" that there should be contrary evidence to Lucy presented in high school text?"

I agree that Lucy should not be presented as conclusive in isolation. Any legitimate presentation should be accompanied by a qualifier or disclaimer. I don't think that high school science is going to do much more than scratch the surface anyway.

Any legitimate presentation should be accompanied by a qualifier or disclaimer.

Now you have my curiosity, what "qualifier or disclaimer?"
