott and Branch write. It took other research, including a

20th-century rediscovery of work by Gregor Mendel - a

priest and contemporary of Darwin who had unraveled the

basic principles of heredity by crossbreeding peas - to

give widespread credence to natural selection.

To scientists nowadays, there is no debate about the

solidity of the theory of evolution. Like the theory of

gravity, evolution has been tested every which way, and

though there remains plenty to learn about some of the

details of how it works, there is no questioning the fact

that it is at work, creating new species such as drug-

resistant bacteria on short time scales or, in the longer

term, humans, who evolved from other primates.

Evolution is one of the most well-established theories in

science, supported by observations in many fields, from

fossil evidence to DNA work done only in recent years.

Other kinds of evolution?

Yet because scientists and the media refer to "Darwinian

evolution," there's an implicit suggestion that there are

other kinds, argues Carl Safina, adjunct professor at

Stony Brook University, in an essay this week in The New

York Times.

"We don't call astronomy Copernicism, nor gravity

Newtonism," Safina points out. "Using phrases like

'Darwinian selection' or 'Darwinian evolution' implies there

must be another kind of evolution at work, a process that

can be described with another adjective. For instance,

'Newtonian physics' distinguishes the mechanical physics

Newton explored from subatomic quantum physics. So

'Darwinian evolution' raises a question: What's the other

evolution?"

There is none, of course.

Scott and Branch, in their paper, delved much deeper into

the confusion fueled by these terms, given that

evolutionary biology has expanded to include many

theories and concepts unknown in the 19th century.

"The term "Darwinism" is, therefore, ambiguous and

misleading," they write.

"Compounding the problem of 'Darwinism' is the hijacking

of the term by creationists to portray evolution as a

dangerous ideology - an 'ism' - that has no place in the

science classroom," Scott and Branch argue. "When

scientists and teachers use 'Darwinism' as synonymous

with evolutionary biology, it reinforces such a misleading

portrayal and hinders efforts to present the scientific

standing of evolution accurately. Accordingly, the term

'Darwinism' should be abandoned as a synonym for

evolutionary biology."

In short, it's time to put Charles Darwin in his place, with

all due respect, and accept that his theory has evolved.
