Within the sciences, we are often talking of phylogenetic classification; hominin and non-human primate phylogenetic trees are often introduced in a course in biological anthropology. Students are familiar with the hierarchy beginning with kingdom and ending with species; however, scientists often introduce subterms (such as parvorder, infraorder, etc.). In addition, these phylogenies are often complicated and changing. For example, while looking at non-human primates, scientists will choose to either use anthropoidea vs. prosimii or haplorhini vs. strepsirrhini to talk about primates below the level of the order (both suborders). It is often quite challenging to explain this to students who are relatively unfamiliar with the ways of classification- or in this case unfamiliar with how anthropoidea may differ from haplorhini (hint: this has to do with those pesky tarsiers). To address this complication, it is imperative to demonstrate how classification works at a basic level. This class activity introduces students to the processes used in classification, which in turn helps them to better understand the classification of living things.
