18 THE PROTISTS A. Introduction: Protist taxonomy is currently in a state of flux. Nucleic acid sequencing and cell structure studies have given systematists evidence that they can use to begin sorting protists into monophyletic groups. Campbell and Reece (2005) note that some systematists have split the protists into up to 20 kingdoms to more accurately reflect the evolutionary relationships among these organisms. You should be aware of the current state of protistan taxonomy (see Figure 28.4 in Campbell and Reece (2005) for a nice summary), but today we will focus on simply observing a wide diversity of protists. Protists are the most diverse of all the eukaryotes and may exhibit a range of animal-like, fungus-like, or plant- like characteristics. These characteristics are often considered when studying protists, but it is important to remember that they have little basis in either phylogeny or taxonomy. The Protists are also very diverse in terms of their sexual life cycles.
