Evolutionary biology is particularly hard to teach from "first principles" anyway. Once you get beyond the basic natural selection definition (variation, differential fitness, heritability), there's a lot of deeply unintuitive implications that only apply situationally, or mechanisms that result from the details of complex biochemistry. It's difficult enough to teach at an undergrad level that evolutionary theory classes are usually reserved for Juniors and Seniors with some prereqs.
