One definition of science is that it is the matching of logical models (theories) to patterns of observations (facts). Some scientists focus on the logical models (the theorists) and some scientists focus on the patterns of observations (the experimentalists).

Any competent instructor (even at the high school level) will discuss both the models and the observations. A competent biology instructor will not only discuss that anatomy of various organisms but will also discuss the models the explain the similarities (generally, common ancestry and similar living environment; that is, evolution). Further more, a competent biology instructor will present classification schemes in the context of evolution: "this organism is classified with these other organisms because they have common ancestry."

Maybe Palin doesn't care if high biology instructors are even halfway competent - but I sure do and I'm going to taken that into account when I decide who to support politically.
