That sounds a bit over-wrought. I don't know about Kansas, I guess, but in Texas evolution takes a rather cursory couple of hours out of the year-long course. The rest of the year is spent with the usual Punnett squares, frog and pig dissections, body systems, cell anatomy, etc.
To be honest, I am often puzzled at how much time is spent debating how to teach evolution high school biology when it currently is really more "mentioned" than "taught."
and since evolution is really a theory coming out of a secular humanistic mindset...why can't ID or even creation science be "mentioned" in the same breath as all being potentials for origins?
