This begs the question that there is some valid distinction between evolution and the evidence for it on the one hand, and physical theories and the evidence for them on the other. I don't accept there is.
here should be a discussion in such classes of what aspects of evolution theory has merely to do with physical sceinces and what has to do with assumptions in the realms of epistemology, ontology, theology, and any other projections.
Evolution qua evolution is a scientific theory. No doubt some people load it up with a lot of other junk about the origin of life, determinism, etc. I agree they shouldn't. The other stuff is largely speculative and has the effect of weakening a well-proven theory in the minds of many people.
...culturally maintianed views of origin which may contradict aspects of evolution theories and which are not disproven, should also be treated, also for the sake of intellectual honesty.
That rules out Genesis, read literally, and all the other creation myths I'm aware of. Primitive people seldom used numbers like 4.5 billion, since you can't count that high.
Education is a conveyence of many kinds of knowlege and must deal with the perspectives, presuppositions and intentions of those who profess knowledge. (Hence, the modest word "professor" for one who used to be presumed to teach in the classic fashion.) Education is not a place for indoctrination of belief systems posing as physical science, whether evolutionism(s) or creationism(s).
Classic multiculturalism, I'm afraid. Evolution is no more a belief system than thermodynamics is.
