If evolution is central to biology, what did Garrett do in that class for a year? Perhaps it was something like biochemistry, which is also central to biology, or organ systems or phylogeny, or metabolism or photosynthesis or ecology.

But he wants to claim that weakness language prevents teachers from teaching science.

What was that link supposed to be an “example” of?

It’s an example of the testimony given in the SBOE meeting by people who have been students and/or science teachers in Texas during the last 20 years. In particular, this one is an example of a student testifying that his HS science teacher had avoided evolution altogether. I am sure that there are students in college who have learned about evolution despite not studying it in high school; but Mize did not demonstrate much knowledge of biology in his testimony, anyway — that’s not what he testified about.

I went to your example link, and Garrett Mize did not seem particularly ignorant of evolution nor did he relate evidence that teachers had been intimidated from teaching science. What was that link supposed to be an “example” of?
