The so-called scientific method, a real life example, and more on the importance of the imagination in science.
Creativity comes into play at more than one point.
The study of biodiversity has lagged far behind other sciences. Consider, for example, that Copernicus established the heliocentric universe in his 1543 treatise, and Newton established the physical laws governing the universe in the 1600's, yet Carolus Linnaeus ' final edition of his Systema Naturae listed 9000 species of plants and animals. Surprisingly, we still can't answer that question. We can't even say with certainty how many species have been identified and named. There is no central repository for information on all life forms.
