It looks like we have narrowly averted a major assault against science education in Texas, but that Champion of Ignorance, Dr. McLeroy continue the assault with what has been termed a death of a thousand cuts. One of his wedge arguments he tried to get in is to examine the sufficiency or insufficiency of a cell to have formed from natural selection. I touched on that a little bit here where I pointed out some plausible scenarios that could kicked off the whole shebang. Of course, to rigorously examine this far beyond the scope of high school biology. The only reason for wanting students to think natural selection may not be “sufficient” is to try to seed doubt. Normally, doubt is a good thing of course. Scientists doubt themselves all the time, and if not, they’ll get corrected later if need be. But the doubt McLeroy wants to sow is that evolution may not work, and this simply goes against everything we know in biology. Muddying the water with doubt about well established scientific principles is not appropriate in a science class.
Next, we had stuff on how the universe formed. Somebody named Cargill seems to have wanted standards with more “humility”, recognizing that there are “other theories out there”. It was laughable that she couldn’t actually name any other these relevant theories. I’m also not too sure that high school students are prepared to go into discussing anisotropies of the cosmic microwave background and relation to various inflationary models. Is this what Cargill had in mind? Somehow, I doubt it. And these are the people deciding the future of education for our country? I shudder in fear.
It is frustrating dealing with Creationists, but I almost wish that they just went ahead and said textbooks needed to discuss strengths and weaknesses of evolution. If I were to write a biology textbook (which I won’t; I’ll leave that to actual biologists who know much more about the material than I), I would do this in the first chapter:
We will now examine the strengths and weaknesses of evolution.
Strengths of evolution: See the rest of the book.
Weaknesses of evolution: None.
