The instructor can ask them to analyze whether speciation has occurred in a particular story, and if so, what reproductive isolating mechanisms have evolved; to distinguish Lamarckian versus Darwinian thinking in an author's writing (for example, by analyzing Spiderman's acquisition of powers from a spider bite); to observe how natural selection has led to adaptation and how drift has caused random changes in a given population.
