Evolutionary biologists study fossils to trace the origins of species. In addition to asking teachers to engage Texas students in a discussion of how gaps in the fossil record might undermine the notion of common ancestry, McLeroy says he will ask board members to adopt a curriculum standard that would ask students to explain how the complexity of cells does or does not support the idea of natural selection, an explanation of how organisms evolve.

The board is expected to make a final decision on the science curriculum March 27.

University of Texas professor David Hillis helped form a group called the 21st Century Science Coalition to combat the effort to include the weaknesses of evolution in the public school curriculum.

"If Chairman McLeroy is successful in adding his amendments, it will be a huge embarrassment to Texas, a setback for science education and a terrible precedent for the state boards overriding academic experts in order to further their personal religious or political agendas. The victims will be the schoolchildren of Texas, who represent the future of our state."
More than 600 Texas science faculty members have signed a petition supporting the group'seffort.

One by one, he said, his questions were answered by pastors and in Bible studies. The conversion took four months. Over the next year, he began taking seminars on creationism and biblical principles. He is now a young earth creationist, meaning that he believes God created Earth between 6,000 and 10,000 years ago.
The tenet in Christianity that says people were created in the image of God became one of the principles that McLeroy held most dear, he said.
"When I became a Christian, it was whole-hearted," he said. "I was totally convinced the biblical principles were right, and I was totally convinced that it could be accurate scientifically."

Sid Hall, pastor of Trinity United Methodist Church in Austin, which recently celebrated the 200th anniversary of naturalist Charles Darwin's birth with an "evolution Sunday" event, said he finds this kind of mixing of science and religion disturbing. Hall said that it is disingenuous to attack the fossil record and ignore carbon dating and dangerous to adhere to only the most literal interpretations of the Bible.
"I would never want to discount those works, but to take (the passage that humans were made in the image of God) to mean something about how the universe is created is a stretch to me," Hall said. "That's code to me for 'I'm going to take my particular myth of creationism and make it part of the science curriculum.' That's scary to me."

While recovering from prostate cancer last year, McLeroy said, he studied what Miller and others have written on the topic. His research led him to what he believes are scientific weaknesses that he wants to see included in the state's curriculum standards.
"If you want children to become good scientists, to become excited about that, you've got to be honest with them. And to be honest with them, you've got to show them the data," he said.
McLeroy, who was elected with about 59 percent of the vote in 2006, said he has numerous letters from constituents encouraging his efforts.

In January, the board voted 8-7 to reject a requirement that students be taught the weaknesses of evolution. However, McLeroy was able to get some amendments passed.
"He waited until all 14 members spoke and then handed the gavel off ... and said, 'Look, I've got an opinion.' He was really careful to try and shepherd the process without bias, and I think that's a real strength," said Bradley, who voted with McLeroy.
McLeroy's amendments included adding a requirement that students analyze and evaluate the insufficiencies of the theory of common ancestry to explain gaps in the fossil record.
He has succeeded in rewriting the state's definition of science as it pertains to teaching to require "testable explanations" of nature. McLeroy said the change should allow the questioning of all scientific explanations and opens the door to the possibility that the universe was created by God. But he wants more.
McLeroy says he intends to pitch another idea that he says should be taught in public schools: the insufficiency of natural selection to explain the complexity of cells.

Hillis said the language that McLeroy has proposed to add to the standards does not make sense.
"The language of science needs to be precise; McLeroy's amendments are not even intelligible. I wonder if perhaps he wants the standards to be confusing so that he can open the door to attacking mainstream biology textbooks and arguing for the addition of creationist and other religious literature into the science classroom," Hillis said.
Miller said, "The attitude (that evolution has weaknesses) does Texas a disservice on two levels. The first thing is it implies a false sense of uncertainty on evolution ... and the reality is exactly the opposite. Evolution is very solid and increasingly accepted.
"The second point is even more dangerous," Miller said. "It implies a false sense of certainty about everything else in biology. ... I think it presents a really distorted view of the biological sciences to tell students that 'we're pretty sure of everything else in biology, but evolutionary theory, kids, is a little shaky.' "
