The problem with this, is that then "intelligent design" could have spurred by evolution
You have nothing to teach in ID. The class would be this long: "God/s did it"
When you are thinking on all the critiques on evolution you would want to put on that class, you are not talking at all about intelligent design. You are talking about evolution.
The problem with ID, is that there is 0 science to it. It has nothing to say by scientific standards. Evolution has many things to say,
including the things we still don´t know and keep figuring out or rearranging.
Normal evolution class:
Student asks "What activates DNA?"
Teacher "Uh, we don't know."
Student "Well why does evolution seem to go in the direction of more complexity."
Teacher "Uh, yeah, we don't really know why".
Student "Why does the fossil record show that species change suddenly and not slowly over time?"
Teacher "Well we think it's because species find a niche and evolve quickly into that niche."
Student "And somehow the whole species knows there is a niche available?"
Teacher "Uhh, yeah. That's the best thing we got now."
Student "So how did life begin?"
Teacher "We don't know but there was an experiment where amino acids were formed in a closed container and zapped with electricity."
Student "But amino acids are not alive."
Teacher "Uhh, no, they're not."
Student "Couldn't natural selection just be a factor in controlling population levels of species?"
Teacher "Well, if so then we wouldn't have an explanation for what causes all the species diversity we see now and over earths entire history."
Student "It sounds to me like you don't have an explanation for it now."
