Biology textbook hearings prompt science disputes [Texas]

FORT WORTH, Texas - (KRT) -
The long-running debate over the origins of mankind continues Wednesday before the Texas State Board of Education, and the result could change the way science is taught here and across the nation.

Local and out-of-state lobbying groups will try to convince the board that the next generation of biology books should contain new scientific evidence that reportedly pokes holes in Charles Darwin's theory of evolution.

Many of those groups say that they are not pushing to place a divine creator back into science books, but to show that Darwin's theory is far from a perfect explanation of the origin of mankind.

"It has become a battle ground," said Eugenie Scott, executive director of theNational Center of Science Education, which is dedicated to defending the teaching of evolution in the classroom.

Almost 45 scientists, educators and special interest groups from across the state will testify at the state's first public hearing this year on the next generation of textbooks for the courses of biology, family and career studies and English as a Second Language.

Approved textbooks will be available for classrooms for the 2004-05 school year. And because Texas is the second largest textbook buyer in the nation, the outcome could affect education nationwide.

The Texas Freedom Network and a handful of educators held a conference call last week to warn that conservative Christians and special interest organizations will try to twist textbook content to further their own views.

"We are seeing the wave of the future of religious right's attack on basic scientific principles," said Samantha Smoot, executive director of the network, an anti-censorship group and opponent of the radical right.

Those named by the network disagree with the claim, including the Discovery Institute and its Science and Culture Center of Seattle.

"Instead of wasting time looking at motivations, we wish people would look at the facts," said John West, associate director of the center.

"Our goal nationally is to encourage schools and educators to include more about evolution, including controversies about various parts of Darwinian theory that exists between even evolutionary scientists," West said. "We are a secular think tank."

The institute also is perhaps the nation's leading proponent of intelligent design - the idea that life is too complex to have occurred without the help of an unknown, intelligent being.

It pushed this view through grants to teachers and scientists, including Michael J. Behe, professor of biological sciences at Lehigh University in Pennsylvania. The Institute receives millions of dollars from philanthropists and foundations dedicated to discrediting Darwin's theory.

The center sent the state board a 55-page report that graded 11 high school biology textbooks submitted for adoption. None earned a grade above a C minus. The report also includes four arguments it says show that evolutionary theory is not as solid as presented in biology textbooks.

Discovery Institute Fellow Raymond Bohlin, who also is executive director of Probe Ministries, based in Richardson, Texas, will deliver that message in person Wednesday before the State Board of Education. Bohlin has a doctorate degree in molecular cell biology from the University of Texas at Dallas.

"If we can simply allow students to see that evolution is not an established fact, that leaves freedom for students to pursue other ideas," Bohlin said. "All I can do is continue to point these things out and hopefully get a group that hears and sees relevant data and insist on some changes."

The executive director of Texas Citizens for Science, Steven Schafersman, calls the institute's information "pseudoscience nonsense." Schafersman is an evolutionary scientist who, for more than two decades, taught biology, geology, paleontology and environmental science at a number of universities, including the University of Houston and the University of Texas of the Permian Basin.

"It sounds plausible to people who are not scientifically informed," Schafersman said. "But they are fraudulently trying to deceive board members. They might succeed, but it will be over the public protests of scientists."

The last time Texas looked at biology books, in 1997, the State Board of Education considered replacing them all with new ones that did not mention evolution. The board voted down the proposal by a slim margin.

The state requires that evolution be in textbooks. But arguments against evolution have been successful over the last decade in other states. Alabama, New Mexico and Nebraska made changes that, to varying degrees, challenge the pre-eminence of evolution in the scientific curriculum.

In 1999, the Kansas Board of Education voted to wash the concepts of evolution from the state's science curricula. A new state board has since put evolution back in. Last year, the Cobb County school board in Georgia voted to include creationism in science classes.

Texas education requirements demand that textbooks include arguments for and against evolution, said Neal Frey, an analyst working with perhaps Texas' most famous textbook reviewers, Mel and Norma Gabler.

The Gablers, of Longview, have been reviewing Texas textbooks for almost four decades. They describe themselves as conservative Christians. Some of their priorities include making sure textbooks include scientific flaws in arguments for evolution.

"None of the texts truly conform to the state's requirements that the strengths and weaknesses of scientific theories be presented to students," Frey said.

The Texas textbook proclamation of 2001, which is part of the standard for the state's curriculum, Texas Essential Knowledge and Skills, requires that biology textbooks instruct students so they may "analyze, review and critique scientific explanations, including hypotheses and theories, as to their strengths and weakness using scientific evidence and information."

The state board is empowered to reject books only for factual errors or for not meeting the state's curriculum requirements. If speakers convince the state board that their evidence is scientifically sound, members may see little choice but to demand its presence in schoolbooks.

Proposed books already have been reviewed and approved by Texas Tech University. After a public hearing Wednesday and another Sept. 10, the state board is scheduled to adopt the new textbooks in November.

Satisfying the state board is only half the battle for textbook publishers. Individual school districts choose which books to use and are reimbursed by the state unless they buy texts rejected by the state board.

Districts can opt not to use books with passages they find objectionable. So when speakers at the public hearings criticize what they perceived as flaws in various books - such as failing to portray the United States or Christianity in a positive light - many publishers listen.

State Board member Terri Leo said the Discovery Institute works with esteemed scientists and that their evidence should be heard.

"You cannot teach students how to think if you don't present both sides of a scientific issue," Leo said. "Wouldn't you think that the body that has the responsibility of what's in the classroom would look at all scientific arguments?"

State board member Bob Craig said he had heard of the Intelligent Design theory.

"I'm going in with an open mind about everybody's presentation," Craig said. "I need to hear their presentation before I make any decisions or comments.

State board member Mary Helen Berlanga said she wanted to hear from local scientists.

"If we are going to discuss scientific information in the textbooks, the discussion will have to remain scientific," Berlanga said. "I'd like to hear from some of our scientists in the field on the subject."

Seems I recall asking a few hundred posts back for an example of ONE (1) experiment in the Origins and receiving no response - as usual.

Pigeons

Believing that it is always best to study some special group, I have, after deliberation, taken up domestic pigeons. I have kept every breed which I could purchase or obtain, and have been most kindly favoured with skins from several quarters of the world, more especially by the Hon. W. Elliot from India, and by the Hon. C. Murray from Persia. Many treatises in different languages have been published on pigeons, and some of them are very important, as being of considerable antiquity. I have associated with several eminent fanciers, and have been permitted to join two of the London Pigeon Clubs....
In the skeletons of the several breeds, the development of the bones of the face, in length and breadth and curvature, differs enormously. The shape, as well as the breadth and length of the ramus of the lower jaw, varies in a highly remarkable manner. The caudal and sacral vertebrae vary in number; as does the number of the ribs, together with their relative breadth and the presence of processes. The size and shape of the apertures in the sternum are highly variable; so is the degree of divergence and relative size of the two arms of the furcula. The proportional width of the gape of mouth, the proportional length of the eyelids, of the orifice of the nostrils, of the tongue...
[Darwin goes on at some length. MANY OF THESE ARE ORIGINAL OBSERVATIONS, or ones that Darwin confirmed independently. (Yes, systematic and compartive observations are experiments.) Desmond & Moore's biography, Darwin, describes Darwin's extensive anatomical experiments on page 427. Darwin came to love his pidgeons, however, and the necessity of killing and skeletonizing them in large numbers (all the different breeds and at all stages of development), and probably complaints from the family about the ghoulish mess and the stench of boiling pidgeon, lead him to eventually have the skeletons created professionally. Of course he did soft tissue dissection himself. Back to The Origin where Darwin's breeding experiments are described, although with only a bare hint of their prodigious extent:]
Great as are the differences between the breeds of the pigeon, I am fully convinced that the common opinion of naturalists is correct, namely, that all are descended from the rock-pigeon (Columba livia), including under this term several geographical races or sub-species, which differ from each other in the most trifling respects...
Some facts in regard to the colouring of pigeons well deserve consideration. The rock-pigeon is of a slaty-blue, with white loins; but the Indian sub-species, C. intermedia... [much deleted about coloration in pidgeons] To give one instance out of several which I have observed: I crossed some white fantails, which breed very true, with some black barbs-- and it so happens that blue varieties of barbs are so rare that I never heard of an instance in England; and the mongrels were black, brown and mottled. I also crossed a barb with a spot, which is a white bird with a red tail and red spot on the forehead, and which notoriously breeds very true; the mongrels were dusky and mottled. I then crossed one of the mongrel barb-fantails with a mongrel barb-spot, and they produced a bird of as beautiful a blue colour, with the white loins, double black wing-bar, and barred and white-edged tail-feathers, as any wild rock-pigeon! We can understand these facts, on the well-known principle of reversion to ancestral characters, if all the domestic breeds are descended from the rock-pigeon. But if we deny this, we must make one of the two following highly improbable suppositions. Either, first, that all the several imagined aboriginal stocks were coloured and marked like the rock-pigeon, although no other existing species is thus coloured and marked, so that in each separate breed there might be a tendency to revert to the very same colours and markings. Or, secondly, that each breed, even the purest, has within a dozen, or at most within a score, of generations, been crossed by the rock-pigeon: I say within a dozen or twenty generations, for no instance is known of crossed descendants reverting to an ancestor of foreign blood, removed by a greater number of generations...
Lastly, the hybrids or mongrels from between all the breeds of the pigeon are perfectly fertile, as I can state from my own observations, purposely made, on the most distinct breeds.

So there's ONE (1) experiment -- actually a whole body of experiment, hundreds or thousands of individual ones -- conducted in great detail and over years by Darwin himself in both anatomically comparing and breeding pidgeons. There is much more. Maybe one or two more examples, related more briefly:

Orchids & other plants

I am tempted to give one more instance showing how plants and animals, remote in the scale of nature, are bound together by a web of complex relations. I shall hereafter have occasion to show that the exotic Lobelia fulgens is never visited in my garden by insects, and consequently, from its peculiar structure, never sets a seed. Nearly all our orchidaceous plants absolutely require the visits of insects to remove their pollen-masses and thus to fertilise them. I find from experiments that humble-bees are almost indispensable to the fertilisation of the heartsease (Viola tricolor), for other bees do not visit this flower. I have also found that the visits of bees are necessary for the fertilisation of some kinds of clover; for instance twenty heads of Dutch clover (Trifolium repens) yielded 2,290 seeds, but twenty other heads, protected from bees, produced not one. Again, 100 heads of red clover (T. pratense) produced 2,700 seeds, but the same number of protected heads produced not a single seed. Humble bees alone visit red clover, as other bees cannot reach the nectar...

Well, that's enough, but again, there is MUCH more, even confining ourselves only to experiments conducted by Darwin himself. For instance search for "CELL-MAKING INSTINCT OF THE HIVE-BEE". It's much to long to quote, even in abbreviation, but Darwin describes a number of experiments he conducted by giving bees blocks of wax with different properties to work on, or interrupting cell construction at different points, and various other manipulations.

In dicussing the distribution and migration of species (as, for instance, in the population of islands) Darwin alludes to his extensive experiments soaking seeds in saltwater for various periods and then attempting their germination, and a whole host of similar investigations.

I hope this is sufficient for you gore (he said, knowing it won't be, and that nothing ever could be).
