This chapter follows how the grouping of living things changed from Aristotle's trees, shrubs and herbs to Whittaker's five kingdoms, and why each change was made. It then walks through the three kingdoms made mostly of microbes, Monera, Protista and Fungi, gives a short sketch of Plantae and Animalia, and ends with the things the five kingdoms leave out: viruses, viroids, prions and lichens.
