About Becky Jungbauer

A scientist and journalist by training, I enjoy all things science, especially science-related humor. My column title is a throwback to Jane Austen's famous first line in Pride and Prejudice


... Full Bio

The Texas Board of Education is voting this week on a new science curriculum designed to challenge the guiding principle of evolution, according to the Wall Street Journal.

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.

I briefly mentioned this issue at the end of a post back in January, at which point the Board was divided about the curriculum content. But the future of our children's scientific knowledge seems pretty precarious, given that the Board chairman, a dentist named Don McLeroy, believes that God created the earth less than 10,000 years ago, and wants textbooks "to be honest with kids" that there is a "problem" with evolution.

According to Dr. McLeroy, specific aspects of the fossil record undermine the theory that all life on earth is descended from primitive scraps of genetic material. And individual cells are "far too complex" to have evolved by chance mutation and natural selection.

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."

Militant Darwinists have pockets?    Seriously, they think there is a well-funded Big Darwin cabal?  A secret society of rich atheists trying to ruin our children by teaching science?

I'm a lot more forgiving than most here about quirky cultural reservoirs; I like Texas, and Texans, because this is the kind of stuff they like to do; it's still important that they fail here.

Eugenie Scott runs the National Center for Science Education so she is always on the forefront of this.   They're also a good place to go to counteract some of the crazier arguments in use.

What's so frustrating about this issue is that people like McLeroy are pushing incoherent criticisms. They are hopelessly confused.  They conflate prebiotic evolution (the origins of the first cells), natural selection, and common ancestry. All of those points are independent.
We don't know how the first cells arose, but this subject is not really part the high school biology curriculum, nor is it essential for understanding common ancestry and natural selection. As Darwin pointed out, a designer could have poofed the first cells into existence, and then all subsequent life could have descended from the original populations of cells.

Common ancestry is also an independent concept - it doesn't depend on the truth of natural selection (and in fact Darwin's early scientific critics accepted common ancestry but doubted natural selection). It's also one of the most thoroughly verified ideas in evolutionary biology - there is absolutely NO way to explain the similarities and differences in DNA among living organisms except by common ancestry, or by invoking a designer who made things look as if they descended from common ancestors. Even without any fossils, the DNA evidence would establish common ancestry beyond any doubt.

Finally, natural selection could have occurred even without the common ancestry of all life - even many creationists accepts so-called microevolution (of say, Darwin's finches), which is produced by natural selection. Natural selection can be directly observed in the wild, so it's absurd to try to eliminate this from the curriculum.

But McLeroy is confused - he seems to think that if he can debunk a non-magical explanation for the origins of the first cells, then natural selection and common ancestry also fall. The guy is a raving lunatic, and it's crazy that such a person can be in a position of power over the education of our kids.
