Texas Board of Education will try to reverse evolution

The Texas Board of Education, commanding control over one of the largest textbook markets in the country, may change science curriculum for Texas public schools to reflect a non-scientific point of view that the natural world did not come about naturally but rather through the intervention of supernatural beings (i.e., the Christian god).

This from the Wall Street Journal:
The Texas Board of Education will vote this week on a new science curriculum designed to challenge the guiding principle of evolution, a step that could influence what is taught in biology classes across the nation.

The proposed curriculum change would prompt teachers to raise doubts that all life on Earth is descended from common ancestry. Texas is such a huge textbook market that many publishers write to the state's standards, then market those books nationwide.

"This is the most specific assault I've seen against evolution and modern science," said Steven Newton, a project director at the National Center for Science Education, which promotes teaching of evolution.

Texas school board chairman Don McLeroy also sees the curriculum as a landmark -- but a positive one.

Rev. Carl W. Rohlfs of the University United Methodist Church in Austin, left, talks with Texas Freedom Network President Kathy Miller, right, Thursday in Austin. The State Board of Education is voting on science-curriculum standards on the teaching of evolution.

Dr. McLeroy believes that God created the earth less than 10,000 years ago. If the new curriculum passes, he says he will insist that high-school biology textbooks point out specific aspects of the fossil record that, in his view, undermine the theory that all life on Earth is descended from primitive scraps of genetic material that first emerged in the primordial muck about 3.9 billion years ago.

He also wants the texts to make the case that individual cells are far too complex to have evolved by chance mutation and natural selection, an argument popular with those who believe an intelligent designer created the universe.

The textbooks will "have to say that there's a problem with evolution -- because there is," said Dr. McLeroy, a dentist. "We need to be honest with the kids."

The vast majority of scientists accept evolution as the best explanation for the diversity of life on earth.

Yes, they say, there are unanswered questions -- transitional fossils yet to be unearthed, biological processes still to be discovered. There is lively scientific debate about some aspects of evolution's winding, four-billion-year path. But when critics talk about exposing students to the "weaknesses" or "insufficiencies" in evolutionary theory, many mainstream scientists cringe.

The fossil record clearly supports evolution, they say, and students shouldn't be exposed to creationist critiques in the name of "critical thinking."

"We will be teaching nonsense in the science classroom," said David Hillis, a biology professor at the University of Texas at Austin.

Polls show many Americans are skeptical of or confused by evolution; in a recent survey by Gallup, 39% said they believe the theory, 25% said they didn't, and 36% had no opinion.

The Discovery Institute, a Seattle think tank that challenges evolution, cites a recent Zogby poll that found a strong majority of Americans supports letting teachers explore both "strengths and weaknesses" of evolution. Otherwise, students see only "cherry-picked evidence that really amounts to propaganda," said John West, a senior fellow at the Discovery Institute.

The Texas school board will vote after taking public testimony in a three-day meeting that starts Wednesday. Dr. McLeroy leads a group of seven social conservatives on the 15-member board. They are opposed by a bipartisan group of seven, often joined by an eighth board member considered a swing vote, that support teaching evolution without caveats.

Neither side is confident of victory. All members of the board have come under enormous pressure in recent months, especially three Republicans who support teaching evolution without references to "weaknesses." The state Republican Party passed a resolution urging the three to back Dr. McLeroy's preferred curriculum. A conservative activist group put out a news release suggesting all three were in the pocket of "militant Darwinists."
Of course, any pretense that this proposal is done for the purpose of promoting critical thinking is absurd. One can only imagine the reaction of the very same anti-evolution proponents to a religion course exposing students to the "weaknesses" or "insufficiencies" in Christianity.

But back to the more important point and that is the public is confused about what evolution really is. One of the fundamentals of any debate is to “define your terms” and that is essential. Edward Hume had these thoughts on that subject a couple of years ago:
… There are really two theories of evolution. There is the genuine scientific theory, and there is the talk-radio pretend version, designed not to enlighten but to deceive and enrage.

The talk-radio version had a packed town hall up in arms at the "Why Evolution Is Stupid" lecture. In this version of the theory, scientists supposedly believe that all life is accidental, a random crash of molecules that magically produced flowers, horses and humans — a scenario as unlikely as a tornado in a junkyard assembling a 747. Humans come from monkeys in this theory, just popping into existence one day. The evidence against Darwin is overwhelming, the purveyors of talk-radio evolution rail, yet scientists embrace his ideas because they want to promote atheism.

These are just a few highlights of the awful and pervasive straw-man image of evolution that pundits harp about in books and editorials and, yes, on talk radio, and this cartoon version really is stupid. No wonder most Americans reject evolution in poll after poll.

But then there is the real theory of evolution, … for which there is overwhelming evidence in labs, fossils, computer simulations and DNA studies. Most Americans have not heard of it. Teachers give it short shrift in schools because the subject upsets too many parents who only know the talk-radio version. But real evolution isn't random; it doesn't say man came from monkeys. Those claims are made up by critics to get people riled up — paving the way for pleasing alternatives like intelligent design.

Real evolutionary theory explains how life forms change across generations by passing on helpful traits to their offspring; a process that, after millions of years, gradually transforms one species into another. This does not happen randomly but through nature's tendency to reward the most successful organisms and to kill the rest. This is why germs grow resistant to antibiotics and why some turtles are sea animals and others survive quite nicely in the desert, and why dinosaurs — and more than 99% of all other species that have ever lived on Earth — are extinct.

The environment changes. The recipe for survival changes with it. And life changes to keep up — or it dies. Darwin's signature insight is both brilliant and elegantly, brutally simple.

The real theory of evolution does not try to explain how life originated — that remains a mystery…

When I was in high school, evolution was taught in my biology class, but the textbook contained a disclaimer sticker signifying that evolution was just a "theory" and should be taken as such.
