That’s a good idea; it’s tempting to believe that a category is less fuzzy in reality than it really is. I would point out recent examples of speciation including the subtle development of the apple maggot, and fruit fly speciation in laboratory experiments. If you want to further mess with their concept of species, tell them about ring species (which are one catastrophe away from splitting into two species).
